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.

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?
HELP,
yesterday, I was using my nexus 7 for normal use, wasn't playing game, just browsing with chrome. the battery was 8 percent when I last saw it. I then proceed to charge it, but the thing suddenly just shut down itself. I thought I misread the battery percentage, so I charge it anyway. about an hour later, i checked on my nexus 7, turn it on, got to the boot screen, got to the home screen, use it for about 15 minutes, and suddenly, the screen black out, it was flickering like crazy, and making some white noise ish sound. I panicked so I hold down the power button and turn it off. I turn it on again, and after about 30 seconds, the same thing happened again. I was using motley's kernel with 520 GPU, and I thought, maybe my nexus 7 cant handle the GPU OC. So I went to recovery, tried playing with recovery for about a minute or so, but the screen didn't flicker at all on the recovery. So I flashed the 484 GPU version of motley's kernel. When I reboot to system, the same thing happened again. So I thought, maybe if I restore to my old backup, it would not be like this any more. so I wipe the data, dalvik, and cache, and I restore my old backup. But the same thing happened again, only this time, after I turn it off, it make a high pitched sound.
I waited for about 6 hours, and now when I turn my nexus 7 on again, it works normally.
So, what has happened to my nexus 7?

I'd say it is the overclock. Graphic cards do some weird stuff when overclocked. You can burn up your GPU doing that and cause it to forever freak out. I always shied away from GPU overclocks.

It should be ok if you reflash back to stock rom to make all the hardware back to reset mode. A warning always given when we try to flash rom with oc created.
i also experienced this one, also received a battery warning and then suddenly screen went blank. then same weird thing happened as the one above. I'm on paranoid android rom and i'm quite sure it's not overclocked or something. Was only able to get back to normal by holding the power button for around 15-20 seconds...
Happens to me
This will happen to me a lot when my nexus 7s battery dies, I plug the tablet in and then immediately try to start it up. It will work for around 30 seconds then look like an old TV without a signal. I am on stock everything, no rooting or custom Roms (yet). I always thought it had something to do with battery calibration being off and the tablet not having enough power to run, because it always works fine when I charge it before attempting to boot.
I have also noticed that every once in a while the screen will have a vertical line of pixels flicker.
Same thing happened to me yesterday...
I got the "low battery" warning and after some time the screen started flickering in many colors and there was a weird static noise.
I pushed the on/off button, but it wouldn't turn on again. After a few minutes of charging, I could turn it on again.
This isn't normal behaviour, is it? Shouldn't the N7 perform a regular shut-down when the battery has no juice left?
I'm on the rooted stock rom btw.

I faced the same problem. I dont know when the battery might have drained out, but on starting the tab on low battery, it suddenly started showing black screen with little grains and suddenly stopped with a noise. I charged, started the tab again while charging, and the battery reading stuck at 21% even after charging for 20 mins. Within 5 mins, it happened again. Now after 35 mins of charging, I start it again, it boots normal, and now its reading the battery percentage in an incremental value (started with 22%) and now its again stuck at 23%
Is this a HW related issue? Or do you think it is more of SW related issue? If it is more towards the HW side, we better have it replaced. Mine is C70 model.

just happened to me... it may have run out of juice... didn't turn on when I tried, so I guess it did... then I put it on the charger, tried booting it, went away for a sec and when I came back I also got this black screen with some flicker and a static noise...
will now try to charge it over night before trying again...
Nexus 7/Google problems
I received my Nexus 7 on Aug 21 after hearing the rave reviews. It didn't come with app for a camera, so I downloaded one.
The camera didn't work. I re-booted it & it worked this time. Downloaded Skype - whole reason for getting the tablet - to stay in touch with family that is far away. Tried to Skype - camera wouldn't work. Rebooted - worked this time again (getting tired of having to reboot for something I want to use to work). On Sept 2, sent message to Google inquiring about camera & app I downloaded. Only response - "thank you for contacting...blah, blah, blah - check out Q&A." All along, the tablet would shut itself down & reboot randomly (battery fully charged sometimes). On Sept 13, I shut it down & charged it. After a full charge, I tried to power it back on. Tried again several times that night & then the next morning. Called Google (who I bought it from). Told them I didn't want a piece of junk that wouldn't work. He told me it was past my remorse period. (The only remorse I have is buying their piece of crap instead of a reputable one.) I finally did get it to come back on, but camera hasn’t work since even after a complete factory reset. Any way – in order to get this one fixed, I have to “buy” a new one, then send back the old one & be reimbursed. Is this a legitimate business practice?
hi,
since today i have the same issue. did nothing special, just swichting from g currents to chrome. stock rom, no modifications, not rooted, everything original
n7 suddenly had a black screen(battery was at 28%). nothing worked, no powerswitch(10-30 secs). when connected to original power supply and cable, it boots up.. google logo .. glowing X.. lockscreen. then, approx. 30 sec later it turns off again(screen black). usb cable still connected. after some time it comes up again.. and repeats the procedure. after some cycles it stops, and when i reconnect the usb calbe it starts over again. sometimes, before it turns black, it shows a flickering screen and sometimes fizzling sound.
any suggestions?
I had this same issue right after the 4.2 ota update, after leaving it on charge overnight it seems fine now after a couple of discharge / charge cycles
Its like after the update it was over estimating the battery level

