[Q] T-989 - No data network. Mobile Network State: Disconnected

Hi there. I own an unlocked, rooted t 989 Samsung Galaxy SII which I bought in the US. I recently moved to the Netherlands, and got a new simcard with Vodafone. The problem: I can't get my data to work.
I have tried (almost) everything, so prepare for a read. Here's the list:
- Sim card is fine, I tried it in a old phone and 3G pops up instantly
- Rebooted, pulled battery, turned mobile connections on/off, handpicked network, etc, etc, all the basics.
- Got the APN settings from Vodafone. Tried them manually, resetted them, automatically, turned it on, turned it off.
- Going online through Wifi works.
- Under settings-Status it reads under Mobile Network State: Disconnected. But I know that the phone detects the network correctly. It can distinguish between UMTS and GPRS here.
- So there seems to be no trouble with the phone being incompatible with the network. I read online that other people had NO trouble using their T989 in Europe.
- I tried inserting my old American pre paid T mobile sim card and turn roaming on. No luck.
- A lot of other people with the same problem tried to link it to Easy Battery Saver. I tried updating, uninstalling and going into its settings to find out what it could be, but nothing.
The last thing I can still try is to factory reset, unroot and try to get the phone to its most original state and see what it does. But before I triple wipe all my contacts, pictures, apps, etc, I want to make sure I did absolutely everything to try and fix this beforehand. Being a noob here, I can't post any links but I trust you I tried.
The people at Vodafone are of no help whatsoever. I hope you geniuses could help me any further.
[Edit] And sorry for posting this in General Chat. If a mod could move my question to Q&A I'd be most thankful..!

I am having the exact same damn problem! it started with being unable to send a simple text message yet having data. now it says it is searching forever

Try flashing a different radio/modem then an american one?

@decko5 Nice to see I'm not the only one, but that doesn't help us yet .
@doug36 Besides the fact that I'm running a stock ROM that should be compatible with no issues, I'm not sure how I'd do that. I can flash a separate part of the kernel? That sounds like a very tricky thing to do.

It's actually pretty easy. You can flash most radios via ClockworkMod Recovery. I couldn't find any threads with a list of Galaxy S-II radios here on XDA, but I found one over at RootzWiki for you. http://rootzwiki.com/topic/2725-radio-samsung-galaxy-s-ii-radios-updatezip-updated-20-aug-2011/
Just find the corresponding one to your geographical location and carrier (Google is your friend) and follow the steps.
Good luck and hope it helps!
(p.s. you should definitely look to see which radio you currently have so that you can download a backup of it before you go flashing radios.)

Thanks for that very helpful post! I've raped and butchered Google, but I'm still having trouble finding out which modem I should download. There seem to be so many and the post on RootzWiki gives no guidance to which is which. Any wisdom on this? I'm in the Netherlands, so Western Europe, on a Vodafone network.
By the way. I fully wiped my phone and installed Team Kang's Juggernaut 5.. No luck, same problem. What I found really, really weird is that it was instantly in Dutch. (Which is ok, I speak Dutch) But I don't remember ever selecting a language. How does it know? Besides, I'd rather have it in English .
What I did find out is that I'm still using a old firmware, UVKID, instead of UVKL1. So I'm restoring back to my previous ROM and trying to update. I'll see what happens. If that doesn't work, I'm going to restore my phone to stockest of the unrooted stocks and try and update.
If that doesn't work, I'll have no option but to send the phone to T-mobile.
I'll try the modem update as soon as I understand what I'm doing . But it does sound promising. Thank you so much for your help, it's greatly appreciated!

Hi guys,
I've updated my firmware to UVKL1, still no luck. Anybody who can tell me which radio I should try on this Vodafone network in the Netherlands?

I am from India and had faced this similer issue with many of my android phones specially with captivate and infuse.......Here what i always did to connect data network.
Just uncheck the use packet data network box in mobile network settings and try to move out from that area (say u are in ur office and going back home) and check the data in settings.
This thing has worked for me always, I don't knw if its related to the OS or to the network provider but this has helped.
Have u tried any other network sim card on ur phone ?

