Help Kies fireware upgrade encountered!!

[Branden1366]

Okay so i installed a Clockworkmod recovery (that was hard enough because USB drivers were not working very well and yes I've got kies and i install the right Samsung USB drivers) and then installed the Cyanogen (CYANOGEN+OS+12.1S+V.1.0+s2+GT-I9100)
after i installed it, it was working fine but i was going to go on Clockworkmod recovery adn back the phone up but Cyanogen installed a Root thing there so there was no clockworkmod so i try to do something on it i cant remember what but then it came up with that stupid warning sign saying (firmware upgrade encountered an issue. Please select recovery mode in kies & try again.) but my S2 Gt-I9100 wont connect to it. (says its unsupported) !!!
-Thanks

Reflash Cwm or Twrp and reflash the ROM and Gapps. Or boot into download mode and flash stock firmware from Sammobile with Odin. If you're going to flash stock firmware you can flash it from the firmware upgrade encountered an issue screen or download mode.
