We have better things to do than downloaded and dumped an ROM to each request just for tell you if Field Test works...

You must understand that a ROM and an update is *completely different*.
Also, the ROMs are usually released after the updates are available.
So, you must wait.

Hello Developers,
I was trying to flash my Lumia 625 Device but I got some errors. But after sometime finally I got a trick. With this trick you can go from 2g to 3g without flashing your device. What you have to do is Just Dial *123# or 123 from your Lumia device. You will go instantly from 2g to 3g.
