ROM Signal lost?? - General Questions and Answers

After installing custom roms like Cyanogen or paranoid etc. I lost my IMEI and unable to recover. So I flashed recovery again and back to normal. I did researched and tried a lot of times but still lost the signal. I am using Samsung i9300 (s3).
Like this
BASEBAND VERSION :UNKNOWN
IMEI:UNKNOWN
I also tried to use EFS pro to restore IMEI. However there are no effects.
So how can I solve this issue with custom MOD? Please help.

start by flashing stock ROM to get baseband back

[Q] Flash, Root, and Odd Happenings. Help?

Ok, so I am somewhat new to the whole rooting and flashing of phones. I own the Samsung Galaxy Ace, from Koodo, and last night following a tutorial to install CWM4 and updating it to CWM5, followed by making a Nandroid backup and flashing Ice Cream Sunday Final, I had some issues.
The flashing went without any real problems, except one with installing CWM, but I sorted that out. I booted into the new ROM, and liked it, but after testing it I noticed it wouldn't load anything from my Koodo SIM card, like my contacts, and in the notifications bar where it shows your service carrier, it just showed a number. I was still able to send and receive calls and messages, but it was as if it didn't fully support my SIM. After finding a few things I didn't like with the ROM, I decided to use my Nandroid backup to restore, and after following a tutorial, I "successfully" restored the backup, according to Nandroid... But upon booting the phone, it was stuck on the boot logo.
After about an hour of searching, I was able to find out that CWM5 has issues restoring backups through Nandroid, and that I was screwed out of using my restore. I found the stock Koodo 2.3.4 ROM, and flashed it with Odin, and had to do a Recovery System Wipe to get out of a bootloop. I thought I was back to square one, and began installing my apps again and such with no issues.
---------EDIT---------
So, after hours of fooling around I replaced my save file with Root Explorer, like I was before, but then gave Terminal Emulator SU Permissions and used it to give the save file the right APP ID and Permissions, and it's working without freeze-ups now. I also used SQLite DB Editor to edit a fresh save on Where's My Water to reset my progress back to where I was before the update broke my save.
I am still wondering why my SIM Card didn't work properly in that ROM, and if there is a way I could make it work.
Is your model number GT-S5830D with baseband S5830DTLKI4? This is my model of the SGA and I've been reluctant to try flashing any ROMs because I can't find any success stories for this exact model. I'm also with Koodo and have concerns about how the SIM card will handle the custom ROMs too. If you do have this model, what has your experience been since your original post?
Winner Winner Chicken Dinner!

My model is GT-S5830D and I am on that baseband and have tried a few ROMs, all of which work. I would say try a ROM as the you should be fine, and you can always do a CWM Backup.
The SIM issues I was having has been resolved, as it is simply caused by being in Canada, and my carrier not being in the phones list, so it still displays a number, but all of my features (Calling, SMS, MMS, Data, etc) work fine.

Problem when flashing CM ROM

I'm not sure if this has been covered in another thread, but I was looking around a bit and found nothing and sorry if this isn't the correct place. I wasn't sure.
I have an LG P509(TmoUSA). Yesterday I rooted it for the first time and installed CM10 on it via ROM manager. After it successfully installed, I noticed I didn't have any signal and that my imei was missing. It said "Unknown" . On my dialer I pressed *#06# and a little box popped up with nothing in it. I switched back to stock rom using LG tools and both my imei and signal had been restored. I attempted it again but this time, I tried installed CM 7 via the ROM manager along with Google apps. The same happened. I again, restored back to stock. I attempted it a THIRD time, but, this time I did it via clockwork. I cleared cache and data and installed from zip. I installed CM 7 and CM 10 though this method. Both times my imei was gone and my signal was as well. Right now I'm sitting with stock rom and rooted.
Does anyone know what's going on? Can I not install custom roms with my phone without loosing my imei?
I think you did not upgrade your baseband, thats the only reason you are not getting signal. I cant tell about p509 but i had the same problem, but my phone is p500. You have to flash v20 baseband for new roms i.e higher then gingerbread search the forum i have a link but its for p500. Not sure if both p500 and p509 baseband are same anyway here is link for p500 baseband, just ask if both p500 and p509 baeseband are same if they are same you are good to go.

