Injected IMEI SGH-T999V stuck on Edge network Please help get 4G back - T-Mobile, Samsung Galaxy SIII

Hey everyone I've been searching the whole entire internet and xda to
find out what I need to do exactly to get back LTE. I lost my IMEI after
upgrading rom without backup of efs folder. I was
able to get the IMEI injected manually with NV writer/reader so I can
connect to edge but only edge network 2g mode. What do I need or
install or do to get back 4g. The thread that people point to others that
ive searched is deleted thanks

Any ideas? I even tried different modems etc but still same problem... I'm now also on slim bean rom 4. 3

Any help

[Q] Made a bad flash worse...

I have a Samsung Galaxy S II E4GT that i had someone "professionally" flash to MetroPCS . He cloned a donor phone but I had difficulty activating the phone with Metro on site . I returned to him after the account was activated but he never completed the flash. I set out to finish it myself... had phone (1x), sms & gps all functioning on FI27 ROOTED NoData rom and then went for 3G... I now have nothing functioning but wifi after following a procedure on another site to change APN's... I do have a backup .qcn and of my efs folder along with anEFSProBackup file but no diagnostic modem or access to DATA settings. No MEID, etc...
Any help would be gratefully appreciated.

Look up Chris41g's steps to flash over to Boost. This will give you the steps to get you in the right direction. (Sorry but XDA doesn't allow much more to be discussed on the threads about this.)

Impossible to get network operator

I flashed CM10.1 on my S3 and had the same problem as others where data was intermittent. It worked for some time and after one nightly, I lost my IMEI. So I got back to stock, used the procedure with QPST and got back my IMEI. I got back to cm10.1 and unsurprisingly, I had a hard time having data. But worst off, I had a hard time having cell connection anymore, not even voice or sms. Tried AOKP without any luck. Tried different modems, not luck either. Now I went back to stock and still doesn't work. There's something that is not resetted between flash of ROM that keeps messing up my connection. I also found out that only one network provider is ever found, one is Rogers Wireless (I'm with Bell), or one is EXT. But never any other provider is ever found. And also in *#*#4636#*#* under phone info I can'T change the radio band like I can on the phone of my girlfriend.
So there it is. I'm stuck. I don't really want to buy another phone. It is a software issue for sure. But how can we solve that? Is there any way to restore the EFS to factory default? Could it be buried there? What is the ERI? Could it be that? My stock ROm says that it can't get the ERI version.
Any help is welcome.
my stock telus ERI is unavailable but i think thats normal... i have no problems
from what i understand imei and apn settings are the things to check into

IMEI and APN are good. IMEI will get me data, but I can't even get a cell connection now. No radio at all.
whats your radio band set to?
if i set mine to anything but automatic it wont find networks like yours..
*#*#4636#*#* dont work on my telus s3.
i use a different method
*#197328460# then
UMTS > Debug Screen > Phone control > Network Control > Band selection >
Automatic...
beware what you change in here as there is no return to default

Neither of the two works. *#*#4636#*#* was working with CM10/10.1 and AOKP. But not with stock. And the one you suggest after is not working either.
But I remember going ot *#*#4636#*#* before flashing stock rom and I wasn't able to selet any band. On my girlfriend's android phone (HTC) I can.
if it were me.. i would try reflashing stock again... after flashing stock do a factory reset thru recovery... seems to help for clean stock setup.
if still no network i would check that band selection is set to automatic.
maybe someone else with more experience would have a better idea.
you mentioned you changed your band selection and now cant change it back.
i dont think flashing stock changes this.
i think that might be your problem.
ifso you first need to fix phone to use *# code... i have no idea why its not working
it works on my stock telus 4.0.4 and 4.1.1
maybe bell blocks from using *#code?

if i were u i would first try your girls sim in your phone and vise versa and if no luck do the qpst instructions to regain LTE not imei .and if u still cant manually find network operator after that i would format both sd cards and odin back to stock rooted and do the imei injection again for the hell of it and the LTE fix ..and stay on stock rooted or 4.1.2 until u get this figured out cause 4.2 builds are gonna have more probs then 4.1...I know u are having cell connect probs and these instructions are for imei and data but it sounds like your out of options....i lost imei once and had to manually inject with qpst and my reception was one bar til i did the LTE fix and it worked awesome..one more thing is my phone will not select a radio band ever unless i manually select my network operator first or i have no sim card in phone..i have also had sim cards crap out for no apparent reason..good luck
edit. my bad i thought your girl also had gs3..maybe the sims are still the same

Thanks for your answer. Really appreciated. I've flashed so much time that I don't see the point of doing it again. I also had, at some point, to inject my IMEI and it worked with QPST.
What I find really strange is that a stock reflash doesn't put everything back to when I bought the phone. Funny thing, after the flash, it knew what my Wi-Fi router password was! So obviously there are some part of the config that is not overwritten. Which I find odd.
I also started playing with the service menu and found a lot of settings for the radio band. No luck yet.