Same thing!
I have a completely stock Nexus 7, and the EXACT same problems are happening to me too! The first couple of times it happened my tablet would reboot normaly. But now, my tablet won't boot up at all. Any suggestions on what I should do? Also, remember, I have no mods installed.
Happening to me too.My N7 shut itself down because of low battery a couple hours ago and I haven't been able to get it to boot since. When I plug it into the charger it shows a flickering screen like a tv with no signal but with less white flickers. I've tried multiple chargers and cables but I could only get it to boot up a couple times and both times it did not show that it was charging even though it was plugged in and the battery was at 0% so as soon as it boots up it shuts itself down again because of low battery.
So now I've got it on the charger, screen all a'flicker, waiting for it to get a charge but I've got a feeling its not even charging because, like I said, the few times it has booted it showed the battery at 0% and not charging.
I guess I'll try to leave it alone for a while and see if it will start up after being plugged in for a bit.
EDIT: I let it sit there and charge for about an hour or so (with the screen flickering) and I was finally able to get it booted. It said it only had 3% battery but now it seems to be charging as fast as usual.

Yup... I've let mine sit there turned off and charging over night... helped!
Just had a problem with the Nexus 7 not charging when battery was likely fully depleted. Putting a charge cable in was automatically booting the Nexus 7 up and wouldn't charge shutting down right after. Loops going on and off. What I did was plug a charge cable in and hold power+both volumes and now I believe I am charging at the bootloader screen. It stays on so I will leave it like this and if it doesn't resolve the issue I will try recovery once it is charged.
I've just started having the same issue. Has happened twice when battery gets to 8%, suddenly jumps to 0, shuts down, then after a few seconds restarts itself. Gets to home screen for a few seconds, battery showing 8, then jumps to zero, switches off and has flickering blocks on screen with static noise. This keeps repeating, only way I have found to solve it is to load into bootloader, then select power off. Device charges normally then and once charged works fine. I am unlocked and rooted but running stock 4.2.1, think I'll just have to return it for a warranty claim.
Based on what you experienced, the lesson here is your device can't handle the GPU over clock of more than 446mhz or it will do some crazy stuff.

hi all, today when my nexus 7 left around 15% battery, it showed the warning sign to ask me charge it, so i thought of finish download 1 small apps before charging it. just before i hit the install button, the screen suddenly turn off and whole device was power off.
i tried to on it back (press for 30sec) but no use. so i go and charge it, after trying many times, i finally managed to on it back, but just after few minutes, the screen appear many lines ( just like those old tvs) and it turn off again...then, i tried many times only i managed to on it back.
after that, i continue to leave it there to charge. but after almost 4 hrs( and still counting), the battery only 45%.
wat had happen to my nexus 7? previously i had no such issues, and normally i can fully charge it within 3 hrs. i just got it for 1 week, can anyone tell me what happened? will it damaged my device?
thanks.
no people facing same issue as me?
hey there, im facing the exact same issue and symptoms as you!
the sudden off, the old screen tv effect and shuts down again.
a battery logo appeared though and im leaving it to charge now. strangely it was showing 18%
im running cm10, what about you?
I've had the same issue for first 2 times I charged the Nexus, then it went away. Seems to be battery related, faulty battery?
Same thing happens to me as well. Happened on stock 4.1.2 and happens on stock 4.2 as well. I never try to let it reach below 20%, just to be on the safe side.
Me too!

It happens to me too
Not sure if it's battery related but it happened twice and this is what my battery graph looks like.
Anybody with more info?
I am also on CM10 using setCPU app to control CPU speed when the power is low.
There is one other thread talking about this:
http://forum.xda-developers.com/showthread.php?p=34878700#post34878700
I placed my info there too.
Edit: It's actually happened the last 3 days now ... I'm going to exchange it today.
I get a message "shutting down, low battery" I used to get message telling me to connect to charger. Before I could finish what I was doing now I have no choice. Seems to happen after update 4.3
fix
somehow the battery calibration is out. only fox is to leave it charging for about 20 mins before trying to turn it on. as by then only will the 'x' logo appear. OR if you cant wait popout the back cover, remove/unplug the battery it works. another longer fix is to. turn in back on after it is able to, go to battery settings refresh it, plgg and unplug your charger. the shutdown logo should appear again and when you look to the top, the battery % will revert to its correct amount of 0% try to do this as soon as it is able to be turned on.
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
My phone was acting normal until now. Today after completely draining the battery I went to plug it in at home. The usual battery charging picture appeared and I thought nothing of it. Then when I tried loading the phone, it loaded as normal till it got to the lock screen, where it showed the battery at 0%. If you leave the phone for a while, it goes back to booting and does the Android Animation for a long time before going back to that lock screen, showing 0% and repeating itself. If you try and login, by the time you get in, it will go back to the booting Android Animation.
I can't seam to get beyond this point. I tried turning off the phone completely, then turning it back on. I tried clearing the cache. Nothing. I am stock standard, not unlocked bootloader. I am on Android 8.1.0 Security Patch January 2018.
Any help would be appreciated.
Update:
Just letting you know it is.. 'fixed'. After unplugging the phone and letting it bootloop few times, it finally registered a battery level that wasn't 0%. It was 96% and as such ran like normal again. That being said, I am worried about this happening again, so I hardly think this is fixed, but just leaving this here for anyone else that comes across this problem. Also would love to hear any suggestions to possible fixes. Incase this was related to the other bootloop issues that cropped up last year, I have set my phone for OEM unlocking.
Save yourself the trouble and just unlock your bootloader now.
