Service [Q] SGH T999 and Roms.

I had recently obtained a s3 its a T-mobile, its running 4.1.2, with the T999UVDMD5 baseband. I rooted it, flashed xposed(haha the only thing XD). Well, reading about/friends have said there was trouble with the 4.3 update so I decided to stay on 4.1.2.

However, now I've decided to flash a custom rom, and I have noticed the different labels(D2lte, D2tmo, D2usa) and I had read from http://forum.xda-developers.com/show....php?t=1736477 "As of right now, the roms for your S3 are not meant to be used on other S3 variants" .

I have a few questions:
1.There was a baseband update, should I update it? If so, how exactly?
2.Would it be wise to flash a D2lte on This T-mobile device? I was looking at Resurrectionhttp://forum.xda-developers.com/show....php?t=2692481(originally waiting on cm11 but.. Yeah lol)
3.Looking at KitKat rooms, which ones could I flash?
4.Would it be safe, if I did flash a 4.4.2 to restore a nandroid backup of my fresh rooted stock 4.1.2.
5.Lastly, what kernel would you say use?(Sorry to ask, curiosity as to which i could flash)

I appreciate taking your time to answer my questions and have a good day!

1) custom recovery.. There are zips available to flash
2) d2lte covers all d2 devices so its safe
3)Any on the development threads
4) Yes
5) like on 3, you can flash any kernel in the development threads, experiment and see which one works the best for you!

To answer your questions:

1. You do not need to update your firmware - I'm still on MD5. Modems, however, can be flashed separately from firmware.
2. You can flash d2lte ROMs on this phone as it's all one unified build for US SGS3 variants. (I.e. T-Mobile/AT&T/Sprint/Verizon SGS3 is now all built under d2lte).
3. As far as which KK ROM to flash...just try them all out and see which ones you like the best. Each ROM has different features - see which one is right for you.
4. If you don't update your firmware, then yes. (FYI, flashing a custom KK ROM does not update your firmware. However, if you flash one of the 4.3 root66 files that has firmware included, then it will update your firmware).
5. Again, try it out. It's hard to say which ROM/kernel combination will work best. I suggest you read the forums to see what people think of them.

Hope that helps.

No problem, and i forgot to say but the only time you might need to update modem is if you flash a 4.3 touchwiz ROM, other than that its not really needed unless you want to experiment and see if one gives you better results

Oh, and one more thing: DO NOT flash a ROM that is for the international version of the SGS3 (i9300). It will, most definitely, brick your phone.

Don't know if you knew that or not...just wanted to make sure.
