So i tried flashing a leaked firmware of the 4.4 Touchwiz rom for my i9505. All fine, i pass the setup page using wifi. However when i disable my wifi my phone doesnt connect to my carrier EE(Tmobile uk) and when I goto mobile networks, it doesnt detect my sim card, i get "insert sim card"
Now i have gone back to 4.3, currently using Golden eye rom...i recommend this rom. However when trying a later leak of 4.4 by Wanam im still having the same issue. I have searched and searched and no one is having this issue...so far. I have update BL for 4.4
My concern is that the day samsung finally release an official 4.4, my phone wont work. Any one with a solution?
