Just tell me how to downgrade ZC553KL Oreo to Nougat. I did try some nougat firmwares listed on support site :
- UL-ASUS_X00DD-WW-14.0200.1705.202-user.zip
- UL-ASUS_X00DD-WW-14.0200.1710.336-user.zip
- UL-ASUS_X00DD-WW-14.0200.1806.355-user.zip
None of them working, wasting alot of time to download those useless firmwares.
So tell me which one is working. Thanks
