Just want to share. I have a rooted  and custom fw samsung s4 4.4 jelly bean and the software status is CUSTOM so i cant update. Also knox=1 so ive read in many forums that you need to reset the counter of knox so you can go back to official rom and update the system.

I tried deleting data/dalvik/system and reboot after, so there is NO OS. I downloaded odin for pc and samsung drivers for pc and the samsung s4 official lollipop here https://galaxys4root.com/international-galaxy-s4-stock-firmwares-gt-i9500/

 

Then followed instruction also in that site how to flash via odin and poop it become coco crunch! My software status is official and i updated the system 2x successfully.

 

I just thought that going back to official fw status and system update is impossible when the system knox is =1. So now i can play in fb messenger words with friends LOL

Ayos to, salamat po <3

ayos to ah

Yun!!!! Salamat po

nice. thanks for sharing! 

Bago nyo delete ang system make sure  while sa odin mode (power+home+volume down) at odin pc nadedetect ang samsung nyo.

ok paba to? e try koto maya
