I need LTE bands 1, 3, 8 and 20.
Official polish KitKat 4.4.2 MPN release does not work on these frequencies.
Can anyone tell me which official KitKat 4.4.2 region release (MPN) works on those bands.
Can some one suggest me where to post a help request for 4.4.2 official KitKat, CSC radio/modem modifications?
I really need help.
I'm going crazy searching forum and websites without finding a solution.
