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](http://www.handy-faq.de/forum/showthread.php?t=13916).
|
||
|
|
There also was a nice collection of firmware images on [anvi.it](http://www.anvi.it/forum/index.php?showtopic=20637),
|
||
|
|
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*
|
||
|
|
1. find your desired firmware file
|
||
|
|
1. power off the phone, hold the <kbd>9</kbd> key and power it on so that the outer display shows "Download" on red
|
||
|
|
background
|
||
|
|
1. 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](http://forum.gsmhosting.com/vbb/showthread.php?t=239111).
|
||
|
|
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
