Help brand new D6603 on ATT getting limited service. - Xperia Z3 Q&A, Help & Troubleshooting

So I just bought a new Z3 replacement for my older one on Ebay. The problem is that it's not the same as my last one. The new one doesn't connect to any sort of ATT internet no edge, hspa, or LTE. I'm able to make calls and send sms but no mms. the APN settings are identical to my other Z3 which works just fine. Another thing I found strange was that it's running android 4.4.4 and It says it's up to date. Any ideas?

The fact it's stuck on 4.4.4 is not good.
What model is it? D6603/53/33?
What does the about phone section of settings say?
You can try flashing the latest firmware for it via flashtool and that should get it all working.
It will update the baseband etc which should help with mobile data

The phone and the box say D6603. I was thinking about flashing it but decided not to thinking that I might return it. but I'll give it a shot.
I might be crazy but I had another theory, that it's actually a different model flashed with a D6603 rom. I'm not sure if the bands are limited by hardware or software, it's just a conspiracy theory I have.

That's possible.
The model number shown in settings is determined by the build.prop so if it's a D6603 ROM it will say so.
I'm not entirely sure how you could determine the model.... And the phones are almost identical in hardware apart from the D6633 which has the second SIM slot.
What I don't understand is why it is stuck on 4.4.4.
If it is genuine then flashing an up to date FTF should be the solution.
Tbh i would be safe and return it.
I don't trust second hand phones personally because more often than not the seller doesn't disclose the full history of the device.
You can try flashing it but if you make it worse it gives the seller an excuse to say you can't return it.
Message them and explain the problem and see if they will accept the return

Getting Cell Service with NO SIM! And some other guys number ! Help

I just bought a phone the guy who made no mention of the fact that it was rooted when I bought it. What is worse is he mentioned that his GF worked for Verizon, which did not seem to mean much at the time. Knowing that here is what i'm dealing with.
I was in a rush when I checked out the phone as I had to meet another person to pick one up for my wife as well. It's the sch-i575 in white 16gb. After having a minute to look at the phone it turns out he had Paranoid Android flashed and the phone was rooted. CRAP! Not what I was looking for and he was not upfront about it. The incredibly strange thing was that with NO SIMCARD the phone was getting 3g signal! I spent all night trying to unroot \ undo what he did. I managed to use ODIN to get back to the stock rom although I think it's still a rooted one since I still have the super user app. I got a sim card from verizon but since it was rooted I did not bring the phone in and when I tried to activate later it would not activate. My wife's by the way is working flawless and when I put my sim in her phone it works fine as well. I had to put the sim in my wife's phone and it activated there. Here is the crazy thing, with or with out a simcard the phone makes calls and has 3g internet only but when I make a call it uses HIS NUMBER!! I'm not sure what the hell to do, what could have he done? Any ideas? Please all help is appreciated! I did not think this was even possible for the phone to function w/o a sim. I'm worried about taking it in to Verizon because of the funkiness. Ty again for any insight...

I thought the I575 was an old slide phone. So A. your in the wrong section of the forum since this is Verizon's S3 or B. you mentioned the wrong device number? I saw phones before working and running on networks without sim-cards but that was years ago. If it is an S3, you sure it's a Verizon device? Also since you see 3g....can you browse around in the browser or make a phone call?

Yes, it's a galaxy s3 16gb in white. It looks like currently I was using the tar66 using ODIN. I'm reverting back to the bone stock one now. As far as the models go isn't the SCH-I575 the Verizon version of the S3?
I'm waiting on the stock unrooted rom to take through ODIN and will report back. Thank you for taking the time to try and help.
Ohh, yes the internet works and when I make phone calls with or with out my sim in it makes calls successfully but the other guys number shows up. What the heck did this guy do to the phone!
Our model is the SCH-i535

You are obviously absolutley correct. I'm frantically trying to figure this out. I have flashed the stock rom and don't have super user anymore. The problem persists with the guys number.
Could he have flashed a custom kernel and modem or does reverting back using the stock rom cover all that ?

The one i linked covers all that and completely erases all data on the phone. Did you insert your sim after the stock flash?

