Hi,
First, I have no windows system (only Mint and Ubuntu) on my computers.
I tried to follow e/OS installation steps described in
- Install /e/OS on a Samsung Galaxy A5 2017 - “a5y17lte”
- install /e/ on a Samsung device from a GNU/Linux PC successfully on the forum (10/2020 post)
heimdall print-it
seems to work (phone display information and reboot).
but after heimdall flash
, I can not switch off the phone to reboot it on recovery mode and it reboot with the current system Android 8 (R16NW.1520FXXUGCTKA)
heimdall flash --RECOVERY twrp-3.7.0_9-0-a5y17lte.img --no-reboot --verbose
Heimdall v1.4.2

I saw on the TWRP documentation for A5 2017 that there may be a protection “dm-verity” preventing system modifications.
Here is the screen at the end of the heimdall flash
execution
Is there a way to solve this that I missed ? I am not used to phone “hacking” and have no windows computer to operate.
I would like (and I also need) to experiment e/OS as some important applications do not accept to run on Android 8 forcing me to change my phone which works.
Thanks for your help
