It happened after I flash my phone with cyanogenmod ROM, i flashed a couple of google apps and a custom kernel. I THINK when i clicked a certain CPU speed in overclocking, it kinda stuck and restarted and had no signal at all... I flashed it again a couple of times even the beta cyanogenmod and dardroidXD, factory reset, wipe data, cache, remove battery. i flashed it with the original firmware with different version but still no avail.. Do you have any idea to solve my problem?

Flash a factory ROM. But this isn't a "Bell" forum (assuming bell.ca).
A safe thing to do is to install Samsung Kies and use "Emergency Firmware Recovery" to re-flash factory stock. That will return you to stock and hopefully repair your wifi.
You can also flash a no-wipe factory ROM that corresponds to the specific build on your device.

Thank you very much for your advice.
would you by any chance know of a no-wipe ROM build for an SGH-i337M on BELL from Canada? That would help out a lot!

[Q] 3G not working at all on SGS3

Hi everyone !
So i have this i9300 rooted on custom rom revolutionary (and i wonder if that itself is the problem) and 3G just won't work. I don't get the "H" nor "E" nor "3G" icon when enabling data, it's just frustrating. I have tried all tips i found on the net : resetting apn, turning airplane mode on and off, taking off battery etc ... i even put dad's card with which he uses 3G without problems, configured apn and enabled data and roaming, but nothing, not even a sign of 3G. How can i make it work ? I can give whatever infos you ask but please give instructions as i'm a noob :laugh:
any help would be welcome ! thank youuu
Follow the guide in general forum to flash back to full stock firmware. Download the right firmware for your country from sammobile.com
Factory reset after flashing in recovery.

Samsung Galaxy Alpha G850F - Official Android 5.0.2 - Flight Mode Problem !!!

Hello everyone,
I'm new here and I need your help about an issue that I'm facing at the moment.
I got a Samsung Galaxy Alpha G850F that it is in 100% official state. I haven't touched its rom, bootloader, kernel, root access or anything. It is completely stock.
A few days ago I received the OTA Update for Android 5.0.2 Lollipop. I downloaded it and installed it. Then I did a hard reset and started to reinstall my apps and stuff from zero. But I noticed an issue.
I did this. I enabled flight mode and turned off the phone completely. Then, on the next startup if you turn flight mode off it will NOT ask for SIM PIN (while it should) , it will find signal but it will be unregistered to the mobile network! So you can turn flight mode off but the phone will be in "Emergency Calls Only" state and you will not be able to make phone calls, use mobile internet or anything. The only way to fix this is restart the phone BUT with flight mode disabled.
I never had this issue with the previous KitKat firmware (I could do this easily with KitKat, when I turned the phone on and disabled flight mode it would ask me for SIM PIN and then it would be ok). So it seems like you can't start the phone on flight mode anymore. Flight mode works good in general, u can turn it on and off while the phone is on BUT if you enable flight mode and then power it off then you will have no network on next power on.
Anyone else with stock Galaxy Alpha and official 5.0.2 experiencing this ??
Any ideas?
Thanks in advance.
SOLVED!
So problem got solved by itself! I tried to do this today and it worked fine as it should. I haven't changed anything. I don't have a clue what caused it. Maybe it was network related?
Thanks anyway!
Please help me, I have a galaxy alpha g850f fingerprint sensor does not work Is there a solution to this problem

Not registered on network

Good day guys.
I have a problem that I think is very common, however I haven't found a solution yet. I recently update my S6 edge (925I - latam) via odin to Nougat, everything was cool but I can't do or receive both calls or sms. I have cellular signal, however there is not registered with the network carrier.
I already flash modem.bin from older firmwares and do not work. Sometimes I loose cellular connection or stay the same, with signal but not registered. I tried other possible solutions like airplane mode and reboot, flashing roms, connect only via 2G or 3G, nothing have worked. My sim is not corrupted and the imei is just fine, without report or related.
I hope you can help me. Thank you very much.

Same issue for me.
Tried:
OTA update
Odin update - installing new stock firmware (with different software version)
Factory reset
Installing TWRP + LinageOS beta
Replacing the sim slot in a service
Nothing worked. Anybody?
Look in settings > status
Do you guys have an IMEI?
This happend to me 2-3 times last 30 days... sometimes I have signal but not registred on network, sometimes there's even no signal, etc...
I also tried several things to resolve the problem...flashing modem, reset dialer, changing network mode, enabling airpalne mode, another SIM card, etc... For the 1st time, flashing modem helped... but 2 days ago when this happened again flashing modem did not help...then I tried changing network mode and I got signal again... last night it also lost signal and today I changed network mode to 4g/3g/2g auto and it got signal again, then switched back to 2g and it's fine till now...
Hope this will not repeat....if does, coulb be very annoying thing...

Bro, download some older firmware from the one you have from sammobile and exctract it...there you'll find modem.bin
At last, I couldn't fix my s6...so I sold it...then the guy who bought it needed to write some chip to motherboard and he got it working again...
