Hi, my phone has some serious issues, inlcuding not charging and battery draining fast. I have not been able to backup files since this started to happen, as the phone would normally just turn off saying the battery was dead. I tried replacing the battery and the usb charge port, to not much success. The power button has been broken since a drop about 4 months ago.
I'm looking at putting my good motherboard into a phone that is still completely functional.
My question is, if I put the motherboard of my phone[dead battery] into another htc one m8 [siblings old m8], would all my pictures, documents, and files be there on the new phone? As far as I know the motherboard is the entire phone, right?
Thanks for your help.
As long as you don't damage the board when you are transferring it between phones. Or you don't damage the working phone while transferring the board then you should be able to get your data back. Thing is you claim that you have a dead battery which would mean that you would have to take the battery from your siblings phone and use it with your phone to make sure it will boot. Check on how to replace the battery.

Since I got my T989 I noticed it gets hot even during moderate use (Using the browser or making a phone call) and drains the battery so fast that battery level sometimes drops a bit even while charging.
More than a week ago, I shut it down to save some battery. Ever since, it wont turn on in any way as if it's hard bricked (Not going to download mode through jig and not being recognizable through usb). Only thing it does is charging the battery, and getting hot while connected to charger (No vital signs other than that).
It did not happen while flashing a new rom. Last time I flashed new rom was more than a week before that, and used some app to underclock in order to save some battery. Nothing other than that that could mess up the boot loader.
What are the chances it is an hardware issue rather than software?
And if so, what checks can I conduct in order to confirm? What can cause the processor to overheat? Will reflashing the phone with jtag protocol be able to solve this?
I have got no warranty on this one, so either I get this fixed or have to replace the pcb (if that is even possible).
Hello everyone,
I've been trying to pin down a problem with my AT&T GS3 for the last few days and I can't really find anyone describing quite the same symptoms (or maybe I'm slow and missed something somewhere). The problem seems to be that my phone isn't recognizing the battery has a full charge more often than not. It started a few days ago and seems to have gotten worse, as in when I first noticed the problem my phone would still turn on for brief periods of time before failing to 'see' a charge > 0% and then dying. Right now, it just powers up ever so briefly- sometimes it'll just die after it says Samsung or briefly into the boot screen.
Today, I took it apart to inspect the motherboard and connections but I didn't see anything obvious like broken connections or burny, burny components, but idk, everything is small and I didn't have a microscope. I wish I had looked closer at the power IC chip and stuff like that but I'm blind and probably wouldn't have seen anything anyway unless it was super obvious.
Occasionally, instead of showing a sad empty battery when I power it on (plugged in), it'll show 100% like I would expect and it would get slightly further into the boot sequence before dying again and go back to showing empty and making me very sad and confused. I can almost swear this happens more often when I'm holding it a certain way or whatnot. One other thing I noticed is that when this first happened, my battery was about 32% and after a while of 'charging' it would show 86% when I got the 'correct' battery charge to display... next instance was 94%, then 99% and finally 100%... so I can only assume the battery is somehow charging but the phone just hasn't gotten the memo. I bought another battery (OEM) and tried to no avail, so I assume it's not the battery. I've tried multiple chargers and no luck there either.
So, has anyone ever seen anything like this? And if so, do you think it's the power IC, the capacitor in that circuit, or something else that I'm not thinking of entirely? I see that there's 4 battery pins/terminals/whatever and after internet'ing around a bit about phone batteries, it seems that 2 are the normal pos/neg (obvs), one is a thermistor for temperature, and one 'talks' to the phone to tell it all about the battery's voltage, charge, etc because the old way of indicating charge was kinda shoddy apparently. I'm definitely suspecting something to do with that last thing too, but I have no idea what part of the circuit that is.
Any sage wisdom here would be very, very appreciated and thank you in advance.
P.S.
I have some background working with electronics, but not electronics for ants, if that helps at all.
Done / Fixed
Never found out what was wrong with the motherboard but I did buy a GS3 w/ a broken screen off eBay to do the fix for cheap.
$100 (broken phone) - $65 (resale of parts) + unscrewing/rescrewing 10 tiny screws + detaching/reattaching some cute ribbon cables = phone worky worky
If you have an S3 or similarly easy to disassemble phone, I'd highly recommend doing some research and ebay scrounging before dropping a metric crapload of cash on a expensive repair or replacement.
My friend gave me his HTC One X to fix (PJ46100) and he said it has been dead for months. After a few diagnostics, and about 30 mins on charge and 10 mins in my PC, it isn't connecting to the PC, I have no word from ADB, the phone itself has no LED light showing, no vibrations, nothing. My aim here is to get it on at LEAST in fastboot/recovery mode. I have never used a HTC One X but being addicted to my 4.3 Desire, I know how the usual HTC fastboot works. I know its power + volume down but is there any other way? I remember my Desire was Power + back button, EVEN though everyone online said it was Power + vol down.... Does the One X have another method?
My mate wants me to get his photos off it, and thats it, its mine
So yeah, any word on what it could be?
Doing loads of research, its a 70% chance of being a battery issue and a 30% chance of the board being dead.
I am not afraid of taking this baby apart so go ahead and ask your questions.
Thanks guys.
(BTW - I may be posting from another account in my replies....)
Hi there, I also have the same problem as yours. No led when charging, not detected by pc, its basically a paperweight. I also had done my research and I can conclude mine is a board issue since the problem occurred after transferring some files from pc and the battery is perfectly fine then. If you believe battery is the culprit, try put the phone in a sealed bag and put it in the freezer. It might bring the battery alive. I have took mine apart and I noticed that during charging, the board will be warm and same goes to the battery. This would suggest the phone is taking the current from the charger.
same problem here
I've revived dead phones where the only issue was that the battery had lost so much charge that it wouldn't charge via the phone's charging circuit e.g. Desire S and One V. Removing the battery and charging directly using another device solved it both times. Got to be worth a go. There's guides on removing/replacing the HOX battery on XDA. Just gotta go carefully!

