Unable to Reset - Strange behavior - Samsung Galaxy Nexus

Hi everyone,
yesterday my beloved galaxy nexus started rebooting continuously. I did not even touched it. The loop is continuing still now without any reason. Usually, in this occasions, I've performed a clean/hard reset (I don't know the correct term), wiping system, data, cache and dalvik partitions, flashing a new rom and bla bla..
The very strage thing today is that I'm not able to do that. I'm using the TWRP custom recovery: if I wipe something or perform a factory reset (standard in twrp) it starts the process, gives me at the end the advice that everything has gone well, it even allows me to flash a new custom rom and gapps but when I reboot, nothing has changed. It reboots in the previous system, nothing erased and again with the reboot loop.
I've just tried also using fastboot interface. Any command I launched performed its task, the phone gives a positive ending but when I reboot again, it's like nothing happened.
Specs: Galaxy Nexus Maguro, GSM version. Actually running a 4.4.4 rom (SlimKat) with its own kernel. A lot of customization (writing/formatting) in the past 2 years.
Thanks in advance for your help!

Did you try CWM recovery?
you can install it using flashify from Google Play...

My phone reboots in 10 sec after he boots. I can not install flashify and not even flash cwm recovery.

The same here
I'm having the same problem here, it seems that It's not saving any change I try to make, as you've described it says that every task was performed ok but after rebooting it has all my apks, data etc. even afer wiping.
The only thing I can make to keep it ON, is to enter in SAFE MODE, then I can save my pictures and data but I can't flash anything (well I can but it make no change).
FACTS:
-If you start the phone and you activate USB debugging, after rebooting it's not active anymore
-It shutsdown after 10 secons entering in a boot loop (unless you use SAFE MODE, that way you can keep it on)
-If you wipe data, wipe cache, flash boot, flash bootloader, flash system, unlock boot loader, root it, restore, flash stock + unroot (using nexus root toolkit v2.0.5) or use any flash option of fastboot via command line including update, you will get task perfomed ok but nothing is changing; after rebooting It shutsdown after 10 secons entering in a boot loop and all my data including APKs, pictures etc are still in the device.
-You can boot in Download mode, Recovery mode
Phone spec.:
Galaxy Nexus GSM/HSPA+
Android 4.3.0 JWR66Y
Product name: Tuna
Variant: Maguro 16GB
Bootloader Version: PRIMEMD04
Base Band Version: I9250XXLJ1
Lock State - Locked (You can easily unlock it but after reboot it'll be locked again)

Stuck in CWM recovery loop

Hey,
I'm trying to flash NEXPlay onto my device and I'm having a problem, my phone keeps going into a CWM recovery loop. I've tried twice to get this to work to no avail.
There are no instructions on how to flash the ROM correctly on the thread from what I've seen so I followed the steps provided on my other ROM's thread (NXT Lite). I flash the .58 Enhanced firmware using FlashTool and then select "FastBoot" and then "Reboot into fastboot mode (Via ADB)". I then click "Select kernel to Flash" and flash the Kernel that is required.
The phone then boots to recovery so I cleared the cache partition, Delvik cache and wipe data. I flash the ROM and it takes a while (probably due to the size) and finally it says "Successful". I select "Reboot system" and the phone shuts down, displays the "SONY NEXPLAY" logo and then boots into recovery. I keep restarting and it keeps doing this.
Any ideas on how to fix this? If it persists I might just go back to NXT Lite. I have an R800i model with unlocked Bootloader.
*EDIT* I just installed exitrecovery.zip and that doesn't work either. I have no idea what is going on.

[Q] Performed factory reset, now won't boot

I'm selling my HTC One (stock ROM, unlocked) so I wanted to wipe my data, apps and settings. I performed a factory reset/data wipe in CWM and rebooted and it would get stuck at the Verizon logo. I cleared cache, tried again, and got stuck at "Android is updating, Starting apps" for a good 20 minutes. Now it goes back to the Verizon logo.
Does the factory reset not leave the ROM intact? What can I do now just so it'll boot to a clean slate?

