I want to go from Lineage back to FP OS with closed bootloader. I understood the whole manual, except for the following important sentence at the end:
Quote: “If you install an OS with an older security patch level than your previous OS, Android’s roll-back protection might brick your device when locking the bootloader! Wait until you get a software update with the same or newer security patch level before locking the bootloader.”
My question: At this late stage, the previous operating system that was on it is already history, isn’t it? Another question: Does it only depend on the security patch level, or also on the Android version, because that would be a downgrade from 13 to 12.
Greetings Martin
