Rooting Nokia 3.2: This is not a comprehensive guide! DO NOT FOLLOW! Will update if this becomes a proven and complete method of rooting for me.

Here are the steps that I took in trying to root a Nokia 3.2 device. However, because of the problems that process created, I had to reverse the process and thankfully get to a working state.

Unlocking the bootloader. This involves doing some setting changes and running some adb commands. What I didn’t read in instructions was that this ERASES the whole device! So, back up first!
Installing Magisk. This requires a boot image compatible with your device. I didn’t find an image for Android 11 so used one for Android 10. That created issues: Wifi didn’t work and there was no sound.
Tried flashing an image for Android 11 from SD Card and using adb sideload. both failed because verification failed
Tried flashing TWRP for Nokia 3.2, (command: adb flash recovery twrp-xxx.img) but it failed. Gemini suggested it might be case that the recovery image is installed in boot partition. I tried “adb flash boot twrp-xxx.img” and like a miracle, the flash succeeded. Then the device booted up and sound and Wifi were good again.