Download the stock rooted odexed ROM from here: http://forum.xda-developers.com/showthread.php?t=2485319
After you flash it, wipe data and boot up.
Then flash the latest firmware and stock recovery through Fastboot (also that thread), and do another factory wipe using stock recovery.
Your S-Off / Unlocked status will not be affected by this.

Thanks for your help. Unfortunately, I've been at it for a good 5 hours now and I can't get past the first step.
Using TWRP, I've tried adb push <rom.zip> to /sdcard/, /mnt/sdcard/ and /data/media/ and every time it says it's successful, but the directories show up empty in TWRP. Without a removable SD card, I'm not sure how else I can get the ROM on the phone for flashing. I'm not sure if it's related or not, but everytime I reboot from TWRP, it says my phone isn't rooted. I select "Install" but it occurs again, even though supersu.apk is on the internal storage.
I also tried CWM but couldn't get past "format () expected 5 args, got 4. Installation aborted (Status 7)".
Does anyone have any suggestions on how I can get TWRP to flash the ROM? Thanks.
Try this cmd instead.
Code:
adb push nameofrom.zip /data/media/0/nameofrom.zip

I recently returned my phone to stock in order to reset all the firmware and RIL data. Here is how I did it:
Enter recovery TWRP 2.6.3.4 (if you have 2.6.3.3 you may experience issues)
Boot into recovery, then format Data, System, Cache, and Internal Storage (this will leave the phone with NO ROM installed)
Reboot back into recovery. Answer No to the prompt to root your device.
Once back in recovery, Internal Memory will be available again (if you push the ROM before rebooting, it will not be there afterward)
Push the ROM using adb push ROM.zip /sdcard/ROM.zip (this will take 5-7 minutes for a 1.4GB file)
Flash the ROM in TWRP
Reboot when done, phone should boot up corrrectly
Reboot into Fastboot, push firmware.zip package
Reboot into ROM verify connectivity
Reboot into Fastboot, push stock recovery
Reboot into stock recovery, perform a Factory Reset
Boot into ROM
Once you are up and running on the latest 4.4.2 ROM with stock recovery, boot into Fastboot one last time and push TWRP 2.6.3.4. Your S-Off will not be affected and the new owner will be able to flash any ROMs they like.
If all of the above fails, then try using ADB Sideload from the Advanced menu in TWRP.
You guys are a life saver. TWRP 2.6.3.4 did the trick, it just wasn't available on the TWRP site so I didn't install it in the first place. Flashed the ROM and everything back to normal! Thanks for the help!
FWIW, none of the m7 versions of TWRP would load (stuck at "Entering Bootloader" screen). The Sprint version would load, but wouldn't mount the filesystem properly.

So what state is the phone in now? Stock w/ HTC recovery, or the Sprint TWRP?

The former, stock. The Sprint TWRP loaded but didn't work right. I ended up finding 2.6.3.4 for VZW m7 on an xda thread, it's not on the TWRP site for some reason. That worked great.

Excellent. Glad to see it all worked out.

[Q] Helping with bootloop

Hi guys! I have a problem. I had paranoid android as rom and it worked great! Some days ago while i was using Facebook app there was an overloading of memory (i think) and there was the reset of the Nexus. From that moment the cellphone is in bootloop. I can access in the recovery (CWM). I tried some methods:
1)in recovery mode i tried to wipe everything but nothing
2) i used nexus root toolkit but nothing... also enabling the option softbrick/bootloop
3)using gnex toolkit... the same
4)using Odin too but nothing to do
What can i do ??
Thanks
PS: all these methods that i tried seem to work but when i turn on the phone it is always in bootloop -.-

Same problem here
Am facing the same problem here.
Was on cm11 and one fine day without any issues got into a boot loop. My phone is encrypted, so during boot, it asks the password and even logs into the phone, but within 5 seconds, it goes into a reboot.
Tried almost everything i could find.
erasing/formatting from fastboot - shows success but logs into cm11 again with bootloop
Trying to flash stock - everything shows success but still back to cm11 when rebooted
trying to format mke2fs -t ext4 /dev/block/mmcblk0p12 from recovery- still nothing
flashing through odin - no change.
The crazy part is, everywhere it shows success and when it finally boots system, its booting cm11 and asks for password to decrypt data. And after booting goes into a reboot.
The only place i see any failure is when trying to format /data from twrp. It says its not able to mount the partition.
Any pointers anybody? Can't think of anything else which i can do to fix this issue. :crying:
I had same probleme after install lollilop rom:
[ROM][5.0.1/LRX22C][AOSP] AOSP Lollipop: a wee better than stock.

