****Let me start by saying that I did do a full EFS backup... but ignored the fact it went to my internal storage, which I wiped and is now lost****
Ok, so decided to upgrade my ROM from S4 Revolution 7.0 to 8.0. Everything went fine, but ended up with no signal (circle sign in the notification bar) and couldn't register on the network. Did some reading, found out I needed to move to the XXEMG4 modem. Flashed it via CWM, signal was back. All was good.
But, I decided I wanted to shift back to stock. I went through the excellent tutorial here, and flashed 4.1.2 specific to my region (Thailand). Unfortunately I ended up with the old "Could not register on the network" issue. Again, did some reading and found out that once you move to the XXEMG4 modem you can't use an earlier version due to updating your EFS partition.
So my solution was to do a quick root, and flash the XXEMG4 modem again. Rebooted, got registered on the network and my data came back online (H+, 850mhz). I thought all was good but after a day of testing I have noticed my data speeds on H+ are ridiculously slow. We are talking 0.16 Mbps.
I can only think this is due to the modem not being optimised for my network.
Does anyone know any other modem I can flash that maybe faster / optimised for my network in Thailand? (True H+). OR should I wait for Samsung to release an official 4.3 and then flash that with its modem?
I think my EFS is fine (other than the upgrade), but have attached screenshots as I do not consider myself an expert when it comes to modems etc.
Thanks for any help.

Trying that now, will use the XXEMB6 modem and see how things pan out.
And you're right, it is a sh**.
Ok, so tried installing Ariza Patch and then flashing a older modem (xxemb6). No joy. It shows the signal bar, but won't register on the network.
I then tried flashing BUUGMJ3 which registered on the network, but same speed issues. Dead slow.
So now back to the MG4 one. I have noticed what maybe a related issue, my data icon is constantly switching between H and H+. It did this before, but now its all the time.
Have you tried 19300UBEMH1 modem this works on new efs i'm using it now also I think rootSU as got some new modems posted in one of his threads

:good: Thanks for the info, I'll take a look at that tomorrow (I'm a little worn out after 2 days of messing with my phone).
I'm also considering flashing the 4.3 official ROM and seeing if that helps any. The Thai version should land any day now.

My czn galaxy s2 is working perfectly has xwlpd 4.03 except he detects sim but shows no service for sim...
plzzz help me...
i will be very thankful to u.........
Hi!
Since you are new here, it might be the best time for you to read the forum rules just to get you informed.. http://forum.xda-developers.com/announcement.php?a=81 check it out!
1. try inserting your sim in another phone, if you find a signal in the other phone, then there might be something wrong with the s2..
if there is still no signal, then it is a network related problem and call your network operator
2. if you find a signal in the other phone and not in your s2, then you must flash a modem..
DEFINITION:
*Modem/Radio/Baseband is all the same thing and can be seen by going to Settings - About Phone - Baseband. It's basically a driver which receives and sends Mobile Network signals as well as handling switching between GPRS, 3G, HSDPA etc....... (but not WiFi connection, that and switchover between Mobile Network and WiFi is handled by the kernel). Reasoning as to why Modem has no influence on WiFi can be found in this post by Entropy - http://<b>http://forum.xda-developer...count=6556</b>
USAGE:
*There is no one "Best" modem for everybody. Unfortunately you actually have to try to find the modem which works perfectly for you on performance, strength and battery drain levels. The good thing is that from my lengthy 8 month experience with Galaxy S2, I'm happy to report that there are a few modems that seem to perform well geographically for most users. These modems are KE7, KH3, KI3, KI4, KL1, LPS, NEKF2, NELP2 & NELP3.
COMPATIBILITY:
*Modems do not need to be matched up with firmware like it's done with ROMs and Kernels. For example, a KI4 modem can be used with a KL1 ROM and the other way round. The only thing you need to pay attention to is what model your SGS2 is. 9100 and 9100 modems are compatible across both models. However, 9100 model and US variants are not cross compatible since the devices are designed to work on different bands.
INSTALLATION:
*I will add a flashing guide to post number 5 soon, hence why it says "Work in progress.....". For the moment I suggest asking Mr. Google to do a search for you. Bottom line is, for CWM packaged modems you need to be rooted and have a working CWM recovery (flash the CWM modem zip within recovery). For .TAR packages, all you need to do is flash it while your device is in Download Mode and connected to ODIN. The .TAR file should be selected in the PHONE field. Don't touch anything else.

I have an S3 i9305 4g lte version, on orange network uk. I rooted the phone using CWM. Then installed the Panorama ROM, using the guide on here. And yes i have used the search function, followed pretty much every guide there is. Still no solution. Im beginning to think my phone will forever be caught up with this problem
on top of there being no service. The phone itself has started to randomly turn off, and also lags!
I regret rooting lol just wasn't meant to be.
Can anyone help me? Literally, I would be so grateful if someone can actually help me fix this problem. I basically just want my network service back, regardless of unrooting or not.
Thanks a million in advance!

Hi,
I recently juz flashed few ROMS such as Pardus,Gorgoid,NeatROM,Omega and etc.,only those available with 4.3
Everything was so great except for one thing...my network speed...it is damn SLOW!
At first i thaught something wrong with the ROM..so i changed...keep on changing from one to another but ended up all with the same problem.
So i thaught,shld be my telco network service interruption but then when i flashed back to my country(Malaysia) official 4.1.2...the speed was normal...
So,can anyone help me to figure out where is the problem exactly?
How to overcome it?
Any helps would be great

Do you have a valid IMEI? From which ROM did you come from?

I don't know what an IMEI is, but I firstly came from a normal rooted 4.1.2 firmware. It was a stock FW. But now, I use a " aokp_i9300_kitkat_nightly_2014-01-14 ". I'm switching around ROMs to experiment, and I seem to love the S5 ROM except that the mobile network won't work.
I've seen this as a solution ""If you don't have reception (no signal), here's a quick explanation: THANKS TO S0ul_
It means you flashed a new modem over the MG4 one. It's not a bug, that's because Samsung has changed the format of the EFS partition with the MG4 baseband and now the older modems (MC2, etc) can't read the IMEI from the EFS, hence the failure to register your phone in your carrier's network.
To fix this issue you need only to install MG4 modem from aroma installer"
But I do not know how to apply it on my phone.
bump.

You had to backup your EFS partition/folder before, try to search in sdcard if there is folder or file like efs_backup, efs.bak, efs.zip, efs.tar.gz etc maybe aroma did it.

Stop to flash any other rom. first try to search for that file or folder because the first rom you installed uses AROMA and MAYBE it did a efs backup, otherwise try to flash a pre MG4 modem to fix signal.

Don't flash or do anything else like restore an efs back until you guve more info.
You have not answered my question above. Is it only mobile internet you have issues with? Can you still use wifi, make calls, receive calls, send and receive texts? If you can do all of that your efs should be fine and it points to apn issues which can get mixed up when flashing roms.
@raksati
You need to read up on efs thread before giving such info, flashing a pre mg4 modem will solve nothing as it can only read efs V1, if he has indeed corrupted the efs then nothing will be able to read it.
What I think you ment was flash mg4 or above which can read V2 but this is only required if using 4.1.2 or an early 4.3 which no one should be using these days.

In some GSM Networks the phones use the IMEI adress to acces data. This could be your problem.

Hi. You could try 2 thinks:
1. This could be a software provlem and flash stock rom or another then try all the modems again and see what happent.
2. This could be a hardware problem and change your phone motherboard !

Mine is 74 usualy and when a i have bad signal it is 98+. Can you check your signal in other parts of the city you live in?
It can be a provider issue .
