Hello. I have GALAXY S5 - SM-G900F Lollipop. I wanted to root it and i used Kingo. It said that root was successful i even had superSU app, but i couldn't open it and when i installed app that i know needs root access i didn't get prompted to allow it. So after some checking i concluded that root was not successful and wanted to revert it with kingo again. It said that S5 was not rooted and i couldn't root it again (was getting failed this time). Then i wanted to do factory reset to 4.4.2 via mobile but each time i would select that option phone would just freeze. I booted into recovery TWRP that i installed previously and did hard wipe. After that i was without ROM, and installed lollipop using this tutorial (/watch?v=r_ifFnj9tbo). Everything was fine but i lost TWRP and was with stock recovery. I wanted to root phone again using different method (/watch?v=iBNGeppOzGI) but when i installed TWRP via odin (i got success and phone rebooted as last time i installed it) but when i try to boot into TWRP using button combinations phone just loads standard recovery. I also tried to install CWM, same results. Success message, phone reboots and it still loads stock recovery so i'm stuck now. Anyone has any idea how to install TWRP now?
