For first: My native Language is german so sorry for bad English.
I got a Sandisk Clip Jam and want to install Rockbox on it because the Original OS sucks. I chose Auto-Select at the Rockbox Utility and it detected Sansa Clip Zip (Stabil)
"[ERR] Original Firmware Unknown, please try another Version. Tested ClipZipV1 Versions are: 1.01.12, 1.0.15, 1.0.17, 1.0.18, 1.0.20, 1.0.21."
"Konnte F:/clppa.bin nicht laden."
Thanks, Kind Regards.
