All right, tell you what I want the dope of me deal if you fix it you can daily it as far as I'm concerned. Oh, yeah
Oh my god, it worked. There's nothing more satisfying than
Having a result like that if I'm being perfectly honest. Let's button it back up and see if we can fix that battery problem
I don't remember where any of the screws go and at this point. I don't think I care anymore
The battery issue may be related to this guy. There's some context here that might make it think that it's broken and
It isn't so let's get this side back on. I've got this millimeter thick
Tape double-sided tape which we can use to
Repair the the case backs and things like that which will be pretty nice
It's not going to have any water rating anymore But I don't think that matters at this point get some of these screws back in here
See if we can get it functioning again. There's a bigger screw in this one, which I think I've lost
But whatever. I'll just put one of these in it'll be fine. I think it's one of these anyway. Yeah, it is
It's precision drive is great
I like the big but it spins forever
It's true gently pop this screen out again. We don't want to be damaging a ribbon cable now. I'll tell you that
There we go, there's our screen. We got some screws to put in here
And we got this side plate to put on as well that goes on here first whichever way it comes out goes in like this
There we go, and we got the rest of the screws for up here. We've got a little
clip here that's gonna go back in
Crunch it's always a good noise. Don't forget about the bit storage
last one up here I Can get it. I think that's all the screws. What's that then? Did I forget something? Probably do I care?
Nah, I put the old one back
Whoops. Oh, well Not really. Does it like need the other screen?
Please work. We're waiting for these two guys to go away. I don't know if it's supposed to take this long
It's murder it. It just turned on immediately It's a good sign. This is less than promising. At least we can come from here and have a poke around I guess
That might do it. We're getting a very different result now, which is interesting
This is a very good sign Especially that it's running
Without the charging cable. We weren't having that before right and I think that was because we removed that
that base piece over the Charging port a lot of the times the temperature sensor for the charging port there we go
We have 54% the charging port will be responsible for
Managing the battery temperature why the thermistor is there and not in the batteries themselves. I don't know
Let's get the charger in and see if we can get a charging indicator. No, okay
But the phone is working now one thing that we may need to worry about is maybe some sort of battery
Recalibration procedure because it uses two batteries that need to be charged at the same rate and these ones kind of aren't at the moment
I guess we have to use this side. If I close this down. Do we get clock here?
Yeah, we do. Let's actually have a think about our temperature. Just move that over there gently
We're doing okay for temperature. This screw isn't
Screwed in all the way. So we're 54 percent. We're getting that blinking. Okay. Well, let's
Shut it down. I have to enter my pin to turn off the phone. Well, okay. Well, you I
Don't really need a spin At least I don't think so. I don't think I unplugged anything on this side. Of course, it's turning on again
Can you not do that, please? Come on. Go into the boot loader
Okay, let's have a look at the charging port that might be where our problem is no promises
But we'll find out cuz I was screwing around in here and it's possible that I
Knocked on something so theoretically looking this into do nothing because I just removed the whole charger board
Okay, cool. We're doing this with the phone on for some fucking reason
But whatever you may have to restart the phone after disconnecting the charging board
Let's have a look underneath this guy because I may have dislodged a cable or something
That's always a possibility. So this seems to be a pretty important cable
Get that back in and make sure it's seated properly. I don't actually know what it does, but I don't think I care
Okay, now we're getting our thing again. What could be happening?
What could be happening? One thing that could be happening is the other battery is actually
The problem. I mean, we're saying that it's too cold, right? And that's why it's not charging. So if this is our
Connect for that that's our connect for that and I hate doing this while the phone is on
But I don't really have any other choice because I don't have line. This is pin and I can't turn his
Off. Let's try this. We'll disconnect that for that one battery. Let's see what we're getting now
Okay, interesting. So it's saying that it won't charge
So my thought then is our problem is going to be in this side the temperature too low indicators is a weird like
generic Error that generally never means that the battery is too cold like ever the screen is. Oh
Thank you. I don't know. I'm breaking another screen. Do it
Thermistor is not connected and it's just like I don't know what that but the help let's take this boy apart again
They're connected by a Pair of connectors through the hinge and this one here says sub on it
And this is probably the interconnect that goes through the side of the phone and and plugs into this board
There's going to be logic and power It's going to be like a weak form of logic, but it's basically just more like an interconnect to you know
We've got the camera over here and a couple other things too, right? One thing that I'm going to do
Phone still on plug in the charger. It says
It's charging there. Hey, I fixed it. Why did how did I fix it?
