Can anyone please help, i keep getting this when i try to relock the bootloader.

Slot _a is unbootable
Were you still rooted with the root boot img? What rom version are you running? You could try flashing the corresponding stock boot img for your rom...

I got this when I used the 1908 root img. I would suggest using the 1907 raw image to do the changing of fingerprint.

1) Download the WW International rom from here

https: //tinyurl.com/y5yq6sfk

2) Extract the file on your PC. Boot the phone into fastboot mode (hold volume up then press and hold power button) connect to the side port and run "flashall_AFT.cmd" wait for it to finish and the phone will restart itself.

3) 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.

4) Download and install Minimal ADB and Fastboot app (windows). Install it on your PC.

5) Download the rootww190733.img and save it to the Miniman ADB and Fastboot Folder (C:\Program Files (x86) \Minimal ADB and Fastboot)

https: //tinyurl.com/y5xs4wam

6) Run Minimal ADB and Fastboot. Switch the phone into fastboot mode (hold volume up then press and hold power button) then type "fastboot flash boot rootww190733.img"

i did step 1 - 6, the problem is... i download room ww 1908... should ww 1907 because step no 6 its rootww1907...I didn't check again.
i flash boot with rootww19033.img on rom 1908. im scare and I know I made a mistake. and The big problem i jump to this step 3) While on fastboot mode and ADB, Relock the bootloader and run "fastboot oem asus-csc_lk"
BOOM!!!!!!! after that my phone restart and have notice "Slot _a is unbootable"
im confuse and scare my phone i think broke... T_T
after that i do it again from the begining,

In the same shoes, I'm not sure if I have to follow since step 1 or start on step 3.
Actually I'm curious, is there any downside on having 'device is not certified' on your google play? Does it effect any daily use? Thanks.

Personally, I don't want to change my rom version but just want to update all the apps securely. In that case, do I need to change my fingerprint version? Because in Play store it said 'device is not certified'. Thanks.

You need to follow each of the main steps to change to WW and the final steps too if you don't want to keep root

OK, so you've tried flashing other roms, that didn't work.. But you say you were last running 1908.12 before all this happened. I can only suggest flashing raw 1908.12 rom... I'm uploading a version now and will post links when it's done. Extract the zip file to the root of C drive, remove the original zip from that same folder (as it has almost the same name as the raw rom which confuses the flashall_AFT.cmd). Put phone in fastboot mode, run flashall_AFT.cmd. I'll provide a link once it has uploaded. Let me know when this step has been done and if it boots OK...
HERE IS 1908.12 raw rom... HERE