I just double checked and I had the I535VRLAG1 version, yours is the I535VRALF2 in the link you posted trying this now. The crazy thing is that it even says that the sim is activated with MY number! but the calls are still comming from him. I even tried wiping the device and clearing the cache. I also tried to JUST flash the modem with VRLG1.modem.tar.md5 and nothing :\. Waiting on the file from your link to download and will try that.
Is it possible that this is being caused by something on Verizon's end? The phone ( with out the SIM ) is registered to him somehow? I know this is not normal but because his GF worked for Verizon could they have done something funky?
Yeah its definitely possible its from something she did to the phone but most likely nothing from Verizon's end. Does the IMEI number under status match the IMEI number under the battery?

Yes IMEI is the same in the OS as behind the battery.
The curious thing is that on the same screen in the OS where you find the IMEI there is also a field called Network and it says " Unknown"
It also has things like:
Eri v : 5
Mobile network type : EvDo-rev.a:8
The thing I keep coming back to is how is it possible for this phone to make calls\ have data with out a sim?
Starting to really think I got cheated
Cheated? Sounds like you have free Verizon service.
Roll with it. If you really want a bill you can have mine...

Just did and the same thing happened. I went to the Verizon store and the guy there had no idea and got me in touch with tech support from the store. They were dumbfounded and flat out said that what is happening is impossible. "It's impossible to make\receive phone calls with out a sim unless they are emergency" I harped on the fact that I am making phone calls as one of their other customers and that this is a big deal. In the end since I had the insurance and extended warranty they will ship me a new phone.

[info] s3 sch-r530 u/c/m/x

[I'd like to create a thread to collect information for all variants of the R530. I'll update this first post with additional information people give during discussion. Sorry it is here in the Verizon sub, but this is the closest model]
The SCH-R530 is a special flavor of the Samsung Galaxy S3 with sub-favors: (you should probably puke now)
SCH-R530U is a US Cellular variant
SCH-R530C is a Cricket variant
SCH-R530M is a MetroPCS variant
SCH-R530X is a Generic variant
I suspect these are all the same hardware, but just different ROMs. I would like to confirm this.
I would like to know and post the newest firmware versions for each. (at least the names, if not the ROM files themselves) I'd like to know if ROMs are compatible, if modem firmwares are compatible, if bootloaders are compatible. The small community of owners need to pull together as much as possible.
Model -- Hardware Version / Firmware Versions / Baseband
SCH-R530U --
SCH-R530C --
SCH-R530M --
SCH-R530X -- R530X.01 / JSS15J.R530XWWUBMK4 / R530XWWUBMK4
Please post if you can add to this information!
I'm working on my dad's SCH-R530X (Generic CDMA). It was on a regional CDMA provider that he was not happy with -- he paid $500 to them in January for the phone. Edit: Today, he's on PagePlus, but without data for some reason.
Concerns (that someone may be able to help me with):
Once you go to KK 4.4 you can not go back? Your bootloader is updated and will not boot 4.3?
I'm running 4.3, can I root -> replace recovery -> custom ROM ... without tripping the KNOX warranty void? I've read that saferoot will not trip KNOX?
This phone seems to have an odd Call Audio Quality problem. While listening during a phone call (on the R530), the other party's voice cuts out. Specifically, it cuts out when the other person isn't speaking in their mic close enough or loud enough. It's as if the R530 is filtering out anything under a certain volume level. I've turned off Call Equalizer and Noise Reduction to try to solve this problem. I believe I've read people say a firmware/ROM update from US Cellular fixed this problem.
So you can see, I have some constraints: Still in warranty and don't want to void it by tripping KNOX. Want to try a newer firmware for call audio problem. Don't want to brick phone with incompatible firmware, unless US Cellular will work on this X/Generic phone.
Help would be appreciated.
I do have the USC and Cricket variants but the USC version is soft bricked.
HW: R530C.01
Firmware: JSS15J.R530CVVUCMK3
Baseband: R530CVVUCMK3
Also fyi, this and the USC version requires a sim card.

