ZE550KL Bootloop, Fastboot and Recovery Accessible - Zenfone 2 Laser Q&A, Help & Troubleshooting

Hi everyone,
I just got this phone with peculiar condition.
It keeps restarting on Asus Logo. I can access fastboot and recovery though.
I've tried flashing stock ROM (UL-Z00L-WW-21.40.1220.1998-user.zip and UL-Z00L-WW-21.40.1220.2196-user.zip) but still it keeps restarting.
After tinkering a bit, I am able to unlock the bootloader and flashed TWRP. Tried reflashing stock ROM, but still bootlooping.
Any ideas how to fix this?

Can only boot to bootloader

So I unlocked my bootloader on my Huawei P8lite ALE-L21 yesterday and flashed twrp recovery. Trough twrp I tried to root the phone by flashing.. It sort of failed and I got into a bootloop.. Then I tried to get out of the boot loop by trying methods I found online. Other's did nothing so I tried to flash boot, recovery, system images.. Now it won't get in a boot loop but I get the huawei logo for 3 seconds and the phone turns off. I can only boot in bootloader.. Is there any way I could still make it work or is it completely lost now?
Update: I flashed Boot.img and recovery.img again and now im stuck at the point where huawei logo appears, but not turning off phone. I am also able to get to recovery now.
Update2: I flashed a different system.img now and suddendly the phone started working.. Problem solved I guess.

Can't flash recovery, boot into recovery or do anything.

Hello!
I just repaired the display of my OP2 and when turning it back on it went straight into bootloop. Only showed the OP Logo and android on the bottom. ADB obviously doesnt work and tried to all partitions via fastboot to get fresh start. After completely resetting I unlocked the bootloader again just to be sure. Then I tried to flash twrp 3.2.1-0. it say dtb not found error. I tried a twrp 3.0.0-0 and it said succesfully flashed but after automatically rebooting the screen just turns black. I can the into fastboot mode or into bootloop can't do anything else. I also tried the MSM8994DownloadTool.exe but it just returns into bootloop again or turns black.
Help pls

SM-T555 Bootloop

Hi
I have tried to flash TWRP to my sm t555 but now i got only bootloop on samsung logo.
After that I had flashed stock recovery - but still nothing.
OS - 7.1.1 - Nougat
I can go to download mode
after going to recovery mode - hang on samsung logo and shut down,
after normal boot - bootloop.
What can I do?
I have the same issue after trying to root.
Did you find a solution?
edit:
I managed to succesfully flash TWRP from this thread, however it didn't resolve the bootloop problem.
edit:
I wiped everything and flashed official ROM, this solved the problem. Then I rooted using different method
