[Q] i317m sim not registered after 4.3 update.

Hey guys been stressing for 3 days with my wife's phone. She got the ota to 4.3 and everything seemed fine
until she rebooted the phone. Now any sim i put in says unregistered sim and cant connect. Strange thing is it says there is new voice mail which to me means it is connecting to the network. I've reverted back to factory 4.11 and same problem. But it's still on 4.3 bootloader and Knox is tripped. And since there is no way to revert i317m bootloader like 317 i can't fully go back. I did the free sim unlock and wonder if that could be the problem with it reading the sim cards? Is it like a code unlock? She's freaking and I'm so stressed. Any way to test if phone is reading sim? I'm sure this is software related because it doesn't say no sim and tells me there is new voice mail.

Not sure it would help but I would try reapplying the 4.3 update via Odin. You can find the update on Sammobile.

ok so I did the update again but threw odin this time and still not working. but there is a difference, when I try to select my network from the list it site for a while and says unable to connect, try again later.

Tried to flash other modems and it fails in Oden and phone says unsupported. I think Knox is stopping me from changing modem file. Anyone know how I can get passed Knox?

[Q] Newly unlocked s3

Hi everyone. I just want to ask a question about my s3. So here is the scenario:
I brought my s3 locked to rogers to a CP technician and asked him if he could unlock my s3, he then told me that he can unlock it even though it is in 4.3 firmware. I don't know what he did but the only thing that I know is that he upgraded my s3 to 4.4.2 and he also rooted it. When he gave it back to me, I can already use any sim card so I guess that the unlocking is successful. The problem occured when I got home, my phone says it is in emergency calls only so i tried to toggle airplane mode on/off if it would fix the problem and it fixed it, I can call my phone again but then after 30 secs of toggling airplane mode to off, it would eventually cant receive or make calls or text. But when i toggle airplane mode on/off again, it can receive or make calls and texts but after 30 secs the problem occurs again. I go back to the CP technician to ask him what's happening but when I'm in their area, the phone works like a charm. I don't even need to toggle airplane mode on/off. And it can also receive or make calls/texts in their area. But when I go back to our place the problem occurs again.
BTW, my ImEI is still the same at the back of the phone if this info is needed.
Thank you everyone and i hope my problem will be solved.

Can you change network modes on the phone?

Yes I can change network modes, and everytime I change, the problem occurs too. It'll work for 30 secs then after 30 secs I cant receive and send text/calls.

Did it do this before unlocking?

What baseband is on your phone?

it is just after unlocking because i've never used it yet with its rogers sim card, this phone was just given to me by my aunt and I live in different country. Before unlocking it does not have this kind of problem, my aunt can use it with its original rogers sim card fine.
Btw. The baseband of my phone is I747MVLUNF2

Is the bootloader the same?
There is updated firmware on sammobile.com for the i747m.

the bootloader is still the same. If updated my firmware, i think my phone won't be unlocked already.

Once the phone is unlocked, it will remain permanently unlocked.

Thank you for the reply mate, I will try to update my phone, should I still use the rogers i747m rom?
another question, can i try to install other roms like cyanogenmod or other custom roms, will it still be unlocked? do you have any suggestion for a good rom? Thanks mate. cheers

You can flash a stock Rogers ROM. After that, you can install Philz Touch recovery, backup your current ROM, flash another a custom ROM (I like Liquidsmooth), and try it out. If you want to go back to stock, boot into recovery, and restore your backup.

Hi sir, I found out that I'm on the latest firmware already, it's 4.4.2 already so i don't need to get it from sammobile already, will i just skip the flashing on stock rogers rom step and proceed already in installing Philz Touch recovery to install a new rom. Thank you so much sir.

Connect via wifi and install any ota updates. Then install philz and a custom rom. You may also need to install gapps if they are not included in the rom.

H815 can't make / receive calls but sms / data works great?

It's a UK vodafone G4 which I got unlocked and was using my O2 sim without issues. I ported the O2 number to iD Mobile (three network) and can use SMS as well as mobile data but calling doesn't work at all.
I put a Three sim in and it's exactly the same issue. The iD sim works fine in other phones. Other sim cards work fine in the G4. It's just iD and Three sims that won't make or receive calls.
I since used LGUP to install a kdz file (V20c-234-15) in the hope anything vodafone will be removed but that didn't make any difference. In the phone Settings if I check Network Status it shows the iD connections, in Status it shows Unknown Phone Number, in Network Mode it displays 2G/3G/4G, APN shows all correct iD settings. If I search for Available Networks it displays all the usual UK networks and only lets me select iD network.
Customer service said wait a few more days after porting and suggested a faulty sim (yet works in other phones) but after both iD and Three sims showing the same issue I've not much hope in their suggestions.
I know others that bought the vodafone G4 and unlocked it for Three haven't had any issues. I only found 1 other post online that has the exact same issue as me but their post hasn't updated since last month.
I don't know what to try. Other sims work, just not iD/Three. Any ideas for me to try?

I've since tried another kdz file for lollipop as I know for sure the sim worked before the number was ported before the phone was upgraded to MM.
Still doesn't work for calls, only data and SMS.
Can anyone offer more suggestions to try?

This is a weird problem maybe your problem is modem or wrong kdz file. Downlaod right file and flash again and be sure that you click refrush that is makes wipe in LGUP.(I use LGUP)

Thanks,
I had this problem with stock rom too though. I only started trying more kdz files in the hope that might work. Issue started the moment my number ported from O2 to iD Mobile.
Wierdly the phone doesn't like Three network sims either now and those worked fine before the number port happened.
Am really confused

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.

Yesterday updated my device to the new "stable" 12.0.0.0 . And since then I have not cellular signal.
Tried network reset
Tried fix the APN.
Nothing helps

May be this can help:
I had the same problem abroad. Check settings with your provider are right.
I couldn't find wifi, because my settings using phone abroad where out.
