L19 Problems during rollback

Hi, first time posting here, forgive me if I'm doing something wrong...
I flashed Nougat beta (L19C432B322), regretted it, and now wanting to go back to EMUI 4.1.1 (before flashing, I was on L19C20B150). Trying to follow the steps for the Huawei official rollback package, but problem is I can't even get the intermediate package (C900B300) to work through dload method... update always fails at 5%.
I am unable to relock my bootloader using the SRK tool. The error I get is "remote: root type is risk".
My phone has never been rooted.
Any help would be greatly appreciated!!
Edit: Tried to flash L19C636B168 full rom using dload method. Now bootloader is locked, but no rom is installed, booting always gives erecovery. Unable to flash any recovery via fastboot.

Bootloop Issue P7-L10

Hi guys, I'm completely newbie in Adroid stuff, and need help to get back my phone.
My software:
ROM Versio: V100R001C00B133SP01
EMUI: 2.3
KitKat​[/INDENT]
So, what I did before:
Unlock boot loader
Installed TWRP 2.8
Installed Kingo Root
Got rooted
Installed Super SU​
My issue:
Following the article, posted on this thread link, I got some some errors, then I tried by myself extract boot, cust, system and recovery from Huawei Extractor for ROM: Sophia-L10_V100R001C00B621_Firmware_West%20European%20Region_Others_Android%204-2 and ran the following commands using ADB:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
fastboot flash system system.img​
After doing this, my phone got in boot loop, I did some search here, and found a force recovery method (putting B133 ROM on SD root directory DLOAD folder and tried force update without sucess.
Does anyone any suggestion to get my phone back?
By the way, my final gola is got Lollipop or Marshmallow working on this phone if it can be alive again
Thank you,
Ivan

Reset to stock

Hi guys. I have few questions for you and would be happy and very grateful if you could answer and help me. First of all i have huawei P10 lite which i have bootloader unlocked it, installed twrp and also rooted. I also made backup of the stock rom with twrp. Now i want to restore my phone as new, i mean i want to get back to the stock rom which i made it with recovering but now how can i delete twrp and then lock bootloader? I saw that i have to use img file to delete twrp recovery - The model number is WAS-LX1 and the build number is WAS-LX1C432B124. I wasn't able to find this firmware and i am stuck now. Can i use other firmware for the model number WAS-LX1 or i will brick my phone? How to resolve this issue? I want to get back to stock.. Please help me..
Also is there any way to turn off the warning that says that the bootloader is unlocked and the device can not be trusted or just hide it? I tried to flash logo.bin file but it didn't work for me.
Thanks a lot guys.
Install recovery image from another firmware for WAS-LX1C432.
You can relock bootloader via fastboot using your code and the proper comand. This would get rid-off warning screen. All the info of firmware and oem info must coincide. Otherwise system won't boot unless you unlock the bootloader again.

Please help unbrick my phone

I have bricked my phone after Magisk install fail.
I first unlocked bootloader succesfully
then i installed twrp succesfully
then i flashed magisk using twrp - this failed and sent device to erecovery. (which won't find package)
i used twrp to wipe data, now i was able to boot, and it installed like a fresh EMUI. However, almost all apps were broken- could not download themes/camera shut down etc.
To fix this, i wanted to restore to stock and did the following: download update package for my VTR-L09 of EMUI b175 (I was on b162 before), used Huawei Update Extractor to extract files and flashed BOOT.IMG, SYSTEM.IMG and RECOVERY.IMG. This was done without error.
Now my phone won't boot at all. I am stuck at the 'your device can't be trusted' screen. I cannot go into recovery. When I connect via USB, I hear the chime in Windows but I can't seem to connect with ADB.
What to do now?? Am I hard-bricked? I hope that anyone knows how to deal with my phone bricked like this. Please help me to solve this issue.
Best of wishes.
Edit: I am able to enter forced recovery, however updates fail at 5%.
I am also able to fastboot with USB, however I am unsure what to do next.
I unbricked my phone! Many thanks to who ah way and his solution found here: https://forum.xda-developers.com/p10/how-to/guide-unbricking-p10-using-hwota-windows-t3714416
:victory:
why are you doing it when you dont understand it?
You cannot flash part of B175 firmwar eover B162 firmware.. OMG.
use the HWOTa to go back to stock and please stop playing with the device without propper knowledge
