Just to test try flashing any of the custom firmware in 4.1 framework . See if the network registers . If it does then ur flashing a wrong version of stock .
Hi, it seems that I was able to find solution. As I've been on 4.3 official rom it seems that EFS partitions were modified and when I flashed stock 4.1.1 it seems that the modem can't access info on this partition. So I flashed modem from official 4.1.2 firmware and everything started to work. This thing was mentioned somewhere on this forum.
But here comes my another problem
When I flashed to 4.1.1 I saw knox warranty void 0x1
But it was too late when I saw what this does mean
But the problem is that download mode says that my phone is in custom state and that I loaded custom firmware 1 time. Well... I've tried to root the phone, installed triangle away and tried to reset flash counter. When I entered download mode I saw that flash counter was set to 0 and that the phone is in official state. But when I rebooted phone till Android OS and went to download mode after that I saw that flash counter was set to 1 again but the phone is in official state. Why is that? I have stock recovery and stock rom. As I've read there must be no such thing. Could it be because my bootloader is from 4.3 version? And one more thing - I was not able to enter recovery mode when I rooted the phone
Phone stays at the flash screen forever
Is it expected thing with stock recovery?
And one more question. Lets imagine that I have 4.1.1 official rom, I'm rooted and want to flash 4.1.2 official rom with odin. Do I need to unroot my phone at first or can I skip this step? Thanks.
