Hi @aibd,
I mean I can’t login to TWRP screen using easy installer after the download. I’m in HK and got that EMEA exynos S9+ SM-965F. I don’t know if it’s becoz of the regional lock as you mentioned. I don’t RMM State at all.
But I did get into the TWRP screen once when I followed the steps in the below link for old phone, of course with update img / tar files for S9+:
However, I noticed I forgot to downloaded the /e/ zip file for S9+ at that time and I chose to reboot it to the system.
When I compared the /e/ installation for old model SM-J500FN with the updated instruction for command line installation for S9+ (https://doc.e.foundation/devices/star2lte/install), I found that I needed to install a custom recovery by heimdall. But this step was not shown in the installation guide for SM-J500FN. So my questions are:
-
Can I just follow the old installation guide for SM-J500FN but with the update files for S9+?
-
I notice the difference on “wipe” the data on the phone. Should we follow the memory wiping guidelines of SM-J500FN for S9+ as below?
-
If I wipe away all the data but fail on the installation in the end, will I still be able to reboot back to system? Is the disc image file “recovery-e-0.23-q-20220406175186-dev-star2lte” the same as the Samsung ROM file downloaded from sammobile site? The Samsung ROM file for S9+ is missing on the sammobile site.
-
Is the command line installation the only way to install /e/ OS on S9+?
Thanks so much for your assistance and patience.
