So, last night I was out and about - just having a good time. Noticed that the battery on my GSM Galaxy Nexus was getting low. Went "Meh, wasn't the first time it's died." It got to 1% battery power and shut-off, like it normally does. Me being who I am, I turned it back on to see just how much more juice I could get out of it.
Phone booted up alright. Finished the boot animation, and then a couple seconds later turned off.. not a big deal. I get home, plug it in, and the charge screens cycle..... and then they cycle again. And again. And again. Basically just looping. I turn the phone ON, finishes the boot animation and... turns off again riight away? Goes back to the charge screen loop.
I'm not talking about the regular charge screen. After the battery gets 'filled' twice, it completely restarts. Black screen for 2 or so seconds, and then it goes through the charge animations as it would if you had just pluggied it in. I CAN get into bootloader, but that's about it. I'm just curious.. has anyone seen this before? Or know what my problem might be?
I'm unable to turn USB Debugging on in the system settings, so I'm at a loss as to how I can fix this issue WITHOUT bringing it into Bell.
Try going into recovery and wiping cache and dalvik. If that doesn't work reflash your rom
My phone is completely stock (I reflashed it to to the stock yakju? I believe it was when I found out Samsung had screwed people off the google update path.. so I can't get into recovery mode. It just shows the broken android. It's all been re-locked, and since then, my laptop has died. So I no longer have the ABD/Samsung drivers setup. Which was a pain to get going the first time..

The "Broken android" IS stock recovery. I believe that when you push Volume Up seeing that image it takes you to the stock recovery menu. But you can always reflash Yakju or any other ROM through fastboot mode (see the tutorials here on the forum).

Turn it off. Leave it charging for a few hours before turning it on.

You do not need to have USB debugging enabled to use fastboot.

It doesn't take long at all to install the drivers. Look for a thread with "universal" in the title. I think it is in GN General. Once you do install the fastboot driver, download the fastboot.exe file and reflash the stock ROM.

The problem I have is that the charge animation doesn't change... i.e. It'll constantly refill the battery and all, but it always starts from the bottom (While when a phone is say... half charged, the little battery is half filled and the animation continues.
I'm not sure it's even charging at all.
Update time!
Got it into the stock recovery. Wiped the cache and all of my data. Rebooted, and.... it turns on! No longer reboots on regular startup. That's the good news. So at least it's somewhat useable now..
Now for the BAD news.
-It still does that retarded charging bootloop that doesn't seem to get me anywhere
-....When it's on. Like, running, it doesn't charge. Nadda. Zip. Zilch. Computer, wall charger, android dock, nothing. It just won't charge when it's on. However when I got it to power on, it said I had 14% remaining - which means it was likely charging inside the Bootloader, as I had it on that for quite a bit.
I think this just went from a software to a hardware issue. Thoughts?

Power down phone, do a long battery pull, place it inside again, let it charge for a few hours without powering it on, when it is fully charged (or after a few hours) pull battery again and then take charger out the phone. After a few minutes, place battery inside phone again and start it up without the charger.
Hope that works.

And that might fix this charging bootloop? Because the LCD doesn't even turn off..

+1 for the new battery thought.
Battery test
I am having a similar problem, I get the boot loop.
Difference is that I had started with a new battery so that could be your problem or unrelated. I went to a mobile shop yesterday and they let me use a new battery to see if the loop would start. It did not so there seems to be at least one other failure path. I have avoided a factory reset as I was hoping to pull some pictures but coming to the realization that I will have to try factory reset as a last resort
I posted to this thread #192
http://forum.xda-developers.com/showthread.php?t=1490815
My Galaxy Nexus phone from WIND went into a reboot loop yesterday. It had been charged to 98%, used to make a call and then put away. Wireless was enabled. Noticed vibration periodically and say it was rebooting every 6 - 7 seconds. Pulled battery to stop reboot. Saw references to fully charged battery via USB stops reboot loop so tried that. Battery voltage was 4.17V and still went into reboot loop.
Tried to boot into safe mode but still goes into a loop
I went into recovery mode and tried all options but factory reset because I am hoping to recover some pictures
reboot system now
apply update from cache (but did not have an update to install as only options were ../ lost+found/ recovery and when I selected these was in a loop as well)
wipe cache partition
Can't tell what version of Andorid I have as the phone never finishes booting.
Boot console gives the following information
Product Name – tuna
Variant – maguro
HW version – 9
Bootloader version – PRIMEKK14
Baseband version – I9250UGKL1
Have installed SMS backup because I was planning to do a backup after a trip. Also have two GPS tracker apps installed.

