..and if that doesn't work you might also like to use the "R" button on RK27DM.exe (
Roc
kchip
Device
Manager) program just to get your player into rockUSB mode - (monitor this in remove hardware icon manager)

Then you can use the Upgrade tool to install the firmware folders (no rkusb.tag needed)
download upgrade tool here:-
http://www.mympxplayer.org/rockchip-...v25-df881.html
Player needs to be in RockUsb mode to use this, remember to check this in remove hardware icon manager)
So
1) If your player is dead and your firmware partition is damaged then connect it to usb.
2) Run RK27DM.exe and load in
any RKW firmware.
3) If the R button is active just press it, (if no R button is active then install the rockusb27.sys driver)
4) Click YES on the 2 message boxes that come up and watch for the RockUsb icon (in remove hardware)
5) when you get the icon close the RK27DM.exe program (still with the RockUSB icon active)
6) Run the upgrade tool you just downloaded.
7) Load firmware folders into upgrade tool.
8 ) Press the upgrade button and watch it do it's thing
9) When finished you just need to format the main 8GB memory in Fat 32
I used this method to recover my player when i corrupted the firmware by shutting the pc down with the player connected..

ops: It worked a treat for me,
but remember it doesn't work if your firmware partition is good. but you can use teclast.sys or rkusb.tag on a good partition instead..
