I have observed suddenly my Zenfone Selfie-ZD551KL is not able open after flashing any stock ROM. I have tried almost every version (MM, LP) official firmware through stock recovery & adb flashtool. Everytime its restart to boot logo after flashing any ROM & never booted up. Even I flashed RR-N & CM13 Custom ROM via TWRP recovery but its never booted. Every ROM shows successfully flashed but my device continuously restart on boot logo. Please someone help me to fix it.

SAME!
Me too, after flashing LineageOS i reboot to fastboot mode too. even if i remove my battery and normally turn it on still on fastboot mode. i really need help. im getting desperate :crying:

Same problem with me, but I'm stuck in infinite loop in the bootanimation of Lineage, RR, AEX and others. Only Stock Rom works normally. Does none of the XDA Developers have a solution?

did anyone find a way to fix this ?

[Help] mi 9T boot loop after installing lineage os

I have unlocked my boot loader and tried installing Extrended Ui, but every time i flashed the rom with TWRP it showed a message saying "no os installed", when rebooting is got stuck in the mi logo, the rebooting in TWRP i installed Lineage, when rebooting the No Os warning didn't appear, so i think it worked but it never passed the lineage boot animation, i the tried installing the stock rom that its in the Havoc Os thread but like Lineage it gets stuck in the boot animation.
Any solution you might know?
I installed the frimeware every time before a rom installation

Download and flash this firmware first and then flash the ROM you want.

Please help. Stuck in bootloop

I have a Lenovo A6000(not+) . I flashed resurrection remix 5.8.5 a few days ago. Everything was working properly. Yesterday I flashed the hex firmware patch as I wanted to try lineage os v17.1
Today. My phone is stuck in bootloop and I can't boot into neither recovery nor bootloader. All will reboot to splash screen in 20 seconds. I tried to use bugjaeger backup internal storage but couldn't as the phone restarts in 20 seconds. Please help. I can't even flash a new rom also.

Fixed it myself. The screws near the battery were loose so it could not boot properly. I tightened them and the first boot took a few minutes. Now it's functioning properly.

Unable to boot into custom recovery

I have the Nexus 7 2013 wifi edition, it's been sitting here for a bit so I decided to give it new life by flashing lineage os on it.
Well the issue starts with the recovery, when I do `fastboot boot recovery.img` nothing happens, tried both the lineage recovery and twrp.
At the top of the screen it shows `booting downloaded image`, but nothing happens, the device actually freezes.
This device is stock, updated and unlocked.
Any suggestions?

I have the same tablet and the same problem. I have also tried both the lineage recovery and twrp. It just hangs...
Help?!
