Hi Rockbox-Fans
I have already successfully installed rockbox on the same device some times ago.
However now it does not work anymore.
The steps I do for installation:
First mount the player as storage device with: jmtpfs ~/sonywalkman/
I download from dev_builds the rockbox firmware.
Then I unzip it to the root directory of the player:
unzip rockbox-sonynwze460.zip -d ~/sonywalkman/Storage\ Media/
Put the firmware as described to the same folder.
Unmount and unplug device.
Plug it again.
and then use the scscitool:
./scsitool_64-nwz-v27 ~/sonywalkman/ do_fw_upgrade
however here I get the message:
Cannot open device

Do you have any idea why this happens and how I could fix it?
Thanks in advance
Tobias

Hi, I think your missing the drive letter. Are you using linux to enter the cmdlines? Might have to enter the entire directory. The below is for windows os.

From https://www.rockbox.org/wiki/SonyNWLinuxPort.html :

"Type the following command, replacing X by the version number of scsitool and H by your drive letter:

     scsitool-nwz-vX.exe H: do_fw_upgrade  "
     
This for linux:

"Linux

Follow the Windows instruction but replace the drive letter (H:) by the path to the mass storage device (/dev/sdX), and run the tool as root or using sudo. You do not need the .bat file obviously, use whatever terminal emulator your linux distribution provides"

Hi Milardo,
sorry for not mentioning, I did it in two ways, once with relative path ~/sonywalkman and with absolute path /home/mypc-name/sonywalkman
However it did not work out in both cases.
I haven't executed it as root.
I will do this soon, maybe this helps.
Thanks!

philden:
I would try with the 'real' filesystem location in /dev (or similar), rather than your mount point.

tobiasj:
HI philden and Milardo,
executing with sudo did not change anything.
@philden: the device is not mounted in location /dev...
but on :
/run/user/1000/gvfs/mtp:host=Sony_WALKMAN_10FEA695760168/Storage Media
using gvfs mount.
Using this default mount point does not allow to copy files to the root directory of the mp3 player.
Therefore I use jmtpfs which allows me to easily mount mtp devices, as the Sony-mp3 player is.

Best Regards
Tobias
