Samsung Galaxy S4 i9505 IMEI repair done! Guide inside 100% working fine

1. USB debuging on
2. Root manualy with CF-Auto-root (flashed via ODIN in PDA section)
3. *#7284# - set "UART" to PDA (Default is PDA)
4. *#0808# - set "USB" to AP (Default is AP) ,,,, set "USB settings" to DM+MODEM+ADB (Default is MTP)
5. *#9090# - select "[4]DM over UART(*)" ,,,, phone will reboot.
6. Connect phone with usb (install drivers if needed)
7. Select box comport in z3x
8. Repair button in z3x, fill IMEI.

Phone will check for root, write data, then it will reboot. After reboot connect phone with c3300k microUART rj45 cable (if its stuck on "Checking phone at COMxx..." then quickly *#9090# - "DM over UART", u should have enough time to reboot phone while z3x still searching on comport). z3x will write IMEI and reboot phone. All done!. Phone may search for network little bit longer but it will sign into network after while (max 2mins).

I was experiencing some troubles to get 3G working properly. However, after flash of firmware and wipe data and cache afterwards everything works as it should, expect that phone is searching for network one minute, max two (WEIRD).
