Flash your original modem .
Did you full wipe before reverting to ICS .

Check your APN settings before you go flashing any modems. Google for your provider's defaults if you aren't sure.
Me too with French carrier.
ICS modem are compatible with JB rom? i'm not sure...

No, you will need a matching version.ICS for ICS and JB for JB.

It is really important, that you made a clean install. Wipe everything including system, data, etc.
This was my reason for bad signal etc.
If something is left from old firmwares....you know what I mean
i know, i have wiped everything, but same problem, Maybe LH8 modem is different.
i think i come back on LH1.
Did you make a backup before flashing?
Yes with go backup. Why? I'm in LH1, and i have the same problem. You think it's my backup?
Edit : no, internet work, just my phone change all the time H+->3g->H. But in LH7, the phone take most time to change in H+, now, in LH1, when i'm using internet my phone change immediatly network in H+. It's weird.
I don't understand why my phone doesn't stay in H+ alla time, i have full bar of network.
Sorry i'm french if you don't understand what i'm saying.

So I'm downloading Wanam stock deodexed XXALF6 firmware to be flashed in CWM which says "NO WIPE".
The modem is DXLEA
and it says it's Malaysian.
Here's where my confusion is. I think my modem is LF2 (according to Kies)
Will I need the same modem as I have now for best compat with my network? Can I install the CSC for my network to keep APN stuff and MSS without it altering the stock sammy nature of my ROM?
Also... is everything going to be in Malaysian?

just flash modem only for your country for standard result. for best result, try all modem available for your phone. no need install csc just to get APN stuff. it's automatically generated, same as nexus (do you know that s3 copy nexus features? )

I don`t know about Malaysian language included in the rom, better check on the Wanam thread. As for the modem it can be changed by flashing another modem eather through Odin or cwm. Your apn settings will remain unchanged and are not beeing changed by using another modem. Modems can be flashed here http://forum.xda-developers.com/showthread.php?t=1740061.
Thanks ^
I dunno if I can be bothered messing with the modems, though, I get a decent speed, around 2mbps, which is better than my old Orange phone

Which did you try and which did you settle on?
I depends on country and carrier (network provider) so what I tried and am using is no use to u. Unless your in England and on Vodafone. Just get the speed test app. Flash a modem. Record its speed. Flash another modem etc etc and work out what's best for you.. that's my best advice

Cheers fellas, just about to flash that ROM so I'll start a few more modems downloading now and give it a shot.
Recently I upgraded to cyanogenmod 9 from 7.2 and noticed that the phone was not detecting the GSM phone network. Then using clockworkmod I installed another modem and the phone used to detect the network. But the phone used to lose network on restarting and again I install another modem and it starts working again. My phone had no issues in 7.2 and now I have reverted back to 7.2. Can someone help me on why this is happening. Thanks for your help.

Factory reset after changing Android version is necessary.
On CM7.2, do 3-wipe-combo (/system, /cache, /data)
Flash CM9.1 and reboot.
There is no need to wipe data after flashing.
Upgraded to cyan 9.1 and did a factory reset. Still experiencing the problem. I am trying out the various modems with mixed results.
My doubt is if a particular modem is working, why does the signal drop completely on restart?

Hello,
I own a samsung galaxy s3 gt i9300. I rooted my phone and stuck to stock modem for a while. I then flashed paranoid android 3.15 on it which still used the stock modem. Then i flashed omega rom on it which changed the modem I guess and now I cannot connect to my local number. My IMEI number is there so my EFS is secure ( I have backups of it too). I tried flashing XXELLA modem first since that came stock with the phone when it came. I tried multiple other modems like XXEMB6 and XXEMC2. But it wont connect to my mobile number. I live in Pakistan and bought it factory unlocked from samsung.
Can someone please guide me as to which modem to flash? This is a modem problem right? Because that means I can never flash custom software with different modems. Or is it a CSC problem?
This is the thread i used for flashing/downloading modems! http://forum.xda-developers.com/showthread.php?t=2076857
First attachment is the stock configuration the phone came with
Second is the new ROM i put in which is omega rom.
I even restored my nandroid backup of the stock working official samsung ROM. But still no connectivity. Someone help please!?

