What roms can be used with the T999v?

I've been going all around the forum not being able to figure out what ROMS and kernels will work with T999v Wind version of the S3. I bricked my phone once already by installing the wrong kernel, so I don't wanna mess around again too much without knowing what roms and kernels are working. I've read around that we can flash T-mobile roms as long as they don't contain radio files. I also read on another thread that as long as the boot, modem and amss files aren't in the rom, we're good to go. Now I'm pretty new to the Android community so I'd like some help before I have another disaster on my hands.
Thanks.

*Disclaimer: I am not a Wind user so don't quote me on this but...
I don't believe any of the custom roms in the T Mobile dev forum come with radios. Except for the stock images made to flash with Odin. The main thing to remember as far as kernels go, if you flash a touchwiz rom you need a touchwiz (or stock) kernel. If you flash an AOSP rom you need an AOSP kernel or you will be stuck in a bootloop.
BTW, this rom has been confirmed working on Wind Mobile.

Thanks. Now I had a question about kernels. They still need to be for the T-Mobile version of the phone right? As long as that's true I shouldn't really have a problem using the kernel?

Yes, I believe you will be fine with any T Mobile specific kernels. Still, the important thing before flashing anything is to make sure you make a backup just in case.

That rom will work fine.

I'm on a Wind GS3 and I'm currently using FreeGS3 R5 with Trinity Alpha 19 kernel. Works great.
edit: Just updated to R6, still great.

Flashing a new ROM, with updates

Noob question. I have been searching threads and could not find an answer.
I've been running PH's Blazer ROM v1.6 LG2 with an LF9 modem about 4 weeks now. I am wanting to flash SS's Team VeNuM Odexed Blue ROM, which is currently in v1.4 as of 8/16, because I want to get a taste of an Odexed ROM AND - I like blue
Here's my question:
Do I need to flash the first version of the new ROM, after a full wipe of course, and then flash the most recent update - OR - Can I simply flash the most recent update ROM?
If I need to flash the original first, do I need to flash each update, in sequential order - or can I simply go to the most recent update?
My Sprint SGS3 is my first Android device, which means my first rooting experience, which means I'm currently residing in noobopolis. I appreciate the support from the members of this forum, and their appreciation and understanding of the naïveté of a rooting virgin.
BTW - I am running CWM 3.0.7 & have ODIN3 v3.04. Do either of those need to be updated, prior to flashing?

I see no reason why you would have to mess with CWM or ODIN... as for flashing a different ROM, just flash the newest version of it. V1.4 in this case. Flashing an old version and then every updated version after that would be pointless. New versions are typically issues as a full ROM. Unless for some odd reason the dev is issuing them as small updates and not the full ROM, and I've never seen anyone do that.
If you flash that ROM and later a new version comes out, you can just flash the new one on top of it. Your first flash with Team Venum ROM should be the newest version.

Thank you!

Wonderful, thank you! I figured that was the case, but when you're dealing with an expensive device I'm more confortable performing some due diligence first - especially when the consequence of not doing so can have such a negative impact. My SGS3 is a beautiful device (when outside of my Otter Box Defender), but I'd rather not use it as a paper weight....

Of course, it's always good to get your facts first. As long as you follow instructions you shouldn't have issues. Make sure the ROM is for your device, read comments so you know what to expect etc... Stay informed and you will do well.

Just finished flashing Odexed Blue v1.4, no problems at all. Went ahead and used Team Sonic's Modem Flash tool as well & updated to LG8 modem.
Titanium Backup was a life saver, love that app!

Quick question /how-to

Hi there XDA,
Definitely horrible at flashing and jazz, I have a quick question.
I had flashed JellyBeanv3 rom a while back and today I received the 4.1.2 OTA, now I'm wondering if my phone would brick if I updated.
What would the proper steps be to update? Also, would I be better off using CM10 (I hear a lot of good things about it, just don't know what's so special.)
Thanks,
-Mike

You won't brick, although you may lose root.
If you are fine with stock, then just upgrade to the OTA.
If not, then I'd upgrade to CM. They introduced the latest 4.1.2 upgrades in a matter of a couple days, so you're not lagging far behind official releases. CM includes an OTA updater so you can update to the latest nightly pretty easily.
To install CM, follow the directions at http://forum.xda-developers.com/showthread.php?t=1839882

What's "Jellybeanv3"? A custom rom?
An OTA update WILL NOT work on a custom rom.
If it's indeed custom built, I don't understand how you people are EVEN getting the update message.
If OP is on stock rom (no mods, etc) and talking about JZO54K OTA, then just run the update. If not (cwm installed, rooted+modified system files), read this thread.
About CM, do you think so many people love it just because? lol.
Try it yourself. Like reuthermonkey said, read the nightlies thread/first post, flash away.

Jellybeanv3 was a custom rom that came with awesomebeats, was pretty cool.
I decided against upgrading to ota, and went with cm10. Pretty much godlike in my opinion. The colors on this phone have never been more vibrant.

[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/showthread.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/showthread.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.

[Q] Any official JB ROM here?

I want to flash CM 10.2 again on my Ace II because I'm having some issues with the mobile network since I flashed it from my original Gingerbread. Now I know I need an official Jelly Bean, but they didn't release an update in my country (Bosnia & Herzegovina) so what do I do now? Does that mean that I can't flash CM 10.2 at all without having some problems or is there a solution for me? Will it work if I flash an unofficial JB custom ROM? If yes can someone link me to such a ROM?
Thank you in advance

You can install all JB stock roms for europe and than flash CM

So let's say I take a JB firmware for Germany and flash it on my Bosnian device it will work for flashing CM...maybe I should mention that I have a carrier lock, could that be a problem? Thank u for ur reply

It should work. I flashed a lot of stock ROMs from a lot of countries, and every one of them worked flawlessly. The carrier lock shouldn't cause any problems, although you might want to backup all of your data, just in case.

I can't believe it worked. I've been waiting for months for the OTA update, but I guess flashing was the only solution...now I have an official Jelly Bean and tomorrow CM 10.2 hopefully without any problems. Thanks a lot guys