An update for other people that might be looking for a solution in the future. It turns out to be a clear Vodafone problem. I tried a different simcard from a different network (both T-mobile Netherlands and KPN), and they instantly worked without any trouble.
I went back to a different Vodafone store in Amsterdam, and they were much more helpful than the first one. The sales guy told me he had seen the same problem with AT&T iPhones on the Vodafone network.
I called Vodafone, and they have been very nice to me. But they haven't found a solution yet and are looking into it. They see me registering to the network, granting me access, but still my data doesn't work. They've also told me that they will let me cancel my contract for no cost if they don't find a solution.
So problem remains unsolved, but at least there's some light at the end of the tunnel. I was close to buying a new 500 dollar phone... Americans going to Europe: Beware with getting a Vodafone simcard. Sorry to the Vodafone guys, but as for now, that's the status.

So to give closure to this issue (I always hate it when people fix their problem without telling the interwebs..)
IT WORKS!
After an initial terrible experience at the Vodafone counter, the headquarter tech guys have really been great to me. So it is indeed a Vodafone problem. American phones always give them a headache. They don't know what causes the problem exactly, but they do have a fix. It turns out that when logging on to the data network, American phones (AT&T iPhones, my T989 SGsII, and some other Android devices) sent some gibberish along that make the Vodafone server go cuckoo.
The solution was, miraculously, to sign me up (for free!) to the WiFi hotspot service that Vodafone provides, and then logging on to a different APN, being: office.vodafone.nl in my case.
Hope this helps anyone who's having similar issues.

ok the issue here is that some of the t989 are vodafone and some are USA network , now the other solution is that you flash with command prompt which there is a link to that tool im going to upload from the link i got it from . its also a clockrecoverymod , but this 1 asks you for deleting data user on the device and also resets the network includes USA/overseas though if your not customed roms
or any hacked roms , after flashing this device your basically removing any unwanted apps and cache that are hidden during network searching will be fixed bugs , put the simcard in slot but make sure that is a 3G/4G accounts, than its going to reboot the device automatically , it should be searching for service and also will be a circle with a slash on it where the service bar usually is , just wait about 1/2 hour to an hour maximum time let it do its thing , ok whats happening now to the phone is that is thinking with android network with usa and overseas market apps comparing both carriers network also gets the proper address for the custom rom or original kernel, froyo either 1 will get the correct network address and / VPN / and also will be adding both T-mobile/AT&T choose T-mobile dont go for AT&T cause it will research network configuration plus the phone its not unlocked for both its just a network passby to get correct WPN/VPN/clockworkrecoverymod .

Where is an fix?

Free (for now) CDMA Flasher Software

Taken from slickdeals.com If the mods wish to move this to the proper forum so be it. I noticed our "SPRINT" phone was supported to flash to Metro. Also if the .exe file is no longer downloadable let me know... works for other phones also....Thanks
Sprint Samsung SPH-D710 (Epic Touch SGS2) Full and Half
Free (for now) CDMA Flasher Software
This is a software program that dealers pay a monthly fee to flash CDMA phones to Page Plus, Cricket, and MetroPCS among other services. Right now they are letting people download the software for free. They have also posted a public username and password so everybody has full access to the program. As their goal is to sell a monthly subscription to the software, I would not expect this public account to last long.
Program is good in that it is free if your phone and your designated carrier is among the supported. Process is also simple in that you just input some numbers and click the PROVISION button. Not so good is that some phones do not have flashing directions at all. Maybe a similar model's directions would work??? Also although data might work with a Full Flash, it may not be 3g.
Looks like the typical way a phone is flashed is by first putting it in USB debugging mode and then dialing ##3424#. You also need to enter your phone number, MID, and SID (for you locale).
Software:
http://www.cdmaflasher.com/Downloads/index.php
1. Install CDMA Flasher
2. Install driver if needed
3. Install .Net Framework if not already on your computer
Public Account from their homepage cdmaflasher.com
Username: CDMAFLASHER
Password: test
If somebody knows of specific instructions to a particular phone with no directions within the software program, feel free to post it here.

so have you used this for yourself?

No i havent since i'm locked in for another year. I just may have to thou next year.

I took a peek at it, looks like a quick way to flash your phone over to one of the MVNO networks from the main networks, e.g. From Sprint to Cricket or USCell to MetroPCS (but not vice-versa)
Looks like the application is a mostly cloud-based backend, where you log-in to use the application, and then it will pull ODIN libs and device images from their servers temporarily to your PC for flashing a device over to the desired networks. the interface has dynamic menus to make it easy to figure out what's available, the D710 being one of them.
asks for destination carrier, then current carrier, device manufacturer, device model, and whether you want a full or half-flash ( what's a half flash? like i could install a cricket config next to my sprint config?)
Might be cool if I was thinking about doing that right now, but I doubt I'd really decide to make that change while this thing is still free to use. If half-flash would leave me with a simplified option to chose to use cricket at any time later if i wanted to, might be of interest...)

