This is a post to help everyone that has a Samsung Z serie mobile that is locked and/or freezed.

The explanation for how to do is already on this forum but to make it easier for everyone to find it, I'm making my 1 for all (Z series phones) post.

The supported phones for this process are (the Z series phones):

(as listed in the program)
SGH-Z140
SGH-Z140V
SGH-Z300
SGH-Z300M
SGH-Z500
SGH-Z500V
SGH-ZM60
SGH-ZV30
SGH-ZX10


To unlock and/or unfreeze these phones you must follow the next steps:

- Download and install QUALCOMM UNLOCKER (http://www.megaupload.com/?d=39RITNDZ)

- Install the propper USB drivers for your mobile (if it comes with CD, if that CD has the USB drivers, it's those ones that you should use, otherwise, download: http://org.downloadcenter.samsung.com/downloadfile/ContentsFile.aspx?CDSite=HQ&CttFileID=380589&CDCtt Type=SW&ModelType=N&ModelName=SGH-Z500&VPath=SW/200505/20050526174209031_USBDriver.exe).

- Have the proper USB cable for your mobile (if it comes with one, it's that one that you should use).

- After having your phone correctly connected to your computer (using the USB cable) and turned ON (with or without the SIM inserted), set the mobile modem COM port as one between port 2 to port 9 (ports 2 and 9 included). [Note]

- Connect (with something like a metallic wire for example) the 2nd and 3rd pins of the COM1 port (behind your computer), like the example below (imagine it like a COM - 9 pinned - port):
