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

You can use the supplied cable to flash the phone.
- run the Downloader Z300-Z500
- find your desired firmware file
- power off the phone, hold the 9 key and power it on so that the outer display shows "Download" on red background
- initiate the transfer
The flashing takes about 12 minutes and after that, you have the original Z300 Samsung theme.
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

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

AddType application/java-archive .jar
to the directory where the
.jar files are on your server.
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
