Hey Guys
New to the forum and having just installed the Energy Team HD 2.0 ROM I am finding a little issue. It seems that the ROM I installed does not contain the correct Modem Info for my version, as I am unable to access my service providers network (ie GSM).
Thank you for any help you might be able to give
If you need further information let me know.
Cheers,
Nicolas

Sorry about that thanks for your reply I will check it out
Can not find anything on the issue that concerns me. I am not having an FM radio problem so it's not that
Sorry if I am a little slow but your help would be greatly appreciated.
I simply have no service after flashing the Energy HD 2.0 ROM on my I9300
Thanks a million,
Nicolas
There can be many reasons for no network, wrong modem is unlikely as most (not all custom roms leave your existing modem). Are your imei and serial numbers intact, APN and network set? Has your handset been tampered with previously, e.g patched for efs problems or lock patched?
Try reading the efs 'know this stuff' for more clues.

[SIZE=+2]Samsung Galaxy S III - International GT-I9300[/size]
[SIZE=+1]This a short list of frequently asked questions with answers related to the Samsung Galaxy S III. It should serve as a starting point for gathering knowledge and finding solutions to many common problems. Please only post in this thread with feedback on how to improve this document and refrain from posting "Thank you" type responses. If you have additional questions or require more help, try to find an existing thread or create your own. Do not use this as a general help thread.[/size]
[SIZE=+1]Q1: How do I root my Samsung Galaxy S3 i9300?[/size]
There are several methods to achieve this:
CF-AutoRoot by Chainfire
CF-Root by Chainfire
A custom kernel like Siyah, Speedmod and others which can be flashed with Odin or Heimdall
Use the toolkit by mskip
[SIZE=+1]Q2: What can I do to conserve/improve battery life?[/size]
Official Samsung Touchwiz ROMs enable Smart Screen by default. You can tell it's enabled if you see an eye icon in the top right corner of your phones home screen. Smart Screen attempts to sense when you are looking at the screen to turn it on and to rotate the screen when you change your viewing angle but it is also notorious for draining the battery.
To turn it off go to Settings -> My Device -> Smart Screen then disable 'Smart Stay' and 'Smart rotation'.
To conserve your battery under official firmwares it is also recommended to enable power saving mode and, for all firmwares, you should turn off the WiFi, Bluetooth and your mobile data connections whenever you are not using them to minimize battery drain.
[SIZE=+1]Q3: How do I flash (install) ROMs?[/size]
ROMs that come packaged as a .zip file are usually installed using a custom recovery tool such as TWRP or ClockworkMod. Unlike previous Samsung Galaxy S devices the recovery for the Samsung Galaxy S3 i9300 is NOT part of the kernel. Instead, the SGSIII has a separate recovery partition. Custom recovery partitions can be installed using Odin if you are running Windows or Heimdall, which is available for Linux/UNIX and Mac OSX as well as Windows.
Some ROMs come packaged as a .tar.md5 file. These can only be directly flashed using Odin. Heimdall users are required to extract the individual tar files from within the .tar.md5 file and then flash them to the correct partitions using an appropriate .pit (partition map) file. Heimdall can be used to generate .pit files by extracting the existing partition map from your phone. Note that .tar.md5 files are actually just regular tar files with an added .md5 extension.
[SIZE=+1]Q4: How can I return to the stock ROM?[/size]
There is sometimes the need to revert to the stock ROM, for example when you need to return your device if its still under warranty. doovd made this great guide to the process.
[SIZE=+1]Q5: What is Odin?[/size]
Odin is a leaked tool from Samsung. It is used to flash firmwares (aka ROMs) to phones. There are many how-to's covering the use of Odin, such as this. Others can be found on the XDA WIKI.
[SIZE=+1]Q6: How do I unlock my bootloader?[/size]
There is no need to unlock the bootloader as it is already unlocked! This is the case for most Samsung devices.
[SIZE=+1]Q7: I have heard about EFS. Why is this so important?[/size]
/EFS is a partition on your phone where your IMEI code is stored. Without it your phone is an expensive PDA as you will not be able to make calls. Make sure to have a backup of this partition on a separate device before you attempt to flash new ROMs. TWRP and Philz recovery let you backup the EFS partition.
