困惑： My T-Mobile note 2 is initially network lock, unlock steps with SPT, so, 1 SPT mode, 2 reset the EFS file, 3 engineering model. The signal is now the norm, IMEI is normal, but the phone dialing Is very slow, Always stay in the dial-up interface, Sometimes the dialing success, But most of the time dial failed,I restored the original T-Mobile firmware, but still the same, baseband I changed, still the same, I don't have a backup EFS, what is the problem? What should I do? Really be indebted forever

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

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!

You could fix your s3 ?? I have the same problem
I have tried dozens of solutions, NOTHING seems to work, I cannot get data, on any single ROM, and build any where, any how, I unrooted it, put stock firmware on, still nothing, I go to my mobile networks, and it says WCDMA preferred, I change it to LTE/GSM/CDMA, or any other option, I have no service at all, only emergency calls!! Then in about 2 minutes, it switches back to WDCMA prefered, I talked with Bell, for my i747m, they said nothing is wrong with my data! I have tried 2 different modems, still nothing, I have no friggen clue what is going on, it all started about a week ago, I just woke up with no data, if anyone knows anything, please let me know, I need data for work and school, this **** is killing me!
Did you set up your APN correctly?

I didn't really do anything, I put my data on hold (Called bell and told them to do so) and now I took the data block off and now I can't receive anymore data, tried many ROMS, many APN settings, many modems , nothing.....
EDIT: Yes I called them 3 times and they confirmed that the data block has indeed been removed, all 3 said it would be instant, I took out my SIM car and everything.
Flash to stock, same as preparing for a warranty return. Verify you have an IMEI number. Replace your Sim card. If still no good, warranty return.

I might get a new SIM card, they are relatively cheap, I did flash to stock, everything brand new (for warranty return) I do have an IMEI number, I have been starting to lose signal every now and then, randomly, I just have no bars, outside, in rooms, at work, everywhere, and what's weird is that I lose all signal, when I turn on LTE/GSM/WCDMA
Have you checked to see if the IMEI is gone?
so I have the galaxy i747 on att unlocked.
a few weeks ago it bricked itself trying to over the air update. I couldn't fix it so I had it jtagged and it came back. I also paid for an imei repair.
everything was fine, I could make calls and stuff but eventually lost signal.
I sent it back as I ended up bricking it trying to restore to stock rom (it was on philz touchwiz)
he fixed it, said the network problem was due to my simtray.
I replaced the simtray today, I had full signal but when I tried to make calls there was no dial tone and ive lost signal again, this time its running a hyperdrive rom. my simcard is TESCO which shares a network with O2.
it picks up the simcard and stuff im just not getting any signal, when I try to register on the network it says unable to connect.
if anyone could please help me with this I would really appreciate it! alex

I would check your IMEI/baseband. Make sure they're correct.
Also, could check your APNs.

ive tried both those, the weird thing is I get signal and can make a call and receive texts when doing a gps check. something is blocking it but im unsure what.
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.
No network signal on unlocked Note 2 AT&T
Is there no one to help resolve this issue? I've been having exact same issues for sometime now on my AT&T Note 2 I317. Please any useful response will be appreciated. Thanks.

seeks qcn.bak of i317 and restores THROUGH QPST. This T reactive bands
Same here
So I rooted my J2 (SM J250F) and one of the apps I installed is a mac address changer. I was using it to get around a 30 minute limit at airport wifi. Well I think it messed up the efs partition because after using that app I cannot connect to mobile, most of the time it will not even get a signal. The IMEI, serial # of device and model name match the sticker under the battery.
I did not backup the efs partition and I have used odin several times to get back to stock, tried kies program which told me to try smart switch, which I then had to use a older version. Smart Switch keeps saying to check serial and model name over and over even though its correct. I am a little unsure how to proceed from here. I just created the pit file and backed it up along with the corrupted (I assume) efs partition.
Anyone know what to try? I'm not worried about breaking it more as its already a expensive calculator. lol I feel like using odin and start ticking boxes under options even though I don't quite understand the implications. I read that samsung kies/smart switch -restore/initialize can put back factory settings that are unique to your phone, however that option is not working.
Edit: update, I think I may have been in a area with no service. I was at Chicago O'hare and connected to att when I had service, then in Green Bay where I had no service (tried sim cards for both att and tmobile) Now I am on the border with Canada and the phone has service on Rogers. with the att sim card. I guess the J2 is a poor international phone and I need to research the carriers bands a little more.
