Hey all,
I have a very odd problem with my old P500 I am trying to get running again. Almost all the time the phone wont turn on. I have tried removing the battery and leaving it, plugging it in both with and without the battery, trying various different reset combos with and without power or battery in the phone, nothing will work. Usually. Then sometimes the phone just turns on. When it does work, its great. All until you turn it off again. As soon as you turn it off, its a guarantee it's not coming back on for a while again.
I cant seem to work out any rhyme or reason as to what will let it turn on either. I have had it turn on sometimes on a charger with no battery, sometimes charger and battery, and sometimes just on battery without a charger. Like I mentioned, when it works and will turn on everything works exactly as expected. I can't find anything software-wise that seems to indicate it wouldn't load. Just most of the time (upwards of 95% of the time or so?) it won't turn on at all. Hard reset combos etc have no effect on the phone, and it won't pull up on a computer in this state either. I bought another battery recently and tried that, as I had previously had a poor battery life from it, but that turned out to have no effect on the booting issue. The most recent time I was able to boot the phone I left it on and charging for a few hours and it finished completely charging the new battery, but on turning it off it wouldn't come on again as usual.
I am suspecting a hardware problem with the phone internally, although I am not really sure. Anyone else have any clue as to what I might try? If it is hardware-based, does anyone have a suggestion as to what part might cause it not to boot?
Thanks,

I get my hands on a Desire S, that refuses to turn on. Now the battery is charging in a another one, there are no problems with the battery. Any suggestions what to try? When the battery will be at 100 %, i try to turn on.
When phone is charging, is there the LED orange/green? You can try the following. Plug in the phone, and while is plugged in take out the battery and try to start it up without the battery (but still plugged). I know that there was something like this written in a topic, when someone adviced to turn the phone on, then take out the battery while it was booting and the phone will still run even if the battery is out. It could be something similar with some laptops that can start regardless of the presence of the battery
Ok i now tryed to turn it on, even with the cable, nothing. Seems there is some hardware damage. Seems i have to buy new mainboard. Anybody got for sale a desire S with damaged screen ?
Hello,
recently, my 7Pro drained all the battery and turned off. When I got home, I plugged it in and waited to finish the charging. After 20 minutes I noticed that the phone powers on, put the announcement that the battery is critically low, stays on for about 3-5 minutes, then turns off itself. After that it shows big battery icon on a screen and nothing is happening. Again, when I plug the cable out and in again, the phone starts and behave again the same (stays on and then turn off by itself).
Does anyone encountered similar problem? Could it be faulty battery? I've tried 3 different chargers (including car), tried to charge it from my 2 computers, tried charging while in bootloader mode, also I've reset it to defaults (+; - ; power). Nothing helped so far.
I have it still in warranty, but I have cooked ROM made by ansar. I'm a little afraid to send it like that to HTC.
Any advices greatly appreciated!
Thanks!
OK,
I will answer myself
Do not give a phone to your younger brother! Little brat somehow changed USBMode to "diag" and uninstalled the app! I have restored the phone to defaults and managed to check that before it turns off. After switching to Zune mode, the phone is charging without any problems.
So anyone having similar problem might want to check it out before panicking like me.
Hi everyone,
I have several problems with my AT&T 8X. First, the screen keeps on cycling through the brightness level non stop, so its constantly changing the brightness. I've tried to turn off the auto-brightness but that doesnt seem to help and this only happen after the phone booted up and I touch the screen so Im thinking it's a software issue. ANother one is that when the phone is one, the computer wont recognize the phone and it won't charge, both AC and PC charging. To charge the phone I would have to power it off and plug it in. It wouldn;t have been so bad if it wasnt for the fact that whenever the phone is power on again, there's a high chance that it will boot loop and I'll have to do a hard reset to fix it. All of these looks to be software problem to me. Hard reset doesnt seem to fix them though, does anyone has any idea?

Never faced any such problem till now Try visiting htc service centre Or try draining the battery completely and charge it completely before using Sometimes solves my screen related issues

I actually did drain the battery and charge it up again. I had to remove the screen though since it wont charge keep keep boot loop every 3 seconds. so I had to take out the screen and charge the battery separately by manually hook up the wires to it. And htc service center is no longer an option since it is no longer under warranty, which is why I opened it up in the first place lol.

You'd taken out the battery?? Thats a really hard work!! Battery is hidden inside right? and we'll have to remove everything just to reach the battery!! Did you do it on your own? I'd actually heard removing battery is very dangerous and we should be very careful since it's behind the screen and the connecting wires are too thin :silly:
If you take off the screen, there's a cable that connect the screen and the components to the battery, all you have to do is unclip the cable and hook the wire to the battery correctly (positive and negative side) and just plug it in to charge for 30 mins. Since the phone won't turn on, the battery left to be charged fully rather than keeping going into bootloop.
You don't actually have to remove the battery, just need to separate the screen from the back.
Ok, this is a weird one. I have searched everywhere to find out what this is but I have not found anything. A lot of problems are similar, but nothing fixes the issues.
Issue is this. I turn my phone on and it goes all the way through the boot sequence, and turns off when it gets to the lock screen. I formatted the phone, and I get all the way to the setup screen. When I touch the screen, it turns off. I connect the charger to the phone and turn it on. We are fine here. I use the phone and do anything I want. As soon as I disconnect the charger, it turns off.
Just noticed this as well. My menu and back buttons don't work. I don't know if I disconnected something when I looked at the board, but it may be a symptom.
Any ideas here? I am thinking the battery, but I don't know why it would do that when the battery is charged to 80% and holds the charge.

Had the same issue recently.... The battery needs to be replaced. The battery I had went bad and the only way it would even work is to be constantly plugged into a charger, dc current not ac from a battery like a car.
I killed the battery not on purpose but learned a huge lesson from utilizing fast charge from a custom kernel constantly
From my S3 on Wicked 4.3
so yeah, my phone just freezes randomly at different time.
I believe it's freezing and then it just drains the power.
When I turn it back on, there's a gap in the battery life. Unfortunately, this time it must have happened really early and the battery drained to 0 and now it doesn't even power on.
This includes power + vol down with and without charger on for at least 1 or 2 mins, nothing happens. The notification light turns on when you plug it in.
I believe I do need to open it and unplug the battery then plug in the power, but I can't test it out because I don't have T5 torx around so it may take a while.
Anyways, I am not definitive on the freezing, it's just most likely scenario since phone becomes unresponsive randomly.
When it happens, plugging in power, power button, plug to usb/data does nothing. Phoning the cellphone gets user not in service. And powering back on I see the battery is drained.
This started happening like around a month and a half ago, I was using SaberRom. The rom was very stable until it this started happening.
I thought there was a bug in the Rom or something, so I made the jump to CM12. However it still continues to happen.
My only guess why this may be happening, software wise now, through the process of elimination is maybe Xposed might be doing something.
If it's not, then it could be a hardware problem, which doesnt make much sense to me since the phone is stable when I actually use it.
The freezing problem never happens while I use it, it usually happens over night or not in use in my pocket.
I started using logcat to try to keep a record, but I only have 1 record, plus 1 the most current one which I dont know if it even recorded properly since I can't turn phone on.
I personally would do a full wipe and flash stock ROM and kernel without Xposed. Until you do that you really are just shooting blind. Find out if the problem goes away and go from there.
