[Q] Mytouch 4g randomly turns off, wont turn back on until the battery is pulled out

I have had three Mytouch 4gs replaced because every one of them I get turns itself off and wont turn back on until the battery is pulled out and put back in. This happens about 6 times a day.
I have tried a new SIM card, new sd card, new battery, factory reset, factory reset with a format of the sd, and they still turned off even without any apps installed and not signed into google.
I am baffled. Does anyone here know what could be wrong here?

i dont know why this has happened to you so many times but it happened to me this morning and immediately after the battery was pulled and reinserted i went to rom manager and fixed permissions. took a while to finish cause i have buku apps but hasnt happened since.
hope it helps ya!

I was running completely stock when this happened, but I've since upgraded to virtuous fusion. Is it better to boot into recovery using CWM to fix permissions or am I fine doing this from the app?

Well I fixed permissions through CWM and it just turned off on me again. Ugh. I'm guessing its not a problem with the rom but with my hardware. Should I try flashing the latest radio?
Does anyone else here have this problem? Wtf is going on?

idk if its the same problem you're having but mine has recently started turning the screen off, the buttons still turn on as well as the led blinking if i have a notification but the screen wont come back on until i do a battery pull
so i'm also wondering what the problem is, fyi i'm using the kernel that came with cm7 and the latest radio

Hmm not sure. When my screen wont turn on I get no lights at all.

One of the causes can be the battery going bad.
I had the same issue until they sent me a new battery.

I have tried many different batteries with no effect.
I have noticed however that if it goes unresponsive and I plug it in the charging light comes on and I am able to boot the phone. It will turn off rather quickly though. Like in 20 minutes as opposed to 2 hours. Very weird.

Wow has anyone found a solution for this Problem? I can go into recovery and flash roms with no problem but as soon as it boots to the home screen its just automatically shuts off. Only twice have I gotten it to actually stay on for an hour or so. Also while charging it flashes green then orange, I have two different batteries, any ideas?

Well mine is the same it started after a small six to eight inch drop on the floor and it randomly freezes and when i boot it up just goes into boot loader and after a while of it being off it will go into OS any ideas anybody I am thinking it has something to do with bad chip but what do i know lol tel me know if anybody finds anything out thanks in advance

I've begun encountering the same problem after flashing MIUI 2.3.30 ROM. And I've also noticed that my phone started to get hot. It never did this before. I know my battery is fine, I also re-calibrated my battery and everything. I am even also thinking that for some reason my phone is bricked. It holds charge for about 10 minutes before it dies, even on the new battery, which I have tested on another MT4G and works perfectly. The other phone is my nephews. I wonder if this has to do anything with the bad EMMC chip?
Any input for solving this will greatly help.

You might have already looked at this but have seen in some other roms I have been working with is to make sure to check the md5 sum before flashing just because it flashed doesent
mean it was right it takes is slight hickup in a download and a bit of garbage where it don't belong. Better to check it do the full wipes even a couple times or maybe even mounting and format the boot n system partitions so if on a particular rom ask in its section.
Hope that helps, wish ya well

I would agree with the above post making a clean wipe, and even the format does help. I have been trying out almost all of the newest ICS roms avaliable and I notice it helps when wiping everything/format system and boot. Even the newer ICS rom Awesomev2.1 suggest doing so for the system partition.

As others have stated, you might not have performed a FULL wipe.
Reflash, but do the wipe (I did also wipe battery stats..seemed to help in my case)

Random restarts and won't load
Had the same issue when I switched to Virtuous Unity... battery wouldn't hold a charge and would randomly restart.
After basically nuking my phone (full wipe, cache/battery wipes, etc.), as well as installing Creamed Glacier, the battery life is better but the random restarts are not. Plugging the phone in is the only way to keep it from restarting constantly, where it will load the T-Mobile splash screen but turn off either immediately after or as the home screen loads. But the battery is always at least 50% when I plug it in and it stays on. It also seems to take forever to recharge (plugged into laptop).
I want to think it's a battery issue, but the fact that it's not dead when I plug it in makes me think it's a hardware issue. I can't send it in to T-Mobile (shipping charges and time would be huge, as I'm in a foreign country and I rely on it so much for communication), and I'm loathe to buy a new phone.
Anyone have any ideas?

I really hate to be redundant, but you formatted /system and data? System gets missed a lot and you didn't specifically mention it.
Sent from my HTC Glacier using XDA

I have had the same problem with ics zips 4.01 all of a sudden the phone stops responding to the power button and have to take out the battery and boot up the phone but as of yesterday with the 4.02 I have had the problem. I don't know if it due to the heat cause where I live it hot and its just the beginning of summer too?

vibrant won't stay on

I've been on Passion since it dropped with no problem, but it shut off today and wouldn't stay on like a dead battery. I charged and the problem persisted so I odined to stock, flashed bionix but it still does the same thing. It usually doesn't get past the vibrant screen but will stay on for sometimes a couple of minutes at most. Any ideas?

Factory Reset, format sdcard, and reflash your Rom of Choice

help please
The first time I odined it stayed on long enough to set the phone up, the second time I odined I tried the factory reset afterwards, also did not work. Out of a dozen times of
powering up, it will only make it past the vibrant screen once, then it shuts off with no vibration. After it turns on the first time after Odin, it won't turn back on until I Odin again. It won't go into recovery by 3 button, but the power menu works on the occasion it stays on long enough. It even powered down while in recovery. It stays on indefinitely in download mode and goes right into download mode

Sounds like hardware. Can a battery be so bad it kills phone even on external power? I would look at battery contacts and the battery itself. They are pretty cheap on ebay.

Pretty sure it is an internal issue, it looks like an exhibit for me until May upgrade. Tried everything I know to do and it won't pass odin now, fails on factory rfs

If it is constantly powering down even while charging, it sounds like hardware. You might send it to the Unbrickable Mod guy.

