This does not belong in development thread. Now, if you come up with a FIX, then THAT would belong here. Come on, guys...keep our dev section clean so that we can get work done. Questions belong in Q&A or in the individual thread that you are running the rom of.
For you n00bs
I'm not sure why you new people don't read the rules and guidelines.
What part of the word "development" do you not understand?
If you have a problem with a posted ROM, then post in the Rom Thread, or the thread that concerns your issue..
If you have new Development..... let me say that again......DEVELOPMENT, then post in the Development Forum.
If it's a question about a problem you have.... Let's see....... Ahhhh... Hmmmmm......Q & A Forum????
Any more posts that get posted in the Dev Forum, that are not Development, will be subject to deletion.

Net Problem.
Well in beginning i also had exactly the same problem. my internet wasn't working.
first of all add the correct APN for Airtel.
APN - airtelgprs.com
restart the phone and it should work.
you should have min bal of Rs 2 or more for net to work on your phone.
atlast It worked with a different trick.
just install tweakker app from google play, choose the county as india, service provider as airtel, airtel as the settings. voila, it works.
test it an let me know.

Hi
i have installed the pandorium Rom and i am impressed with this, but i cannot access internet with it, only when i connect wireless i can connect to internet.
i have put it onto auto 2g,3g,and 4g and connected to orange t-mobile network and still cannot access internet. my iemi number is still intact as i thought it may be something to do with that.
any help would be great thanks

Did you flash a modem did you flash correct CSC have you entered your networks APN settings .
If yes then wipe phone flash stock rom and test .
Never heard of that rom pandorium so first go to where you got the rom and read the instructions and the thread.

****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.

Hi,
So I downloaded this " http://forum.xda-developers.com/galaxy-s3/development/rom-revolutionary-s5-v3-buy-s5-t2602543 " ROM and everything seems well until I noticed that there is no signal. SIM Card is not being read by the ROM. I am new to the modding scene and I'd like a clear explanation on how I could fix this problem.
I have a International GT-I9300.
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.

Hi. You must flash a custom recovery like TWRP or CWM to flash modem software.

I flashed some modems, the signal seems to be fine, but i cannot connect to internet using mobile data. The APN seems fine, is it related to the fact that i my imei is unknown ?

In some GSM Networks the phones use the IMEI adress to acces data. This could be your problem.
Yup the imei was missing. Now everything works fine.

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 !
I dont think it's a hardware problem, the phone is brand new, i have it for like a week.

Can you go to Settings>About phone >Status >Sim status and see if your Signal strenght fluctuates.
-70 dBm Minimum signal strength for reliable packet delivery. Email, web
-80 dBm Minimum signal strength for basic connectivity. Packet delivery may be unreliable. N/A
-90 dBm Approaching or drowning in the noise floor. Any functionality is highly unlikely.
It says -94 to -100. I dont know what the hell that means

"A signal of -60dBm is nearly perfect, and -112dBm is call-dropping bad. If you're above about -87 dBm, Android will report a full 4 bars of signal. "
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 .
I live in a big city (Cracov), provider isn't the issue. I had many phones with the same provider and no problems at all.

Did you try to flash with TWRP modem_P780_v52.zip ?
I read on some Russian forums that it can work. (but remember allways backup)
I did I'm currently using it. but still the same result.
