I've searched for this quite a bit, but haven't seen anything definitive.
I have an S3 from Sprint that I want to use on Page Plus. I've got it working on page plus, but not all of it.
I'd like to get rid of all the Sprint specific software to go to something either verizon or more generic, that won't
be trying to access my "sprint account" all the time, (which doesn't exist)
Is this possible?
I'm not familiar with too familiar with flashing phones myself, but i've read about them
Does PagePlus work on Verizons network then?
If it does, you should be able to flash the rom fine, the only difference between roms made for each phone are the vendor files (theres actually a project in place right now to make a rom that will work for all carrier-specific S3s)
I would strongly suggest making a backup just in case though, and the usual disclaimer: i take no responsibility for your actions, but i would be more than glad to help if something goes wrong
Also if you root, you can install a clean rom that will have all the bloat remove, that way you're not just replacing it with other bloat lol
Good luck :good:

Yes, page plus uses verizon lines. I figured that a verizon rom was a good starting point, but if a custom rom would do the same thing, I'm not opposed to that either.

Ok then, what I meant was that you could flash a custom Verizon rom with all the bloat removed, there would probably be things that you would need to change thought if you did flash it, like your APNs and such...so make a Nandroid just in case
You can try a Verizon prl also
But you might not have lte Verizon uses a sim for there 4g

True but the prl might help if he needs to connect for cell towers. But I know from other Verizon phones they need a sim for 4g services and a sprint sgs3 does not support sim card

Yeah, I don't care about LTE really, just trying to figure out if I can get a verizon rom to flash on it, or custom, that will blow away all the sprint specific stuff on this phone. it doesn't seem real happy to be a sprint phone on a verizon network.

I've had many Android devices over the years and flashed a few ROMs in my day. I haven't messed with any of that in quite a long while though.
I've recently switched from all Sprint and all HTC devices to T-Mobile's Galaxy S3. I searched and found the thread about the Team Sonic modem flasher. I tried to read as much as possible but don't think my question is answered there.
Basically.. I get no service at my house and cannot manually select the AT&T network. Everyone with AT&T (including my girlfriend who has the S3) gets service here. Can I flash an AT&T baseband on my T999? I currently have UVLJ4 and get nothing inside and 2G outside whereas all the AT&T people get 4G in my house.
Hope this hasn't been answered before.
Thanks
Sam
Pretty sure that's a no-no.
I think you could flash the modem, but you need to verify they use the exact same partition on both variants. If it flashed to the wrong partition you're likely to hard brick the phone.
An att modem is not going to get you on the att network. I seriously doubt it'd even let you even make a phone call on tmobiles network, though it could happen. I can't figure any real reason (other than pure dumb luck) that another carriers modem would be better than one coded specifically for the network you are on.
Your best bet is to try out all the available modems we already have before thinking about trying another carriers fw.
And search again, but look in the development stickies too! You may find other things you could try. For the moment the modem flasher is quite outdated. I may work on updating it this coming week for those who are still wanting it. We'll see!

Will this no-no brick my phone or will I just not be able to get any service once flashed and then flash back? I've been trying to scour XDA and the rest of the internet for answers. So far I found this info..
"The modems in the GS3 are SDR or software defined radios. Their frequency TX and RX spectrums can be modified through software. The nice thing about the MSM8960 SOC board is that the radios can be programmed to virtually any current GSM, HSPA or LTE frequency in use in the United States today"
If this is true, I should just be able to flash an AT&T baseband, correct? Then again, I read that the T999 doesn't have the LTE compatibility that every other S3 has. Is this software or hardware defined?
Its a hw limitation.
Call tmobile and let them know the situation. Since you're new to their network I doubt they'd do it but I've heard of them providing a cell repeater to put in your home. Worst they'll say is no!

We replied at the same times and I did not see this until I had already posted. Thank you. I guess I will try previous T-Mobile modems and see if one happens to be better for me. All I want is to roam but the phone won't let me choose the AT&T network even though it shows up in the network search. Customer service told me you are unable to roam as long as a T-Mobile network is available at your location.
I do not want to risk bricking so I will stay away from trying the AT&T modem as I am not familiar with this phone or any flashing that has come about in the past 2-3 years.
Here is an easy way to do. So easy a cave man can do it.
I am assuming that you know your MSL code, if you don't there are many guides on this forum for that.
I am using QPST 2.7 Build 374.
1)You must downgrade your radio to LG2 (search the forum, there are guides to do that)
2)After you downgrade, you will be able to read the phone in QPST EFS explorer.
3)Read the phone with EFS explorer
4)Move NV item 85 to a folder to your desktop. Change it to "000000" hex code 303030303030
5)Load back the NV item back to your phone and Voila, you are done.
After your change your SPC to "000000" you can upgrade your radio again.
Do not PM me, feel free to ask questions on here.

