Not sure why it's so hard on the S3 because the S4/Note 2 is very simple. My friend have a S4 that we tried putting a t-mobile sim and it work without even rooting it, just added APN settings and a tutorial how to enable HSPA via dialing code, I have a Note 2 and mine worked right of the bat no rooting or anything, I just added APN settings and it worked (both from Verizon of course).
[Verizon Samsung Galaxy S III] mybook4:
Not sure why i have to say this, but the S3 and the S4 are two different phones.

This is dead
[Verizon Samsung Galaxy S III] E:V:A:
The reason this thread is dead is because it is way outdated and very hard to get an overview of everything that has been tried/successful. In addition the phone is getting slightly dated and the best people move on.

However, I am still convinced that this is entirely possible...

If OP could run through all the pages :P and summarize our findings on the first 3 posts, perhaps it would help others to move this forward.

Please, correct me, if I recall wrong. But was it not so that some changes was actually successful, but they would not "stick"? If that was indeed the case, it is all about not understanding the underlying file structure. I.e. What gets modified when and where.
[Verizon Samsung Galaxy S III] preusstang:
Unfortunately :(

I flashed to page plus but it would be oh-so-much sweeter if I could switch to net10 or straight talk..

---------- Post added at 06:24 PM ---------- Previous post was at 06:22 PM ----------

Sorry for double post but yes, there was an NV item or two that made it work but the changes would not survive a reboot. Is there no way to change NV items without a PC? If it could be done in an init script that would be lovely..
[Verizon Samsung Galaxy S III] My1gdsm:
I think it's 100% possible. I need to dig around. But I think that I got the phone to switch to the 1900 band. But it would imediatly switch to the GPRS/EDGE. I have a Screenshot of it that someone else may be able to make more of than I. Not a lot of free time to play with this at all lately with work an all.

Totally agree E:V:A

The last few pages of this thread as so in between started to get somewhere it would be nice if the OP or someone with a post on the First page could update their posts to reflect some of what has been done or needs to be.

I really hate to say it But I may just sell this phone in the near future if someone with the desire to work on this more doesn't step up. -_-
[Verizon Samsung Galaxy S III] E:V:A:
What do you mean "without PC"?

Again, AFAICR, I proposed to use your modem connection and AT commands to set NV items, band usage etc etc... It is possible that modem can use its internal magic to make these changes persistent, unless crippled in firmware. This could be done by having your init script sending some stuff to the modem. [Problem has been accessing modem device from within the phone itself and not via external USB/PC connection.] However, this is not trivial and I don't know how to do it for this phone. (Searching other old threads, seem that some people have been successful.)

DO have a good look in the modem firmware. It is very likely that Verizon has implemented OEM AT command(s) for setting bands. Could someone link to the modem firmware used in this phone? Then I could have a brief look, which means someone else should do a closer look...

Having working settings to stick should be a trivial problem to solve.

Another suggestion is to temporary close this thread and start a new development one that is maintained by an active members. Continuously updating OP. However, I will not work on this, but will try to help when I can.
[Verizon Samsung Galaxy S III] Rich3077:
Okay I am going to port a T-Mobile Rom over to my S3 and I need to know if it is safe to flash the T-Mobile modem along with the Rom? I have so far flashed a T-Mobile Rom already but had a few bugs to work out. I like getting the whole feel of T-Mobile including the WiFi calling feature and voicemail menu working as it should.

Also what firmware would I need to flash to get the same service menu options as the T-Mobile version? They have a way to unlock via the service menu that is disabled in our phones. Probably wont work but if I don't try it myself I wont be satisfied.

Thanks

Dont know if the bounty is still up, but i'l put some $5 from my side!
[Verizon Samsung Galaxy S III] LLStarks:
Just a warning...

DIAG and AT commands are a fast way to brick your phone if you don't know what you are doing. Many of the tools involved in this kind of research were designed with CDMA feature phones in mind. QPST is pretty safe since dangerous features are isolated, but one wrong click in QXDM or RevSkills and you're done.

