USA Baseband set on European model. No operator service. Help - Nexus 5X Q&A, Help & Troubleshooting

I dont want to be accused of spamming the forums, however I want to resolve this problem as soon as possible so...
Could someone enlighten me as to what I can do to restore my phones function as a phone after I so smartly chose to set radio band to USA on my 5x, not knowing that it would be a one-way street affair. I have no phone or operator settings allowing me to change to automatic or global mode or whatever else will allow me to access my mobile network.
People have had such issues before, however, when reading forums from 2013 or whenever, the fixes for those people have not helped me out. Either they are not working or they are phone specific.
This post is just me repeating....
http://forum.xda-developers.com/nexus-5x/help/baseband-error-china-t3238867
this.
But I would really love it if someone could help me out, as I have exhausted my own limited adb, fastboot, google search, reading comprehension knowledge.
Thanks in advance smart people.

Have you tried flashing complete factory image? It should over-write all changes you have made.
If you don't want to do that, flash radio etc separately.

Thanks for showing interest in my issue.
Yes, unfortunately I have flashed all the available factory images and their separate radio components individually and together. To no avail. Also. I installed a rom to see if that might help. Nothing.
It seems that this is an issue that will need a much greater skill set and the use of ceratin tools that I am not versed with.
Qpst, Qxdm and Mztool etc.
Marko

I'd try to enable all the bands that were initially there using the bands value calculator, bear with me on the naming, I haven't seen QPST for a really long time. It would be good if you'd tell us what have you tried already and what's the current state of the phone.

[Q] New ROM Issue Help Requested

I've been reading myself silly trying to figure this out & my attempts at Searching haven't helped, probably because I'm not fluent enough to use the correct terms. In spite of having this device for several months, I've never learned as much as I'd like. Anyway . . .
I finally flashed the newest stock ROM from HTC several days ago. The process seemed to go fine with one exception: I keep getting a notification that I have a new Voicemail when I don't. I check -- no new Voicemail. I Dismiss, but the the notification keeps coming back periodically. Suggestions?
Other than that, things seemed to go smoothly, and I started slowly getting things back the way I like them. After reading & making sure I understood (or so I thought), I installed the .NET 3.5 Framework so I could use Crud Scraper to get rid of the stuff I clearly remembered using it for.
The .NET part went fine, and then I did the soft reset . . . and lost My Location on the Today screen that shows my weather. It now says I'm in Seattle, which I'm not -- I'm over a mountain range & about 350 miles east of Seattle. When I try to change the location, it doesn't find my town or anything in my area, for that matter..
The mysteriously (to me) reappearing Voicemail Notification is bad enough, but I really rely on the weather, particularly this time of year, and it's driving me crazy that I can't figure this out. Suggestions?
TIA
Did you try looking at the several threads on this ROM in the Rom Development forum? There's a fix in one of them for this problem.
For which problem? And, do you have any idea what thread?
And, yes, I did look in the thread I found (New ATT Tilt2 ROM) -- I believe I read every post before I flashed the latest ROM, even though much of it was over my head. That's where I learned that I had to install .NET 3.5 & reboot before CrudScraper would work.
I recall several people mentioning that the My Location worked flawlessly & how great it was having the location, and I read where one or two people seemed to be having the same weather problem I'm having, but I didn't see an answer. I read in one of the forums that there seems to be a bug (although not confined to the latest ROM) in certain parts of the world, and I read a thread where there seemed to by a problem with My Location in a cooked ROM that might or might not have been related to GPS not working. I read something else where My Location wouldn't work with 3G, only with Wi-Fi, so I tried that, even though My Location was working just fine after I flashed to the latest ROM -- that didn't help.
So, it's not like I'm asking because I hadn't already tried to find solutions myself. I'm not doubting that there are answers to both of my issues but rather that after spending several hours over the weekend trying to find the solutions, I've been miserably unsuccessful. Otherwise, I wouldn't have asked.

For the My Location feature, only part of the service is understood. For the most part, the location is determined by the cell towers your device connects to. It depends on where you are as well as the signal strength. Sometimes the request is not sent or received to/from the tower(s). It is more accurate usually when 3G is turned off. The alternative is to add your city manually. If the location servers can't figure out where you are, then it won't work.
Normally the stock ROMs fix this and work wonderfully after flashing. The best solution to this is to turn off 3G to get a fix or find your city manually.

I'm feeling really stupid here, but being a glutton for punishment, I'll keep trying.
Is it possible that maybe there was something wrong with the towers here that just happened to coincide with the soft reboot after installing .NET? The reason I ask is that My Location is now correct. Yay! That would be just my luck: bad timing.
Any suggestions about the incorrect Voice Mail notification? It for sure comes back each time I power up the phone. It seems to me it also reappears at other times, but I'm not positive about that -- I'm going to try to pay better attention.

