Coldbird and the guys on the PRO team have built a more stable platform for Prometheus and its PRO-C baby.
If you are using the Prometheus online client then you know there have been some bugs in the past due to how the online client was working with the firmware. Well now your CFW of choice has now been updated to work better with Prometheus, how? Originally there where some issues with the code one of which forced you to exit with the VSH menu. Also to note this version of the 6.XX PRO-C has be built to work with Prometheus and will be the basis for all future updates to the online client, so you shouldn’t have to update again for quite some time if at all.
