I solved my problem ,

i burned a linux image on SDCard and i formated the flash.

Then i can flash it normal again

Hello,??pacopad, would you please share your story a little bit more in detail?

This is a good reference of a new way for system recovery.

I think use "EraseFlash" can fix this problem

Here is the story. I flashed an Android image from a TV Box (i dont remember which one).

When the Android started , the board was detected as MSC device so i could do nothing with AndroidTool. When i tried to select "SWITCH" on Android tool or boot in Loader Mode , the board was n't recognized on my computer. Nothing in USB Logs.

So i burned a linux distro for rk3288 on a SD Card and i formatted the flash with gparted.

After that the board was recognized in Loader Mode with AndroidTool

Best regards

Hi Pacopad, how do you burn a Linux distro for rk3288 to a SD card?

Which Linux firmware file are you using?

Are you using the Rockchip SD Firmware tool, or just using the dd command?

We'd like hear more to complete the "Boot_Ubuntu_from_sd" wiki page. Thank you.

Hi BusyBee,

i googled and find this distro for rk3288 https://plus.google.com/+IanMORRISON. I burned it with dd on a sdcard and boot.

After that i was able to erase the flash with gparted.

Dont hesitate if you want more details
