[Q] I747M - Telus - Won't connect to network - Weird - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hi everyone,
Weird issue with my telus locked S3. When searching for networks it only shows EXT, and nothing else. Is my phone hooped? I already tried a fresh factory restore to stock. Checked blacklist and its not black listed. My SIM works in my S4 just fine. Hallp?

Does your phone show the correct imei when dialling *#06# on the dialler?

hmm

great question. It does...but with a /11 after it.

That's fine. It's the first 15 digits that represent the IMEI.
Have you tried changing the network settings to wcdma only?

understood. I didn't, but i'm doing so now.
Changed to wcdma only, rebooted. Still insists that EXT is the only network and is unavailable.

Which bootloader and modem are on your phone? Do they match the ROM?

Well i reflashed I747MVLUFOB1, and the weird thing is i had to do a factory reset on the phone for it to give me the default setup (when i flashed it..it seemed like it didn't delete everything). Now at least its showing "bars" of service..but will only find the EXT network (and i do mean cellular network here).
Any other ideas?

Did you change any of the modem settings using the dialler?

On a side note, seems like it won't connect to telus, but it will connect to Fido (and will roam on rogers with my international SIM). IMEI is not on the national blacklist..maybe its not the phone?

I am experiencing the exact same problem as you My problems also started after I installed the I747MVLUFOB1 (BMC/Bell version) on my Bell locked phone. Mine was a little more complicated in that I had also lost my IMEI and I had to restore my IMEI. My IMEI is now restored, phone is not blacklisted but same issue of only having EXT as a network option. If you figure it out, please let me know how you fixed it! Thank you

Hmm very strange. Well i did check the IMEI several times (along with the person that brought it to me) and couldn't figure it out so i had to give it back unfixed. I didn't end up figuring out, but i did hear of another scenario..exactly the same with an S5 they had. Wonder if there's a lot more people with this issue out there?

This tutorial saved my phone! Luckily I had a friend with the same phone.

I suspect your NV data was corrupted during a flash aswell!

Do you have the right APN?
Is your original IMEI still there?

Baseband and model show up as unknown. not able to add APN.
If you dial *#06# do you get something started in 35... (don´t put the whole number here)?

That means that you lost your IMEI while flashing.
Do you have a backup of the EFS folder?
If not I think you have to flash stock Samsung rom with Odin, but it will be better if you ask in the rom thread.

[Q] Phone signal problems

I have got at&t unlocked phone and I haven't had any problem from above an year but I have been having signal problems from two weeks now. Messages come and go after hours, sometimes they are quick. It's like my phone is on it's own mood whether to send or not. When I try to check credits I get the error "Connection problem or inavlid MMI code". Sometimes my phone's carrier disappear too. Signals are all full. I tried porting into another carrier and found no difference at all.
I think it's related to IMEI because when I *#06# then a pop comes written "0" on it instead of showing IMEI code. Please help! Thanks!
For some reason, it looks like the folder containing your IMEI has been corrupted. Try to re-install the imei using NV writer.

Have you recently updated your rom or flashed anything? Maybe you could flash the modem files again and fix your problem?
When you go to about phone what does it say for baseband?

I think the problem occurred after I flashed leaked version of stock 4.3. Firmware was I747UCUEMJ2. I flashed CyanogenMod 10.2 hoping that it might fix the problem but it didn't made any difference.
I checked baseband version and surprisingly, it's I747UCUEMJ2. So, what do you think? Is that the problem? Also, how can I fix this? Last question, what if I restore IMEI etc then will it still be unlocked or I will need an at&t sim?

Restoring will not re-lock the phone. If your imei and baseband appear correct, I don't think you need to inject the imei.
You could use Odin to flash back to stock and see if the problem persists.

So the imei from the phone's keypad matches the imei on the phone's label?
Yes, it does.

Sorry to disturb but I have a question. Since carriers over here doesn't provide micro-sim so we have to cut out large sims and then ready to use. So, I did that but I also noticed that my friend who has S3 got smaller sim circuit and my sim's circuit covers almost whole sim. Maybe that could be the problem? Please answer so I can then contact carrier.

Samsung Note 2 (Sgh-i317m) connecting to unwanted network operators with roaming off.

