Signal Loss - 1 bar - No Sevice I747m - Cant receive calls - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hi,
I have a fido I747m I baught off someone and tried before buying it to see if my rogers and Pc mobile sim works. Did placed call and was ok. After placing a few calls I was having trouble getting them to go through. Only 10-30% of calls go through. I noticed the signal strength is one bar and increase to full when placing the call and if it does quickly the call will go through if there is a delay the call wont go through. Now to receive calls I cant unlesss by chance I have more than one bar when someone is trying to call me so less than 1% of calls I receive. I've wiped and reflashed the fido rom bell rom and the new pc mobile rom the result is the same. Turned on/off airplane mode to get to work for less than a minute. Ive rooted the phone and modified to downgrade to 4.1.2 still no luck. Some people are telling it may have been unlocked badly. What can I do. I want to try to flash EFS but Im seeing I need to jtag which I dont have. Please let me know what I can do or if there is nothing that can be done.
EMEI OK

Your NV file might be damaged/corrupted, which seems to be quite frequent with unlocking. You could copy one from another phone with nv-reader-write.
Before going that route though, you can try flashing another modem. I believe the latest one for Canadian users is ND3.

That's what I actually did and worked. I didn't even modify the nv file and change the imei on the file. That easy it kept its own imei.
I tried flashing radio before and didn't work.

Is it normal I didnt have to change the imei number of the nv file.

Never try to "change" the imei. Unless meeting very specific criteria that is illegal.
Didn't you just say its working now though? Or did I misunderstand? Imo, messing with NV data should always be a last resort. If something goes wrong you can cause irreparable damage to the device. Plus ime, many people find they don't even need to go this route and just flashing the stock firmware often solves the problem.

[Q] No Network Access on Galaxy Note 2 ATT

Hello my name is Stanley, I recently bought a Galaxy Note 2, I'm from the Dominican Republic so I'm using Claro Dominicana, which uses the same baseband as AT&T, basically instead of the signal bar, I get a circle with a straight line on it, I don't have data, I can't make calls, I can't send sms, when I try to call I get no network access message, I believe it does recognize sim because I don't get any type of error when my cellphone boots up, when I bought this cellphone it wasn't rooted, so I decided to root it and flash a rom, I'm having same issues.
Can you guys help me out please? I already have my APN information but it's not helping, I've tried flashing roms and it's not helping, I really don't know what to do, when I first bought it, I tried my sim out and it did have internet, I decided to do a factory reset through settings menu and after that I haven't been able to get any type of signal, I would deeply appreciate your help guys, I'm getting kind of desperate here.
No signal bars means no modem or a sim card for a dead account. Did you pay for any airtime?

Did you try the free network unlock?
Might just not be unlocked

I did try it, I'm pretty sure is unlocked because it was just working before factory reset, I guess I can try to do it again, but I'm pretty sure is unlocked.
I tried several roms and modems and nothing worked, the last thing I did was going back to stock through Odin, but I still get same circle with the line on it, a stop sign, right now I'm on 4.1.1 stock..

i don't know if this might be an issues or not, but check your IMEI. T-Mobile webpage has a method to confirm if it been blocked or not.
http://www.t-mobile.com
As of August 8th of 2013, they've re-designed their webpage.
http://www.t-mobile.com/bring-your-own-phone.html
following that link, scroll down until you see this: "Don’t see your device?" and under that, a search box. click on the link below that search box. it'll bring up a screen within the webpage. input the IMEI from your phone (*#06#) and avoid adding "/ ##" as those aren't part of the IMEI. If it report as stolen, chances are, they probably blocked it. If not, then maybe your provider doesn't support the phone itself. you might have to call customer service from your area.

I couldn't find information about my imei using that webpage, it wasn't able to locate it, I used this webpage which said is clean http://swappa.com/esn I don't know if that page is good, but it says it's clean and ready for activation.
Try a friends sim card to rule that out
If the phone worked on your network before you rooted and flashed the new rom, then I imagine you must have flashed an incompatible modem. If you flashed stock back via Odin and that didn't fix it, I'm scratching my head. Try stock again. Then remove and insert the sim or toggle airplane mode. If it worked before, stock should fix it.

