I still have my Samsung Gear S and I love it...
It's was running the latest for my area (Bulgaria) firmware - 18.104.22.168 (R750XXU2BOL2)
Recently I had some problems with empty notifications from different apps and decided to flash different firmware.
I found that in some areas the firmware is higher version - up to 22.214.171.124 for Malaysia and Ukraine.
I was able to flash successfully 126.96.36.199 Malaysia firmware - it was slightly different and very fast but draining the battery too quickly.
Then I flashed the Ukraine firmware and it was really good but the problem with the empty notifications was still there so I decided to go back to the stock Bulgarian BGL 188.8.131.52 firmware.
No problems flashing back the BGL firmware but for my surprise the watch started in German language (not Bulgarian).
Then tried UK 184.108.40.206 firmware and again the watch started in German language...
I cannot get it back to Bulgarian language - I downloaded both BGL firmware versions from this site and still the same result - the watch is starting in German - also not recognizing my sim card now...
Any idea how to fix my issue?
