Facing issue while updating to android 12 ..
what file do, you want to flash?
Sounds to me that you are trying to install 12 DP1 right? If yes, are you aware that it's not even at open beta level and is older than your current OS version?
Do you have any link for 12 DP1
I think it Dp 4 , do you have link of 1
Here is the official thread for it:
what OxygenOS version are you currently using?
What have you downloaded and where from?
I have android 11, 22.214.171.124
This DP is older,..
If you want to flash it, you first have to downgrade to an older official OS version
OxygenOS 12 for the OnePlus 9 and OnePlus 9 Pro
