Develop Bugs

No Connection to Carrier, please help!

Ok, so I updated my s3 to 4.1.1 but after a week of using the update, I still hadn't seen any sign of the expandable notification options. So I decided to re-install the update by flashing via Odin, which I did. After the flash, the expandable notifications still weren't available, so I instead flashed the stock firmware, hoping to update from stock and see if the problem was fixed. Unfortunately when I rebooted after the stock install, my phone would no longer connect to data, or even to the network period. I can't text, make calls, or connect to data. It shows full bars but when I try to do anything it tells me the network is unavailable.
I tried a lot of options for fixing it:
-I checked all my network settings. Data was on, I switched into and out of airplane mode, no luck.
-I tried to set my network operator by manually selecting tmobile. No luck.
-I tried re-entering T-Mobile's APN settings. No luck.
-I tried to restore from a backup I made of my 4.1.1 when it was first updated. No luck.
-I tried flashing multiple versions of stock firmware, as well as cm10. No luck.
-I checked my IMEI, it's correct.
-I flashed a few different modems. No luck.
I've run out of ideas and I can't find any other ideas in the forums. The closest I have come to getting a fix was during one instance when I was flashing stock again, I cleared my cache, dalvik cache, and did a factory reset as well as formatting my internal storage. When it did the first boot it had service for about thirty seconds. I was able to receive a few waiting text messages, and I had edge data for the remainder of the 30 second or so period. Then I lost data again. Every time I boot a notification ticks on my status bar that says "Restricted Access Changed" and before I can pull down and tap it, the notification is gone. When I try to set a Network Operator, it says something along the lines of "Unable to connect, not registered on the network." I'm stumped.
Has anybody else had this problem, and does anybody know how to fix it?

Just a guess, but perhaps T-Mobile has blocked your IMEI? Did you buy the phone off of someone or straight from T-Mobile?
Did you ever report it lost or stolen?
Only thing I can think of given your scenario.

I bought it through Costco as an authorized upgrade offer by T-Mobile. I can't imagine any reason why my IMEI would be blocked. I went to the t-mobile store yesterday and they told me that it should be working and that I should take it back to Costco and see if they can do anything for me in terms of replacement.

Problem Solved!
Apparently it was because when I got my phone they didn't give me the upgraded sim, they just cut my current one to fit the microsim slot. Go figure. This could have been solved by tmobile last night if the guy hadn't refused to help me just because I had rom manager installed on my phone. Just because I have a root program installed on my phone doesn't mean my phone got messed up playing around with root. Anyways, i updated my sim card through tmobile's phone service and I'm a happy camper now!

T999L issues

so i bought a T999l a few weeks ago had it unlocked, rooted and activated with my existing t-mobile account. For some reason my 4G never worked with them and after several calls they said because my phone was modified they couldn't help me basically. I started with some of the roms from this link http://forum.xda-developers.com/showthread.php?t=2308514 but ended up going back to stock or prob trying to go back to stock because it still says its modified in status of phone. so i was back to 4.1.2 with uvamb7 kernel. I ended up trying sim cards from different carriers and found out that 4g works with at&t sim cards. so the other day i joined aio and finally had 4glte for the first time on this phone. As the days go by though i started noticing it wasnt keeping 4g or 4g lte when i was moving around. As a matter of fact i have to force it to go 4g or lte by either restarting and getting lucky or by using *#2263# and switching sometimes several times from only lte and gsm to automatic or all lte basebands (which gives me lte but i cant make calls or receive calls apparently) and then switching to automatic. Basically if i get lucky and its getting 4glte on automatic it will be fine until i move to a area where there is no lte then its gone until i force it to go lte again even if i get into a area that has lte/4g. Its like its not automatically detecting its in a 4g/lte area, it just stays on edge until i force it. I then tried the 4.3 rom at this link http://forum.xda-developers.com/showthread.php?p=48399478. I sort of got it working but i think i might have been using the wrong kernel because whenever i restart the phone it doesnt load past the galaxy sIII splash screen. If i dont restart however it works but same issue i have to force it to detect when its in a 4g or lte area. So since that wasn't working too well i went back to the stock 4.1.2 setup. So im thinking is this an issue with my antenna or something? I'm still learning this phone so any input would be appreciated. Thanks in advance

