really odd 
try this “force update” … follow each Step Exactly
1. small flashdrive (2,4,8GB … no larger) formatted FAT32 … completely empty
2. re download firmware 3.12.13 again (if you already have downloaded it proceed to Step 3)
http://www.wdc.com/wdproducts/updates/?family=wdfwdtv_livehub
3. extract all 5 files onto the root of the flashdrive ie. No Folders
so you should only have these on the flashdrive
wdtvlivehub.bi2
wdtvlivehub.bin
wdtvlivehub.fff
wdtvlivehub.info
wdtvlivehub.ver
4. Open and edit (using Notepad) the file wdtvlivehub.ver
From this …
VERSION=‘3.12.13’
LOCATION=‘wdtvlivehub.bin’
PKG_LOCATION=‘wdtvlivehub.pkg’
ROOTFS2=‘wdtvlivehub.bi2’
To this …
VERSION=‘4.12.13’
LOCATION=‘wdtvlivehub.bin’
PKG_LOCATION=‘wdtvlivehub.pkg’
ROOTFS2=‘wdtvlivehub.bi2’
close … and save changes
5. Before inserting the flashdrive … check the detect New Firmware setting is “On”
Setup > System > Auto Detect New Firmware > On
6. Power off the WDTV (Press and hold Standby button for 5 seconds … switch off at the mains power)
7. “Safely Remove” the flashdrive from your PC and insert it into the front or rear usb input on the WDTV
8. Power On the WDTV
9. New Firmware should now be detected “New Firmware” notification will appear in the Home Menu. Press OK.
(it will say 4.12.13 … don’t worry, ignore it) … press OK to proceed)
10. wait until finished (it can take several minutes … it should not take longer than 10-15 min)
11. It’s also highly recommended after a Firmware Rollback (or upgrade) to do a *Factory Reset*
Setup > System > Device Reset > Reset All Settings Back to Factory Default
after doing the Factory Reset … check Setup > About again
If it doesent say 3.12.13 … then i’m at a loss
