Question about EFS - Galaxy S III Q&A, Help & Troubleshooting

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.

Want to try out some custom firmwares, but want to be safe at the same time

Hi guys...
I have a galaxy s3 and up to this point I've been pretty satisfied with the original firmware...
However, I'd like to try out some of custom made ones, but since there's a big update on the way, I want to be safe doing so...
What I mean is basically this:
Can I somehow backup my stock firmware, try out some custom builds and then get the OTA update when it's available?
I don't really care about guarantee, but I'd really like the option to get OTA updates from samsung in the future (if I for some reason want to do so).
I remember an old post, where someone talk about this, but I can't find it
Please help me
Most definitely. You can find stock builds here in this forum and simply flash using ODIN to get back to stock firmware when you want to. Be advised this does wipe your data so have a good backup of it before hand.

And then it would be as my phone never were flashed and OTA and other samsung only stuff would work?
You will have to use triangle away or something like that to reset your flash counter if you want to send your phone to repair and make it appear as you have never flashed before but unless you break your phone, don't bother. And yes the other Samsung stuff should probably work.

If you flash your phone with a custom ROM for instance Resurrection Remix or Cyanogenmod you'd not directly be able to restore a stock ROM.
You will have to find one http://androidfirmwares.net that's for your region and flash it through Odin. Then you'll be able to update OTA and KIES.

i had the same fear of loosing my data and stuff so you can wipe dalvik cache and cache partition and flash omega ROM for ur S3 and welcome to perfection.
Ps. Flash with Siyah Kernel for battery craziness! ! !

You mean restoring from a nandroid? Because I was able to restore ICS whilst using JB - I did it multiple times.

Agree the advise given was plain wrong .
Nandroid restore a backed up stock rom yes yes yes .
The only but is that the backed up rom is of course rooted .

Okay... now I'm even more confused
Let me see if I get this right?
One way to do it would be to:
1) Download tools and rom (odin, CM and drivers etc)
2) Flash new cool rom
3) Donwload original samsung rom
4) Flash old boring rom back to phone
5) Use tool to reset counter (optional)
Now, my phone would like as if I had never ever rooted and flashed my rom
Is that more or less correct?

When you want to get back to stock firmware follow these steps
1.Download stock firmware for your region from
Www.Samsung-updates.com
2. Download triangle away from xda forum to reset your flash counter from

[Q] A few questions about rooting and custom roms.

Hi
Im new to rooting phones and have rooted my Samsung galaxy s3 GT-I9300. Im running 4.1.1 on it and rooted it using odin and CF-ROOT-SGS3-v6.tar.
Ive got CWM manager and superuser on it and have backed up my apps using titanium back up and backed up the rom using ROM manager.
What I want to know is can anyone recommend a ROM that is like the stock one but with added features such as multi window and takes away a lot off the added Samsung stuff thats not really needed and also runs smooth without eating up too much battery?
Can I just update my kernel or do I need to install a custom ROM?
Can I install the new ROM using ROM manager?
Do I need to move any backed up apps and current rom off the phones memory to an external SD card before installing a custom rom?
Do I need to take into account the Baseband version (mine is I9300XXELJ2) when looking what roms I can install or does it simply have to be for the S3 I9300?
Sorry if my questions seem a bit daft or if Ive not given enough information. Im new to all this and want a custom rom that will hopefully offer a bit more than the standard one but dont want to brick my phone
Thanks in advanced.

I would recommend sotmax ROM or android revolution ROM which is both close to stock ROM and my favorites. But you have to try for yourself to know.
You can use custom kernel after rooting. But read the op to see if compatible.
ROM manager can install ROMs but only with the premium version if I'm not mistaken. Alternatively just use cwm to flash. Fast and easy.
Backup apps depends on what you using. Titanium backup? Usually backed up apps are safely stored. And can restore in any ROM after flashing.
Baseband usually will be along with custom ROM.
All in all if you read the op in first post of each thread and follow steps. Bricking is usually a non issue. But as always make a full backup before flashing.
Happy flashing

No need to move the backups anywhere unless you're gonna wipe your internal SD.
Baseband doesn't matter, just flash anything for the i9300.
And don't ask for best ROMs, it's against the rules

So does the baseband in the rom have to match the one on my phone or can I install any rom and my baseband will just change and all will be fine?
This is going to seem stupid but what do you mean by op?
To install or flash a rom using CWM do I just click recovery mode in the app and continue from there?
Thanks for the quick response,
first, read the basic guides.
op means the first post

You can't have Samsung features on an AOSP (aka stock Android) based ROM. Its integrated into Samsung ROMs.
For best of both world's you can dual boot two ROMs using Siyah kernel 1.8.9 eg. A Samsung ROM (ex: stock) and an AOSP based one (ex: CM10.1)
Before experimenting copy backups to an external SD card or your PC.
International S III 16GB / Dualboot 4.1.2 Stock & Cyanogenmod 10.1 / Gokhan's SK
Anono ROM gives high performance stability and great battery life
Other than that it is like stock

[Q] Samsung galaxy s2 firmware problem

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.