Make sure to install .NET CF 3.5 to the device and not the storage card. You'll then need to restart, if it doesn't ask you to do so. You then need to force it to use 3.5 over 2.0. Use a registry editor and navigate to HKLM/Software/Microsoft/.NETCompactFramework. Change the DWORD data of entry 2.0.7045.00 from 1 to 0. Then change the DWORD data of entry 3.5.7283.00 from 0 to 1 and then reset. This disables 2.0 and enables 3.5.
For a decent registry editor that can be used from the PC side, check out CERegEditor if you don't already have an editor of choice.
For the voicemail problem, there are two known solutions. You can either have someone call and leave you a voicemail. You would then check it and delete it. You can also simply call your provider and have them reset your voicemail account. Either one should work.
If neither of those options works for/appeals to you, you can give this a shot. There are no guarantees that it won't come back after a soft reset, though. Using a Registry editor, navigate to the following keys:
HKCU\System\State\Messages\vmail\Line1\Unread
HKCU\System\State\Messages\vmail\Line2\Unread
HKCU\System\State\Messages\vmail\Total\Unread
There should be a value name "Count" with a REG_DWORD value
Change value to 0 in decimal or 00 in Hex.
It should remove voicemail notification icon from the taskbar.

Many thanks! For the Voicemail, I used method one, and it worked
And, thanks for the instructions (and the reg edit program suggestion) to force use of .NET CF 3.5 because I missed that part -- yikes.
I'm on a dedicated mission to cut down on the elecronics I have to carry around, so I need to learn more about the features of the Tilt2 because if I can just figure things out (which I've not forced myself to do), the Tilt2 will, I think, be able to replace my PDA & iPhone.
Anyway, thanks again for your help!

Softbank htc desire apn and internet

Hi everyone.
I have been looking high and low for a straight answer on this, but none exist. Softbank staff are less then helpful.
So, the situation,
HTC Desire , global unlocked, i believe from hong kong
Softbank Black Sim Card.
I am trying to get this to work and set the APN settings. Im starting to think that when connecting to their network it will detect it as a foreign phone
so, if someone knows, please share how to do the following;
1. Root phone and change settings to register as Japanese mobile
2. Setup APN
if anyone can help that would be great!!
Hey there,
I'm not too exactly sure about your first question, but I *think* I can help you with your second.
Correct me if I am wrong, but you want to set up your APN to Softbank?
If so, you should probably refer to this thread
It basically explains what you need to fill in under your APN fields.
Hope that helps
hey man thanks for the reply
that was the first site i found and doesnt work. it says the apn is configured wrong. would have been gold if it worked, but doesnt. sad....
Sorry about that :/
All is not lost though. I remember when I first got my phone, I was roaming the internet and I found this blog where this Android owner who is/was living in Japan.
Give me a few moments to see if I can find it.
At worse case, you could always contact the owner for his help on his APN settings and the sorts.
Edit: http://www.desire.giesecke.tk/ seems to be the place.
The website contains mods made by the owner on top of custom roms found on XDA. Some (or most) of his ROM mods comes with this "Softbank APN (special Desire version)". Although, if you are not too keen on flashing a ROM over what you have, you could just ask him how he did it.
I hope that helps
wow thats great! i NEED to talk to that guy.
I dont care about rooting, flashing, etc, as long as i can get this bad boy to work.
my friedn is saying it might be a little easier, all i have to do is change the strong name, which i beleive requires rooting.
i am going to try a few things this week i guess and see how we go. I am really going to try and find that one guy though and see if he can help me out in this.
I wish you all the best. Let me know how it goes

[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?
Sent from my SGH-T989 using xda premium
@#11 That reads like gibberish to me
@#12 I think I posted a fairly extensive report on how I fixed this...?

[SOLVED] Share your .qcn file ?

I've been searching, following leads, tips and suggestions all over this forum and others, yet nothing has worked so far...
While trying to read my GS3 from QPST, the little progress bar stops about 25% of the way, and I get this error:
"The phone has stopped responding to memory read/write commands"
I think the NVRAM items are incomplete or corrupt. When I dump the .qcn file it's very small: around 5K.
So, I am going to ask if anyone can share their Sprint GS3 backed up .qcn file with me to recover my device?
I realize that your phone's sensitive data resides in here. Stuff related to 1X/3G and such. My promise to you is: I will not use your data and attach my device to the Sprint network. I simply need it to get beyond my current problem, that is all. I will immediately write my own data to the device, never will your .qcn see the network from here.
Please help me. It's been literally 6 weeks since this happened and I have no other recourse.
Thanks in advance.
I'd suggest just trying to find someone you know that also has a Sprint S3. I don't think anyone will be willing to upload their file for you, especially over an online forum.
Good luck.

