[Q] Helping with bootloop - Samsung Galaxy Nexus

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.

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

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.

Stuck in CWM / Crash on every Rom installations

Hi everyone
Sorry in case of repost.
I have a P5210 (Samsung Tab 3 Wifi). Once rooted everything was allright until I entered in recovery mode from the Rom Toolbox app.
I'm now stuck in a recovery loop mode and can't get out (CWM v6.0.4.7)
I've tried everything from factory reset / cache and dalvik cache wipe, to "fix" zips and so on. But nothing changes.
I've tried to reinstall CWM by putting a recovery image into a script and flash it through CWM. Seems to be done correctly, but when I reboot, it's still the same CWM (no update)
Eventually, i've tried to install some custom ROMs to start fresh : Every installation crashes at "WRITING SYSTEM PARTITION". I get black screen and a reboot.
And I've tried every custom Rom compatible with P5210.
Can you help me to get back to a clean configuration ?

Hi
It seems you were on kitkat rom which may have updated your bootloader to kitkat version. The CWM needs to be updated to work well with kitkat. I had similar problem with my SM-T210, and solved the problem after updating CWM as per this post for T210:
http://forum.xda-developers.com/showthread.php?t=2433853
Your tab is different from mine so i think you need a fresh stock rom install using odin, then find an updated CWM for your tab.

[Q] Bootloop on recovery

Hi.
After a reboot a got a bootloop in the recovery. (TWRP) recovery. I can't enter the recovery anymore to fix anything. I can only use the download mode. This happened after I switched to F2FS file system using Resurrection ROM with the AGNI Kernel. The ROM was okay in the F2FS mode, the bootloop occured after rebooting in the TWRP from the ROM..
I have tried Odin in various versions, I tried to reflsh the recovery but it failed. I also tried to reformat using the PIT file. This indicated PASSED but still i was not able to flash a recovery thereafter.
What else could i try????
Many thanks!

Flash the PIT file together with a 4.1.2 stock firmware downloaded from SamMobile. Root and do whatever you want after.
My mix is CyanogenmodX (by UtkarshGupta)+f2fs+agni. It's kinda weird and I did not found someone else with this problem except this topic. I did a lot of reflashing to nail it down to the following:
I'm stuck with a twrp loop (twrp logo appears and then reboots) when using f2fs (/data only) and the system is installed. This problem is now for some months, before it worked fine with the same setup. Also complete wipes of all partitions and even repartition did not help.
-It works as long as there is no OS present or not booted for the first time.
-To fix it, I can either format /system or /data (to ext4). To do that, I have to flash an other recovery.
-It does not matter if I use the format script (as provided in the OT), or with twrp advanced wipe/change partition type (which only works if TWRP is not newer than 2.8.1.0 - newer versions give an error: unable to wipe data).
-The OS itself runs fine.
A strange thing to note: there was a time, where this problem occurred, to fix it, I had to flash an other recovery via odin, boot into that recovery, do nothing(!), reflash twrp with odin again, and I could access twrp again until I booted the OS again. This suddenly stopped and the only fix is the way I described above.
And a site note: the "loop" only occurs when using the advanced reboot options from the OS (or any other tool from the OS to boot into recovery), as it sets a recovery flag. When using volup+home to access recovery, it only happens once, still allowing the workaround to flash another recovery to remove the flag, and able to reboot system afterwards again (but no access of twrp anymore).
I also tried updating bootloader (and modem) with no success.
Process on installing: wiping everything except externalSD, change /data to f2fs, reboot recovery, install CMx, gapps, supersu, agnikernel.
Aaaaany input that might help to resolve this is really appreciated.

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

Unable to Reset - Strange behavior

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?

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)

Galaxy Tab3 7.0 (SM-T210) - Can't flash ROMs, recovery or factory reset + bootloop

Hi all
Been having some issues with a Tab3 that was stuck in bootloop - it would turn on for anywhere upto 10-20 seconds then reboot, and repeat... I tried going into setting and selecting factory reset and it wouldn't allow it.
I then used Odin to flash TWRP recovery then flashed a custom ROM (can't remember which but it was completely de-bloated and had bare necessities). The bootloop continues and still not fixed.
When I boot into recovery I can select all options, re-partition, format, wipe cache/dalvik, etc... But even though I've wiped everything in recovery when I reboot the Tab everything is exactly as it was, as though I hadn't wiped it.
I've tried flashing a new recovery and stock ROM with no success... So, I'm wondering if anyone has ever had this problem and how would you recommend I go about fixing it?
Cheers
I've tried using Odin using re-partition, nand erase all, phone efs clear, PIT file, stock ROM, recovery, etc...
It's not hard-bricked as it's booting up, but for some reason it doesn't wipe or flash to stock and I can't find the solution!!
Any help is appreciated
