Lg U250 and UNAVAILABLE OTP error

[AirSac]

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 ??:confused:

Now IMEI *000000000000000

[AirSac]

Yes.
And if i use :

AT%RIMEI= 1

imei become 100000000000000

Change imei now accept only 1 number.:(

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.
