Hello!
I want to change my ROM because TouchWizz UI sucks and my device is lagging... I like CM and I want to flash it on my S3. I want to install it via CM Installer, but I have some questions :
- Does CM have Gapps already installed?
- Should I backup the /EFS folder? And how?
- Give me a way to backup my Stock ROM, if my installation fails, I will go back to it. (A tutorial or smth...)
I know how to install CM via their installer, but I am worried about that EFS thing...and the backup also...
Thanks!

I tried to use the CM installer but it gave me an error, If i where you just flash it through CWM or TWRP its much easier (for me that is)
When i first flashed my I9300 (S3) i never backed up the EFS i just never felt the need but i had been flashing roms for around 2 years, but for a beginer it may be wise to back it up.
Also If you want to backup your stock rom you can create a nandroid backup or just backup your info and if it goes wrong then you can just flash it back to stock 4.3 through odon.
Hope this helped?
Let me know how it went.
Well... I need to backup my /EFS and my current stock ROM. Is there any way to do it without rooting or other complicated things? And also I need to know how to restore that backups if something goes wrong... I will install CM via CM installer as I said earlier.
Check this out.

How do I backup and restore /efs?
There are a few methods to backup /efs, but they all require customisation of your phone. Either root access, or a custom recovery. I appreciate that many of you do not wish to root your phones and just want to flash official ROMs via Odin... Well here are your choices:
Only use OTA or KIES to update (Official Method)
Root using CF auto root / Framaroot - backup efs and THEN flash via ODIN
Flash a custom recovery via Odin, backup efs and THEN flash a ROm via Odin
Risk it. Don't backup efs. Simply flash via Odin and hope for the best
...and here are the options for backing up / restoring efs (this list is not exhaustive)
EFS Pro - App needs root
SGSIII EFS backup / Restore - app runs from Windows / Linux and needs root
kTool - app needs root.
Philz advanced CWM rewcovery - custom recovery can take efs backups using the "Custom Backup" feature.
It's worth noting that some custom ROMs will give the option to backup efs, but you can never have too many backups!
Oops

I forgot to say about Philz recovery amazing recovery i advise anyone to get it but yeah this will work to backup the EFS but you have to be rooted.
If you are rooted you can use Ricky's tool to backup your efs

Meh... I will root the phone with CF Auto root, and then use kTool to backup the EFS. It will create a folder with 2 img files, and I will save that folder on my PC... IS THIS OK?
To backup my stock ROM, what should I do? Give me some ways to do it...

OK... Then I install CM via CM installer. And unfortunately, it says "No network" and i have the generic 0049 IMEI. What to do in this case?

Hey everyone!
So I have done just about all I can with the SGSII and have decided it is time to do some upgrades, ie root and eventually a custom ROM. The reason behind this is to remove bloat and customize to exactly how I want
I have updated the firmware once via Kies to v2.3.5 and here is a screenshot of the infos.
I am also using a UK 3 (Three) branded handset with the 3 bootscreen and a few unsavory apps that was preinstalled that I would rather not have there
I would like to use SpeedMod kernel which I believe is compatible with my phone and is available from here.
Now for the questions and I'm very sorry if you have heard all this before. It's just that this forum is HUGE and I have tried to gather the info required but I just need a steer in the right direction.
1) Do I flash the SpeedMod kernel via Odin in the same manner as described here in Chainfires thread under long instructions?
2) Is the linked page above for SpeedMod the correct version for my phone?
3) If so, great! If not, then what is the best method to flash and which is the correct kernel?
4) Also I'm under the impression that this is what will give me root, is that right?
5) This one is probably more down to personal opinion, but in your opinion, which is the best and most stable ROM with everything working? (If such a thing exists atm of course)
Many thanks for reading this post and once again I am sorry for the noob Q's, but I guess that is what defines me as a noob in this area
I look forward to seeing your replies,

No such animal ever if their was then it would be a one rom forum .Plus devs change the rom all the time .Having tried every rom going the major difference is not speed or better battery life just theme .
Root and CWM gives you backup so you backup the custom rom you are using flash another dont like it clicky click back to old rom .
First rule backup EFS
Second rule backup
Third rule read and dont flash until you are comfortable with what you are doing .

