Note that I am running Mac OS X.
I tried installing an unofficial version of Cyanogenmod I found on XDA Developers that supports kltemini (SM-G800F). However, I messed up somewhere in the installation, and got a message on TWRP recovery saying:
Can't install this package on top of incompatible data. Please try another package or run a factory reset
And when I try pressing Reboot into System, I get:
No OS Installed! Are you sure you wish to reboot?
In the comments, @beeshyams said that I can install from a trusted source SamMobile, where I did get the SM-G800F Czech version, and downloaded it. However, the flashing fails with:
Error flashing zip /external_sd/Android_Stock.zip
Extracting it on a computer makes a
.tar.md5 file, and extracting that gives me a bunch of
.img files. I read that I should compress these, and flash, but the same error showed.
Another solution could be to download a custom ROM so I can actually boot into ANYTHING, but most ROMs don't support SM-G800F.
What I can also do is go to Download mode, and download stock recovery, so I can re-install the OS over OTA, however there is a risk that I will not be able to use Recovery anymore.
How can I solve this?
Trying to flash stock recovery with heimdall prints:
ERROR: Failed to send data!
Releasing device interface...
I am on OS X and I am using the CLI Heimdall to flash
