Hey guys I'm having a little problem with my GT-i9505. Problem being that I cannot get any reception on my device. It first occurred when I flashed a 4.3 rom over my 4.4.2 rom. I've tried switching to several different roms, both 4.3 and 4.4, yet none can fix the problem. I've tried to flash at least a dozen modem's in a bid to fix it. I searched for the modem suitable to my device and yet they still didn't work. I even tried to just install the official Samsung 4.4.2 rom via Odin, yet I'm still having the same problem. My baseband does change whenever I flash a new modem, but I still cant get a signal. When I try to search for a network in settings it lists the main carriers in the UK, but when I try to select mine (3 UK) it doesn't allow me to register, clicking select automatically yields the same results too. I've been searching for hours today on how to fix this, but just can't seem to find a method that helps. Any suggestions?
Have you tried manually entering the APN settings for 3 UK?

Take your S4 to a repair shop. Use Phil,s recovery when you re-root, install Omega ROM or another Samsung based ROM and, using Philz Touch 6 recovery, make a copy of your EFS file so if / when it happens again you can reinstall Omega or whichever ROM you installed and, using Philz recovery, you can reinstall your EFS file.
To make the backup, reboot recovery - backup and restore - custom backup - x (only in efs backup) - start custom backup - choose where to put the backup.
I use Omega as a reference because I know it will not screw up your EFS file.

Is there a way to fix this without having to spend anything? I literally can't afford to take it to a repair shop at this time
Also, my IMEI still shows as it should (corresponds with the IMEI on the back of my phone)

I had the same problem with my i9500 after flashing a Slim rom Perhaps you can get a copy of an efs file from someone with the same phone and then put it on your phone, or get the information you need from your phone company.

I now have exactly the same problem as you. I tried (once again) to install a new ROM on my i9500 (SOKP this time) and now (for the third time) my phone won't register on the network. I'll take it to China Unicom in the morning and let you know what happened. Unfortunately I don't speak Chinese very well but I will try to watch what the repair guy does. Perhaps it will be of some help.
I took the phone to China Unicom but the tech that repaired it last time wasn't there.
So ur problem is not sorted then?

What u mean by purchase a new baseband bro?
did you try searching for a signal outside?
i'm on three uk network and signal indoors is absolutely atrocious! (especially since they started "upgrading" to 4g networks - i had the exact same problem with t-mobile switched to becoming ee, i don't know why these companies are so intent on breaking networks which worked perfectly before by "upgrading" them).

Check whether EFS folder is backed up by flashed rom in sdcard. If your lucky you can use backup file to get imei number back. Few posts also suggest that flashing back stock rom also get back imei. I am not sure of it. Better back up efs to your pc.

EFS is a folder in phone's file system which saves your phone model, IMEI number and lot more details, Important folder. Flashing ROM the efs folder got corrupted causing the loss of imei number. Try "radicalisto" reply and update the issue.

So a few days ago i downloaded a rom for my Telus SGH-i337m which gave me apps and the features from the S5. I installed it and all that, but then it failed. So i tried to use my back up but it was corrupted as well. So I thought i can go online and find a stock image, i found many, but then I think i installed the image for a GT505 by accident. This gave me my software back but then i could't use my wifi or my data. So i found a proper SGH-i337m rom and installed it, my wifi came back but my data didnt. I thought it was because of the wrong modem, so i installed a few different modems and nothing worked. But today when i downloaded a different modem and installed it using odin mobile pro. It was installing and it rebooted, but then it got stuck there with the ODIN logo. I removed the battery and turned the phone on but not it says "Firmware upgrade encountered an issue..... please connect to kies". I tried connecting to kies but couldn't.
if someone could provide me with fully stock firmware and modem with easy instructions i would appreciate it, I'm so cheesed of my phone not working now
Did you have a custom recovery installed? Have you tried to go into recovery? Vol up home power. Make sure Samsung drivers are installed on your computer. Save a rom on your computer that you know works and place it on the sd card of your phone. Install rom. Try a stock rom version. Maple leaf by ib4stid would be a good one.
I just reread. Sorry I don't think my suggestion will help. Good luck.

what do you mean? you need to create an account to be able to download. hope u got it sorted or by now
If you can give smoe more information about if you have a custom recovery installed (which one), can you connect to PC and move files to the external sd card, which modem you have installed and does the phone boot at all?
The procedure should be, root... download rom, ensuring it is for the i337m and not the i337 (2 different models) install custom recovery (I like TWRP (shouold be version 2.6 or lower.. some suggest 2.5 see mapleleaf rom OP..... others use Philz recovery... I don't have any experience with that).... install rom... let it boot up and run for a few minutes... then if you dont have the proper modem install the NC1 modem found on this forum...(I never flash the nonhalos file) I like to use Odin PC rather than moblie Odin... make sure you take off auto reboot as the flash takes longer than Odin allows before rebooting... You may need to enter your APN settings in settings... wrong APN's will result in no data...
As for roms, I would start with Maple leaf and see what you think... If you need to go back to stock, sam mobile roms are all Bell so you will see some Bell software (not to worry) and you will need to enter your APN's... then you can install a custom rom... again can't stress enough to choose one that is for i337m
The other thing you want to watch is bootloader versions.... once you go up in versions.. you can't go back...
Thanks for the help! I don't know how that I forgot the fact that I have a TelusS4 with a Wind sim in it, and cuz I formatted the phone and crashed the software, the bandwidths went to the stock Telus ones. But then I used a software and now I can use my wind sim on my phone!
Btw what are the best roms out there that look completely stock but provide tons of new features?