If you can boot into recovery, you may be able to get your pictures off your device.
1) Make sure you have the drivers for your device properly installed on your computer.
2) Download the attachment and unzip it to a directory on your computer.
3) Open a command prompt in the same directory.
4) Reboot your device into recovery and plug into your computer.
5) Make sure your computer sees your device by typing: adb devices
6) Pull the data off your device by typing: adb pull /data/media
Note: depending on how much data you had on /sdcard, this could take a while, so be patient.
usual story.
got an htc one x. flashed unlocked all going well. installed a bad rom (did not make a back up)
froze at splash screen. only late last night i found disaster recovery, so i put it to download and shut off the phone. boot back up this evening and tried to install recovery re-lock bootloader, clear cashe etc but. i got a low battery warning when trying to flash.
i didn't have the latest clockwork mod for charging installed; and battery is too low to flash to it.
this is where things get different. i used the boot loader to power down. i plugged it in to the wall to charge and i got this strange flashing red led(not orange) after about an hour it went solid red. had it charging from the wall socket for well over 4 hours now with the solid red led.
then all of a sudden the led starts to flash red again. so i disconnect the phone and try to boot.... nothing happens. try bootloader mode(power + vol.dwn) nothing.
i had to hold the two buttons then plug in the wall charger. then it went into bootloader. problem is it says relocked AND security warning....... and still after all that time charging. i still get low battery warning @ flash.
so i tried to turn off the device again using the power down option. two things happen here. 1)if the charger is in the screen goes black and instantly restarts to fastboot usb menu. 2)if it isnt in it will turn off and wont turn back on (splash screen or bootloader) until the charger is back in.
so what ive done as of now is plug it in to charge over night and hope this thread can shed some light.
additional info:
ruu version: 'RUU_ENDEAVOR_U_ICS_40_hTC_Asia_WWE_1.28.707.10_Radio_1.1204.103.14_release_257076_signed.exe
os version: 1.28.707.10
clockwork mod version: 5.8.2.7
plz any help would be invaluable
EDIT: just turned on phone about ten minutes after i plugged it back in to the charger (held power button alone) splash screen is back (yay!!) but still battery low when trying to flash in
fastboot usb. ima try in the morning after a full night to the charger. fingers crossed

