[Q] Just purchased a AT&T S3 to use on T-Mobile - Rooting and Rom Questions

As the title states, I just picked up a AT&T galaxy S3. I am looking to use it on T-Mobile. Coming from a galaxy S1, the unlocking procedure is a bit different. It also seems that roms are fairly brand specific, so I assume I should be looking for i747 roms. There are so many options out there, could anyone point me in the right direction to get this phone up and running? Are there any special considerations I should be taking since I am using an AT&T phone on T-Mobile?

Before you do anything, if you want to unlock you phone so you can use it on another network go to this thread http://forum.xda-developers.com/showthread.php?t=2033225&highlight=sim+unlock
You will probably need to change the apn numbers to match t-mobile which is easy.... as far as roms go, you should do some searching for t-moible roms in the development thread. Also not being familiar with AT&T and T-mobile you should check to see if they use the same band and also check which modem (radio) you need... I am sure there have been lots of people that have done this arleady.... search search search at least you asked the question before you started not after you had a wreck

Thanks for the link. I did the unlock procedure, haven't tested it yet since I still need to cut down my SIM card.
I also went through and did the CF-Root procedure with ODIN. So theoretically the phone should be ready to flash a custom rom.
I was under the impression that I should be looking at i747 roms instead of the T-mobile version (i999?) since my device is originally AT&T branded. You are saying this is not the case? Basically I should look at roms in the T-Mobile section? It might not matter anyway since some popular roms run on both.

UPDATE:
I installed Stockorama V2 on the phone and it is up and running on t-mobile. It is a multi-carrier rom, but I used the AT&T options when installing. Would I have better luck installing it as T-Mobile? Basically, can I install a T999 rom/kernel on a i747?

[Q] CM11 ROM question

I have a TMobile Note 3 with 4.3 rooted using RDLV with KNOX 0x0. I am tired of the stock ROM and I want to switch to CM11. Here are my questions:
1) What's the difference between hlte and htletmo versions?
2) Can I use the htle version since it is being updated more often?
2) I came to Note 3 from an S3. It looks like there were more CM stable versions for S3 and Note 3 only ever has had night-lies..why is that?
3) With reference to the question above, How will that affect development of future versions of CM?
4) Will T Mobile's wifi calling work with CM11?
5) If not, which ROM would it work with and is it safe to use that ROM?
6) Which is the most maintained/updated/used ROM for Note 3 apart from CM11?
Thanks
PS: I have gone through the forums to the best of my abilities to find answers. Please forgive me if I missed one and don't forget to point me to the thread with the answer

I've been pouring through various forums concerning the hlte and hltexx, etc stuff. and have found no definitive answers either..
I'm new to the note as well coming from a string of other devices, honestly this stuff is kind of a headache.
I still haven't found anything very useful.. but what i've gathered is that hltexx seems to be the most common thing across ROMs that should work on our tmo variant..
but if you read this: http://www.cyanogenmod.org/blog/unified-builds you'll see that we will have to flash hlte versions, at least for CM.
Seeing as you want to flash CM, you'll probably be okay flashing the hlte version.
I have no idea if that's a CM specific thing or if it's being adopted across the board by various devs..
it seems that no matter what you do, it might require editing out the device check line from the updater-script,
just like from some ROMs for the S3 (haven't used that phone in a long time, though, so don't think that's a current issue, anymore.)
aside from that, I can't answer any of your other questions, as I haven't flashed any custom ROMs for this device, yet.
but, if this phone is like any other tmo phone, you'll lose wi-fi calling if you switch to any ROM that is NOT based on the stock ROM that was shipped with the device.
i.e. no AOSP or CM based ROM will have wi-fi calling. there are always alternatives to wi-fi calling though.

Thanks for the answer.

1) HLTETMO are the old non-unified builds. HLTE builds are "unified," and will work across networks, as far as I understand it. What this does is get more developers on the project for everybody since these devices--aside from very minor differences (I'd imagine the RIL, but I could be wrong) between Note3 devices.
2) Yes. Use the HLTE version. I'm pretty sure HLTETMO is dead...and that's a good thing. Things were a little buggier at first for the unified builds, but, they have gotten much better much faster and are currently better than the last TMO builds.
2) See above
3) See above...I can only speculate but I imagine that will concentrate the developer pool that works on devices. Instead of 4 (or more) disparate HLTE (or whatever device) teams of devs they will now all work together. That can only help things along. Again, only speculation. Time will tell.
4) I, personally, don't care about that feature but I do recall seeing some HOWTOs on WiFi calling on CM. But I highly doubt that will ever become a part of the build. That's not a concern of CM. They have enough things to worry about.
5) I'm an AOSP only kinda guy so I don't actually know, but, I'd imagine any TW based ROM will work fine with WiFi calling.
6) See #5. I wish I could help you out on this one, but, I can't. I'm an AOSP only kinda guy. The first thing I did when I got my $700+ phone home was invalidate the warranty. Knox? Pffft, whatever. Right now I can assure you that CM11 is in a highly developed form. It is daily driver status, IMHO. All the major stuff works and works well...and performance is top notch...especially with the ART (Android Run Time....screw Dalvik). Battery life isn't as good as TW roms, but, it isn't far off. The only thing missing is S-Pen features, but, there is another thread around here that gives you step-by-step instructions on how to recreate the utility of the stock S-Pen features.