Oh wow. O. If still up when data renews jan 6th will doanload

Flasher Software
Thanks for the thread.
I have been trying to flash a generic Samsung SCH-i500 to ntelos for about a month and was able to get phone and text to work but no data.
I had tried everything with no luck until this.
Worked great and saved me from paying ntelos fees especially when they said they would not guarantee 3g
Thanks again

Call me skeptical and old fashioned, but... I personally can't fathom how someone can charge a monthly subscription for something like this.
From what I have read, the half flash involves giving the phone in question talk and text capabilities (read: this thing ONLY slaps in the MDN and MIN, maybe even going as far as pushing the PRL for the carrier). Full flash, unless I missed something, will likely include the half flash plus adding proxy and port settings for MMS and internet. The fact that they "cannot guarantee that 3G will work" is a dead give away of this and that the service is a scam, and here is why:
* Provisioning your device (which is all this thing does) is only a tiny piece of the whole flashing process, and a simple one to do for that matter. You don't need a PC for this (any phone can be provisioned from itself if you know the MSL number which you can either find out through terminal emulator, MSL reader apps, or even by calling your current carrier), let alone a software package with a monthly fee. The biggest hurdle is to get the device added to the carrier's db of approved phones. This is done by adding the device's MEID and pESN onto their db via things like Houdini (this is for MetroPCS, not sure about what others use as more often than not, they will not allow you to BYOP anyways);
* They cannot guarantee the 3G for a very simple reason... this does not modify/touch (likely depending on the device, of course) the HA and AAA keys needed for the 3G to be validated by the carrier's system. Much like MEID and pESN, these keys are device specific, which means that if they are not accepted by the system, you will never get a 3G connection, period.
The only 2 ways to avoid having to pay the fees for BYOP are to:
1. Have someone you know working for a corporate store add the device to their network for free;
2. Go the "illegal" route, which I am not about to describe/discuss here.
Stay away from this program, and please.... whatever you do... DO NOT pay them a monthly fee. The program will add the numbers as it describes, but please... everything this program does can be done manually through the phone itself. But most importantly, you will still need to get the device added to your carrier by paying them.

Worked For Me
My only response is the program worked for me in getting the i500 to have data and 3g. Granted I did not need it for voice or text however Ntelos told me they could not guarantee the phone would have data and I did not want to spend the bucks for them to try and fail and it still come out of my wallet.
I will say their apk for getting MMS to work did not work on my phone, but I can live with that.
For a free trial it worked for me. Most of the time all that is needed to flash a phone is the proper software.

Actually the half flash is free for everyone. You are only charged for full flashes. The monthly subscription gives you unlimited full flashes and includes the iPhone, and there is no required subscription or contract.

Don't worry, it's nothing you can't find anywhere else.
The people who were saying that this does nothing worth paying for are correct too.
What is worth paying for is a way around needing the secret keys, HA and AAA, which are required if you want to get on a different network. A Verizon 3g phone does not need to be flashed for it to run on Page Plus, but a Sprint phone does. It's a wooly world of scammers out there, except for certain ones.
Those that work offer a guarantee.

need help
can i flash my maximus max906 with this software. its android version 2.3.6 . and kernel version 2.6.3 .

Doen't work
I downloaded it using the posted log in name and password but would not activate.

For those with Cricket
I did the half flash, activated over the phone by calling cricket and switching my device. And then got the 3g working by following the steps at.

If you know what you are doing with the tools such as CDMA workshop and others, it makes no difference which carrier you flash to.

AT&T On DI2

I'm trying to figure out how to get my rooted Droid Incredible 2 (with CM9 ROM) working with AT&T. I live in the U.S. and don't really care which band I use (Don't Need 4G). What are the steps I need to do to make it work, if possible?

