Long story short here, I loan the tablet out for the weekend and on bootup it kept going to "Screen Calibrating" and would stay in a constant loop.  I figure the ROM is pooched so I attempt to reflash, this is where things went downhill quickly.

Previously rooted with RK 1.7 and (2gb fix) ROM installed - working fine

Then screen calibration loop - flash rom unsuccessful (Error- Flash unsuccessful IDB download)

Tried many different USB cables - no change

Read somewhere to erase the IDB, did so using RK Andriod too v1.29

Now im stuck, I have somehow entered RKAndroid MaskRom and nothing I do works.

Can it be saved from this point?   It does respond each time I plug in "Found RKAndroid MaskRom USB"
