1. Try it at your own risk
2.before you flash it, backup your TA first, you can use Backup TA or flashtool 'Advanced->Trim Area->Backup'
3.You need to use my modified version flashtool to flash it
4.flash modified baseband ftf and reboot will get it work
5.SO-02E can not flash this ftf. If you flashed will LOST SINGLE, if you did not backup your TA can use this fix to restore single.
This change is permanent, you only need to flash it once.
c6602's LTE possible work with band 1 5 8, because of different power amplifier IC other bands may not work or work poor .
The pcb is same but power amplifier chip in the left area is different
If you want to restore baseband configuration, you can restore TA first and flash the baseband file but exclude TA.
in NV/TA-log, I found first time init baseband, it will read all item from TA partition 1, such as rfnv files, and baseband config
by writing to TA I have successfully switched baseband configuration from W1358 (WCDMA band 1 2 5 8) to L1357_20W1358 (LTE band 1 3 5 7 20 and WCDMA 1 3 5 8)
but still have a lot of data from TA partition 1 difference, such as rfnv files, so I need more TA S1 Dump to determine which data affect the baseband configuration
here is a modified version flashtool based on flashtool 0.9.18.5 version, which can fast dump all TA data include TA partition 1 and 2
click File -> Switch pro to enable Advanced menu
click Advanced -> Trim Area -> S1 Dump to dump ta, them reboot phone to flashmode