Btw EVA, are AT calls doable through DIAG, ADB, whatever or do you need a crazy voltage-at-boot setup to enter the mode?
[Verizon Samsung Galaxy S III] Rich3077:
Just confirmed that my old galaxy 2 jig works with this phone. I will get back you you about this.
[Verizon Samsung Galaxy S III] Rich3077:
Just hard bricked my phone trying to install a T-Mobile modem. The jig isnt helping because the phone wont power up in any way, shape or form.

I really didn't expect a hard brick, live and learn.
[Verizon Samsung Galaxy S III] E:V:A:
Any time you connect an Qualcomm based phone to USB, the DIAG interface should eventually be available. The QC devices have a few modes of operation; normal, download (emergency flashing), diagnostic and factory mode, and perhaps some others. The AT interface is almost always be available. AT interface talks serial with ascii. DIAG interface talks raw binary commands sent with checksums. (RevSkills, QXDM, etc.)

You probably have to use AT command to set your device ports, and mode into DLOAD, DIAG or FTM.

Why would you do such a stupid thing!? Did anyone tell you to flash T-mobile onto a Verizon phone!? I don't think so. This thread is not for you. Take your phone to prof service shop and I'm sure they can fix it for you.
[Verizon Samsung Galaxy S III] Rich3077:
Harsh words for someone who was only trying to help out. Since you don't want me in your thread I will stay out. Cheers.
[Verizon Samsung Galaxy S III] E:V:A:
You wanting to help is appreciated, but not currently helpful. This is obviously not a noob thread since we have not made much progress in 44 pages of highly technical mumbo jumbo! So don't take it personal!

E:V:A

I've been following this thread since April, hoping a fix comes along. My husband is about to throw his i535 out the window because he can only connect to the EVDO network. Finally joined XDA although I've been a reader for years, you guys are the best. I wish I had the time and knowledge to help.

I'm in for $40- it's either we find a fix for everyone to do this, or I pay $40 to flash this device to pageplus or Verizon prepaid. I would rather find a fix for all. I am also willing to test and confirm when a fix is possibly found.

And don't forget to read all the comments as well.

And HERE is the National SID Assignment and Conflicts database.

Now I suggest someone rips out their PRL form one working and one not working phone, and compare. [AFAICR nobody has done that yet. Just NV items...]

And HERE's a PRL relevant XDA thread for Sprint users.

(Non-working phone?)

When I get a free moment, I'll dump my PRL.

Btw, I really only use my TouchWiz backup for this thread since diag mode doesn't work with CM10.1 or CM10.2 yet.
[Verizon Samsung Galaxy S III] LLStarks:
I'm at an absolute loss as to which QPST versions work with Service Programming.

366 and above fail to install and 323 is the only version that has any success even reaching the Service Programming screen before failing. 264 allows the menu to open and reading if I set the device as an older SURF type but PRL backup seems incorrect.

CDMA Workshop and QPST produce only 1KB PRL files.

How the hell am I supposed to pull the PRL off the phone if no working tool exists?
[Verizon Samsung Galaxy S III] My1gdsm:
IIRC 378 works... I'd take a look an see... But I'm not on a Touchwiz Rom at the Moment.

Though last Time I was I'm PRETTY sure I was able to make a NV Item change and have it stick. I need to get the phone back on a TW rom or able to connect on this.

Anyone else,

I was wondering...

I know a few people at this point have tried to flash a few different modems to the phone. Though not completely successfully obviously. I have only managed to get the Not approved Software message screen and Had to Start from scratch again. But, I've noticed a few people say they just had No Service But the Phone booted up. I curious what modems they were and exactly how they flashed them???
[Verizon Samsung Galaxy S III] E:V:A:
If you Google properly, you should be able to find QPST 2.7.402...

but .378 should also work.
[Verizon Samsung Galaxy S III] LLStarks:
I've used both builds.

[Verizon Samsung Galaxy S III] nicklefloss:
bounty time

I love this thread first of all!

