- added new feature which allows you to disable os full relaunch (only possible in combination with sysNAND, not redNAND) - added new option which allows to return to HBL after executing the patches and not launch to System Menu (only in combination with disabled OS full relaunch) - some clean ups NOTE to the new feature: The new feature to disable full OS reload behaves similar to the simple signature patcher except that it setups execution memory region from kernel for wupserver and iosuhax dev node code and starts those. So it's a fast simple signature patcher with the addition of wupserver and iosuhax dev node. Another addition to the simple sign patcher is that the patches reload themself when exiting settings. Launch image is disabled for this method though.
