[Q] [VERIZON] Repaired IMEI, Updated with OTA, Phone keeps roaming... - G3 Q&A, Help & Troubleshooting

Really not sure what to do here, and I'm starting to get very frustrated, especially since I know exactly what the issue is and I can't find a solution... So here is everything I did up to this point in detail. I wanted to go back to stock for a while, but I remembered not being able to update at all last time I tried this. I used the LG Flash Tool to go back to 10b (I think? Earliest firmware out there) It started when my phone would tell me that "My Device was not registered yet" in the System Update settings. I did some Googling and found out it was because my IMEI number was blanked out (All zeroes), and I found a tutorial that was for the G2, but worked for the G3, to repair the IMEI. I first rooted with the LG One Click Root Tool when I got to Lollipop, used the IMEI that was under my battery, converted it to HEX and injected it into my phone with RF_NV_Manager, which was installed with QPST by Quallcom. After doing this, my IMEI was fixed, it matched the same IMEI that was under the battery on my phone, though I never texted or called anyone from there so I never noticed anything strange. I was able to update to the latest official Lollipop firmware, but then my phone started telling me I left the home network. Thinking it was just a glitch or something, because I had roaming issues before on stock, I switched to a custom ROM since that fixed it last time before I even knew that IMEI's existed. That didn't fix it at all. I was on LiquidSmooth Alpha and my phone will still go to roaming, and the way I would fix it was to piss around with the mobile network settings and change them back, then I would get 4G LTE for a few minutes, but I would NEVER be able to call or text. Since it was a discontinued ROM, I thought I just got unlucky, so I went to an official Nightly for CM12.1. At the moment I have LTE but no calling or texting... Then I found out that these issues tend to occur after IMEI fixes, so what do I do? Can anyone point me to a proper tutorial on how to fix this? After looking, I ended up downloading and installing something called EFS Professional 2.1 but now I'm even more confused...
EDIT: I tried going into ADB and inputting "adb reboot nvrestore" but that didn't fix it... The site said it's based on a backup that was automatically created when the phone was first built but that was on a completely different forum for a different phone. Going to try to flash back to stock KitKat.
EDIT: Alrighty! I'm getting somewhere! I flashed back to 10B with the Upgrade DL option, before I used Board DL. I can call and text now, as well as LTE, and OTA updates work, but I'm just going to root and go straight to the Nightly CM12.1 that I wanted to go to in the first place.
EDIT3: That seems to have done the trick. For people who have had issues with roaming after IMEI repairs, try flashing your stock TOT with the Upgrade DL option, then root and install your preferred ROM.

