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)

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 have been scouring the internet for a while and cannot seem to find a way to revert my tablet back to stock. I tried the Lollipop firmware for a while and wanted to restore the tablet to possibly sell it. I can't find any method to recover it nor the files. The full model number is SM-T520NZKAXAR. It is the wifi only model. Can anyone help me please? I also currently have the TWRP recovery on it.
Thanks.

Thank you but I've looked there. I can't seem to find a match for my model number or any USA model. I read somewhere that the cellular south file will work but I'm a little hesitant to try flashing it. Mine is the WIFI only model.
If that were the case, it would either be a T525 (LTE), or possibly a T521 (3G). So anything listed as 'SM-T520' on Samfirmware should be OK. Having taken a look the US is not listed there. I have seen the Cellular South (XAR), as the possible option. But I doubt it has anything to do with any 3 ~ 4G connectivity, as the T520 has none.
It's possibly worth mentioning that these 'codes' (i.e. XAR), isa CSC Code. e.g. retail location in most cases. So assuming XAR is the USoA then this would be your choice.
Just one thing that you probably already knew, but is it really worth downgrading back to stock? The Knox Flag has already been blown. So NO KNOX on said Device ever again. Which would be about the only reason I could think for downgrading back to stock. Which IMHO would be a touch immoral if you wanted to resell it to someone who otherwise wouldn't have a clue.

def not mine was in deep sleep mode and i didn1t know it and now i use temasek ,it`s out of warranty ofc but bugs and error and lags from bull**** sa,sung apps are gone. cyanogen 13 modded flies like 5 times more than stock i play on tablet do a lot of stuff never had any problem in almost 1 year i can do offline backup a lot of perks.at some point when s3 will come i will sell it like this 32gb sd card leather case,i love this device.so no point going back to stock ever i always flash every new device
Thanks. I may give the cellular south file a try someday. The latest Cyanogenmod is working well. I was having problems with one of the older versions. The touch screen was acting goofy sometimes.
Have you tried https://samsung-firmware.org/?
Cellular South *is* the USA version. If you want to restore to US stock version, Cellular South is what you need. I don't know why they name it that way.