Thanks... I'll add the info. I think I'll make a spot to record if it has a SIM slot too -- as my 530X does not have a SIM slot and was labeled with a little sticker "3G CDMA"... but the MEID starts with a "9" and LTE visible in DFS.

I have a regional version of the s3 as well, d2xar (sch-r530x) on Inland Cellular, primarily based in the north west US. as far as i can tell, i havent dissasembled my phone to see if there is a lte radio, in the original build.prop for my phone it is disabled on boot so it will not consume power since it is not being used. thus the 3g cdma only sticker. for the us cellular version i do not know if there is a kitkat firmware but if there is there is always the possiblity you will not beable to go back. as for the generic version it is only on 4.3 right now. eitherway the higher the bootloader version is better for customroms due to recoveries and features working better. as for saferoot i dont remember if it trips the warranty bit or not since ive long since written a custom recover to the device which tripped it but i do know itll make the stock rom list itself as custom in the settings after being rooted. also something to keep in mind with a custom rom is, unless you have the apns for your carrier eg, pageplus, usc, ect. you will not have mms capabilities. Im still tearing my build.prop and apn back up apart to see if i can include some of that info into a custom rom to fix mms, or a recovery that will inject it after a rom flash.
Update?

Last I checked there was a bug with the d2lte builds that break the ability to set apns... I made a cm10.2, I think, build that allowed changing the APN. Um if I remember right the physical design of the d2xar has hardware similar to the Verizon s3. I still don't know if there is an lte modem in the phone since there doesnt seem to be a sim card slot, though there maybe an integrated uicc. I haven't played with it much since I switched to using my nexus 5 on T-Mobile.

I got to the service mode settings, which oddly enough it listed GSM and CDMA. Quite weird. To get there was even weirder. Sadly the D2xar doesn't support TWRP Recovery, and the only one that works is CWM by Philz.

Yah I noticed that to when I was digging around for apns for my old carrier. As for twrp I got around that problem by building my own version using cyanogenmod and the d2lte device files. It made cyanogenmod delta updates possible on the d2lte build. Which are really nice. My source is floating around github, though you'd have to do a little digging to find everything. I do have precompiled twrp images on my webserver that I try to keep up to date for my friend who's brother has the same phone. If you go to my site its safe to ignore the certificate warnings, I have it set to force HTTPS and the reason the warning pops up is because I self signed it instead of paying for a company like verisign
Sorry for my superbly late reply. I've done a ton of digging with this phone. Turns out it only supports Evdo. So no LTE sadly. Even worse, using the Test Menu I can't bands to USA bands, only the (800 or 850?) Hz Global band. I can't get a connection. Well. The bars are listed as 2-3 generally, but it says "Roaming Indicator Off". I have the latest and only baseband, too.
(Wow. After two months of fiddling, as of typing this, I turned on cellular service, which is usually in Airplane mode, I got a " 3G" connection for the first time. Only for a second.)
I don't think I'll be able to switch this over to Straight Talk any time soon, though. I'll check your GitHub soon for that TWRP.

Yeah, just of now I've been unable to re-acquire the "3G" that caused me to have a boost of hope. Now even when I attempt calling which it usually would bring me to the Verizon automated system, asking to make a collect call, since around here is primarily Verizon, I can't even get it to call. It now states that no mobile network is available, even when I have 2-3 bars.
You have no "3g" because your keys are wrong. Y'all need some QPST and see the whole logon process and baseband messages. Then you can really troubleshoot your phone.
I have a Verizon Samsung Galaxy S3 on the Straight Talk network. I check for software updates and it tells me the software is up to date however it says my phone is running off of 4.4.2 instead of the Lollipop or the one just under. Does anyone know if Lollipop 5.0 or 5.1 has reached the S3 yet? Or how to manually update my phone software so its not so low?

you will have to root, trip knox and lose your warranty... there is no way to go back. on verizon you may be screwed if you have signed/locked bootloaders. search on XDA about unlocked bootloaders for verizon. also: http://androidforums.com/threads/verizon-verizon-bootloader-unlock.856221/
aaaand... make sure to back up your mmc boot partitions so you can debrick if you mess up.
p.s. prepare to learn a lot of technical things. if that sounds annoying and you don't want to spend a lot of time on it you might be better off buying a used phone.

