Its finally happened. Thanks to the brilliant work of the DVRFlash team its now possible to crossflash your 212D to the 212. The files you will need are located here:
http://rapidshare.de/files/38802385/...flash.rar.html
The above file contains DVRFlash 2.5, the kernel, and firmware for the 212. The firmware installed will be 1.22. From there you can flash to with the latest pioneer official firmware which is 1.24. The DVRFlash command to run is:
dvrflash.exe -ff D: S0013000.122 S0013001.122
Say yes to the warnings and the flashing will then proceed. After which you reboot and you will be at 212 with be firmware 1.22 installed. Take note the command above assumes your drive is D so change as necessary. The kernel for the drive came from Pioneer China which supplied the kernel with this firmware. Thanks!
