Let's Unbrick your phone
Update
Use this method instead: Restores 3G and IMEI as well as unbricks any Fusion 2

Previous Method
Firstly, this is only a method for those who have a FULL BRICK, meaning your phone wont do anything aside from accessing the purple screen.
**If your phone bootloops or gets stuck at the AT&T logo and/or you can reach the Recovery menu, you are NOT at a full brick, this means you're soft bricked and you just need to do a full wipe and reflash your ROM.
As long as your phone can reach the purple screen by pressing and holding Power + Volume up + Volume down at the same time, we can fix your bricked phone.
If you do this, your 3G is lost forever, there will never be a fix. NEVER. You will still have 2G, and Wi-Fi speeds are unaffected.
People with a fully bricked phone will likely not care about that, but if you want to do this for kicks, you will lose your 3G, and no one can help. (This is why I've been sending this information via PM up to this point)
Okay, now that we've covered that:
I will begin with a quick run down; the Fusion 2 is strikingly similar to the Ascend Y201, so ROMs that work on that phone, work on this phone. The difference, however, is that they have an official firmware update(ICS) from Huawei, where the Fusion 2 does not. This of course is bad news for those of us who mess up our phones. Fortunately, we can use their official firmware to fix our broken phone.
If you decide to proceed, you should know, this will, initially, turn your phone into a Y201, so when you root, you will have to do so with the guides for the Y201, and not Shagerty's root guide. (I will provide the links you need below)
Once you have aquired root, and have CWM installed, you can easily flash any of the ROMs for the fusion 2 again, with no issue.

Please, be aware, this takes a long time, so you should be plugged in, or at least have a ton of battery. Also, don't freak out if you think its frozen, just let it do its thing. DO NOT REMOVE THE BATTERY! You will be left with a total paperweight.
