[Q] ??? - Galaxy S III Q&A, Help & Troubleshooting

I have the SGS3 preordered from verizon. Are the roms, kernels and mods available for the international version able to be flashed to the verizon version? Had seen a post of it not working with other carriers just want to make sure.

No. They use different SoCs. The T-Mobile, Sprint, and AT&T roms will probably work after a few changes are made, just like the Sprint and Verizon nexus.

AT&T Galaxy Note on T-Mobile(with 3G) Discussion

As everybody knows the At&t version of the Note will be using a qualcomm chip. Now i know the chip different compared to the skyrocket but i was wondering you guys think its possible to flash the Tmobile Galaxy S2 modem and get Tmobile 3G service.
Reason why i asked this because the Skyrocket and Tmo GS2 are similar in nearly every aspect except that they both use slightly different chips i believe. But there software and modem can be interchangeable. So i was wondering if the same possibility can happen on the Note.

Difference thats the unlocked version which doesn't have similar hardware to the the GSM US GS2, and if trying to flash would brick the Note. Unless you start from scratch which is a hassle. The AT&T has similar hardware to the GS2 in US so the modem switch wouldn't require much work besides a simple modem flash i believe. This is due to my experience with the Skyrocket and the Tmo GS2.
Any other thoughts on this? I'm on T-Mobile and will gladly give up my int version for the at&t one.

Typically AT&T version will have even less 3G band support than international version. For example, GS2 international has quad band 3G while AT&T i777 only has triband 3G.
The chance that you will see 3G on T-Mo on AT&T Note is close to zero. That's the price you pay for chosing T-Mo.

The At&t Note has nearly the same hardware as the Samsung Skyrocket.(which does support T-Mobile 3g) All that needs to be done is flashing the t989 radio.
I suppose only time will tell if it will work on the Note also.

Well its 749.99 off contract, right now idk if its worth it since in 2 months the SGS3 is coming out due to rumors. Well so far everything lines up the Gnote seems to have the same internals of the GS2 so the modem will most likely to work.

Not sure if you mean a stock Skyrocket but when I used my wife's T mobile SIM card to unlock my skyrocket it got edge for data not 3G. I think this is harder than it sounds. Hopefully someone can get this to work.

What he meant is that Skyrocket uses the same Qualcomm chip as T-Mo GS2. All you have to do is flash the T-Mo GS2 modem. Since there is no T-Mo GNote, you will have to take the risk to try T-Mo GS2 modem youself which may or maynot work and may brick your phone.
There also could be differences in attena design that may not work the best for 1700Mhz AWS band.
I'm suggesting a good rom/kernel/radio combination for the att note. I have a skyrocket on T-Mobile 4g with 3-7 mbps download and 100kps upload for some reason...I flashed the tpc custom rom and custom kernel and tried each radio till the telus radio showed up 4g...its working great thus far. Im going to try the same combo on my note when cwm is released and stable. Hopefully it works

Why don't you read before posting? Look at the date of the post, it was before the AT&T Note was even released, obviously before it was found out that it does work for T-mobile.

AT&T and ROGERS GNote

Will everything that works for the at&t note work for the Rogers note? Like unlocking, rooting and custom roms?

They will most likely use the same rooting methods.
Possible the same ROMs
And it's possible they may require a different kernel.
It's really hard to say though. Your best answer is to look at previous Rogers / AT&T phone development on Samsung phones. I really hope they share the same ROMs.
They NEVER use the same ROM but it is not to say you can't interchange ROMs. Sometimes, there is some very small hardware differences as well. They have different product code as well. By all means, they are not the same phone.
I have owned several rogers phones that are also on at&t i can confirm that so far thy have been identical only major difference is one has at&t crap and one has rogers crap. As far as Roms they are usually the same.

