PRS-600 Bricked device

[superbet]

I need your help.

What happened was:

I installed PRS+following the instructions. 1st I installed base, then I copied the PRSPInstaller folder to root and restart the device.

Everything was fine, then I reconnected the reader to my PC and deleted PRSPInstaller folder, as told in the instructions.

2) Install the update
2.1) Unpack PRSPInstaller folder from this archive to the root of the internal memory of the reader.
2.2) Restart the reader (there is no installer UI), installer will do all necessary steps during startap (invisible to the user, takes a couple of seconds).
2.3) Delete PRSPInstaller folder from internal memory (if it is still there )

I disconnected the reader and.... A screen without icons, just the grid appears and a leyend in the status bar that reads: "1 fskin:/l/string..."

The reader is no longer recognized by mi PC. I can't reboot it, reinstall firmware, nothing...

What can I do???

Fixed. Uuuuuf!!!

I press reset reset reset reset until the yellow light blinked, then I switch the power button and when the reader responded, I connected the usb cable.

I formated the reader and then installed base again. It worked.
