My Google Nexus 4 which was working without issue suddenly began stopping at random times. After few boot ups OS didn't bootup where I had to factory reset wipe from recovery mode. But suddon stopping issue still persisted. Soon it came to a situation where factory reset could n't recover at which case I tried installing Synagenmode. I could not install Synagenmode for some reason. There after I flash factory Nexus 4 ROM again. Still the sudden stopping issue exist when phone is discoonected from charging cable. Phone works fine when connected with main power.
The battery is not empty though it stopped suddenly, I am saying this because I can boot it up again though it stops again before fully bootup. Is this a hardware failure or software faikure such as battery cache

When you say your phone is stopping, do you mean it turns itself off, or just freezes? When you said you flashed factory ROM, do you mean a factory reset, a zip or a factory image via fastboot?

Yes it turn itself off.
First I factory reset via recovery mode
Then I flash factory ROM via fastboot as mentioned in "[GUIDE] Nexus 4 - Factory Image Restore" of androidcentral dot com

Try using a Qi Wireless charger and see if it does the same thing. It could be that your battery has shot craps and while it has a charge, it is not producing enough mAh/voltage and the phone is turning off believing the battery to be dead. I used to have a similar with a Samsung handset which had a removable battery. I would be at 90%+ and it would just shut off. Every time, the battery was swollen and beginning to fail.
You can see how the system is reading the battery status from a logcat. It might give you some insight into the root cause.

My Nexus 7 was working fine until one day it was stuck on google logo and kept restarting itself.
After contacting the help team at Nexus, I was advised to wipe all data and perform a factory reset from the recovery mode.
The device worked fine and I started using it again,but it broke down 4 hours after the factory reset.
I was putting music on it via usb and all of a sudden it turned off.
when I press power it shows google logo then goes automatically into recovery mode, I have tried to factory reset again and restart but nothing worked !
Any help is greatly appreciated , thank you

Try flashing the stock rom again, then see what happens.

Download wugstool kit (Search development thread) ...connect your n7 with pc.. and flash Stock Rom
My Nexus 7 has been freezing on me lately, so I figured I should back it up. During the backup it froze at 60%. After a reboot I attempted to backup the most important data but titanium backup kept failing. After two failed attempts the tablet powered off by itself. It would not boot past the Google logo. I was able to get to fastboot mode. While in recovery I did a factory reset. After the factory reset the Nexus went in to a boot loop. It displayed the Google logo, then reset. I could still get in to fastboot mode and it froze once more while in fast boot mode. I powered it off and now it does not power up. The battery showed 43% when I was doing the backups, but I thought it might of been wrong so I recharged it for two hours. It still will not boot up. If I have the Nexus plugged in to my computer and turn it on I can hear the sound that a new device is connected but almost immediately the sound for the device being disconnected plays. I figure the flash memory has failed while writing to it during the backup, but the new device sound seems odd. It is under warranty and I will probably have to RMA it. But before I that happens I wanted to check with awesome xda community and see what you think.
Has anyone experienced this before? Any idea what went wrong?
Thank you for reading my post.
Hello guys, i'm having a problem ;f
I was on cm12 nightly when i decided to reboot my device after few days of running, strange thing happend and i ended up in bootloop.
I've downloaded 4.4.2/4.4.4/5.0.1 stock images and tried to flash it guided by the instructions in this thread, however i still get a bootloop, even after clean installation, even after wiping cache and doing a factory reset.. I've managed to boot up my device twice since yesterday, after getting stock image to work i pushed cm12 and gapps on my phone and flashed them.
At the first try, i got bootloop again, so i decided to go through the whole process again, many attempts later i've managed to boot up my device again, and again i decided to flash cm12 and gapps, this time my device booted up properly so i wanted to gain root access, in order to do so I flashed UPDATE-SuperSU.zip file and as a result end up in bootloop again.. I have no idea wtf is wrong with my nexus. I am still trying to flash factory image, and i always end up with bootloop.. I'm out of ideas here, HALP! ;(
@update:
I have uninstalled all drivers, and mount my device to another usb port, then with NRT i installed google's drivers, by using nrt i have flashed 5.0.1 factory image, rebooted into recovery and wiped/factory reset, after that i rebooted my device and still no luck - hanging on floating dots for 15 minutes..
Before all of this I tried formatting my cache to FAT and to sdf4 and it didn't help, I literally tried every single instruction i could've found ;/
What's wired is that when i encountered bootloop yesterday and wiped/factory reset i booted fine, after restart it went into bootloop again, so i thought i would wipe/factory reset again i'll be good to go, but.. it didn't help this time oO
things i've already performed:
1. fastboot oem lock/unlock
2. wipe data/cache/factory reset
3. flash factory images of 4.4.2/4.4.4/5.0.2 through NRT/manually
4. converting partition to fat and next to sdf4
5. reinstalling drivers
6. different ports and usb cords
6. i even tried switching motherboard from my old n4 and i still stuck at bootloop *LOL!?*
7. after 6 i thought it may be related to usb port so i switched usb port from my old n4 and it did help but.. until next reboot ;/
from time to time, after flashing it boots up just to make my hopes and then it gets the bootloop after restart ;/
@update2:
It seems it's hardware related issue. I have tearn down my nexus device and left only motherboard with fron/back cameras and audio jack, daughterboard, i even disattached the speaker along with antena. At this point i flashed factory 5.0.1 and it works, i'm in the moment when i plug peace after peace and turn on the device to check if it still works. I'll update when i find out what was the cause of the problem.
@update3
Stupid as it sounds the issue was caused by the vibrator module, while it was disattached, the device was booting up without any problem.
Hi All,
I am having a similar kind of problem like many others already stated but mine one is a bit unique.
My phone will power on, google logo appears, it starts to boot then nothing happens....it keeps on restarting the sequence but never completes the boot process. I can access fastboot, recovery mode but the phone itself doesn't start.
However if I keep it plugged to my wall charger it completes the boot process and I can access my phone, but if I unplug and start using it just shuts down randomly (1 min-30 min).
I have wiped cache, restored to factory already. Currently I am running 5.1.1 with no modification at all.
Any suggestion to bring it back to life is appreciated.
Replace the battery and I think it will work without any issues.
Nitin
Most likely the battery is dead.

