It worked !! 
Yes !! It worked like a charm !
Almost f-ed up my bootloader with being on the 1906.19 version , but luckily i flashed then to 1907.33, before unlocking the bootloader. But NOW the OTA update from the ASUS website, the latest 1910.35 just got updated ! Everything working good. I hope in this version the "bluetooth problem" i had was fixed. I had a problem with bluetooth connecting to my car through Android Auto / or just normally. It kept connecting/disconnecting every 3-5 seconds, till i resetted Wifi/Bluetooth/Gps settings. Will reply if it's fixed, in case anyone else had a problem like me. Thanks very much again for the tutorial.
