Select CE5 ("o 2 28" in s1giveio), then try reading anything from memory address 8000 or above (e.g. "r 8000") while monitoring CE5. It should pulse low and then go high very very quickly, once the read is complete.

I've tried, but the pulse is too much quick to be seen with a digital multimeter, even reading more data (
"r 8000 200")...
I will try with an oscilloscope... if I find it
However, I've traced the CE line during the player's boot, and during the "pixel dust" it is fluctuating, so it seems that the CE5 line works correctly.

Maybe that one was mislabeled or GXBL177 is actually the backlight's part number, and GA177 is the actual display's part#. This confirms that your player has the "big PCF8833-compatible" type controller, probably LDS285,ST7669, or ST7732/35/73. Firmware for those are much easier to find.

I've searched in s1fw.com for ST7732 firmware, but the only that I can download (it seems that Italians providers have some problems with asian fonts in URLs...) does not work because is a 3.xx.xx version...

I've found that:
- Internal flash memory works
- Additional MicroSD flash memory works (no SDHC support)
- Keys works
- MP3 playing works (the display shows - distorted - folder, track name and volume icon)
I don't have tested the FM radio (but this is a minor problem). :roll:

I don't understand how merge two firmwares with this software, it seems to be used only for resource edit... and its use with the "half working" firmware for a simple edit (changing the default language) has damaged it (hourglass loop). :?
