Stuck on Tequila Diagnostics on my Kindle 4th Gen

[ravenesss]

Sigh so I literally made an account here so I could get help.

I have an old Kindle 4th that I dusted off and reset before deciding to jailbreak it. The steps were going fine until I got stuck at the reboot option and I decided it wasn’t for me so I decided to uninstall the jailbreak, but now I’m stuck at this diagnostics menu.

My dilemma is that I’ve already deleted all the jailbreak files and I’ve already rebooted the device like 20 times via power button, even while connected to the usb. I’ve tried reinstalling the original updated software and it doesn’t seem to work either. The only advice is literally from 14 years ago and I don’t know if unjailbreaking has changed since then. What do I do? Please help me escape tequila hell and I will never attempt to be a cool hacker again.

For reference I followed the steps from NiLuJe Kindle 4 jailbreak.

Thanks in advance