Hello guys, in this case it was actually a hardware problem it seems that the internal antenna of the cellphone which receives the network signal was damaged, I'm already getting it replaced, I'll let you guys know the results.

Do you know what was damaged. Is it the wire connecting the USB flex or is it the antenna built into the back housing?

[Q] Very bad service, not able to update, doesn't recognize other simcards

Something really weird is going on with my At&t galaxy s3. I'm new to this forum so I'll just explain what I'm experiencing and do my best to work through it will all of you. This phone got rooted by someone else and when I got it, the rooted program was in chinese and was acting all weird and wasn't getting good reception, although it was before it was rooted. I flashed it back to normal and it's acting very curious. It will receive an At&t simcard but the service bars will go from 1 bar to 4g to Edge to 1 bar all in a matter of 20 seconds or so and doesn't seem to work. It will occasionally work to send messages, make calls, but it seems like it can't ever receive calls. I checked and the IMEI number is still the same. Also, I had originally tried to unlock it to another carrier and when I put in different simcards (From other carriers such as verizon) the service bars don't show up, instead, all it shows is a cancel sign and doesn't ask for an activation code or anything. I'm honestly not sure what to do here, I thought I had broken the simcard reader and replaced that, but that made no difference. I'd greatly appreciate any help. Thanks!

Unlock is supposed to be permanent so it's odd that you lost it.
Now as for your problem, a lot of people are getting this issue lately, where unlocking damages their nv file. The solution can be found here: http://forum.xda-developers.com/showpost.php?p=43842387

Thanks for your quick response I have been looking for a long time and never saw this issue before. I'm not sure where I'll be able to find a replacement nv file...but i'll see if anyone I know has a galaxy s3 from at&t. Maybe once I do this the unlock issue won't be messed up anymore.

LG LS-980 Sprint to NET10 driving me crazy!!!!!

Hello,
First, let me express my deepest thanks in advance for those of you who may be of assistance. I have visited this site many times over the years when I needed to find the answers to smartphone related issues (mostly rooting..etc). I have usually found the information that I needed via reading posts and trial and error; however, I am having a problem that I cannot find the answer to and it is frustrating the crap out of me.
So, here goes:
I bought a LG LS980 off of Ebay. It was locked to Sprint and I had a friend of mine root it (since I couldn't figure it out and it ended up being that the firmware had to be downgraded since a patch was bumped to it) and unlocked (or so i was told, but I do not know how to find out). It is currently running Cyanogenmod 12.1. I wanted to use my old phone's SIM and pop it into my new phone so that I could enjoy it (the old phone was a Nexus and ran hella slow). So, anyway.... I contacted NET10 customer support since that is my carrier and explained what I wanted to do. They let me know that as long as it is unlocked that I would be able to just swap the SIM into the new phone and should be good to go. They checked my IMEI and said that the phone was, indeed, compatible and as long as it is unlocked it should just be a matter of a simple ROM swap. Not the case. I put the SIM in and booted it up. It went from No Service to saying "Sprint" on the upper left hand corner. I try to make a call and it states that, "The code or number that I am dialing is incorrect, please try the code or number again". I looked this up on the internet and didn't find a focused answer. I talked to my friend and he stated that I may have to set up a new APN profile.
I have checked the APN settings on it and all of the APN profiles have the prefix "Verizon". I used this mini tutorial at http://forums.androidcentral.com/goo...-settings.html along with the NET10 settings to try and make a profile. Both of their workarounds don't seem to work. I can enter about half of the information and then either click BACK or SAVE and then the profile is gone. I am not sure this is the reason that my phone is not working, but I thought I would give it a try. I have also tried to use this tutorial: http://forum.xda-developers.com/showthread.php?t=2798566 as a loose guide, TWRP installed. Keep in mind that I believe that my firmware was rolled back to ZVE. and not ZVD. When I have tried to edit the build.prop values at the tutorial states it does not save. Also, there are two lines that are not even in my build.prop (ro.build.target_operator and persist.service.crash.enable). When I have tried to edit or add it adds them but does not save and definitely does not persist through reboot. I feel as if I am close to getting the phone to work, but I am unsure where to go from here. I really do NOT want to have to go back to a stock ROM and all of that because....well.... my friend did the rooting and installing of cyanogenmod and I don't want to risk undoing all of his work and having to pay $ to have it done all over again (I have rooted phones..etc, but this G2 was a MOFO because of the firmware patch for me). NET10 CS and TS was of no help and they gave me a ticket number (and to tell you the truth the are outsourced and I can't understand what their reps are saying). So, does anyone have any advice or threads that I can look at? Like I said, I feel as if it is close, but no matter what number I call it says that recording. I get no incoming calls (although it rings when listening to the incoming calling phone's speaker). I am also unable to send or receive SMS or MMS messages. Any help would be greatly appreciated. I am not the most technically savvy person, but I can answer your questions to the best of my ability and I am good at following directions. (I have about 5-6 phone root/ROMS under my belt and even 2-3 SPRINT to NET10 activations, but this one is just perplexing the crap out of me) . Could it be that the phone is not unlocked???? How do I check this??? Is there a way??? When I put in the NET10 SIM it never asked me for an unlock code so I am assuming that my friend unlocked it? I have also tried "Turn the phone ON and type 2945#801# If nothing happens, type 2945#802# or 2945#*803#" and no hidden menu appears asking for an unlock code.

