I had the same issue but have now managed to restore my previous version (1.5) by using the Wipe/Format Data option in TWRP before pushing & installing the old v1.5 zip (I also had trouble doing that initially).Hello,
i was using a older version and have yesterday installed the 'iode-3.1-20220726-cepheus.zip'. Now the phone won't boot into os. Only into recovery. I can not mount anything as it can not find the cryppto footer and can't mount data. I want to restore the twrp backup but it is not there. How do i get my old system back?
However I still haven't worked out how to install v3.0 or above. Could there be a similar issue to on this thread or is that just specific to Samsung? I am still on TWRP v18.104.22.168-mauronofrio. Do I need to upgrade this too before/after moving to iode v3?
