Problem after flashing my k770..

I flashed my R8AC001-based k770 to unlock it, using a R8BA024 firmware for the flash... everything worked out fine, I applied the patch and the phone now accepts any SIM card. However I can't seem to call or send text messages anymore. What is the problem? I thought you could let the phone run on any firmware ??

Thanks in advance.

Did you use the right cust pack?

First of all u need to flash MAIN and FS of the same region and cid, together with the appropriate custpack.

If you have done successfully, try to do master reset.

P.S. IMHO, cust pack only affects languages and nothing more. It's unlikely to influence the possibility to call and send sms

maybe your firmware and cust pack doesn't match?

I think is the "network lock"!
Other way,I'm chinese! so my English just so so!