I hear what you are saying.
Having been a member here at XDA for 5 years now, I've seen how people help others and accomplish some really big things. I figured after all the frustration I have felt that someone reading this would help me out. Frankly, I don't even know if a clean .qcn image would solve my problem! But I have ODIN'd this thing several times, made sure modem matched the OS, performed factory resets galore, flashed modems in CWM, searched the wiki, youtube, ho-fo, new QPST version, new drivers, googled till blue in the face... you name it. I know with enough reading and enough knowledge the problem can be solved. The moderators always harp on not starting yet another thread when "the answers are all here... just READ" and tust me, my read/post ratio is easily 1000:1 but it never hurts to go ahead and ask.
The device responds well to QXDM, and perhaps my focus should be there. It's not bricked, and I found the MSL. The PRL is good, and it reports a strong signal, so it has to be something very small and very minor. Finding it is the key.
Even if someone dumped the .qcn from a factory reset GS3, prior to hands-free activation which contains no personal NV data. Would be helpful. I'm close to the solution for sure. Thanks for hearing me out.
Nv data is not cleared until you activate the device on a different line or network. No factory reset will wipe that data.
UPDATE: It turns out that DFS saved the day. Using version 4.6.4.1 I was able to view and update NVRAM values with no trouble. Note that DFS's log screen was kicking out messages such as ERROR and BAD_PARAM even though the result was parms written. It took some faith not to throw in the towel. It's possible the same kind of flying blind could have worked with QPST, it's just that DFS was a bit more intuitive.

It's likely my original assumption of corrupted NVRAM, and thus corrupt QCN was incorrect. So, I never did use DFS to update my .QCN file. Like I said, it took some faith and flying blind, but the end result was a functional GS3... Does that answer the question?

No, but I did get QPST working to find out that my modem was too updated.

VoLTE and WiFi calling

Hi
I am trying to enable VoLTE and WiFi calling on my Nexus 5x. My carrier supports these features, and as far as I know, Nexus 5x is capable of supporting them as well. My phone is rooted, and runs Pixel 2 ROM which I found on xda (https://forum.xda-developers.com/nexus-5x/development/rom-pixelmod-lg-nexus-5x-t3486862). I have Magisk flashed and I just enabled the "VoEnabler" module so that I get the necessary toggles in Settings. They appear, but unfortunately, they do not work. When I check IMS registration in ##4636## (##INFO##) it still says "Not registered". I have learnt that I need to enable a certain "profile" for the Qualcomm radio chip as well, so I downloaded QPST_2.7.460 and managed to see the phone in PDC.exe after installing the correct Qualcomm drivers on my PC, and setting the DIAG PORT to on for the phone by issuing the command 'su; setprop sys.usb.config diag,adb' in a Terminal emulator on the phone. Where I am stuck now, is in PDC, because it only shows me 3 profiles: HW_DEFAULT, SW_DEFAULT and ROW_Generic_3GPP. I read that Vodafone_India, or Telefonica UK, or Telia Finland would be profiles that may work with my carrier and allow my phone to register with IMS, but unfortunately I do not have those in the list. So, my question is, does someone have more experience with this, can I load MBN files for this profiles using the "Load" button in PDC? If so, do files coming from other Nexus 5x, or even other phones work? If anyone has any experience with this, any help would be grately appreciated.
A little update: I tried with some of the mcfg_sw.bin files from the stock ROM, unfortunately, it just cannot activate for Sub0 and switches back to ROW_Generic_3GPP. Furthermore, I downloaded an LG G4 firmware, as that phone uses the same chipset, and tried to see the files extracted from the KDZ file usig 7zip, yet none of the "mcfg_sw.bin" files actually appear in PDC so I cannot "activate" it on the phone. Would really appreciate someone with a bit of experience to guide me on this one.
Thank you very much.
PS. Sorry if this is the wrong section, feel free to move it wherever it belongs to.
Your carrier needs to have enabled these features in their network for your phone model, too.
I've found that support for VoLTE is very spotty among custom ROMs. Some don't seem to pay any attention to it, some say they "support" it but it doesn't seem to work. That may be a per-carrier issue. FWIW I'm on Verizon in the USA and CandyROM is one of the few I've found that "supports" VoLTE, *and* it actually works for me, *and* the ROM is actively maintained. So maybe try that one if you're not too attached to PixelROM. I wish this feature was paid more attention by developers, it really makes a big difference in call quality.
The carrier supports it, of course. Do you have the same phone (5x) and run CandyROM on it? Have you got a link for it? I don't see how ROMs really have to do anything special, since they do not touch the radio partition, which is still the one from stock. You just have to add the toggles to the Settings app by editing build.prop, I guess. But I will take a look anyway, maybe it actually works, although my carrier does not support this actual model, I was hoping I couod change the modem config on it and force it to work with WiFi calling and VoLTE.

Yes, I have a 5X, run this ROM, and VoLTE works.

Maybe I'll try it, although I am pretty sure it won't work by default on my carrier, since it has the same default radio which lacks the proper config for my network. That's what I am trying to get, a proper config that will work with my phone, by switching it with Qualcomm PDC.
For Verizon, the necessary config is already in the radio image, of course, and probably gets picked up automatically when the device signs into the network. For Europe, all I see is EE UK...
In the UK the operator EE does support VoLTE for many phones but not for the N5X, even if you've "provisioned" it in your ROM.
