KT2 Bad Data CRC can't get kernel image

[suppl]

Hi, I'm new. I have read for the past few days.
I've got a defective Kindle (7th Gen) (WP63GW) (KT2, I believe?) from my mom, so no one has tampered with it before me.

I have soldered wires to the serial port and got it running to this point:

(It seems like the firmware is newer than Jun 29 2019, which version would that be?)

If i try booting into diag with "bootm 0xE41000" i get the same error.
I have also tried deactivating the verification with "setenv verify no", but then it just says "starting kernel" and does nothing else.

"bist fastboot" seems to set it to fastboot and dmesg under ubuntu shows me the following:

[13811.193755] usb 1-4.4: new high-speed USB device number 22 using ehci-pci
[13811.314705] usb 1-4.4: New USB device found, idVendor=1949, idProduct=d0e0

[13811.314716] usb 1-4.4: Manufacturer: Amazon
[13811.314719] usb 1-4.4: SerialNumber: 062060___

but it doesnt show up as a fastboot device.
It also does not show up in files, so i cant put update files on the device

Any help would be appreciated, but i suspect that the storage chip has failed. (or is this the version of uboot with a faulty crc calculation?)

As you might tell, i am no expert with uboot

Thanks

Oh, and I've built a little dev-y board out of the kindle (added the buttons and glued on a uart bridge) I might desolder the shields if i have to access the storage chip.