[Q] ROM

Just retired my Tmobile S2 / Jedi Mind Trick and purchased a new Tmobile S3 LTE. Just rooted it and put on CWM.... Which ROMS have the following.
1.WiFi Calling and MMS
2.Good Battery Life
3.Silky Smooth and Lighting Quick
4.Plenty of Free Memory
5.Bloatware free
Thanks

All Roms based on the Samsung Touchwiz Framwork will support WiFi Calling. So try S3Rx by @enewman17 or StockMod by @saranhai. Eitheer way, I suggest flash KT747 Kernel for Touchwiz.
In my opinion, (and this can be debatable.) AOSP Roms have more free Ram and slightly better battery life. However they will never support WiFi calling. Let me know if you want to explore that.

I found this thread in search before asking the same question.
Not all touchwiz based ROMs support Wifi calling. Read posts 31 and 32 in this thread. http://forum.xda-developers.com/showthread.php?t=2735506&page=4
I am having a hard time finding the best ROM for my needs. I have to have wifi calling. I have tried several, and really like the KitKat based AICP, but that doesn't do wifi calling, so I started looking for Touchwiz based ROMs, but can't find a good stable one that works well FOR ME.

To rephrase Perseus' statement, only Touchwiz roms based on T-Mobiles firmware will have wifi calling.

Yup. That makes it far more difficult to sort them out.
I am going to try out StockMOD Rom now.

Most TW roms are built from a tmobile base. If not it should specify [PORT] in the title and/or OP.

I can now confirm that wifi calling works on StockMOD.

Hi, I am new here to trying to figure out how to enable mobile hotspot/tethering and wifi calling with my SGH-T999L(t-mobile, prepaid 5GB data).
My phone(ver. 4.3) is rooted by Odin method with root66_TMO-L_T999LUVUBNC1.tar.md5 file. And superSU(ver. 1.94) was automatically(?) installed during the rooting but never used it since. Anyway, this was my very first dealing with phone software; I have never experienced rooting/flashing before. Please bear with my ignorant terms and questions...
q1. Isn't there any reasonably safe ROM to enable tethering?
q2. Can I flash the custom ROM with Odin, same process as my rooting but just change the MD5 file?
q3. Do I need to configure my phone before or after the custom ROM flashing for tethering?
when I rooted, I did not make any recovery. I had no clue about Knox counter before and still don't know where and how to check Knox counter with my phone.. I have just followed YouTube "safe rooting methods for s3" without much knowledge. How lucky my phone is not a brick now!!

1. Any of the Custom AOSP Roms will have tether built in. If you want to keep stock Touchwiz, you will have to use some Tether app from Play store.
2. Yes and no. You first flash custom Recovery with Odin. Same process except different file. Then you flash custom roms (which are in zip format) via the custom Recovery. A custom Recovery is TWRP, CWM or Philz Touch.
3. Usually yes after the custom rom is up and running. Just a few click to turn it on or customize to your preferences. No Rocket science there.
Knox Counter or Warranty Bit is displayed when you put the phone in download mode. If its zero that means its not set. If its 1 then you tripped it.

Is there any Tmobile based TW ROM that has HALO? If not, is there a good add on or app for notifications? Halo was one of the things I really liked about AICP. It seems possible, as Slimbean says it doesn't include HALO by choice.
It seems that all the ASOP ROMs are KitKat. Since KitKat is on the way to Tmobile S3 at some point. When that happens, will it allow ASOP type ROMS with Wifi, or am I mixing up several concepts?

HALO is a feature introduced by AOKP Developer community. Hence it is found only in Roms that are based on that code base such as PAC MAN. Other ROMs particularly Stock touchwiz will never the feature as is. Samsung did introduce something similar called floating Notifications that some liked but most did not. They base on Google's code so the AOKP code will never make it into Samsung Stock. However, I do recall there was bounty on Verizon's forum for bringing HALO to Touchwiz. Don't know what happened to it. I don't use touchwiz.
Speaking of all these terms, you indeed are mixing quiet a few things. AOSP Roms, based either on Google's code or CM's code will never use anything from the AOKP fork. This is by design. If you want to know why, you will have to understand the difference between AOSP and AOKP. Google is your friend.
I recall Liquidsmooth at one point in the 4.3 code had introduced HALO. Don't know if it continued or not. I do know, with the significant code changes to Kitkat, these prior features are not working and the developers are working to port them over. Its a matter of time. Speaking of which, all Custom Roms do have a 4.3 variant. Its just that users want the latest and greatest so you won't see much discussion of the 4.3 now. But it sure does exist.
After you accept Stock Kitkat update, I am sure you can continue to flash custom Kitkat Roms. Who knows, they might have moved to Key Lime Pie by then. But I don't think I understood the question. Are you referring to the Tether or WiFi hotspot ?