The format of the EFS partition changed with the release of the MG4 modem firmware so this can cause issues if your modem version and EFS don't match. Here is an explanation of the Samsung firmware naming convention.
[SIZE=+1]Q8: After flashing a ROM I cannot make calls. I now get a 'Not registered on network' error on my lock screen and if I look under Settings -> About Phone -> Status my IMEI begins with 0049 and my serial number has changed to a string of zeros. How can I fix this?[/size]
There are many threads on this forum suggesting this problem is caused by an EFS/modem mismatch or a corrupt EFS partition. This is a potential cause but its more likely you have flashed a ROM with the incorrect CSC (Customer Sales Code) for your phone network. For example, you can experience this error if you've flashed a BTU ROM when your network requires a H3G (Three) CSC. It can also be caused by flashing a ROM using the PDA instead of the CSC option under Odin. You can check your current CSC by dialling *#1234# or connecting your phone to Kies.
If you flashed with Odin and you're sure you flashed a ROM with the correct CSC, the first thing to try is flashing the same ROM using Odin's CSC mode instead of PDA mode. If your phone is rooted you can try changing the CSC mode using a CSC changer app but be warned that doing so will perform a factory reset - wiping all your settings, apps, messages and locally stored contacts etc. If none of those methods restore your correct IMEI, serial and network connectivity then a number of S3 users have reported success by flashing A.S._id's rescue firmware.
[SIZE=+1]Q9: I'm sure I've correctly flashed an SGSIII ROM with the right CSC for my network but why can I still not make calls?[/size]
If your phone was running an Android version less than v4.3 before you flashed a new ROM then you may need to install a patched modem and, if you upgraded to a newer stock ROM, a patched kernel too such as the zuluman modem FW/kernel. You will usually not need to install a patched kernel if you install CyanogenMod or a CM-based ROM. A number of kernels and modem firmwares patched for Android 4.3+ are available here.
[SIZE=+1]Q10: What is the best ROM for the SGSIII?[/size]
Galaxy ROMs come in two flavours. CyanogenMod-based ROMs and TouchWiz-based ROMs. CyanogenMod is completely open source and forms the basis of several derivatives such as AOKP, ParanoidAndroid and many more. These ROMs lack a number of features exclusive to Samsung's TouchWiz like Svoice, Smart Stay, S-Beam and so on. On the other hand, they generally perform better thanks to consuming less resources.
There is no such thing as 'the best rom', it is a subjective matter. Please read this sticky thread in the General section.
[SIZE=+1]Q11: Where can I download the official firmware files from?[/size]
Official firmware files are available here.
[SIZE=+1]Q12: How do I enable Debug mode?[/size]
Since Android 4.2 debug (developer) mode has been hidden by default. Debug mode can be enabled by tapping 7 times on Build number under Settings -> About Phone.
[SIZE=+1]Q13: How do I enter Download Mode and Recovery mode?[/size]
Make sure your phone is unplugged and powered off, then:
Download Mode: Hold Volume down, home, and power until you see the green dude.
Recovery: Hold Volume up, home, and power for about 5 seconds then release all buttons. This might take a couple of tries.
[SIZE=+1]Q14: What is the 'Flash Counter'?[/size]
Your phone's flash counter is triggered and incremented after installing a custom firmware. This is Samsung's way of knowing that you have modded your device. Thanks to the awesome people at XDA, this counter can be reset. Refer to this thread.
[SIZE=+1]Q15: What is ADB and how do I use it?[/size]
[GUIDE] ADB Workshop and Guide for everyone
[SIZE=+1]Q16: I've been asked to provide a logcat. How do I do that?[/size]
How to read a logcat/ Troubleshoot your own issues!
[SIZE=+1]Q17: TitaniumBackup can't find my backups anymore![/size]
This usually occurs after upgrading to Android 4.2 when users forget to also update the recovery partition. Older recoveries can't handle the multiuser support on the sdcards so your data got repeatedly shifted to a folder named 0, resulting in /sdcard/0/0/0... etc. That is where your backups have gone! You simply have to update TitaniumBackup's settings to point to the correct location and your backups will re-appear.
[SIZE=+1]Q18: I have searched everywhere and still can't find an answer to my question![/size]
Have you really searched everywhere? Google? Have you tried asking in the XDA thread relating to your problem? Have you read the stickies and FAQs? If you have honestly spent more than 5-10 minutes searching for an answer, post a new thread in the Q&A section.

