ADMIN please make this a sticky
The procedure to change firmware....
The following assumes you already have the GREFWTOOL tool with the firmware 3.8 in that folder, and ezscan software ( FREE from whistler) on your computer and you have archived your data.
1) Start the GREFWTOOL tool
2) Take the batteries out of your scanner and unplug it
3) Press and hold the menu button while inserting the usb cable (one end already plugged into the computer) once plugged in, let go of the menu button. WAIT for the beep from your computer. It could take up to 30 seconds.
4) In the grefwtool go to settings and press rescan, the comport should be filled in, Scanner type is the scanner you are connected to, Firmware is what you want the scanner to become WS1080 in most cases unless your restoring..
5) Select connect to scanner icon
6) Select UPDATE firmware in scanner icon, select firmware ws1080e U3.8.bin (DO NOT select the download firmware button! it will give you the latest and it only partially works. It will not provide DMR, DIGITAL or P25 on your scanner as of this writing) Your scanners should now be upgrading the firmware. It will shut down when done.
7) Go into ezscan (NOT iSCAN) do the DSP UPDATE, library updates and/or restore from archive or. transfer database if needed. via the cable or card reader DO NOT ALLOW A FIRMWARE UPDATE UNTIL FURTHER NOTICE AND TESTING SHOWS ANOTHER FIRMWARE WORKS 100%
8) Turn your scanner on, if it loads fine and works, put the batteries in and enjoy the fruit of Eric's work!!!
