KT3 Missing partitions

[hermit1]

Hi,

I got a KT3 serial number begins G000K9.
Probably MMC was erased.
I could partly reflash it with diagkern.bin and mainkern.bin no more files was flahed (thanks for description). Now the partitions are missing and kernel freezes. Is there a description about partitions or utility how I should create them or the whole process (serial port connection is working, these recovery menus didn't help:
I. Initialize Partition Table (fdisk) and format FAT
O. Format and overwrite FAT partition)?

Does the version of recovery-util on your device give you the option of exporting the userstore partition? If it does, download an update package for your device, transfer it over USB and reboot the device - this should take care of the main partition.

You can grab a copy of the diags partition from here: https://www.mobileread.com/forums/sh...d.php?t=342535

The diags partition can be installed by flashing it over fastboot.

I'm quite newby in Kindle "word".
How can I access recovery-util?
Usb_diags ( uboot_2009-08-lab126_wario_usb_diags.bin) or diag image ( kt3-078-b7-diags_eanab_heisenberg-301630.tar.xz) is needed?
"transfer it over USB" means copy the diag image simple the Kindle internal storage or via fastboot (/fastboot flash diags_kernel diags_kernel.img)?

I could start.

Details:
I created 4 partition in linux:

Spoiler:

fdisk -l

Disk /dev/mmcblk0: 3959 MB, 3959422976 bytes
4 heads, 16 sectors/track, 120832 cylinders
Units = cylinders of 64 * 512 = 32768 bytes

Device Boot Start End Blocks Id System
/dev/mmcblk0p1 * 1025 15424 460800 83 Linux
/dev/mmcblk0p2 15425 17472 65536 83 Linux
/dev/mmcblk0p3 17473 19520 65536 83 Linux
/dev/mmcblk0p4 19521 119296 3192832 b Win95 FAT32

Disk /dev/mmcblk0boot0: 2 MB, 2097152 bytes
4 heads, 16 sectors/track, 64 cylinders
Units = cylinders of 64 * 512 = 32768 bytes

Then mmcblk0p4 partition set 0b type and format with mkfs.vfat.
Mount it and copy to update_kindle_8th_5.15.1.1.bin on it then unmount.
Reboot kindle, finds the update and configure all.

Hope it helps.

Something still not properly set at partitions just 53MB free: https://ibb.co/DgjDTCQ

partitions are the following: https://ibb.co/Dr0k6tC

All of them are showing in Windows at connecting device. Of course only the b type partition accessible under Win, but the copied e-book are not showing because something still wrong.
"Kindle Internal Storage" should be shown. Any idea?

Try a factory reset. If this does not help, once again in the recovery menu, initialize the partitions and format the FAT partition.

Thanks Eddie, factory reset solved it!
