After i stuck in Hboot 6.17 and cant update with OTA or root with Revolutionay. When I flash the stock rom it show that The Main version is older. So you have to downgrade it before flash the stock rom.
You have to install
android sdk and Hex editor (and relative tools)
step1 download z4root install it and use temporary root it.
step2 we get temp root now. open a cmd and input adb shell
step3 input su root(it will change the icon).
step4 copy the mtd1 file to sdcard.
input cat /dev/mtd/mtd1 > /sdcard/misc.img
step5 move the misc.img to your pc and use some hex editor to edit it.
step6 goto 11 row, you will find current version number. (in my case is 4.24.651.1)
step7 change it to 1.0.000.1 save the file. (should backup the original one)
step8 copy the flash tool and misc.img back to sdcard(flash tool:

step9 input cat /sdcard/flash_image > /data/flash_image
step10 input chmod 755 /data/flash_image
step11 /data/flash_image misc /sdcard/misc.img
Now you can flash officail KDDI PC36IMG.zip by bootloader or ruu rom.
