Hello.
I had problems with my EFS folder and IMEI.
Now i got it all back and running the Official Android 4.3 Firmware I9300XXUGMK6-DBT
But now i want to go back to custom roms ( Paranoidandroid ).
With the update to EMG4 Android changed the EFS folder.
That was the problem why i lost my IMEI.
What can i do, to get custom roms back !?
Everytime i flash ParanoidAndroid i dont get MobileNetworks.
nobody can help?

In my experience, if you are back and running then search for efs backup/restore programs and backup your efs with as many of them as you can. Save them on your computer as well! Since you are on 4.3 and on the MG4 modem or newer, you are free to flash any custom rom you want, just dont flash a 4.1.2 custom rom or even a 4.2.2 as they will cause problems with your imei. Flash only 4.3 or higher

Hi there,
I have the galaxy s2 from about a year ago, bought it form Dubai. Anyways till now I still didn't get the jelly beans update 4.1.2 and I'm stuck with the 4.0.3. I'm starting to face some problems with my device and I think this is because bugs in the 4.0.3, the device over heats while charging or when I have my wifi or 3G on. I downloaded the "AOKP MR1 Milestone 1 ROM for Galaxy S2 GT-i9100 (Exynos)" along with "Gapps" but didn't install them yet:
The only problem is that in order to install the new rom I have to flash my device and root it and I'm not really happy with that. Is there a safe way to get the jelly beans update 4.1.2 without rooting my device. I tried the over the air update but it said no updates found, I also tried kies and still no luck. What can I do to get the new update without having to erase everything on my device.
Also can I take a backup copy of my ROM in case I format "flash" my device for any reason. I want to take a complete backup of everything on my phone including the unrooted original firmware 4.0.3 that it came with so that even if I install any other rom I can flash it and get back with my original one, is this possible.
Please help, looking forward for your repiles

I'm actually very new to xda, I've been searching for about 4 days now and currently I'm reading other similar threats on xda. But I don't really know where or what to search for. All I want to do is update my phone without flashing it, also if it's possible to take a backup copy of my original firmware please reference me where to start. Didn't mean to bother or bug anyone here, it's just that I'm very new to this
No hard feelings
You need to root to bk up what you have now mate. 4.0.4 is the brick bug firmware not 4.0.3 . Do you want to root your phone.? Do you want to put a custom rom or Samsung rom on your phone?
Just go to sammobile.com firmware page.

maybe iPhone is better for you

Thanks for your reply, how do I root my phone and after I root it what do I need to download to backup everything. I don't really prefer to have a custom rom on my device but I have no problem trying anything on at as long as I have a copy of the original firmware where I can restore it back.

Thanks I'll check it out, what do I look for so I can make sure that it's compatible with my GT-I9100 device, or are they all compatible depending on which region I choose. Currently I'm in Egypt So whats the best firmware to download
Get whatever ROM you want.
Worst case, flash a new modem.
Sent from the little guy
Lsw is the new one. Uk base but as gastonw said it dont matter just download your modem you have now so you can restore it later "apriliam3 for them". To root get a dori ics kernel and flash that either with odin "tar" or in recovery "zip with sig" put on ext sd and update in stock recovery and that will give you root and cwm recovery when you have done that go back into recovery and do a nandroid bk up there. Get titanium back up in playstore and bk up your apps with. I link my contact's with google so they restore easily.
Just see chow to flash ROM's witch odin and choose ROM from Samsung development sub forum.
Thank you all for your replies,
I managed to root my device and advised by all of you, and I made backup using the cwm that was installed automatically after I successfully rooted it. In the backup folder that was created I noticed a file called "system.ext4.tar" is this the original android version that came with the phone because as I mentioned above I want to be on the safe side and have a backup of my original OS that came with the phone in case of anything went wrong then I can restore everything including the original current android version. Second step that I want to do is to flash my phone and install the jellybeans. I found two version version 4.1.2 which I know is compatible with the phone and version 4.2.2 but I'm not really sure if it's compatible or not. So what do you guys suggest I should install on my device
looking forward for your replies

A special thanks goes to andrewwright I prefer stock but I don't have any problems trying custom since custom gives more features
If you would tell me how to do both I'll be more than happy. I think both are flashed in the same way but correct me if I'm wrong
For stock sammoblie.com.
For custom gooim playstore app. Have you rooted yet? Mr1 milestone is a good choice as is solid.

Hey people of XDA
i've had loads of android phones in the past so i know my way around flashing custom ROMS but this is my first samsung device and this whole EFS thing has me a little pickled. i've read the efs info thread in general and just want to get some things straight before i try installing a custom rom/recovery etc.
Ok i've installed the samsung toolkit from the development section for rooting my SIII so I can grab the EFS folder and make a copy of it and place it on both my SD card and the computer, probably put another copy on the cloud just in case. after that i'll install a CWM/TWRP from the same toolkit and go to flash either PA or Cyanogenmod now this whole baseband thing to allow the EFS file to be picked up how do i know that the ROM i'm flashing won't cause any problems? last thing i want it is to bugger it up. those will be the main ROMS i use unless i decide to give those S4 ROMS's a try
oh the phone is a UK model and is on 4.1.2
Thanks for any help, very appreciated
So far its only the roms based on samsung mg4 or mg5 releases that change efs format. Expect all newer releases to do so also

So how would I know if said ROM has that? i'm assuming ROMS such as PA and cyanogen wouldn't be included which means i can flash those how many times i want without it touching that folder? what about this one http://forum.xda-developers.com/showthread.php?t=2311671
(EDIT) I guess not just saw a thread saying someone flashed PA and lost that folder. so no matter what ROM i flash through TWRP/CWM i need to manually restore that folder myself by placing it in the root directory?
last thing I want to do is bugger the phone up so i want to get as much definite answers first. since my phone already has 4.1.2 on it then only ROMs with a MG4/2 baseband would work right? so don't know how to tell that either.
iam thinking to revert back from cm 4.3 to omega/android revolution hd 4.2.2. can i directly flash this firmware. is there any modem related issues like imei no. change etc..
another query is, latest builds of omega/android revolution are based on 4.3. as i read there are lot of bugs in 4.3 tw rom. is this rom still contains those bugs? iam thinking to give it a try. but aftraid of imei change and those bugs.

4.2.2 is way older! the imei issue definitely raises after flashing it when downgrading from the roms released after july! samsung currently paused the 4.3 firmware for S3 and will resume sometime later!

or else can i try 4.2.2 with flashing mg2 modem.
thank you!!
Download ktool to back up your efs so you can restore if you lose your imei also install i file manager and run it under root and copy the whole efs folder just for good measure then back all this up to your computer

back up your efs every time before flashing. go through this link for any imei queries: http://forum.xda-developers.com/showthread.php?t=2393289
yes you can flash 4.3 based roms. they will have issues but minimized by the developers. no custom rom should be expected to be 100% perfect as the base itself has some bugs(you know). good luck
Rom
just flash rom and wipe it is easy
Hi,
I'm currently running Paranoid 3.97 (I think), but the phone is currently acting up. I'm stuck in the loading screen, so I thought perhaps I could use the chance to flash a more recent rom. I can't remember the exact baseband version, but it uses "EFS 1".
When flashing newer roms, such as Temasek's 4.4 or CM10.2 stable, would I have to upgrade to EHF 2 first? If so, would I need to flash a stock rom first, so as to upgrade the EFS, and then flash a new baseband (if not already included in the stock rom)?
If I don't have to, are there any real benefits of doing so? Or should I just use the EFS and baseband I am currenly on and forget about it?
If no to the above; would it make sense to flash the latest stock rom anyways (I guess 4.1.2 with EHF2) or is that just a waste of time?
Thank you in advance for any assistance!

AOSP roms do not touch modem/baseband and efs.
You'll fine.
"Trouble" lies in stock roms newer than MG4 (inclusive)
Thank you for clarifying.
Would there otherwise be any benefits of upgrading EFS and baseband?

Hi, there.
I would like to flash a Touchwiz Based 4.4.4 ROM for the International Version of Galaxy S3 (i9300). Currently it is running Android 4.1.2 stock rooted and TWRP installed.
So I wanted to ask aside from the regular flashing procedure if there is any other precaution to be taken.
I will definitely update to TWRP 2.8.6.1. Please let me know if any other file is to be flashed so as to avoid Bricking.
For Eg. Modems, Bootloaders or any other such files. Also feel free to suggest a 4.4 T/W Rom
Thank You.

Make a back up of your current rom,back up everything you need, wipe factory reset in recovery and install 4.4.4.
Make sure to read the instructions in the OP of the rom you want to install eg blekota note4

Thanks for replying sir. But are you 100% sure that I will not have to flash any modem before flashing Blekota. I've seen a lot of problems of people out here. Some losing EFS. Some losing IMEI. I do not doubt you at all but I would like to exercise precaution on my behalf.
Also My current Baseband Version as it appears in the Settings is DDELK1. So do I need to update it ? Also I won't have problems like Losing My IMEI or Simcard not being detected, Right ?
Thanks Again.
@x0nar: you're right. Flashing a custom-ROM with modem MG4 or newer will mess up your IMEI /net access. So go back to old firmware, fe ELLA, and update via OTA or KIES to JB 4.3. This changes your efs-data version 1 into version 2. Make sure, you have a modem N** afterwards. The you can root again and flash KK or LP-ROM.

Never Mind. Already ****ed it up. Flashed Blekota and initially I lost my IMEI. Flashed MJ3 Modem recovered it but no network. Says only Emergency calls Available.
Also flashed MG2 still no progress yet. And you know what the biggest problem is ? The device does not even belong to me. My friend requested me to update it and I messed it up. Any recourse ? The area of my residence is India. Could you please tell me which modem to flash ?.
Thanks
@x0nar: sad. Maybe your efs-data are currupt now. My only suggestion is to flash ELLA-firmware, hoping that OTA-update or KIES rewrite them.
The only right thing in the naive advice of Siberian Tiger is to make a backup. Did you? Then restore 1st.

Yeah. I did an EFS Backup. Even after restoring, the IMEI still was reflecting "Unknown".
But Never Mind, fortunately it gained a revival after Flashing the MJ3 Radio. However it would not connect to Mobile Network. So I flashed several other Radios and it's all set now and everything works just fine. Thanks for your help
@x0nar: then you belong to the lucky few, fine. But I meant a full backup of /boot, /system, /data. Do this before you experiment with KK.
