Android tablets and sbf

I recently had to reflash my droid using rsd lite. I was wondering is it possible to do the same thing with a coby kyros?

Rsd lite is for motorola devices only. You'd have to manually flash any images you want to put on the device.

 

Wouldn't that be the same thing as reinstalling update.zip from the Coby site?
For MID7015:
COBY - Kyros™ Internet Touchscreen Tablet
has the update.zip and video showing how

 

You'd have to unpack it and remove the date assert from the update script..

 

Tell me more about date assert.
This week I plan to experiment with update.zip to unzip - zip - sign (found a java script). I know that newer MID7015s come with a newer build version and refuse the update.zip - apparently due to the date stamp. Would I hit a trap of not being able to go back to the update.zip due to date assert? That is a newly signed update.zip would have a later date than the original thus not letting me re-install the original.

 

was there another update?

 

System Info - from "About device" in settings:
Model number: MID7015
Firmware version: 2.1-update1
Kernel version: 2.6.29 Root android 2.1
Build number: MID7015 1.6a_20101105-2
after update the same except:
Build number: MID7015 1.6a_20101124-3

Newer units ship with a build that is newer than 2010 11 24
I think the - number is back to -1 though.

I checked the Coby web-site today. Always the same size file as what I downloaded in December. I don't think there is a second update.zip.