[Q] Band Handover/voice network issues

So I have been waiting patiently for the 4.3 update to roll out to me OTA with hopes that it would fix my issues but my phone has been saying download interrupted and so I have gone back to completely stock and triangle away to get my device status back to normal but it still wont let me download. When looking around for other possible causes I saw that my build number is JRO03L.I747UCDLK3 which comes up as a build number for a nexus 7, the correct build number for my att should be JRO03C. I have no idea how it got that way but I am wondering if the person who bricked it might have put the wrong version of the bootloader or some other part of the firmware on and it somehow didn't brick but is detecting a conflict and not letting me OTA. Or that is what is causing my cell network issues as well. Wanting input from a a few devs as I am not 100% sure what the first part of the build number represents.
Ok guys and girl, I am having a really weird issue with my Att Gs3 that I wanted to see if anyone could help with. To start off a little bit of background. I Hard bricked my s3 in August, sent it for tag and got it back working and stock with no issues. All I did was root the phone for fear of messing it up again but it was running all stock without problems for over a month since the unbrick. About 3 weeks ago I went out of town within the state but a ways away, I was talking on the phone with a co-worker right before leaving town. At some point that evening I get a a text from my wife asking why I was ignoring her calls, I had never received them and according to my phone was in the middle of prime 4g lte zone in San Antonio but I was apparently only receiving that lte signal and the phone was not switching to the voice network on 4g to make or receive calls, I was even able to voice chat with my wife but I couldn't just call her normally. After returning home I was still unable to make or receive calls unless it was right after a restart and I had to try about 15 times, so I called att and tried all of their bs which didn't make a difference at all. Looking around on the internet I found the number that you can put in to get into service mode and switched it to gsm or wcdma only and voila I could make calls again. The only problem with that being that I travel within a city for work and move from 4g to 3g to edge all the time but if I have it set for wcdma only then I have no signal and have to take the time to pull up service mode to switch back and forth. So I tried going back to completely stock again by resetting/ formatting all and flashing the stock rom via odin, my issue persisted so I also decided to flash synergy rom (which I was running prior to the hard brick) and then intergalactic because I saw the fewest problems with it to no avail. I have flashed each stock modem new and old which made no difference at all. Today I was messing around in service mode and found an area that was called handover, in that subsection you have the option for checking the phones ability to switch from gsm to wcdma and back as well as to hspa, when I select any of those options I get the message "temporary block due to build e" or " temporary block code".
I was wondering if anyone has any ideas about what the possible problem could be, imei, modem hardware, or a stubborn stuck modem firmware setting.
I was also wondering if anyone had any experience with figuring out how to re-enable handover because that is where I feel my problem is, either through adb or any programs that let me force change the settings, I would also be happy if someone knew how to turn of only LTE and have both gsm and wcdma on at the same time.
Any help would be much appreciated, I have tried everything I know how to do, but am to the point where I am forced to look at new hardware because my wife is pregnant and I really needs to be able to get a hold of me any time.

if you have CM recovery or TWRP you can go back, wipe everything even twice could help, then flash a stock rom reboot and see what happens
if that doesnt work go back to odin and install stock firmware 4.1.2 from Samsung but again you have to wipe data/factory reset
3rd if that doesnt work, try to restore your EFS folder/files using this link http://forum.xda-developers.com/showthread.php?t=1725839
that link has everything, how to fix it, anything you need to know
BUY a new phone or use a different phone if all the options above fail

The backup restore/fix imei and data restore tools link doesn't go anywhere, does anyone have a link to the restore tool? The only version I can find is for the non us version of the s3.
I did at least use the tool for the 9300 to find out that I have some 000 for s/n and other numbers (see attachment)
is there a patch out for us gs3's to fix this like there is for the i9300?

I think I can help, I just need to pull up some files and I might get you the software or program I used to back -up and restore my EFS folder/files
Even fix it, so plz hang in there........will report back later on
Thanks a bunch, I am still trying all kinds of stuff but I feel pretty certain that the problem lies with a messed up efs and I don't think I have a backup unless doing a nandroid covers that as well, which I am not seeing that it does. Any further help is appreciated, is this something that a local cell repair shop can typically fix or is this a possible new phone situation?

this is the software/programme i used to back-up, recover or even fix my EFS files (if they are corrupt and can be used) NV items reader writer
type it on google and pretty sure you will find something , try different links and again am sure you will find a download
have you tried flashing the new 4.3 stock firmware and modem follow this link for everything http://forum.xda-developers.com/showthread.php?t=2498233 or you can wait for AT&T to release the official 4.3 firmware and that will be 100% satified to be stable and will fix all your EFS/IMEI problems FOR GOOD :laugh:
i have the NV items reader writer software that can fix your problems but i dont know how i can share it with you without breaking any rules
ULTIMATE/final solution send it to MOBILETECHVIDEOS and will fix it like its nothing, take it to samsung and have to play some ball, or BUY A NEW PHONE
tried kernels (idont think it will make any difference) but its good to check
I have tried all the other versions but will try the 4.3 what's the name of that software so I can try and find it or of you have drop box you could pm me the info and get it to me that way . In the meantime I found an fusion 2 for 38 bucks from att so I can get calls for the time being.

