My phone goes crazy and start to do random reboots, so I want to reset to the factory default, but then shows a "no command" screen with a dead andy, so I try to flash the factory image from google.
The problem starts when the rebooting of fastboot after opening the bootloader, because the bootloader becomes closed again, so I can't flash anithing.
My device is a Galaxy Nexus GSM yakju with stock Android 4.3
Any help would be grateful.

My phone boots up freezes and then reboots when i try to unlock it or sometimes it unlocks and then when i try to open anything it freezes and automatically reboots. I can't get into recovery mode, i get the android with the triangle and exclamation point. I can boot into the bootloader and odin mode however. My phone is unlocked and rooted and I have 4.0.2. Is there anyway to do a factory reset from here?
Hello to all
I have Samsung Galaxy Nexus 4.2.1 stock and unlocked.
It worked perfectly to two years! From yesterday i have problem with it! My GN won't boot anymore, I can see just google and X (nexus) logo after that GN restart itself! This is repeated without stopping until I put out battery.
I have tried to clear cache, wipe data/factory reset in Recovery Mode but problem has continued!
I have unlocked bootloader and update to android 4.3 stock (non rooted) through ADB (google SDK), updated successfully but when phone has reboot problem has continued, GN restart non-stop!
In Fastboot mode/Recovery Mode phone it never restarted! I have left in this mode with hours to try if restarted but no It works without any problems in this mode! It restart only when phone boot up!
Can this problem to be hardware failure or not?!
Can anyone help me? What can i do to boot my GN again?
I hope in your your support

Don't panic, this problem is called bootloop and it's normal. Just download factory images from here and flash them by using this awesome guide by efrant!!
Also bookmark this link for future reference.

started having the same problem yesterday after 6 months of stability on a custom 4.3 rom.
oem lock then unlock to format, nothing, tried various methods of flashing back to stock via ADB with mixed results, normally more boot looping with it occasionally booting into a rom for ~5 seconds. so SOMETHING is working.
I tried Efrant's method about an hour ago, but its been sitting at the google logo since, I'm at a lost, I'm no stranger to boot loops when installing borked roms but this is the strangest problem I have ever had with an android device.
should I just chock it up to hardware failure?
Mostly yours USERDATA partition is corrupted.
Use FASTBOOT to reflash the USERDATA IMG and it should do the trick.
Sent from my Galaxy Nexus using xda app-developers app
did a total stock reflash again, got to the setup screen before it rebooted after ~15 seconds, bootlooping again. flashed the userdata img with a few different ones.
I'm trying to read my logcat but when I run the ADB command in clockwork It finds nothing.
I've done all steps by this awesome guide by efrant! But same problem here
I've tried to install 4.2.2 stock, 4.3 stock, all comands works but in the end when i press fastboot reboot my nexus it's in bootloop again restart restart and restart
Any other solutions :crying::crying::crying:
I've waited about 30 minutes after restarting non-stop, my GN boot to system i saw home screen of android but after 5 sec restarted again :crying:
I'm getting into my system once every 10 or so reboots. managed to turn off wifi in case that was the problem but still boot looping. I'm inclined to think it might be hardware related as I started having trouble in the middle of a text after several months of rom stability.
My friend's phone somehow got into a reboot cycle. It loads up, launcher starts, notifications start working. Then there is a nullpointer and a core service that is failing to start then it reboots.
So as a solution I thought try wiping data/cache. When booting the bootloader it was already unlocked - not sure if we did that a while ago or what. So going into recovery, trying the data wipe, it says success and then when I start the phone it is the same, no data is gone, apps are there, reboot problem continues.
So next step, try flashing the os. I downloaded the most recent yakju build, jwr66y. My bootloader version is PRIMELA03 and the build comes with MD04, so I try:
fastboot flash bootloader <bootloader_img>
And it reports success, everything looks fine. So I reboot the bootloader and it says BOOTLOADER VERSION - PRIMELA03.
Try fastboot oem lock, says locked. Reboot, UNLOCKED. Tried flashing the bootloader and the main img with and without restarting but always get the error:
Device version-bootloader is 'PRIMELA03'.
Update requires 'PRIMEMD04'.
when trying to flash the stock rom.
I also can't boot the stock image via 'fastboot boot'. It looks successful up until it says booting and goes to the Google screen with the padlock at the bottom and just hangs.
If I try using adb sideload to push the stock update, it says verifying, then aborts.
I also tried flashing the recovery with a cwm recovery but the same problem - it says writing, OKAY, no error message, everything looks fine, then boot recovery and it's the stock recovery.
What it looks like to me is that the bootloader and possibly the entire system is failing to write to the system flash but for some reason thinks it's succeeding. How is this possible? Is the flash dead? Am I missing something basic? I haven't rooted a phone in a couple years so it's quite possible I'm just missing a step.
Thanks in advance for any advice.
I just tried flashing an older stock (imm76i), starting by flashing the radio, but again the radio flash looks successful but the kernel won't flash because it complains about an out of date baseband and sure enough, the old one is still the one it's reporting, not the one just flashed.
tried fastboot erase system and fastboot erase recovery. Both report success but recovery boots as normal and system boots as normal (still in a reboot cycle).
I should also mention, that after the system boots, there is enough time to uninstall an app. It says successfully uninstalled, but after a reboot, the app is still there (this was the first attempt to stop the reboot cycle as a custom keyboard app was suspected). But again, the changes to flash seem to not be sticking.
Hi,
Have you resolved the problem? I'm in the same situation and I don't know what to do to stop the continuous reboot. I've already tried to flash a stock 4.3 factory image, erase the user data or only unlock the bootloader but nothing works. I'm running Android 4.3 stock without root and my bootloader is locked.
thank you in advance.
Hi my nexus 5x has started bootlooping on the google screen for no apparent reason. I have not rooted the device and it's bootloader is locked. I'm able to fastboot but selecting recovery mode returns me to the loop. I've tried using wugs nexus toolkit to flash stock but the it just returns me to the loop as the boot loader is locked. Is there any way to unlock the bootloader or return to factory settings/get out of the loop?
There is literally like five threads describing the same issue. Take a look in the Q&A forum

I think you probably have failing EMMC. Sometimes if you keep playing with it or let the battery drain, it eventually boots once or twice before going bad again. If this happens you should immediately go into developer options and enable OEM unlocking.
If for some reason you can reinstall factory images and that works great. If not you probably need to try the LGUP method with the TOT file. Search and you'll find it.
If that fails, you probably need to get a new phone.
Hi everyone,
Yesterday my HW1 went spontaneously into a bootloop (continous spinning android circles). I could enter into bootloader mode, and then into recovery mode. I cleared data & cache and after confirm operation the watch started to throw errors and then restarted, but no more android cricles, just the huawei splash, the robot image during half a second and huawei logo again.
So, I decided to reinstall the whole firmware. But now I've found the first obstacle: The watch refuses to make bootloader unlocking. After sending the command via fastboot, and confirm unlocking on the watch screen (fasboot message: "OKEY"), it restarts at fastboot menu but "unlocked:no" is the last line on the screen...
With locked bootloader, I can not flash any firmware...
Please help me to bring it back to life.