This is the new one maybe this battery here just wasn't pushed in all the way that's the only
Thought that I have about that. Let's get this guy back in make sure that's all nice and snug
Down there. Okay, we're still good. We're still golden now. I removed this entire cable
So maybe I should plug that cable back in. I don't know what it does, but it might be important. I mean
It's a bonus cable. They just give you it's probably
Like a bunch of data and important things especially as it's coming directly from the charging board
I mean that might actually just be the charger for this battery and that is probably what it is to be perfectly honest
So let's see if it charges here now. It doesn't okay good
So it's noticed that the batteries are mismatched, which is interesting. Okay, what I'm going to do
Is I'm going to trick it so we're going to plug this in and
It doesn't like that. Oh, this is very interesting. Okay, so we lose this cable
This is kind of the fun part about troubleshooting is you just try stuff until you get a different result
And then when you get a different result you kind of go back and figure it out. So we're getting that error again
Which is so interesting. I don't understand. So whatever the hell this thing is this probably has
Some sort of thermistor something. I don't know. I'm just guessing at this point that may be measuring battery temperature
Come back in here. We'll plug it back in Doesn't like it. Let's lose
this guy Theoretically it should do absolutely nothing. We'll plug this back in
Charging no
interesting Interesting. Oh now the phone's dead. Cool. So this battery is working, but it's probably just angry
Yeah, there's one thing that you can do would be to leave the phone on until it dies as a form of recalibration or
Charge it to a hundred percent if we can get it charging again
It would be interesting to see if that works. I don't necessarily think it will
But we'll give that a go draining is generally the better option. It's just more irritating. Oh, that stayed on
So it like it wants to turn on kind of the behavior is so strange
I'm not used to devices with two batteries normally they've got one and so it's easier to troubleshoot that way
But when you have multi-battery and the battery management system can be a little bit confusing
Especially as each battery has its own little brain and it might be expecting something that it's just like not getting
So let's try and plug this back in. It's obviously happy. So we know both batteries are
Functioning again. I'm really just kind of shooting myself in the dark. Look, we've shot down to 24% battery
Which is very interesting. So this is probably a good sign
What I'm going to try and do now is I'm going to try and remove the secondary battery and see if the phone shuts off
Which I fully expect it to yeah immediate which is good. So if we just keep
f***ing with it either something is going to break or
Ephyxy my one concern is that I might have
Moved something under here. So let's lose these guys as well. Okay. This is kind of cool
That's our wireless charger. This sub cable is not what I thought it was. These are all nicely down
This battery is not warm, but that one's down. So this sub cable
Interesting that's a very interesting multi-layered circuit boards here. Let's try and turn it on with that
It's okay with that Yeah, it likes that and see what our percentage is now now we're at 47% it has no idea what's going on man
It can't figure out what's going on. We did get it charging once
Which was really interesting and I I don't know why but I did put this guy in
Like maybe it has something to do with pressure on a certain area in it
I don't know if it was that interconnect cable. I don't know what's going on. I don't know where I am
Okay, that's still not functioning Let's go back through our steps that we were doing before let's lose this guy because we can get it charging
And we can plug everything back in And see what happens. I don't know where the thermistor will be
We'll just go through nice and slowly see if we can trick it into actually delivering power
Where I would like it to now. It has no idea
That the charge is in right so this board is completely disconnected now. Let's throw
This guy back on this is some communication cable. I'll be careful not to short anything at this point
So we know that this cable does nothing and this is going to be our cable that deals with our charging and our power delivery and
A thermistor and everything like that. Let's see what it thinks about that
assume not highly Same sort of problem
This one yeah, yeah, that's the the NFC now this may actually contain a thermistor
What is what is that? There's something here that looks like it could possibly be a thermistor, but I'm not entirely sure
I'm going to rip a couple of these other guys out
See if the phone turns off. I think the phone turned off one thing
That we could look at which might be why we're seeing this behavior actually is
The corrosion on the cables
And I've lost a screw the corrosion on the cables
That we're under here We can't
Because they're the interconnects between the two halves of the phone and that level of tear down
We will be here for days This one was pretty okay, but this one is not we've done hard reboots. We've done soft reboots
We've done the anime reboots. Let's try a harder
Start maybe that'll work now. We're not booting at all
This is this is great. Oh Oh, it had booted. Whoops. Okay. We're still showing 46 percent. What if we do that same issue?
