D750i Unlock + Flash

[nemesis202]

This morning I tried to unlock and flash a D750i with W800i firmware. First, Cruiser asked me to do unlock RSA before flashing. I tried to unlock RSA function and it never worked stating that there was something wrong with the GDFS. Repeated attempts ended up with the same result.

I tried the unlock function to calculate the codes on the phone and after a few seconds it gave me an entire list of unlock and relock codes for the phone. I entered in the NCK value for the NETWORK, and the code was incorrect! I carefully reentered the NCK code and it was incorrect once more.

Next, I used a Total MultiServer credit to unlock the phone. Worked fine without needing any unlock RSA function. Another credit went towards flashing the D750i with W800i firmware. At the end both unlock and flash went properly without any errors.. with TMS. It's a shame I had to use two credits for something that should have worked with a standalone Cruiser Pro.

I have never had any problems servicing K750i phones with Cruiser as all functions seemed to work very well thus far. Unlock RSA first is still a tedious task I would be happy to get rid of.

EDIT: I did some more searching and read that changing the certificate to BROWN and then using DIRECT UNLOCK should solve the problem I had. So there's no need to use TMS when encountering this problem with a D750i. This will teach me to research a little more before coming to an ultimate conclusion. Sorry for the misinformation.
