Oh fucking Huawei.
Fuck you.
Inventory:
- Honor 6x (BLN-L22C675)
- Has EMUI4.1 Marshmallow
- Cousin brother 'A' (has bricking XP!)
- Uncle 'K'
- Has Mac with Windows VM
Goal:
- Stock as LineageOS / AOSP

Procedure (fucking seriously):
- Find XDA link to root H6X
- Go to Huawei page and fill out form
- Receive and use bootloader code
- Find latest TWRP
- Flash latest TWRP
- TWRP not working? Bootloops
- XDA search "H6X boot to recovery"
- Find and try modded TWRP
- TWRP fails, no bootloop
- Find & flash TWRP 3.1.0
- Yay! TWRP works
- Find and download LineageOS and SuperSU
- Flash via TWRP
- Yay! Success.
- Attempt boot
- Boot fails. No idea why
- Go back to TWRP
- TWRP gives shitload of errors
"cannot mount /data, storage etc."
- Feel fucked up
- Notice that userdata partition exists,
but FSTAB doesn't take
- Remembers SuperSU modded boot
image and FSTABS!
- Fuck SuperSU
- Attempt to mod boot image
- Doesn't work (modded successfully
but no change)
- Discover Huawei DLOAD
Installer for "UPDATE.APP" OTAs
Note: Each full OTA is 2+ GB zipped
- Find, download, fail on 4+ OTAs
- Discover "UPDATE.APP Extractor"
Runs on Windows
Note: UPDATE.APP custom format
Different per H6X model
- Uses 'K''s VM to test
- My H6X model does not have
a predefined format
- Process to get format requires
TWRP, which is not working
- FAIL HERE
- Discover "Firmware Finder"
Windows app to find Huawei
firmwares
- Tries 'K''s VM
- Fails with 1 OTA
- Downloads another firmware ZIP
- Unzips and tries to use OTA

- Downloads, flashes TWRP
- TWRP not working AGAIN?
- Go back to XDA page
- Find that TWRP on EMUI 5 - NO
- Find rollbacks for EMUI5 -> EMUI4
- Test, fail 2-4 times (Massive OTAs)
- DLOAD accepts this one?!!!
- I HAVE ORIG AGAIN!!!
- Re-unlock and reflash TWRP
- Realise that ROMs aren't working on
EMUI 4.1; Find TWRPs for EMUI5
- Find and fail with 2-3 OTAs
Note: Had removed old OTAs for
space on Chromebook (32GB)
- In anger, flash one with TWRP
instead of DLOAD (which checks
compatability)
- Works! Same wasn't working with
DLOAD
- Find and flash a custom TWRP
as old one still exists (not wiped in
flash)
- Try flashing LineageOS
- LineageOS stuck in boot
- Try flashing AOSP
- Same
- Try flashing Resurruction Remix
- Same
- Realise that need stock EMUI5
vendor
- Realise that the firmware I installed
wasn't for my device so not working
- FUCK NO MORE LARGE DLs
- Try another custom TWRP
- Begin getting '/cust mounting' errs
- Try reflashing EMUI5 with TWRP
- Doesn't work
- Try DLOADing EMUI5
- Like before, incompatability
- DLOAD EMUI4
- Reunlock and reflash TWRP
- WRITE THIS AS A BREAK

Me: *pulls down the quick settings drawer and taps Bluetooth*
phone: *forgets everything about having multiple CPU cores and threads - the process responsible for all user input and drawing the ui grinds to a halt*
me: *sighs* oh, fuck, not this shit again *sets phone down*
*several minutes pass*
*watchdog decides that the UI is stuck and kills it, forcing the phone to soft-reboot*
phone: *boots up after a minute of loading*
me: *checks if Bluetooth is on*
*Bluetooth still off*
me: *tries to tap Bluetooth again*
*the procedure repeats*
