Okay, I have a PLAY 4G that I got from AT&T so it's an 800at. Used it with AT&T for about a month, canceled, got the unlock code form them. Switched to T-Mobile prepaid $50 plan, used it for around 5 months. A few months into T-mobile I rooted it with Super One Click, everything was fine. Now a few months later my signal to T-mobile started cutting in and out 2 days ago. After about an hour or two of losing the network it finally never came back. I did all the standards, resetting, popping battery in and out, etc. Still didn't work with T-mobile, tried SIM in another phone, it works fine. Also got a new SIM from T-Mobile, no difference. Unrooted phone with Super One Click and no difference, did all the resets and battery in and out. Still won't work with or even see T-Mobile. Put an active AT&T SIM in and it works fine! So it seems the phones hardware is fine and the SIM is fine. My last hope is I have a software/firmware problem. One thing that's weird is after the master reset the Home button stopped working and when the joypad is slid out it doesn't switch automatically to games. Phone always says "Emergency Calls Only". Please help, I'm running out of idea's.
I do believe APN's are the problem.
Had to deal with the same thing when I switched to straight talk.
Game stuff and the home button seems like a software issue.
Reflash 2.3.3 stock for AT&T phones. Should be fine after you reset the APNs
Still Stumped
Thank you for your input, I deleted my T-Mobile APN and re-entered it, and it's still not finding the network. I've been wanting to reflash the original firmware back on. Do you know if I have to unlock the bootloader to do that? I was going to try a different ROM but my warranty is still in effect for 6 more months. I'm thinking reflashing the original ROM shouldn't need the bootloader unlocked. I also need to find the original ROM to reflash it with. Is it safe to reflash a generic Xperia PLAY ROM instead of AT&T bloatwares ROM?
I would use flashtool to reflash the AT&T ftf, then just manually input the APN settings for T-Mobile. That should do the trick. IF you try and still a no go I would unroot and soo about a warranty replacement.
You already voided your warranty when you rooted..
Can they know that you had rooted it if you unroot it?

I may be wrong but I thought that if you ftf back to stock they will not necessarily be able to se you have rooted your phone? As its fresh out of the box firmware....

Yes, but only if you bring it in to them or send it away to get fixed

No, flashing an ftf file still holds root and it evident.You can unroot, then reroot if need be,but personally I've never unrooted
Thanks for all the input everyone!
Thank you for all the responses, I will try flashtool this evening and report back what I get. In terms of root, my research has led me to believe that rooting/unrooting is undetectable. But unlocking the bootloader cannot be covered up, Sony has records of all bootloader activity. But I could be wrong, just tossing in my two pennies.
It's fixed!
I used flashtool and reflashed the original software back to the phone and it's good as new again. Thank you everyone for your input! I wish I could tell you what caused the problem, but I'm happy I could at least relay what the fix was.
I have a t889 and a original sim card which was cut to microsim form. I had no trouble getting service. I rooted successfully and still had service. At this point I performed nandroid backup and efs backup and attempted to flash jedi x following all steps provided in the thread (wipe data, cache, format system, wipe dalvik, fix permissions). As soon as I did this I lost service...it has bars but no voice calls and no 4g. My IMEI still shows however. I ve tried everything from stock factory restore through ODIN to restoring efs, flashing stock radios/kernels restoring nandroid still cant get service, defintely need some step by step advice on how to get back my service. I feel like I followed all the appropriate steps to flash the room.

