I have tried almost all ACU7515 firmwares on s1fw.com, and I've found that this firmware work with my player! :shock: 8)
Just a little issue: this is a firmware for a 220x176 px display, while my display has a 160x128 px resolution! :evil:

Flashing the player with this firmware shows the hourglass in the upper-right portion of the display, then some "fluctuating pixel dust" because the CPU tries to display an higher resolution, and the display can't... but it works! :wink:

After the flash I have dumped the firmware from the player, and this is the s1fwx's result:

success.

I have read the BRECF285.BIN file, but I'm not an expert like you and I don't have understood which are the CEx commands...

Meanwhile, with the help of s1fwx, i have (unsuccessfully) tried to build a new firmware using the *.BIN files from this firmware and the FWIMAGE.FW file from your firmware, but the player loop on hourglass (translated: the firmware does not work...)

Lolita, can you take a look to it for me? :roll: ops:
