LG D855 stuck in boot loop, even after factory reset

Hello,
I have a LG G3 D855 with unlocked bootloader and TWRP 3.0.2-0 and it had a relatively recent build of the official LineageOS ROM.
Everything was running fine, until suddenly, during a phone call, it shut down, and since then,each time I try to turn on the device, the LG logo appears for 20 seconds, disappears for 2 seconds, and then appears again, over and over again. I can still access the recovery thou.
So I have tried wiping everything, including system, data, and caches, repairing file systems, reinstalling the newest version of lineageOS, (my SD card slot doesn't work so i had to push the ROM file to the data partition using adb and installing it from there). I also tried using a different battery, and the same problem persists.
I am kinda hopeless now so I would appreciate any help I can get.
Many thanks.
I have the exact same problem. It started when I upgraded to latest TWRP. Flashing back to the normal TWRP didn't solve the problem and the boot looping is persistent now and TWRP is inaccessible.
I flashed to stock rom using LG flash tool 2014 and no matter what I try it still loops indefinitely with the new OS installed.

Stuck on boot screen

Hi guys
I have the chinese version with global rom.
Successfully installed TWRP and crDroid 10.0 rom but the google first time setup kept freezing (everything else worked perfect) so I decided to reflash the rom.
When I reflashed the rom it keeps getting stuck on the crDroid boot screen, have left it overnight and same.
Tried reflashing vbmeta, firmware and then crDroid with various wipes but same result.
I would appreciate any advice.

Z2 Plus Boot issues

I was on AEX and tried a new roms (Pixys, Evolution, Pixel Experience etc) and none of them booted the android.
Tried to restore AEX and even that is not booting. Phone keeps rebooting in loop without booting to any os including the restored backup.
Evolution and pixel after a clean installation says "no os".
Phone stays in start mode and does not move beyond this point.
Phone boots to twrp recovery.
Any idea what is wrong? Have corrupted the phone that it can't be used?
Is there a way out?
Quick solution would be highly appreciated.
Thanks
Anyone has a solution/suggestion for this?Deperate now since there is no alternate phone.
Thanks again
The phone boots recovery and adb commands work whereas fastboot commands don't work. I am able to flash vendor2factory and rom successfully with no error but the phone still not boot android but vibrates and goes back start screen and if i don't press any keys it restarts again after showing the ZUK logo.
I hope i have been able to explain the situation. I am still not able to boot the android despite trying more than one rom.
Anyone has any clues? Thanks

I am having the same problem. I was in pixel experience and i flashed latest pixel experiences august security patch, it showed no os but it booted. But there were several bugs in the rom, i thought it was roms problem and then i tried to flash evolution, it again showed no os after flashing and then i got stuck at evolution x boot logo. So, i tried to qfil zui but to no avail, the flashing process won't even start the qpst tool just freezes after pressing the download button. Then in the twrp i noticed that battery percentage is different at different times sometimes it shows correct value but somes it won't so i thought that the problem might be from twrp and then i flashed new twrp but again same problem. Then i flashed arrow os 10.0 without gapps, it booted successfully then i flashed gapps. After sometime i tried to flash evolution x but got stuck at boot logo again. Finally i flashed arrows os again it booted successfully (i flashed rom and gapps separetly)
So, FINALLY THE TEMPORARY SOLUTION IS TO FLASH ARROW OS IT WILL BOOT SUCCESSFULLY BUT THEN AGAIN OTHER ROMS WON'T BOOT. IF I FIND ANY SOLUTION I WILL POST HERE

When you qfil, the recovery will be lost i think. But since you cannot enable usb debugging i think you wont be able to flash twrp.

I think the problem is our phone is not able to boot big rom i.e. roms of size close to 1gb or more than 1gb since arrow os without gapps is only 600mb my phone is able to boot. If you are able to find the solution or get your phone repaired at any cell repair centre please let me know
bro is your phone working now

Clinically dead Redmi 5A - please help

Hi to all, I just want to ask for some advice or tips. The thing is:
I have one old Redmi 5A Riva. It was lying in the drawer some time, so I decided to try to unlock the bootloader and flash some custom ROM.
So, I unlocked the bootloader - OK
Then I flashed TWRP - OK
Then I decided to make root on stock firmware - OK
Then I tried to flash Lineage OS 17 - after flash it stopped booting.
So I tried to flash Lineage OS 18 - it started booting again but I found out that phone doesn´t detect an USB cable, so I wanted to flash some other ROM instead.
But after few moments TWRP suddenly disappeared (volume up + power on stopped working, only vol. down and power on worked to fastboot) - kinda weird, I said to myself Now I am f**ked up because Lineage 18 was not rooted, I wanted to do it later, so I couldn´t use TWRP app to reflash it.
But after few moments there appeared stock recovery menu, so I thought okay, maybe its not dead, so I try to flash just stock rom. I tried MIUI 10, but again - not booting.
So I did wipe again and tried MIUI 9 - flashing via fastboot and used flash_all.bat attached to rom - it booted up and worked, so I enabled USB debugging again and tried OMNI ROM. I flashed it, after flash it boots up, but after few second screen goes black and nothing else happens.
I am kinda annoyed with this , I flashed many phones, but only Xiaomi makes these weird problems.
Can someone help me to fix this?

4 Big problems after flashing back stock ROM on Realme 3

Hi, first post btw, but as the title says, my phone has had problems after flashing back the stock ROM
The previous ROM installed was Lineage OS, and I wanted to go back to stock, so I flashed it using SP Flash Tool, but after flashing the stock rom. I've noticed 3 problems after the flash:
Problem #1
I've noticed the screen was very dim even on the Realme logo in boot, which normally goes to full brightness first then goes back down when booted. When I tried to adjust the brightness, it was not as bright even on max, I've also tried to turn on auto brightness, but no success
Problem #2
There are no biometrics available to use on settings, so I can't use fingerprint or Face Unlock.
Problem #3
The volume is always on max, when I turn the volume down, it shows the volume slider UI go down, but no change in the actual volume. Even when I plugged in my earphones, it still doesn't change
Problem #4
Mic not working, even my earphone's mic isn't working on my phone, but it works on other devices.
I haven't found any more problems yet, but these 4 have been the biggest problem I have, no money to buy a new phone, so it would be really helpful to have a solution to this.
I've already used the scatter file a few times before when my phone was stuck on bootloop, but back then there were no problems, just now.
