I own an ARchos 7 HT Rev 1.

Its an older tablet I have not used in years because I was unimpressed with appslib.

A few nights ago while browsing I found an way to update this to use the android market.

I installed yar028.zip  from the arctable site.

I moved the image via usb to the root, this prompted me install and the install went well.

I then installed the market.apk and this installed well too.

My tablet was working well at this point, but I did not test it thoroughly.

Finally I noticed that in the Zip there is a folder called "system"  and it was different to the "system" folder on my archos.

So I deleted the system folder on archos and copied the system fold from yar028.zip via usb to archos.

Since then my system will not boot -- i realize it was a stupid thing to do but was wondering how i can fix it.

I am unable to mount the device via usb as the archos is perpetually in this loop where it tries to recover, format data and restart.

If i slide the power button to lock it will come up with a menu that gives a few options like factory reset 

(or something similar), update from sd card, update from udisk; however, I am unable to make a selection the device seems frozen at this point unless I just am not sure how to do it.

I would like to back track, install the image again and not act rashly and brick it again.

any advice would be appreciated.

Sorry if this is posted to wrong forum, please feel free to move if necessary.
