OnePlus 3 bootloop after flashing TWRP

Hello everyone,
I have a huge problem with my OP3. I flashed TWRP following this guide from the unlock of the bootloader to the flash, but when I rebooted from TWRP after flashing it, the phone was in a bootloop.
I also had this problem on my OPO everytime I flashed TWRP, but I solved it by doing a factory reset from TWRP just after flashing it, it always worked, but apparently it doesn't work on the OP3, so I don't know what to do... :crying:
EDIT : I repaired my OP3 by flashing the stock recovery and reinstalling Oxygen OS in sideload, but now I'm afraid to flash TWRP again... I don't understand what I do wrong, I just enter the command to flash recovery, then when I reboot the phone bootloop...

Flash ROM - i'm going crazy here!

Hi,
i have a Helium 128G and got some problems with the radio. Currently i was on 8.1.5 following the guide
http://forum.xda-developers.com/mi-max/how-to/guide-install-global-miui8-root-t3435594
and i also officially unlocked the bootloader after this.
So i thought - to flash a new radio - it would be fine to just flash the 8.1.9 over the updater method. Unfortunately the phone rebooted in TWRP and flashed something. After this the reboot took >10 Minutes so i rebooted into TWRP and found the internal storage is encrypted now. So all data lost. Great!
Nevertheless i tried to flash 8.1.9 via Mi Flash. This worked and the phone booted but after i flashed TWRP it won't boot anymore. What is this? Is it even possible to run 8.1.9 rooted with twrp?
Thanks for your suggestions, i'm really pissed at the moment
EDIT: My TWRP Backup with 8.1.5 worked and now i have the radio from 8.1.9 and the rom 8.1.5. Nevertheless i would like to have 8.1.9 rooted with twrp

Hi! I've also experience your problem, did your phone entered recovery mode after flashing TWRP? if not try flashing the 8.1.2 ROM through EDL (power+vol up+vol down) then after letting the first boot finish flash TWRP. Hope this help

I'm not sure but at one point i saw the xiaomi recovery picture!? Now it works with my 8.1.5 backup again but is it really that heavy to just install a current version when on twrp and root!? i'm officially unlocked for that.

Tried flashing Lineage OS but ended up stuck in a boot loop.

I unlocked the bootloader following Motorolas steps. I then flashed the latest version of TWRP avaiable on the development forum and then flashed Lineage OS + the root zip they provide and gapps. I couldn't figure out how to get out of the bootloop so I've since gone back to stock. Any idea what I was missing?

Lineage:

Did you read the notices and entries on the Linage last pages of the thread that people are having it fail on the install, the latest release? That would be a clue...

I even tried flashing Pure Nexus but that too was stuck on a loop. I left it for about 10 minutes as it was loading. :/

I did the same thing like you on my first attempt, on my second I was able to install Lineage OS successfully. I'll provide the steps I did.
First attempt steps:
1. Unlocking the bootloader using Motorola website
2. Installing TWRP from the same link in your post.
At that point I tried booting the phone, but the phone was booting to TWRP only, tried wiping, format data from TWRP with no luck.
3. From TWRP flashed Lineage OS zip file and GAPPS nano package (the latest version of TWRP is able to see SD card).
At that point I was able to to boot LOS only after executing "fastboot erase user data". Doing the same from within TWRP was not doing the job. The problem was that after each reboot the phone was getting into bootloop again and "fastboot erase userdata" was necessary.
4. At that point I noticed that TWRP thread starts with warning that you have to install a patcher to disable this "verity" feature of the bootloader may be. And I installed the patcher "Verity_FE_patcher.zip"
The patcher didn't fix the issue and went back to stock Nougat using the guide below:
https://forum.xda-developers.com/moto-z-play/how-to/moto-z-play-reteu-firmware-otas-t3557917
First I tried "flashall.bat" , but it didn't wor.k and I flashed all the files manually using the guide . The phone booted normally and I updated it with one OTA update.
Second attempt steps:
1. I wanted to install the verity patcher before anything else and I boot TWRP 3.1.0.1 without flashing it. It booted normally and I realized that the SD card was formated and the patcher zip file is not there. I reboot the system and the phone got in bootloops again even the TWRP was not installed. I coppied the patcher zip, LOS zip, GAPPS zip on SD card . I tried to boot (without flashing) TWRP again, but for some reason TWRP was not able to boot.
2. I flashed TWRP
3. Booted TWRP and flashed verity patcher.
4. Wiped from TWRP and boot the system
At that point I was able to boot the stock firmware with TWRP installed and I was able to restart the phone normally.
5. Flashed LOS and nano GAPPS
Now everything seems to work properly.
Hope this will help.

Thanks. I'll give this a shot tonight. Our first attempts sound very alike.

Fastboot bootlooping after trying to flash custom ROM

Hey everyone. Tried to flash a custom ROM for the first (and maybe last time) on the Mi5s from China Stable V10.2 to Lineage OS16. I think i did everything correctly at first
Unlocked the bootloader with Mi Unlock, put the SDK tools into ADB folder, flashed TWRP with command prompt, made a backup, wiped data, disabled force encryption, MAGISK root, flashed Mi5s firmware (although I could only find Oreo), LOS16 (Pie), and OpenGApps
I did all of that and got stuck on the LOS boot animation. Then I wiped data + cache partitions and tried again (didn't work). I quit trying with LOS but instead tried to flash the MIUI Global Stable recovery ROM with TWRP, also only made it to the boot animation. I then did a factory wipe on TWRP and tried to restore my backup but now it would only boot to the fastboot (not even trying to load the ROM)....... I can still access TWRP so maybe I'm not so screwed but what do I do? I just want a functioning device and don't mind if I go back to China Stable although advice on trying to flash a custom ROM would be appreciated. Thanks!

I need help!!

I was trying to install custom rom (evolution X 4.6) on my redmi note 8 pro and it went a little bad
I started off normal by unlocking the bootloader and flashing TWRP then I closed avb 2.0 and installed root and everything was fine and my phone was booting normally so then I went TWRP and wiped the default wipe then i clicked install and flashed the rom and so then i clicked reboot and i was greeted with a bootloop and i don't know what to do i tried flashing global MIUI 12 but when it tries to boot it ends up opening TWRP i also made the big mistake of not backing up my device before attempting to flash custom rom someone please help I'm trying to rollback to the factory firmware but i don't know how
i just found out you had to be android 9 to flash custom roms
now I can't even enter twrp and I tried reflashing it and I still can't enter it the only thing I can do rn is enter fastboot
NVM i fixed it using mitoolv2 www .xiaomitool.com/V2/
