[Lefinnois.net] @#$&*(&^%$#@... Because i can...

For me MTP protocol just sux ! A good MP3 player is in UMS mode or it's not a MP3 player. Sometime if the player is MTP mode only, it can be a good player... if you can switch it to UMS mode. Take Samsung YP-K3 for example... how can we make it better? Here is the stuff...

There is a special firmware for the YP-K3 :

• UMS mode USB Mass Storage, Yeah !
• tags id3 useless
• file browser
• Ogg support
• text reader
• Equaliser
• 2 news fonts
• 3 level of FM
• 3 colors for display
• No more sound limitation

It's à korean firmware coréen (version 4.06). Here is how to upgrade (Beware ! This is very dangerous. You can destroy your player. This have worked for me but... right ?) :

• download korean firmware 4.06 (the red one) :

• unzipping. We take : YPK3.IMG et YPK3.rom
• Mounting mtpfs/fuse (bwerk)

sudo -s
aptitude install mtpfs
mkdir /mnt/K3
mtpfs -d -f /mnt/K3   # debug/foreground

• copying firmware's files and unmounting

cp /tmp/YPK3.IMG /tmp/YPK3.rom /mnt/K3
sync
fusermount -u K3

• disconnecting K3. Power up. Error message "no DB". That's ok, no FS at this time.
• connecting K3

• Fine ! Creating partition with fdisk /dev/sda. type b (W95 FAT32)
• Making fs : mkfs.vfat -F 32 /dev/sda1
• mounting : mount /dev/sda1 /mnt/K3
• second copy of firmware's files
• unmounting and disconnecting
• Power up : firmware upgrade, poser up, image upgrade (interface)
• Power up : configuring language (korean default)
• Done !!!!