How does the imei dissappear and how the heck do we avoid that?! Thanks so much.
I was in same bout as you. I used my insurances claim and got a new note 2.
Sent from my SGH-T889 using xda app-developers app
So did all of you flashed this rom and this happened to you?? Im confused.
I've been flashing phones since
<------
2007 and this note 2 I am terrified of flashing. every other day is a new thread just like this. Nobody knows why, nobody has a defacto solution. The only remotely close info I've read that works is to unroot and flash to stock. Even that is a gamble. If that does not work, consider it a loss. Sell it on eBay as a bad IMEI phone
Hey guys just fyi to let you know what I found with this issue. Just giving my input.
Well it looks like my imei is populating but my note 2 no longer gets service. Im probably going to warranty it so I can get service again I spent all of my weekend trying to fix. I think this issue may be related to something within the modem or radio being flash incorrectly and somehow corrupting the efs files. I searched forums about efs corruption and I think maybe it has something to do with a nv_data file missing? Not sure if that applies for sgn2 but I couldnt find or maybe I dont know WHERE to find it in root explorer. Maybe if we compare a working sgn2's efs file with a NON WORKING sgn2's efs file maybe that would help? I followed the steps in the t889 root guide step by step... and then as soon as I flashed Jedi 9 through cwm recovery BAAM...service was gone.
I tried reflashing, I tried reflashing stock modem\kernel and reverting back to stock via odin but no go.I did notice it was able to connect to tmobile for one to two sec because it would actually sync the time and date after turning on for the first time. But never again after that. My Imei and bars are showing ..but when I make a call it says "not registered on network" and no 4g either. I think this may be because the rom had included a different radio not sure which one defintely wasnt the canada ver. Flashing this rom somehow made my phone stop receiving service...Does restoring efs backup a guaranteed fix the lost imei/ service issues? Can flashing using earlier version of odin cause an issue? I used 1.84. Everything passed successfully however. Just throwing ideas to help. I definitely want to try to avoid the issue when get my note 2 back from repair.
I know that efs and modems are fixable but I believe there is additional steps needed to fix the imei... not sure if there has been a solution on that but im looking everywhere... found that you can pull your batter, write down your imei, us nv tool to create a nv file and flash it to the phone but not sure how it works with GNII... I personally havent had any issues so am not going to test with my device but for those with no service you could atleast try and report back for others... go to galaxynote2root website and find the videos on flashing tmo to att and vice versa, youll find the programs needed, drivers, etc and basic instructions to what im suggesting

Does the phone even register to the network? Have you perhaps tried a different sim? I know you will be limited as to the carrier but try a friends sim just to be sure. I'm sure you could even take the phone to the dealer and they will test a different sim in the phone.
Has your IMEI possibly changed somehow, maybe it is acting like conflicting IP addresses on a network.
In Kies there is an emergency firmware recovery, perhaps that could help. I know I am probably not much help but 1 cent worth of help is better then no cents.

+1. As a newbie I was able to flash anything on my moto defy / ME525 without worrying a bit of bricking it, but I could only eagerly wait OTA update on my T889V.
I've actually been experience serverely degraded service since I flashed MyRom Revolution v2 last month, and not matter what I flash since service is questionable. I'm on the latest Jedi -XX from the 6th, and my 4g/3g service is 90% not there anymore, and i will flip to edge sometime for roaming on AT&T even or jsut be without service altogether... I've flashed the lastest modem from the Jan 26th, no help. New rom, ... no help. I'm ready to have my phone exchanged as well. Any ideas ?
Some people were having issues with the January 26th update flash back to ll4 and see if that doesnt improce things... also seen a thread refering to band 2 issues with one response refering to ATT towers... did you by chance ever download a ported ATT rom with a modem part of the install by chance?

can AT&T deactivate my SIM or block my IMEI if they detect a custom ROM?....my SIM is not working anymore I Rooted . FreeGee'd and Restored to this ROM
http://forum.xda-developers.com/showthread.php?t=2419802
I got 4G LTE fine (after changing to a different "pta" APN) but couldn't call. Found out I flashed the baseband for the E988 instead of the E980. I went to CWM and flashed the proper AT&T E980 baseband after a CWM wipe and restore again....my Sim still wasn't working
I saw some things that AT&T can deactivate a SIM if they detect a break in...can i just buy a new SIM?
I used the LGFlashTool. flashed back to stock completely. (relocked and unrooted) and it still gives me the red "X" near the signal strength and it won't save APN's
contacted online tech support said that "AT&T deactivated my SIM card as they thought my phone was being broken into and they thought it was stolen" is this something new? can I just get a new SIM at the AT&T store?
i've rooted and flashed an (including my significant other, co-workers at various places of work and my own handsets) HTC thunderbolt, HTC rezound, 2 Galaxy SIII's, a LG Optimus S, LG Optimus V, ZTE Warp,Galaxy SII, and even a Droid Razr and I have NEVER had the provider deactivate the Sim card because of hacking.
was the tech support person "Andy" trying to scare me?..is it true?..or did I bork the SIM by flashing the wrong baseband the first time?...because my SIM still isn't working
any advice would be greatly appreciated!

