I have recently installed the rom from the link below, during instalation I remember the installer asking if I wanted to install a new modem, to which I clicked yes (i know what a clown), anyway since then I have been unable to connect to my mobile internet service provided by giff -gaff (o2).
http://forum.xda-developers.com/showthread.php?t=2311671
I have tried flashing Omega rom (v51) which I usually never have any issues with, I did notice during installation of the Omega rom that it installed a new Modem, but I am still unable to connect to the internet.
I have looked in my phone settings and ensured the APN for my network is selected.
Do you think I need to install a new modem on its own if so how do I do this can this just be done with recovery like flashing a rom or is it more complicated, and if so can someone explain in layman terms how to install a working modem.
If I can not install a new modem, would I be right in saying I need to go back to stock, if does anyone know a fool proof guide as I have tried to do this in the past and failed.
Thnaks in advance

I'd suggest you follow the guide in general forum, stickies, on how to factory reset and flash the latest stock rom for your country.
If it all works on the stock rom then don't flash anything else until you've read all those other stickies, otherwise you are going to brick your phone.
If it doesn't work on stock then you need a repair centre.
Would that be this thread/ sticky

Thanks, I did see the post and was the first thing I tried, when you go through the aroma installer it gives you two options either install or dont, I have tried both and still no joy.
I would like to try to install a modem can anyone tell me how to do this.

Hi I was just interested in which way is best to root my device and why.
I broke my last galaxy s2 doing it via odin as I was unable to unroot it.
This time I have done it the superoneclick way and unrooted via ginger unroot app.
Yes I'm a noob and someone if any one answer will have a pop about which thread I should've gone to, but looking around for the last hour has shown bugger all.
I could'nt for some reason unroot with odin and am baffled why.
Any help would be appreciated
Regards Shaun
Root using one of the many root kernels.
Unroot by flashing a stock ROM from this thread: http://forum.xda-developers.com/showthread.php?t=1075278
Easiest way just flash CF Root via Odin. Job done simples.
Yes, I'm going to have a "quick pop". Initial search of Q&A forum turned up very similar questions, this is where you should have posted instead of creating a new one?
http://forum.xda-developers.com/search.php?searchid=8243020
Answers are above, including the link with guides.
Hi I did this the first time via odin, but was unable to unroot.
I used an insecure kernal and had the original kernal but when I flashed the original kernal back it was still rooted.
So this may be a silly question but why do I need to flash a rom as some people seem to suggest?
Sorry to sound thick ( I am I guess ) but so much info has really baffled me.
I thought you downloaded an insecure kernal and flashed via odin and that was it, rooted, then if you want to unroot you flash the original kernal, use usb jig and job was done.
Or am I way off lol
Again sorry if I am that bad
Regards Shaun
If you flash back stock firmware, busybox and superuser are removed, so you won't have root access. Also stock kernel as part of the package will instal stock recovery.

The actual rooting process changes (adds) things to the system, that's why you need to flash a "clean" one to unroot.
The unsecure kernels only provide the means to perform the root, they don't do the actual root.
Kernels like CF-Root or mine (see sig) do perform the actual root on boot, but as said above, it involves adding things to the original system.
First and foremost, thank you all for your info it is much appreciated and I mean that.
But I am totally lost and still have a screwed of G2 in the drawer.
I have followed advice to the T and some how I am no better off.
I mean what has firmware and roms got to do with rooting or unrooting.
I just want to get to grips with rooting before flashing firmware or at least someone to say what I did wrong.
On my new G2 I did it via superoneclick is that wrong?

Thats usually in most cases not following the relevant instructions .
This method works but if you cannot understand it then leave your phone unrooted and start reading the Guides and FAQS .

Flash a fresh/clean ROM like suggested in this thread, that should most definitaly fix that phone and get it back to fully working state.
So just before I do this flashing the firmware, just to make sure you understand!
I do the flashing the firmware as if I was flashing the kernal?
Also I'm on 2.3.4 will it stay as that or will I have to use another firmware for that?
Again sorry if I am getting this wrong and thank you for your patience
Get a USB jig.
Flash your stock rom of choice from the intratech thread.
Flash speedmod kernel or whichever you want to gain root.
PS. You shouldn't be flashing anything if you don't know what your doing.....