You'd have to flash back to a stock rom then call Verizon and ask for an unlock code for your inc2 and just say that your letting a friend borrow it and there going out of country and it should take 1 to 3 days for them to email it to you, then insert your at&t sim card and a locked sim card message should pop up telling you to inter the unlock code then type in the code and bam your done
Sent from my SCH-I535 using xda premium

Yes, unlocked DI2 does work on dometic AT&T or T-Mobile sim card for voice/SMS and 2G/Edge for data access (plus WiFi, of course)
AFAIK, they do not email the unlock code - unless they changed the procedures lately ... If you are already on a custom Sense DI2 rom, you should be okay and have no need to flash/unroot back to stock Rom just to do this - photos attached were saved while running SkyRaider's Zeus rom and Nit's Sense v5.0 rom, both of them worked flawlessly on GSM bands using prepaid Sims. The last one was snapped inside Starbucks in old San Juan using WiFi as signal wasn't great inside in extended roaming.
As VZW customer in good standing & account balances paid up-to-date, call from a land/secondary line & speak to Global Support (smartphone) tech staff (leave the DI2 up & running, battery charged & a spare/working Sim card on hand) and explain your need, they will verify your identity and once done - proceed to help & walk you thru the steps to unlock the device immediately - take 10 to 15 minutes including hold time as they search & retrieve the unlock code in their database. Did this awhile ago, vacationing down in the Caribbeans and need to use local Sim for calling and they will "caution" you about not able to provide tech support and customer being fully responsible for charges incurred, etc. with a sales pitch about various global/roaming options, etc. ... (Urrrr .... okay, understood, but let's just go ahead & help get it unlocked ... allright, please hold while ...)
You will be instructed to power down & reboot the device, and input short codes to access the special/unlock menu and carefully input the unique code, hit "Enter" and watch for the screen display for a successful unlocking. Then, power cycle it and check/test it for a successful dialing with your own Sim card and be done with.

They told me they had to hand it off to there "global" department and it took them 2 days to email it to me.

So the recent laws against unlocking don't have an effect for existing customers? I'll raise hell if they refuse to hand over the unlock code before I move to Lesotho.
Also, if I understand everyone correctly, they only hand over the codes for customers who got the phone from verizon? What if I picked up a 2nd Inc2 on ebay? They wouldn't hand over the code?

LG G2 Sprint to Net 10 not working.... almost there...what am I missing????

Hello,
First, let me express my deepest thanks in advance for those of you who may be of assistance. I have visited this site many times over the years when I needed to find the answers to smartphone related issues (mostly rooting..etc). I have usually found the information that I needed via reading posts and trial and error; however, I am having a problem that I cannot find the answer to and it is frustrating the crap out of me.
So, here goes:
I bought a LG LS980 off of Ebay. It was locked to Sprint and I had a friend of mine root it (since I couldn't figure it out and it ended up being that the firmware had to be downgraded since a patch was bumped to it) and unlocked (or so i was told, but I do not know how to find out). It is currently running Cyanogenmod 12.1. I wanted to use my old phone's SIM and pop it into my new phone so that I could enjoy it (the old phone was a Nexus and ran hella slow). So, anyway.... I contacted NET10 customer support since that is my carrier and explained what I wanted to do. They let me know that as long as it is unlocked that I would be able to just swap the SIM into the new phone and should be good to go. They checked my IMEI and said that the phone was, indeed, compatible and as long as it is unlocked it should just be a matter of a simple ROM swap. Not the case. I put the SIM in and booted it up. It went from No Service to saying "Sprint" on the upper left hand corner. I try to make a call and it states that, "The code or number that I am dialing is incorrect, please try the code or number again". I looked this up on the internet and didn't find a focused answer. I talked to my friend and he stated that I may have to set up a new APN profile.
I have checked the APN settings on it and all of the APN profiles have the prefix "Verizon". I used this mini tutorial at http://forums.androidcentral.com/goo...-settings.html along with the NET10 settings to try and make a profile. Both of their workarounds don't seem to work. I can enter about half of the information and then either click BACK or SAVE and then the profile is gone. I am not sure this is the reason that my phone is not working, but I thought I would give it a try. I have also tried to use this tutorial: http://forum.xda-developers.com/show....php?t=2798566 as a loose guide, TWRP installed. Keep in mind that I believe that my firmware was rolled back to ZVE. and not ZVD. When I have tried to edit the build.prop values at the tutorial states it does not save. Also, there are two lines that are not even in my build.prop (ro.build.target_operator and persist.service.crash.enable). When I have tried to edit or add it adds them but does not save and definitely does not persist through reboot. I feel as if I am close to getting the phone to work, but I am unsure where to go from here. I really do NOT want to have to go back to a stock ROM and all of that because....well.... my friend did the rooting and installing of cyanogenmod and I don't want to risk undoing all of his work and having to pay $ to have it done all over again (I have rooted phones..etc, but this G2 was a MOFO because of the firmware patch for me). NET10 CS and TS was of no help and they gave me a ticket number (and to tell you the truth the are outsourced and I can't understand what their reps are saying). So, does anyone have any advice or threads that I can look at? Like I said, I feel as if it is close, but no matter what number I call it says that recording. I get no incoming calls (although it rings when listening to the incoming calling phone's speaker). I am also unable to send or receive SMS or MMS messages. Any help would be greatly appreciated. I am not the most technically savvy person, but I can answer your questions to the best of my ability and I am good at following directions. (I have about 5-6 phone root/ROMS under my belt and even 2-3 SPRINT to NET10 activations, but this one is just perplexing the crap out of me) . Could it be that the phone is not unlocked???? How do I check this??? Is there a way??? When I put in the NET10 SIM it never asked me for an unlock code so I am assuming that my friend unlocked it? I have also tried "Turn the phone ON and type 2945#801# If nothing happens, type 2945#802# or 2945#*803#" and no hidden menu appears asking for an unlock code.