No just go in tell them your SIM card isn't working and you need another.. those people working at the att store don't care if your rooted or running custom roms.. unless your trying to do a warranty return...
sim card replacement should be free also
turns out....it wasn't the SIM card....new one was put in and it still didn't work..the guy looked at the IMEI and it said unknown....had no idea how it got there...but made a jab at LG for making cheap phones and said "theres a reason why we dont carry LG" .fortunately I was still in the return window process and got an exchange same day at a nearby corporate store...do you think it was something I did?
either way..not rooting or flashing until a year has passed

Thought I had read on some of the ROM threads that flashing an incorrect baseband can cause some major issues, such as wiping out your IMEI...
You simply needed to use LGFlashtools to return to stock and your phone would have been fixed. Always make a backup of your currently 'FULLY' working Rom that way if something goes wrong, you can return to stock and be up and running. What happened was that your baseband was incorrect after flashing the wrong modem. Flashing the correct modem didn't fix it fully because that partition became corrupt. Restoring a fully functional backup would have fixed that issue.
Glad you got your phone returned though. Hopefully they don't bill you when they see that your phone is rooted and hacked. They might.

oh no problem..they gave me a new phone because i returned it back to stock using the LG FlashTool
It was your own fault not the phones. Flashing an baseband not meant for your phone will cause this...

You can flash the phone to change the nv settings and allow use of it on a prepaid network such as Cricket or Metro PCS There are other networks as well such as Ting (I think you don't even need to flash to use Ting) https://ting.com/byod
I was wanting it on StraightTalk. I've seen people have this done while searching but I cannot find out how to do it. I'd like to do this without having to sodder anything.

Might need to be flashed back depending on how the NV items are held. I flashed an HTC evo once to cricket and when I did a hard reset the flash went away. You can try a factory reset through recovery.
But first I would check the esn to see if it will even be accepted on sprint. A lot of times phones get flashed because they have a bad esn with sprint..
check it here.
http://swappa.com/esn
Thanks for the reply. I purchased the phone via swappa and it passes their ESN checks, I also called Sprint customer service and they also verified that the ESN is clean. However the chat representative claimed that it must still be active on some other carrier.
I have also used kitty wireless's meid check and it comes back as active_with_ppc and has what i assume is the old owners phone number. Any ideas? Is it as simple as flashing the correct stock rom/radio/prl and then going through the Sprint activation process?

Glad the ESN is good for you.
I think the issue you might have is that it is still active with another carrier. You can try to run through the process of flashing it using qpst. I think the settings for the other carrier are still there.
First try to flash the radio and prl and add it to your Sprint account. But like I mentioned, Sprint doesn't like when the phone is still active on any network, you may have to contact the buyer to remove the phone from their account.
Is the phone rooted? What ROM is on it? What does it list for Radio and PRL now?

Try to flash the ZVC radio and do a reset on the phone. Looks like you might need to flash some files using QPST. Also since you are on a stockish rom try to update the PRL within system updates. It might pick up the current Sprint PRL of 25019, that should help with activation. I don't know if it will pick it up since you are not on Sprint at the moment but it's worth a shot.
If that doesn't work, find a way to flash a newer Sprint PRL with QPST (I don't think you'll find 25019 on the net yet) then try to update it on the phone.
You might try some of these codes too to see if you can do some NV changes, seems like the one for network reset or clear OTA provision might do the trick, I stongly suggest you make a full backup including an EFS backup first before doing anything.

Looks like the phone is still registered on Page Plus, I had KittyWireless run an ESN check and the MEID came back registered to another number and the status is ACTIVE_ON_PPC. Looks like I'm going to have to return it unless I can get the original owner to cancel their Page Plus account.

Could anybody who has flashed their ls-970 to Cricket take a second out and tell me how they activated it on Cricket? I see services online that will flash my phone to Cricket for $10, but Cricket staff said there is no way to activate a phone without a sim card. So how did any of you sign up to Cricket with your flashed phone without a sim card if Cricket says it can not be done?
I have found serious issues after new update in oneplus 5t. My IMEI number is null, both the sims are not detecting, wifi doesn't turn ON. This happened when after getting an OTA update in oneplus 5t. After flashing the file, the device works as normal for 2 days then suddenly restarted then the issue has found. I approached their service centre last week, they told that we need to change the motherboard for solving it. I found similar issues with other phones too and they have solutions with it. But can't find the solution for oneplus 5t.
I DIDNT HAVE ANY BACKUP DUE TO I AM UNAWARE OF IT. M REALLY SORRY FOR THAT.
Can anyone please help me out...I m sitting on it for the past 2 months can't find any solution...Please help me out
So the problem is that no one can restore your IMEIs - if there's no backup then you'll have to go for the mainboard replacement, there is no other way...
Thats hard, but I think thats how it is - always backup your EFS partiton, that should always be the first thing you do, if you want to modify anything (Root, etc.).
