Can't get olipro 2.40

[mommasboy]

Ok heres the problem, the internet on my phone was acting up and customer service couldn't help me, they told me to take it to a store for repair. I was running NEX's mutant rom and the phone was unlocked so I thought it would be best for me to lock the phone back and install an officail rom. Everything went fine, I locked the phone and put 2.17 on it. I tried the internet and it was working. I figured the problem was fixed so i tried to unlock the phone and reflash back to a custom rom. On my first try I flashed 3.35 from 2.17 and noticed that my Bootloader number was 2.0. I tried to flash a custom and it didn't work. So next I figured it didn't work because i didn't unlock it. Once I unlocked it my bootloader went back to 1.20. Next I tried to install olipro's 2.40 and it starts to install, but then I get an error 260. I disabled activesync and that didn't work either. I can get 3.35 back, but I love the custom roms that u guys provide. Can anybody help me, i don't k now what to do next.