Stock roms, I use Mapleleaf, I have also tried Google Play edition by Danvh but went back to maple leaf. I take it you are now back to stock and rooted, before you flash a rom, make sure you do a backup of your current stock rom so you have a easy way to go back. Make sure you back up your imei files also... might come in handy some day... I did both a full backup plus a seperate back up og just the iemi file... like i said before.... if you entend on going backwards from 4.4.3 or 4.4.2 to anything else do not change your bootloader... before you flash a rom make sure it will not change your bootloader... if it is going to i suggest you unzip the rom, remove the bootloader file and rezip then flash... it is up to you though... there is no going backwards on bootloaders......

If is not hardware, chances are that the efs folder is corrupted.
Try a different kernel
Try a different modem
Flash full wipe custom rom again..
Last flash stock rom...
If all fails the problem most like it is in the efs folder, if you have a backup restore it

same issue.
I have the same issue as described by the op.
I flashed back to official 4.4.2 and the problem persist.
IMEI number is correct.
IMEISV is 01
Ive been trying to fix this for over a week to no avail. Losing my mind. Is there anything else you can suggest to fix this issue?
Phone is an i9500.
Was really hoping for some help by now. This will be the second time ive posted to this site in the 2 years ive been here with zero responses.
As a side note. I wanted to add that at the same time i started having the "not registered on network" error my sd card stopped being read by the phone also. I replaced the sim/sd holder in the phone itself hoping this would fix both issues but it has obviously not. Still not reading the sd. Says its blank or unrecognized file system. When i try to format it it doesn nothing. This is the sd I had in the phone before having issues. It worked fine then.
The phone just suddenly stopped working one morning. I used it to send a couple text and make a call, next time i picked it up "not registered" issue began. No changes to the phone in between those times.
I figured I would add this info in hopes of gaining a response.
Thanks.
My brother who lives in dubai used his sim card in this phone but ever since i got the phone in Pakistan ive tried using my sim but i get no service.
My guess is it only works with 4g LTE but i cant try cuz where i live here's only 3g and 2g coverage.
So i started using it as a wifi tablet.
Dialed *#06# and it showed both imei numbers but ever si ce i updated to purenexus 7.1.2 rom it gives me the same service error but dialing *#06# gives nothing but two plain zeroes like in the screenshot. Can anyone please help me resolve this i would greatly appreciate any help regarding this.please help my phone is useless without a sim card.
Screenshots show how it detects the sim card perfectly and gets the number.

Hello, yesterday i bought used samsung galaxy s7 edge dual, sm-g935fd. It was rooted, owner said root was done to flash a rom to let phone see two sims. Went back home, started to install apps, and saw that snapchat doesnt work with rooted phone, so turned superSU, chose full unroot, phone did restart but stuck on bootloop. All I saw, was csc:g935f0xx1bph1 and pda:G935FXXU1BPLB. Could't find matching pda and csc roms, so installed another, for g935f, and everything worked fine, except from network, it only says emergency calls only and no signal, but it finds that my sim is from tele2.
On other thread i saw that i can use home_csc for my csc code, and any other pda, bl, ap, tried that and odin failed to flash it, so now flashed netherlands stock rom that changed my AP:G935FXXU1DQEF CP:G935FXXU1DQD7 CSC:G935FPHN1DQD1 Model: SM-G935F/DS.
Can you guys help me to get my network signal working again? I think that matching software for my phone would fix it, but i cant find which one to flash, or is there anything else that could have caused that?
Thank you for your help.

Sounds like your EFS is corrupted...
*Encrypted File System (EFS) | The EFS refers to a folder called EFS which can store information like meid, imei, serial number, config, diag settings and radio settings, etc in an encrypted format at the file system level stores. So it is very neccessary for us to backup EFS before flashing ROMs.*

same result, my phone sees my sim contacts, it sees which career my sim belongs, but cant connect to it, phone acts like im not using sim, i cant do any call, just tried to do these *#xx#* things without sim in my s6 edge and the result was the same as in s7 edge with sim

i dont think that they can help me. I am not really good in flashing, because english is not my native language so i dont know what kernel means, whats the difference between firmware and software, and even rom, but i think that i have wrong bl/ap/csc/pda or something like that. Found that F in sm g935fd means it is international, looks like i can flash any country unbranded stock rom, but somehow it wont work for me, and i cant believe i did that much damage just by clicking on unroot in superSU app..
