Kindle backup

[bole5]

Any chance to get this script updated to support PW4?

[NiLuJe]

Unless someone with a PW4 volunteers, highly unlikely.

I don't even rightly recall if it supports the Androidized layout *at all*, to begin with.

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 ?

It does not. I tried to analyse the file system and backup partitions. I came acros some weird things. Please see below for details but interesting was:
- fstab should mount /dev/mmcblk0p1 to the / but this device does not exist!
- fdisk does not dump partitions correctly (produces an error)

My system is a brand new kindle PW4, jailbroken, with custom 5.10.1.3 firmware, never connected to the internet.

Please let me know if I can help...

Kind regards

Hello.Does this backup works on a KT4 kindle 3 (2019) 10th gen kids edition jailbreaked?

[Kindleschokolade]

Hello and thanks for the great tool.

I was wondering what tool I'd need to mount the bin files?
Would like to poke around a bit inside.

Cheers!

[j.p.s]

I've never used this script, but it looks like it uses dd to copy each emmc partition.

Have you tried the mount command?

Maybe fdisk first to have a look around?

[Kindleschokolade]

I am on MacOS currently. Might have to look into a VM with Linux for that.

[Hightree]

Any advise how to backup system partitions of Paperwhite 5 (gen 11)?

What devices are relevant to physical partitions?
Thank you.

[Kindleschokolade]

Hello,
is it actually possible to write on backup back to another kindle so as to basically clone it?
Thanks!
