    I flashed the Infamous rom and I lost 4g. I wiped data, cache and dalvik before install so what did I do wrong?

    Check your APN settings. You may need to add it back.

    Its says H+ in the status bar where the 4g icon would go. I flashed back to my back up and had 4g again so I'll flash Infamous again and see if something changes.

    Are you in an area that has LTE? It looks like your getting 4G, HSPA+.

    No. At my house I get regular 4g and when im in town I get 4g LTE. But on Infamous it says 3g at my house when normally I get just 4g. It seems like my 4g is turned off when I'm on Infamous

    Try speedtest.net. See if you're getting the normal speed you would on 4G.

    APN for T-Mobile LTE: fast.t-mobile.com

    Also check in mobile settings to make sure LTE/GSM/WCDMA is enabled.

    Yeah the APN and mobile settings are correct but where I usually would get 4g it would say 3g and sometimes H+ would pop in. And not once I got 4g lte even in town where I've had it before. I tried adding the APN and still nothing. Tried reflashing the rom and even let it sit for more than 10 minutes.

    Well I figured out a possible reason why my 4g wasnt workibg right. It was probably cause I had infamous 3.3 installed. I downloaded 3.6 and 4g was working and everything was smooth so I finally have the rom I want on my phone. Thanks everyone for helping :)

    Did you do a clean install? Check your APN settings?

    Are you running a aosp rom? The touchwiz roms runs fine with 4g and everything but i like more the aosp roms.. any help?

    No, I'm using touchwiz. Maybe try reflashing the rom. Have you checked the thread for the rom to see if anyone else has the problem?

    You might also try a different kernel.

    It's infamous's alphaS4 7.2 Rom with bioshock Kernel.
    read the changelog, read the steps.
    I myself, android forums, XDA, or anyone else are NOT responsible if your phone goes kaput.
