ZTE MF627 Unlock Download

Saturday, November 13th, 2010

Important: Re-flashing of the ZTE MF627 USB Modem MUST be done on Windows XP ONLY. If you try it on another OS, you’ll brick it! (break it!)

This is the procedure I’ve now done many times.

1. Download this file from here. This contains replacement firmware, and will replace the software on the USB modem.
2. The file is a RAR archive (similar to a ZIP). So you’ll need an extraction tool to handle this file and extract the contents. e.g. winrar.
3. Extract the contents of the above file to a directory e.g. c:flash.
4. DO NOT USE A USB HUB FOR THE FLASH UPGRADE. (you’ve been warned!).MAKE SURE YOU’VE GOT PC ATTACHED TO A UPS OR USE A LAPTOP CONNECTED TO MAINS. (Enough credit in your electricity meter etc). THE FLASH UPDATE ON AVERAGE TAKES APPROXIMATELY 18-20 MINUTES TO COMPLETE, SOME COMPUTERS CAN TAKE UP TO 46 MINUTES. THIS IS A VERY LONG DANGEROUS TIME, IF IT FAILS IT WILL BRICK YOU USB MODEM. (aka stuff it!). It’s also probably a good idea to stop all other Windows XP application as well!
5. Install the software that comes with the USB modem dongle. After inserting the USB modem into your Windows XP computers’ USB port, Windows XP will do the plug N play thing, and install all the drivers, it will then Autorun the software installation and install the 3Connect GUI.
6. Unplug, and re-insert the usb modem, to check drivers are correctly loaded.
7. Select Start->Control Panel->System->Device Manager, Expand the modems section, you should see a ZTE modem.
8. Run FlashUpdate.exe in the c:\flash directory. (don’t worry that the update states is for the MF626, if you query the modem using Hayes AT commands, you’ll see this is a MF626, it’s just the MF627 is a black/green version OEMed for ‘3′)
9. The updater scans serial ports looking for the modem, when it finds the Diagnostic port, the Download Button un-greys. (you may need to maximize the application to see the Download box).
10. Wait for approximately 20 minutes. (see above) It will eventually announce when it’s completed and the Cost it took in minutes!
11. In the first few seconds, it disables autorun, and resets the modem, and waits 50 seconds before it re-appears again on the USB bus, so don’t be tempted to flash under VMware! So you should here it disconnect and re-connect to the PC (bing bong Windows XP sound!).
12. Your 3 ZTE MF627 USB Modem dongle is now been unlocked from 3 and you can put any network’s data SIM in it.
13. You’ll need to install different Connection Management software in the c:flash directory.
14. Once that’s been installed, create a new Profile for your Network Provider.

Not that this is a big issue, but I’ve noticed that using another SIM (other than 3), the light always stays in ROAM mode (solid/flashing red) rather than Green = GPRS, Blue = 3G/HSDPA.

The Telstra/3Connect connection manager software is able to correctly tell, whether you are connected at GPRS or 3G/HSDPA. You can still use your 3 SIM correctly with the 3 Connect software after flashing, but the 3Connect software will only work with a 3 SIM.

Luckily there are software programs that can over-ride this lock. I’ve used the following procedure to over-ride the lock in a 3 USB Modem (ZTE MF627) and replace the 3 SIM Card with an ASDA SIM Card. Your mileage may vary, and I will not be held responsible if this procedure fails, and turns your 3 USB Modem into a brick (breaks it!).

UPDATE (12 Dec 09) :- I originally thought that using a non-3 (three) SIM caused the ZTE MF627 to flash RED. This is not the case, RED Simply means GPRS mode!

For details on software please make a 10 GBP donation via PayPal and by return I’ll send you the software to unlock your MF627. The donation pays for the hosting of this website, and thousands of hits and free information I’ve provided on unlocking Three Mobile Modems.
