I recently installed the latest PE 12 on my Moto Z3 Play (XT1929-4)...Besides the headache of an install, I eventually got the rom installed and noticed a couple things having issues if anyone has any idea:
- Settings app crashing when trying to select "SIMs" or "WiFi"
- This one is a big issue since I rely on WiFi with this phone entirely and I can't switch the WiFi networks right now
- Moto Mods Projector seems to crash often when using the software button
- Seems to work fine when using the hardware button
- Ensured I was on stock rom Android 9 (phone came with 8)
- Flashed PE 12 recovery
- Format then sideload `copy-partitions-20210323_1922.zip`
- Format then sideload retrofit `aosp_beckham-ota-retrofit-eng.aicp-dev_2.zip`
- Restart to System
- It booted PE 12...now I am thinking it may have been already installed from previous attempts...but the procedure says to sideload the PE build after retrofit is installed and "Format your data and reboot to recovery.", but this step would "brick" my device and I would either have to install the stock rom again or somehow get the fastboot working again
