[Q] Mobile Network not available after Flashing to custom ROM - Galaxy S II Q&A, Help & Troubleshooting

Hi guys,
This is my first time posting a thread in here. I need your help.
My phone is Samsung Galaxy S2 i9100.
Baseband version: I9100XXKI3
(screenshots attached for more info)
I rooted my phone By using Odin3-v1.85. and flashed the recovery to cwm 5.x (i can't remember version) and tried to install custom ROM OMNI
(omni-5.0.2).
I accidently downloaded and installed OMNI for i9100G version. But my phone is i1900 version.
(I downloaded this omni-5.0.2-20141222-i9100g-HOMEMADE.zip ). i forgot to backup previous ROM .
Then i was unable to Turn ON my phone because every time i turn it on, it come back to recovery it self (it's a bootloop i think).:crying::crying:
then i flashed the recovery to CWM-KitKatCompatible-i9100 (version 6.0.2.7) and installed custom ROMs and tried (PACMAN,CM,AICP).
It works fine. everything is just perfect. But i can't make calls or receive.
It says "Mobile Network not available". when i call my phone from another phone i hear ringing it. But nothing shows in my phone. after few seconds i got a Missed call Alert. But this happens only sometimes. All the other times. i cannot call it from another phone.
I tried reset and flash modem using CWM as well as from odin. but no luck.
Please Friends Help me. I don't know whether i put this thread to right section or not. sorry about that.
I did all of these things by surfing XDA forum (as a Guest). And i'm happy about what you guys are doing. Keep it up.:good::good:
(sorry for bad english)

Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck

You might need to reflash stock rom, then try flash custom rom again.

Thanks it worked. :good::good::good::good:
I reflashed to stock rom and it's working fine.
But i tried to install custom Rom again but no luck there. I was again stuck with Mobile network problem.
May be the problem with kernal.
Any suggestions???

You will have to flash stock 4.1.2 rom or try a 4.1.2 custom rom. The problem may be caused by the drivers in the built in kernels but I'm not completely sure.

No mobile network on custom roms
I have already flashed the 4.1.2 jellybean rom but 4.1.2 rom also havr bugs. Lock screen doesn't work, I had tried hard resetting but it doesn't solve the problem. I Want use 5.0.2 hazy , cynogenmod, pacman , dirty unicorn, etc and other many custom roms but I'm facing same problem no mobile network, other than that everything work fine....

You mean stock 4.1.2 rom? That's very weird for a 4.1.2 stock rom. Maybe an android 4.2 or 4.3 rom?

You are saying that I should try 4.2 or 4.3 custom rom??

use another baseband version. I use XXMS4 and I recomend it.

Yep.

I am having same problem with the network connectivity. It happens with all custom ROMs that aren't stock based. I am stuck with Chameleon ROM which is a hybrid and has a stock samsung base. It is a great ROM but is outdated. I would like to upgrade. Any solution to this problem is welcomed. = D

Okay I think I got a solution here. The procedure is:
1) Make sure you are on a stock based ROM or other ROM where your network is working.
2) Backup EFS.
3) Flash custom ROM of your choice.
4) Restore EFS if there is no network.
Done.
To restore efs, you can use any app tailored to do so but for me it didn't work. I followed this thread:
http://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021
Follow the steps carefully and you will have network in any ROM you like. Hit thanks if helped.
PS: Sorry for double post
EDIT 2: Even though my network is back, which confirms that the problem was with the missing IMEI. I found out that the IMEI I got now is a fake one. Got to get the real one back now..

i did flash android 10 in my moto one power
after that i went back to stock rom but noe netwrok is not showing up

Few Questions guys

Ok so i am noob with Samsung and dealing with flashing and all these stuff, i just switched from iPhone to Galaxy S3 GT-I9300, i have read so many posts and watched so many videos, all what i want is some clarification
1* I have managed to download CM 9.0.0 for my phone and installed it through ROM Manager , i have noticed that my Data service is not working, am living in Kuwait "Middle East" the wifi is working fine no issues and i enabled the Data Service through the settings, how can i fix the issues with the data plan although it is working fine after i restored to my stock ROM
2*Can u tell me what the use of the Odin except rooting and installing a stock Firmware ?
3* correct me if i am wrong but the ROM will only do some sort of interface for the phone , as we say in IT "GUI" of course not to forget to mention the speed and tweaks for hardware of the device it self, i mean it is not a complete OS "Firmware" mostly GUI with Tweaks.
4*While doing the installation of the ROM and remove it and getting back to my stock ROM , nothing from my data has been changed, does that means every time i install any ROM and get back to the old one my data will not be effected on the stock ROM?
5* what would happen if i tried to install a ROM not compatible with the firmware i have ? and how would i fix that ?
6*How can i tell if the ROM is compatible with the firmware i have? , for example in my case i downloaded CM 9.0.0 for my S3 which has 4.0.4 firmware
7* I have understand that the ROM must be compatible with my phone version , what i mean with version like International version or US carriers versions, am i Right?
Am sorry asking too many questions,I tried my best to make the questions with yes or no answer, and incase you would like to write more please do
answering me those questions will help me alot, i have been reading so many posts and it is making me go insane
Thanks so much in advance :angel:

1. try reboot
2 thats about all its for
3............
4 all your data will be there unles you do a full wipe in recovery which is recomended before installing any ROM.
5 A ROM isnt specific to your firmware.If you have an international version which is GT I9300 Or GT I9300T any ROM from the I9300 threads will work. Dont flash anything made for the non international versions

You do a full wipe. A full wipe is always recommended to prevent some weird bugs.

