Infinity 2.0 now supports 6.60/6.61 with permanent CFW. However under such versions the Pause Game function will not work and device will crash. It's commonly say that you should disable the UNLOCK EXTRA MEMORY option in the RECOVERY MENU, but this option doesn't exist in Pro-C.
After some searching I found on reddit (couldn’t find the original thread) the suggestion on hibernation deletion. So here is how to set it:
- On the home screen press SELECT
- go to Recovery Menu – Configuration – Prevent Hibernation Deletion – change to Disabled
- Keep Pro-C but no Infinity (have to run Pro Update after each reboot)
- Downgrade to 6.20 with Chronoswitch Downgrader v7 (also used to remove Infinity using OFW)