You can unlock your Sprint phone for GSM but you can't activate it to Verizon or its MVNOs.

M9 "Randomly" Rejecting Calls

Hi there.
My M9 has a strange problem where it rejects phone calls on a seemingly random basis. When I try to call the phone from a landline or another mobile it shows no sign that there's an incoming call. The phone making the call hears a ringing tone twice, and then only a beeping (like an engaged tone but with one beep longer than the other). The odd part is that it doesn't always happen. I get the occasional cold call come through, and sometimes people phoning me can get through, but at other times they can't. It seems consistent that when I'm at home in the evenings it rejects all calls. I'm sitting at home now and if I try to phone from a landline or mobile it won't get through yet the phone is showing full signal and can make calls. I've tried with WiFi and mobile data on and off and rebooting the phone to no avail. SMS messages come through fine all the time.
I've contacted my network (Virgin mobile UK) and they've issued a replacement SIM - same problem. I've tried the SIM in a Nokia and it seems to work perfectly, so I've come to the conclusion it must be the M9 causing this.
To start with I was on the stock HTC Android, and I've not got any auto-reject settings turned on (that I can see). To try and solve this I've done a factory reset via the phone, and when that didn't work I tried doing a complete wipe and installing TWRP recovery and ViperOneM9. It still rejects calls!
Anyone got any ideas? I've tried searching for this but all the posts seem to be about setting up auto rejects, or not receiving any calls at all. Are there any logs I could look at to see if the M9 is getting the call but then rejecting it without my knowledge? Any hints here would be appreciated!
TIA
Flash the stock firmware via SD card method. It seems like a cliché but it really solves most problems both software and hardware. If it doesn't then you know you have bigger issues.
I'd place a bet that you have a rogue app abusing it's call permissions but it'd take ages to find it.

Thank you. I started doing that but had some problems, so in the end I bought a new phone, and lo and behold I had the same problem as I had with the HTC, and that was when the phone was fresh out of the box before I'd installed any apps.
After a LOT of playing around with settings, I've now figured out that if I have 4G turned on when I'm at home then all calls are rejected, even if WiFi is also turned on. Forcing the phone to use 3G when I'm at home means I get calls, and if I have 4G turned on when I'm at work I get calls OK. I guess the test with the Nokia worked OK as it wasn't a 4G phone.
After repeated calls to Virgin they've finally admitted that there's a fault on the phone mast close to my house, and by the sounds of it they have a lot of open tickets for that mast. As they use EE's network they say they can't do anything until EE pull their finger out, but as I've had the issue for months I bet it won't be anytime soon. For now I'll have to switch to 4G manually whenever I'm away from home and try to remember to put it back to 3G when I get back. Not ideal but at least I know what the problem is now!
Thanks for your suggestion, even though it wouldn't have worked in this case.
