Hi, I'm sorry to say that it din't work - I heard that it was nearly impossible to brick a sony reader- now I agree. but for a moment I though I had it and I felt very special

!
Pepak, I really appreciate all the effort you had to help me - I was tempted by the result, but totally conscient that was a risky move. Thanks again!
Maybe I did some mistake but at first things occurred just like the first time I use boroda hack, so I decided to decribe how thing went to warn someone that wanted to use the same files:
1 - Unpacked the zip file Stoste - I got a Sony reader folder like the first time;
2- Connect the reader and put the folder in the root of the device (the "Reader" drive not the instaler); disconect the device
3 - The device starts running and apeared the inicial menu - I choose 6 to flash the image - and the process begin (exactly like I rememberer) -
4 - I got a message of error (something like "there was an error importing files". Here the problems begun:
5- I tried to connect the device - was no detected by the computer; so I rebooted and the flash menu apeared again: some process - same error, now I'm trapped in a loopping; connet the device again and it work: I decide to erase the sony reader folder then I was abble to format the internal memory, and have a fresh start.
6 - Just because I'm craisy ... I tried again: same error - some result - format internal memory - everything normal (deep breath ..)
Conclusions:
1- No cooler fonts: but now I appreciate more the ones I have

2- I learned a few thing about my reader, and lived strong emotions for an hour or so.
3 - The only bad result is that I started to dream about my new reader with pearl sreen (now with a device in perfect condition I can't justify it....