The intention is to get the phone in a working state, so you can just about flash any official firmware you like. Your Android version will also upgrade if you flash a newer package.
Good reports about XILA2. May have a few Italian apps on it, you may wish to keep them or uninstall later. You may have to flash a seperate CSC later, or just manually enter your APN.
Follow Intratech's instructions and go for it!
It just shows the Samsung Galaxy S II logo with yellow triangle and exclamation then a black screen???? I still can go to Recovery and Downloading Mode.
It is GT-i9100 running 2.3.5 Gingerbread from Saudi Arabia.

Did that. No avail.
One thing that I could add to my statement. This is a brand new device. One day old. I did root it from these instructions
software2tech . com/2012/04/10/galaxy-s2-android-4-0-3-i9100dxlp7/ (remove spaces)
and after that this happened. Whenever I'm charging the phone it just shows a green battery meter with some dots on the bottom. Then if I turn it on again it will go back to a grey battery with a spinning circle and after that the usual green battery meter.
How should we know anything about a method from another site ? Ask on the site you got the method from.
Alternatively...
Look for a kernel that matches (or closest match) your current kernel that you can find in settings/about phone in the CFRoot thread & follow the instructions to root your phone. Read the thread very carefully, particularly the bit that says "Help! Which file do I use ?". I won't be answering any questions about which kernel you should use. Read the thread & you should be able to work that out for yourself.
Edit to add - Make absolutely sure you have an I9100 or an I9100T, check the sticker on the phone chassis under the battery.

It is def. an i9100. I'm gonna try the fix from the Fix an unflashable or softbricked GSII thread. Would you think that would work? I don't want to get rooted now because all of the problems it gave to me.
Silly boy. I used superoneclickroot to root mine, very easy. Or use cf root again very easy, word of advice tho- you wont get much help on here if you got a guide/root/rom from some other website.

have you tried flashing any ROM from download mod through ODIN....
Could I re-root again with Superoneclickroot? This is an unbootable phone by the way. Though yes, I could still go to downloading mode and recovery mode.
I'm new to the Android rooting and crap. I've been used to iOS, Mac and Windows customization so everything is really hard and my mind is basically all nooby on Android.
@zaheedahmed - I'll go to factory Android ROM at this moment of time until I could resort all of the issues I have.
If you don't want to root, then go back to stock. Search this thread, if you can't find the stock rom you need there search this thread. Follow the guide in the 2nd one to flash the firmware. If the download links are dead, make a note of the firmware you want (even better if you know what firmware you have now/the firmware which came with the phone) and search Samfirmware.com for it. Follow whatever instructions they have for flashing firmware downloaded from their site.
That will give a you a 'clean slate'/back on stock.

Hello guys, I am kinda experienced with flashing roms and stuff since I owned galaxy s2 for over a year. However I bought a second hand galaxy S3 one month ago and it has a turkish firmware however when I tried and installed a new rom everything seems to work find except the network service all i see is a circle and has no service and i tried many roms even jelly bean rom (which worked fine with my friend's S3) even i installed the same exact firmware that i had when i got the phone with the same kernel but got nothing :/ then i took it to where i bought it and he told me i can not install any rom on it and just the one i had on it then he took it for like an hour and it was working again... but its really bothering me! what's wrong? i want to install jelly bean or cyanogenmod but afraid to lose the service again i read its something related to radio or stuff? so any help please?? and here is a screenshot of my kernel and rom..

One search before posting and read the faqs and guides before not after flashing .
Two it requires you to restore your backed up EFS as per the faqs and guides .
Not read the faqs and guides and no backed up EFS then you require a service centre .
#But you can try a factory reset and flash stock rom first .

now i am on EMF6 stock rom and i was having the 0000 serial number problem and got it fixed by ariza patch v0.5
i want to flash mj9 rom..i know that there will be a problem with the efs thing
so what steps should i make before flashing the rom?
i have read the efs related threads and still dont know what to do
Yes, there will be a problem with your serial number, you will lose network connection. Patched modem will probably help but you'll have to try before you'll know.
Else stay with your current rom, as everything works.
This information is already available in many, many threads -starting a new one so that you get a personal answer, also dictating to the moderators is pretty arrogant.

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.

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.
