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.

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.

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.

I just got this baby unlocked, FINALLY, and was wondering if I need to flash any modem/radio to get the best possible performance.Thank you all for your awesomeness!
I don't think there's any specific modem that would work best under those circumstances, particularly as modem performance seems to be location-dependent; if you're curious, you could just cycle through all of the available modems and see what works best for you in your area.
I believe you're in the wrong forum. This is the forum for the i747 Galaxy S III.
If you're on T-mobile, you'd have the T999, which is in a separate forum over here
The differences are the T999 doesn't have an LTE transceiver and the radio uses the AWS band rather than the PCS band for HSPA.

...which he unlocked, and now wants to use on the T-Mobile network. This does not mean he has a T-Mobile device.
I am asking if there is a way to make my galaxy s3 i747m useable with wind mobile. Im asking because I remeber that with the Galaxy s2x from telus and I believe rogers you could flash a t-mobile rom and be able to us it on the wind network. I am wondering if anyone has tried this? and what happened.

It sounds doable. If the phone is compatible as is, you may just need to unlock it to get it to work. You may need to try some different modems though.
There is some guy on kijiji that does it for 20 bucks. Yet I have no clue what he actually does lol

Simple answer Yes but it's very annoying to do.
The device itself 100% supports WIND's Network to it's fullest BUT the SGH-1747m has the bands required Specifically the 1700Mhz disabled in the NV RAM

One you follow that and reboot you will be on Wind's Network... but at least for me every time it reboots I lost access and the NV RAM resets...
What I want to know is there a ROM out there or a way to permanently rewrite the NV RAM so I never have to do this
Samsung is putting responsibility for this 'disabled feature' on the Telecom companies saying it is up to their discretion on what bands they allow. Yet bell is saying that it's up to Samsung one which bands are allowed as Bell does not do any modifications to the NV RAM. Whose telling the truth who knows.... Samsung did hint that it is possible to put permanently enable the baseband (but I would have to speak to bell) Now the funny thing is if I give Samsung the IMEI of my device (which was purchased at a Bell location) Samsung is making a statement that my SGH-i747m is NOT a registered Canadian Galaxy S3... and it MUST be an international S3.... Yet bell has it as it was originally their's and Sold by them and originally activated on their network.
I don't know why but I feel like the SGH-i747m's have some hidden backdoor deals with them has anyone tried to install Wind or T-Mobile ROMS from the T999L to the SGH-i747m and if so was it successful? or is there a Custom ROM that will work?
Just a *bump* to this, if there is any way of not having to plug into a laptop to reflash the NV to re enable functionality with wind will someone please share? I've read of some people having scripts that run in busybox or other similar type areas
Can anyone please share with me said script and walk me through the necessary means of implementing it correctly so my girlfriend stops whining at me every time her phone dies demanding I fix it, even though I've offered to show her how to click the mouse twice and do it her self.
Hi,
Is there a way yet to make the 747M fully operational with Wind Mobile? Seems like SOMEONE should be able to figure this out for us.
In your guys' opinion, if I flashed a ROM for the T-Mobile device, whats the worst that could happen? Soft brick or hard brick?
Would flashing a T999 modem be enough?
No Wind network after restarting my galaxy s3 (i747)
Hi, have you yet figured out how to permanently rewrite the NV ram on a galaxy i747 so that the phone recognizes the Wind network even after the reboot? Thanks in advance.
I haven't. I ended up getting an S5 through wind.

Because I'm looking to buy an S3 and the only ones that are selling used around here are i747. I want to use it with Wind Mobile which uses the T999 because they use AWS frequencies.
I747 baseband doesn't support AWS.
If you're planning on using Wind, stick with T999/T999V

As I already stated, the i747 is the only phone that people are selling. Also, the i747 has the hardware to work for Wind Mobile technically because it uses AWS for LTE in my region. It may very well be possible to install the T999 baseband/modem to an i747 to use AWS for 3G voice communication. I've ready about it working for the S2 between the LTE and T989 versions.

I read your post. I know what you stated. I was simply reiterating what you've obviously read on a hundred other threads: they have different baseband and modems, some have different portions disabled per each carrier model. What you've also discovered is that everyone asks this question but there is no confirmed response because no one has actually tried it. Either be a pioneer and give it a shot, just keep wondering or buy a T999. Lots have been asking your same question since the phone released last June but not a single hero

It may have worked with the SII and some other models; maybe it will also work on the i747 in the future. But for the moment, work is still in progress. A complete modem switch that sticks after reboot does not work as of now for the i747.

Hello,
Has a T999 modem been successfully flashed to a i747m yet? I'm looking to switch to Wind Mobile but dont want to have to buy a different phone just for that.
A couple of questions...
I'm thinking about a Galaxy S3, and had a few questions. Looks like there are a bunch of different variants, and I'm not sure of the differences (or if it matters). I'm using simple mobile, and am looking at both the t999 and I747 for AT&T. Any significant differences? Are they both sim unlockable? Anything else I need to be aware of?

Id suggest the T999L. (Its the only one they sell now). It is compatible on more frequencies/bands than the I747, and if you use it on T-Mobile's networks, it has the potential of being twice as fast as the I747. (I747 I believe can only work on the slower of the two LTE bands used, while the T999L can work on both).
They are both unlockable, but the T999L was patched against our unlock method prior to its release. So you either have to get the code from the carrier who sold it to you, or pay someone $5-10 online to do it for you.

Thanks for the info. Looks like the T999L is going for > $100 more than the other 2 on ebay. Not worth it to me. Also have no idea what speeds simple mobile provides. Any difference between the standard T999 and I747? Are you saying that the I747 has LTE capabilities, but the standard T999 doesn't?
That is correct. The T999L replaced the original T999 when T-Mobile rolled out LTE. None of their devices were LTE capable before, because they couldn't use it.
I will say that the I747 using LTE on T-Mobile s networks, may still not get quite as good as even the old T999, if your in an area that has hspa+42. No idea about simple mobile and what they use though.personally, I think either T999 variant will be superior to the I747 when on T-Mobile networks. There are threads where people are trying to force the I747 to use different frequencies because they want better speeds than what they are getting.
And again, there's just no way to know for sure with SM.

OK. Doing some more research--lots of info out there. Seems that the difference between the T999 and i747 is that the T999 has support in the 1700 band for HSDPA, while the i747 has LTE capability. It appears that T-Mobile is migrating away from the 1700 band in favor of LTE. This chart includes LTE coverage for a bunch of cities, including pretty much anywhere that I spend significant time.
This article indicates that SM should operate on LTE. So, from this info it looks like the i747 might actually be the better option--although I think that either one will work fast enough for my needs. Basically, most anything faster than EDGE is fine for me.

Just a bit of an update. Got the 747. Getting 9 mbps download speed, which is the same as my wife on the t mobile network (I don't know if hers is lte or not). So, success.
