I have been rooted unlocked for a while now on T-Mobile But the phone is having issues with data, calls, and generally not stable. I have 4.0.4 firmware baseband I535VRLHE. I want to know what Firmware and baseband are available that I can get and be able to root and unlock bootloader. for T-Mobile to be more compatible with current T-mobile. I have current CWM The VRZ build I got was from XDA contributor. I already know how to use ODIN. Please point me in the right direction If I left out any Info tell me. I need help. Thanks
You should be able to find the firmware for your model at http://sammobile.com/firmwares
You're probably experiencing issues because that device was built for a very different type of network. If I'm remembering right, that belongs to a CDMA network, while T-Mobile is a GSM one. So I kinda doubt that you'll be able to get decent performance out of it while on T-Mobile.
Give the update a try, but don't expect miracles. Maybe you'll see some improvement though.

I guess to simplify my quarry. I was asking which update to firmware like 4.1.1 or up will still allow me to root and unlock boot loader I know some newer firmwares won't allow root or boot loader unlock. from what I understand.
Also I want to change the radio to a newer one. The VFLHE is way to old even for CDMA. Thanks for the reply
You'll need to ask in the Verizon forums about that type of stuff. Our bootloader isn't locked, but I think yours is. The only thing I really know for certain about the I535, is that it's different enough that I don't want to try to answer that myself. I think they've always had to do things a good bit different from the rest of the US S3 models.
You should probably use that forum for any of the help you need. And only flash/use things that are intended for your model. Don't use anything here unless it's been verified by other I535 users that it is safe.
You might also find others who are doing the same or similar stuff you want to do. If so they can probably help more than anyone.
If you have any questions about T-Mobiles networks and things like that, that can't be answered in Verizons forums, we would do our best to answer them here if needed. But I really think you'll find a lot more reliable information in your devices forum.
Hope that helps!

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.
I have a tmobile galaxy s3 and I'm currently using it on the wind network. I wanted to switch to a canadian provider named fido which uses the same network as rogers. I looked everywhere but cant find a straight answer. I wanted to know whether LTE will work on FIDO and if i have to do some kind of mod or would it just work from the start.
Here we go again lol

the point is YOU NEED TO SEARCH there are a million threads about this in the "General" section of the T-Mobile, Wind, Mobilicity, Videotron Samsung Galaxy S III...
The short answer is no. The T-Mo version doesnt have the proper chip to support LTE. And as stated by DocHoliday, the T-Mobile Galaxy S III was never tested with the FCC for LTE compatibility.
You would know this if you searched......
Short answer is no, long answer is maybe. A Google search would have found other threads on the subject

I did search but i didn't get complete answers. Some were no, some yes, and some maybe. I wanted to make sure before i spend money switching to a more expensive plan then finding out it doesn't work. Im still confused if it will work, because some people are claiming Tmobile representatives and Samsung have said it is LTE capable.
No, it won't work. If the hardware is there it is not enabled, and would probably take some serious dev work to enable it, which I don't think is a priority for any of our devs at the moment

I was hoping otherwise. I just got off the phone with Fido and they told me it will work, are they just bull****ting? Also I was reading in a post i wont have LTE but i will have close to LTE speeds, is there any truth in that?

If you did the research, you know as much as anyone else does. Nobody is magically going to come out of somewhere and give you the answer. If this was a simple answer, it would have been answered and verified. Anyone out there saying "it might work" or "it should work" or "it could work" is just going off of technical documents and little else. Yes it could, but it could also be permanently and irreversibly disabled via software, or other hardware means.

Short answer, no. If you want to base your decision on someone working customer support at Fido, then by all means, get the phone and hope away that you'll get LTE
I would really look to base your decision on what you know and what works today. The phone is HSPA+ 42 compatible, not sure of what the Fido network supports. Today this is often times very competitive with even the latest LTE networks, and is more than enough for any smartphone today.
Good grief.
Sir, please use the Search function, but it seems you may have gotten your answer. Thank You & Thread Closed.
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.
Hello all,
I have an international version Note II (GT-N7100). I am on T-Mobile in an area where most of the towers now use the 1900mHz band. I'm wandering if I can flash a T-Mobile branded ROM to get the use of Wifi Calling, which I've cherished the ability to have (sometimes with hacked apks and libs), on previous phones. Would flashing one of these ROMs work well with my version of the phone? Or if even better, is there a package I can get like THIS that will push the wifi calling to my phone?
If it is workable for me to flash one of these ROMs, should I be flashing a radio as well? Or any other tips to make this conversion work out?
Do not flash an LTE Note 2 modem on the non-LTE version, they have different hardware. I know there were some porting guides to modify ROMs to go from one to the other, so this won't be a straight-forward flash.
You should be able to flash t-mobile roms and get the Wi-Fi calling feature.
I am using it on my AT & T note 2 and Wi-Fi calling is working flawlessly.
Try Tweaked ROM from T mobile note 2 section and make sure you keep your existing RADIO/Modem.

Thank you both for the replies. I will try to get one working. Had some issues for a couple days recovering from trying Android 4.3... lol I like to experiment.
Curious as well
I bought this international version as well I live in the states and have been using it with att but now I'm about to switch to tmobile. I have rooted the phone but I am curious if I can flash it with a stock tmobile version of firmware (where ever that is) and use it with our services here. I understand Ill need to reset the counter and all that crap too. I have experience with rooting and installing CFW's but having a tmobile stock firmware that will accomplish things like wifi calling and ota updates would be very beneficial at least until that final firmware update is released then I will probably root it again.. real shame they wont let you OTA update just for a simple root but then again I guess with warranties and law suits and the chance of screwing up your possible custom firmware maybe its a good thing. Anyways point me in the right direction HAHA. The phone is amazing so far and works flawlessly with the towers here. Thanks. I checked the tweaked firmware for tmobile seems like it might work like you said but Im extra cautious at times and so I would like to know If what i stated above will work ok or not ???? Its not a huge deal if i cant have ota updates but yeah I would def like to have wifi calling and maybe some of tmobiles other things but yeah Looking forward to some advice
Same issue here

Normally? No. Not a chance since one is a gsm carrier and the other is a CDMA carrier. But its completely possible considering the fact people are unlocking Sprint s4's to use on straight talk, att, tmo etc. It actually has the gsm technology. Band wise tho, you should be okay but you might want to look into what bands the tmo uses and what bands Sprint uses. First you need to unlock the device, theres a few guides in general section for free unlock, but your biggest problem may be Sprint its self and getting them to add it to their service. Might want to start there first