1)in recovery mode i tried to wipe everything but nothing
2) i used nexus root toolkit but nothing... also enabling the option softbrick/bootloop
3)using gnex toolkit... the same
4)using Odin too but nothing to do
If anyone get a solution ?
I had same probleme
I had same probleme after install lollilop rom FML-AOSP-5.0-20141207 Recovery: CWM V6.0.5.1
I've tried everything from wiping erasing and reflashing & reflashing data, wiping cache, davlik cache, system, internal storage. I did the factory reset in CWM recovery to wugfresh toolkit's "flash stock+unroot" with odin mode All finished successfully according to fastboot , recovery , odin but a reboot showed the system in the same state as before.

T700 Soft Brick

Looks I've managed a soft brick. I've been able to get it back into recovery and I've been able to push stock recovery (and also just tried TRWP). Odin seems to work and the T700 appears to accept the recovery. Following reboot I'm still getting stuck back to the Samsung boot animation but then I'm stuck at the boot screen; nothing past that.
I'm not sure if this should help any, but while in recovery mode the upper corner reads the following:
ODIN MODE
PRODUCT NAME: SM-T700
CURRENT BINARY: Custom (after flashing TRWP, when flashed with stock it said 'Samsung Official')
SYSTEM STATUS: Custom
I would appreciate any assistance and thanks in advance! This is my first soft brick since Eclair!
Have you tried flashing stock firmware with odin? Or restoring your twrp backup?
Firmware, yes. I flashed TRWP to see if I could restore a backup, but after the initial reboot after the TRWP flash the device still returns to the Samsung logo.
Try download mode then restore to stock using Odin and then go into stock recovery and reset then wipe cache and reboot.
Sent from my SM-T800
I've tried that but perhaps I'm not following the proper set of instructions. Would you point me in the proper direction? I won't be offended by 3 year old instruction sets.
(This is stock recovery)
Reboot your tablet into Recovery Mode
Next, take the following steps using the Recovery Options:
– Wipe data/factory reset
– Wipe cache partition
Back to main menu and reboot using the option reboot system now.
If that doesn't do it then I dunno. I know it helped me after messing around with flashing and whatnot.
I don't even bother doing it anymore. I just root stock and add/remove the stuff I don't want.

I decided to walk away from it for a day and some change. In the meantime that allowed for the battery to run out. It shouldn't have had a bearing on the fix, mostly because - well it just doesn't make sense - but after charging full following the drain it took a firmware flash to stock.
I appreciate the sanity check!

Bootloop in recovery

hi,
for the past hours i'm trying to flash skynote 9.3 after long time on some other 4.1.2 rom and i am having troubles after the flash, i wipe system, cache, dalvik, etc but after i select reboot now i get a prompt about root is missing with a No option and a yes (Install root) , the phone goes to samsung logo and then after a second reboot goes back to recovery! I have tryed twrp 2.8, cmw6.0.4.3 and phliz
i search througt the forums and the closest thing i came up is with this post
i have tried a stock firmware from odin first in case it was the bootloader...
any thoughts?
Hmm i dont know why but i have same problem on my Alcatel 4034x, until i bricked recovery and it booted into system without problem except now it looks like rom is poorly made, it automatically filled up dalvik and cache partitions and now i cant boot into recovery, fastboot or system. Its just stuck on alcatel logo. I also tried to flash it with sp flash tool, didnt work cuz drivers arent "signed" for some reason. Someone help me too pls
