Samsung SGH-Z300/ZM60

I got a Samsung ZM-60 from T-Mobile (incl. SIMlock). The first shock came after switching it on for the first time: Everything was in the T-Mobile magenta color. After some research, I found out, that it’s originally a SGH-Z300.

Firmware flashing

Instructions on how to flash a new firmware are on handy-faq.de. There also was a nice collection of firmware images on anvi.it, but seems to be down for now.

The best firmware seems to be the Z300AIEK1, since it is only slightly branded by TIM (an Italian provider?) and contains everything the original Samsung-Firmwares do.

You can use the supplied cable to flash the phone.

  1. run the Downloader Z300-Z500
  2. find your desired firmware file
  3. power off the phone, hold the 9 key and power it on so that the outer display shows “Download” on red background
  4. initiate the transfer

The flashing takes about 12 minutes and after that, you have the original Z300 Samsung theme.

SIMlock

To remove the SIMlock, there’s a manual at gsmhosting.com. You need the Qualcomm Unlocker and a PC with a COM1: port where you need to short the Pins #2 and #3. Then it’s a thing of 20 seconds to get rid of the SIMlock.

Downloading jar files

The phone accepts .jar files from any server if it sends the content type application/java-archive instead of application/octet-stream. This is easily accomplished by adding a .htaccess file with the line

AddType application/java-archive .jar

to the directory where the .jar files are on your server.

Phone identification

The phone sends the following User-Agent to websites:

SGH-Z300 SHP/VPP/R5 SMB3.1 SMM-MMS/1.2.0 profile/MIDP-2.0
