Hi, I stupidly enough mounted /dev/mtdblock0.

The sound begin to stutter and finally I got a red display.

Device could not be turned off..

I powered it off by pressing the power button for 30 Seconds.

Now it wont boot, not even a flicker on the display.

Is it anything that can be done?

BR.

Yes, it still can be fixed.
First check if your rexcore has a recovery mode installed.

Press the two outside buttons on top of the device, keep them pressed and insert the power cable.
Let it boot up and see what it tells or if it also hangs.

If that does not work there are other options.

I fixed it finally , but it was quite a job, mostly because of a lot if information missing,
If anybody here new, I guess they dont feel like sharing.

I had to port the the usbboot1.4 from windows to linux (not so hard)
tweak the u-boot-1.1.6 to the specific nand flash of my box (hard), specially the
mixed mode of BCH error correction used.
guessing the partion layout of the nand.  (not so hard).
As somebody here thought, the J4 header on the board is the
uart, pin 1 rx, pin 2 tx, pin 3 +3.3V pin 4 gnd.

Anyhow I think it is a very cool, hackable device with it its ingenic 4755.

Maybe we should start a real hackers forum for this device?

Fine with me. I can make a new section for this.
What name/purpose for the section? "Hardware tweaks and mods"  ?
Just name it and I will make it.
