Can I activate a rooted phone?

If I'm on a custom ROM?

yea, why wouldnt you be able too? just log into your google account. google themselves have no issues with us having root.

Well it's not activating is all I know. I was on Verizon support and they're kinda stumped so I was going to flash back to my stock ROM after a backup. Hopefully that solves this issue and I can restore it in the next 10 minutes.
Doesn't rooting/ using a custom ROM void the warranty or whatever?

I'm still getting used to these LTE phones, but I believe that simply inserting an activated Verizon 4G LTE SIM card will automatically activate the device to be used on a cell network.
Someone please correct me if my information has errors.

Not for me apparently. I get 4G but can't make calls.
I was on the Verizon support but... didn't want to say "Hey I rooted" that used to void the warranty.
edit: After a factory wipe/ unrooting/stock it activated

[Q] T mobile SG3 locked to AT&T

I recently flashed my 1st Rom (CM10) on my samsung galaxy s3 t999) and thought everything was fine till I tried switching from At&t back to t mobile and noticed the sim wouldn't work so tried 2 other companies straight talk and simple mobile and they didn't work either but they work in my unlocked iphone.So what could be the problem I tried different roms and even checked my imei and its clean.

Anybody?

Not sure what it could be....It is unlocked because you were using it on AT&T right?
Best I can say is to Odin flash the stock firmware and try it that way. Then if needed, try going through the steps laid out in the unlock thread in the General section. If it still isn't connecting, call T-Mobile as it sounds more like an account issue than a phone one....

Did you change APNs? That might cause it.

This. Or if the Rom came from the AT&T forum it may have come with the wrong ones too. Either change to a T-Mobile apn or flash one of the roms from here if this is the case.
Thanks DJ, didn't think about that!

Looks like you installed an AT&T ROM. Can't you just pick a T-Mobile ROM you want to flash and install that instead?

We don't do recomendations on XDA. Such threads are forbiden because they ALWAYS revert into hapless arguments over what the 'best' rom is.
Truth is there is no best rom. Only the rom that is best FOR YOU. You will have to read the ROM threads to narrow the field down and try a few yourself.
Although the odds are VERY strong that whatever ROM you had for AT&T is available in the T Mobile version as well.

Do you have a T Mobile SIM card in the phone?
When you say you switched to AT&T I'm not really clear on if you just switch to AT&T software or if you actually used it on the AT&T network.

I'd say flash a stock rom in Odin to do a full restore to factory. See if that clears your issue. If it does it's probably safe to reroot it and go back to a custom rom of your choosing.

[Solved] [Q] Bought new S3 from Amazon, can't update

I recently bought a new "Samsung Galaxy S III 16GB SGH-T999L 4G LTE White - T-Mobile" from Oakland Wireless via Amazon. This is for my fiancé, to replace her broken iPhone 4s. After popping in her T-Mobile sim card, the phone seems to work fine. However, the WiFi calling feature seems to be missing and when we try to perform a software update it ends with "process failed". The installed Android version is 4.1.1.
She went to a T-Mobile store to see if they could help. They were also unable to get the phone to update, and eventually told her that it would never work simply because we didn't buy the phone from T-Mobile. They also told her it would only be a talk and text phone, and wouldn't get data service. However, this last part is clearly false, as she has been using data without any problem.
Does anybody have experience with this issue? Were the folks at the T-Mobile store correct or mistaken?
Also, assuming they are correct and the phone can't be updated over the air, can I just download and install a stock ROM with the latest version and WiFi calling? I have a custom ROM installed on my Galaxy Exhibit, so I am familiar with installing ROMs, but my fiancé doesn't want a custom ROM, she wants stock.

Look in the t mobile s3 section there should be a Odin file you can flash (stock firmware)
Sent from my SM-N900A using XDA Free mobile app

Well first of all the T999L released with 4.1.2 so something doesn't seem right, and it may be why its not updating. To get a better idea of the phone model, can you post a screenshot of the about device section? And I assume you are not rooted correct? Download this app https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo scroll to firmware info and post it here as well

Thanks for the replies!

I didn't see any stock stuff in the tmobile s3 ROM list, but I did a little more searching and found this thread with stock firmware and OTA's:
http://forum.xda-developers.com/showthread.php?t=1949687
Not sure if I should try to do the OTA update or one of the complete firmwares. Any idea why there is no OTA update for 4.3?

Hmmm. Maybe I got the version wrong or maybe it's not really a T999L? She isn't here with the phone right now, so I'll have to get back to you.

