P9 lite VNS-L21C430 bricked - Huawei P9 Lite Questions & Answers

Hello everyone,
I have a big problem. I used my phone with Lineage OS 14.1 by meticulus, installed by twrp by meticulus.(from xda)
I was deleted every partition from twrp, because I want to install new ROM(Lineage OS 15.1 by HassanMirza)
But my phone can't install anything.
I downloaded the service ROM, and the roll back pack, reflashed for the factory recovery but nothing. Every update.app and custom ROM go to error, because invalid for this device....
Help me please, and sorry for my bad english .

(sovled)Bootloop after installing custom rom in TWRP in Z00LD HELP!!!

i had installed custom rom and recovery(lineage 14.1 & twrp)
it was working fine until the lineage updater downloaded an update and asked me to install it.
but i didnt read the instructions properly and now every time i reboot my Z00ld it gets stuck in a bootloop
how can i get out of the loop.
here are few things ive tried already:
i had a backup after installing the custom rom (the 1st time), the backup didnt work.
so i wiped the whole OS and tried to install the rom again. it completes the installation process without any errors but after completing, it just boots back to the TWRP recovery.
How am i supposed to get out of this loop.
(this happened only after the updater downloaded an update and tried to install it. )

Lineage seems to be no more available for Z00LD. I'm trying to install any custom roms on my Z00LD (I'm new on rooting and/or installing new roms) but I am not sure about which one is available for that model. Could anyone help me please? Thanks.
Regards.

Deleted OS, only twrp loading now

I was trying to install havoc os on my moto g5 plus, i rooted with magisk and unlocked the bootloader, and when i tried to flash the havoc rom it gave me error 255, i upgraded the twrp and when i rebooted to install the rom it gave me error 7
Then i tried to keep my stock rom and it just wont load, it tells me the password is correct when it loads but the data is corrupted and need to factory reset, but when i do that it just loads twrp
when i connect the phone to my pc it shows that the sd is normal but the internal storage only has the twrp folder which makes me believe i currently have no OS
please help me
You must be flashed wrong Ver of Havoc, Happened with me
Try to flash any other Custom Rom
Try some 32 bit android 7.1 ROM.. I suggest Resurrection Remix 5. I got error because twrp was not 64 bit.

Issue flashing Havoc os 3.0

Hello everyone, I'm trying to flash Havoc os 3.0 alongside with BitGaps, but it always ends up in a bootloop (I always wait one hour in the "android" boot screen). My device is the A205G with Android 10. I successfully flashed TWRP using the guide posted here in xda (also flashed magisk), then I flashed Havoc and BitGaps (wiping dalvik, cache, data and system first and then doing a factory reset), but ended up in a bootloop after rebooting to system. In a second try after reinstalling Android 10 stock rom I followed the steps shown in a youtube video (can't post link since I'm a new user) with no luck (still getting a bootloop). In a third try I just flashed the stock rom, then flashed twrp with odin and tried to flash Havoc without flashing Magisk at any moment, still bootloop. Any ideas or suggestions on what could be wrong? I've only flashed one device before with a custom rom so I'm not an expert in this area, any help will be appreciated.

Can't install any ROM.

Hi,
I used Lineage OS 17.1 Lavender on my Xiaomi Redmi Note 7. I used their recovery to install the ROM and open gapps. Recently I downloaded the Brave Browser and I wanted to enable rewards. I than googled, that Brave doesn't allow rewards on rooted phones. I decided to wipe the entire phone, since I don't use the root functionality and to re-flash Lineage OS 17.1. I factory reseted the phone and wiped everything, just like I did, when I installed Lineage for the first time. I clicked on "Yes" when prompted that the ISO couldn't be verified, and waited for the flash. After a while I was "greeted" with Updater process ended with Error 7. I did some research and found out that it is something to do with the updater file verification and that I should try and delete some lines. I did that, but the error persisted. I than decided to try another ROM. I used Pixel Experience since it was working on my device before. Unfortunatly I had no luck. Same error message. I than tried to flash TWRP with fastboot, which worked. Wiped my device, just like they say it in all the guides (Dalvik, Data, Cache) and tried to flash Lineage (still no luck), than PixelExperience (still no luck) and Magisk worked. After I flashed Magisk I tried Lineage and Pixel once again, but still the same error.
If you know, how to fix that error I will be so glad. Is it possible that my device is bricked and beyond recovery? Thank you in advance.
update your tvvrp
Which firmware do you have installed? Use stable to maximum compatibility, on some ROMs if you have latest you gonna get that error. Also, use the latest TWRP or Orange Fox.
As Tatoh said, this error occurs when you have old firmware flashed on your RN7, some roms require specific version but usually flashing latest stable will give you best compatibility, here you have xda links to latest xiaomi firmware files: https://forum.xda-developers.com/redmi-note-7/development/firmware-xiaomi-redmi-note-7-t3925871