Your WiFi password could have been restored by google just like it puts your contact info back.
If you are doing a Odin to stock that should wipe it clean.

This thing is so strange. There's only one network that my phone can see now, and it is 302720. Bell is 302610. No other network is visible. And since I'm with Bell, then I can't connect to 302720. I'm in for emergency calls only. That's why I thought it may have to do with radio. But it seems Rogers (302720) and Bell use the same bands. A channel maybe? But this should be all automatic! It's a pretty stupid bug let me tell you!
Maybe a SIM card issue? That would be quite a coincidence that it happen exactly when I'm playing with ROMs...

Ah that's a good possibility. I didn't know it was saving passwords as well.
So if it wipes clean, how come this bug stays? There is obviously something that is not wiped and overwritten or else it would work.
How can one tell if someone losses their IMEI number? Unable to make phone calls? No 4g/ lte?

When you go to info about your phone, in status you usually have your IMEI number. It'll show 0 if it's corrupted. Or sometimes it's a generic IMEI dans is used when the real one is unknown. It's 049 something I think.
Without an IMEI number you can do phone call. But you'll never have a data connection.

[Q] Data problems... posted solutions aren't working.

Almost a week ago now, i decided to flash a 4.2 aosp rom on my s3. After the flash i couldnt get any data over cellular network. I noticed my IMEI was 00, so i followed the steps on http://forum.xda-developers.com/showthread.php?t=1804123 to restore my IMEI. After my IMEI was restored i was able to get data that immediately dropped down to edge netowork. In my area we have no LTE with at&t but we do have hspda+ with strong signal everywhere. I eventually found http://forum.xda-developers.com/showthread.php?p=29461950#post29461950 and i have taken every step on this post, now multiple times, with no change. I have flashed back to stock with odin and tried it all again. I still have edge network only. At this point I will see 4g for at most 30 seconds after every reboot and then immediately lock into edge network. I feel defeated. I can get my phone replaced under warranty, but at that point i will be afraid to modify it anymore. If i find a fix i can feel safe using my phone unlocked/rooted because i will know how to fix it.
Please if anyone has any tips or help that i can try, let me know. Im desperate at this point.

Your solution fixed the problem. Thanks!
I also had the same identical problem,, I followed the steps by selecting "all" on all 3 , and then selecting "automatic", but it loses 4g after just a few mins.. I restored the IMEI, replaced the sim card, and everything.. We don't get LTE here but I still selected "all"...

[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

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] LTE issues after cm12 (virgin mobile a5_chl)

So as the title states I have the virgin mobile a5_chl variant and after flashing cm12 (build 05052015) I can no longer (or at least hardly ever) gain LTE signal back, no matter what ROM im on. It comes across saying I have no service and no signal and I can't text or call when trying to use LTE.
I have done the following to try and fix:
1. flash apn fix (obviously)
2. restore stock backup
3. try a different rom
4. completely RUU back to stock.
I believe the issue lies somewhere within the HtcOMADM_SPCS.apk but I'm not 100% sure about that. According to any thing i've found the HtcOMADM_SPCS.apk is the "vDM client" that allows for profile updates (when i try to do a profile update it either says vDM client has stopped responding or the the profile update could not be completed). I've tried uninstalling and reinstalling the HtcOMADM_SPCS.apk but that only provided a fix once and when i rebooted my phone I lost signal again.
I'm pretty much at a loss as to what to do as virgin mobile gives me the usual run around that they are "having tower issues" so I'm hoping maybe someone on here can help out. If you need any further information please ask and I'll provide, I tried to be thorough when creating this thread. Thanks for any help.
BUMP / Can someone from VM USA upload a copy of the HtcOMAD_SPCS.apk it can be found in system/app/HtcOMAD_SPCS. It would be very much appreciated if you could
