Hi everyone,
I have a SCH-R530C with 4.1.2. I want to unlock it to BRING it to T-Mobile. The phone was originally on Cricket. When I use the "*#197328640# etc, etc..." method.. it does not bring up any options under networks. Is there any solution to this?
Thank you!
Downgrade your baseband.
Samsung patched this in 4.1.2

And this goes without saying usually but use a baseband for SCH-530C, NOT a T-Mobile baseband or you might brick.
Ya that makes sense. With the downgrade does it allow me do the method mentioned above. Also, I don't mean to ask for too much.. But can someone point me in the right direction to find it? This model seems rare.
I'm pretty sure you should be in the Verizon forum, or maybe Sprints.

It would be Verizon. The model number is exactly the same between the two just Cricket has a C - hard to believe they didn't launch with a 4.1.1 ROM though... Let me do a quick search.

I did the research and MetroPCS uses the same version as cricket. You might try these Odin images from cricket users or post there to see if someone has the original ICS radio or if they know another workaround.

That's why I mentioned Verizon first. But it seems it may not be so simple any more.
The recently released Straight Talk SCH-S960 belongs in the Sprint forums. I spent a couple of days helping a couple of people find and verify this.
So it probably does belong in the Verizon area, but w/o looking I can't say for sure.
It seems these latest models are all now shipping with 4.1.2. (T999L, SCH-S960, SCH-R530....)

It makes sense that the St version is Sprint - all of their Android phones are Sprint. They don't want to pay what At&t and Verizon want for smartphones. Sprint gives em cheap at wholesale.
The R530 seems to be the same for Verizon, MetroPCS, and Us Cellular. From research, the JB update was a 4.1.2 radio - also some are saying that the ICS radio might not even work with that workaround. The MetroPCS version appears to be the exact same as the Cricket version so it should be safe to flash. Emphasis on should.

Right, and that's where the confusion came from. ST was expected to be with Sprint forums, but the SCH, made people think it was Verizon (and a few thought T-Mobile since ST uses their towers in some places apparently). I was just trying to point out that we can't always go by the prefix in the model number anymore. Why they did this.....I wish I knew!
So when they were updated to JB are you saying it skipped 4.1.1? Sorry if I'm getting myself confused or misunderstanding you.
And I'd have to look, but I thought the unlock worked for ics too. But I could be wrong.
Also POSSIBLE, but not recommended, is flashing another models radio. Most of the S3's have the same partition layout. I know several that have flashed other radios w/o bricking. It didn't work, but it didn't hurt anything either. Could it be possible to do this just to unlock, then go back to stock radio?
For example, AT&T users and T-Mobile users have tried each other's radios. All T999 variants can safely flash each other's radios too. They may not work at all, or only partially, but they were able to simply reflash their correct ones. This makes me think that as a last resort it could be attempted. I do not and will not recommend it since I know next to nothing about the 530, but figured I'd throw it out there in case anyone wants to look into it.

The Us Cellular version actually supports more bands than the Cricket version...
Cricket: Frequencies and Data Type: LTE Dual-band: Band 2 (1900MHz), Band 4 (AWS); CDMA 1x/EVDO Rev A, Tri-band: 800/AWS/1900MHz*
Us Cellular: Frequencies and Data Type: LTE Quad-band : Band 2 (1900MHz), Band 4 (AWS), Band 5 (850MHz), Band 12 (700MHz) CDMA 1x/EVDO Rev A, Tri-band : 800/AWS/1900MHz*

I wish one day they will just sale you one hardware with all carriers bands enable and none carrier branded. LTE phones now days uses a sim card to get data and works with calls too. Make it like international here in the us. Buy a phone and your free to use it on any carrier lmao. One hardware for all. No more difference between the international and us. Now newer devices are like that. Like the htc one and the s4 but we still need carrier approval for updates. Also I dont see why carriers have to put bloatware on phones when you can get them on the play store.

