How to determine available frequency steps if scaling_available_frequencies doesn't exist?
I know its possible with cpuinfo_min_freq and cpuinfo_max_freq but how?
You'll need to get the specs for your particular chipset, most manufacturers will have that information in their documentation.

Then how system tuner and setcpu works, I can't imagine that it has info for every possible device and I've tried it on some really unpopular devices ...

I am interested in picking up this phone when it launches on Verizon, but I have not owned any Galaxy device before so I'm wondering how ROM development works. Is it carrier specific and I can only get ROMs for the device on my carrier? I see that the S3 is launching with some versions having 2gb RAM, etc, so just wondering which ROMs I can use. I see that there are a ton of different versions for the S2 so its along those lines. Thanks for your response.
In common it is not carrier, but network specific. The lte versions use another board with a dual core, weaker gpu and 2 gb ram.
For sure roms for the international version won't work there, except it is multi device and also made for the different board.

So in the case of the S3, all the LTE versions of the phone will be able to use the same ROMS? It seems this is a new problem "development fragmentation"

Not possible unless you are in a trial area where tmo are testing 1900mhz freq for 3g.
If you aren't there is no way due to hardware.
The intl version doesn't have 1700mhz.

What is up with all the Tmo questions and international gs3? just get the Tmo version.. its cheaper and it support your bands..

Everyone asks this with EVERY international Samsung phone. You would think people would learn sooner or later.

Because we want the European quadcore. Just because t-mobile thinks U.S consumers are too dumb and too poor to know the difference or afford it, does not mean all of us are.
If the hardware is capable then all you need is a software radio flash.
So far rumors are all the radio ICs are the same.

First, do you think it is some kind of conspiracy to keep you from having a powerful phone? THE SOC DOES NOT SUPPORT IT.
Second, if you think four cores is automatically better than two cores, I suggest you do some research.
You also have no idea what a radio is. There is a software radio, and there is a physical chip. The physical chip in the international S3 DOES NOT SUPPORT THE TMOBILE AWS BANDS, and it never will.
They also cost the same so I have no idea where price comes into this.

Just order the sim card of Straight Talk website and youll be fine...I get H+ and love my speeds...but drop the contract unless you got LTE but H+ is perfect for me and only at 45 montly....Love it..

If you do go this route, be wary that Straight Talk offers both AT&T and T-Mobile sim cards. If you get a T-Mobile one you will NOT get HSPA+

That is an uncalled for response. Based on my early reading the international version is using a chip capable of oscillating at the higher frequencies. I was also toold it is the exact same radio IC used in the t-mobile version, just like the skyrocket can be made to work on t-mobile after painfull modification.
For you to automatically assume and publicly state that my knowledge regarding a technology is limited is foul and absurd.
If i was incorrect on the IC specs then by all means feel free to correct me, but please site your source of information and be polite and professional.
Further, isn't the four core version using the same processor class / architecture?
Sent from my SGH-T989 using Tapatalk 2
The dualcore uses a Qualcomm-sourced ARM-A15 while the quadcore uses a Samsung-developed ARM-A9, both with heavy modifications to the standard platform.
So there are actually differences in performance in regard to certain tasks but since games, flash and other ressource-hogs usually only use up to 2 cores there is no real disadvantage in everyday usage even if synthetic benchmarks make you believe otherwise.
Usually -as is and was also true for desktop computers, laptops and servers- it's the storage, RAM, and bandwith that are the bottlenecks.
And at least in terms of Ram the Us-Version got an advantage.
I'm not sure about the SoC but wasn't the whole point of Samsung not integrating the radio in the SoC that they could easily pair it with different radio chips? All it would've taken in that case is a different baseband processor, amplifier and antenna - not a whole new CPU arch which happens to include LTE

Oh so you need sources from me but you don't have to cite your own? I may have been harsh but there was a thread on the same page as this one and the people asking in this thread hadn't even bothered to look for information, but to call you out was wrong.
In any case, the four core version uses a cortex A9 compared to the two core version using a cortex A15. The architecture is ARM, yes but when it comes to the SoC as a whole the Exynos SoC has never supported AWS. I'm not saying it is not possible for it to reach the higher frequencies as you said, but it is not a conspiracy by any means. Both are great SoCs, but the fact is the exynos does not and will not support AWS.
Also the Skyrocket modifications are not painful, as far as I know just like the AT&T Note you just flash a radio to enable the bands. The problem is the exynos SoC does not have the bands necessary.

I never made an authoritative statement, simply gave my reason for desiring the quad core based on my beliefs. You are correct I should have been more clear, but let us both make peace as we are both members of an educated class.
Thank you for that information, so letme all you guys, what is the superior platform in your opinions.
And do you know if the at&t version will work on t-mobile with a radio flash as it seems to be cheaper.

Hi,
Which frequencies does the S3 support on the 5GHz wireless band?
http://en.wikipedia.org/wiki/List_of_WLAN_channels#5.C2.A0GHz_.28802.11a.2Fh.2Fj.2Fn.29.5B14.5D
I have looked but couldn't find anything on the web.
Any assistance would be appreciated. Thank you.
Anybody? I could really use a reference to some document that has this mentioned...

Well, 5GHz is a frequency, so I would guess that it supports 5GHz?
Thank you all guys for your answers... I was looking for a more technical answer TBH
No, 5GHz is a frequency range... obviously no body cared to look at my link in the first port...
Nevermind I thought this forum has technical experts from all fields related to mobile.

I posted an image of what channels can be used on an international s3 at 5ghz. Look at your link and match the channels to frequencies not hard to do.

So once I planned to root and got into XDA, I always read "INTERNATIONAL ONLY, AT&T ONLY ..ETC ONLY"
Why? Why does the recovery differ from INT and AT&T and sprint and all those other variables? Why can't we boot a rom for the INT to other variants and vice versa?
I know that it belongs to CID (i think?) But why? How is that CID set? And what's different between each CID and the other?
Thanks you guys

The international and AT&T version, have different radio hardware. The international one uses the Tegra 3 inbuilt radio hardware where as the AT&T version uses a quallcomm 4G radio chip. Because of the different hardware the devices require a different kernel, thats also why they need different recoveries, because a recovery is basically built from the kernel.

Hey guys, making a transition from the htc sensation forums to here and was amazed to see four different sections dedicated to the S4. I just want to know which is the best place to get a rom for my S 19506 model (the newest one with Cat 4). I'm with Vodafone Au and don't really fall into any of the other categories such as Sprint, T-mob, Verizon and At&t.
Thanks

There's actually 5 altogether, one is simply Samsung Galaxy S4 for all of the international (non US) models. you should use that one.

The reason why I didn't go for that is because I don't have an Exynos Octa Core. I have the Snapdragon 800 2.3 GHz. Would this make a difference?