Hey, So, I realized I posted a forum about this with an "anonymous" account.. And sorry about that.
Anyways, My issue is, my darn phone will drop the network, and decides to connect to a rogers or telus Network Operator instead of Bell (or just completely dropping the network entirely). I did the unlock hack through the original baseband, then updated to cyanogen 12.1 and installed the I317MVLUDNF3 modem, Same issues. I just dealt with it but am wanting to try to fix this. I recently moved to Resurrection Remix 6.0.1 (which, by the by, is amazing) and its gotten better reception, but same darn issue.
So, How do i go along to fix this? Any way through xposed or root or WHATEVER cause this makes the phone really unreliable.

It could be that these custom ROMs need the latest bootloader and modem to function properly.

I'm downloading the mvludnf4 modem, and i have the latest bootloader from 4.4.2.. So, lets see if this modem fixes it..
Any other ideas?
If it seems to work properly on a stock rom, maybe flash back a completely stock rom, flash twrp, and then a custom rom?

Sorry for the late reply. I flashed the nf4 modem and reception is better.. Battery life sucks but oh well. I think this is a hardware issue.. I'm getting around -90 to -110dbm and 0-7 asu MAX. Maybe my antenna is busted?
Maybe try flashing back to a completely stock rom instead of just flashing the modem?

Well.. I don't see how the ROM could have an impact with the signal strength but I'll give it a try. Anywhere i can find a completely stock rom? The one stop shop only has stock slightly modded. Unless that will work

And maybe the dialer unlock causes this? I could try getting it properly unlocked? Any insight on how carrier locks work?
I had an i317m that was locked to Telus running stock kk.
I used Odin to flash a stock 4.1.1 Samsung rom, sim unlocked the phone via the dialler menu, flashed back to the latest kk, pass the phone to a relative, and he has been using it for years on Rogers with no signal issues afaik. It may be possible that this method of unlocking causes a signal issue but I can't be sure.
In the thread that was linked, it looks like it could be a hardware problem.
Hmm.. Well I tore the phone apart and the antennas seem to be jn place.. The 4g antenna is alot smaller then the GT n7100's. Maybe that has something to do with it.. That or this phone has trouble with bell frequencies?

Then i am completely lost.. Something must be hardware related.
Not 100% sure but doesn't the phones imei number have to be registered on the network it's using. Maybe imei has something to do with it.
Just a copy and paste off the internet instead of linking to a website. I think imei is the problem.
What is IMEI?
Mobile phones, except the serial number have also IMEI number. IMEI — International Mobile Equipment Identity. IMEI — a common standard for all mobile devices, which is assigned to the phone at the time of manufacture it in the factory. It's the unique number, which is broadcasting to the carrier to authorize phone in the network. Structure of the IMEI is the same for all phones regardless of manufacturer. IMEI number is also used to track and block lost or stolen phones by the carrier, which further prevents to use of such devices. However, blocking IMEI in one carrier network have no effect in others networks.

Well.. If it was an imei issue wouldnt it be getting no signal at all since the phone can't register on the network?
Canadian carriers don't need the imei to be registered, only the SIM card.

Cannot connect to LTE (doesn't matter what rom i'm on)

SIM card is toast. I have had this exact thing happen to me. Just go into a VZW store and request a new one. Sim handshake needed for LTE connection only on VZW.

Contact your carrier or go in and tell them that it is not your number and that you are stuck on 2g they should be able to tell you how to fix it or if you go in they can fix it
I did contact my carrier, they cannot figure out what to do. Replaced the sim about 4 times, still no luck. I go into testing (secret code) and I am on 1x network @loeffler23

my phone's unlocked by default and there has to be a way to fix efs, not accessible by recovery? (what is efs)
It holds the imei and other radio proprietary info not sure what partition that data is actually in on this device. I think the efs data is no longer in /efs
Twrp used to have a option for efs backup with the data system backup and restore options

Question LE 2127 no signal

Need help here! I forgot to backup my oneplus 9 pro LE2127 when I tried to root my phone using TWRP,and I installed TWRP in my phone's boot partition which wiped out all data in that partition. I used TWRP side loaded Global ROM to recover my phone but the phone doesn't have any signal with sim card in. Used MSM tool backe to T-Mobile 11.2.5.5 and still same problem, sim card can be read but no signal. Flashed T-Mobile modem but modem b failed, it says no such partition.
Bought this phone from third party. Any suggestion is appreciated.
