[SOLVED] Bootloop even after flashing factory image - Nexus 5 Q&A, Help & Troubleshooting

Hello guys,
I need some help please, because I'm out of ideas.
The issue:
I was using the Cataclysm Rom for months without any problems. Today I restarted my phone (I do this every other day, when it gets a little bit slow) and it stuck in bootloop.
I tried wiping dalvik/cache, doing a factory reset, reflashing Cataclysm, nothing worked. So I decided to go back to stock (using http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701)
and I'm still stuck in a bootloop every time. I can access and use fastboot/stock recovery in the normal way, but it won't boot..
Could someone please suggest what I could do?

Pseudo Reset after boot loop on i9003 possible solution

hi everyone
Ive been getting Samsung boot loop and my phone semi resets (loose contacts, apn settings, market app crashes) once i take out the battery. I tried flashing many stock Roms but it was happening all over again.
I knew my problem app was Google maps.
My solution to the problem was:
1. i rooted the phone.
2. installed titanium backup
3. with titanium backup i deleted corrupted app (google maps)
4. Do not reinstall previously deleted corrupted app or boot loop will happen again
Hope this can solve you problem

If you can boot into Recovery mode, then just try Cf-ROOT by Amit Bagaria.

[Q] boot loop after flashing factory image

hi guys,
I use to reflash the factory image on my nexus 5 every here and then. Since a few days I have the problem that every time I do this and the device reboots afterwards I get a boot loop.
Altough I can 'fix' this everytime by booting into stock recovery and doing a factory reset I find it weird because until recently it never did that...
Is there anything I might be doing wrong or that I can do to fix this?
Thanks in advance!

If you don`t use erase and flash userdata.img do so, that may solve the issue.

[Completed] [Q] I need help with a Samsung Galaxy Tab 2 10.1 GT-P5113

Hello community, I am new here so I don' t know where to put this.
Well I need some help, I am having problems with my old tab, A Samsung Galaxy Tab 2 10.1 GT-P5113, Flashed with custom ROM CM 10.1.3 for GT-P5110
Worked fine for a year and a Half, the issue that I am having now is that, it constantly restarts, after entering to the OS I can tweak change etc, but after a few secs it just turns of and reboots the system.
The other problem that I am having is that I tried everything that I could think of. I deleted some apps, which came back after the reboot. I booted to safemode, and deleted the last apps that I installed, still came back after the crash reboot.
I went to recovery mode (CWM) and did a Factory reset, delete cache and delete Dalvik Cache. Nothing when reboot everything was like last time.
wen't to and tried to reflash CM 10.1.3 (stable) following every procedure and nothing everything was back.
Last thing I tried is ODIN with stock ROM (which is hard to find for this tab.) but get write error after going to half. I am downloading a second stock ROM (android 4.1.1) to see how it goes.
Hope to find help here, I would be greatly thankful.
EDIT: Flashed now with the new stock ROM, ODIN says success, everything seems fine, but again I got received by the same splash and the same logon screen, and still crashes and reboots...
I really need the help

It keeps with the boot loop.
Hi, thank you for using XDA Assist. After you flash with Odin go into the stock recovery and do a factory reset. If that doesn't work it may be that you're device is just getting old and giving up the ghost. There's a whole forum for your device which may also help. See this,http://forum.xda-developers.com/galaxy-tab-2
Oh, that would be bad news :/
Do you think it could be that I deleted CWM rommanager app, and then accidentally deleted the .recovery, that put me into this situation?

It didn't work. I noticed that after the transferring of odin it doesn't go to the installation procedure. It just skips that and goes to the logscreen with how everything I had.
Now I went to safe mode, and deleted all apps that I could from play store. when I came back after a restart, everything was there, back. :/
Please ask any further questions you have on the q&a forum in your drives forum, the link I gave you. They are the experts on your device

[SOLVED] Constant reboot, need urgent help!

Hey guys,
I have encountered a serious problem on my device. Today I rebooted my phone once and it has just stuck on the samsung logo. Then the phone began to reboot without ending....It could not just start. With the help of TWRP I have made a full wipe and tried to reinstall my actual firmware Superman 1.10.5, but I always stuck at 25%, the phone did not respond to any actions. I even tried to flash the stock 4-file firmware with Odin, but it did not help, the phone constantly reboots. Sometimes it manages to boot to the stage where the sign "installation of applications" appears, but a while later it stucks again and reboots. Please, help me to solve the issue, because I am begininng to think that it would be unpossible to recover the phone. I am only able to enter the download mode or recovery, anything else does not work.
Thanks....

Really sad to hear that story mate. First things first, I assume your BL version is matching with the firmware your flashing right. And when you go to TWRP, can you see /system and /data partition from the mount menu? If not, you have to perform a factory reset. I had issue like that with my Galaxy S7 and usually factory reset(not wiping) helped me with that situation. Since your system can boot up, but crashes after awhile, I do suspect that some of your partition might be corrupted(at least its what happened to me). So trying factory reset can be a good bet for you.
And... I think you have to provide more information with which variant you are using, and your BL version, TWRP version too, solve the problem quicker. Hope this information helps.

Yep, you are right, BL versions always matched firmwares. I tried to wipe the phone with TWRP 3.0.2.3 and also to make a factory reset with the stock recovery. The stock firmware, which I tried to flash, was G930FXXU1BPH6_G930FOXE1BPH1_SER consisting of 4 files including BL,AP,CP and CSC. After 3rd or 4th flash of the same stock firmware the phone suddenly became alive and began to boot. Wu-huuu:silly: I was happy as a child. After having successfully launched the stock rom I have again flashed TWRP 3.0.2.3, went to "wipe" option and formatted data. Then I have installed a Superman Rom 1.12 and everything went the right way. I don't understand only one thing: why after having wiped the phone several times and having reseted it through the stock as well as TWRP recovery it didn't want to boot.
As you said, I suppose that the one of partitions was corrupted. Oh damn, I thought that I won't be able to resuscitate this phone.
I have flashed about 20 phones during my life, but I have never ever encountered such serious problems.

Question Auto restart problem

Hi I once rooted my galaxy a12 but clean flashed it with stock rom but now the phone can randomly restart even when I'm using it, i tried wiping cache and did factory reset many times and even repeated flashing the stock rom but my phone still restart itself while using it. Can someone help please
I faced the same issue, I've solved freezing the cidmanager app.
There's some apps that read the system logs, maybe you can post them here when it happens. Maybe someone will understand.
Update:
After flashing about two week ago the stock rom with magisk, the phone start rebooting itself after the startup or a reboot; even after freezing the cidmanager app. I've finally solved the issue, don't ask how it's possible... but flashing this debloater https://forum.xda-developers.com/t/wizzrom-creator.4300953/ fix this issue. No more random reboots.
