Hi everyone,

This is my first post and thread on this forum ( Yay ! ), so please be kind to me. I really needed help.

So I had just accumulated enough courage to jailbreak my Kindle 4 NT that my cousin gave me a while ago (after said cousin broke the e-ink but I got a spare off e-bay for cheap then replace the screen ). I did it using this link : https://wiki.mobileread.com/wiki/Kindle4NTHacking

Although that it worked perfectly, I decided to wipe it using kindle's reset menu since I don't want my cousin's book to be on there ( an action which I would then soon regret) after it is jailbroken. It all went south from there.

My newly repaired kindle is now stuck at loading screen.

It has a weird symptoms as follows

1. The computer would detect the kindle when it is connected via usb cable and mount ( This is on a Windows PC) while showing the stuck loading screen

2. I can also make it go to diagnostic mode by creating ENABLE_DIAG blank file on kindle drive from 1 or using magic down key and power button with MfgTool.

3. The usbnet thing worked and I was able to SSH into it, including flashing the image onto the kindle. But it had no effect ( no error on dd)

Here are the things that I had tried so far.

- 1. draining battery and charge it up again (to no avail)

- 2. tried using kubrick CD to restore it. Got nothing either

( It has finished its task, but after rebooting it still stuck at loading screen )

- 3. I also tried using MfgTool + down key power sequence to enter diagnostic mode then setup usbnet and SSHed into the kindle. I then flashed the mmcblk0p.img (ver 4.0.0) using dd then reboot to no avail. ( per information on https://www.mobileread.com/forums/sho...d.php?t=169645)

-4. I also remove everything in /var/local but still no effect.

Can anyone help me on this matter, I really don't want to buy a new kindle since I just spent money fixing the e-ink screen.

Thank you in advance
Mo