You can unlock your Sprint phone for GSM but you can't activate it to Verizon or its MVNOs.

Volte not working :(

Xperia XA2 H3113 Android 9 (50.2.A.3.77)
Hi,
I recently got an Xperia XA2 and I can't use VOLTE.
My previous phone the Samsung j5 pro worked, but the XA2 keeps dropping down to H+.
I have contacted Vodafone in Brisbane Australia and they say it is an issue with the handset and it may need an update.
Any help would be appreciated.
I tried *#*#4636#*#* , but VOLTE provisioned is greyed out and off.

Same problem here for over a year. *#*#4636#*#* dimmed out. Also see wifi calling under that is also dimmed out. Sometimes I spend a few days or a couple weeks trying to solve this with AT&T and a little bit with Sony. But then I have to get back to work eventually without an answer. No one seems to have an answer. Did you ever resolve this?
Sony support has informed me they have XA2 customers with VoLTE working on AT&T, and here is more confirmation it should work from Freedom Mobile.
Freedom Mobile VoLTE enabled on Sony Xperia XA2, XA2 Ultra, XZ2
Freedom Mobile's fledgling VoLTE service now supports the Sony Xperia XA2, Xperia XA2 Ultra and Xperia XZ2.

Hey @MatthewIsLost.
I'm not sure if you still have your XA2 like I do. I'm busy and just kept using it. I'm being forced to do something finally because my carrier is shutting down 3G and they think I have a 3G phone because it keeps switching to 3G for voice calls for months or maybe a year and a half. When I first bought the phone the switches in the OS were there for VoLTE and WiFi-calling, but I didn't know what they were and was busy. When I would work on my H or H+ calls problem every few months with AT&T I learned I wanted those features. Never could get it. Sony was patiently helpful over the last couple years about this and advised they would not update the phone OTA with an update that would take away any features of the phone such as VoLTE and WiFi-calling. They also gave me the URL last week that shows the XA2 as a Sony phone with VoLTE at this link...

With this recent push from AT&T to get a 4G phone, I finally decided it's time to figure this out. I spent some hours with tech support at AT&T and finally one rep listened to my symptoms and ran tests for about 45 minutes and finally asked me if my phone said AT&T at the top. It did not. That led to me finally spend more hours figuring out how to flash my Sony. Hadn't flashed with fastboot and adb since my old MotoX. Dialing *#*#4636#*#* has also shown dimmed out buttons like yours. No one could tell me what that meant. By the way, I stopped by Verizon store and they were very helpful and put in a Verizon SIM they had lying around and my phone booted with it and my screen said Verizon at the top left as it was supposed to. That was done with the flash of LineageOS ROM on my phone.
A few days ago I used the installation instructions at LineageOS to put LineageOS 18.1 on my XA2, so right now I'm running Android 11 (LineageOS 18.1) and have been testing it for a few days. Getting a new SIM I hope soon, and also hope to get a cleaner flash of LineageOS before that SIM. I still have trouble with my signal strength icon and it still doesn't say AT&T in the top left of my screen, but it now says AT&T in the settings menu next to signal strength icon. I also now have the VoLTE switch in Settings/Network/Mobile Network where it should be, and WiFi-calling switch is in the Phone app settings under calls where it should be, and they are also showing as all turned on now in *#*#4636#*#* menu. So it is real progress on learning something. Not sure what yet. Since I flashed, it doesn't switch to H or H+ any more on calls, but whenever I make a call it switches from LTE to 4G, so I'm still not allowed VoLTE for some reason.
Malware? With LineageOS, I also installed Protectstar's Anti Spy and it identifies "Data Transfer Tool" as malware and that the program's source is unknown. I cannot delete it. Search reveals a regular Data Transfer Tool is a Google app. So could this be a fake version of the real Google app, or a false positive? No idea. Maybe if Data Transfer Tool really is malware or is fake version of the real app that adds reporting capabiliy, could it be such a good fake that Google won't let me delete that part of the OS. I also accidentally found 1 app had permission to use Unrestricted Data and it was Google Play services. I don't know if it is supposed to, but I turned it off. The thinking on my part is it would fit in with how my phone behaves. It's like there is never too much damage, it has mostly been like someone is in the way hampering me and getting all my data. Makes it difficult to grow a business over years.
Also after this new Lineage flash, I noticed at boot up, even though I always keep location turned off, the little tear drop icon indicating "location on" would show up at the top of my screen for 1-2 seconds as though reporting my location. As I drove around town and tried to keep tabs on my signal I would see the location being turned on and off again and again from time to time. Since I reported this over email and voice calls, it seems to have stopped. Since I don't know much, I still think there is malware. I learned some time back there is SIM malware. SIMs have microprocessors too. Check out this...