Do you have any idea if the 530c and the 530x share a similar partition table? If they do then I can pull the one from my 530x

Getting AT&T features to work on unlocked S9+

Does anyone have a definite solution to this problem? I've read many opinions but haven't run across a solution. I have a Samsung unlocked S9+ running official AT&T firmware and userdata but the carrier specific apps and features still don't work. The best infomation I've found is that the IMEI numbers of the unlocked devices are not in AT&T system so the features/apps won't work.
If this is the case, has anyone had any luck getting AT&T to register their IMEI and get the features working?
What worked for me and others (see the at&t fw thread) is to call or chat with AT&T and give them a imei from a carrier branded phone(with your sim in, though this might not be required). Tell them you are trying to get wifi calling to activate and it is failing at the provisioning step and they will input your imei and it will reprovision. Then pull your sim and put it into your s9/+ running at&t fw and it will allow volte, wifi calling and call protect to work (these are the only ones I use).
Good luck
I talked with someone in AT&T technical support and they remoted directly into my phone, reset all app defaults and network settings.. This of course didn't fix anything so they opened a trouble ticket. They told me my IMEI was in their system and was OK. Haven't heard back yet.
why not just flash ATT U firmware?
I'm running AT&T official U firmware G965USQS2ARF4. What just occurred to me was that I didn't do a factory reset before or after applying it via ODIN.

Does anyone have a definite solution to this problem? I've read many opinions but haven't run across a solution. I have a Samsung unlocked S9+ running official AT&T firmware and userdata but the carrier specific apps and features still don't work. The best infomation I've found is that the IMEI numbers of the unlocked devices are not in AT&T system so the features/apps won't work.
If this is the case, has anyone had any luck getting AT&T to register their IMEI and get the features working?

I talked with someone in AT&T technical support and they remoted directly into my phone, reset all app defaults and network settings.. This of course didn't fix anything so they opened a trouble ticket. They told me my IMEI was in their system and was OK. Haven't heard back yet.

Yes your IMEI is in their system. But it's not an IMEI from a branded ATT phone. You have to have the IMEI from an ATT phone like others have said, and like i had to do or you will not get the features, no matter what firmware you flash. This has been discussed in many threads. You have to have ATT change your IMEI in their system.

Wont help unless you have a 965U or the IMEI from an ATT phone . ATT Features will not work on 965U1 IMEI. AT&T told me theses features wouldn't work on an unlocked phone and asked if i had the unlocked version. I told them no, it was an ATT phone i bought from Best Buy and it has an ATT logo (not the truth, got it from Samsung) and that i read in the forums that there were some issues with the S9 and that changing the IMEI fixed everyone's problems. I said i had my s8 here that everything works on and she said it's worth a shot to try and she changed mine in their system to the IMEI from my AT&T Branded S8 that i provided them. 965U1 has worked flawless ever since. All features work.

sounds about right.. i mean you can switch csc while on U1 depending on the sim card inserted but U1 isnt meznt to have all the carrier crap they need for the special features to work so u get the bare minimum..
while on U firmware, it seems the csc doesnt fully switch like they did on the S8 devices.. i tested this on my sim unlocked vzw s9+ with an att sim and a sprint sim and although data and calls worked,it stsyed on verizon bootani and bloat etc etc no matter what i did.. before on s8 devices after a reset it would have changed the boot ani,bloat and woulda had all the carrier features..
im also surprised they changed your imei lol.. i thought that was illegal lol.. i guess if the carrier does it then its fine haha

Hard to believe that they would just accept another IMEI and register it to your phone. I thought these were all unique numbers that couldn't be used on more than one device. How did that change affect the phone that originally had the branded IMEI?

