The Linino image corrupted on Yun while "U-booting".

Official Hardware Classic Yún
1

Dear Sirs!
I got my Yun dead while reflashing the Linino image with U-boot. Please, don't ask why I did that...I mean "U-booting" - it seemed that was my mistake.
Now the usb-led is always on and it is possible to upload the YunSerialTerminal example but there is nothing can be seen in IDE Serial Terminal.
Holding the wifi reset button for more than 30 seconds gives nothing. So I believe that the image is corrupted...
I do realize that warranty is void but is there a way to overcome the issue I described above?
Your prompt reply will be highly appreciated.
Best regards.

[ 41.460000] fuse init (API version 7.20).

This is in the final steps of the boot process, if you are getting this far you missed failsafe mode.

You have to be VERY quick to interrupt the boot process, I do it this way:

  1. Upload YunSerialTerminal
  2. Open Serial Monitor
  3. Put an "f" in the box at the top of the Serial Monitor
  4. Push YunRST button by the leds
  5. Have the cursor over the "Send" button at the upper right of the Serial Monitor
  6. Click "Send" when "Press the [f] key and hit [enter] to enter failsafe mode" comes up

You should see this:

[    5.290000] Error: Driver 'gpio-keys-polled' is already registered, aborting...

[    5.330000] scsi 0:0:0:0: Direct-Access     Multi    Flash Reader     1.00 PQ: 0 ANSI: 0

    Press the [f] key and hit [enter] to enter failsafe mode

root@(none):/#



Notice the boot counter has only gotten to [ 5.330000] when failsafe is available, the fuse init is at [ 41.460000]

Make sure you are in failsafe with the `root@(none):/# `prompt, if you see

Hit any key to stop autoboot:  4  3  0

you are uboot, just press the YunRST again and wait for failsafe

Thanks for all, but it isn't possible to do. After pressing Yun Rst boot process don't initiates. I think boot flash is corrupted or erased.
How can I reload boot system if I haven't life on this side?
