KT4 serial port unbrick?

[Axlm_7_0]

Hello,

I accidentally bricked my Kindle Basic 10th generation by trying to fake register it using this guide, I was wondering if there is any possibility of recovering it via serial port.

It was jailbroken and it entered bootloop after I failed fake registering it. I had USBNetwork installed so I tried to set it to run on boot to try and remove the file from my Kindle, but it now refuses any connection and I've locked myself out of its internal memory by configuring USBNetwork to run on boot since I figured out too late that I can't change the configuration from internal memory if USBNetwork is running.

So my last option was to try and restore it via serial port, I have already opened it and located the serial port. The only thing remaining is buying a serial adapter. I was thinking of buying this one, but I wanted to make sure that I would be able to at least try doing anything before doing so. This is the adapter that I was thinking of buying https://www.amazon.com/DSD-TECH-SH-U.../dp/B08BQZSKT2.

Thanks in advance for any help .