[Q] Mobile data suddenly dropped

I'm running CM-10.1.3 (stable) on my phone (T999) with the UVMD5 modem and last night I lost all signal for about 30mins. I rebooted a few times and toggled air plane mode on and off without any success. Eventually, I got signal again but no data. I can send and receive calls and SMS but I have no data connection (can't browse, no email notifications, etc.). I have tried all the options under the Network Mode settings without any success. Occasionally, I'll see the "E" sign for Edge/2G but there is no data available even then. I also tried updating the modem to UEMJ4 and UEMJC but observed no changes. WiFi works just fine. Could this be a hardware issue? Is the antenna somehow damaged? Is there anything else I could try?
Try another Kernel. If that does not help, Odin flash to Stock. If that too doesn't work then suspect tower issue.
Hardware is a possibility. But lets not get ahead of ourselves
Thanks, I'll give that a shot and report what I find. I doubt that it's tower related since I'm having the same issue at home and at work and my roommate, who has an original Galaxy and is also on Tmobile, is not having any problems.
I flashed stock JB 4.1.2 (UVDMD5) using Odin since I had it laying around and I'm still seeing the same issue. What else can I try?

Check your APNs. Those are under Settings > Advanced > Network. Its called Access Point Names. It should be set to epc.t-mobile.com. See this thread for details.
Try UVDLJC or the prior version to MD5. If that too does not help then take to T-mo for antenna Repair.
Check your IMEI number. If it is zeroed out PM me. Otherwise just let us know here, (but don't actually post it).

The IMEI is 0. I never backed up the EFS folder but I was able to get the number from tmobile.
I have been having the same issue since June 2013 after doing to 4.1.2 OTA update from T-Mobile, at the time I didn't realize the IMEI was listed as unknown. So for months I have not gotten a cellular data connection better than Edge. Also after that update trying to check for a software update on the phone resulted in an error, and Kies told me my firmware was not supported for upgrade. Looking in some support forums and talking to T-Mobile got me nowhere, so I have just been dealing with it.
Wanting to upgrade I recently used Odin to load the official T-Mobile 4.3 ROM on the phone, actually hoping that would fix my issue (still in the dark about IMEI) which it did not.
I had never backed up the EFS folder, since as a standard user I had no idea what it was and while performing an update from my provider I didn't realize anything would need to be backed up outside of Kies. Now that my warranty is expired and having to take matters into my own hands I am on a quest to find a fix, however I don't want to "brick" my phone in the process, at this point I know enough to be dangerous.
Currently;
Android 4.3 Official T-Mobile ROM
BASEBAND is good T999UVUEMJC
Kernel 3.0.31-1962493
IMEI is Unknown
Looking at some other posts here at xda-developers I tried to follow some instructions on repairing or restoring IMEI using NV reader/writer, however I cannot get NV reader/writer to connect to my phone.
I have noticed in 4.3 when using *#7284# in the dialer the QualComm settings are no longer present, only MODEM and PDA are available.
I have poked around in Service Mode *#197328640# and found a setting that I thought might help, but I have a feeling it is the same thing as 8#7284#
[1] UTMS > [6] COMMON > [4] DIAG CONFIG > [1] USB or [2] UART
So at this point I don't know how to proceed, again I am not thrilled about loading a custom ROM, or really any ROM for fear of making the issue worse or bricking the phone. I have read a lot of posts about no longer being able to make calls due to IMEI issues. Everything works right now except cellular Data.