[Q] S4 won't turn on, looks dead

Hi.
So, yesterday evening I plugged in my Galaxy S4 I9505 (international, and running stock Android 4.2.2) since it had low battery, then set the alarm clock and went to bed. Today I woke up, checked my clock (not the phone's, my actual clock), and since it was earlier than when my alarm would ring I took the phone to check my emails a bit... only to find out that the phone was stuck on the lockscreen and was not responding to anything. Perplexed, I took the battery off, put it back on, switched the phone on and it seemed to work fine, only to freeze again after a few minutes. I took once again the battery off, put it back on, and this time it didn't turn on at all. I tried several times, tried also while charging, but it doesn't even seem to charge, the led is completely dead. I tried to boot into recovery, nothing. Once or twice when I tried to turn it on it would show on the upper part of the screen an extremely fast and small red text, like the ones you see in recovery but red instead of green, but it was so fast in appearing ad disappearing that I didn't even have time to read it.
Then I tried googling the problem, and of all the different methods only one seemed to work: take off the battery for 10 seconds, put it back on, press volume down + power + home. Which I did try before, but without waiting before putting in the battery again. I tried it this time with the 10 seconds of waiting (while not plugged in to the charger), and it worked. The screen asked if I wanted to flash a CR or just restart. I choose restart. The phone immediately died again and didn't turn on, not even with the method that worked a few seconds before.
I haven't been able to turn it on since then, and I've tried everything. I'm quite desperate, because I have AADD and I do everything with my phone, it's my lifesaver and the only thing with which I'm able to organize and remember stuff (including my daily meds). Also the only thing I never forget to bring with me. I literally can't stay more than a full week without it, is there anything I can do or try to make it work again?

Is there really no one who can help me?

mate try to use a charged battery from anther s4 switch it on

Took a picture with flashlight on, now hard bricked

this could have just been bad luck but now it looks like im sending my phone back to huawei AGAIN.
Long story short, i JUST got the phone back from getting a battery replacement a week ago and every thing was great. Finally could go from 100%-0 with no issues. I was looking for a serial number on a router and with the flashlight turned on i went to take a picture. Screen froze and started to boot loop. I did manage to get back into TWRP after the first boot so i decided id wipe everything and restore my Rom seeing as i had just backed up yesterday and wouldn't miss much. It got me to the "please lock your bootloader bla bla bla" screen and went black. No google screen or anything. Now its just dead. plugged it into a charger. Nothing. Plugged it into the computer. Nothing. Hold down power for 20 seconds. Nothing. Hold volume down and power. Noooppee.
So yea, either im an idiot for trying to take a pic with the flashlight on or im having a bad run with this phone lately. Maybe both. idk. i love this phone but this is getting ridiculous.

I've taken pics with the flashlight on several times on mm and nougat. I've never had any issues from it. If you can still get into TWRP maybe try to load factory image. If you aren't even getting to to google splash screen it's almost like you don't have an os installed.
Nevermind. Just reread what you wrote and saw that it won't boot at all.

I'm having the battery drain issue with my 6P. Google said they will send an RMA even though I'm out of warranty. I've just got to tell them to send it. Haven't done it yet because I'm halfway scared of getting a device that has worse problems. At least now I know 15% battery actually means 0. Other than that it's in perfect condition. After your experience I may just keep my phone and try replacing the battery myself.

its funny because i bought directly from huawei in November of 2016 and before i sent it in it told me i was under warranty until Jan 26 2017. now i just checked and im under warrenty until 4-3-17. so maybe they dont even trust their own work and extended my warranty lol
if i didnt have a back up phone id be way more pissed off about this.

There is another thread where ppl are able to regain access the dead phone by holding the power button down for an extended time. Some say a minute and a half, others several minutes but their phones were coming back on and fully functioning afterwards. If you can get back into recovery why not try a factory reset before restoring your backup.

Some people have reported that plugging the phone into a wall outlet for an extended period of time (sometimes 24 hours or more) brings the red notification light back and then you can power on again

Droid Turbo 2 Sudden Shutdown + Boot loop

TLDR: are there any diagnostics I can do to verify that my battery needs to be replaced?
A few days ago, I turned on my phone to check the time and a half-second later it suddenly and instantly shutdown. I was not able to restart it at all. When I got home and plugged it in, it began a continuous boot loop, with only the motorola splash screen displaying, then nothing for a few seconds, then back to the splash screen over and over.
Fortunately, I was able to get to the"AP Fastboot Flash Mode" menu. I couldn't do anything from there on the phone itself though; every option just went into the boot loop again. I was able to get a fastboot connection with my PC and so reflashed the phone successfully.
After reflashing, it went into the boot loop again. I began looking for more solutions online and wasn't paying attention, but sometime in the next 5-10 minutes it made it to the login screen! I re-set up my phone and all seemed to be working fine!
Until the next day. I tapped an app and instead of opening, the phone immediately shutdown and went dead again. Took it home, plugged in, and it went into the boot loop again.
Anyway, I've read a few threads on here and elsewhere that the culprit may be the battery. I would like to have more than just a hunch before I shell out the money and time to replace the battery -- is there any way I can verify that the battery is indeed the problem? I didn't seem to be having any battery problems before - charging and usage seemed fine. I did drop the phone rather hard a few weeks ago, but didn't seem to effect anything (short term at least).
Also, could using a non-Droid Turbo 2 charger affect battery life? I actually got the phone used and didn't get the official charger with it, so I've been using just a random leftover one for ~6 months.
TIA!

Try the apps such as Ampere which shows battery info.
I don't think so Non-Turbo charger can lead to affect the battery life but using a cheap charger does.
