I'm another victim of the dreaded imei =0 bug. I injected my imei back and also used the danx tool to get me back on 4g by following these directions but no dice.
If i force wcdma i can get 4g for a minute before the signal bar drops to nothing and eventual the connection dies and my carrier text than says "Unknown".
I called tmobile and they tried to reprov my line but still only 2g.
Anybody have any similar experiences? Any suggestions to get 4g back?
Yes unfortunately I sent mines in for warranty exchange, waiting for the replacement device.

If you backed up your IMEI then Inject the imei and then flash a different radio.... Don't quote me on this but I believe a member or two did that and got 4g back... Like I said in going by memory so I'm not sure if that is what they did

I have suddenly been having problems with my 3g. I look at the symbol in the status bar and it will upload but it will not download. It's almost like the code is stuck in a loop. It will randomly start to work again for awhile and then act up later. I have wiped dalvik, cache, and I even reflashed my ROM (FREE GS3). I updated profile and PRL. That was even a problem because I would get an error since it wouldn't download. Before I flash back to stock and call sprint, does anybody have any ideas? One other note. I have driven through LTE areas and both downloads and uploads work with no problem.

Before reflashing call Sprint and see if they are doing tower improvements, this can cause that when they are working in things
I'm going to flash stock and unroot to see if that helps. I work 75 miles from my house and have experienced the problem at homd and at work so I'm pretty sure it's not a tower issue.

Try updating PRL and Profile then restart the phone? That may help, I mean if it does then you just saved like an hour of resetting and restoring. If it doesn't then you just wasted maybe 2 minutes.

Happens to me when I shut off data for any length of time....I just reboot...and it works fine
I called Sprint and they couldn't fix it. I switched the network mode to CDMA from CDMA/LTE and it worked flawlessly. I don't know what that means but something told me my LTE and 3G weren't playing nicely. Whenever I go through a 4G area, it works to perfection. Then I get back in a 3G area and back to the same old thing.
I forgot to mention I flashed to stock unrooted and it seemed to function better but the problem still existed.

I have the same problem I have no idea what to do. I have a custom ROM the only way I get it to work is when I toggle Data on and off really fast. I didn't try the CDMA only though. Either way it's no excuse why our phone's are acting like this.
There was a DATA_HANDOFF.ZIP floating around somewhere....it was made for AOSP but if you make a backup and flash it, it might do some good
I had the same problem. In your phone key pad enter ##72786#. Its going to do hands free activation, prl update, profile update, firmware update (at that point you can cancel)

Hoping you guys can give me a hand. I'm fairly new to the GSM side of things. Too many years wasted on Sprint. hehe
So I picked up a used 32GB Galaxy S3 from some guy on craigslist ($340). it was in great cosmetic shape and i tested it before making the deal by making a phone call (with my SIM). it worked, deal made. we picked up a new SIM, i unrooted (it was kind of a mess), did a full factory wipe/reset and performed all the official t-mobile updates.
the device works fine and can make calls without issue but will not switch to HSPA even when my Nexus 4 and daughter's GNex are on HSPA+. It remains stuck on edge.
Galaxy S3 T999
IMEI matches with the IMEI on the back of the phone
Most recent baseband version (T999UVDLJC)
Flash counter showed 15 but status is normal and allowed me to run t-mo updates. i didn't bother with the triangle away app when unrooting since i did not intend to take it in to be serviced. i just wanted it back to stock for the wife.
I ran through all the troubleshooting with the t-mo tech support and nuthin'. Any ideas/suggestions?
thanks fellas. and yes, i did try searching for this problem. the closest thing i found was people talking about a corrupt IMEI number but the IMEI seems to be fine.

What happened is the phone lost its IMEI and the previous owner did not have a backup of it to restore properly. This means he had to inject the IMEI, which has caused people to lose 3G/4G connectivity. This thread should help you out.

Im a little confused and im wondering if someone can help me out or if someone is going through the same thing i am.... :crying::crying::crying:
So i just got a Galaxy Note 2 from my fathers friend at work and i am wondering is this considered when they say being a blocked IMEI cause its a little confusing...
So I have T-Mobile and i received the Note 2 it is not rooted or anything and the IMEI matches the same in the "About Device" and in the back behind the battery so anyways i go and pop my micro sim card in and notice right away it gets no service it just has a circle with a horizontal line accross like seen on the pics and the lock screen just says "Searching".. i go into mobile networks and try to manually select the T-mobile network and it just gets stuck on "Registering to T-Mobile" then i get an error in my notifications that says "No Service Selected Network (T-Mobile) not available" so right away im assuming that the IMEI must be bad so i call T-Mobile give them the IMEI and they tell me its NOT blocked so now it gets confusing.
while i was still messing with it i decided to turn ON wi-fi and all of a sudden the wi-fi calling feature turns on and viola! the circle with the horizontal line changes to empty service bars and in the notifications dropdown it now says T-Mobile so i go on and make a call IT WORKS! send a text IT WORKS receive calls and texts ALSO WORK! now isnt that wierd?
what do you guys think might be wrong with the phone is the IMEI really blocked but if it is will i be able to make calls and send and receive texts i dont understand please some one help me any advice will be appreciated.. :fingers-crossed:
Thanks (here are pics of screen shots)

Generally, when your IMEI is blocked, you'll have bars and even data. Your phone just won't work. So I doubt it's that. The fact that WiFi calling works tells me that the SIM reader works. Do you know if the phone was taken apart? Maybe the antenna is messed up. Id just try going somewhere else to use your phone and try.
Possibly root and flash different modem?

