You need to use the FullOTA-MF file. what was the last version on your phone?Hey thank you, i followed the link to your guide, but i'm stuck on choosing the right package
my model is KIW-L21 (that's what's written in the back of the phone)
when i search for that i get 3 option that are FullOTA, but i don't know which one i'm supposed to use?
looking forward for your answer ^^