srry posted last night but would not show the thread... so i figured i couldn't so i tried to post in an existing thread. now i dont know how to delete that other one...
FIXED
well never mind the fact that i loaded a plethora of info onto this post and nothing.
but besides that i got it working. in the disaster recovery tut it only lists using the ruu through a flash... never stating that you can just run the file directly and not go in %temp% and get the rom.zip(excepting for the recovery_signed.img). simply find your version of the ruu that you need, flash back to the stock recovery image (within the rom.zip) relock bootloader place device in fastboot and run from pc.
the only hard part is getting it to charge... dont know how mines took charge but i pluged it into the sockets @ my school (long story read this thread: http://forum.xda-developers.com/showpost.php?p=26156147&postcount=20).
when i pluged it in the light went solid red instantly no blinking. after about an hour of charge i pressed the power button and it went to the splash screen (still was on a older CWM which doesn't support charging) left it at the splash screen for the remainder of the class (about another hour) unplugged entered bootloader.
@ this point i had no security warning under relocked. but i used the power down option, took it home and tried to unlock/flash to the latest version of CWM so i could charge. it worked without a hinge.
anyone know why it took charge on an older CWM?
note i got the phone back up and running and the first thing i did was make a nandroid back up
hi i dont have an answer to your question but i have a question to your answer am curently suffering the same problem i can flash the stock cwm because of low battery, and i know when in boot mode it doesnt charge so i rebooted the phone it took me to the htc logo and its displaying a solid red light does this mean its charging or what (the boot loader is re-locked so i can flash stock cwm but cant due to low charge)
Noob badly. But I think it should be charging. Could b wrong. Leave it there for a couple of hours and try again. Mayb fixed. Give it time and try again.
Sent from my HTC One X using XDA
Same thing is happening to my phone. and its bootloader is locked and cannot be unlocked because of the charging. its usb debugging wasnt turned on either before it went down.
Please help anyone?
Guys I have Htc One X. I rooted it then I thought to install a custom rom (resurrection remix) and gapps. so when I was in the CWM recovery I installed the mod while it was installing it said error no file contents but it installed successfully anyway. after that I installed Gapps but it got an error and said Installation aborted. I then started panicking and I tried to restore the backup but nothing happened, then I re-locked the bootloader with battery below 30% then I used the batch file to charge it then I unlocked it again. Now I want to download a stock rom I tried 2 one was a newer version than what my phone actually is and the other one was a lower version than what my phone actually is. I then tried alooooooooooot to search for the appropriate one for my phone but I didn't find it so I thought to continue with installing custom rom anyway but the problem is that I need to get the new mod zip file and new gapps zip file into my phones sdcard but I can't do that/I don't know how. My phone isn't recognized by my pc ( I can't browse it's files) and I tried using adb in command prompt which is very complicated for me however I searched on the internet and tried to do the same but then it says "adb server is out of date killing" then I found one adbFix.exe that said that the adb in HTC sync manager folder is causing a conflict but then the Fix file said that its ok and no problems are there. Now I need to put custom rom and gapps zip files to my phone's sdcard but I can't. Please I would be very grateful to anyone who would help me and guide me and If I'm posting in the wrong forum or thread then please forgive me for this is my first time I made an account on XDA and my first ever comment/
First off, S-off phone
So, I've been running the GPE rom posted by Joel for a while now with no issues... Today a friend wanted to see the phone, so I pulled it out of my pocket; hit power; nadda...
So I held power down for a while; got teh HTC screen; then nadda.
So we then attempted to get into recovery, power + vol down then selected recovery... Nadda, just a black screen.
I then redownloaded TWRP and fastboot flash recovery recoveryname.img, it tries to push it then it'll throw an error saying: "remote: image update error"
I looked around and found a thread with full directions with an RUU.. So I tried doing that, hwoever after clearing the cache via fastboot, when I try to do fastboot oem rebootRUU nothing happens.... sometimes teh screen goes blank, sometimes not.
Anything else I can try? I'm really wondering if it isn't defective hardware... .only had it 2 weeks too...
You are sure the phone is fully charged right ?

i was going to say the same thing. not sure how but i sometimes pull the phone out of my pocket with the screen on... so who knows which programs could have been tapped and running if it's bumping around in your pocket.
This is one of the reasons Verizon requires locked bootloaders now on all their phones. If the phone isn't even turning on, your first step should never be to try flashing a custom recovery or RUU (?!). If the phone has no charge and dies in the process, you could potentially brick it for good.
Sorry if that came across harsh, but... honestly, try charging your phone overnight first.

