[QUOTE=KHFuture;4543575]I just did this last night. Yes, Winterbreak works. No, KUAL doesn't. There are scripts available where you can install the OTA blocker as well as an OTA checker to confirm OTAs are being blocked and that you are in jailbroken mode. Scripts such as Kindle Forge will have a GUI and allow you to download other scripts, such as KOreader,
Try running one of these two hotfixes again.