If your had updated to stock 4.3 and if the latest version from Samsung contains KNOX in t999l variant, follow this step !
reboot into recovery mode and clear the cache and restart the phone! this should work..!

i found a t-moblile 4.3 firmware update last night and flashed it using odin. Seems like its not rooted anymore since i'm getting the stock recovery now. I assume wipe cache partition is the same thing right? so i did that and restarted the phone. 4g lte came right up. I make a call and it drops to 4g which is fine considering before it would drop all my data during a call. Here is the thing though after the call it shows full 4g for a couple seconds then no bars, nothing. No data no network and it will consistently do this . im starting to think this phone is possessed

Stop flashing stuff. Odin to stock (4.3 if you have ever flashed 4.3 via odin, 4.1.2 otherwise) and bring it in.
Also, make sure you use the right firmware, or you will hard brick. If you have never flashed 4.3 via Odin, use MB7. If you have flashed 4.3 via Odin, use MK4.
No amount of flashing random stuff will fix your nv data.

I did flash MK4 and i bought this phone off ebay. I don't have a warranty with it. Where exactly am i bringing it in to?

If you have the t999L it has warranty... Hasn't been out long enough for warranty to run out
Bring it in to your carrier (tmo?) And have them reprovision it. It sounds like bad nv data, and unless you have a good backup, the carrier is the only one that can fix that.

I have the same problem, I paid 15 dollars to the unlockpros.com to remotely unlock my T999L. they did unlock it but now 4g data in t mobile is gone, it freeces, on aTT I get 4G but it goes on and off.
I spoke to them and they tried to fix it remotely, the 4g finally appeared again on t mobile network but then after restart same problem again, no 4G data on t mobile,
does anyone has a full NV data backup that I can use to restore?
will a NV backup from another gallaxy 3 work on mines??
hope someone can help.

Don't use anyone else's nv data, major problems if they turn their phone on ever, and legal issues.
Just Odin the root66 mb7 full restore. That will put you to 100% stock, but with root. You can then use triangle a way to reset the flash counter and modified status, then bring it in to tmo. Make sure to tell them not to update you, or you are stuck with the new bootloader. They might update you anyway "for your convenience", just FYI.

Anybody ever have issues with apps? I first had an issue with the stock messages app not allowing me to send out texts to a single person. Been having this issue for about 2 months. Have been in touch with T-Mobile repeatedly and they reset the signals and everything each time to no avail. Last rep I spoke with said to bring it in to a T-Mo store and get them to change out the SIM (in case that was the issue) and get them to do a back-up & reset. That too did not help. Eventually I downloaded the Google Messaging app and through that I'm able to send out normal person to person texts again but not through the stock app.
I've also got issues with apps having updated versions yet the updates aren't available in Google Play Store for me to download. For example, on June 27th, NCP Mobile came out with version 1.8, but it's still not showing. I've been in touch with the National Consumer Panel, and they say as long as I'm running Android 4.0 or higher (actually running 4.3, rooted- stock ROM) I should see the update available.
I've also been experiencing issues with Perk apps (namely Perk Browser and Perk Search & Win) not allowing me to sign in via Facebook or with email and password. Password reset links almost never get sent. The 2 times they did finally send me a reset link it directs me to the Perk homepage also on which I cannot sign in. I'm in touch with them regarding these issues too.
The last app (as of right now) that I am experiencing problems with is CSI: Crime Scene. The app doesn't allow me to connect to facebook to play with friends like I do when I'm on facebook.