Didnt affect original s8 i used at all. or the s9. I replaced the s8 with the s9 when it came out so i just used the sim out of the s8 when the s9 arrived. s8 is just a spare phone now. I asked the operator if this would disable the other phone that the IMEI came from and she said no. I put sim from s9 in s8 afterwards just to test and it worked fine. They arent changing the IMEI of your actual s9, it still shows your original IMEI in your phone settings. They are just using the IMEI you provided on their end. What is actually going on behind the scenes i dont know. Maybe somebody that works in carrier support or may just have knowledge on how this actually works could chime in. I'm guessing they just use the IMEI to activate the features, since the unlocked one isn't eligible. I saw a better explanation in one of the firmware threads, if i run across it i'll post the link.

I will reiterate what is said above and clarify my post. You aren't asking the support team to change your phones imei. I think as stated previously that is a forbidden/illegal maneuver. The support request is to change the imei which is active in the at&t system as only carrier branded phones are able to use certain at&t features.
If you have an old AT&T phone its imei can be used to "trick" at&t into activation/provisioning. Then you can put your sim into a U1 phone using at&t firmware and use carrier specific features.
Hopefully, this is easier to understand and clears up some of the confusion I may have introduced in my original reply.

I presume I can use the IMEI from another brand of working AT&T phone such as an iPhone 6S (in this case, my wife's)?

Another thought... Say I get an old Galaxy S6 which uses the same size Nano SIM as my S9+. I move my S9+ SIM to the S6, update it to the latest AT&T firmware and enable WIFI calling. If I then move my SIM back to my S9+, will the carrier features now work?

This is exactly what I'm doing. I use an older LG phone and the sim/IMEI then swap it to my u1 with AT&T fw after the device is provisioned.

Glad to know that works. I can pick up an old AT&T S6 pretty cheaply on ebay. Guess I'll give that a try. Thanks

I previously had an AT&T branded S8+ with the same SIM that I'm using in the unbranded S9+ but I guess I never provisioned (enabled) WIFI calling. Dunno.
The "trick" of giving them an IMEI from an ATT branded phone doesn't usually work any more, maybe it used to, years ago.
This is why I won't buy OnePlus phones any more. I love their devices, best bang for the buck on the market, but no amount of my fiddling would get ATT to recognize it and provision VoLTE... so no wifi calling, no HD calling... when you make a call, your data drops to 3G, etc...
My Essential, somehow was on their "BYOD" plan and so it would give me VoLTE and HD calling, but no wifi calling. No wifi calling is stupid, because you aren't using their network at that point, so why should they even care?

"maybe it used to, years ago"... That doesn't apply in this context does it as carrier features VOLTE and Wi-Fi calling weren't even in existence years ago. And I'm not sure you have to give them anything. The claim by some is that just provisioning the features with your SIM on a branded device is enough.

And as someone who has repeatedly tried it, it doesn't seem to work. You can give them an IMEI from another phone, but it usually doesn't work. Either the IMEI is "on their list", or from a phone that is on the BYOD list, or it isn't. It's not the phone's fault, it is that AT&T is kinda being dicks about this... They want you to buy their phones, because most people sign a contract to get the cheaper price, or use their NEXT financing to spread the costs out. That creates a barrier to exit for most customers and protects AT&T's revenue stream from monthly invoices.
While bringing your own device makes them just as much money from the monthly bill, it doesn't help them "retain customers by locking them into a contract", so they usually don't give you full functionality...
I have had a working SIM from an ATT branded phone that was properly provisioned, popped it into my other device, and VoLTE went away. I would call them up and give them the IMEI from the phone, or one that I know worked, and still no go. The one exception was the Essential, and that was because for whatever reason, Essential went to the effort to get it on their BYOD list.
Trust me, if it was easy, I would be doing it and buying OnePlus phones exclusively every 6 months and that would be the end of it. LOL

Custom roms on SM-G930W8?

I will start off by saying I am not experienced when it comes to custom roms. I currently have an G930P running stock, but want to switch to a custom rom for better privacy. I did some research and was disappointed to find out that I can't do that with the G930P, so I ordered a "renewed" G930F from Amazon. It arrived today, but instead of the model I ordered, it appears that I received a G930W8. I know this is still an Exynos model, but I want to double check to make sure there aren't any issues I need to be aware of before trying anything with this model. I really don't want to brick a $200 phone. I'm leaning towards Havoc OS for my rom if that makes any difference.
Another question I have is whether this phone will work on T Mobile/Mint as my plan is to switch to them from Boost because I found out I can get a lot more for my money that way. I haven't been able to find as much information for this model as I did for the 930F.
Thank you in advance for any help.

