BC it was kickin my ass too... i finally figured it out and got it to work
you just need to make sure the android info text file is the same version than the current mainversion of your firmware. technically it could be higher, but you dont want to do that,as it will change it on your phone to that higher number,hindering the process for future flashes
for example,if youre on 2.01.605.11,your android info cant be 1.02.605.6. ive found the hard way that the wrong android info does not return an error,just disregaurds the update
i finally got recovery,system and boot images to flash in hboot. yay!
it is possible to edit the mainversion number,so you can flash older recovery,boot and system images. doing so,however,will
not let you downgrade whole ruus to get an older hboot and radio. youre still stuck with those
should be able to "fastboot flash zip" PH98IMG files too,but i havent gotten to play with that after getting a handle on the main version thing.