Keep losing data connection and apn setting access

I picked up a Sprint prepaid HTC 816 recently and decided to flash this rom below
[ROM][UNOFFICIAL][CM12.1][5.1.1][VirginMobileUS][A5][single sim][1/1/2016 security]
That one
It installed great, had everything everything working after I added my Sprint APN settings. The phone still displayed it as Virgin Mobile and only 3g seemed to be working. But I was making and receiving calls, text messages and had mobile data.
Fast forward a couple of hours, I installed a custom theme from the Play store, rebooted and ever since then I lost the ability to pickup a network signal and access my APN settings.
If I re-seat the sim and toggle airplane mode it will pickup a network signal and I can regain apn setting access again but it drops within minutes.
Ive reflashed the rom, wiped everything reflashed again, same thing. Any ideas on what has happened?
Thanks and appreciate your time!

Are these the APN codes you used(poster corrected a mistake in green text)? Looks like there is a different APN for prepaid /postpaid.
http://androidforums.com/threads/working-sprint-prepaid-apn-settings.920752/

I indeed use the apn settings in the green from that post. They were working fine until I had a reboot. Then everything went to ****. It wont even let me access the apn settings and when I can its briefly and then I lose signal and apn access.

I had an issue with something on my Virgin mobile 816 a5_chl a while back and a member @wxppro was very knowledgeable about APN settings and their intricacies. He had a MVNO 816 at the time with an APN issue and I bet he could help you with this as that was my best suggestion for a fix and it didn't help you.
See if you can direct him here to this forum so that if he can help out the info is here to help others as well. Good luck.

Not sure how much I can help. APN is a tricky business. If your APN settings disappear after some time, it is generally because the cellular network the phone connects to does not match the APN's MCC/MNC numbers. Or it could be the phone is in 3G mode (CDMA EvDo mode).
You can try these things:
Switch network types, from LTE to 3G, wait a minute, and then back to LTE. APNs do not show up in 3G mode. They only show up in LTE (or global) mode.
When you have the APNs show up, check the parameters are correct, you can do a "Restore to default" and then add the new one following that post.
Hope this helps.

I'm having a similar issue as well (except on virgin mobile)
A month ago I flashed squid's version of CM 13 on my phone and everything was fine for a few days, until I completely lost LTE and access to APNs. I reverted to stock and still was unable to get LTE, although I could get a shaky 3g connection if I changed the network mode to CDMA only. I called virgin mobile and they walked me through the troubleshooting steps and eventually determined it was a network outage (even though two desires in my house belonging to other family members had LTE). I called again after they verified that the network was working again and they were still unable to fix the issue.
Recently, a friend upgraded from a desire to a different phone on a different network, and gave me his old phone. I plugged in my sim card and activated this new phone and I got LTE. Figuring everything was good, I decided to flash squid's ROM once again. The same issue happened, I got LTE for a day or two until it cut out service again. No access to APNs, not even any service in stock or on the official build of CM12 with the APN fix (I can't access APNs there either). I'm out of ideas and would appreciate if anyone had any input on my issues.

I have this same phone a5_chl Virgin Mobile. Did you factory reset your device before flashing back to your stock rom? The other thing is and this is just my opinion not a statement of fact or a knock on the wonderful Bigsupersquid but that 13 CM ROM is nowhere close to being stable enough for me to risk flashing it to my daily driver phone. Just read all the posts and his candid responses. You were basically a beta tester .
I'm not an expert in APN's but if you can't get that fixed your last resort might have to be wiping your system and then flashing or running the executable RUU (rom utility upgrade) file found for our device on HTC/downloads . This is a last resort option and wiping your system will remove your existing firmware so have the correct RUU for your phone downloaded to your computer before attempting a wipe. If it's an exe, which I believe the U.S. Virgin Mobile one is ,you will hook up your phone fully charged in fastboot mode then from your computer run the exe RUU like any other exe executable program and wait. It will reformat all partitions and reinstall pure stock ROM. Hope someone else had an easier fix for your data issues and good luck.
EDIT: you will need your stock recovery flashed back and a relocked bootloader before flashing the RUU but I've read that some have flashed their RUU over a custom recovery with a locked bootloader and it wrote over the custom recovery with the stock recovery. I have never personally tried this just the first way I mentioned and that worked for me.

