Phone: ROG Phone 5 (ZS673KS) - not Rooted
Firmware: WW-31.0810.1226.154 [downgraded from WW-33.0210.0210.200]
SN: M2AIKN064236Z87, [actually in service RMA: PLB4R62262 but I'll get it back in few days]
Main problem is that system (WW/EU/RU) can't upgrade to Android 13 (WW-33.0210.0210.200) from WW-31.0810.1226.154 using manual or automatic update methods - when system see update file in main directory it will ask to update, if I select Yes it always fail.
From version WW-31.0810.1226.146 (A12) i've upgraded to WW-33.0210.0210.200 (A13) without any problems or warrings.
From that reason is in subject "downgrade ... to version WW-31.0810.1226.146", and after that I can finally update to A13
Alternate solution of problem could be way to upgrade directly from WW-31...154 to WW-33...200 - i think it's easer way.
If ASUS employees acually working of solution of this problem or new version of android 13 please give me a message.
Or if now it's dangerous to upgrade system to A13 WW-33.0210.0210.200 please let me known.
Thank you for reading message and any help.
This was the rational and well-founded assumption I made based on my research. If it works let me know.