The biggest issue is all the different frequencies in use... And its going to get worse with the 600 spectrum sale. There are an insane amount of bands and technologies in use.
And then there are companies like Verizon that are anti-consumer... That's not going anywhere.
Correct me if I'm wrong, but I thought the S4 was the same as the S3 regarding international vs US. I heard its more compatible between US versions, but not with international since it once again gets the best processor (Exynos octo core) while we get the Qualcomm quad core one. This time we don't even get more memory. Still 2GB.
The international also uses a different graphics processor. Not sure if it's better, but it is different.

The US and most of the world are all on Qualcomm chips in the S4. Korea got the Exynos as did most of Africa and Asia in general while the US, Canada, and Europe all got Qualcomm.
That new S4 would be perfect for T-Mobile once they have lit up full LTE since they're deploying LTE-Advanced out the gate.

ok, I wasn't sure about that, thanks for clarifying it. It's no wonder sales aren't meeting expectations. It's basically the international S3 with US memory! (I know there's more to it, but when you really simplify it....)
I was thinking the same on the new S4. Don't see any indication one way or another if T-Mobile will actually get it though. And oh how I hope we do!
I can potentially see many unhappy original S4 buyers soon! (Look how upset some are over the T999L!)
I'll leave it there on my end, seeing as we are now just a little bit off topic!

Yeah like I said before.. The US GS4 being able to flash roms from the International is a huge + for me.
How about that iPhone? I always heard that it supports all global bands? If Samsung didnt had several different hardware between the phones like for international and us. It would be easier for them to push updates. And be cheaper for them too.. Not having to work on several hardware difference for an update. Maybe they got that idea and started to make the phones with same hardware like the S4.. I was waiting for fathers day to see if tmobile would have an offer for the s4 and they didnt

T-Mobile's "offer" for the iPhone 5 wasn't even really an offer anyway - its all based on their trade in program now. But they did slash 50 bucks off the S4 until 7/30 when it goes back to 149 down and 20 a month.
As for the iPhone being global, didn't they have some super custom crazy modem made for that though?

Since the AT&T GSIII) and T-mobile GSIII) are basically the same phone I wounder if the AT&T version will work on T-mobile 3G/4G. Similar to the way the AT&T Galaxy Note works on T-mobile 3G/4G. I was gone probably by the phone out right to use on T-mobile. AT&T has it for 550.00 where as T-mobile has it for 630.00.
I don't think so because att phone doesn't support mobile's aws band but idk if you could flash a modem. I did that on my note but the speeds were horrible. But yea t-mobile is expensive I just paid 680$ for my s3 today at my retail store..

I don't know, i'm wondering the same thing. the phones are identical. I think it's a very high possibility that there will be rom/radio/ kernal combinations in the future that will cater to t mobile radios that we will easily be able to flash. Just unlocked mine, I think i'm gonna have faith in US GSIII development, identical hardware and eventual full cross compatibility.
As far as I know, the Att has an lte modem and the tmo doesn't. I read that even when tmo launches LTE it won't work with the gs3. But, the tmo has att hspa+ support 1700mhz and should work with att 3g no problem.

The modem for lte or hspa+ is built into the msm8960. In theory they should be interchangeable
Would be interesting experiment for someone with rooted phone to try loading the alternative kernel/baseband then applicable sim.

What I don't get is why t-mobile would use a different chipset if the 747's msm8960 was compatible with 1700 aws. Especially since t-mobile is spending billions to refarm right now to make all gsm devices compatible with their network. It just doesn't make sense. Until there's confirmation, there are reasons to have doubts.

He spoke about trying to flash the t-mobile s3 radio in another thread earlier with no results. Returned his and ordered the t-mobile variant. I ordered a skyrocket myself. So far it doesn't look good. But of course with radios nothing is concrete. All we can do is flash their files and hope something sticks.

