Sorry just wanted to verify something I am currently on beta 3 with the Canadian CSC flashed. To upgrade to version 4 I have to downgrade to US pie but when I do revert back to pie will my my phone factory reset? Also I'll assuming US pie would be using Odin and installing all 4 files again correct. Thanks
Reverting to the US One UI V1.0 (Pie) Yes You Flash all four tar files with Patched Odin & I always Factory Reset after Reverting back to the US One UI V1.0 & then YES - You need to Flash from Recovery - (apply from sd) each of the One UI Beta v2.0 zips until you end with ZSK9 - Then Flash the Canadian CSC with Odin..
I Always Boot the device after Flashing each zip in Recovery BTW 🐧