Hi all,
Would like to thank you in advance in taking your time in reading this post. Its my first time (and post) with the XDA forums. I have a few questions I am not sure if Im doing the correct thing so Im hoping for advice for the experts here in the forum to point me in the right direction.
Technical skills - never flashed a phone before but reading the step by step instructions available in the forums.
A few information with my phone to help with troubleshooting
- Purchased with no warranty overseas because they dont sell it here in the Philippines
- Phone came with the following specs
- Android 8 with Nov 1, 2018 patch
- unlock bootloader
- software channel - retcn
- Build number - OPXS27.109-52-10
- Baseband version - M8988_20207.117.02.41-01.01R NCD
Issue:
1. 4G Network - not working at all on the local network. It seems to be able to go to 4G but cannot make outgoing or incoming phone calls/ text or mobile data.
- troubleshooted by resetting phone, changing apn with no luck. Changing it to 3G only seems to make the phone work to make voicecalls/text and mobile connection
2. Random apps crashing - namely - grab (like uber) and spotify.
- tried resetting the phone (and installed just grab app only after reset but still not working) and cleared partition cache boot mode but still no change.
Proposed solution
- installing a new stock rom - should fix the apps crashing issue and 4g issue
- installing custom rom like lineage (discarded this solution because it will disable audio mods) - i bought the moto mods JBL accessory.
questions:
1. Based on this thread - (https://forum.xda-developers.com/z2-force/how-to/how-to-return-to-stock-sprint-t3694783)
- I wish to install stock rom but Im not sure which rom to use. Do I use USC version based on the phones current build number? - OPXS27.109-52-10 or can I change to a different US carrier like verizon ?(related to next question)
2. Is there anyway to change/fix the carrier frequency so it will start accepting 4g locally here?
- will installing a stock rom with a different carrier (i.e. verizon), will that change baseband and accept other frequencies or will I brick my phone?
- Or hope the stock rom with a different patch will fix it? Ive read in forums it could just be the newer patches that giving me issues. The one available for USC is version OPXS27.109-40-7. Upon checking my local carrier and USC band frequencies, both have 5 band with 850ghz frequency available. So Im beginning to think it could be a software rather than carrier issue
3. Because the phone came with a unlocked bootloader, does that mean I will never receive OTA updates from the stock rom? I will have to manually update it when android 9 comes out?
4. software channel - retcn - does that have to do with anything with baseband or installing stock rom? Does this help in any trouble shooting? Ive seen a few threads in the forums with builds with specific software channel in other threads with specific models xt1789 - 02 or 03 or 06. I dont know if that affects stock roms?
-----------------------------------
Maybe it would also help to show my local 4g frequencies and band number
Smart Band is here below
Frequency Protocol Class Band Number
700MHz FDD-LTE/LTE-A 4G 28
850MHz FDD-LTE/LTE-A 4G 5
1800MHz FDD-LTE/LTE-A 4G 3
2100MHz FDD-LTE/LTE-A 4G 1
2300MHz TDD-LTE 4G 40
Sorry for some newb questions and I welcome any other methods of troubleshooting or suggestions you guys can give me. I feel installing stock rom USC carrier is the solution to the problem after all the research I have done, but would like confirmation first from the experts.
Regards
Rj
On mirror.lolinet.com, 109-52-10 belongs to Retail Apac. The newest rom was uploaded is 109-52-12.
If your unlocked bootloader phone is still running the stock firmware, it will be notified when OTA comes.
I'm using an ATT with carrier unlocked so everything is fine to me. With unlocked carrier, you can use any mobile network if the phone baseband supports.
According to basic theory, if the phone was unlocked bootloader, it can be flashed fw from other variants (but there will be problem for each variant situation). It seems none of us here has done this yet.
- Check your phone model, it's on the right of the charger port.
- Open Phone, and type: *#*#4636#*#*. Choose Phone info. Check the preferred network type. If you can receive sms but cannot send, just update your SMSC number.
Most problems can be solved by flashing the stock fw.
Good luck!!!
Thank you
I didn't even know that site until you pointed it out.
I would be definitely be using the APAC software and try and flash the stock rom. I hope it would work and if not I'll try and flashing the older patch version.
Thank you
Will update you hopefully in a week as soon as I fully understand the details of flashing.

Just giving people update incase anyone is interested. I decided to follow this guide Step E (reflashing back to stock). It worked perfectly for me.
https://forum.xda-developers.com/z2-force/how-to/guides-bootloader-twrp-custom-roms-root-t3805737
As you guys know the original Build number was OPXS27.109-52-10. It turns out that was meant for model XT1789-06. It wouldnt be a big deal except my model that arrived was for XT1789-05
Regardless I followed the instructions and installed the latest firmware for OPSC27.109-52-14 for XT1789-06 (https://mirrors.lolinet.com/firmware/moto/nash/official/RETAPAC/)
Installation went fine and all the apps crashing issues went away. However 4G still didnt work.
I decided to see if installation the latest build for XT1789-05 under the link below would help.
https://mirrors.lolinet.com/firmware/moto/nash/official/RETAIL/
It felt more stable, apps not crashing, moto mods still working, and I was able to get get 4G working for internet and sms however phonecalls (both outgoing and incoming) still didnt work. 3G seems to be still stable and working fine at the moment in the Philippines. (note: I have updated APN)
I have decided to leave it alone as I got half my problem sorted (apps crashing) and moto mods still working. Can live without 4G as its mostly connected to WIFI at home and occasionally going out. Crashing apps was more important win for me.
Maybe once Android 9 officially comes out for the phone, it may fix the issue.
I have explored the option of changing the radioband but I heard of nightmares for some users when they switched to USA. I dont know what will happen if I switch to Australia radioband. (i left it to automatic at this time).
Maybe if someone else found the solution, would be happy to try it out.
I'm sorry for you when you still have some problems. My friends mostly use Z2F form T-mobile and Sprint. ATT and Verizon are less. But they work well for all functions.
There's another way you can try. It's the method for dual sim. For eg, you've a Sprint one. You modded the hardware and the 2nd SIM slot is now available. But current Sprint fw only supports single SIM. You can download a dual sim fw, extract it and copy-replace the modem from Sprint fw to dual sim one (I dont remember exactly what modem should keep, sorry). Then, flash the combination fw and the phone runs with dual sim. You can try a stable system and retcn modem or vice versa.

