[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] faslane:
The U firmware isn't a ROM it's actual firmware you flash in Odin like any other official firmware so doing so your phone will be rest, unrooted and will boot up as if you just unwrapped it. The version if Odin is tweaked for this firmware so only use the I e in the zip. Don't download some other version...

The U firmware contains zero bloat and why it's so fast because NO carriers have touched it. There's a couple apps preloaded you can disable and I think 2 Samsung apps and that's it so it's VERY fast. I'm on the same T-Mobile S7 Edge and since T-Mobile has opened up the new 4x4 MIMO flashing the APK1 MODEM makes LTS very fast if you're in one if the cities out if 319 total but T-Mob has said by end if year it'll be on their entire network so that number is changing rapidly. I used to get abiut 10-12 upload and download (Mbps) now I get on average 40-80 deoending in where I am in my town and if close to a tower but it's still very fast at home which isn't near a tower so I'm still very happy. I get about 40Mbos each at home and a couple miles away I get double that give or take.

Ok onto the files. First I'd make a backup with the smart backup app by Samsung to your PC so you can restore it later and not have to download all your apps.

Not sure why you can't find the link. I had no probs at all there's a forum for it specifically but here's a Dropbox link if my files. Unzip it and out each file in its Odin slot they are tagged AP,BL,CSC,CP etc so you can't mess up. Just double check. You boit into download mode first so Odin sees the phone if course and this version of Odin is unique to this U firmware so only use the one in my .zip. there was a home.csc file floating around but you don't want to flash anything with home in the file name and has since been removed. It was causing phone to boot into bootloader with an error instead if going into the Android startup process...so be aware but I don't think my zip even has it. It's been a week but I believe I pulled it out.

I will pm you the link in 10 mins or so. I have to upload to Dropbox. And I'll link you to the U thread also. Remember you WILL lose everything you don't backup from your internals sd (external memory card won't be touched but I always pull mine to be absolutely sure. In the meantime you might do your backup...that takes about 20-60 mins deoending in how much date you have internally.

Here is the T-Mobile Edge U forum. Read it all. Some people are doing it in certain ways and certain files I my to be sure they can revert back. I don't k ow if you can revert back if you do every file in the "kit" or not but I've read you can root afterwards but you have to follow the after Odin root instructions PERFECTLY or you can mess stuff up. I'm not rooted and don't care about it so I did the whole process, all 4 files and then flashed the APK1 MODEM afterwards you might be able to flash it at the same time as the ither files I just did it that was because another friend did it after the initial U firmware flash and had not a single issue. My S7 edge has never been faster, everything works like wifi calling, etc. I think you'll lose video calls if you have it but I don't know if T-Mobile even has it and it's nothing I've ever used.

You'll also find the download package there....My computer is doing the win 10 anniversary update I firgot (I was waiting) so you'll get the files quicker from there.

Hope this helps. It's very simple. Just depends if you want to update baseband etc. I did because I don't care if I can go back or nit since I dont care about root. Some are flashing only some if the files to not lose root but that didn't pertaining me so you'll have to read and ask there

Here is what you're gonna do basically but ask any questions at that forum you may have first