So basically this rom is awesome but it had only one problem. When I plugged my phone in the charger while it was turned off, it bootlooped until I restarted with the cable off. It was no big deal and nothing bad ever came out of it.
Yesterday my batter ran out while I was asleep and when I woke up it was already turned off. I, absentmindly, tried to turn it on, LG Logo, off again. Did it one more time, nothing happened, realized it's out of battery. Plugged in charger, try to turn it off/on, usual bootloop happens. Say ok and proceed with what I always did, phone gets past LG Logo, goes into SlimLP boot animation and for the first it has just stayed there. No restarts, just endless loading. Longest i Left it on to load was about 45 minutes. Never got back on.
Apart from that, I think that for some reason my recovery got uninstalled somehow, by itself, a few weeks ago. I only noticed this because before, when I wanted to get into recovery, I pressed the usual buttons and it went straight into TWRP. Now the same buttons take me to the "Factory reset screen". I know that everyone says to just go ahead and press power, but I am afraid, since I am not sure if TWRP is still functioning. This happened to me another time on the same phone, and when I confirmed the factory reset, it factory resetted.
My problem here is that I want to get my music and photos. I'm only able to enter that factory reset screen and download mode. Can I "flash" twrp safely from download mode? Should I use Flash Tool 2014 and Normal flash(which says it keeps the data) a stock g2 rom? Can I mount my phone to the computer in download mode to copy my files? I want the most risk-free approach.
Thanks in advance.

Hi, first If you can enter download mode I think you can flash kdz (Kitkat) file to stock using Flash Tool 2014. But I had this problem once and the keep data flashing didn't work (stucked at 50%), I ended up flashed it with other option (erased all data).
2. You can try the "Factory reset" nice and easy.
I think you can't see files on the device unless you enter Twrp.
It's wise to backup your phone on the computer montly or so, thank you.
I went ahead and nuked my download mode using the SRK tools. Then got access to fastboot, through which I booted to twrp and then I could move my files. All's fine, flashed my ROM again and it's going better than ever.
