Hellow everyone.

After i have a lot trouble connect the phone correctly and do unlock, i finally managed to unlock.

the instructions in the software they are not clear enough.
Here is what you exactly need to do:

first of all there are some modems (like XXUBMGA) that not support unlock so you need to doungrade the modem to XXUAMDC with this file.

that make sure that the unlock will work.

Then to the next steps:

Connect phone to the box with the micro UART cable. (c3300k)
Restart the phone (very important)
Dial *#7284# and choose MODEM.
Dial *#9090# and choose [4]DM over UART. (THis step is not necessary, but you can do it anyway.)
Press unlock.

It's very important keep the phone connected to UART from the begening, this ensures that the *7284 will work.

Please update the instructions in the software.

btw usb debuging is also not necessary at all.

good luck.