I had an Idea, why not use the app called ROAM CONTROL. I used this app while I was with sprint and used Verizon's towers, I even got Verizon's 4g lte access on my sprint sgs3, I know it worked because South Carolina doesn't have sprint's 4g lte. Hey someone please try it I have the app. I already paid for it and I have the purchase code. Again roam control! I think it would work.
[Verizon Samsung Galaxy S III] LLStarks:
This is not a solution and your post reads like spam.

The LTE part sounds impossible since you need a SIM card to access Verizon's LTE and the necessary bands are not supported on the phone.
[Verizon Samsung Galaxy S III] nicklefloss:
Only reason I said it is cause I was able to access Verizon lte from a sprint phone... and again when we normally roam on Verizon from a sprint phone we get the lowest bandwith. All I can say is try it ill get your my code... I really think if the phone is set to global (gsm) then it might work and from there may be it would give someone on here something to work with...
[Verizon Samsung Galaxy S III] aDigitalPhantom:
The reason a Sprint phone can in theory access Verizon towers, is the fact that both Sprint and Verizon use CDMA. AT&T, and T-mobile use GSM, that is where the bulk of the problems are from.
[Verizon Samsung Galaxy S III] mybook4:
This is true for 1xRTT / EVDO, however the poster said he had 4g, i.e. LTE. Sprint has access to LTE bands 25, 26, and 41. Verizon has access to LTE bands 13, and 4.

Unless the L710 (d2spr) is capable of accessing a band 13 or 4 network, and Verizon/Sprint have some sort of roaming agreement for LTE, I don't see how it is possible to get Verizon LTE service on an L710.
[Verizon Samsung Galaxy S III] aDigitalPhantom:
I will admit that I did not know that.
[Verizon Samsung Galaxy S III] nicklefloss:
Well remember the reason why I wanted sone to try it is because when you put the phone in global mode the phone is a gsm phone at that point. But if you say it won't thanks for even listening and teaching me.
[Verizon Samsung Galaxy S III] LLStarks:
Global Mode doesn't enable HSPA. Just voice and EDGE.

Our problem resides deep within the NV and firmware levels.
[Verizon Samsung Galaxy S III] ddrum2000:
On TMO and AT&T this is true but carriers in other countries it does enable HSPA
[Verizon Samsung Galaxy S III] nicklefloss:
Can you explain this a little more?
[Verizon Samsung Galaxy S III] ddrum2000:
So the global mode on VZW version of the GS3 enables the unlocked quad band gsm radio as well as HSPA available on 2100 mhz. As long as you as running a jelly bean rom with the appropriate updated modem it should work with no problem. It worked for me with no problem in italy and Hong Kong with a prepaid sim.
[Verizon Samsung Galaxy S III] kalanir:
Anyone?

So whats the status on this? I got a bad esn one here and dont got nothing to do with it so fire away
[Verizon Samsung Galaxy S III] My1gdsm:
I'm no Dev by any means... But am going to try a few things in my scope and revisit some of what may have not been directly answered. Maybe if I get sometime get a check list up that covers what has and hasn't been done that was asked in the first post. Though my free time is limited...

That said pretty much a lot has been covered and not much progress as far as getting changes to stick and this working has happen... Lot a good info in here. I think I missed a good 10 pages going from 30 to 40 the first time around :(

Anyway,

If anyone has any Idea's I'm all ears I just picked up a I-747 and still have the I-535, I'd be more than happy to do about anything need be to get this working and having both in hand I'm sure that's a bit more helpful than anything so far.

But If someone doesn't any Ideas to push things further the I-535 is going to be sold in the few weeks more than likely. :eek:
[Verizon Samsung Galaxy S III] treyjazz:
Sorry if this has been mentioned before. Has anyone working on this tried going with a different approach and tried tricking the phone into thinking it was in a different country to unlock all the bands for 3G use?
[Verizon Samsung Galaxy S III] djteotancolis:
Tricking wont help since the Bands are locked altogether. You get 3G in europe and asia cause they use the 2100 Band which is 3G unlocked on this phone
[Verizon Samsung Galaxy S III] My1gdsm:
I tried what I could to set the phone up as it was on Vivo, Telemig and Claro as they are Brazilian GSM providers But didn't get very far and still only had edge.