My point is that there are already FAQS and Guides stickied that are unread .All bar question 12 have been posted for a long long time in the stickies .
But i will be honest i have no idea at all how mods can prevent this forum from degenerating even further .

It's been a long time since I registered, but is there some kind of big splash screen that pops up saying read the FAQ/stickies? If not, there should be!
And it should be like one of those annoying t&c's things on windows apps that won't let you past until you have scrolled down.
In fact, you should have to read instructions, saying things like search/faq/stickies etc, then you have to answer 5 questions correctly before you can register!

If you have read Q12, you would have gone to the Note2 section instead of the i9300 one. And I have no idead what you are asking, let alone the answer.
i think you should change the answer to Q7
We have a sticky stating not to post best rom threads - that should be be included here

Hi everyone,
I hope someone can assist me.
I rooted my i9300 device using Samsung Galaxy S3 ToolKit.
After installing Omega ROM 46.1
What i discovered after installing omega rom is that my IMEI number had changed to 004999010640000 and am no longer registered on my network.
I then went to rom manager as i had a backup of my sock rom i restored it but still no network says not registered to network.
i went to a couple of forums n dowloaded offical stock rom from this link (http://forum.xda-developers.com/showthread.php?t=2005286) still no network no back up nothing and the emie is still changed 004999010640000.
current version on mmy ph is
GT I9300
model 4.1.2
basebande version : I9300xxemb6
kernel version : 3.0.31 -1071725
build number : jzo54k.i9300xxemc3
after installing stock rom from this link (http://forum.xda-developers.com/showthread.php?t=2005286)
So basically:
I get the wrong IMEI number when running stock android from Samsung.
and nothing seems to work as not network
Can someone assist me with this? as i am new to changing roms .
You're going to have to search, as discussion of methods to change a device's IMEI is illegal in many places and cannot be discussed on XDA.
Sorry that it's not much help, but the answers are out there if you use Google properly.

Go to Faqs and Guides and read and post in the EFS/ IMEI thread we do not need yet another thread.
As it looks like you failed to backup your EFS as per the instructions its best to take it to a service centre for repair .
Please read the stickies then if you have any questions post in the sticky thread which is actively maintained. Also its IMEI not EMIE
I there all, my imei changed for another one during the upgrade proccess from 4.1.2 to 4.3.

Hi!
I have installed 3rd custom rom that is based on galaxy s5 user interface and thus is the third time I am facing the same problem. Everything runs fine but this doesn't detect my sim card. First I flashed flashingdroid faced the same problem then i flashed efextreme lite v5.0, in this at first the camera wasn't working but solution for this problem was mentioned in the original thread itself. So I flashed the given kernel in the thread and the camera was fixed but again I lost my signals and it said that insert a sim card.
Now I flashed hypermax v8 and again the problem is same, "Insert sim card".
What can i do to fix this??
Please help!!!

For IMEI it says "unknown".

Thanks for your suggestion.
As you told me I did read the latest threads posted here but unfortunately I didn't find anything helpful. As it is I am not concerned with the original imei as far as my phone is working. Also it was working with efextreme v5.0 as mentioned above but after flashing the kernel given for fixing camera i lost the network. Earlier i was using cyanogemod 12 but due to lag and FC'S I had to change the rom. But it was working fine if you ignore the FC and lag however I don't have any idea about what my imei no. Was.
If you find calling and receiving calls belong to a working phone, you've to follow boomboomer's advices for restoring efs-data. Don't understand, why you don't find it, but there is no better.

Could you please share the link.
ONE link is useless. Go one level higher to Q&A and enter 'restore efs' or 'restore IMEI' in 'Search this forum'. Then pick at first the short threads, which are answered by boomboomer. So you'll get an overview and solutions.
(There are also long threads with witchy procedures and only little chance of success. Not very recommendable.)