What if we do That now it doesn't think we're charging and we plug that in and we're charging so we tricked it
So what we'll try and do now. I'm not gonna I'm not gonna touch it
I'm just gonna basically let it charge up to a hundred percent and think that it's a hundred percent
Because the internal battery BMS should trigger and stop everything
So what that'll do is a recalibrate the software Hopefully then it'll understand that it has two batteries that are the correct
Stop charging the same issue. So I'm full of shit, but at least we know how to trigger charging now
Yeah, yeah, that's a good use of everybody's time and now we're getting the temperature icon again any thoughts on the temperature icon
Apparently it's gonna start Disconnecting more things because either it's not detecting the thermistor
Or there's a battery mismatch or or or lots of stuff
I mean, I'm feeling warmth on one of the sides at least maybe we do have to switch the
The charging board be interesting to see if that fixes it. I have some suspicions as well, but we'll we'll find out together
I guess it's a journey of discovery
Let's get this guy out of the way It's a pretty pretty keyboard
Oh, yeah, that's full of Thanks to Jordan we might have our might have an unblock
Yeah, some of the contacts look actually fine. We'll have a think about that
So we didn't get water in this side, which is great. I'm gonna just pop this back in and we'll we'll give it another try
It's nice to see it turn on every single time. I'll tell you that we have 56 battery now, which is very strange
Now it's not even taking a charge. Oh, this wasn't plugged in all the way
Now that's what we were doing before to like spoof it So let's see if we can gain a percent or if it's gonna freak out
It's angry again. Why should unplugging and plugging in the charger multiple times fix it? That's kind of interesting
Okay, we're at 57. That's that's a more percent. We've gone up a percentage
But it keeps failing over well This is being more consistent now and every time it goes up a percent it fails over and is upset, right?
So we're 58 percent now. We're now in the in the kind of the territory of
Bms freaking out because the batteries are different. That's my thought at the moment
Like it's saying low temperature warning But it's not a low temperature warning low temperature warning to me is very very interesting
I don't have a reading something is something is broken. It's upset now. That's for sure. It's interesting this board popped up
So I wonder if there's some contacts on the back of the
Charging board here that are responsible for more than I think
Let's try that interconnect trick again
Interesting. We did get a percent into it, which is nice to see. I'm going to do another reset and see
What happens after that? I assume the behavior will be the same
We may just need to let the phone run and die. We're getting to the point where
I don't know how much longer we should spend on this. We're going to try wireless charging
Anybody got a wireless charger? I might be able to do reverse pd
I believe I have the functionality for it. We're going to need the charger back in first
We do need the contacts to make contact so that they can contact
I do not know if it'll take it, but we'll see
I
Worked for a second. Did I get an error message? The battery has stopped functioning. Please work. Okay. I actually think that it is a
connection with the back of the Phone because I was pushing down hard on this and then it took it. So
Let's try some quick charger that's on there
All right, and it's still freaking out. Is it freaking out?
No, so we're freaking out
I'm going to put my finger here. It don't like that all
Very interesting. Well, we'll hold off on that for a second. One thing that I want to try is putting my finger here nice and hard
No, okay, so it probably wasn't that I think we're still looking at issues with the with the charging port there
So it might be time to rip open the other one and let's see what happens when I release my fingers
I mean I might be full of s***, but yeah, there it goes I think it might need the pressure of having all the screws and things in place properly
We gained another percent there. I think I think this is probably a red herring. Oh, maybe maybe not. Oh
It's hard to tell there may be some issues with these guys down here. So down here on the bottom left
We've got these three contacts which ground the side of the phone right right there
And if they're not seated properly, we may be seeing
That problem. So I'm going to pull The board down towards me. See if it likes that. It doesn't seem to so what if I push down on these
Two connectors right about there. We grip the phone from here
Anything No, it doesn't like that about that. How about that?
Right there is our magic spot
Interesting interesting Okay, I'm going to pop these out and I'm going to pop this charging board out again
And we're going to have a look at those contacts because there may be some sort of
Corrosion or something. I'm going to give them a little bit of a scrap grip for you
They're a little dull. They've got a little spot on them probably where that
Connector was coming from Once over might help. Who knows? I don't know what is real anymore. There's a lot of little teeny tiny
Connectors, I don't know too much about usb-c. I don't know if the
Case acts as any sort of grounding plane probably not wouldn't make a lot of sense
I'll get that back in for the third time. I don't know how long has it been now?
