lol what I did to get my rockchip fixed (omega V89) was i ran the tweasers across the legs and it clicked a few times and i missed em all and then didnt click at all so i turned it on while it was still pluged in to the pc (the main swich) and then it went into update mode then it updated and it worked but it said data was full so i pluged it in and then it told me to reformat and now everything works ok on it. hope my story helped anyone!

HI! Recently I bought an mp4 player from a reseller from Greece, named Plaisio, Turbo-X tp2 player. I've found that is exactly like
Teclast C260

A simple image is here:


My problem is that I've tried to upgrade the firmware and I upgraded with a different version and now my player is DEAD. Only a white(light gray) screen is seen. For 3 times I reinstalled the firmware but I didn't found the good one. Help me please finding the good firmare and a way to upgrade, because after those tries I cannot anymore get the player in the Upgrade mode. I read almost posts here but I didn't find some useful information to solve my problem.
I want to reinstall my old firmware or a new version, doesn't matter, I want to see my player working.
Thanks a lot!

You need to be in RockUSB mode first.
Double click on the remove hardware icon in your system tray.



If you are in RockUSB mode you will see the icon in the window like this:-



You MUST be in RockUSB mode to change your firmware.

To get into RockUSb mode
1) switch the player off.
2) hold down the menu key.
3)connect the USB cable
4) wait a few seconds
5) release the menu key
6) look for the RockUSB icon.

7) If you see the RockUSB icon, load the CORRECT firmware for your player using Consumerupdate program.

It this fails then as a last resort I suggest you do the Hard Reset already described to get into RockUSB mode and load the CORRECT firmware for your player using Consumerupdate program.

You will need to open your player to do the HARD reset, but only try this if you are confident with opening your player or you might break something!

You may find it easier on your player to try shorting the following 2 pins:-


These are the actual pins (posted on a Chinese website) which have also been found to need shorting to get into RockUSB mode, use tweezers or a small jeweller's screwdriver..





This would force the player into RockUSB mode upgrade mode, but you MUST look for the RockUSB icon

Finally I brought my player in rockusb mode and I upgraded my firmware but it's still not working. I've tried 3 versions of firmware for Teclast C260 and blank screen is still present (I think this is only the backlight without any useful information ==> not working). Even more, now the flash is not seen as a storage device (like a partition).
Is the any chance to save my player or it's not?
I still can upgrade software with HW reset but I don't know if it's ok to do that so many times... after some experiments it may be unrecognizable by the computer, meaning flash is burnt.
Any idea?
Maybe where I could get the good firmware for it?

Now you know how to get the player into RockUsb mode you still have a good chance to get your player back.

Have you tried this firmware from the omega v88?

This is a Teclast c260 copy like your player.

Don't worry about killing the memory, you can't use it anyway, right?.
You just need to try only firmwares from players that look like yours and that have touch controls.

If you have to open the player get the pcb number and the number from the display there may be a firmware you can use on http://www.s1fw.com/ your player uses only firmwares for rockchip RK2608A with touch controls.

BTW, if your plaeyer has screws on the sides than it is not a teclast player at all and will not work with teclast firmwares, try what knob has suggested with the v88 firmware as this also has screws on the side and is a copy of the teclast design
