New to the forum, hello ^.^
My secondhand Aura E2 arrived this afternoon, and I decided to jailbreak it like I did with my Kindle. Lo and behold, it's inexplicably harder. I managed to avoid the need for logging in and turning on the WIFI, but I haven't been able to install KOreader despite trying every recommended method listed on the github page save the KSM method (I don't think I could do it anyway). Despite being on Linux, I couldn't get the Linux script for the autoinstaller to work, and the manual method for both KFMon and NickelMenu did nothing when I tapped on KOreader.
I eventually figured it must be because my software version. So I tried to downgrade from 4.38.23038 to 3.19.5761. And got no reaction from my device. I really don't know what it is I'm doing wrong