Guess I should have put more details in the first post... when I got it into TWRP the first time it showed an 88% charge. I attempted to restore a backup and inside the recovery it would say it failed reading the memory and then it couldn't browse anything.
If I attempted to simply factory reset inside the recovery it would just lock up. If I tried to flash a rom via zip, it would lock up...
After a few times of rebooting it into the recovery I couldn't even click anything inside it without locking up.
it was at that point I tried to flash a different recovery and started getting the errors...
Anyways, more I researched it simply was a bad phone with defective hardware.
all good...
OK all I am sincerely reaching out as I am out of ideas. Here is the situation...
Issue : Last evening, running most recent Liquid Smooth 4.4 (Superb ROM, I don't feel this is really at fault just relevant and thorough), I had been doing some heavy tethering when I picked up my beast and stepped out for a smoke. As I am reading up on moto360's 2 1/2 hour sellout I get a random reboot. Eh, no biggy ... it does happen. (Not often, or at all to speak of in my case just stating.) Right after reboot I hit the power button to make a forced boot cycle and it rebooted again before I pressed anything on screen!
Now SOMETIMES I will boot past the initial "NOTE II" splash (NOT often at all ... usually get reboots, splash hangs, or the phone simply turns off on its own from here) If it does make it past Note II splash it will reboot, hang, or simply turn off from here as well.
Steps Taken: I firstly, attempted a restore... no dice. I attempted a fresh install (TW, SlimRom, and DU) ... no dice dos. OK hmmmm
Now to all mighty ODIN (L900VPUCNE2_L900SPTCNE2_1561791_REV04) .... NO FREAKING DICE!!! WTF?!?!? I additionally attempted MC2_STOCK_with_COUNT_RESET-20130511 ... no bueno!
I still have access to Recovery and Download soooooooo ... I lay down at the mercy of you the community!!!
Thanks in advance and if you need more info PLEASE don't be shy!
Same issue here!!!
After a random reboot, I have the same type issue!
Running an almost stock NE2 rom, random reboot then hanging at the Note2 bootscreen.
Like you, I can access download and PhilZ recovery.
I CANNOT flash through recovery. Errors out.
Odin flashes succeed but on reboot I still hang at the Note2 bootscreen.
My recovery is showing multiple error related to accessing E:, E:/cache, etc.
Are you having that issue as well??
Try this go to samsung-updates.com
search device l900 scroll to the very bottom of the list
download the L900VPUCNE2 zip (this is a pure sprint rom)
flash using ODIN3 v3.09
I have flashed this file many times and it works every time.
Hope this Helps.
Exact same thing
I've been running the latest nightlies of OmniRom. And yesterday, out of the blue, random reset then bootloop. No luck with anything, recovery, odin, etc.
Did Sprint deliberately brick our phones?
I'll try the odin to stock to see if I get any luck there. But if anyone else figures it out, it'd be nice to know the fix. Thanks!
No luck going back to stock. It's dead Jim.
I had a very similar issue. Try booting your phone with it plugged into the wall changer; something given the full 2amps of power. It it'll boot, it's possible your battery is bad.
If my case, my phone would boot loop around the splash screen. on the battery power only. I could go into recovery and download mode with no issues and stay on for hours. If I connected it to, say a PC, it would boot, but would random shut off within five minutes. But if I plugged into the wall charger, it would boot with no problems. Stay on for hours. If I plugged it from the charger, it would immediately shut off and try rebooting which it would just boot loop.
Luckily, the batteries are pretty cheap at $10 to $20 on Amazon. I went with the Anker for $15 to get me by till I get my next phone, which will probably be October; I'm heavily learning towards the Note 4
Replace the battery
I had the exact same issues. I ended up buying a $10 battery on amazon and it solved the problem. I did go through all the flashing, odin to stock, etc. All was pretty good when plugged in to a good power source. It took me about 4 hours of trial, error, reflashing, etc before I realized it was probably a battery issue. The new battery has solved the problem.

I couldn't flash any of counter reset rom through anything but TWP so i have to boot into download and update away from Philz. AFTER the recovery update I started making headway. but couldn't ever seem to make it past boot no matter how much batter is charged. I was beginning to think it was something that died on the inside (heh...heh)
After reading through some of these greatly appreciated replies I am going to plug her up to the wall and try the ne2 counter reset again(12:58 am). ... AND I may go throw some cash at a battery juuuuuust in case. (I do tether 100gigs daily sooooooo it does make sense that it could have burnted up lmao!)
UPDATE 1:25AM : I did as advised and it does seem battery has taken a dive! hmmm so weird! It still shows having power and charging. But after being plugged into wall I made it booted into a fresh ODIN install!!! (keep in mind that AS SOON AS odin gave me a pass I switched to Wall outlet!) I have even performed a power cycle to confirm it wasn't a fluke! I will indeed be out first thing in the morn to get a new battery!
AGAIN I can not thank you all enough ... I would have never thought of that. (you would think it would be one of the first things but eh you live and learn.)
I will update with any new progress!
cheers!

Mine does the same and hangs .... right? HIt the power button and as soon as it lights up to start to boot then plug in the power cable. (the freezing while off and charging is a known bug in at least two roms i believe)
Congrats Rubledub!
As for me, I'm still screwed. Invested $40 in a battery (had to have it today, couldn't wait on shipping)
With the new battery fully charged I still have the same result!

There were probably signs of the battery going bad, but misread. But in my experience, it went to total crap instantly.
The signs of going bad were shorter battery life, getting stuck/freezing when trying to charge the phone when off (there's that battery graphic that shows up). Unfortunately, I did all kids of other stuff before I really figured it out, and looks like a messed up my modem and now cannot connect to 3G. Kind of irritating, but luckily, I spend 75% of my time in LTE areas. Just got to ride this out till the Note 4 is released.
Here is thread of when I was having trouble: linky/URL]. It's a lot of me trying slightly different things with no changes in results. Plus, I was a buddy's house who was in a 3G only area. The worse part, my phone did this the day before I left to spend the weekend five hundred miles away from home at a friend's house to visit.

