I have try to change imei in my lg u250.

String for HyperTerminal is :

AT%RIMEI= "IMEI1234567...."

Imei of the phone is changed, but when phone restart, there is on display : UNAVAILABLE OTP

I flash phone and originale NV , but "UNAVAILABLE OTP" don't change.

If i try to re-wright imei with

AT%RIMEI= "ORIGINAL_IMEI"

don't work and prog give me an error.

Any Ideas ??

Simply now you have to rewrite the memory area as original... No other possible solutions there. The error means that OTP block is no longer found inside memory area.
I suggest not to use AT commands without knowing how to do it, especially IMEI one.
