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?
UPDATE:
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

Answer
Looking at the installation instructions of the ROM you flashed, I am guessing in the TWRP/ CWM options, under Advanced Wipe , one of the options " Wipe Dalvik Cache, Cache, System and Data " (likely data) was missed out leading to the current situation.
[[ Edit
Thanks to OP for confirming that wiping data was missed out by him while installing CM. A couple of other observations made by OP are listed. These are NOT normally observed behaviour of CWM but may be occurring due to incompatibilities of ROM being " unofficial"
- CM didn't start normally when data partition alone was backed up
- He had to resort to wiping data to get back to normal functioning. This is also mentioned in the installation instructions of the ROM
Flash CyanogenMod:....Note that the recovery might fail to restore the backup when you want to go back to the stock ROM (emphasis by ROM developer)
]]
That aside, as you brought out, there are two options
Option 1 Re-flash CM ROM and subsequently revert to stock if needed
Option 2 Attempt to flash stock directly
Option 1 would be preferred option since your unable to flash stock ROM and get an error message
Suggested steps for Option 1
- Boot to recovery mode of TWRP/CWM
- Wipe Dalvik Cache, Cache, and Data (inside Wipe -> Advanced Wipe for TWRP)
- Install CM ROM
- Install the GApps zip-package
- Test that ROM is correctly installed by testing minimum functionality of Google play store connecting, camera and call/ SMS working
Now,assuming it is successful,use the ROM for a couple of days before deciding if you want to continue with it or revert to stock
Reverting to Stock from CM 12
- Since you are using OS X and Debian, install Heimdall (am not conversant with it so will skip the details)
- Flash recovery. This guide seems to explain the process well but you can suggest a better alternative with your experience http://davideddu.org/blog/posts/how-to-flash-a-recovery-image-using-heimdall/
