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!!
