Problem to dowgrade Mate 8 Nougat to Marshmallow - Mate 8 Q&A, Help & Troubleshooting

Hi everyody i have some problem with my phone NXT-AL10.
I've made an update to a NOUGAT Beta version for my Mate 8 but for somes reasons i need to downgrade my phone to the emui 4.0 (or 4.1 i don't remember my old version) but the problem is here. Last month i tried all version of TWRP but any version worked for my device with Android 7.0. Now i've found TWRP Version 3.0.2 or 3.03 and i can boot to TWRP but it always said it can't mount system ! (I've tried to format DATA, all wipe) but nothing works !
I tried the DLOAD method but the same i tried 15 UPDATE.APP and i can't flash my phone.
Now my phone have just access to TWRP but without the possibility to mount system and when i tried normal boot i go always to the eRecovery but i can't use UPDATE.APP. I have one choice "Download latest version and recovery" off course it doesn't work !
I'm stuck at this state can you help ?

Says so right there.. The ota zip youre trying to flash is meant to update KRT16M build (which is KitKat), to some newer build (doesn't matter which one).
You need to use the ota zip to update LRX21O, not KRT16M.
Simple. How hard can this be.

[HELP !] Unbrick honor6X BLL-L22

Hello, everyone
I need your help
I was trying to rebrand my BLL-L22 (which was working fine) to BLN-AL20C00
(To upgrade to Oreo)
so since Bootloader unlocking isn't working anymore , I followed this Thread :
[GUIDE]Unbrick honor6X. (No boot. No fastboot. No Recovery. No bootloader code)
the process was easy and clear
but something is messing I guess
I reach the point where my phone phone start working as factory mode
I restart to fastboot and flash the OEM by this code :
Code:
fastboot flash oeminfo BLN-AL20C00
and it's done successfully
then I restart the phone
then I put the UPDATE.APP (of this version: BLN-AL20C00B172) in dload folder
and do the normal dload method , but it doesn't work (says: please insert otg/sd card or check app files in 2 mins)
I think this is because the firmware is differnt from the factory mode system
...
I tried many things like installing TWRP , trying to flash the Update.app contents by fastboot :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
and still nothing works
..................
I even installed my original oeminfo (BLL-L22C636)
and trying to flash all my firware versions : B150 , B360 , B391 , B396
and alllllll didn't work
...................
so I need to undersatnd why my phone doesn't accept any normal dload files and what can I do ???
I'm even begining to suspect that HL2BLNTMBD001051 isn't compatible with my phone !
but if you are sure that it is the right one , tell me what can I do after reaching the factory mode stage
because my phone doesn't accept dloading anything
​
look at the photo attached
this is when I try to install the Update.app contents by fastboot
(after I restart from this stage , the phone do bootloop , so I start over and try something else)

Bad TWRP, boot Stuck, ̶ ̶n̶o̶ ̶a̶d̶b̶, Can't flash new rom! Help!!

Bootloader is unlocked.
TWRP 2.8.7.0 for 4.4 ( mobopx v2.2 ) is installed but somehow it is faulty.
I have two Nandroid Backups.
Phone was C00B137 4.4.2.
Phone doesn't boot so can't install any of those (UPDATE.APP) method updates. Stuck on huawei Ascend powered by android.
i CAN boot into twrp and fastboot (fastboot&rescue) .
TWRP backup works so i got two backup first one right after flashing the custom recovery, and another after everything wipe and an unsuccessful android 6 flash (B571) (phone booted into a clean 4.4.2 (what it was on) but empty motion control setting. and "update from usb storage" button removed from updater's app (the only way it installed that unsuccessful android 6 update ).
So, What was the dumb move?
That shouldn't happen.. when i selected everything to wipe, after that. Yeah. That's enough go read the rest.
.
.
.
What is it? What are you waiting for?
Why can't install any rom:
1- TWRP Restore does not work (does not find the backup).
TWRP ADB Sideload Probably doesn't work (i connect to pc then click the adb sideload, infinite loading until i cancel on phone. no device detected on windows).
2- Worst part : SD Card Does NOT get detected in TWRP.
The only way to transfer files to phone is through USB Storage (Otg).
3- As mentioned before, all complete updates are .app files. With This TWRP, only zip files can be installed (Which are just as suffix to the os, all are 100 mb, 300, 700mb, what is this? humans update is 1.2GB up to 2.2GB and more.) the TWRP Install works as i tried to install one of those zip update files, obviously unsucessfull (Zip signature Failed or something like this).
References:
The B571 rom i installed (that was finished but after reboot it was still 4.4.2 with bugs) is C432B571 Full OTA( Europe ) from this page.
The Twrp i used is Recovery mate7 mobopx v2.2 update and translate by chudy_85 on same page. number 7:

the adb i use is shift right clicking on platform-tools folder -> open command prompt here. learnt from here. also unlocked boot loader according to that (although with help of honortuner ( https://forum.xda-developers.com/t/info-unlock-bootloader-recovery-root-noob-friendly.3453204/ ) ).
UPDATE:
1--This is the log of when i unlocked bootloader:
2-- ADB WORKED! At least in recovery (not that sideload button in advanced) :
What should i do now? how to flash UPDATE.APP through adb??
Should i first flash stock recovery then through huawei update (key combination) update using sd card The update.APP????????????????
but i will lose custom recovery so if it fail i will truly brick the phone this time. HELP!
no help for me?

Unable to update oxygenOS after unbricking

So I have become member of the bricked-my-phone family. I have followed this tutorial https://www.getdroidtips.com/unbrick-oneplus-6/ and successfully unbricked it.
I have downloaded latest oxygen os (I tried two latest - one with android 11 and one with android 10), I have added the zip to the root directory and from system update I selected it, but in both cases I instantly get "System update installation failed" at 0%. It also says I am up do date from OTA (it it android 8.1 lol)
what should I do?
I want to install latest oxygenOS only for firmware, then I will be installing LineageOS again. I am afraid If I do it the other way around (LOS first than firmware) I will brick it again.

That's exactly what I did and the result, you see on screenshot..
But later in the evening, I found the solution here https://forums.oneplus.com/threads/oneplus-6-system-update-installation-is-failed.1314311/:
The OP6 must be on 9.0.9 before upgrading to Android 10.
You are still on Oreo/Android 8.
There is a link for 9.0.9 on this website:

If you are able to boot to Fastboot as well as able to unlock bootloader than do unlock the bootloader and flash this msm file
[ROM][STOCK][FASTBOOT][OP6] Stock Fastboot ROMs for OnePlus 6
Things are changing with the advent of project treble and seamless updates. OnePlus will no longer release ROMs flashable via stock recovery (with twrp is possible but not recommended). The updates will be done on the slot not used for example...
forum.xda-developers.com
And after that reboot to recovery stock and factory reset. This will fix your issue than after lock the bootloader(if it's unlock after flashing the file) and update to latest rom (download the rom from oneplus updater app with advance setting "on")
