Thanks a lot for this jailbreak!
I have installed it on my Kindle PaperWhite 4 (2018) WiFi, 8GB (G000PP) and it works great. Finally, I can customize the device so that the PDFs are easier to read.
Regarding USBNetwork:
I have installed it and I can successfully activate UN and reach the device. However, it always prompts for an SSH password. Regardless whether the WiFi is on or off (by default I always turn it off). The telnet port is closed. Any ideas how could I login into the device?
I wanted to adjust the configuration, such that I can use public keys for authentication, but I can't get it to compile, because I am lacking a lot of PW2 binaries (not included in the package sources or the official repo).
Thanks in advance!
