Hi there. I have a note 2 sgh-t889 and the problem is as follows. rooteo recently and he was lost imei so I ran out of network registration. ime can once again but still I do not register on the network and the signal bar, stays in a circle. baseband has its imei. I'm running 4.3 stockrom UCMK7. thank you for your help this solution.
Did you fix the IMEI? "ime once again" doesn't make sense and the baseband is separate. If you screwed up your IMEI you'll have to look for help elsewhere.
no. is the same imei repair that is behind the phone on the label. but still no signal and no network registred

I have a canadian based S3 I747 and its unlocked (any sim card i insert it wont ask for the unlock code). However, no matter what i do... (root, update a non carrier rom, carrier rom, reset settings, install cwm radios posted in xda) the phone will not get any signal strength.
The imei is showing... however the signal strength is 0dBm 99 asu... I cant even dial 911 it will say mobile network not available..
Any solution to this will be grately appreciated... i will gladly buy you a coffee or a ham burger...
Thanks,
How did you unlock your device?
Does this happen even with the stock ROM and whatever SIM you were using before you unlocked the device?
Do you have an appropriate network operator set in Settings -> Other -> Mobile network settings -> Network operators (automatic might work in this case), and a matching APN?
Just trying to get a sense of what might be causing this...
Maybe a hardware issue?

I bought this phone from someone and stupid me didnt check at the time... i have tried every sim there is present in toronto, canada... and still no luck...

It shows the apns automatically once i put the sim card... like Bell or Rogers settings are shown in APN automatically....which means it reads the sim cards but doesnt register on any network... no bars... just a do not enter like symbol.....

How to find that out...
One thing that i have noticed is that the serial number from the phone behind the back is not the same as the serial number shown in status settings of the phone....
i really would not know it's not really my area i think smelenchuk might help better. Sorry i couldn't be more help.

Sorry please ingnore this as the serial number was changed when i installed cyanogenmod... when i put stock rom the serial number is back to thr same as the sticker behind the phone...
I'm not really an expert on this either, but I'm going to guess one of two things is going on:
1) The phone isn't as unlocked as advertised - perhaps something went wrong with the unlocking process and shot the modem firmware. You'd need to figure out what network the phone was originally on to figure that one out, though. (Which reminds me - what baseband is your phone running right now? You might try something else from here - and make really sure you're using a Canadian baseband!)
2) Something was wrong with the phone long before it was ever sold to you, be it bad hardware, a bad IMEI (stolen phone?), etc. - the whole description of "bought my phone from someone" just sounds suspicious to me when you put it like that.
Honestly, I hope it's a modem firmware issue (I think if it was something to do with the IMEI and the like, you wouldn't be seeing those strange signal strength numbers).
EDIT: Here's a fun fact: when I unthinkingly flashed the broken CM10.1 12/28 build this morning (broken in that it refuses to communicate with the baseband), I saw exactly the same strange signal strength numbers. This leads me to believe that you are indeed facing a trashed baseband and/or an empty IMEI number, so check those out!

Have a free thanks courtesy of my fat index finger...
Is anyone else on your carrier having slow dialing? It almost sounds like it is carrier based due to the fact that you can sometimes actually make calls. Who is your carrier?
Hastily spouted for your befuddlement
First of all, thank you, I call others on the telephone, such as friends and colleagues, call success rarely, people call me, success is rare, most of the time
That is not in the server, our operator is China Mobile
sters!
Im john from the philippines and i was given this at&t Note 2 i317 by my sister that came from the us. I did a procedure which is doing the network unlock and i have no problems doing it and as expected, i managed to remove the sim lock on my phone and the phone recognized the sim card.
HOWEVER, after doing so, i lost my reception/signal and i always have this circle with line in between wherever i go. Regardless what sim card/chip im using, still showing the same icon. I have another phone (galaxy mini) and sim works fine.
I did my research and undergo flashing multiple roms (stock and custom) in Odin and Custom recovery, did clean wipe (factory reset, cache, system, data, dalvik), unroot and root multiple times, flashed Modems (from oldest to newest please see the attachments) to update baseband, did the "ping" and change the radio optio in hidden keys in dial pad to On/Off (vise versa), redo the FREE network unlock multiple times, followed the "Not Registered On Network" process, but sadly i still get the depressing same result.
BTW, the radio/modem hardware is working. There are times that the signal goes to 2 bars and has 4G connection. My wife is using the same carrier as mine and has full bars but mine is 0.
I am soo depressed right now and im about to throw this phone to the wall already. I've lost a lot of time on this to the point that my wife is already getting mad at me.
I desperately need your expert advice. I cannot send this phone to at&t since i am from the Philippines and it was only given to me.
I've attached screen shots for ur reference. I am using ezKat 4.4.2 Beta2 custom rom.
My email addresses are [email protected] / [email protected].
also, my phone can detect my simcard and the carrier is SMART TELECOM
Looking forward for your expert advice soon.