[Q] Cannot call or receive calls, but can text and use 4G

Ok so I did a ton of stuff to my phone like rooting, flashing different ROMS, but in the end I want to get my phone back to stock, so I flashed the stock firmware with LG Flash Tool but now I can't call anyone and incoming comes don't come through. I just get a "out of service area" after a while whenever I try calling someone. Texting works and internet works, and so does Wifi. Also, my time is 3 hours fast when it's set to automatic in the settings. I don't know why it's doing this. And my IMEI is 0. Here are some pictures of my settings. One more thing. Since I flashed the stock, in my android devices, Google doesn't recognize my old device anymore. It treats this phone like a new device now. Weird... Anyone know how I can fix this problem?
Oh and when I try to update my phone it gives me this: "Your phone is not registered yet"
So many problems, I'm so sad
(these are the images uploaded online if the attachments don't work)

Do you have a EFS backup? Your IMEI is 00000000000000.... That's NOT the way it should be. Maybe the network provider blocks you from using the network because of an invalid IMEI (don't know for sure) but since you reflashed Stock ROM i don't think it's modem related...
I think I fixed it! I just used the kdz method of going back to stock instead of the tot/dll method and it fixed my problems! I got it from this thread if anyone else has the same problem:

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.

I did try factory resetting and I am on stock after flashing the RUU. It makes no sense as the RUU should have reset everything. That perplexes me the most

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. You also removed and reinserted your sim card as I believe, correct?
EDIT: that perplexes me as well my friend!

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.

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.

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.

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. You also removed and reinserted your sim card as I believe, correct?
EDIT: that perplexes me as well my friend!

The first time it happened, I flashed back to stock using the RUU.exe. I tried again but the second time I took out the SIM card before running the program, I still can't get LTE.

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.

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.

Network configuration corrupt with Cyanogenmod backup.

Hello, so here is my problem. I have been using Cyanogenmod 13 on my LG G3/ls990 for months now. Recently I needed a static IP address through Sprint. When they applied the static IP to my account, I was stuck on 3G, even though I mostly have LTE. Basically what I did was use an old stock rom backup to update my PRL/Profile. This brought back my LTE service. Then I reloaded my CM13 backup. Unfortunately, at first it didn't recognize my sim card, and then it only recognized 3G. Okay, so no problem, I decided I would just go back to the stock rom and clean install a new custom rom. Unfortunately, when I went back to the stock rom, it was also stuck on 3G and this time when I tried to update the PRL/Profile it didn't work, I am guessing because it already saw these as updated. So after a few chats with Sprint's tech support, I was able to get LTE to work again. She said a particular network configuration file wasn't working right, and she did something which was suppose to fix it. As instructed, I typed in code ##72786# after she did it, and LTE worked perfectly. Stupidly, I thought it would be as simple as reloading my CM13 backup. Yet it did it again when I loaded the backup, and now I am stuck on 3G again. Before this I didn't really connect the two together. Does anyone know what exactly is happening here? Tomorrow I plan to call Sprint again, to get them to fix the file, but is there a way I can do it myself, in case I have this problem again when I install a new custom rom? For example, if I go into ##Data# will I fix things by changing a setting in there or something? I hate having to talk to Sprint every time this messes up, and yeah, I know it was stupid of me to do the same thing twice, but it was a day apart and I forgot what I had done the first time. Hopefully whomever I talk to tomorrow can figure out what the woman I spoke with did, because she definitely knew what she was doing. Thank you for all of your help!
Update: Called Sprint they reset my network and I have LTE again. I am somewhat wary of installing a new rom but would like one for resolving performance issues and wifi tether. I downloaded an unofficial Lineage 15 Rom yesterday while I was on 3g only, but it couldn't find my sim. Is there a way to backup my current network settings?
Update 2: So I just tried a fresh install of Lineage 15 and it didn't work. First it recognized cell but no data. Then I went into data settings chose carrier settings that crashed, "android.com. [something]has stopped working" , the sim was unrecognizable after that and the carrier settings weren't there any longer. I backed up my EFS partition in the stock rom before installing, but then I was stuck on 3g even despite that. I called Sprint again, and got them to reset my network settings. Don't want to keep calling them though.
Anybody here with Sprint and a static IP that can recommend a ROM that will work and not mess up my network settings? I don't care if it is Marshmallow or Nougant, I just want something that doesn't overheat my phone and which I can have native tethering.
EDIT: I was able to install Fullmics and retain my LTE.