Has anyone tried injecting the modem.bin of T999 to the i747M CWM flash ready file and has their phone network unlocked with T-Moblie/Mobilicity/Wind sim?
There are at least two "versions" of the MSM8960, one with the LTE support, one without. The TMO version has the MSM8260A modem, which can be verified with getprop from the terminal. In essence, the TMO version does have the newer S4 (Krait) CPU, but it does lack the LTE hardware. So, no, the phones are not identical. The TMO version does support AT&T HSPA frequencies though, but the ATT version does not (at least in the default configuration) support TMO HSPA frequencies. Whether that can be changed or not, I don't know.
From "getprop" in terminal:
ro.board.platform - msm8960
ril.modem.board - msm8260a
What does the AT&T version say?
When Amazon first posted the AT&T version on their site I read a review about it saying it would work on T-Mobiles network for voice but not data.

What they undoubtedly meant was that you would only get plain old GSM (EDGE, GPRS, etc.) with the AT&T version on T-Mobile, due to the lack of proper frequency support for T-Mobile's network. Still voice and data, just slow as hell by today's standards. However, the T-Mobile version fully supports AT&T frequencies for HSPA (no LTE though).
This is not a rant nor a rave post, it's all about one's opinion regarding the difference between the International version S3 and the T-mobile S3.
I have had my S3 T999 UNLOCKED version for a while now, it's a 16gig model and after Flashing so many ROM's and whatnot, I am seriously considering getting the International version.
My decision is NOT based on the HARDWARE difference between the 2, it's based on the SOFTWARE alone.
IMHO, It's totally inconceivable to expect a device like a cellphone to be a Speed demon or have the Fastest and Latest super this or super that. I don't think anyone BOUGHT their device for that reason alone so what did we buy it for in the first place ?
1. Reliable Communication should be the #1 top reason for everyone.
2. Dependability should be #2, I would believe.
3. Utility as a personal entertainment device to pass the time when one is bored.
There are other reasons that I can't think of but it's safe to say that the T-mobile S3 is different in 1 regard, between the other GSM carriers, T-mobile has 1 different frequency, don't quote me but I think it's the 2100 .
Would any of you care to share your opinion if you had to go back and change your mind would you have gotten an UNLOCKED S3 International over the T-mobile's version, disregarding the hardware aspects of the 2 ?
P.S. Oh and BTW, Is there any end users and/or Developers that have both devices ?
Regarding the Software, I just would like to have the Essential apps that 1 needs, not all this other B$ that is dependent of the other bloated apps, I think everyone knows what am referring too, right ?
If Wild or Doc, reads this, maybe we can ask for a ROM that let's us install the apps we want on our devices via the Aroma installer, would be nice right pps ?
Yes, the T-Mobile version is different in that it lacks LTE and it adds the AWS (1700/2100) band. You never really said why you made a decision to change devices, just that you had made a decision. Personally, I am happy with the phone I have, but I am on T-Mobile, so the T999 that I have is an obvious choice. Are you on T-Mobile? If you are, think carefully before you get another version, since you probably won't get the data speeds you expect with any other GS3 version, at least not at this time.
I don't understand what are you trying to tell us, but if you going with international version make sure you get a career like Att the support hspa, otherwise you will be stuck on edge for tmobile, until they re framed their network
Sent from my SGH-T999 using Tapatalk 2
Only reason to NOT get Internation version is simply as stated before of the AWS band, you going to be on EDGE with the internation version no matter where in the US you go too. So what is your reason for switching anyway?? Because your post is confusing

From my reading of various posts related to this, it seems to be possible but you will lose signal for call/text/data. This is if one is using a T-Mobile SIM only due to the modem change right? Would I be able to at least use an international SIM instead and have everything working again? I am leaving the US soon after receiving the phone so I don't want to risk bricking and not be able to exchange the phone anymore..I could have the phone unlocked through T-Mobile but it seems to be a hassle and I would rather do it myself if possible. Also I'd like to be able to do this so I don't have to wait on updates via carrier.
Any help or suggestions would be much appreciated ::
Edit: old threas title is obviously a typo lol TOM=TMO and thus no one understood me lol
No do not flash a 7100 Rom on the 7105. They might be identical hardware wise but they have different firmware and you will brick your phone. If you'll be leaving the states shortly you should either wait or but the international version now and use a t-mobile sim in it.

