How to reinstall original firmware in PRS-300?

I search a lot over the net to find a way to reinstall original copy of the PRS-300 firmware (I have a .img copy of it) and I found many post that ask the same, but everybody told how to install custom firmware (PRS+, eBook aplications etc.) and nobody tells how to install the original one. Please, I now there are a lot of firmwares running out there, but I want to have the original one, anybody knows how??

Thanks a lot!!

Have tried a hard reset on the Sony?

From the Wiki:

Hard Reset (PRS-300)

WARNING: A HARD RESET WILL ERASE ALL CONTENT ON THE READER.

1. Power off the Reader.

2. On the bottom edge of the Reader, using a pin or paper clip, press the RESET button.

3. Turn on the Reader.

4. While the screen displays Opening book... , simultaneously press and hold down the down arrow of the directional button and the 0 button until the Reset All screen is displayed.

NOTE: If Opening book... does not display on the screen, charge the Reader's battery for several hours before
attempting the reset process again.

5. Press the 5 button to reset the Reader.

Thanks for your response! Yes, I forgot to write it, I did a hard reset. It solved a problem with the firmware I have (PRS+), but it not bring the original one, only restore itself (the PRS+ firmware). Is there any way to flash the original firmware?

Flashing is above my pay grade. Hopefully someone will come along soon with an answer.
