Well i dunno how well installing a mod and trying to flash the tsop is going to work for u, in my opinion that's a waste of time to try to flash the tsop if u've already got a mod installed....can someone tell me what the point of that is?
Anyway, there is no version specific tutorial needed for using raincoat/exploiting gamesaves...it's all the same for all the versions besides 1.6 of course...
The only thing with tsop flashing that varies from 1.0-1.5 is the unlock pads u have to bridge to be able to flash the tsop, which i wanted to ask ya, have u checked, double and triple checked with a meter?
Put it like this, if u got a good non-corrupted gamesave on ur mem card, put it on ur xbox's hdd, run the game, exploit in, telnet, IT WILL FLASH THE TSOP, considering u got the unlock points correct and all...
BTW which brand tsop do u have in ur box?
