recommendations before upgrading le2127 to Android 12?
I've heard horror stories about Android 12s roll out. I'm afraid I'm gonna lose everything or have a expensive paperweight that won't even be able to operate while being multiple months behind on sec...
As mentioned, don't update currently. If anything, wait for Android 13, which should be available in October. If you update, you will not be able to roll back without losing everything. The only way I would recommend using to roll back, is with the MSM Tool, which can be found in the XDA forum for your device or on the OnePlus forums for your device.
The learning curve for using the MSM Tool isn't very friendly. You will need to boot Windows with Driver Signing Enforcement disabled, install unsigned drivers in Windows multiple times, be familiar with Device Manager and manually choosing drivers, and use a tool that if interrupted for any reason before it completes, will hard brick your device.
