I'm going to guess you are either running a 64bit windows version, or the driver wasn't installed, or your model has otg disabled. I don't have some variations of these devices so I only really can say what others tell me works or doesn't work. There was a discussion of iuw awhile back in this thread that may help. If you cant otg on your tablet, then youll need a bootable sd to flash it. HOWEVER when I try to flash recovery via sd on the other tablet I have (7lp if I remember correctly) it prevents the system from booting properly.
ok lol i tried burning it on another pc didnt work im going to try to boot it on a vm 32 bit system see if that helps any....any way i can tell if otg is disabelled? and i wanted to go the bootable sdcard way but must be a ius file is there anyway that it would be able to flash the recovery using a bootable sdcard? thanks again