I had the same issue but with cm 9 and upgrading to the new baseband fixxed it for me
Thanks for the replies guys. I was in the process of upgrading the baseband, but I fell asleeping during the back up. I'm doing it now as we speak though. :good: I will post results.
It did work! Upgrading the baseband worked! Thanks for helping me out My IMEI and service as came back.
..and by the way, I think P500 and P509 are the same.

Custom ROM Flashing Problems

Good day to all, ya'll have changed things a bit it appears since my last visit. Okay I don't know what is going on as I have flashed hundreds of ROM's without issue and this morning Im seeming to have all kinds of issues. Sprint Galaxy S4 rooted and Flashed for Straight talk network. I am having some kinds of problems and am not able to flash any custom ROM's. Ive tried flashing GPE 4.4.4 and Super S4 ROM and Im getting a Footers Wrong error, error #7 and Signature not verified error and then it will reboot back to the stock firmware. So being my bright self that I am I toggled the signature deal in Clockworkmod and flashed it again and the phone rebooted and started up in GPE, but I could not get a data signal nor would it allow me to even turn on the wif-fi. and now Ive got it bricked and hooked up to odin. Any suggestions, comments, beatings or there of the likes. lol thanks guys yall are great.
Custom ROM Issues
Okay good day once again....Okay the phone has booted up completely and with GPE 4.4.4 or what I assume is GPE. I have no service to the device what so ever, but it does saying preparing network in the task bar and has been saying that for 20 minutes now, I still can not turn on Wifi. When I go to about device it says the following Software Version - Unknown Hardware Version - nothing Android Version 4.4.2 Baseband Version- unknown Kernal Version 3.4.0-216929 [email protected]#1 Wed Jul 9 09:03:50 2014 Build Number - SuperS4-1.5(which means it isn't GPE it is Super S4 ROM, which is cool especially since one of your guys I think built it) and everything else their looks normal to me. So any feed back on this post please. I have to be at work in a few hours and can not do without a phone ....
Hello...! I have some questions to you.... Do you try to flash a custom rom from recovery right....?
And it says "status 7 error"?
I think the reason for this is that you are trying to flash a rom that does not match with your phone or it's not singed...! For example you are trying to flash a rom for Samsung Galaxy S 4 GT-I9500...

[Q] No Signal - Modem Broken?

Problem Solved - I restored the CM12 backup and now I have signal. Do you folks think I will continue to have problems if I attempt to go back to KK again?
After trying the CM12 Nightlies, I decided i wasn't a fan and decided to try some KitKat AOSP Roms before going back to CM11. My first mistake was installing the AOKP Rom which wasn't officially supported for the Sprint version. During set up I realized that there was no cell data and tried to unroot. My second mistake was when I got cell signal back; I decided to test if the initial loss of signal was just a fluke. Re rooted and reflased the same AOKP rom. Once again i lost cell signal. However, when I unrooted to stock this time there was no cell signal on the stock rom. I have no idea how to fix it. I've tried to flash the .pit i saw in another post and tried to use the "Phone EFS Clear" in Odin to no avail. At this point I'm rooted with a the Stock ROM and no cell signal. I realize I got myself into this mess by being dumb but I could really use the help in fixing the issue.
Info - Rooted with TWRP Recovery running Out of Box Stock Rom.
APN fix!
This will fix signal issues!
Thanks, if I go back to a KK ROM and have the same issue I'll have to try it out.

EFS FOLDER needed? maybe...

I rooted my phone, everything was fine running SpaceX Kernel until i started getting reboots. i flashed arters kernel and when my phone restarted from odin i got a message saying : This phone has been flashed with unauthorized software and is locked. the phone won't connect to the network. if i flash the stock firmware with stock kernel it won't boot for some reason. It only boots up with a rooted kernel but my baseband says unknown and my imei is null. if i flash darthstalker ROM i get the baseband back but imei is still null, i tried changing the imei and masking it with apps but no luck. people keep saying that my efs folder got corrupted... so i was gonna try copy somebody's folder to see if my phone connects to the network. that's where I'm at, this sucks and I'm desperate for help. by the way, right now I'm running stock COI5
Anything will be appreciated.
