[Q] Differences between E971/E973/E970 in terms of ROM compatibility - LG Optimus G (International)

Since all three variants for the North American market are so similiar, are the ROMs also cross compatible? For example, can I install a rom for the ATT E970 onto a Rogers E971? or are there significant changes needed?
I saw one comment where the poster says they do it all the time, but that's the only comment I could find.

ATTENTION CANADIAN USERS: Forums for Canadian carriers

Hello fellow Canadian GSIII owners: please see below and note which forum you should be looking in for ROMs for your devices:
AT&T forum: SGH-I747 (AT&T, Rogers, Bell, Telus and SaskTel)
T-Mobile forum: SGH-T999 (T-Mobile, Wind, Mobilicity and Videotron)
Sprint forum: SPH-L710 (Sprint only)
Verizon forum: SGH-I535 (Verizon only)
Developers, please put carrier support in the title of your threads. Thank you!
---------------------------------------
Hello XDA,
Can we please get an android development forum for Rogers, Bell, Telus and Wind? Rogers/Bell/Telus phones are SGH-I747M and the Wind version is the SGH-T999, but they all have different basebands and stock ROMs. Trying to put Canadian threads in AT&T and Sprint forums will result in a big mess.
Alternatively, instead of separating by carrier, separate by model number. Keep all the I747 development threads in one forum and T999 threads in another. Then people can put the carrier into the title of the post.
Just something to think about.
Thanks!
I agree. But AFAIK, the Wind/Mobilicity/Videotron S3 is the same as T-Mobile's, not Sprint's.

Indeed it is. I stand corrected.

and the Rogers is the same as AT&T's
historically Rogers and AT&T have been interchangeable in almost every aspect on all the devices they shared. Rogers uses the exact same frequencies as AT&T, and the devices are the same aside from some minor differences in bloat, lte toggle, and native wifi tether
What about the Telus, does that fall under at&t also?
Thanks
I agree very hard to follow on what is for which phone, not going to take any chances until things are a little more clear. Still have the old S1 to mess with.

AT&T, Rogers, Bell and Telus have the same phone, the SGH-I747. But just because it's the same hardware does not mean it's the same software. It may or may not have different basebands and certainly has different carrier customizations. As Pirateghost mentioned, AT&T removes some features in its ROM (software), the most important being, at least for me, the ability to tether. So if you flash a rooted AT&T ROM on your Canadian device, it will most likely work but you will lose features(!) That's why we need to be very clear about what carrier each ROM is for. Furthermore, if you flash the wrong baseband (i.e. flash a Rogers baseband on a Bell phone), your phone may not work as a phone or it may connect to the wrong network and you will be charged roaming fees. At the moment, I can see that AT&T has a different baseband version from Bell, but Rogers and Bell seem to have the same baseband version. Are they interchangeable? I have no idea. Anyway, it's better not to mix these things up. That's why separate forums are a great idea.
As a SaskTel customer coming from the international i9000, these forums are very confusing and not very organized. I would definitely support more organization.
I guarantee that you won't roam on the other carrier if you flash the wrong baseband (Telus/Bell/Rogers). They don't have roaming agreements in place to allow that. That's why you won't get service with Rogers in some areas where Bell does have service.

That is how it was with the i9000. If I flashed the wrong baseband (for example, a US modem that did not support 850 band), I would just have no reception when I left the city.
Sasktel, Bell, Rogers, Telus all have the AT&T version with tethering left in.

OK. Either way, flashing the wrong baseband is a bad idea.

Except this time around, it seems that there is a slight difference between the two in terms of software, and enough so that I've read posts of people having issues when using at&t based stuff on their rogers phones.

I've been here before with the vivid, skyrocket, and the one x. You can ignore anything I say but I HAVE dealt with this stuff before.

So is it safe to say that you can flash the Stock Rom or Custom ROMs for T-Mobile T999 on Wind Mobile's T999V. And at most you lose Roaming and/or a few features?
I already see that there is one or two ROMs that are confirmed for multiple carriers.
A dedicated Canadian Forum is a great idea! There is so much information floating around out there with the multiple variations of the sgs3.

As a Rogers user (and relatively new to Android) it freaks the hell out of me to flash custom ROMs based on the AT&T version, because I'm sure I *will* lose tethering and the ability to turn off LTE.
That's the stupid thing - it'd be rather simple to have subforums dedicated to the canadian devices, because the software is different (not only the bloatware, but apparently some more stuff too) and the baseband is also different, which could lead to problems down the line, no?

If a rom is done the right way you won't lose any functionality. You can't honestly believe that at&t users don't want those features. I prefer to build all my roms from a rogers base for the simple reason that it is less work for that functionality.
PS. Any rom dev should know better than to force a modem/radio/baseband change on their users.

