Spoiler: Installing base EMUI 8 for hi6250 devices.

This was already described in a separate thread which describes the process to get back to EMUI 8 from custom ROMs. You can find it here.

Just follow the procedure in that thread. You need not even flash the frp unlock thing. After that, follow the process described in this thread.

It's recommended to be on original EMUI 8 before installing base EMUI 8 for hi6250. Follow the process linked in requirements to install EMUI 8 first then follow this spoiler.

Procedure :

• Make sure your device is running stock EMUI 8.
• Extract downloaded image using some xz extractor(7zip can also do this), copy it to pc.
• Reboot your device to TWRP.
• Format the data partition {Wipe > Format data > type "yes"}
• Flash fstab.hi6250b.zip from attachments
• Check if your device is detected by adb using

  adb devices

  .
• Move the img file using adb to device

  adb push -p *img-name*.img /sdcard/

  (the img file must be in adb directory).
• (Optional, only if you want gapps) Move Gapps in the same manner

  adb push -p *gapps-name*.zip /sdcard/

  (the zip file must be in adb directory).
• Install img as system image {Install > Install Image > Select > Choose system image > Swipe➡}.
• (Optional, only if you want gapps) Unmount and Remount system partition as writable. Go to wipe > advanced wipe > Choose system > resize > Swipe➡.
• Flash gapps.
• Flash stock recovery. Push it with adb using

  adb push -p stock_recovery_ramdisk.img /sdcard/

  and flash it with twrp as "Recovery" after choosing install image.
• Disconnect your device from PC and reboot to recovery(stock one).
• Clear cache partition and perform a factory reset(You'll get an error during factory reset but you have to do it) (your device will bootloop if wiped with twrp itself).
• Reboot, Cross your fingers and wait.

>Booting is quite different in android 11 ROMs on our device. You'll see the "Your device has been unlocked" screen for more time than usual. Then, you'll see the boot animation (for very short time on subsequent boots) and the device will boot to ROM. So, be patient. (This isn't the case with ROMs upto android 10)

>Face Unlock is working perfectly

Spoiler: Additionals

Additionals:
>Its better to charge your device to atleast 70% before doing anything as you'll have ample of time to recover it if you messed up something. If not, you can still charge your device in eRecovery mode and twrp but i found some issues like heating up and slow charging.
>Don't forget to set ringtone, notification and other sounds from settings after booting.

Happy Flashing !

Thx for keep looking for the best andorid 11 rom for Honor 6X. Installed it, no issue so far, testing it as a 2nd daily device. Let you know...

Below is my installation procedure using a microsdcard, quite the same as post #1 apart of that.

- on a micro SD card, download:

https://forum.xda-developers.com/attachments/twrp-img.5326857/

https://sourceforge.net/projects/darkjoker360-developements/files/Huawei/fstab.hi6250b.zip/download

https://forum.xda-developers.com/attachments/stock_recovery_ramdisk-img.5321325

FluidOS-1.1-Rum-R-Hi6250-emui8.img extracted with 7zip from https://mega.nz/#!jWQWEJ7Z!cd2S5oy2g8IdUuw5PfQEkSadslojBpFgB6ltUNOpc-w

OPTIONAL: pico gapps from https://sourceforge.net/projects/opengapps/files/arm64/test/20210110/


- insert the micro SD card in your usb debugging enabled Honor 6X (with EMUI 8 or custom rom installed over EMUI8), and connect it to a PC with adb & fastboot


- in adb, "adb reboot bootloader"


- in fastboot, "fastboot flash recovery_ramdisk TWRP.img"


- in fastboot, "fastboot reboot"


- after reboot completed, "adb reboot recovery"


- disconnect the honor 6x from the PC


- in TWRP recovery, Format the data partition {Wipe > Format data > type "yes"}


- in TWRP recovery, flash fstab.hi6250b.zip


- in TWRP Recovery, flash FluidOS-1.1-Rum-R-Hi6250-emui8.img {Install > Install Image > Select > Choose system image > Swipe}


- OPTIONNAL IF GAPPS WANTED: in TWRP recovery, Mount system partition (Mount > check system and unckeck read only OR reboot in recovery).And

resize system (Go to wipe > advanced wipe > Choose system > repair > resize). Then install open_gapps-arm64-11.0-pico-XXXXXXX.zip.


