to figure this stuff out, i used losetup —partscan to process the partition table of a complete flash image i took using mtkclient i’m now using that partition map to recover my old userdata partition and reflash it to get everything back how it was, maybe. this could restimulate the brick i dunno. looks like it may take like half an.hour. i’m using phhusson treble_experimentations v414 and it’s looking much better than v415 already — for example it reports strong LTE service which I didn’t have before. i’ve also learned there is a “treble app” which can fix connection issues, and also some other workarounds to configure in the phone settings for e.g. bluetooth to be more reliable. 927cdc11519965df75007bdafdf1b6b2eaf459b4803fa5538bda910acd0dc3cdc34388bd4c748acb1969548bab424c978648eaed5b791f201f44842a32490b34 v414-2022-11-05-system-squeak-arm32_binder64-ab-vanilla.img
