[Q] Updated to MKF & Now Unable to Get Mobile Internet

I recently updated to the MKF update on my i9505 BTU. Prior to this my mobile internet was fine. Since the update I am unable to get any mobile internet. All settings are checked to ensure I should be, the APN hasn't been deleted and I've got no idea why this should have changed anything. I'm on the EE mobile network.
Any ideas?

Just did it and now I have 1 bar of H so i suppose better than nothing. Weird that even though it uses the same APN settings that happens.
Any reason why?

Hi man. People keeps telling you to install new modem, kernel etc...but i think you have corrupted EFS folder.
I hope you backup your EFS folder before flashing ANY rom because, otherwise you will have to go to some repair shop.

Well, I don't understand a lot, but I think you could check if you didn't lost your IMEI. Go on Settings > About Device > Status and check if your IMEI still there.
If it is, I don't know what could be. You could try flash another modem or restore a backup (if you have one) with PhilZ Touch but if it isn't, that means you lost your IMEI. I remember I read about that somewhere, that there is a risk of losing IMEI when you flash a lot of ROMs.
If you have backup from your IMEI, just restore it. If you don't, I don't know what you could do, but I guess you could still do something.
One more thing: Wi-Fi works?
Like I said, I don't understand a lot, so everything I just said may be very stupid. Or not. Sorry for bad english.

My imei and everything is in place, I tried flashing stock rom, custom rom, factory reset phone, tried almost every modem there is and still no luck, but the thing with mine is when I go into the town area I get a few signal bars certain area in town, very weird, what could really be the problem, I know it's not my network or my Sim card so what could it be

Did u ever solve ur problem? Still having this problem

Hey rumbo76 hru, this same problem happened with my brother with note 3, but in here india, he did tha root and falsh tha rom, then he lost root, then he goes bak to stoke firmware so he lost hus signal, and IMEI shows UNKNOWN no network registered, but he search his original firmware n falsh, and he got network n imei number bak, so plzz read n search ur specific device model number n flash, you will be succeed sure.. Plzz update us... Thnks... ?

Try using wifi tweaks at the build.prop , also there are apps like "andromizer" and "pimp-my-rom" that can make it easier.
About the 3G try deleting your APN and re-entering it according to your carrier.
Try using other sim-card (preffered of other carrier) and seeing if the issue still there.
If it won't help it might be a hardware issue so try taking it to a service center.

thx for your rep, my net mode is set as lte/wcdma/gsm... however, when i set it to wcdma only, on low signal areas the signal drops dramatically, because of freq. change, i keep flashing new modems in order to find the suitable one :/

Hi
that is an option is most likely a modem issue, you could also see what modem your country operator uses ( check in sammobile) and flas it to see if you get an impovement

I already had the newest rom/modem installed since it came out, now I am rolling back all of the modems available in order to find the proper one...

I'm totally messed up with Service mode on samsung galaxy duos. Which caused not recognising any SIM. Help me out to reset everything to Service mode default. Thanks in Adv

@Iway76: You get a kudos for searching before posting, even though this isn't the right forum for you. I would recommend attempting to install a stock ROM using Odin, not Kies, and see if that helps. If that doesn't help, you may have to take the device in for service as you may have a hardware issue like mine, where the SIM card tray died while attempting to unlock the S4 - again - and it just was a coincidence that the hardware failed while working on the service menu unlock.

Problem with a gt i9505 GALAXY S4 PLZ HELP...

My s4 is rooted. The problem is that after some flashing of custom roms my 4g/3g is not working properly . In other words, in all roms above jellybean ( kitkat and lollipop) my LTE and 3G is working only for 1-2 minutes and then my signal drops to zero no signal at all. When i switch to GSM signal comes imidiatelly to full! I have searched a lot in this forum , I have tried many times to change modem , CSC using ODIN ofc, but no succeess so far.. I dont know what else to try or to do differently...I also tried to flash the stock modem but still no success... I would like to add that in 90% of roms that i have tried so far my WIFI , and everything else is working normally ... My only issue is what i had mentioned before...PLZ help me.. I DONT KNOW WHERE TO REFER TO IN THIS SITE...

May be you need to set APN (Access Point Names) for your mobile service provider

I think you have a big misconception about what this site it. It's not a helpdesk. It's people helping people and we are not forced to reply.
You have the losing of the signal also on stock Lollipop roms?

Setting APN is not a switch though, you have to put in settings that your 3G/4G service provider uses. Either search for the settings on the Web or ask your 3G/4G service provider for the settings.

I kind of just saw this in the "unread" tab here on xda, so first I would like to apologise for replying without having your device. But, the only thought that comes to mind is a baseband/modem. Not sure if the sgs4 has flashable modems but it would definitely help if you guys did.

I don't have the device too, yet i'm sure its APNs
Contact your network provider and describe your problem.

I also use a rooted galaxy S4 but model GT-i9500 I have the same problem as you,
can not connect to 3G/4G network with kitkat and lollipop based rom.
All I had to do to fix it is to set the correct APN settings for my 3G/4G network
just make sure that the modem you are using is the same one as your new rom is based on,
I have to do this every time I flash a new rom....

well i dont know but it all seems complicated . I ll try guys !!! Another question to those who have galaxy s4! Is it my misconception or all the roms above custom jellybean make the S4 slower?? Lollipop Kitkat are ok But exept of the Google based( pac-man , cyanogen, paranoid etc..) all the touch wiz roms are slower than a custom jellybean ...
