My iphone 4 is not showing the version
i tried to upgrade my jailbroken iphone 4 from ios 5.1.1 baseband 4.12.01 to ios 6.1.3, while upgrading i faced many errors 4014, 3004, (11), few more errors and finally restored the ios to 6.1.3 with custom .ipsw using itunes. After upgrading, my iphone is still in version ios 5.1.1, but when i check in Settings> General>About> version shows N/A. Tried factory reset, after the reset was completed, the iphone still shows version N/A.
Redsn0w shows my iphone 4 (unknown FW, 04.12.01), while tinyumbrella shows iPhone4 6.1(10B144).
How to solve this issue?