The sim card reader does work cause sometimes out of the blues the phone will register on the network and im able to use it fully as it should and then it goes back to having the little circle with a line accross it.... today it behaved preety good it gave me a good amount of time of usage but it would still randomly cut off and come back on..... as far as being opened im starting to think it maybe was opened or something cause it doesnt have the "VOID" sticker on the screw in the back like it should..... and maybe what u said about flashing a different modem how can I check what modem I have now?? Cause the phone was rooted and had a custom rom but I restored it back to stock with Odin not sure if doing that will restore the stock modem or not.

I don't think there actually is a void sticker.. When I opened mine up, I didn't find one . I could have just over looked it possibly. Just try flashing JediM14. Comes with everything you need much better than stock. I'm thinking maybe tmobile is working on your area so you have intermittent service. Could be anything. I'll try to help you look into it. The sticky for the modem, ,facotry img and such is in android development. I think the sticky thread is in top three. It's obvious

JediM14 comes with the new MD1 firmware. Everything is for Tmobile. During installation, I think aroma gives you options for modem..not completely sure . but if you have tmobile, I'd stick with tmobile modem. Does anyone else have tmobile at your house you can compare signal to?

As long as you're stock and unrooted, you might be able to get a warranty replacement. I know you're not the original owner but it really depends on the rep that you get on the phone. If you get the right rep they'll warranty it based on the fact that no matter who originally purchased the phone, there's no way it could be more than a year old. Or, if you have the premium handset protection, you should be able to get it covered under the extended warranty that it offers.
Sent from my SGH-T889 using xda premium
Call Tmobile and tell them your situation. They'll reset your connection to the towers and it might help. They've done that for me. Just ask for like a connection reset. Even better if you just told them what's happening.

Could be this. I bought a replacement loudspeaker that was apparently for the T889 (which it wasn't)..[Most loudspeaker modules that say they are for the T889 are missing the third contact.] It was a missing a antenna contact which totally killed my reception. Try to take it apart and look at the loudspeaker. There should be three white tab looking things on the module itself. If there's only two, then that's most likely the problem.
Ok so I had an LGOG that functioned 100% that i sold on Swappa. It had a few small cosmetic imperfections but that was it. Now here is the problem, the guy that bought it is saying that the 3G chip (his words) isnt functioning. That 4G works no problem but his area doesnt have 4G. He said that Sprint told him that the phones profile wont update and that the phone has a hardware issue that they cant fix. He received the phone on August 19th and just notified me of this today, 4 days later. My question is this, if he tried to unlock it and root it and all of that without backing up the EFS and stuff through FreeGee or TWRP would it cause the problems that he is claiming? Really could use some advice from a Dev or anyone that can help. Thanks!
is it on a stock rom?
Yeah as far as I know. Claims he took it to sprint so I'm guessing it's stock. It was when I sent it.

How would he know 4g works if he isn't in an area that doesn't have it.. Can u do a three way with him and sprint and yourself ?
To me it sounds like he did a bad ROM flash .... I know if u flash a gsm ROM it messes up ya 3g even after lgnpst back to stock...
If he did try and flash or fregee it ... He may could of corrupted his efs and at that point he is Sol and can't hold u responsible ...
Could of flashed that zero efs file and doesn't know how to reprogram the settings for 3g to work ... If u do that 4g will still work no matter what ....but no 3g until manually programmed ....

I went to a metropcs store and had the phone activated and sim card inserted, my imei was connected fine and everything went great.
I instantly had EDGE(1x or 2g) and even after hours of searching and phone calls to metropcs all i can find is APN solutions that dont work.
I currently live in Dallas/Ft Worth so i know the LTE coverage for Metropcs/Tmo is amazing it just ill not connect to LTE.
How do i get LTE to work on this device ??

Worked fine on At&T for LTE
Su keeps for closing at start because it says security issues
Stock rom on 4.3 but it says custom build under about settings for some reason.

This issue seems popular this week.
If it's like the others, it's an issue from unlocking. the nv file gets damaged. The solution so far is to use nv-reader-writer to copy another phone's nv file and replace yours with it.
have you tested *#*#4636#*#* method? just mess around with the preferred network and see
I'm on Tmobile and worked fine with LTE
Where could i find a nv file for the s3 i747?

Sir, i tried to use the nv tool but it keeps saying phone wont connect.
i have the drivers installed, it sees my ports for the phone, i go to connect and it does, but when i click read device it fails. Ive had no boxes checked, one box checked and both boxes for spc and fast read(i think it is) checked. No Go either way. Any suggestions for this? Then i can see if the NV Writer is a solution. Also i can use my own NV file right??? Or would that just be a corrupted file being reloaded ?? If thats the case how do i find a clean NV file for a Samsung Galaxy S3 i747 for AT&T??? Thanks again for the help brother
I would think you would need to load an NV of a different s3. I will try to load my NV here in a few and see what happens. PM me also

Ok guys i tried some settings. a guy i know tried to inject the AWS for Tmobiles band freq. and it didnt work.
SOooooooooo im thinking we might have to skip AT&T phones on metro/tmo and get a tmo phone or a AT&T phone that supports AWS band freq.

Will this give me LTE? I am able to get h+ but my phone does love to set on edge.

Wait....How are you getting 4g ?? it might not be LTE but da*m its faster than Edge. Could you tell me your apn, and your settings if you changed anything since you first switched to metropcs.
Like dial star, hash(number sign)twice, the 4636 and star,hash star, hash and go to device info, then screen shot, then scroll down and screen shot again where i can see "set preferred network"
also man are you sure you have the S3 I747 from AT&T??
Make sure you are checking your connection in Settings > About Device > Status > Network Type
You cant always trust what's displayed in the status bar. Especially when using a custom rom or using a device on a different network than it was intended for.
Yea man I know. I've checked everything and says edge still.
I think it's based on your radio and kernel. Brad what kernel and radio you using.?
I'm on 4.3 Rooted and stock.
