Looking at your setup you still soldered something to the kindle itself, i did the same, only mine didn't have the jumper extension you have.
But yeah i understand that soldering multiple times is bad, of course it's a bit too late it too tiny and i got it burned a bit...

Both i checked but i was referring to the cable coming from the kindle that i soldered

By the way, the adapter is usually ttyUSB0.

Sorry i forgot it doesn't disappear but it didn't say usb and if i plug the adapter nothing is shown, also after clearing dmesg nothing appears there. does it appear with just the apdater plugged in?

I know it's strange but it's from the kindle itself (hopefully i didn't ruin it with my bad soldering)

So i can check if it relevant or does have to have 1.8 written?

Can you elaborate i still fail to see what you mean, i also used a cable but something always has to be soldered at all times no?

U-Boot is supposed to copy itself from RAM to eMMC, and from eMMC to RAM, depending on which one has a missing copy.
But on some Kindle firmware versions, that doesn't work.
So avoid at all wiping /dev/mmcblk0. Keep your eyes open so you don't end up doing it by accident. You have been warned.

I don't actually need to wipe anything i just want it working again so i will only copy the new FW why wipe at all?
