ok not tested yet as i am already rooted . but i pulled every single file from my device including boot images and kernels everything that is in the .57 build.every single file but from a .56 system. replaced all files in the signed .57 update with that of .56 so basically created a .56 update zip. any takers wanna try see if it will let you roll back from .57 to .56. of the image should already be rooted as well. my self and androidtablets.net take no responsibility if you brick your device. if it grows wings. or if it racks up internation charges calling 1900 numbers. directions ok so if someone will test attemp 2. let me know. rppr what about using adb. adb push zImage /sdcard/zImage adb shell dd if=/dev/block/mmcblk0p8 of=/dev/block/zImage adb push /dev/block/mmcblk0p1 of=/dev/block/ramdisk.img adb push /dev/block/mmcblk0p6 of=/dev/block/u.boot.bin adb push /dev/block/mmcblk0p12 of=/dev/block/sm0 http://www.mediafire.com/?wybpyca329qdldp is the 4 files someone try with adb.
