USB-charging the Nexus 4 on Windows 7

There is a bug on Windows 7 that prevents the Nexus 4 to charge when it's connected to a USB port. The problem seems to be related to the latest Nexus 4 update in combination with the Windows USB driver. Luckily there is a workaround to this problem: simply disable MTP mounting on the Nexus 4:

• Go to Settings > Storage > Menu > USB Computer Connection  
• Unclick Media Device (MTP) 

The Nexus 4 should now charge when plugged into a Windows 7 computer.

Enable MTP support on Elementary OS

I'm currently running Elemantary OS on a Medion E1210 (Akoya) netbook as ubuntu became too heavy. The netbook has been upgraded with a 128GB SSD from Kingston and is operating very smooth considering the limited cpu. One small problem remains: my Nexus 4 only mounts as a "Media Transfer Protocol' device (MTP) instead of the classical USB Mass Storage device. 

Luckily, it's very easy to add MTP support to Elementary OS by executing the following commands in a shell :

sudo add-apt-repository ppa:langdalepl/gvfs-mtp 
sudo apt-get update 
sudo apt-get upgrade 

After reboot, the nexus 4 was mounted properly.

Switch the YP-S5 from MTP to UMS

I managed to switch the YP-S5 from MTP to UMS by installing the Korean firmware v1.50. I don't understand why North America and Europe are stuck with the MTP version while Asia and south America get the UMS version. Perhaps Samsung wants to experiment with DRM on a limited scale?

MTP (Media Transport Protocol specific for Windows Mediaplayer) is really not user-friendly:

• Doesn't work under macos or linux (support through libmtp is still limited). Ubuntu is my main OS .
• I couldn't get it work under XP ("error mtp device")
• Does work under Vista, but only after installing the latest patches.

Use at your own risk -- not sure if this voids your warrranty. But the YP-S5 did survive my unsuccesful attempts with the previous firmware v1.07.

Download the asiatic V1.50 version from Samsung Singapore (it's an English site):

http://www.samsung.com/sg/support/download...disp_nm=YP-S5QW

Unzip the file and under Vista, put the S5.rom and Config.dat in the root of the S5. I also put he Config.dat file in the subdirectory SYSTEM/ -- not sure if this is needed, but it doesn't harm... I had some trouble with copy/pasting the files. Drag and drop did however work under Vista.

After unconnecting and starting up the YP-S5, the new firmware is installed. The display shows up in Korean. This is quickly fixed in the Settings/Language menu. The first submenu item allows you to switch the language.

The S5 is now automatically supported under Ubuntu, but with a small issue: two S5 devices are mounted. No big deal...

UPDATE: Maybe it's not necessary to start from the Asiatic version; the 'original' V1.50 MTP version can also be switched by altering the Config.dat - this info seems unverified, however: http://mp3.generationmp3.com/2008/05...le-samsung-s5/

UPDATE 29/6/2008: apparently, you need a USB 2.0 connection to your YP-S5. See the comment below