Weird Recovery Lag and bootlooping after CM12 update
Hey guys,
I came across this thread and the issues I'm having sound so what similar, so I thought you might be able to help.
I have two Samsung Note 2(l900) and running on cm12 as of yesterday morning. I installed the new nightly manually on both devices the same exact way by opening clockwork recovery and installing zip. One device was successful and is working just fine, the other seemed to flash fine until it had finished loading the apps and going into boot. The device would restart on the note 2 logo screen and then proceed to the cm12 boot screen and then restart after a few seconds. I went back into recovery which took longer than usual, and proceeded to clear partition, wipe dalvik cache, and install older nightlies. I had the same result no matter what nightly I went with.
I decided to set the device back to stock rom and root again. I it worked just fine, so I went through the process about 4 times installing different nightlies but had the same restarting results. It was then I noticed that getting in clockwork recovery manually lagged about 30 seconds. I took the advice of someone on the Google plus forum and switched the recovery from clockwork to twrp. Tried again with the same restarting results and with the manual recovery lagging about 30 seconds to get into.
I'm back on stock rom and the device is working great but takes forever to get into manual recovery which I believe is why it is having issues booting Cm 12
I know flashing roms are easy. But it might be difficult for newcomers like me. I have always a question in mind what'll happen if my phone shut down due to low battery in fastboot/recovery. If I format the OS before shutdown, is it possible to charge the phone offline without no OS then continue flashing roms?
##Following things happened with me.
I was in MIUI 12.5. I installed Pixel Recovery to flash PE12 via adb sideload. Then I cleared all data/cache. When I tried to update the rom by sideload, it didn't work. I wanted to search the internet and as it would take time, I tried to turn the phone off. I couldn't even shut the phone to save battery. Whenever I pressed power button, instead of shutting down, it always took me to the bootloader menu. Thats when I thought about this question.
that question is so out of the box, i doubt anyone can give you an answer with proof
but yes, i believe it is possible to charge even without OS and no, i dont have any proof to back this up
That's why you need to charge phone first at least until 50% up before flashing any rom.. otherwise if still happen phone shutdown while flashing, yes you still can recover as long your phone bootloader still at unlocked stats also phone still can go into fastboot
If it shuts down when in fastboot/recovery because the battery is empty, you simply charge it and reboot, that should cause no harm. Shutting down while flashing a ROM however is a totally different story. You might get lucky and be able to boot the phone back into fastboot/recovery or you could end up with a paperweight.

I did shutdown the phone within fastboot to cancel flash all and lock....then booted in forced fastboot end flashed with flash all to not lock the bootloader....and had no prob....! I think those partitions are protected against those scenarios....

No. NO NO NO and NO.
You were lucky. This can totally brick your phone. Critical partitions are being modified in the Flashing-process.
There is no protection.
If your phone shuts down during the Flashing-process, your phone can get bricked (black screen) and you can't even boot Fastboot & Recovery anymore. I know this. I have experience.
You must ensure that you have enough Battery (I recommend 75% Battery at least), that the USB connection is stable (will not disconnect randomly), and that your PC won't crash/shut down.
IF IT HAPPENS, that the Flashing-process errors out, DON'T REBOOT THE PHONE. If you do so, you won't be able to enter Fastboot anymore. You must stay in Fastboot. Just reconnect USB, and try again to Flash. Just don't reboot the phone.
Sorry for fear-mongering, but this is definitely dangerous and not to be taken lightly.

No. NO NO NO and NO.
You were lucky. This can totally brick your phone. Critical partitions are being modified in the Flashing-process.
There is no protection.

I think it is because I forced fastboot mode after few seconds of starting flashing....by the way I was avoid the flash and lock option that I selected by error while I wanted flash and clean...
I think, there is no ptoblem, fastboot Mode is Read Only Memory, no one can write/edit this think.
No matter you abort the flashing prosses , or the device loss power from battery, didn't affect the fastboot sector/bios on PC
