Kindle Oasis 8th G0B0GD09 freezes and gets stuck on the big tree interface, USB cannot be recognized, can it be repaired by disassembling the TTL?
Hi, everyone
Kindle Oasis 8th G0B0GD09 freezes and gets stuck in the big tree interface, USB cannot be recognized, can disassembling the TTL fix it?
I used TTL to read the boot log as follows:

The problem is solved. I found a professional technician on the Xianyu app in China. He fixed it for me for only $6.88. He should have re-flashed the kernel and system through TTL, and now it is completely back to normal.
It seems that as long as TTL can enter the boot mode normally, it can still be fixed, but it requires professional technology.