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

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.

[Q] Advice needed for rooting GT-I9300

Guys I know this is long but PLEASE don't freak out! I really need some advice from you experts on this! I hope you could spend your time reading everything here and give me some advices! Thanks!
Phone details:
Model number: GT-I9300
Android version: 4.3
Baseband version: I9300DXUGNB1
Build number: JSS15J.I9300XXUGNA5
Hello guys, since I'm not really a rooting expert (previously I rooted a motorola device), I would like to ask for some advices regarding rooting our S3 because I have only one phone and I can't afford to brick it.
1. So basically I'm referring to the guide here. However, that rooting guide is for Samsung Galaxy S3 on I9300XXUGNA7 Android 4.3 Jelly Bean, which is different from my build number (I've checked software update on my device over OTA and Kies3 but it says I have the latest firmware), will it works for my phone? Also in the guide it says to use odin3 v3.09, however in CF_auto_root page here it says to use odin3 v1.85, so which one is working for my device or which one is better?
2. Next I would like to ask is it necessary to install CWM recovery to replace the stock one? After searching around, I found that there are some people who installed CWM recovery even before rooting, is that even possible? So basically to install CMW recovery I think I will follow the steps here, is this working for my device?
3. Okay I know this is the dumbest question... but is there anything else I need to do after the above 2 steps (flashing kernel, modem etc.)?
Thank you very much for spending your time reading my post. I hope you can clear those doubts for me!

Flashing your phone in any way doesn't guarantee not bricking it, see this thread
Scroll down to the quoted section headed Quick Root from there
Download Odin
Download CF-AutoRoot for your phone
Read the link on rooting
It is really straight forward just read up on it but don't read too much into it a frighten yourself

Great that thread helps a lot! I cleared most of my doubts now, but one more question please, after rooting, I wished to install ported apps like S5 launcher and accuweather, and in order to install these I need to flash from recovery. Is it possible to flash this using stock recovery? Or I need to install custom recovery like CMW?
You can't install anything with stock recovery, you'll need a custom recovery.
Make sure you have a full nandroid and efs backup before you flash anything -ported apps can break the framework and produce bootloops.
Seriously though, all this information is available in the sticky or by searching -why do need people to write it all out for you?

Thanks for your information. I did search around and try to understand the things myself, but still there are some doubts remain, that's why I opened this thread hoping that someone can clear the doubts for me. This is my only phone and I really can't afford another (I'm from a low-income family), I just want to make sure everything is alright so that I don't mess up my device. Thanks for your understanding
If this is relevant for Samsung galaxy s3, I got this done the other day using Odin to unlock and root, ran the root app to confirm root. The ROM manager to found CWM recovery flash. So far all good, should take 5 mins in all but an hour in prep and homework.

Don't use rom manager, it can soft brick your phone.

Hello! I agree that it would be better NOT to use Rom Manager. Many users had problems because of it. The safest way, in my opinion, is to flash a custom kernel using Odin. For example, I had stock rom and used Odin to flash boeffla kernel (not advertising it, just saying what I did) because that kernel had both a .tar version and a .zip one. I downloaded the .tar version and flashed it with Odin by putting the .tar file in the PDA column. That's for root.
For recovery I'm using PhilZTouch and I love it. It supports both JB and KK roms and that is preety cool. Also it's full touch so I don't need to stress my hardware buttons. It's also available as .tar file so you can flash it with Odin just like the kernel.
That's how I'd recommend anyone to root and install a custom recovery on a Sammy phone because I believe it's the safest way. PS: before launching Odin make sure the phone is NOT connected to the PC and that Kies isn't running in the background (use Task Manager to check) Goodluck! !! :thumbup::thumbup:

Thanks! Will check out PhilZTouch recovery :fingers-crossed:
Currently struggling with deodexing/odexing the stock rom, after reading around I can differentiate between the odex and deodex rom, still digging on how to deodex a rom though (since I want to install some S5 mods). After searching around, it seems like titanium backup can do the deodexing/odexing just nice Gonna do some more preparation, hopefully I can have my device rooted by this week
You could flash PhilZ Recovery and make a nand backup of your rom. This way you'd have an emergency copy if something goes wrong or if you break something in the system. Just my thought

[q] flashing 4.4 from 4.1 ?

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.
