Last week I opened my Zaurus SL-7500C and replaced the Flash chip with a K9F1G08UOM. (My original chip is also K9F... the only difference is the capacity).
I carefully checked the pins to make sure they are properly connected. Then I booted to the Service Menu using Fn+D+M. The up-right corner of Sevice Menu shows "SL-C760". But the chip wasn't properly recognized. Clicking on the version list gave me the following information: CPU: PXA255 A0 Board: c760 Serial No: 00000b0d ROM Checksum: bca1 RAM Size: 65536KB NAND modules(0MB) unknown[unknown] I tried all the NAND Flash related command (NAND restore and NAND Full Erase) in the service menu and they all gave me an "Error -2". Restoring NAND backup or installing U-Boot didn't work either. I can't put back my original chip because I damaged it when I removed it. (There must be some glue under the chip.) So basically my 7500 is dead. I heard that somebody has successfully upgraded their Flash chip. So maybe he can share his experience with me. I'd be very appreciated. |

No problem, I just wanted to set the record streigth.
If I'm not mistaken, Guylhem probably mentioned the older models, not pxa270-based C1000/3x00.... Thanks. -albertr |