OK then you did get back to stock not from a nandroid backup but from flashing or running exe stock RUU? If that's the case then it replaced everything that might have been changed and your issues shouldn't be related to any APN changes.

i posted about my lte issues i had for nearly two weeks, running stock just to verify the data service problem wasn't my rom...
i had to install stock recovery, relock bootloader, download the ruu.exe from htc and extract the .img file in Wine, then rename it onto the sdcard and reboot into hboot so it'd flash. neither Wine nor virtualbox xp talk correctly to any of my phones over usb. and i wasn't about to native install Windoze.
factory reset stock didn't fix it, even trying activation, update profile, etc.
i learned i could get 3g data but switching to lte instead of cdma shut down data entirely.
virgin eventually directly escalated me to tier 2 tech support in my last call, they sent a couple service programming pushes to the phone that got my lte back online.
i tried the various service programming menu options repeatedly, with no results but the prl updated once; but the trigger to fix my lte seemed to come from upstream.
i tried various apns, in cm12, cm13, and stock lollipop. rebuilt init_a5.cpp with different mccmnc and adjusted apns. i really tried most tricks in the book plus a few more.
as far as alpha testing goes, at this point I'm just sharing something cool... i always enjoyed flashing latest greatest on my ov way before i was building.
not too many actual logs to really bug report for either rom.

Some of that was over my head but happily not all of it. Basically what your saying is the fix needs to come from the carrier and it's a reset issue on their end not a custom rom issue? By the way I'm a big fan of your work. Hell I might be on one of your older ROMs right now I've flashed so many I forget. Thanks for the education.

It does sound a lot like a carrier/account issue as I managed to kill 2 different 816s. I don't think it's the SIM card itself because I put it into a 3rd phone and got LTE, although since it was someone else's phone, I didn' t bother activating it.
I guess you got lucky with support, I tried talking to them and they tried the same thing with me. Although all I got was excuses saying they're logging a ticket with their "network engineers" and to call back in a few days. This continued on for a few weeks until they determined I needed a new phone, which I was also bounced around for another few weeks (I still don't have it).
I'm just completely lost now. I'm almost certain it's my account and it needs to be reset, but I can't get a tech who can help me. How did you manage to get someone in tier 2?

This is starting to scare me as well because I'm thinking of going back to stock once Marshmallow gets pushed to our phone to get my beats drivers back and this is making me think twice. Sorry your having so much trouble.

seemed that way.
i took radio logs before and after it worked, and worked only on 3g, and it looked to me like the sim card responded differently to the ril after things were running right again.
mine might've been a special case, though, it came from ebay with no sim, and virgin had to go to a little effort to get it programmed when i installed the sim initially.
they also claimed for several days that the local Sprint tower was down for lte service.

It does sound a lot like a carrier/account issue as I managed to kill 2 different 816s. I don't think it's the SIM card itself because I put it into a 3rd phone and got LTE, although since it was someone else's phone, I didn' t bother activating it.
I guess you got lucky with support, I tried talking to them and they tried the same thing with me. Although all I got was excuses saying they're logging a ticket with their "network engineers" and to call back in a few days. This continued on for a few weeks until they determined I needed a new phone, which I was also bounced around for another few weeks (I still don't have it).
I'm just completely lost now. I'm almost certain it's my account and it needs to be reset, but I can't get a tech who can help me. How did you manage to get someone in tier 2?

tier 2 takes luck, time, many calls, and eventually you learn the answers to all the questions tier 1 outsourced from India asks so you can feed it to them so fast they want to shuffle you along. takes a couple of weeks to over a month to get to tier 2 and sometimes they have to be involved multiple times as well.
I've been dealing with virgin since 2009... replaced only two phones, eventually got the rest of the issues hammered out with persistence.
for a little while, twice, i had direct toll free numbers to American tier two even because my issues were so hard to solve. it didn't take too long for those numbers to be disconnected, though.