- in TWRP Recovery Flash STOCK_RECOVERY_RAMDISK.img {Install > Install Image > Select > Choose recovery image > Swipe}


- in TWRP recovery, reboot to recovery (even if TWRP says no OS installed)


- in Stock recovery, wipe cache and factory reset (error is normal)


- in Stock recovery, reboot and wait

Same with me.

Hello, do you know how can I factory reset in the Huawei ERecovery step at the end ?
I try to do it so but it keep reboot my phone to TWRP recovery, it's like I can't wipe data/factory reset my phone from the stock recovery.
Maybe TWRP is bloking it ? Should I disable something in the TWRP settings ?

Between thanks for yours work !

Your mistake is that your using stock erecovery.

You have to use stock recovery. Meaning flashing the stock recovery provided in post 1 over the twrp recovery :



- in TWRP Recovery Flash STOCK_RECOVERY_RAMDISK.img {Install > Install Image > Select > Choose recovery image > Swipe}


- in TWRP recovery, reboot to recovery (even if TWRP says no OS installed)


- in Stock recovery, wipe cache and factory reset (error is normal)


- in Stock recovery, reboot and wait

 

[Kentoto2021]

Yep thanks, I forget to choose Recovery when I flash the stock recovery ramdisk, so my twrp install it on the last choice that it's system image

To resolve my problem I reinstall my previous system (EMUI 8 for honor 6x) and this time I wipe the david cache, system, cache ... after format the data partition
And I didn't install any OpenGAPPS and it works fine !
A little empty, but I will try without Google services to see if it sweet to me, it saved a lot of battery so that's nice !

Again, I thank you all of you for your amazing work thank you very much my honor 6x can still live haha

Edit : no it's too painfull without google services haha

Perform a factory reset after flashing gapps too.

Flashing gapps without factory reset crashed chromium based browsers on AOSP 10. This might not be the case with this rom but better do it.

Android without Google services is more and more easy.

Aurora market is a good choice.

I have also some workaround for'GPS localisation and so....

Nevertheless, gapps working fine for me, no device lag cause of it ! All services active and working

Same with me. And the power menu controls are just AWESOME.

Dang, I cannot go past installing Huawei USB COM driver to unlock my device (

? Didn't get you... Did you mean bootloader unlock? If yes, follow @lmaohelp 's guide mentioned in post 1. He described it very clearly.

Yes, it's clear, read the posts, watched YT video, but one of the steps is installing Huawei USB COM driver to replace the SER driver, and I already tried on 2 computers, Windows 10 (updated) fails to install that driver, and without it, PotatoNV won't 'see' the device.

Oooh how did you get that ?
I only have this :

Is it Gapps ? I use the nano one

 

[Venkata Lochan Nune]

Nope, there's an app on play store called "power menu controls" download that. And the other, you could use Tasker(also an app from play store) to create your custom controls like the ones I did for screen rotation.

what's the procedure you followed to install drivers?

Unzip the attached file, and choose "DriverSetup.exe" and that's it. uninstall these drivers after installing the rom using "DriverUninstall.exe" for mtp to work. The process will ask for reboot in some language(i think Chinese) after uninstalling but it isn't needed.

*These are also the fastboot drivers(but the name in attachments is testpoint drivers).

Indeed! I once tried using AOSP 10 with floss services and without Google ones but yeah it didn't last even a day... lol I flashed gapps within 5 hrs.

Thanks a million! It worked., I just unlocked the bootloader, I did not have these drivers.
Now onto next steps... may take a while, I'm old and slow

Well, did not go too far... when trying to flash twrp (as per this guide:

), I'm getting an error:
fastboot flash recovery_ramdisk twrp.img
target reported max download size of 471859200 bytes
sending 'recovery_ramdisk' (24466 KB)...
OKAY [ 0.642s]
writing 'recovery_ramdisk'...
FAILED (remote: partition length get error)
finished.

Ideas?

P.S. I also tried
fastboot flash recovery twrp.img
target reported max download size of 471859200 bytes
sending 'recovery' (24466 KB)...
OKAY [ 0.642s]
writing 'recovery'...
FAILED (remote: image verification error)
