Suggestion: Merge GT-N7105/SGH-T889/SGH-I317 Development Subforums

Based on my reading and testing it seems the GSM LTE variant Note 2 ROMs are cross-compatible with the exception of the radio. That is, flashing of SGH-T889, SGH-I317 and GT-N7105 ROMs among one another works perfectly as long as you have the proper radio flashed as well.
I propose that the SGH-I317 and SGH-T889 Development forums cross-link to the GT-N7105 development forum, much as the Accessories forums of all Note 2 variants link to the N7100/N7105 Accessories forum.
In order to avoid potential confusion, developers could tag their threads as [N7105], [I317], and [T889] to designate the device the build was developed for and tested on. Users would then also know whether or not they would have to flash their respective radios after installation.
This will foster greatly expanded and accelerated development for the GSM LTE Note 2 variants. Developers will benefit from the inherent similarities of these devices (as they are more similar than different) and users would have greater variety.

So you are saying you can run a custom rom from a t889 on a i317 and just flash the modem with whatever flavor you are using...So I can use a i317 with a t889 rom and flash a t889 modem on it and put my tmobile sim in the thing and all will be good right?

Looking for more feedback and confirmation on this as well!
Update, I flashed the i317 pacman rom on my t889v wind mobile and its working great

In most situations, the ROM's zip file won't even contain a modem file in the first place, so you don't need to flash any radio afterwards. Maybe RIL files or carrier-specific CSC settings on TW ROMs, but that's another matter altogether, and not something that would typically preclude your phone from working if you skipped it.
In the T889V's specific case: do not flash any modems in any circumstances unless you are ready to deal with the consequences. My thinking is that there's a bug somewhere that leads to NV item corruption instead of just plain bootloops like on other variants.

Thanks for the response. By modem I assume you mean modems other than ones designed for my variant? I flashed the latest Wind Mobile modem from 2013 as I had the one prior to that.
Everything seems to be working fine, so I am happy. I was just apprehensive about flashing a rom designed for another phone as I do not fully understand what each contains, and if it would conflict with my phone.

Yes. Although in some cases, even reflashing the original T889VVLALJ4 over itself lead to problems, but that's a moot point since you're running T889VVLBMA3 already.
As for as the zip's contents, you can see for yourself by checking the files themselves and the updater-script file. And of course by checking out a given ROM's thread.
Back to the original topic, I'd be okay with the proposed merger.

Is this still up for consideration? Ever since getting the T889, it has only been hinted that there may be some compatibility. Merging the forums where proper would make it clear what will work and what won't.

I have a big question
Hello everybody, can I use the ROM of a GT-N7105 in the SGH-T889?
I need a stable rom for my Note 2 SGH T-889 form T-mobile

THE RADIO IS FOR THE WIFI? I have 7.1.2 installed but no wifi connection the wifi worked in the beginning of the installation then just stopped working

[Q] Has anyone made a simple to flash MEA rom for t-moble?

I was wondering if anyone has made a simple to flash MEA stock style rom for our T-moble S4? I get the idea that you can flash the international version and then a kernal etc. But what about a single step ODEN flashable rom based on the MEA. The reason im in such a rush for it is the audio issue im having with my favorate headphones. I have also yet to find a step by step guide for getting the MEA firmware installed and working. Any ideas, or am i just missing it somewhere?

You are not doing a good job at searching. There are threads about installing 9505 Int & other carrier ROMs in here.
I'll give you a few hints. Do not flash MEA Odin firmware, flash custom ROMs based on MEA. Either find directions in here or at other S4 carriers forums.

Thats where the confusion was for me. That hint put it all together. I did read the thread about flashing other carriers ROMs and just didn't put the two together. I was about to flash the MEA Odin firmware but got hung up on the fact it was not rooted. Now I get it!!!! THanks!!

4.3 Ported roms to t-mobile data loss issue

Hi guys i need some help from you guys and developers . As we have 4.3 roms ported to our device by very great developers but we all are facing data loss on these roms. when device screen goes off for few minutes and while making screen on i see no data connection on my device . Problem i came to understand that its a modem issue because 4.2.2 modems are not compatible with 4.3 software . my question is that can we safely flash modems from AT&T SAMSUNG GALAXY S4 OR I9505 devices . All roms and kernels of AT&Tand i9505 devices are compatible with our device. In past on my galaxy s2 T-mobile device i flashed modems from AT&T variant and they were working fine. may be this can resolve our data loss issue
Thanks for your help and advice ....

I believe that this time around the modems can't be flashed from different carriers correct me if I'm wrong

Not without breaking the phone, you are correct.

In past on my galaxy s2 T-mobile device i flashed modems from AT&T and verizon variant and they were working fine. It was the same issue when we upgraded . This was the solution to resolve data connectivity issue . And some developers also modified the modems to resolve the issues on Galaxy s2 to make them compatible .That's why i tried to share my past experience . But now we can not go ahead with this problem until we do not resolve this issue . we do not expect any update from T-mobile for our device in near future . only developers can help us to resolve hardware and software complexities .

Here is the deal, NONE of the custom zip file roms found here in XDA which we flash contain "MODEMS/RADIOS".
There is a good reason behind why they don't have modems. (brick at worst and soft brick at best if we flash modems)
The only firmwares/roms which contain MODEMS are those which we flash using ODIN, like stock roms which
are specifically designed for our M919 Tmobile Galaxy S4 phones and no other models.
These zipfile cwm/twrp flashable tmobile/at&t/i9505 roms for the most part can be interchangeable especially
if we flash a proper kernel for our specific phones but if you flash MODEMS you are just asking for a lot grief.
Good luck! (you just might need it)

I was just asking because it was possible . i was using galaxy note radio on galaxy s2 t-mobile SCH -T989
In this thread you can see galaxy note T879 radio for galaxy s2 and telus radio which was canadian variant and blaze 4g radio for galaxy s2
http://forum.xda-developers.com/showthread.php?t=1895400
I used galaxy note radio on galaxy s2 . i do not claim its my idea but i give credit to those developers who made it possible on galaxy s2 when it was upgraded from gingerbread to ics. i am not like others who steal others roms and claim their own .
I was seeking help from our developers to look into and tell us the possibilities.

T-Mobile devices support different LTE bands than other carriers and the i9505, which means our hardware is different, specifically the modem. Pretty much everything else is the same, which is why we can run other carrier roms. Radio comms are another beast though...not saying it couldn't work, but its much lower level than the OS/ROM is.

T-Mobile Galaxy S III LTE (T999L) custom rom

Hello, I am trying to find a custom stable and fast rom for Lte T mobile Lt version of S3. Thanks for any infos.
I mean that I want use LTE. thx

Any rom in this forum should work fine. Aside from the 4.3 rom I just posted, I dont believe there are any roms built from T999L firmware.
Please read the Q&A thread for more on the T999L. Nearly every question you may have is likely addressed there already.

Don't think so. Anyway thx.

[Q] ROMs issue

I have an AT&T Galaxy S3 with Android 4.4.2. I used Towelroot to root my phone and it worked really well. My only concern is about which ROMs to use. It looks like most ROMs for the S3 are for android 4.3 and not what I have. Since I used a root technique for an S4 does that mean I should use ROMs from the Galaxy S4 4.4.2?
Any information would be great. I do not want to brick my phone!

NO. You must stay within the roms for your device. Flashing anything else is highly likely to give you a brick.
You have already started out on the wrong foot; these forums are for the Sprint S3, not the AT&T variant. Look for your device forum and you can flash any rom listed, regardless of whether the rom is 4.3 or 4.4.2 based