This is probably the closest I got to anything threw all this below... I managed to get screenshot it Shows EDGE in the top of the screen But Right when it connected the display would switch to EDGE(2) from showing PCS1900 Not sure if this phone would Show WCDMA if it can connect.

I just think Without the means to Flash different firmware with a true bootloader unlock this is in the end is going to be difficult lol

I'm no expert But I think this may be only only way and why there is not a lot of activity anymore unless someone is holding out LOL :confused:
[Verizon Samsung Galaxy S III] ddrum2000:
If I remember correctly, the phone is only capable of edge on the 1900 mhz band
[Verizon Samsung Galaxy S III] My1gdsm:
Did you look at the screenshot? It momentarily connected to PCS1900 Before handing off to Edge(2) :confused:
[Verizon Samsung Galaxy S III] ddrum2000:
PCS does not equal WCDMA, it only refers to the 1900 mhz band.
[Verizon Samsung Galaxy S III] My1gdsm:
Missed my point... Also FYI there are markets where PCS1900 has been converted over to HSDPA... IMSMR

Oh well,

I sold the phone for more than I paid for it quite a while back and Now have no problem getting LTE or HSPAP 15 Now :laugh:
[Verizon Samsung Galaxy S III] ddrum2000:
Agreed there are 1900 mhz umts/HSPA markets but the SCH-I535 does not have a 3g radio on the frequency, only 2100 mhz.
[Verizon Samsung Galaxy S III] My1gdsm:
:eek: Guess the last 47 pages are pointless than... :rolleyes:

Back to on point

If anyone in the future picks up back on this and needs any info from a I-747 let me know, I would still be glad to be of any help if I can. :good:
[Verizon Samsung Galaxy S III] kalanir:
isn't the 1900PCS a CDMA band?? as in the 3G cdma??
[Verizon Samsung Galaxy S III] My1gdsm:
Iirc

The Sprint "pcs" that people might remember originally was actually a GSM service. A Cdma network is just what sprint is now...
[Verizon Samsung Galaxy S III] meskes:
Your points are moot. There's absolutely no way you could access Verizon LTE with a sprint phone. For all intents and purposes, LTE IS GSM. They use the same TDMA air interface, which is why you need to have a sim in the phone to operate.

Yes, this phone is quite capable of bouncing off of both CDMA and LTE; that's because it's got two separate chipsets to make this possible.

If, and this is a huge if, your phone is receiving a "4G" signal, it's because your phone is some how still bouncing off of one of Sprint's Wimax sticks.

As far as I know, sprint and Clear Wire has decommissioned *all* of their Wimax infrastructure and are supposedly in the process of rebuilding it as LTE.

It's been a while since I worked for Sprint, and that's a nightmare I never want to revisit. (Verizon is actually a much better company to work for, as I've worked for them, as well) but as Wimax and LTE are two mutually incompatible technologies, there's absolutely no way possible to connect to Verizon's LTE network with your device unless you meet two conditions.

The first is that your handset *has* to have the LTE hardware, and the second is that both Sprint and Verizon have to have a roaming agreement in place for the LTE network; their roaming agreement for the CDMA network does not automatically apply to the new infrastructure.

I've been following this thread for only a short time, but I'm beginning to wonder if opening the PCS for this device is even possible.

Sure the hardware may very well be the same as AT&T's but if the modem hooks aren't even there, it's going to be a long shot, even if the modem was successfully decompiled all they back to it's initial language, be it assembly, C, or what have you, if you don't know where to put in the code to hook in and open the band, it can't be done. I mean, we don't even have the data sheet for the chip so it's not like we can just look at it, find the registers and code accordingly. And probing each individual register, just to figure this out... For *one* band? To me, while it would be great, just seems like a huge waste of time.

I'm not trying to be overly pessimistic here, but I'm just quickly coming to the conclusion that it's probably not going to be worth the time nor effort to accomplish this.

I'm sorry if I'm out of line, and I'm more than willing to be told to STFU, but unless we get some good data sheets or there's a miracle of some sort, I don't see this goal coming to fruition any time soon. If it does, I'll gladly eat crow, though.

