I'm having some problems getting them on the Reader too, though they seem to work fine in the ConnSoft.
I know I'm flashing things correctly in general, because I've managed to add the clock and set the "Right" Jogstick movement to go to the next page (I left the "Left" one set to move backward in the History file, because I find that useful when I accidentally hit buttons, and backing up in the History is usually identical to going to the previous page

)
So can someone spot what I'm doing wrong? The error I get is when I go to flash the image (it builds it without errors), it tells me that the flash failed, and (something along the lines of) that I should reflash with a stock image. Perhaps that might help localize what's going on.
The only new thing I'm trying to do with this particular flash is add the fonts.
I've put them in the (SD Card Root):\files\opt\sony\ebook\FONT directory ... is this the right place?
I've attached the naming adjustments I made to the Calibri font, in case I've got something off there. If anyone spots an error, I'd appreciate knowing about it, 'cause I just ain't seein' it.
