IOS 6.1.3 Firmware Fake Gone Wrong! (Jailbreak)?

I installed "Firmware 6.1.3 Fake" from iHackStore, while on iOS 6.0, then whenever I tried installing something, it would attempt to remove Evasion 6.0-6.1.2 Untether, getting scared, I immediately removed the Firmware Fake, thinking it'd solve it. WRONG. My iPhone stayed at 6.1.3 yet I'm still jailbroken. Now whenever I try to install something, it attempts to remove the untether, and aborts whatever I try to install or remove. Any suggestions would be greatly appreciated.

You can fix this problem by manually re-changing the iOS firmware,

If you don't have iFile, you can download a. Deb file from the internet and manually install it.

Ps, don't forget to save the changes and do a full reboot after you edit the iOS firmware.