Nothing to be sorry about, actually really grateful for your input.
Already had a big win by:
1. flashing for the first time ever to stock rom and not bricking my phone in the process
2. all apps are now working
3. moto mods are working
4. alternative solution to 4g issue is available
Just letting you know the my variant already is on dual sim, and I was pretty sure the modem was wiped and reinstalled when I reflashed back to stock. I did find another thread of similar issue. Only solution was really to either change to 3G or fix APN.
https://forums.lenovo.com/t5/Moto-Z...ing-Incoming-and-outgoing/td-p/4068998/page/2
One user commented it could be a carrier issue. (see below)
-------
07-13-2018 08:41 AM
Hello, guys.!
I've been following this inquiry very close and I've arrived into a very accurate conclusion:
1. This is not a device problem! Motorola devices are not the problem. I've found that Samsung and Huawei devices also have the same problems.
2. This is definitely about service provider network. In my investigation, AT&T is the one having this issue alone.
3. This issue happens only in certain Mexican areas. For example, in Monterey this happens. I went to Chihuahua and CD Juarez just last 3 days and I was able to use 4G and calls without problems.
4. Based on the idea that only happens in certain areas at certain networks, I can only concluded that happens to certain devices as well. Brands, perhaps, as unlocked iPhone does not present this issue.
------
It could be something to do with Volte 4G calls. It has been disabled for the Xforce 1789-05 european models.
I think waiting to Android 9 may be my best solution though I may start try to start troubleshooting and focusing on simcards to see if 4g will work with other carriers.
I've got an ATT Flipout. I could make call and sms normally. But the network could only rise to E+, cannot be up to 3G (several years ago). The problem was phone hardware. The baseband was only available for US.
Z2F was the flagship, so its modem supported many 4G band for other regions.
As you mentioned, I think you should find out what carrier's band would suit your Z2F. Luckily, all Z2F variants have our bands.
Good luck, guy! And hope you'll give us good news!
You have the (05) dual sim variant correct? You're also in the Philippines right? If you look at this link you'll see all the bands supported for your variant, also you can check carriers in your region to see what bands they are using.
If you look carriers in Philippines like Smart you can see what bands they use.
A comparable carrier is Claro in Brazil.
They use the same bands on a GSM network. I would assume that Retail firmware would open those bands, but I'm not 100% sure and maybe the firmware you flashed doesn't. I do see firmware for RETBR (retail Brazil) and I know that (05) variants are used there. So maybe flashing a retbr firmware will open the bands needed since Brazil and Philippines use some of the same bands. I'm not 100% sure on this, it's just my best guess. You're welcome to verify the info linked and do what you will. I'd think the worst case scenario would be borking your imei and having to blankflash, but those tools are around here as well and so long as you DO NOT relock your bootloader you'll find that it is pretty hard to actually brick this phone. That's the best I can come up with to help.
Thank you

Your correct, its the dual sim 05 variant. I flashed the retail and I do get LTE data. It just the LTE wont work on 4G. So I dont think its purely a band issue because based on your link I have 3 supported LTE bands with the smart network. Its possible its something to do with carrier communicating with the phone. (APN? Volte?)
Question: will flashing a retbr on a retcn cause issue? Does software channel matter? Maybe I can give it a go, but my wife (who i gave the phone to) has been pretty happy with it. I dont think she wants another wipe on her phone. (i think i already reformatted at least 5 times already)
Update
I found this thread with moto z play.
Maybe this will work? It a method to open all baseband channels.

