Develop Bugs

[Q] stuck on edge still

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

Worked for me too!!! Used nv backup from wife's phone.....I had tried everything and was about to give up....Thanks for the info :victory:

So I can just get ahold of a friends galaxy 3 and copy his efc folder onto my phone.

A true fix

3G download problem. HELP!!!!!

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.

Sent from my SPH-L710 using xda app-developers app

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.

I've tried this with the exception of rebooting my phone right afterwards. I just updated my PRL but I could not update my profile. I got an error. I'm running out of options
I appreciate everybody's help though.

This happens to my wife all the time on her evo lte, trying again 15 to 20 minutes later usually fixes it so she can update profile and prl
Sprint GS3 FAQ THREAD

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)

Same thing started happening to me a couple weeks ago. Tried everything. Only "fix" was setting network to CDMA only. Frustrating.

[Q] Is this blocked IMEI on my Note 2? im confused :(

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)

Try switching the phone to 2g only ! *#*#4636#*#*.

Try calling tmobile with a differnt phone.

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.
Thanks for all your help :thumbup:

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

im having same issue but i can actually make calls and get text, the data side isnt working , sometimes it kicks in but its more on no data than on
im calling for a replacement tomorrow this was a replacement from a bad usb port phone i sent 2 days ago , tried everything and i know its not network cuz everyone in my house has t mobile . hope you figure it out as i gave up

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?

I actually just updated to the OTA MD1 update and still the same and my wife has T-Mobile aswell she has an iphone 5 and she never looses service here, not too mention we get LTE already in our area but she always has full or almost full bars, as for me as im typing this now this is what mines looks like but yet yesterday in the night I was getting service and 4g LTE
Im starting to think maybe its a hardware problem with my cellular antenna cause my wi-fi antenna works just perfect or what else might it be?

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.

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 antena problem. Had that happen to me with my skyrocket. The one end was not connecting to the right place. Somebody accidentally cut it off when I had the speaker fixed.

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.

HELP, no connection after flight from NC to TX

Hey all,
I could really use some advice. I live in North Carolina, my phone has worked just fine for over a year. Monday I went on a business trip to Dallas Texas and my phone won't connect to Voice or Data services at all. What can I do?
I tried turning airplane mode on and off, removing the battery, chatted with Sprint online, called the Support number. Sprint is NO help at all. They didn't outright tell me that my phone was broken, but practically did. I guess it just magically broke on the plane to Dallas??
Even in areas with good coverage, like my bars show good connection, I can't connect. I can hook to wifi just fine, but that is it. Sprint support told me that they can't even see where my phone has connected at all since I arrived in Texas.
Should I try flashing one of those PRLs from another thread? I'm not sure what to do. I assume that as is my phone will start working again when I get back to North Carolina though. I tried reflashing a "stock" rom and some of those "#" number calls, but none of them work since my phone isn't connected to any towers. Help!

That is what is so strange, I can dial that number, even from a stock rom, and my phone doesn't do anything, it just sits on "dialing" then makes the hang up noise after 15 or so seconds.

That's definitely weird! I'm from this area so I know it's not the water...lol. Have u taken to an actual sprint store?

Not yet, since I'm here on business I don't have much time to do that, but honestly I don't think they would be able to do much more than the support person over the phone did. I'd have to unroot it and all of that before bringing it in, the folks in the store would try those ## type calls, wipe my phone and reset it, then probably tell me my phone is broken and try to sell me another phone, especially since I am eligible for an upgrade.
I don't want to actually buy a new phone until I get back to NC since I still think my phone will start working once I am back there, which would be just as confusing.
This is the same phone I brought here to Texas last October and it worked fine, so I don't know what exactly the issue could be.

If you are still having this issue I would suggest you try an app called Network Signal Refresher. It basicly updates your prl and profile by connecting you to the nearest tower

Thanks, I gave this a try, but it doesn't look like it worked. Part of the issueI think even for PRL updates is that my phone won't connect to the towers. Like with a Stock Rom in the Sprint Zone you can get to that section where you can do a Profile update and all of that, it always fails with a connection error. I gave that error message to Sprint support but they couldn't do anything with it. I will keep trying it though now and then.

Is there a good updated guide for doing that? I did that on my EVO 4G, but never on the S3. I haven't looked yet but I will check into it this evening for sure.

They could be working on the towers in the area. When they did in my area, it showed I had bars but could not text or call. I would try flashing the 2 PRL, as it helped me get my phone working until they fixed it or in your case until you get Home. I can upload it if you need it.