75th time like doesn't really want to seat right here
Okay, the thing that goes on top of the thing is now in pretty steady
Yeah, and now it's angry again. So I put pressure here
It still doesn't like that. Yeah, I don't know. I think I'm full of too much pressure not enough pressure
I mean we can just start going ham now and changing things. I don't see anything wrong with that
Move this over to here So we don't have another repeat of the other phone
I think we're probably barking up the wrong tree. This doesn't feel
Logical to me this driver board would be causing this problem, you know
You know what I mean, David? Yeah You know what I'm talking about? Yeah, you're picking up what I'm throwing down
There that went a little
Less eventful than the other ones wonder I forget to reattach on this one nothing nothing give me your board
I want to go home the
Oh That explains a lot. I forgot to put three screws back into the usb charging board which may explain
why me pressing down was fixing a couple things
because It actually needed the pressure and my
Fingies Weren't enough, but we're in here. We might as well change it over. No, that one's nice and clean. It's never been used
Now watch me put the old one back. Yeah, this is the new one
And just tastes like youtube comments, let's put the phone back together properly
That looks better. This is where samsung puts their thermistors and this works then
be very very amazed to be perfectly
honest
And it has two batteries. Yeah, it's gonna work, isn't it cool? It doesn't
Well now, what do we do? So my initial thought is
correct then in that It's angry
Because there's a something That's not behaving properly. Have I remembered all the screws from these?
Yes, it looks like I have that's in that's in that's in that's in
That didn't sound like it was in it sounds like it's in now. Let's try that
Maybe that board was not in properly
No, my thought is this cable is somehow slightly damaged because there's going to be a thermistor on the
Board attachment here for this battery anything
No, what if we do this again? I'll rip that off
I'll plug it back in So it's charging again after we plug and unplug that board
Probably because we're tricking it. I'm out of ideas
My assumption that it is so how do we drain it real quick?
I don't know I'd like to see how long it lasts attempting to charge
Forget to 58% now there it goes it gets to 58% and then goes like
My batteries don't work. Please stop. Maybe we just keep doing this until it starts to continue to hold a charge
No, see it doesn't like that now now. It's angry. I think what it's doing is it's like
It's doing a voltage measurement every percent, right? So it gets to 59%
and then Falls over so if we wait for that to drain and then we'll plug that back in again
If we just keep doing that my assumption is that eventually it'll get to a point where it'll continue
And I don't know if that's 100% and I don't know if it's 60% or anything
I mean what we do We've already taken this one apart. We just put the other battery in it. My assumption then is that the batteries will be identical
and And the bms's will Kick in and then they'll be happy. Well, that's the thing is I'm not entirely sure
It's probably going to be a centralized bms And then each battery is going to have its own right those are those little
Strips across each of them on the top
So let's start ripping this one to pieces and see how quickly we can do this just a quick repair, right?
Yeah Well, I think I remember being told something like that. We figured that the batteries
May be mismatched and that's kind of causing the problem Question for you. Yeah, does it still turn on? Yeah. Okay, because I didn't back up my whatsapp yet. Oh, okay here
Go ham. Oh what you charged this one? Well, this is the one that I'm trying to make
Work and charge. Oh, we can get a percentage every once in a while. You can consuming alcohol at work today, sir
So, I mean the phone's been drinking it. I have a lot of messages from a grand total of
Seven people Off whatsapp for over a month
Isn't that sad? That's amazing. That is my entire social circle and
That sounds pretty good. One of them is a family chat One is a missed call from someone who only contacts me when they need tech support
Oh, that is probably worse and one is a group chat for one of my kids lessons
So that leaves four Geez my family
Geez, I joke a lot on the channel about how I don't have friends
You have us and you're great
That felt good and it didn't start catching on fire. So
We have progress. I mean, I could just not fix it if you don't want to talk to your family or a friend
Disintegrating whatever the hell that is. I was talking about doing an internal bedding pool for the start time of wancho
You gotta buy doughnuts on Tuesday or something. Oh, you got the battery? Just about it's still time for it to catch on fire
Oh my god There's some payoff on that
Yeah