But there's also a site called cellunlocker.net I believe you can check them out and see the price. A career branded note should work perfectly fine once its unlocked.

Just wanted to let you guys know that LTE works beautifully on an unlocked ATT SIII.
so what if we flash an att rom that takes advantage of the lte radio in the phone (if we truly have one in the tmo version)
Now i am not sure on that. Maybe you should try
Gotta be worth a shot:thumbup:

The Tmobile S3 does NOT have an LTE radio...
not sure why you are suggesting to people to flash a ATT rom on the T-999...

identical hardware... it was just an idea. nobody can get the lte radio myth straight, so idk what to believe.
Maybe a dumb question but arent radios flashable? Beings as the hardware is the same coukdnt we flash an att radio and rom and use our phones like they were an unlocked att version

Yes it can be done but i have had bad experiences with radios causing serious OS issues. If someone had an S III to test with that would be great.
If you flash a att radio on a tmobile phone, You might be dealing with a serious brick.
I'm confused as to why this is up and getting attention lol? I might just be brain farting but, the person posts about his AT&T phone, with at&t bands (LTE) that they work on LTE??? I'm confused as to why this is news? Enlighten me maybe...
April fools everybody.

April Fools with a bricked S3! Don't know if I should laugh or cry...
Think the OP was just stating that his ATT S3 is working on TMO's LTE network...
The ATT has different hardware than the TMO S3...its not the radio software thats the issue...its the lack of a LTE antennae on the T-999
I believe the latest software update that tmo rolled out took out the LTE software that was in previous builds
While I don't thing we will get lte on our phones the thought of the hardware being different is hard to swallow. One of Samsung's deal with the s3 was hardware unity. With this they have one plant, one run to manufactur phones and when a carrier need a stock of phone all that was needed was software. This idea of a different model just for tmobile is hard for me to believe.
Once again I still don't see lte comung for us, so please don't assume I am giving any hope to get it

The Tmobile S3 has the exact same hardware as all the other US carriers including the antenna and modem, Tmobile just decided to use different lte bands. They will not enable the lte on the Tmobile S3.

If this was the case, wouldn't unlocked T-999s get LTE on at&t?

If ATT S3 LTE can work on TMOB LTE network and T999 with same chip as ATT version.
sounds like TMOB trying to prevent S3 user to pull down they trial run LTE network.
and also prevent those people not in those trial site switch over other carrier.
I thought this was confirm a long time ago that the tmobile s3 doesnt support lte, As of an unlock att s3 to work on tmobile lte may be possible. if that the case It will be better off to sale or trade your tmobile s3 with an att version of it and you will have a s3 with lte
There will be a new s3 lte version of this phone at the end of this month...the current s3 is not the same as the att one so we will not have lte...

Howdy,
Quick question... on using the T-Mobile phone on other carriers. I researched around and it "appears" that the phones are all the same internally.. I believe this phone will work on ATT without issue, how about Verizon? Just use a applicable kernel, and modem??
The reason I ask is that my work has offered to cover cell phone but they only have Verizon and ATT
Any reason to pick one over the other?? I was thinking Verizon has they have better coverage where I need it but any other concerns?
Alternately I could just get a s5 I guess... any issues with the s5 and rooting/customizing besides the Knox thing?
thanks in advance!
I would go with tmobile just unlock your tmobile device.

My m919 works perfectly on At&t. The older boot loader (MDL) is the one I have. Not sure of the newer ones can still be switched. I always thought Verizon's radios and freqs were not compatible.

I might lean toward ATT... but my understanding is that all the s4 phones have the same hardware, the modem software determines what "bands" they use...
I see on the Verizon forums a few users have used their Verizon phone on Tmob.. so I would think the reverse would hold true...
ill research more (and maybe get some more feedback)..... don't have to decide today
I have the old baseband (no knox).
I think you can only use tmobile phones with other gsm carriers as long as its unlocked. I'm not to sure about gsm and CDMA. They are way to different.
