[Q] boot looping before and after stock flash - Samsung Galaxy Nexus

My phone suddenly crashed and started boot looping, so I flashed a stock rom via fastboot (I've tried flash-all, erasing everything and flashing the sys/recovery/boot manually, and using toolkits) but it's still boot looping afterwards. I've tried doing a factory reset in both the stock recovery and cw and twrp, but to no avail.
What is up with my phone? Is it just dead?

I should add that I've flashed a bunch of different custom roms by sideloading via adb, and they all boot loop as well.
Do you think the internal storage could be corrupted somehow?

boot loop

My new GN is stuck in a boot loop, Ive tried wiping and factory resetting but this did not work
Any ideas?
Also tried recovering from a nandroid and it fails at restoring data.
Any one ?...
If you can get to recovery just flash a rom. If you don't have a rom on the device you can use adb and push one to the sd card.

Bootloop after downgrade from L Preview..

Hey, I have an issue with my tablet after I wanted to go back to kitkat from the L Preview.
I had 4.4.4 and decided I'd like to try out the L preview
So I downloaded the img from Google and flashed it via fastboot, worked perfectly fine but not as stable in apps as it was on kk.
So, I downloaded the latest factory image from the Google Developer Site, extracted it and ran the flash_all.bat
Seemed to flash ok, no errors, rebooted and started to boot but it only goes as far as the spinning boot logo. No further.
After leaving it a good hour or so I decided it clearly wasn't going to boot I went back into the bootloader and tried to get into stock recovery mode but after rebooting it just stays at the white Google logo..
So, I tried to flash TWRP via fastboot. Again no errors, successful flashed but just like before it sticks at the Google logo and never boots the recovery..
I even tried the "fastboot boot recovery.img" but then it just freezes on the bootloader.
I've also tried the 4.4.3 img.. same happens.
Now if I reflash the L Preview img via fastboot it sticks at the Google logo and didn't even reach the boot logo!
Sounds to me like the partitions have gotten corrupt? Though the imgs are flashing successfully without error so I don't think it's that..
But.. recovery partition is broken as I can't get into recovery at all, and it freezes if I try.
Anyone any idea what could have happened?
All I did was flash the KK factory image over L, just like I flashed L over KK and it worked fine.
All the guides online do the same thing to downgrade L to KK.
Is it bricked? Can it be recovered?
I still have bootloader access with fastboot..
Any help is greatly appreciated!
I finally managed to enter the stock recovery and it appears that the /cache partition was damaged or corrupt. Strangely it would get corrupted each time I flashed the factory image, even flashing the cache.img directly..
However it seems to have fixed by doing a factory reset and /cache then formats correctly and android booted fine after this :victory::laugh:
As you see in the image, when entering recovery I was presented with a bunch of errors regarding the cache.
Tried to wipe cache but that fails.
Did a factory reset and cache seemed to format fine.
Did another wipe cache and this time it completes without the error I got before.
Then rebooted, Android began booting and thankfully it's now working fine again!

Can't boot into TWRP on Nexus 5X

Hi guys, having an issue loading into TWRP recovery on my Nexus 5X. I upgraded to 3.0.2 from 2.8.7 (I was having issues with storage not being mounted when trying to flash gapps, so a thread suggested upgrading TWRP).
I flashed the new TWRP with flashboot and it flashed fine, but when I rebooted into recovery it booted my into CM. I have tried a few methods to get it to boot but to no avail. I saw in another post to use fastboot and erase recovery before flashing, that didn't work either. I even tried doing a method using Odin, but my phone won't boot into that download mode either... it just continues straight to CM. Any suggestions? Thanks!

Soft brick that won't quit

Was trying to update the supersu binary by installing the updated zip in recovery. On reboot it was stuck in a boot loop. First off nothing else worked, then fastboot worked and then 10 mins later twrp recovery started working. I tried to restore a backed up image but still got boot loop. Then tried to flash a rom I had on sdcard - still boot loopy. Tried to go the miflash tool root but couldn't get it to find the phone despite it appearing in explorer. Copied stock miui zip onto sc card from pc and installed but still same problem. Standard dalvik/cache wipe before and after each install. Now I'm struggling to get recovery up.
Help - haven't managed to totally brick something despite many years of tinkering. :/
PS. I can still get fastboot up. Now when I try to get recovery up the screen goes black and I have to reboot.

If you don't have a backup, maybe you can wipe and side load a ROM via ADB.
The thing that worked for me is flashing the 1450 stock rom, then flashing the custom rom again
Probably encryption fault, you will have to wipe and reinstall your ROM.
Same thing happened to my robin as I got an update to Lineage OS for Oct 23, and the phone was supposed to boot into recovery and flash the rom but nothing happened. I tried to look for the update rom inside the phone but couldn't find it. I then rebooted the system and it booted right back into TWRP recovery. I even wiped the whole phone and reflashed the rom again and still no dice, I even tried that stock flashable rom and nothing worked.
