K770i Unlock Inactive Sim

I have flashed the mbn, fbn, tpa and relative vkp with jdflasher, everything went fine. Now all sims put in the phone come up as "inactive sim" but they will tell you what network the sim card is on. What is the problem here? The SIMs work in other phones.

Would really appreciate help

are you saying that jdflasher doesn't work for applying unlock patches?

use setool to apply patches, works for me

i followed everything exactly on setool to unlock and I get

Going to execute VKP script....

PHONE IS RED RETAIL PRODUCT
FLASH CID detected:52
Speed:921600
Trying to launch embedded bootloader...
embedded flashloader not responds !

thanks for your help, is there anything that i could try?

im afraid you damaged your gdfs.. bricked.. sorry bro...

TRY WRITING YOUR GDFS...
PUT YOUR GDFS BACKUP IN MISC FILES AND PRESS WRITE GDFS...

hope you backed up your gdfs

first thing to do, A BACK UP

If you don't have backed up your GDFS you can still fix your phone imo:
