if you get a ....X.. installing rxTools 2.6 you will not be able to use AGBWhat ? Really ?!
*tests* O.O
wow... thanks for the info
to fix it, try to delete the rxTools folder from your SD Card, then go back to 2.5.2, install a patched AGB_FIRM, then go back to 2.6 and all must be fixed
good luck testing