[Q] Wi-fi Toggle Switch is disabled :(

Hello Team,
I have been a silent follower of this website and have rooted my SGSII 6 months ago. Everything was working absolutely fine with no problems.
Very recently I upgraded my build to 4.2.2 JDQ39 with Kernel Version: 3.0.64-CM. My wireless is not working at all. I am not even able to turn on the wifi option.
I tried installing the below ROMs to check the functionality:
ThinkingBridge
Paranoid
Resurrection.
None of the above worked.
I'd request anyone in this thread to give me a workaround or a solution to fix this thing.
Thank you
Harry

Anyone in this forum has experienced this issue before me? Please advice.
Do a clean (format everything in CWM first, then use Odin) install of stock & see if the problem persists. Tho you've tried these other roms, you might have left something funky behind from one of them (just doing a wipe may not get rid of this) that has persisted.
If you have no problems with stock, try another install of the custom rom of your choice & see how you go.
Or maybe even try a completely different kernel before you do the stock thing. Try Siyah/Dorimanx maybe ?

I flashed Official Samsung Firmware 4.1.2 on my GS2 using Odin but still the problem persists.

[Q] Cant install any ROM on my Phone or even perform a Nandroid Backup

Ive tried installing the 4.4.2 ROM Achidroid N7000 on my phone using TWRP but it skipped the MD5 check and said "Installation failed/aborted....". I then tried an AOSP 4.4.2 ROM but it said the same error message. After that, I gave up and tried to use the phone. When it booted up, it froze on the Samsung logo and wouldnt boot up completely. Ive tried doing a FDR through the custom recoveries but still the same thing happens. I really dont know what to do. I have an i9300 under 4.3.
Any help would be appreciated. Thank you.
Follow the guide in general forum on how to flash a stock firmware, download the latest one for your country from sammobile.com.

I dun think archi developed any rom for the N7000. At least I didn't see any when googling. But if you flashed a N7000 rom on ur phone, even if u finally unbrick it, I bet there will be some hardware issues.

Sent from my GT-i9300
The first page alr said tat the rom is VERY buggy and is in the experimental state. Many things are not working in tat rom. So I have no idea why some one would wan it as their daily driver rom.
Issue Solved
Thank you guys. I was able to flash the ROM properly using PHILZ recovery.

Please someone help =(

I flashed this stock rom here http://forum.xda-developers.com/showthread.php?p=53767196 for my GT-i9200 Mega
coming from silentnight's flashable stock rom & another time from C-ROM 4.4.3,
each time i flash the stock rom (http://forum.xda-developers.com/showthread.php?p=53767196) it completes, reboots just fine, and when it starts up my screen doesnt respond anymore ive tried factory resets and full wipes & reflashed multiple times, idk what to do to make it work.
i can still go back to custom roms and my screen works fine on those. ive even tried going to 4.2.2 official stock but that doesnt work either.
someone please help =(
If you have issues with particulary ROM then ask questions on this ROM's thread.Besides - how can you say so this ROM is stock? It isn't and ask developer for help.

i have asked multiple times and im getting no response which is why i took my question here. if u werent gonna help me figure out something u didnt have to reply. and i can say its a stock rom because thats what it is. Stock Russian 4.4.2 kitkat Update for the GT-I9200. the only thing is this developer removed knox & the recovery. ive tried both versions of the rom and ended in the same result.
I would say, to re download your original stock rom, and flash again. Maybe there was a problem with your first download. Or try to find the same ROM from a different source. Then download that one. There may have been something wrong with your original stocker..... Or, try a different version of Odin
Good luck

Never flash RIL on custom roms, you will break network.
Have you tried flashing an original samsung rom to see if network works? maybe your board is broken..

Are you sure you are installing the correct version? Have you tried reinstalling the custom rom(s)? I'm pretty sure that the custom roms use the same modems from the stock rom (doesn't install a new one). Is the network settings ok? Is there any signal strength? Please let us know your answers.

Emergency calls only? This seems really strange. Assuming that your sim is still activated, you shouldn't really be experiencing this problem. If you changed the modem to a different one from the original, I would highly advise you to flash back the original modem (since you have changed the modem).
That just dont makes sense, the only explanation to this would be a rom with a broken ril

Honestly I don't know. I never saw such a problem before, I don't know what you are doing wrong because all the kitkat roms for i9100 have a working network for a year I think. Make sure you are following the installation instructions correctly :good:

Well the stock rom you can get from sammobile and flash with odin, talking about kitkat I'm personally using the CyanogenMod 11 M12, network works flawlessly, but I also recommend @Markox89 linaro/sabermod builds because they rock (and have working network haha)
