Hi,
my gf's D855 (running CM13) has a strange bootloop/crash issue:
It crashes after entering the SIM-PIN, wiping dalvik helped then sometimes.
Today it is widely stuck at looping at the LG-logo. Sometimes it is possible to enter TWRP, so we reflashed the actual CM13-nightly. Booting went fine, but after entering the SIM-PIN, you can guess it, it rebooted. And now it is stuck at LG-logo-Looping. One moment I was able to enter TWRP again and wiped the internal storage, hoping only something there were broken and causing the issues. But now, well, it's looping again
Have you tried flashing a different rom?

My Samsung nexus got a problem. I have TWRP installed as recovery and I tried to install new Cyanogen ROM. I did it clean but it get stuck in "Starting App" for long likely for 2 hrs then I restarted the system just to stuck in boot loop. I did fresh install wiping data and cache as well dalvik cache but the same problem. Before the phone was working fine except the camera. Camera has stopped working issue. Is this the problem for this?
Moreover, I tried to connect to ODIN but my phone is not read by Odin. What is the solution?
The worst thing is I don't have any backup.
Guys,
Need a little help:
My OP3 worked fine for over a month (with 3.2.2, Rooted and with latest TWRP only) and then suddenly went unresponsive i.e., screen frozen. When I restarted the device, it stuck on boot animation. I tried to restored a week old nandroid backup and it stuck at restoring system partition and then... ERROR 7. I tried the factory reset and got the same result... ERROR 7. I tried flashing the from the scratch as well as formatting all partition, still no luck and ERROR 7 persisted.
I switched to OP3 recovery and wiped data and cache and the wiping worked but... when i tried to push the rom, it didn't work and it was stuck. i flashed twrp again and tried sideload, still no luck, it got stuck at 4%. I did a wipe again and tried to restore the old backup and the restore simply got stuck (no error - i waited for 30 mins).
So, my question is two part (before i send the device back to OnePlus): any idea what is going on and how can i fix it? and is there any other way i can try to do an absolutely clean install of rom and try if that works?
Thanks,
Answering my own question: device sent to OnePlus and the issue was identified as faulty motherboard.
I just got the phone, so I have nothing installed and nothing to loss at this time, luckily.
I have unlocked and installed Codeworkx TWRP and Magisk for root.
The phone was fine, I configured some settings then rebooted to TWRP and made a backup, before installing anything.
This is when I encountered the issue:
Upon rebooting the phone is stuck at "Android is Starting..."
Now I can unlock (pin or fingerprint) and access settings, but only settings as I have no launcher.
I tried rebooting and wiping the cache and Dalvik without any change
Since I'd restarted more than once without issues I can only assume the cause was performing a backup via TWRP.
Now as stated I have nothing installed I can wipe anything and begin again, but if this happened in a normal situation, I'd be in real trouble. Any Ideas why this happened?, as it seems very odd that I can access the phone and setting, but can not get a launcher to start.
More over any suggestions on how to fix it short of reinstalling?
I'm very worried as this would make the phone unusable if it happened in a normal situation.

Your installation or use of TWRP probably has nothing to do with it.
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.
This a bit of a long short story, so please bear with me for a while.
I first unblocked my Lenovo K5 Vibe Plus a6020a46 (India) in 2017 and using TWRP I had flashed the AEX Oreo v5.7 ROM. It was a great change and everything else was working fine for a long time.
Fast forward to 2020, I felt the phone was slowing down so I clean flashed AEX Pie v6.7 using TWRP, the ROM worked slick but after some time weird problems started to rise. Here's the chronology of what happened:
1. While using some apps the phone used to freeze, then shutdown. A restart would solve the problem for a while. But the lag used to remain.
2. The same problem repeated after a while but this time the phone went into bootloop.
3. I wiped cache, tried other solutions but nothing worked out so I reflashed the same ROM after a clean wipe. Phone worked fine for a week but then slowed down and finally crashed (This happened 2 times.)
4. After a week it was different, this time the boot animation would get stuck, then the phone would crash. So I reflashed again but when I booted up the phone there was no SIM service, no iMEi, No Wifi, No IP, Bluetooth.
5. I thought this AEX Pie ROM to be a problem so I flashed Arrow OS, Paranoid OS, AEX Oreo version, AEX 10 version but the problem remained: The phone would boot, boot animation stuck, and the phone would crash. This loop is where I am now.
I followed THIS GUIDE and tried reverting back to Official Stock ROM using QFIL. The flash was successful but the phone wouldn't bootup and went into a restart loop.
Here are some more important details:
1. The recovery mode is working fine. I can flash and wipe but I sometimes get the error of "Unable to mount" on Data, System and Cache partition which is solved with a format.
2. I can also get into Fastboot mode, EDL mode for QFIL flash.
3. I can also view all files and folders from TWRP Filemanager.
TLDR; Phone keeps crashing on boot, reverting to stock ROM also leads to restart loop, the phone shows no SIM, Wifi, iMEi, IP, etc. Tried wipe, clean flash, format which is successful but the problem remains. HELP!
"4. After a week it was different, this time the boot animation would get stuck, then the phone would crash. So I reflashed again but when I booted up the phone there was no SIM service, no iMEi, No Wifi, No IP, Bluetooth."
This is caused by bad ROM flashing ( when your flash wasn't entirely successful). You can fix this by reflashing. This could also happen if you downgraded, so go back to the version uou were on and see if this did it. You can fix IMEI with root if you want, I saw a thread for another phone: https://forum.xda-developers.com/g5-plus/how-to/fix-persist-resolve-imei0-explanation-t3825147 see if this could help.
"Animation Stuck"
This could be a problem with the ROM and data/cache, try factory resetting. Otherwise, it is also a problem with the ROM
In any case, I would redownload and reflash Stock ROM again and see if it still happens.