I747 has different internals then the I9300, Flashing anything for the I9300 on a US version will brick it. Unless you want a $500 paperweight, then don't do it! lol..

There are plenty floating around.. Who is your wireless carrier? (our model is the SPH-L710 for Sprint) you said you have the I747, Which is a different carrier.. So best bet would be to find the forum for that model, Go into Android Development section.. And you'll find a load of Roms!

Have to look for the ATT S3 Forums then for roms and things that would work for your phone specifically. AT&T/T-mobile uses Sim cards for the network.. Verizon and Sprint use CDMA. So if you flash anything from this thread (Sprint S3) you will brick your phone.. Just trying to ensure you don't cause any damage to render your phone nothing more then a paper weight.

Quick correction. While verizon still uses cdma in their network their LTE phones use Sim cards unlike sprint.
No
There is way more involved in changing a phone from one carrier to another. Reading/Writing SPC is only the beggining.
If you send the 16-Digit Samsung Default Password you can pretty much do anything to this specific model.
Once i get a chance i will post how to get this model Fully Flashed to Cricket/PagePlus the "manual" way. (Via CDMA Workshop, QPST, etc.)
Would that be useful to anyone here?

Also the only carriers that accept foreign MEID (CDMA Version of the IMEI)
Are MVNOs or Cricket/Pageplus/MetroPCS etc....
to my knowledge Verizon does NOT accept MEID that are not VZW

Sprint's LTE uses a SIM card as well (just like Verizon), it's just embedded where you can't see it or get to it without taking the phone apart.
Sprint and Verizon are similar in their network, both are CDMA (use the same CDMA freq, can roam off each other for voice and 3G data) but use different LTE frequencies.
Hey all, atm I use the stock rom, rooted for tmobile. (Stock rom isnt that bad for JB tbh.. to my surprise) However I just switched to ATT, waiting on my nano to micro adapter to come in so I can switch back to use it. Now as far as I read, I should have the 3g and 4g bands just fine, I just wont have LTE on ATT, correct? Next up, aside from using titanium backup to force uninstall TMOs software, was wondering, should I change out my rom too or is stock still cool to use for ATT?
That or what is everyone else doing if they took their S3 to ATT or tweaks that could help for network speed etc. That or apps that are good for ATT on it. Thanks.
Anyone? Or is there no tweaks or more ideal rom builds. Atm I mange to get 3-4 Mbps download speeds. Not sure how fast Iphone 5 gets.. Didnt test and dont feel like taking the sim out again tonight lol.
As suggested by the ATT S3 section of the forums, Ill put my post here too with more details on what I could be looking for.
Hello, Just changed from Tmobile to ATT. I already unlocked it, and am running it on 4G. Sad part is, download is only like 1-3 Mbps it seems. While my Iphone 5 can get close to 7 Mbps (Now this is just 4G band, NOT LTE)
So I am wondering if there are some tweaks I need to adjust in the build.prop or anything else. Atm I just use the stock rom thats rooted. (Since it seems nice enough for JB and honestly, I havent figured out which custom rom beats the stock rom 100% without losing any features.
Also noticed I cant install the ATT Visual voicemail as it claims device isnt compatible. (Which that I am sure I can use a build.prop edit for the model. Question is, which model and items do I need to adjust and to what value?)
Anyways, if anyone has some good advice about using the tmobile S3 on ATT and getting it tweaked to be the best it can be, or a rom that is perfect for switching between ATT and Tmobile (should I use my prepay tmo sim in it again) and provide high data speed. Would be great.
Oh also.. just so I know. Can I use the ROMs posted in this ATT section of XDA for the t999 tmo s3 or do I need to still only use roms from the tmo s3 section of xda? Thanks. =)