I don't know about all that, looks like a recipe for trouble. Are you able to make or receive voice calls? FYI you can go to apn settings, click the 3-dot menu and reset to default. That should pull your apn info from your sim so you should be good to go apn wise.
There was an old method called RadioComm. It used to unlock carrier for Razr HD (and maybe others Motorola phones). But it is more danger than flashing fw.
On my Verizon phones, no APN profile was showed. But on ATT Z2F, APN was automatically set (and showed) for each carrier.
Inbound and outbound calls affected

Unfortunately still a no go.
I have reset the network settings and used default apn as per your suggestion. I even copied settings from another phone using same carrier and used different calling apps. It's weird but when at 4g
1. Text work
2. Data works
3. Inbound and outbound phone calls doesn't work
Swap to 3g everything works
I'm still trying to convince my wife if I should flash to retbr.

Well if everything works on 3g then it sounds like your bands are fine. Sounds more like a volte issue. 4g works, 3g works, calling works, it's just no calls when 4g is on. Are you using an old sim? Have you tried the sim in another phone to see if you experience the same problems with 4g? Some carriers use different sim for different services. What is your preferred network type set to? If it's exclusively LTE, try setting it to LTE/GSM. It sounds more like a sim issue, setting issue, or maybe a registration issue.

I dont think its a old sim issue because its only a year old. But I am getting another simcard from another local network to test it out.
Will update with details.
Hello harkoliar, it looks like both you and I share the exact problem. And best of all, or worst depending on how you view it, I am in Malaysia with the same problems, Grab keeps crashing, among other apps just failing to work period.
Software Channel reads RETCN. 05 phone running an 06 firmware.
I noticed you tried to flash a RETAIL firmware, may I know which was the file you used, was it OPXS27.109-34-21?
I don't have much problems with the connectivity and using 4G. Perhaps it may be a difference between telcos in Malaysian and the Philippines.
Oh... And I bought mine from Lazada, where did you get yours. LOL

Still credits and thanks to the actual guys who did the guide.

Just finished flashing! So far so good, installing apps as we speak! Super excited!
Was your seller named Aukey? I left them a stinker of a review, lol.
Thank you so much for your experience and detailed breakdown of what you did to get right with your, now, wife's phone. :laugh::fingers-crossed::victory:

AUKEY owns coolicool. Same supplier keeps making the same mistake
Hi,
I have a XT1922-7 Boost version, it has been SIM unlocked by Sprint. Now, I no longer use Sprint.
I want to use the phone with T-Mobile or Verizon but there are a lot of bloatware & Sprint-custom settings which is very annoying . Right now, at least on T-mobile, it won't answer call on 4G/VoLTE, it drop to 3G on every call.
What is the best thing I can do? I suppose I can flash my phone to Retail?
I know my phone is Jeter. I might need to unlock my bootloader, flash TWRP, backup the existing Boost G6Play to a microsd card, but I do not seems to see any guide to go to retail, nor I see any Jeter rom to Retail.
Any advice? Thanks

Nope. Sprint Jeter is a different device. Not capable of VoLTE. It's not a retail device. Slightly different chip, different storage, different ram.

You can flash RETUS and it'll work. I've done it. Hell, I've even flashed the RETBR Aljeter firmware and that works too. I just can't get data without a gsm sim card. The bootloader and gpt.bin won't flash, but it shouldn't matter anyways. Just skip them.
Edit: RETUS Firmware.

Nice. Retail firmware is for 32 GB device though isn't it? It still ran?
Looks like USC is the only one that got a pie full firmware... Weird

Yep, retail is for 32gb. I just grabbed the USC Pie firmware a little bit ago. I think that I can turn it into a flashable ROM. I'm trying to figure how to work the modems though. USC will be missing bands, so I'm just going to DD the partitions I need for Sprint/Boost/Virgin from the soak test. I think that'll make it work.

I'd really like to know if it works for anyone else because I've never heard of it myself. Another thing that might also be related is, my phone came with a clear silicone case that had some numbers and MAN-S printed on it. I think it stands for manufacturer sample.

Mine definitely didn't come with a clear case. Odd indéed. I ordered mine from virgin Mobiles website.
Maybe you got a review unit?

I'm think that's highly probable. There was an issue where a bunch people got Boost models inside generic white boxes, instead of Virgin in proper packaging.

