I finally goy my fun book today.. Enjoying it. But I can't backup the stock rom, there is option for restoring, but no option of backup... These are the options I'm getting... 1.reboot system now 2.apply update from external storage 3.wipe data/factory reset 4.wipe cache partition 5.apply update from cache When started by pressing Option+On , a menu comes up.. Android system recovery<3e> Android system recovery utility (EVP: vol up/vol down, home, enter) reboot system now apply update from external storage wipe data/factory reset wipe cache partition apply update from cache 3. Go to Play Store and download Superuser. 4. Go to Superuser App > Settings > Su Binary > Install the Binary 5. Reboot. I downloaded Superuser v3.0.7 (41) I went to the round icon on the upper right, then, under General, updated the Su binary v188.8.131.52. Is it that what is needed? When I'm running recovery-install.bat , its giving me 'access denied' messages(ran with admin privilege, updated drivers as instructed) adb shell "cat /data/recovery.img > /dev/block/nandg; sync" /system/bin/sh: cannot create /dev/block/nandg: Permission denied I changed permission of the /data and /dev folder manually by "Root Browser". Couldn't change permission of /dev/block/nandg . Also tried from adb shell, no permission allowed. Mayb it a problem with new funbook tablets.
