FIrst off many thanks to @vhercastillojr (as this thread is essentially his) and Chicken from the Vietnam telegram group for providing the RAW's/img's
********** DO THIS AT YOUR OWN RISK!!! I am not liable to any damage if you accidentally brick your device. This will void your warranty, if you had one. Also, using this method you won't be able to revert back to CN roms, lock your bootloader again and recieve OTAs, your device will be blacklisted by Asus ************
NOTE: To check your current fingerprint, download and install device info HW from the playstore. Under 'system' you'll find the current rom (CN or WW), the product id and fingerprint - they all need to match to be able to update your device later
NOTE 2: The main guide below skips early roms straight to last Android 9 for ROG II. For one user it didn't work and they had to use the previous, unedited guide which was based on 1910.35 RAW. If the below guide fails to update follow the additional guide at the end of this post.
----------
0) Download the ROG phone unlock tool and copy it on your phone and install it then run it. The phone will boot twice. DO NOT PRESS POWER TO STOP THE BOOT. It will wipe your data automatically. This will unlock your bootloader. EDIT: NEWER VERSION OF THE TOOL CAN BE FOUND here
NOTE: this will void your warranty, if you had one, with Asus, even if you re-lock your bootloader later... (Although, having bought mine as an import from China, I'm think the warranty only stands with the seller - in my case, 1 year, not Asus - but i may be wrong)
1) Download the WW International RAW rom from here
2) Extract the file on your PC. Boot the phone into fastboot mode (hold volume up then press and hold power button, Fastboot mode is the 1st screen you come across, the one with the options to Start, boot to recovery, etc...) connect to the side port and run "flashall_AFT.cmd" wait for it to finish and the phone will restart itself (it will take a number of minutes to complete, with the cmd window open all the time. If the cmd window only flashes up and closes down, then check the rest of the notes with this step).
NOTE: you need to remove or delete the original zip from the raw folder once extracted as it confuses the Flashall_AFT.cmd with the raw rom and zip having the same name. Also, it can help to extract to the root of C drive.
3) Download and install Minimal ADB and Fastboot app (windows). Install it on your PC to root of C drive
4) Download the rootww191064.img and place it in the Minimal ADB and Fastboot Folder (C:\Program Files (x86)\Minimal ADB and Fastboot) from here
5) Run Minimal ADB and Fastboot by double clicking ''cmd-here.exe''. Switch the phone into fastboot mode (hold volume up then press and hold power button) then type "fastboot flash boot rootww191064.img" without quotation marks
NOTE: you can also check your device is recognised in fastboot mode by the pc/laptop by running ''fastboot devices'' cmd which should show your device serial
6) Reboot the phone and connect it to PC, copy and install Magisk and Root Explorer
Magisk
root explorer
-run magisk, (update if necessary) and grant access to root explorer (after opening root explorer you should be prompted by magisk to gain root access, click 'allow')
7) Open the Root Explorer App on you phone. Then from the app, select Mount R/W to R/O. Search for "/vendor/factory" folder and Edit the file content COUNTRY from CN to WW (ALL Capital). Scroll to "/system/etc/AsusTheme/themes" then delete the hidden file to enable the hidden themes.
8) Restart the Phone. You are done. Check again with device info HW that your fingerprint has indeed been successfully changed.
From here, if you want to be on latest Android 10, download version 2004.60 from here (full zip), place it in root of internal storage and reboot. That'll bring you to A10.
NOTE: For those of you that are rooted: Download the full zip, move to root of internal storage and reboot. System will detect and prompt to update, click update. Wait until it finishes but DON'T click 'restart', instead, click 'restart later'. Go to Magisk manager. Click 'install' for Magisk. Click the last option 'install to inactive slot after OTA'. Click confirm force flash. Reboot when prompted. Done - root kept intact.
Repeat the process for latest (currently 2012.65) using the same link above. Your phone should hopefully skip the other versions and be straight to latest. If not, you'll have to go through 2007.27, 2009.49 and finally to current latest 2012.65. Repeat the process mentioned above for keeping root if so desired
----------
For anyone still running early roms that 1910.64 won't flash directly to, use the same guide above but with the following corrections:
2) Follow the exact same instructions but using this 1910.35 RAW
4) Download root and stock boot img's and extract them to Minimal ADB and Fastboot Folder (C:\Program Files (x86)\Minimal ADB and Fastboot)
5) Run Minimal ADB and Fastboot by double clicking ''cmd-here.exe''. Switch the phone into fastboot mode (hold volume up then press and hold power button) then type "fastboot flash boot rootww191035.img" without quotation marks
NOTE: you can also check your device is recognised in fastboot mode by the pc/laptop by running ''fastboot devices'' cmd which should show your device serial
After doing the ammended steps above for 1910.35, follow the rest of the guide to change fingerprint, then update to 1910.64 zip, place it in root of internal storage and reboot.
NOTE: For those of you that are rooted: Download the full zip, move to root of internal storage and reboot. System will detect and prompt to update, click update. Wait until it finishes but DON'T click 'restart', instead, click 'restart later'. Go to Magisk manager. Click 'install' for Magisk. Click the last option 'install to inactive slot after OTA'. Click confirm force flash. Reboot when prompted. Done - root kept intact.
