Troubleshooting Kindle Unbrick not showing

Mtiton-66 · 11-10-2024, 01:25 PM

Good afternoon, everyone. I'm having some issues with unbricking my Kindle Basic 11. I've already tried basic procedures, such as checking and swapping the TX and RX cables. I'm using a USB-to-TTL FTDI232RL adapter modified to lower the voltage to 1.8V, but I'm only getting strange characters in the terminal. I’m unsure what else to try and would appreciate any guidance. If anyone has encountered this situation and could help, I'd be very grateful. I'm not sure if the motherboard is damaged or if there’s a way to reflash it.

Even if you did get it working you wouldn't be able to do anything unless it was jailbroken and setup for access over serial.

So, you’re telling me that if I had unlocked or jailbroken it, I’d be able to read the UART pins on my Kindle?
And is there no other way to rewrite its corrupted file?
