[Q] Please help me fix my issue

Hi.

My phone is not bricked, but I stuck with a "test build" rom on my phone, I have no idea how to install anything else now.
First of all, I have to tell: I previously always used telephones with stock android interface, so this is why I wanted to mess with my phone, and try some other rom (for example: carbon), emui wasn't so friendly for me...

I had fully stock P10 lite dual sim version with 3gb ram WAS-LX1C432B206 (or maybe an ota update newer) when I opened up the bootloader.
Installed twrp_p10_lite_0.4.img from fastboot, and installed supersu on the phone. With the stock rom and root was everything working well.
The only thing, I noticed, the TWRP did not see normall the data partition, if i wanted to browse, i just saw directories with strange caracters in their names.

One week later i wanted to try Carbon rom. The next problem came up here, I wanted to back up my system and data from twrp, Of course the data partition always was failed. I tried different twrp versions what I have find here on XDA

- EliteTWRP-3.2.1-0_2018-01-19.img
- Huawei P10 Lite-RecoveryTwrp EMUI 8.0.0.zip
- Twrp P10 Lite Nougat By KingOfMezi.zip
...and different versions of these twrp recoveries..

Elite and KingOfMezi twrp version was working the best for me, however also not good with the data partition. Because of this i made no backup from my data partition. (honestly nothing important on my phone yet) These recoveries allowed me to Format data, then wipe dalvik, cache, data etc..
So on this way i was able to install another rom, with no any error messagesm but with no any luck...

Any Rom I tried with no emui, was failing to boot, even not starting the boot sequence..
After this I flashed Elite_Rom_v7.7_for_P9-Lite_Honor_5C_6X_8-Lite_10-Lite_by_HassanMirza01
which was booting up, but my simcard was not working in the phone..

I fixed this problem by flashing and Huawei P10 Lite-OemInfoC432DualSim.zip and using 3 button method with dload folder on an empty sdcard with update_WAS-L21_hw_eu.app and update.app (Warsaw-L21_C432B182_EU_SERVICE_androidhost.ru)

After this, Android boots up, everything works fine, simcards too, imei numbers are okay. but the build version is NRD90M test-keys (and a year old version of emui rom)

It also closes back the bootloader, which i can open up any time, and flash twrp again, almost any version i want, some of them gives me error messagesm like not enough space on the pertition(sorry i dont remember exactly for the massage) espacially when i want to flash recovery ramdisk, always fails... With the flashable twrps the old problem still presistant with the data partition: i can't read/mount. Or after a restart, i can mount, and format, but no matters what i try to flash on the phone, nothing boots up.

If i use the 3 button method, and the sd card, the phone sets back itself to this test build rom, and works just fine, But i even can't install supersu on this system because it makes fail to boot...

I thought i'm technical enough to root a phone and install some different roms just like before in the previous few years, but i screwed up something very much, and honestly i already don't understand the whole methods, i dont see thel logic behind the procedures, I lost the clue...

In my opinion the main problem must be around the data partition because its not visible from the twrp recoveries...

If anyone have any Idea how to fix my issue, i appreciate, and thanks in advance.

if the rom number version is test keys you did the step oeminfo bad, copied more or insufficient files than you need and boom the restore made incorrectly.

Obviously make a copy to the important data qnd enable oem unlock.

1- you need a sdcard, ds orr ss oeminfo and b182 or 183 depending on your system
2- insert sdcard on the phone slot and boot in twrp backup only oeminfo(copy to safe place before nothing) then replace oeminfo, restore and dont make anything more.
3- Copy b182 or b183 service rom files inside of dload folder to dload created in sdcard. 182 for ds, 183 for ss.
4- finished copy seitch the phone disconnect the microusb from phone and just do the dload method.

Hey! I have a P10 Lite WAS-LX3 dual sim. I was trying to flash a custom ROM with android Pie, I have a lot of experience doing it with a lot of cellphones, but this time I don't know what is not working, I did a complete clean installation like you did in the first part of you tread, the problem is that the Custom ROMs don't boot I tried a lot of them also tried lineageOS 15.1 just like it happened to you, the only one that works is stock ROM, When I flash the Custom ROM without errors then I reboot to system, but, I cannot pass the screen of: You device is booting now. I really want use customs ROM in my cellphone, to give to it another year. Thank you.
