After some research...I found a pretty simple way of getting back to Stock Froyo.
a couple posts from the top of this there is a link to RSD 4.9...this is what I used.
I have a windows 64bit system. I did not load any motorola drivers this time, but I think I did long long ago so you may have to (see thread for those).
I Followed these steps:
To install the above files you need to follow these directions:
1) Switch your device to PC mode
2) Turn on debugging mode (settings>applications>development>debugging mode)
3) Launch RSDLite (make sure device appears in window)
4) Select SBF
you will end up sitting on the boot logo...don't freak out.
a) power cycle the device while holding the X key on the physical keyboard. (you should see an exclamation point triangle thingy).
b) press the search key on the physical keyboard. ( you will see the stock bootloader.
c) wipe data (factory reset).
You now should have a factory fresh device. Activation required, etc.
The reason I went back is tethering...I get too much value from tethering my other devices. GB is just not worth it to me.