Called up the network. Everything is fine on their end. And I was told APN settings is just for Mobile Internet (GPRS/Edge yeah I know Pak doesnt have 3G yet lol). It happened right after flashing the new modem. Any other solutions?

I checked the IMEI. Still there.
Sim works properly on another phone.
CSC settings I tried of many regions (through CSC changer app) from EUR to PAK to even MID (middle east)
As for modem, I flashed stock firmware from sammobile for Pakistan, the latest one, and it still refuses to connect. APN is fine according to network.
P.S. I dont know if this holds importance or not, but I did experience SDS. And my local repair shop (owing to the abysmal samsung warranty policy in pakistan) repaired it. But they did not change the motherboard. They changed the 'chipset' only and upgraded it to 4.1.2 firmware with the sds patch fix. Might be a stupid question, but could it be that the new chip hardware they put in is from a different region, so they had to flash a different regions firmware, and the answer to all my problems could be flashing the one they flashed after i ask them!?
Thank you!
anyone?
Read the rules, do not bump before 24 hours has passed. I will report it next time.

okay! that's good to hear. but i have a doubt, what was the firmware base of the ultima rom you installed? and also what was the firmware you were using before you flashed that? there might be a change in EFS format and that might be the reason.

Well when i started all this 4 months ago i didnt know anyting about anything so i didnt do any type of back up of the original firmware before ultima rom, i dont know what firmware was it but i can imagine wich one was it because was from a company called "Claro" from peru so may be if i get lucky there will be only one firmware from that country and that company. The Ultima rom i flashed that time was the v13, i know the EFS have change and that's proably why all this is happening i cant find a way to restore the EFS to it's original form.. probably if i found a way to do that i would even make the ultima rom work here too
There's no software solution for this unless you have efs backup , visit nearby service center
sent from marijuanated muffin
there must be a way. i mean if i install the ultima rom v13 and use the efs from that back up i made at least i should have the v13 with mobil networkin working right?
Did you try ultima rom with a custom kernal, if not give it a try, just reinstall the rom and the option is there on install.

Ok, few questions:
- check your imei *#06# does it match with your phone's? Check under battery.
If its different you messed up your efs partition indeed.
- that backup you have, was the phone working when you took it? Do you have access to its files? If you never installed any Samsung based rom that changes your efs partition format (newer official ones), id just try to replace the efs contents with the backup ones (assuming its a working backup). As far as I know, apart from the new roms that change efs's format, roms dont touch that partition so it should be fine regardless of where you took that backup.

- No, the IMEI that now is on the phone is: 004999010640000 very diferent from my imei on the back of my phone
- the back up i have is from the efs from the last working ultima rom, that ''working ultima rom'' only had the mobil network working but not the 3g. i tried to instal a stock rom and it didnt work so now i am trying to instal the older version of ultima rom that i had back when i did the back up of those efs, hoping that may be i will get mobil network working again at least.
anyways, i found a tool called SRS server that may help me restore my IMEI in any rom, my question about this is if i restore the IMEI on any rom to my original IMEI the other files from EFS dont affect the phone also? i mean if i only get my IMEI back on the phone no metter the rom it is, it will work?
Don't use the tool. Getting the imei correct is the easy part.
First thing to to imho is to go back to latest ultima. Ensure you choose the custom kernel not stock in options. Ensure you have the mg modem.
Lets to that and take it from there

Also i cannot connect to any wifi network but theyre being found . ive looked everywhere and found no answer. Please help me on how i can fix it.
I'm guessing that you made no efs backup? Do your phone's cellular functions or wi-fi work while running a custom rom? What kind of GS3 do you own (i9300 or i9305?).

You cannot go backwards to 4.1 with out a efs v1 back up. Somewhere in 4.3 samsung updated it to v2.
Without a back up you can only use the latest 4.3 and upwards.
