UNLOCK HUAWEI DEVICES RUNNING EMUI 8 JUNE PATCH OR LOWER
You can upgrade to EMUI 9.1 and have unlock bootloader too, but in order to do that you will need set a custom code which will be later in the guide
!!!!! NOTE: IF YOU HAVE KIRIN 990/970/980/710/810 THIS WILL BRICK THE DEVICE INSTEAD SO IF YOU HAVE THAT SOC PLEASE DO NOT TRY !!!!!!!
If you're device is on EMUI 9.1 you will have to downgrade to 8, to downgrade use hisuite but if you do not get "Switch To Older Version" button, Downgrade to an older EMUI 9.1 build, to downgrade you will need a micro sd card, download the firmware from androidhost.ru and extract the firmware then go to the folder named "Software" you should see a dload folder, copy that onto your sd card, then slot it onto your device, to flash the firmware, power off your phone, press and hold all 3 keys then a firmware should be installing, if you get incompatibilty with current version error, thats becuase you can't downgrade to EMUI 8 just yet, once u installed an older version of EMUI 9.1 , it is time to downgrade to EMUI 8, go to hisuite select update, then once it detects a new update click on older version, select that and it should begin the process of downgrading to EMUI 8, however you are still not done with downgrading, you need to flash a patch that is june 2018 or lower, flash ANE-LX1 8.0.0.144C432 which you can find on androidhost.ru, same method, once you have finally downgraded, its time to request a slock to flash TWRP, to request a slock please go to the

First flash the NVME.ZIP in order to do that you will need to flash it 4 times due to safety, if twrp reboots, you have done it successfully, then flash the custom bootloader file, reboot the device
THE DEVICE IS NOW UNLOCKED
BUT

you will need too, download HUAWEI Update Extractor
https://forum.xda-developers.com/showthread.php?t=2433454
then extract the update_sd inside the dload folder, inside the EMUI 8 Firmware, you should see an UPDATE.APP extract that using "Huawei Update Extractor" then get the ERECOVERY_RAMDISK using the program, then get the .img one and reboot into fastboot mode, do fastboot flash erecovery_ramdisk ERECOVERY_RAMDIS.img and flash TWRP onto RECOVERY_RAMDISK, now its time to update to EMUI 9.1 and unlock the bootloader using the code we changed too, we can use dload method, or update using settings, once we have that you're bootloader will be now unlocked, and to unlock it do fastboot oem unlock TishSerg_For4pda select yes on the device and the device will now factory reset