seeks qcn.bak of i317 and restores THROUGH QPST. This T reactive bands
Same here
Main problem is my S4 give error "Not registered on network"
Some times call works. but after leaving 10 to 15 mints when I try to call it show error "Not registered on network"
I read many help pages saying that IMEI can be null or blocked. I checked IMEI by *#06#, Mobile is showing IMEI but other than back on striker. While using mobile is showing M919 model, inside T mobile account aaps but on back stiker under battery is is showing mobile as GT I9500.
I decided to master rest mobile but confused
1. If I reset mobile, will my mobile software go back to GT I9500 or it will remain M919?
2. IMEI will change by master reset or will be same?
3. Is it possible that after changing IMEI back to original, mobile stop work in my country?
My mobile is Korean
Kindly Advice.
Resetting it will not change the software. You need to flash original I9500 firmware.

Can flashing original I9500 framwre solve network problem
Can flashing original I9500 framwre solve network problem. It loose connection every time.
Network software say you have 23 % GSM signal. but on dialing number error comes "Network not registered"
Some time it doesnt gave error but call doest not send to dailed number or received from him.
Please advice how to solve that network problem?
Thanks
What is your baseband and build number in settings? When you get a not registered on network message it usually means the device is blocked by the carrier, which is odd in this case

It looks like the device Is M919 not GT-i9500
The device is not locked, otherwise it would ask for unlock code. I would either take it to your carrier and see if they can look into the problem and maybe they will have a solution, or you could also try to change the imei number, that may work because of the error message that you receive, which usually means the device is blocked from service, not locked. Changing the imei number may be illegal in your country and no methods for doing so will be discussed here

Thank you for reply Bro.
I found little solution
Bro this is not IMEI or block. see below and further advice
1.
Yesterday I changed rom From kitkat to FlexOS. and installed app "" Network Signal Info"
in this Rom I have choose network "2G", so when i lose connection, and i came to open area or out of room it automatic connect to GSM network. Kitkat was not auto connecting even if 2g only was selected. but FLex rom it good.
2.
Inside room network signal info app show signal strength less than -70 as "-80, -90, -100" "Signal % from 32 to 55" and ASU is from 12 to 18 then network loses on mobile, no send receive call. But when I go out of room signal goto green , -70 -60 -50. ASU go to 20 , 22, 24. then FlexOS it self connect. and i receive and send call.
Can it be antenna problem? or if i install app that tweak or boost signal so that either i tweak and make call on same -80, -90 signal strength or i make call on boosted signals by app.
Thank and please advice. I think i am very near to solution.
Boot into download mode to see what model # is shown on the screen.
Hi guys can you please help me with this?
I bought my note 5 off craigslist and it was currently on G920AUCU1AOJ1
This security notice wouldn't stop notifying me ect common error I guess when they first came out. Solved by getting app disabler.
I really wanted to get the marshmallow update, I tried OTA says it was fully updated.
I then flashed it too N920AUCU2APB2 Then I noticed it was saying emergency calls only when I tried to call someone. I just continued to flashing to marshmallow.
Now I can't even find a downgrade firmware back to my original state to get the phone to even work again! everything else works but when I looked in to about my phone
SIM card status it says Network Unknown, signal strength -113 dBm 0 asu. Mobile network UMTS, Service state out of service, Roaming Not roaming, mobile network state Disconnected.
I believe the guy I bought it from knew all this and that's why he took it back to a stock firmware.
Can someone please help me out with this? I can't even find the stockware to take my phone back! Either I would and the links broken or its for a different carrier.