That might be true but if you check your firmware versions, they aren't the same as AT&T's.
Also, I have flashed most of the international radio's on my older I9100 and never had a problem in Canada or US when travelling. They may not be customized for that country but they do work.
I PMd one of the mods with a link to this thread. There seems to be interest in a forum for Canadian carriers, so let's see if we can make it happen.
By the way thanks to everyone chiming in with their two cents. I am not a developer, and although I've been around xda a while, it was always as a user. I''ve written a guide or two on how to root and flash devices, but it was always based on other people's work. So I am learning all this as I go along.
I come from the desire z/g2 forums. G2 is t mobile, The desire z is run on multiple networks globally. Baseband are set by the phone, not the radio (I think that is the same thing as a modern?). On my Desire z running on Rogers, I flashed T-Mobile radios and international radios which worked on Rogers no problem.
Features of a rom are determined by the dev, if you don't like something, flash something else or restore your nandroid backup. Read the op and ask the dev if you are unsure about any features on a Rom.
I would think the only models that should be separated in forums are the international version, totally different processor and maybe Verizon cdma. From a sheer volume of users standpoint, further division is warranted. You think this is bad, wait until Verizon and At&t widely launch, this current setup will be complete chaos.

[Q] Question for the Mods

Once all variations of the Note II are released will the forum become a little more organized and divided as to find the right info for the right model of phone? I have only ever had phones that were exclusive to one carrier and didnt have to worry about flashing a ROM from another carrier or different version of the phone. Will it even make a difference? I know the US LTE model is what N7105 and the international model is N7100 so I am assuming that flashing between the two could be a no no?

[Q] N7100T specific development?

I currently have my Note 2 on its way from my carrier, Telecom NZ. But its a slight variant from the standard N7100. It'a a "N7100T" the difference being it has the 850MHz 3G band. I believe Telstra AUS has the same one.
I'm no stranger to rooting and flashing custom roms, but I'm a little confused as to whether I will have to use roms specific to my variant of the phone? Anyone else have this same Note 2?
Historically, the T variant just indicates optimised support for the 850mhz 3G band, and software for the non-T variant works fine. Given this is the first T variant to launch, it may require a little caution - but it's unlikely be a variant of the N7105 or anything. Best practice to wait until a download of a stock build is available before tinkering too much. Watch out for fast dormancy settings on N7100 ROMs if you value battery life!

Thanks for the reply.
I was browsing through SamFirmware and noticed the Vodafone note 2 is showing as the N7105. I'm curious, what carrier are you on and what model do you have exactly.
There one other ROM available for NZ and its just listed as "New Zealand" but is for a N7100. So I'm assuming this one to either be for 2degrees or Telecom. Kind of confusing myself haha
UPDATE
Okay so I got the phone. LOVE IT. Just came from an iphone5 so quite a difference but I was on an S3 before that.
Anyway, I found the stock rom on Samsung-Updates.com so after a bit of browsing the dev forums I'll start to tinker.
Any update on this post? I too have the N7100t and was looking to upgrade to 4.1.2 but can only find it for the N7100.

[Q] What are the different varients?

Pretty simple really. What are the G2 varients. E.g. Which model number is unlocked international? D800? D802? Which on is T-Mobile? At&t, sprint, etc. Also, besides verizons, are there any differences between international and T-Mobile versions besides carrier branding and bloat? Thanks!
Hate to be the"bump" guy, but I really want to buy this phone. I just need to know which to get...
There used to be a nice chart here:
http://en.wikipedia.org/wiki/LG_G2
But it seems to have been changed (I would say updated but there are less models there than before, e.g. the D803 [Canada] is missing and so is the D805), and there is no longer a chart.

asop custom roms? and custom roms on verizon?

I understand the device works on Verizon but am curious if all custom roms will support the bands verizon requires? I am guessing that the modem is complete (works through and through) for all bands but not sure so am wondering if separate roms will need to be created for the network (really theirs only one, verizon) that uses different bands. I would love this device running Liquid Smooth or similar on verizon!

This shouldn't end up being the case as custom ROM's will use the Nexus binaries provided by Google available to developers which will support all of Verizon's band so no need for a Verizon specific RIL implementation for example. As a result you will be fine to run AOSP based ROM's such as Liquid Smooth. The thing for ROM's will be more about whether you have the American model of the device or the International model. Let me me know if you still have questions!

If your going to use it on Verizon, I would recommend going with the North American model which is model number LG-H790 for US carriers. Both models will have a great selection of custom ROM's and goodies, and with only minor differences between the two models the hard working developers won't need to do to much extra to support both.