I flashed the US Cellular pie update on my 1922-7 (which I had on Sprint and after my time with them was up they unlocked the SIM slot). It works no problem.
I used it with t-mobile for a week and everything seemed to work fine with it. It also works fine on ATT as well.
Right now it's got a t-mobile sim running Descendant Treble ROM - A only ARM GSI. Works like dream. I never tried VoLTE before I switched from T-Mobile and ATT doesn't offer it in my area.

Same here. I tried it a little while ago. I just can't update my profile or PRL on it, but LTE did work.

I should ask virgin to unlock mine. Should be eligible by now. Who can remember dates.... Not me! I feel old today. 42, but most ppl think I'm closer to 32. But today I feel 52. LoL, sort of....

Update your device to PIE, unlock your bootloader, flash the newest TWRP build that works with PIE, download the A Only ARM build, unzip it, you should have a system img. Boot to fastboot, fastboot flash system system.img, boot to TWRP, flash this https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389. Boot the rom one time. Then boot back to TWRP and flash pico gapps for Pie. You'll have to get your device certified with google to get google apps to work.

Flash whatever version of Pie is out for your model. Your Model should be XT1922-? where the ? is a number. For example mine is XT1922-7. The retail US version is XT1922-9 etc
There should be a Pie update for whatever model you have. Flash the correct model and you should be good.
I live in Canada. I purchased an S20 Ultra off a seller on Canadian best buy (open box). I assumed it'd be a Canadian variant, but it was an unlocked US version (U1 firmware). OK whatever, but it meant my Samsung Pay doesn't work, along with a few other calling features.
I downloaded the patched Odin, downloaded the G988W firmware (with XAC CSC) with Frija, added the appropriate files to Odin (used Home CSC), and flashed it. The flashing itself went fine, but when I went to re-insert my SIM...nothing. It didn't even error out and say "No SIM Detected", I just had no coverage, and in SIM manager, both slots were empty.
Freaked out, and eventually flashed back to G988U1/XAA and thank Christ it works now. But my question is...why?
I dug though this forum before doing it to try and anticipate any issues. Followed the instructions to the letter, nowhere said this would be an issue. Couldn't even find any relevant support questions for this issue on this model. Not sure if it's a new development, but I absolutely don't want to risk messing my phone up further if I reattempt.
Bonus question: My CSC info is: XAA/XAA,XAA/SPR. Does that mean that it was originally a Sprint model phone, someone's flashed the firmware to an unbranded version, then sold it off as New (Open Box)?
You can't just flash a firmware from a different phone. The hardware is different, so the way to communicate with it is different. You're lucky it even booted, I wouldn't have expected that even. You're simply stuck with the original firmware and CSC list. Or, maybe you could try with custom ROMS but I wouldn't be so sure about it. Either way, you'll have to use a ROM/firmware that is built for your phone (G988U1).

Huh I thought the actual hardware between U1 and W was the same? They're both Snapdragons. Besides I've seen other posts of people doing the same (tbh, they were going from W to U1, but still)

Oh but you CAN.
U, U1, and W have all been cross-flashable ever since Samsung first introduced universal hardware, starting with the S8

Probably. Very common for online sellers to do.
The key probably lies in what the CSC shows as after flashing W firmware. If it stays as XAA, changing the CSC manually to a Canadian one could possibly make it work

I thought so too, lol
Any thoughts on why my flash caused the SIM issue? Did I maybe just install the wrong version? I don't think I did, I used Frija
Some further research led me to the subject of accidentally mucking up the modem firmware which I might have done

I Just did exactly the same and got a tmobile variant but want the W preferably the samsung factory rom not a carrier one. Which guide did you follow? I found this for the 21 Ultra and expect the steps to be similar https://forum.xda-developers.com/t/...-samsung-unlocked-bloatfree-firmware.4224423/
What calling features don't work in Canada? I have a W variant, live in Canada, and want an U1 to get esim working. I am also looking for a guide to follow to flash my phone.

Samsung Pay doesn't work - that's a big one for me, it's a pain in the **** losing that. Will only accept US ZIP codes when setting up.
Caller ID doesn't work
That extra info you get when texting (like seen/read stuff) doesn't work in the native Samsung text app, you have to use google messages (yeah, no)
I'm sure there's other stuff but those are the main ones