Not sure about the other stuff, but with regard to this, your phone is still a t999 no matter what carrier you are with. Hardware doesnt change, so I would recommend you stick around in the tmo section.
Some att ROMs may work, but not sure which, so if you DO want to use an att rom, I would suggest asking the dev if it will work for the t999.
Sorry I couldnt answer about the rest, im too noobish for all that
Sent from my SGH-T999 using xda app-developers app
Yea thats the trick, Seems its hard to even find that advice lol. I mean long as I dont use the international s3 roms. Just between Tmobiles and ATT. I dont know. I dont even know if its considered the same model and could use the same rom. Perk of using an ATT rom, may increase my network speed some along with being able to use their apps. Atm I cant use the ATT Visual voicemail since it says my phone isnt compatible. Which I know I could prob bypass that with the build.prop provided I knew which model to make my phone.
So I'm trading with my mother her T-Mobile sim for mine. She's going to take over my contact from Att and I'll take hers. Reason is her job well pay her bill but they want Att for some weird reason Lol. And i want the unlimited data with T-Mobile. So my question is once I unlock both phones, well I still be able to use my current rom? witch is avatar latest with KKO kennel. Would I just use an T-Mobile modem and radio or just stick with the Att radio/modem?

yea ROM shouldnt matter. Its all about the baseband or modem. Might want to hop over to the T mobile forums and ask them. Another thing you want to do with your AT&T Note is hack it so you can use T Mobiles AWS bands. The Chip in our phones is disabled right now but we have the hardware to use the T mobile bands.

Yea I'm going to. I seen an thread bought the aws band witch I plan on doing. I'm actually kinda glad my mother wants to switch the 3gb data is kinda killing me Lol. But I think an Att radio/modem should be just fine or i could be wrong.
It's actually very easy to enable the AWS band on the AT&T Note 2. T-Mobile LTE works out of the box, but for 3G (HSPA+), you need to flash a file from your computer. You don't have to be rooted though. It shouldn't void your warranty either or trip the flash counter: http://forum.xda-developers.com/showthread.php?t=2068041

Flashing another Note 2's radio (as in another carrier's/model's) to your AT&T Note 2 can actually damage it. Not physically, but you'll lose your IMEI for example and probably get stuck in a bootloop. Stick with AT&T modems. You have to reapply that flash from your computer any time you flash or reflash a modem though. But seeing as how most custom ROMs don't come with a modem, you won't be doing that often anyways.

Yes. Although you can change ROMs freely. This mod will stick until you flash a different modem (which is separate from a ROM), at which point you just flash it again.

Yes. Modems rarely need to be changed and are in a separate file 99% of the time. Kernels and ROMs and anything else can be changed as many times as you want.

I live in north part of Phoenix az And my mother gets 4g just bought any of the surrounding area.
First, my apologies if this subject is already covered. I couldn't find anyone with a similar situation.
I have a Sprint G2 that I rooted and it is running CMod 11. I want to switch it to Verizon. I tried taking the phone to the Verizon store and they could not activate it for Verizon. I assume the phone is unlocked however because it activated just fine for Sprint and the Sprint guy told me that's an indication of being unlocked. True? Not sure.
The Verizon guys told me that I need to hack the radio frequencies of the phone before it would work with Verizon. I don't know where the settings are for this though. I already tried the trick of deleting 'Spr' out of a certain system file and I effectively bricked the phone. That didnt work and luckily I was able to revert to the stock rom.
My question is this: Can I get the phone to work with Verizon simply by flashing Verizon CMod to it? Or is it easy to find the settings for the radio frequencies that I need to change? Do I get any data once all is said and done? I don't look forward to unrooting and restoring the stock ROM JUST to hear Sprint say "Oh well we don't want to unlock it for you."

The G2 is only compatible with Verizon's 3G network. I doubt our radios work on the Verizon variant for LTE. Also, the IMEI would need to be whitelisted on Verizon's database. There's no other way around it. Better off selling the LS980 and buying a VS980 for Verizon.

1) no because the IMEI isn't in verizon's database / white listed
2) hardware for the radio is different then verizon's and you will be unable to get lte at all from it.
3) I would just restore to 100% stock (tot) and then sell it and then buy the Verizon version
i have inverse issue
well i bought a verizon variant, only because it was the only one with next day air delivery... I didnt do any research other than seeing that they had the same model number of 980 i figured a radio change and maybe rom change. i tried flashing a sprint rom on it it wont finish the install. do i need to get a sprint sim?
i might be interested in trading that sprint g2 for my verizon g2