[Verizon Samsung Galaxy S III] nicklefloss:
Ok first off I'm not dumb, I have been messing with phones for a while to know what is and isn't, the sprint Samsung galaxy s3 is an Lte device... But it doesn't have a a sim card slot... You may not have worked at sprint for awhile but as of January this year sprint launched its Lte.

The reason why I have hoped for roaming to work with, is because of the old htc touch pro 2 (remember that) I had it for sprint and tweaked it to use art's network. Anyways read on the sprint gs3 use'll see that it is Lte and can roam on Verizon's Lte ...
[Verizon Samsung Galaxy S III] mybook4:
To learn more about how LTE, roaming on LTE, LTE bands, the air interface, etc, I recommend reading the book here http://www.amazon.com/EPC-Packet-Networks-Second-Edition/dp/012394595X

I'm about halfway through it and it's taught me quite a bit about LTE and interoperability with WCDMA and CDMA/EV-DO networks.

This effort was a lot of fun for those digging through the device, learning and looking for answers (myself included). It also will help others in the future who are interested in doing the same thing for other devices. More info could be found, and the i535 might potentially be made to work with WCDMA/UMTS/HSPA on the PCS spectrum (1900Mhz), HOWEVER....

It takes time and need. Need is limited as there have always been other options (e.g. sell the i535 and use the money to buy a T999 TMo GS3 or a Nexus). Time is hard to come by as we are all busy. Additionally, people don't hold on to phones forever.

This effort is probably not going to end with the goal being accomplished, but that doesn't mean it was unsuccessful. Many have and will learn a lot. Take it for what it is. If you really need an PCS or AWS capable HSPA handset, don't wait for this to happen.

Gentleman, and Ladies,

I have been digging into this issue for several weeks now and have seen quite a few concepts, unfortunately none have come to fruition.. YET.

E:V:A - Why do you feel so adamantly about the PRL? I was doing a lot of fussing with the PRL file trying to get Virgin Mobile properly flashed on this phone but it never would enable 3g/4g capabilities even when matched with profile data and ha/aaa keys. I also didn't notice the phone doing anything differently (nam data, profile data, nv items) through that process. I am just curious why you think this PRL is preventing the phone from grabbing a WCDMA/HSPA/PCS 1900mHz signal?

I completely agree with the NV item 1877 write, although every method I have tried to get it to stick does in fact revert back to original.

This includes:

Write via DFS v13.9.29.0, reboot.

Write via CDMA WS v2.7, reboot. (Download 1877 nv, modify to appropriate values, save, restore via write button.)

Upon more research into the NV item differences between the SCH-I535,747,and T999 I am actually thinking items 722 and 723 are of more value. I am referring to this method that MOTO users are claiming works, http://xdaforums.com/showthread.php?t=2166542

In essence they are only rewriting the value that causes the phone to automatically block the 310 MCC and 260 MNC codes. The reason this is of interest is: Is our radio simply not activating the 1900 mHz spectrum because of this country code? Or is it not activating due to not knowing it's there (i.e. nv 1877 flag)? Or is this a combination of both?

The crappy part of this is: I can NOT get RF NV Manager from QPST to read items 722 and 723 for what I feel is the only way to get the re-write to stick. DFS won't write, CDMAWS won't write. I am comparing the data from raw NV dumps and also cross referencing Autoprime's list http://xdaforums.com/showthread.php?t=1954029 and QXDM NV Browser entries.

Here is also a link to the original poster of these nv item pulls from the i747, T999: http://forum.gsmhosting.com/vbb/f286/nv-items-t999-i747-i317-t889-1647823/

Let's get this rocking again! It must be possible! I think the best way to tackle this would be to get a Google Hangout, Skype, IRC, or phone conference down and we can all work at this together! I BELIEVE COLLABORATION IS KEY!

P.S. does anyone have a known valid HSPA+ PRL for either the T-Mobile or AT&T Variant of Galaxy S 3? Wanting to test some more but can't find reliable files.

- OORAH - Semper Fidelis - Tomfoolery in all of it's glory.