Hi there dude.
I just replaced the battery, and yeah. Even without the charger, the board went warm for about 45 seconds. Charging does nothing, even with the new battery.
So I am guessing its the board.
Ouch.
This isn't even mine. My mate had this collecting dust since it broke about a year ago and he asked me to see if i fixed it.
His dad wanted some pictures off it, so I guess they are out of the picture (pun not intended, but eh.)
Anyway, do I buy ANY board or is there a special board for this model number?
eBay brings a few up when searching "HTC One X".
Cheers guys for the replies
I had tried charging the battery using the external charger and after connecting it to the board, it became warm and after few hours, it subside. I checked the battery and the voltage is 3v, the minimum discharge voltage. So i can say that the board suck the power and change it solely to heat. Is your htc one x tegra or snapdragon version?
Hello,
I bought a used T-Mobile HTC One M8 a couple of days ago off of eBay. While it's a cool phone, I've had a serious issue with the battery. When plugged in, the phone works fine. However, after being charged for several hours and removed from a power source, the battery will read 100%, slowly dying to around 96% or so with use, and then shut off randomly without warning only a few minutes after being taken off the charger. It won't give the normal "shutting down" message; instead, the battery will go from whatever percent it was to 0% and then the screen will go black.
From what I've seen online, the battery might be bad. s suggest that this problem results in an inflated battery. In this M8, I noticed that the left edge of the screen was almost separated from the metal bezel as if something was pushing it up from behind. This makes me think my battery might be bloated, causing the battery issue and pushing up the screen.
I have tried wiping the phone before flashing Lineage OS instead of the stock ROM, fully charging the battery up, and fully discharging the battery, but nothing so far has worked. Do you have any tricks I could try that might fix this if it is a software issue? Or does this seem like a bad battery that would have to be replaced?
If the battery is bad, the M8 doesn't make it easily removable, so I would either have to take the phone apart or send it in and possibly pay someone to replace it. The previous owner said it was working fine, but I have yet to hear his reply to my eBay message asking about the issue. He included all of the original packaging, including the original limited warranty. While the warranty is probably long expired and technically doesn't transfer over reselling a phone, do you think there is any chance that HTC or T-Mobile might be willing to fix the phone or send a different one?
Thank you for any help you can provide.

Flash t mobile RUU (software problems will slove with this ) . If the issue still there ,then it must be a hardware issue i.e faulty battery or some other.

The battery in my M8 is really weak now, and as of maybe 6-9 months ago the phone is not tracking the battery level well. When the phone is idle, it powers off at 20-30% indicated charge remaining, with games active, maybe it will power off at 45%. I get 1 hour PoGo from a _full_ charge.
Previously, I've experienced the phone getting hot when charging (mainly in the car) and this has probably had a serious impact on the battery capacity. Assuming the phone you have is over a year old, you should assume the battery is badly aged by now.
my adorable M8 in his third year of use recently has the same symptoms of @tshoulihane. Is necessary to say that I've took so much care in his first 2 years like disconnecting the battery after few minutes of reaching the 100% (also voiding to charge all the night) or turning off the phone at 10% and I never be waited for the auto turn off at 0%. All this that I'm telling you is in the first 2 years. In this third year of using the m8 as my main phone, I received this bad symptoms doing the opposite of the first years of care. Now I just connect powerbank or something at 30% to void awkwards sudden death of battery. Mmm I have plans to keep 1 year more my m8 with me, it still a beast in camera, sound and no lag, so I'm looking for a battery replacement im Amazon but the reviews are bad, I think is very difficult to get a good *new* battery because that replacements get old too with the years of storage... mmm I don't know but this was my little story with my battery experience with M8. Regards guys.
My G3 (D855) is now not powering up at all. When I turn it on there is no reaction at all. I luckily have another "test" G3 and I have tested the battery on that phone. So I have 2 batteries and they are both fine. The only reaction that I am getting from my broken phone is that it does charge the battery. I only know this because I can measure the battery level in the test phone.
I need to extract some information from the phone. My test phone has no value so I thought about following some youtube videos and moving the broken phone motherboard into the test phone. Another option is to heat the motherboard in the oven.
I don't know if the problem is the motherboard or elsewhere.
Before it died completely, there were some problems. Here are the last reactions that I had from it:
The battery was at 70%. When I try to restart it after taking the battery out for 5 minutes nothing happens. Completely dead. But if I take the battery out for, say, 5 hours it displays the startup screen for about 10 seconds and then dies. Then immediately trying to restart it does not do anything. All of these tests were done with the charger connected and then with the charger disconnected. The charger made no difference, and it is a working charger.
So I would like some suggestions that might save me from changing the motherboard.

Changing your motherboard won't help because if you move the dead motherboard into your test phone, your test phone will be dead. The motherboard is your phone with a case on it. Only thing that might work is putting it in an oven.

Does that mean that even if there is a problem with the peripheral units or the power supply but the motherboard is good then the phone will always show some signs of life?