So the G930W is customisable and anything you can do with an G930F you can do with G930W. The only thing you need to check BEFORE you do anything is to check network band compatibility. Look at the "Network" specs for both phones side by side and make sure the bands you need for TMobile are listed.
Also there is obviously a scam with these phones always being described as G930F but turning up as something else. It's true exynos models are easier to modify but you still need network compatibility as I've mentioned.

I checked compatibility with Mint/TMobile and it said 100% for 2g and 3g, but only 60% for 4g. Went ahead and popped in the sim card that just came in the mail and followed the instructions for activation, all except for one step which said to turn on mobile data, which I couldn't find in the settings.*This did not get me connected, so I looked around more in the phone's settings and found "Network operators" under the "Mobile networks" page and hit "Search networks." This pulled up 8 different options, all called "Mint." I tried "select automatically" but I got a message saying I would have to manually select the network. So I started going down the list, trying each one. Some of them would not connect, but a few did and would show several bars of signal. But when I would try sending a text or making a call, I would get an error.
I should probably also mention that in addition to frequencycheck.com, I also checked the phone's compatibility via Mint's own website which asked for the phone's IMEI and it showed as compatible, but also said this wasn't a guarantee that it would actually work.

Hi there @ekjf, I was wondering if you tried installing a custom ROM on your G930W8? And did it work?
Thanks!

I have a buddy who works on cruise ships. He had purchased a OnePlus 8T (KB2003) he is back in India now and unable to use any SIM.

I think its a network band issur. Is there a way to switch or unlock them?
Since it's your buddy who is having this problem, not you...
You should ask him to contact the nearest OnePlus official support center.
This gives him the chance to describe what happened exactly to a tec pro and the best chance to solve his problem without losing any data on device.
If he can't do that, ask him to backup any useful data on device, read any useful posts here [ https://forum.xda-developers.com/f/oneplus-8t-guides-news-discussion.11585/ ], and try to get his firmware a re-flash.
My buddy did go to the service centre in India, they were pretty much useless.

Is your buddy you?
If not, tell him to learn how to unbrick his phone...
Lol, I find your comments funny. No I am not my buddy and the phone is not bricked, EU, and India have diffrent LTE, 5g bands and he didnt realise that while making the purchase. Now with the Indian simcard the phone doesn't connect to the network. And if you dont have anything but a snarky comment keep it to yourself.

Sure, relax.
The thing is, there are many potential reasons for this phenomenon, that your buddy's phone can not recognize any sim card:
1. Broken sim card, which is not likely because your buddy tried many sim cards;
2. Broken sim card slot, which is only repairable by tear down the phone and replace the slot itself;
3. Broken integrated circuit, this is hard to locate, especially if you work on a boat, the salt from the sea breeze can get into the phone and corrode the circuit, and this is not fixable;
4. Broken software, might be:
4.1. baseband firmware, which can be repaired by re-flashing the correct firmware (aka using msmtool, or fastboot commands);
4.2. android system application, if your buddy has modified or disabled some critical application, it may cause the sim card stop working too.
5. And many other possible reasons.
And you speculate that the reason is 4.1, but you're not providing more info.
Besides, it's your buddy's phone not yours, your buddy is actually the only person who knows what happened exactly before and after the glitch comes out, no one else can speak for the litigant.
So over all my suggest is, try to use msmtool to re-flash the whole system and see if it solves the problem.
If the problem is 4.1 or 4.2, your buddy's device would be repaired, and this method is way easier than typing fastboot and adb commands for beginner (many users have caused their devices to be completely bricked rather than stay dysfunctional by executing commands they know little about.).
But if msmtool can not fix it, then the problem might be in hardware (aka 1-3), it's better to try contact OnePlus after-sale warranty to have it replaced or refunded.

I reckon not suitable for India (suitable for EU) cellular profile is activated on device.
Your friend needs to activate one for India using QPST&PDC.
