Thanks for providing a easy way to backup emmc. But the files make me confused.
Cuz the fastboot can flash (without userdata) : bootloader, prod, bist, mrb, kernel,diags_kernel,system,diags.
And the script provides : boot0.bin, boot1.bin, diagkern.bin,diagsys.bin,diag-uImage, localsys.bin, main-config.gz, mainkern.bin, mainsys.bin, main-uImage, prefix.bin.
By "fdisk -l", eMMC 4.x shows 4 partition and mmcblk0p1 for mainsys.bin, mmcblk0p2 for diagsys.bin, mmcblk0p3 for userConfig and mmcblk0p4 for userData.
Also, boot0 and boot1 didn't shows in "fdisk -l". it seems that Boot prod and bist are located in boot0.
Therefore, if i start to flash my kindle voyage with an empty emmc. How to do i t?
I read some materials and made a conclusion:
1. Use MfgTools to download u-boot.bin into kindle's ram.
2. Enter the fastboot mode to flash diagkern.bin, diagsys.bin, mainkern.bin, mainsys.bin,.
3. Reboot Enter diags to dd boot0.bin and boot1.bin back to their place in emmc.
4.Debrick done
Am i right ?
