What I did notice is that the P725AV1.0.0B13.zip is the one that you have to install in order to root according to the post.
I need you need to go back and re-read that post...
NOTE : Make sure you have updated your Tureis to the latest firmware version (BP_P725AV1.0.0B06), check the STOCK ROMS thread
However once flashed the BP_P725AV1.0.0B06.zip didn't show the right baseband/firmare needed to root as per the original instructions. It was the OB13.zip that showed OB02 but it is also Android 2.2 and not 2.3.5. What I was going to try was to use that image and then root with the updated superoneclick, but got bricked before getting the chance.
Stock ROMS are named after their internal version, not the display version, so while the display might show B02, its internal version is B06.
From the sound of it you've installed Android 2.2 and then a insecure 2.3.5 boot partion.... not going to be pretty.
What you can try to do is make sure the 2.3.5 stockrom is on your SDcard, unzipped into to image directory, take our your battery, count to 15, put it back in and turn your device on holding down vol+ and vol- ... and hope for the best..
