K4 Debrick K4, mfgtool fails

manqka05 · 09-18-2021, 04:37 AM

Hello guys, help if you can.

I have Kindle 4 with software version 4.1.3.
Tried to jailbreak it by uploading the required files from kindle-k4-jailbreak-1.8.N.zip
After rebooting I couldnt see the Jailbreak success screen and I got stuck into System diagnostics and it wouldnt boot to home.
By mistake I clicked on "Install Fastboot Bundle".

I downloaded MfgTool.exe - it mentioned deleting the current profiles and putting the ones from Kindle_bootmode.zip - FAIL - I could not find this zip anywhere.

When running the MfgTool it says "No usb ports selected". When going in options -> configurations -> ports it crashes.

I am running on Windows 10 laptop with USB3.0 ports

Can you help me with further ideas?

In addition, the screen is turned ON. Device is no longer visible when connected to PC.
Buttons do not move the selection on the screen, so its frozzen good.

It is completely frozen. The screen is ON but the buttons do nothing.
Cannot even turn it off.
PC no longer recognizes it as a connected device.