I was referring to wifi caling. That is a make or break feature for me. I found a few ROMs that were head and shoulders above TW (FOR ME), but because of lots of steel and concrete structures in my AO I really need wifi calling. I looked into multiboot, but I would have to toggle back and forth too much to make it work.

Wi Fi calling can and only will work with Samsung's Stock Touchwiz. So since that's critical to you, I'd suggest sticking with the stock Rom and Root it if needed. Once Rooted you can remove the bloat to make it more viable. You can also use the KT747 Kernel for Touchwiz. That will allow you to get better battery life.
As to your HALO wish, I guess, you'd have to stick with floating notification and Multi Window features Samsung has. You could try some of the ports of Xposed frameworks. But be cautious to make sure it does not break something else.

Thank you very much. :good: Really sorry to bother you but more Qs..
1. When you say stock Touchwiz, does that mean the file I flashed for rooting? root66_TMO-L_T999LUVUBNC1.tar.md5
I have also tried many Tether apps found from google store and none of them worked. They just brings me to T-mobile error message.
2. Beyond tethering, I also like to have WIFI calling function although wifi calling is not as important as tethering for me. Benz said StockMOD works for WIFI calling. So, I was thinking about to flash StockMOD for my custom ROM as long as it will also work for tethering... Do you know whether it works for tethering? If so, would you tell me where I can find StockMOD? By the way, is StockMOD a custom ROM?
3. Did I really screw up my phone warranty? Ouch,,, I have just checked the message on download mode of my phone. It says following:
product name: sgh-t999L
custom binary download: no
current binary:Samsung Official
System Status: custom
DualDomm Secure Boot: enable
Warranty Bit: 1
Bootloader AP Swrev: 1
Any unusual status you notice beyond warranty Bit? Is this saying my phone is rooted? Frankly, I am still not confident to say my phone is rooted.. AGain, thank you very much for your help.:good::good:

Touchwiz is the name of samsungs launcher and modifications they made on top of Android. So whem you see stock, tw, or touchwiz its referring to the official firmware from samsung. Touchwiz based, tmobile roms are the only ones with wifi calling.
The warranty bit is tripped. No way around this if you plan to flash anything anymore. But yes, your warranty is now void im afraid...

[Q] Looking for the right 4.3 and/or 4.4 ROM

Hi, a nearly noob question.
I have Galaxy S33 T999L with SlimKat, android 4.4.4, baseband AMB7, but I believe it doesn't have Wifi calling. I use Teamwin v2.8.4.0 recovery.
I am looking for any good stable ROMs that are:
1. Android 4.3 or 4.4 with 4.4 preferred
2. Wifi calling build-in
3. App Ops provided, OPTIONAL, (for permission control on apps)
4. As lean as possible, but useful features are welcome
Some of the threads are over 3 pages here I did jump thru a few, still kind of lost since these threads started in 2012.
This is my back up phone returning from a loan to a friend. I am not using it now (no SIM inside), just trying to UP this phone before I can reuse it again (Been using Avant for a few months now).
I would appreciate anyone can post a link, or share some advice on which ROMs you would recommend. Many thanks,

For wifi calling to work you will need to stick to stock based ROMs so eliminate all others and then try out a couple of those to see if they have what you are looking for.

[Q] I9505 Lollipop on SGH-M919 or impossible

With Lollipop 5.0 available for international variants such as the I9505, is it possible to simply flash that official rom, along with a U.S. modem to the SGH-m919?
I have read threads where CUSTOM ROMS are compatible with both the I9505 and M919, but not the stock I9505 rom already available.
Am I missing something obvious with this question because I know I am not the first to think of it. After comparing hardware specs of the two models, only the CPU looked different.
Has anyone successfully done this or has anyone done this and then needed a dozen workarounds only to get below par functionality? One of the reasons that I have not flashed to all of the current custom roms, is that each has "no Bluetooth support yet" or "Wifi calling not working." I truly respect the work of the modding community, as I can not do what it does, but I just do not want any more never ending workarounds simply to makes calls and texts. Flashing a rom? Yes. I run both T-Mobile and Metro versions of the latest M919 firmware/software.
Thanks much.

Bluetooth worked for me. WiFi calling will not work either way, no matter how official. Needs to be T-Mobile firmware. I think there is a guide to flash it in general thread if you're interested. I wouldn't do it

Thank you very much. I have spotty coverage where I live. I go from 4G LTE to no signal 20 feet from my house. I wanted to try Lollipop without using a custom, buggy rom. Many of the custom roms look fantastic and feel snappy but the list of "not working" and bugs to be fixed in next build is simply not worth it to me.