Signal problems after root, twrp and reflash

I'm having an issue with connectivity, please help if able.
1. used CF auto root method from this link https://forum.xda-developers.com/sp...uide-links-files-update-root-restore-t3366862 when I went to TWRP it would say recovery is not seandroid enforcing, but would go on to TWRP anyway.
2. made backups
3. connectivity problems started. could make and receive phone calls in certain places. dropped phone calls and went straight to roaming with unstable connection.
4. reflashed stock firmware from Koop1955's post
5. noticed I still had connectivity issues even when back to stock
6. reflashed twrp and root
7. still have connectivity issues
8. not able to activate through hands free activation or dialer codes.
9. can see sprint then it goes away. will get LTE in other places
10. Any ideas or direction to how I can start to affirmatively diagnose issues?

@Saafir, I have been trying to help, but I am out of ideas. Any suggestions for him?

Tried dialer code

I tried that dialer code on it, it goes to SCRTN then reboots and goes to Hands Free Activiation where it fails all times.

Thanks

Providing you have your MSL # do the ##data# menu, and make sure you have all of the LTE bands enabled. Carrier aggregation too. Other than that not sure what to recommend besides a trip to a Sprint store.

I have MSL code and looked at ##data#. All bands are enabled on the LTE front. Would placing a new SIM card work? or should I try going through more advanced diagnostics? The phone works and makes and recieves calls as long as i'm not in a bad spot. The thing is, there are ALOT more bad spots and it shoots me to roaming in the same area my fiancee has LTE and good reception. Same phone, same service. Any way this information can help?

One more thing

I had to get the phone repaired about a month ago. They placed a new daughter board completely on it. Could this affect it after flash? I had no problems with reception before root and twrp so I didnt think this would be relevant but maybe you guys know how to check if that is where this issue is coming from.

Doing a wipe via TWRP and then flashing the TAR should return the phone to stock state. Since the problem happens when you are unrooted and back to stock recovery (as well as when you are rooted and running TWRP) it seems likely that it is hardware. If I were you, I would do another wipe (System, Data and caches) then Odin the latest TAR and bring the phone back to where the repair was done. Tell them that you took the latest OTA update and the phone failed and that they need to fix it.

Verizon HTC 10 will no longer work on Verizon after flashing

I flashed the the newest firmware, then flashed the Pefume 2.51.617.32 rom, and now the cell portion will not work. It will pick up a signal if I reboot, or sometimes toggle airplane mode. It will show 4g, but then it just goes back to the line over the bars. The sim card works in a Verizon iPhone, but if I manually try to connect to Verizon I get your sim card doesn't support this network error.
I assume I don't need to reflash the modem since I do get a signal after a reboot for about 30 seconds, then it goes away. I also have tried a factory reset, network reset, and verified my imei was still on the phone. I got this phone used with s off and unlocked bootloader already. It was running stock Android for Verizon 7.0. Firware was 2.41 before I updated it to flash the newer rom.
Any suggestions?

I reflashed the modem a couple times, and it is now working. However, wifi calling doesn't show as an option.

Did it work before you flashed it?
Is the SIM locked to your iPhone?
Do you have a network update option? Does the network need time to recognize the new phone? (I haven't used CDMA in years, don't remember beyond it being a pain)

There is a thread similar to this in the Verizon forums.
https://forum.xda-developers.com/verizon-htc-10/how-to/vzw-how-to-unlocked-model-vzw-t3376743/page40
Might not be so easy to get working. Since you're on the verizon network I would just convert it back to VZW software. The Oreo update is supposedly coming soon, and that way you wouldn't have to mess around flashing radios, etc.

I flashed all the way back to 1.85 Verizon RUU, and had to run the erase modem fastboot commands to get wifi calling back. I then flashed Twrp and the newest custom rom based on 2.617 and wifi calling is still in place! However, I lost my home button. I quickly figured out the firmware was still on 1.85 from the flash down to 1.85, so I flashed the newest firmware to match the rom and everything is back working.
