Thanks, im downloading right now

I see k120 and vs425pp have same processor and very similar phone, have you tried this on other phones?

davidreyest · 12-07-2017, 18:17

I mean, how can I know when a phone "supposed to be" only cdma can actually work GSM flashing another firmware from similar phone?

Mr_F10ch3 · 12-07-2017, 18:25

Some proof attached !

Phone have GSM bands 850/1900 also without convert to k120 it work but only with LTE simcards and only work on sms and data, can't make calls.

NOTE: i can confirm vs425pp works on H+ and vs425lpp works on LTE

Then it should work on any cdma phone that comes with sim reader?

Not all, for example LG-LS770 don't work on GSM and have sim reader.

Some phones bands/frequency involve a hardware part.

Writing phone firmware without real necessity is at your own risk.

Downgrade may lead to phone damage!

Please, make sure the phone's battery is fully charged.
Disconnect all other devices from the computer (including phones,
modems, etc.) and close all other running programs.
To avoid errors in the flashing process, use a clean PC (without any
installed drivers for other Qualcomm-based devices).
You should not run any other programs or attach new devices to your
computer during the flashing!
