Hacking the ZTE MF627
Its been a while since I’ve done a good hack article. so again I’m back onto my favourite topic of 3G modems. Thanks to the generous promotions at 3dongles4free I’ve been able to pickup a new Three dongle for next to nothing. As I’ve already got my E160G I didn’t really need this to be on the Three network. After a quick search around and a few suggestions from existing mailing lists I’ve found out that a hacked firmware exists and these cheap and cheerful dongles can be flashed to allow any SIM card to be used. This should be a simple job of updating the software and using the new SIM card.
First of all, grab the software pack from Rapidshare, due to the questionable nature of this copy of the firmware no one has been willing to host it on their own hosting, and I’ll keep to that idea. Extract the files from the RAR and you should have a firmware upgrade, and a installation folder for the connection software. As the existing Three connection software is very limited, the software package includes the Telstra version which allows you to define your own settings. Before you attempt the software upgrade, you need to remove any existing Three software, install the Telstra version and remove your SIM card from the dongle, then simply plug it in and run the firmware upgrade. This process will take around 15-25 minutes and once it’s done it’ll give you a prompt. During the upgrade do not power off your PC or remove the dongle from the USB socket. This will brick your dongle rendering it completely useless. Now, put in your non-Three SIM card and plug it back into your PC, the Telstra software should start-up and try detect the device, you need to configure the software for your provider’s APN settings, but the PDF document included with the software package will give you all the details you need. Remember, I take no responsibility for people bricking their equipment, you have been warned.
