Develop Bugs

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.

[Q] Stuck without recovery

Hello,
I'm sorry if this is a retype of a thread but i didn't found one. I've searched far and wide with no success.
Before i dig into the unbricking thread and reinstalling everything i just wanted to ask if this happend to anyone and if there is a simple solution for it.
I have zenfone 2 551ml with ressurection remix Remix nougat 7.1.2_r2
The phone is still working but i have no recovery. One day (dont ask me why) i wanted to update twrp just by flashing another twrp image in the twrp recovery. It didnt get updated but after i rebooted the phone, the next time there was no more recovery. I tried to flash it via fastboot with fastboot flash recovery command but still nothing. The device is detected both in adb and in fastboot.
Any ideas?
Thank you

I solved it
The thing is that i had to flash the stock recovery. Than i could sideload stock rom and now i continue.

[SOLVED] HELP! i'm stuck in a boot loop! :(

my flashing history:
i was on audax (oos based nougat rom) with blu spark kernel before, then went to official ob1, then back to audax, then back to stock oos nougat and now i flashed audax and after clean flashing it, it just wont boot up.
when i try to boot up i see the 1+ logo but then it reboots to recovery. i also tried flashing stock nougat again and also flashed stock kernel manually but it also doesnt work.
i always do:
1. wipe system/dalvic/cache/data
2. install ROM
3. wipe dalvik/cache
4. flash magisk (also tried without flashing magisk)
5. reboot
i've been looking on the interwebs all day but nothing worked.. help pls :/
EDIT: problem was blu spark twrp. Maybe installing Oreo ****ed it up. I flashed codeworkx newest twrp universal build and now Im able to boot again!! Btw: I also found that magisk 15.0 prohibits a proper boot up and results in a boot loop. version 15.2, however, does the trick!

when it auto reboot to recovery, formate data

When s**t happens, it is wise to start everything from scratch:
-boot in fastboot mode and flash stock recovery with "fastboot flash recovery recovery.img" (rename recovery.img with your recovery filename), then reboot recovery and select english, advanced, adb sideload;
-flash stock OS with "adb sideload rom.zip" (rename rom.zip with your Oxygen OS filename).
Procedure will require some minute because of the large file size. Remember to save all your data on internal storage first!
I advice you to flash original recovery because often sideloading in TWRP leads to some error.
Your phone will boot again... after that you may reflash TWRP, Magisk etc

I had the same issue. Bootloop and jumb into recovery by itself. You have to flash magisk 15.2 via recovery and will be boot.

He says that it occurs even without Magisk... I had a similar trouble once, and the only way to solve it was the procedure I wrote above...

I dont know if you can boot it w/o root

Why not? Stock OS is not rooted.

He said audrax not stock oos

SOLVED! TWRP was the only variable left that I didn't think of. See initial post for solution. thx for help!

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!

Problems with recovery.

After the firmware Lineage 18.0 flew recovery, stupidly stopped opening.Flashing through adb recovery img does not give anything, can someone tell me something? Now I can't restore the TWRP backup or flash the custom firmware and Magisk.

I installed the service firmware via the computer and everything worked out.

In my case i boot on fastboot and flashed twrp img without booting into Lineage OS 18.1 and i could install another rom, Lineage OS 18.1 sadly has the bug that deletes TWRP recovery on rom boot, doesn't matter if you install again TWRP recovery