Are the Bell and Telus versions also interchangeable with the at&t version? With regards to both development and general network use (voice, UMTS, LTE...)
Reason I'm asking is because those 2 carriers don't brand their phones unlike Rogers and at&t. The Streak and international phones have spoiled me in that way.
That i can't say forsure but my guess would be they are all the same. If anything the kernels may been to be changed depending on your network

THe Robellus ones will have 1700 AWS LTE whil the AT&T one does not include these frequencies, or so is the norm on most devices according to what i have heard
You will know when the rest of us do.

US version Galaxy S III rom development

With the US version having the same hardware, will we be able to flash the same roms on all the carriers? I know we have to flash our own kernel and modem to work on our network.
Negative. International version has exenos and the north America version has the s4 qualcomm
Sent from my SGH-I777 using xda premium
I'm only taking about the us version, they are going to release to all the major carriers at the same time.
Sent from T-Mobile's galaxy S 4g for a minute until the SIII is released in the United States
But they still got a s4 instead of exenos.

actually i don't think its gonna be that bad...as long a rom doesnt include a radio, and you inject the appropriate kernels... roms will for the most part be interchangeable between the US Variants

hopefully we can flash Tmobile ICS rom on our AT&T GNOTE for those who are using At&t Note on Tmobile networks. can't wait to find out if it is gonna work... At&t GS2 Skyrocket and Tmobile GS2 roms were interchangeable so maybe the NOTE is gonna be the same..

From what I understand, we can do it as long as we don't flash the radio and bootloaders. This is as long as they have the same hardware (except the radio of course). If they are going with a different processor, we will be able to use the ROMs but only if they are heavily modified.
As mha1021 said, it would be like porting ROMs from the Skyrocket to the GS2, but you can't flash them as-is.
Would be nice if this helps us get better 4g speeds

Sprint Galaxy S 3 (USA) vs international galaxy s 3 question

Here is my issue. I am currently in the US. I might teach ESL overseas in Korea in January. I am not sure which phone to get. Will the USA one work over in Korea? Will thew international one work in the US?
It could work but Sprint has the radios locked.
Would developers be able to get them unlocked?
Buy international set

They propably can but the intl one supports more radio frequensies and is assembled to work worldwide so I'd buy it in any case rather than us version.
Sent from my GT-I9300 using xda app-developers app
The international one works in the US flawless... just not on all carriers... it works the best on AT&T if you want to use it in the US and get 4G(HSPA+)
You can use it on T-Mobile but you will have to settle for EDGE(2G)
Sent from my GT-I9300 using Tapatalk 2
It would work on most carriers which uses the international frequencies.
Not just AT&T for US. Works with Rogers, Fido, Telus, and Bell Mobility in Canada for instance.

Just a side note, HSPA+ is not 4G. It's still 3G. LTE/WiMax is 4G.
so which companies will it work with 4g/lte? Will it not work with Sprint? Anyone know any deals for the international version?
Sprint (and Verizon) is on an old CDMA network while the majority of the world is on GSM, you know, operating with a SIM card. If you're set on travelling, it's better to get any of the GSM-variant, that way, you can just pop in any sim card from any major carriers all over the world.
I currently have a photon which has a sim card slot in it. So the Galaxy s international wont work on Sprint? Damn I want to keep my SERO plan lol. So where can I get an international verison from? Also would I have to pay full price for it?
Does the photon has an active sim card in it? I'm assuming no. I've never used a dual-mode phone before (nor am I familiar with how they operate on different networks), so I dont know the ins-and-outs on how to get it activate for a GSM carrier.
Damn, now i have a headache just trying to figure out how it works to have an intl GSM phone on a network that is predominantly CDMA whom happens to offer a dual-mode phone on their network

The SIM in the Photon is just for roaming. Sprint does not use SIM cards - even their LTE phones have them embedded rather than user-accessible.
As the Sprint Galaxy S III is not a 'global' phone - i.e. does not have both GSM/UMTS and CDMA radios - do not purchase it if you have any intention of using it outside the US. CDMA is no longer a global technology.
Confuses me a little that people spend so much on devices without checking what networks they support. Ho-hum.