I stopped posting the OTA's simply because they're next to useless for us. Fladhing the firmware via Odin has a much greater success rate snd OTA's are notorious for causing all sorts of problems. Just wasn't worth the trouble to post them anymore.

I attached the screenshots from the phone info app. Looks like maybe it's not the LTE model after all? I looked behind the battery, and it also says SGH-T999 with no "L" on the end.
The strange thing is that it shows an LTE mode in the network settings. However, I've never seen it actually use LTE mode, even though T-mobile says it should work at our location (Seattle). Using the Ookla speed test app, I get ~4 Mbps down (the same speed as my Galaxy Exhibit).
I'm thinking about returning the phone if it is not the correct model. I'm curious though, if I try updating the firmware and it doesn't work, can I restore everything exactly to it's current state before I return it? I don't want them to refuse the return because I messed with the firmware.

Ok looks like you got a Frankenstein phone.. That's an at&t bootloader with a Canadian product/model name & T999 build that I've never heard of.. I would just return it or ask for an exchange, not worth it to keep messing with it

Yup. Another one! And its got a csc from the I9300! The LEM build, if I remember right, was the original stock 4.0.4 firmware. But there is way too much conflicting info there for me to be comfortable recommending much of anything.
I just installed that app to make sure it wasn't giving bad info, and it is showing everything correctly for mine.
As for the LTE showing up in the menu, that isnt too uncommon. If you want to know what you are really connected to, check Settings, About Device, Status, Network Type. Best to do this during a large download.
But aside from it being a franken-phone, everything that is related to the T-Mobile model points to it being a non-LTE T999.

Yeah I noticed that too but guess I forgot to mention it ? so odd how out of nowhere there this wave of franken-phones going around

Thanks for everyone's advice. I'm going to return the phone.

Probably the best choice. Its just more trouble than its worth imo.

I-747 (AT&T) with T-Mobile ROM (For WiFi Calling)

Hi all, I have a AT&T I-747 S3 that is running CarbonROM (Aosp) at the moment. I'd like to flash a T-Mobile ROM onto it, so I can use native WiFi calling with my T-Mobile SIM Card.
Baseband: I747UCUEMJB
Bootloader AP SWREV - 2
I have the 4.3 Bootloader because I took the OTA update a few months back.
Does anyone have a T-Mobile ROM suggestion that will work and has WIFI calling?
Thanks all

All stock based T-Mobile touchwiz roms have wifi calling. Not sure itll work, but just give any of them a try. (NC2 is our latest build. Check out StockMod)

Thanks for the reply. I was concerned about bootloaders etc and didn't want to mess my phone up too badly. I was hoping someone would know what actual ROM would work with my specific modem/bootloader, since I think AT&T is much more locked up than TMO is.

As long as the ONLY things being flashed are the system and kernel, everything should work fine. You may have some minor connectivity issues, but I kind of doubt it since youre using it on T-Mobile's networks. Still, it is a possibility.
Anyway, just mske sure you never flash any base (or full) firmware or modem that is not specifically for the I747. Flashing the T-Mobile modem most likely just wont work (as opposed to bricking), but flashing T-Mobile firmware will almost certainly hard brick it.
Depending on the rom, you may need a d2tmo recovery. You probably wont run into that problem, but it is a possibility. It should be completely safe to flash the d2tmo TWRP or CWM recoveries if required though.
let me know if you have any other questions. also let us know whether or not wifi calling ends up working. Good luck!

I know this isn't the right place for this but I saw doc holidays name and know he's the man.but I have 4.1.2 and get get any kitkat rom to flash. I keep getting all types of error messages. How can I accomplish this feat. ..thanks and sorry again...please help...

Errors in Odin or recovery? Either way it would help if you could state them

And are you talking about touchwiz or cm/aosp roms?

I'm sorry, its been awhile since I've been on here. In recovery. It usually says error in sd card/ ...error 7. And also I can't seem to find a flashable boot loader. But besides that I can even get kk to flash period...thanks again

If you are trying to flash Touchwiz it wont work unless you Odin flash the 4.3 firmware

Usually cm...but the flash will give you an error and will abort installation because a bottloader isn't there...?...its not that my phone won't boot, I mean as soon as I flash it it will say opening package/installation...Then say something to the effect of error:/sdcard blah blah blah (error 7)...then say FAILED...

If its a Status 7 error it means you dont have a bootloader matching what they wrote into the updater-script. With CM it means its either too old, or too new. They dont update their scripts so when new firmware comes out it will no longer flash, regardless of whether or not it will work ok.
Try searching the rom thread to see if anyone ever posted one with a fixed script.
Or you can edit the asserts yourself.
