I tested provided Android 8.1 image but it needed format+download all. Then returned to provided Android 6 image (and format+download).
Android 8.1 is missing sounds and have older kernel.

Now android 6 is show only 3G network, wlan is not functional blank screen easilly, missing IMEI. How get + restore factory calibrations? What partition holds them?
