ok, so i've decided to do something with the turd tablet i bought, now that my htc flyer (which i am very satisfied about) does what i want it to (i.e. making giant phone calls). maybe i can turn this woow! tab 7 rockchip 2818 tablet into a shiny turd, which of course is a lot better than a not so shiny turd. - used z4root to get temp root - installed superuser.apk, su.apk - pushed/copied rkdump onto the sdcard - could not copy rkdump to /data because there is no 'cp' command - could not move rkdump to /data with 'mv' because it gives a cross-device link error - so i used 'dd' to copy it (dd if=/sdcard/rkdump of=/data/rkdump) - used rkdump to dump boot,system,recovery,kernel to the sdcard and here's where i get stuck. rkdump doesn't want to dump backup (mtdblock5) or misc (mtdblock0) block device, it gives and error: unknown image (00 00 00 00). i tried to use dd to dump it to the sdcard, but the file was getting bigger and bigger, so i stopped it when it reached 1.5gb. can't be good. and no idea how i'd use that image to flash the device again. without a proper backup.img i am of course not going to try and flash something onto the device, because it's still a $180 non shiny turd. woow! digital are asshats, i've mailed asking for an image to reflash my device, but they never answered. which was to be expected after exepriencing their customer support first hand for fixing battery drain, hangs and re-experiencing it again after they 'fixed' it and borked the sdcard reader. so that's a dead end. so, does anyone know of a way to make a backup of the backup partition? i've searched the net, but to no avail. there was one post somewhere where someone managed to dump it with rkdump after it failed, but didn't explain how or why. i'm on linux, but can boot to windows to get things done. any help would be appreciated.
