Got stuck with this on my Vega. Flashed it to r8 3 days ago, all fine until I changed today the USB mode to host.

Did the 2 second back button, 2 second power, let go of power button...etc Tried it about 40 times. Checked I had it right by checking load of other posts. Had power cable in. Just comes back to same screen.

Got a mac and can see it in the the System Profiler and tried reflashing...nothing

Booted into Windows partiiton, installed the USB driver...Windows see the device, tried running the restore, but all it sees is an unrecognised device

I have a brick that is useless. Someone please help before this thing get smashed up and into the bin

Pleas try this (to the letter!):
  • Unplug USB cable and power adapter
  • Reboot the PC
  • Turn off the Vega by holding the power button for about 10 seconds
  • Plug in the power adapter and connect the USB cable to both PC and Vega
  • Press and hold back button...
  • After exactly 1 second press and hold power button tto (don't release back button)
  • After another second release the power button (keep pressing the back button)
  • After yet another second, release the back button too...
It should be in flash mode now...

If not, try this:
  • Unplug the power adapter
  • Press and hold the back button
  • While pressing the back button, plug the power adapter back in...
Hope the device is in flash mode now...

If not, try again and again...

The big problem is those instructions don't work reliably. It took me 1/2 hour of trying to get my Vega (bricked by the r8 USB host mode kludge) into flash mode! :D

IMHO this kludge is end-of-life for v8 and v9 ROM, so needs replacing with a proper, ROM version independent, solution.

I have the dock now, so will be sticking with that for USB host until a non-bricking USB host solution is provided.

How did you do this? I downloaded the execute from the advent site, but it says it cannot find the device to flash? I assume because I cannot get it into recovery mode.

Can anyone confirm whether this issue is caused by us trying to switch USB modes while USB debugging is enabled?

I just temp-bricked my own Vega this way, followed the recommendation in this thread to reinstall Advent ROM then back to Paul's, and then first unchecked USB debugging before going straight to the USB mode switcher to see if I could replicate the issue.

But this time it worked!

Thanks.

After an hour of searching and trying, (bloody 2sec, 2sec, 2sec boot into recovery routine).

Finally got it to boot into recovery.

Thanks again.

Glad it worked out OK...
But actually Recovery is something different...
You probably mean flash mode...

Just an FYI, I got this same problem today.
I had installed BUZZs kernel and was trying to sort out the wifi issue as well as get the XBox 360 controller recognised when I got this error. (I had ADB mode enabled).

Have rectified it booting into the flash mode and restarting.

Previously had 1.08 and the older MCR on so am using this as an excuse to install a fresh the latest stuff. :D

This happened to me today too. Rebooted to Slave mode & my beloved vega said "no" well it actually said "Starting Fastboot USB download protocol" but it didn't, it just sat there in a sulk. I got scared, but remember all the stuff about the unbrickablity of the vega, googled the message, no1 result was this thread, followed instructions & reflashed. I'm now about to put Corvus v5 ROM on it to see how that flies.

Thanks you so much for imparting useful information like this.


I'm a happy bunny again.
