1)Download Rockchip Batch Tools v1.5. Download firmware as needed.
links : http://www.mediafire.com/download.php?koja23446mrl6zb or http://www.arctablet.com/blog/archos-tablet/flashing-your-rockchip-3066-based-tablet-rockchip-batch-tool-1-5/
2) Open your UG802 (gently) with a plastic opening tool (used for mobile repair) or guitar pick. (do not to break clips)
3) Locate your NAND chip and the 2 pads next to it
4)Short the pads while plugging the UG802 into your computer. Windows >>> detect a new device.
5) Under control panel –> device manager, right click on unknown device, and choose update driver. Install the windows drivers located in the Rockchip Batch Tool folder. Should see “RK30sdk” device.
6)In Rockchip Batch Tool v1.5 . Select firmware image “xxxxxx.img” and choose “Restore”.
7)If successful “Restore Done Success<1> Fail<0>“. You are done
IMPORTANT: The method may break/destroy your UG802’s device. I am not responsible if you hurt yourself or your device.

This is old post:
Since firmware update Finless ROM 1.7 WiFi issues is fixed.
A simple way to fix WiFi issues with UG802 (remove antenna outside the case)
1. Open your UG802 with a plastic opening tool or guitar pick. Be careful not to break your clips.
2. Using sharp knife make/cut a hole on the case. Make sure WiFi wire is not pinched.
3. Remote WiFi antenna outside the case, or way from USB port.

got my self a new toy.. UG802 could be considered as large USB stick with HDMI connector that connects directly to your TV. So what? for $50-60 you get dual core computer. My goal make a home automation central station out of it, that will connect to Blue Iris CCTV server, weather station, and home automation. Very important: Use quality USB Power Charger > 2.1A
Rockchip 3066 Android 4.1 1.2GHz Cortex-A9,beyond MK802 mini PC. (can run as 1.6GHz need large power supply)
Quad Core GPU
1GB RAM 4G ROM
With 3D Graphical processor
Use 1GB DDR3 4GB ROM high capacity memory.
With WIFI 802.1b/g/n Wireless to get rid of the wire bond

How to fix:
A lot of these have burned board, so just open it and plug your hard drive to other external SATA USB connector.

My Lenovo Y560 laptop started to over heat few days back. Here is simple fix (clean CPU fan).
Cleaning had lowered my CPU temperature quite a bit.
If this does not work for you, option 2 (from google search)
BIOS 71 > Some users reported heat problems after upgrading to the new BIOS version 71, since it seems that the fan speed is bugged in this version and downgrading to an older version should help.
A nice software to monitor Y560 temperature Link
Windows XP mode could not be restored because of either host processor mismatch or lack of hardware assisted virtualization support in the system

The reason is that by default when you close Windows XP Mode, Windows Virtual PC will put Windows XP Mode in hibernation. If you dont know what XP mode is, its great tool for Windows 7 users that want to use old hardware or software. In my case I was using it to watch TV over old USB tuner card.
Anyway, fix for this is very simple
go to: Location “C:\Users\[user id]\AppData\Local\Microsoft\Windows Virtual PC\Virtual Machines”
changing the name of the .vsv file, and that will force it to start booting the VM fresh when you start the VM again.
To prevent this error from happening again in the future, you can change the virtual pc option from Hibernation to Shutdown.
1. Open Virtual PC.
2. Click on Tools and then click on Settings.
3. Under the Close tab, change the option from Hibernate to shutdown.
4. Restart your computer and start your Virtual PC for the changes to take effect.
