Anyone with a Coby Kyros MID7005?

I stupidly rooted my Kyros, messed with the system, and by all means messed it up. I'm a total n00b, I know. I need to get a stock ROM - and I would appreciate if someone could help me push through the signed Google Apps, without Recovery Mode, because the update "always fails." I can give you the exact error, if I retried but I don't know it right off the bat.

I'm missing at least two of the stock functions, one of which I purposely deleted, but I guess I'd rather have it back, and one which just mysteriously disappeared. Is terminal also a way to modify what is on the tablet when one does a factory reset? I would be much more interested in setting up additional apks.

Missing:
Contacts & Dialer Package
Gallery (I seriously don't know what happened to it...)

 

if you d/l the update.zip from coby's website and unzip it, you'll find all of the stock apk's in system/app/ after unzipping it. you can then use adb to push them onto your kyros.
