Since I didn't block the auto-update (my big mistake), my jail-broken kindle paper white 2 updated the firmware to 5.6.1. The Jail-break tools I used is 1.12 not the latest one (1.14)
Now, I can't use the KOReader and any other awesome tools here any more.
Tried to put the latest jailbreak (1.14) to the root directory ( /mnt/us ) as what I previously did, but the update menu is grayed which is samed as described by @NiLuJe in this thread.
I can still launch the KUAL in 5.6.1, so I copied the MR Package Installer to KUAL extension folder. Question is which menu should be clicked (see the attached picture)? Actually, I clicked both of them and got the same result - flash back the main screen.
I am wandering, in my case (before update to 5.6.1, didn't update the jailbreak to 1.14.N), there is no way, at least for now, to jail break and bring the KOReader back again, is it right?
Thanks for any comment.
