If you will take the battery out, take the sim and micro sd out... then put the battery back in and hold both volume buttons while putting the usb cable in the phone it should get you into download mode... Go here and download the files... then follow the instructions to the "T"... It should get you back to stock.
It is recoverable from there... I have seen that screen a couple times. Search for RED TEXT in the original JF6 oneclick thread on XDA, and there are button combos to get download mode back up.