I hope to have a cleaner flash of my XA2 today or tomorrow and a new SIM soon to get my phone to say AT&T at the top. We'll see.
If anyone knows where I can read about securely overwriting my phone storage without losing the ability to flash a new ROM, it would be great to hear from you. I thought I remembered using TWRP years ago with an option to format and it took a long time for a 32 GB phone as it should. But I wasn't able yet to confirm on the Net that TWRP overwrites all partitions. I see the "fastboot format" but something I read made me think it was only for the user data. I have lots to read.

Update July 31, 2021: My posts will continue about this problem at my URL wigglemylegs.com. I am continuing to look for technical answer for how AT&T can say my phone is 3G when they have seen my phone talking to them live on 4G, using LineageOS 18.1. If anyone knows how to straighten this mess out with AT&T it would be great to hear from you. They are trying to force my 4G LTE phone off their system by February 2022, by claiming it is only a 3G phone.

Xperia XA2 H3113 Android 9 (50.2.A.3.77)
Hi,
I recently got an Xperia XA2 and I can't use VOLTE.
My previous phone the Samsung j5 pro worked, but the XA2 keeps dropping down to H+.
I have contacted Vodafone in Brisbane Australia and they say it is an issue with the handset and it may need an update.
Any help would be appreciated.

AT&T (and I presume it's MVNOs) is not just instituting a VoLTE only policy, they are instituting a device whitelist. So even if your phone is VoLTE capable and can use this technology on say T-Mobile, if it isn't on the AT&T whitelist, it is banned from their network. So aside from the "we must redeploy bandwidth" reason, AT&T is using this change as an excuse to strike down BYOD and presumably boost handset sales...as well as the monetization of their customers by giving them handsets with preinstalled software that can more easily harvest their information.

Hey,
I just sumbled upon this threat because I'm trying to get VoLTE working on my mothers XA2 Ultra. Old_Mil is right with what he said but there is some Qualcomm tool to import the setting for a carrier to the modem. I did it for my old OP 3. But it's probably very risky to brick the modem.
If you really want I'll look for the link and some BG info.

Pretty interesting. I found this bit here below.
How to enable VoLTE on Qualcomm devices running Generic System Images (GSIs)
The VoLTE-Fix mod can be used to bring back support for Voice over LTE on most Project Treble-compliant Qualcomm devices running Generic System Images.

I guess that's what you're referring to above.

Does it work for anybody?

I've been so busy I haven't looked into any of that fix for myself. Anyone else have anything?
I spent many hours over years trying to familiarize myself with the technology involved on my XA2 and learn how to fix my phone with AT&T's help. They didn't want to help. They tortured me for years by removing my VoLTE after the first 2 months, by reclassifying my XA2 as 3G so their towers won't accept me. You can read about it at my handyman URL of
wigglemylegs.com
where I posted many details. If you scroll to the bottom of long thread you see a dateline summary. AT&T HQ told me they could see my phone was erroneously classified as 3G in their tables and they could see that it was clearly a 4G LTE phone, but they didn't have the resources to fix it. When I opened a complaint with the FCC they wrote a reply denying this. Their legal out when faced with getting caught up in corruption is to offer a free phone. They offered me several models of free phones, but I didn't want it, because it is the principle of the thing that is wrong. I currently am on Lineage OS (Android 11) using voice apps that use data only like Whatsapp and so forth. Works great. Limited on calling regular numbers, so use others for that. The HD voice quality is just super!!
May the VoLTE be with you!!