Yes this the first Rule backup the EFS, you can use the HK-Tool its on the Market
Thanks for your replies guys but am I correct on how I install the speedmod kernel to get root? Or should I go with the full chainfire method?
Yes I agree that when it comes to roms and personal opinions its more theme orientated but I was trying to get at people's faves. Take a good curry for example, they come in many flavours but my fave is a hot madras, and which may be too hot for some or maybe not as flavoursome as some would like, I believe the same for roms , crap analogy but I tried ;-)
Thanks everyone.

You want to install speedmod so you follow the instructions in that post .

There is unfortunately (as far as I can see) no instructions for installation in that post
I think I may just go for CF, seems like the most popular.
Now to make some backups etc and read MOAR
Any more info that anyone can chip in is very appreciated.

With even more thanks to you jje, I have found this which was only a couple of links deep hehe
I have backed up my 300+ photos (the only personal stuff I'm really that bothered about because it contains pics of my son who is now 5 weeks old ) but all I can find to back up the EFS is for after root. I tried HC-KTool but that needs root access. Am I right in thinking that the first step is to root via the kernel and THEN make a backup?
Yes CWM and root .
http://forum.xda-developers.com/showthread.php?t=1103399
Or if Speedmod kernel installs root just follow his instructions via ODIN .
Then backup EFS folder
Then In CWM app backup phone .

Thanks mate, I went ahead and flashed SpeedMod and I followed the guide to the letter and read up on so much, I'm now rooted
I have also made a backup of the EFS, here's the screenshot's 1 & 2 of backed up data and my kernel version. I used the KTool to do the backup.
Is there anything else I should consider before proceeding with flashing a ROM?
Many thanks, Rizur.
PS you da man JJEgan
EDIT: Oh and I need to do a backup with CWM I believe.

You are pretty much set, pick a rom and flash away, copy the EFS backup to your computer as well to be safe.
When you flash a new rom you will need to wipe /data aka app data (not sd card eg pics etc) So you may want to backup any game saves etc with titanium backup.
You shouldnt backup/restore system apps with titanium as it may/will cause problems.
As far as choosing a rom, I find hyperdroid to be good, villanrom to be good as long as you dont "need" the newest base, but you can try a few and see what you like.
Thanks mate
Having a big problem now I decided to go for CheckROM as my ROM of choice, I followed the instructions to wipe the device and to put the tar file on sdcard and flash via CWM. This went ok but the flashing took all of about a minute and half, prompted to reboot and now I'm stuck at the screen with the yellow triangle.
I had to pull the battery after about 45mins as this was the only way to turn the phone off. I did backup via CWM and I did backup the EFS with KTool but CWM is finding nothing to backup from
Please some kind soul, help me out with some advice
Flash back stock firmware should do the trick.

This happened with me once and I was a total noob back then. When you're stuck at that triangle, press the power button. If nothing happens, keep pressing it. Worked for me. Felt like such a prat waiting 30 mins for it to boot
The yellow triangle turns up when you root the phone and it wont effect your phone at all, will work just the same.
Hope I helped
I have now downloaded stock firmware from here, do I put that folder on sdcard or remove the .mdf file onto sdcard?
EDIT now I realise i need to perhaps install via Odin, in which field does this md5 go in?

Any amount of searching would have told you that you can't install CWM recovery with ROM manager on the I9100, therefore you have stock (3e) recovery.

So, I am very sorry if this disturb someone, please forgive me.

What means "you can't install CWM recovery with ROM manager on the I9100, therefore you have stock (3e) recovery.

Thanks in advance!
If I read your OP right, it seems you have installed Rom Manager on your phone in the first instance, without rooting it first. Am I correct ?
If that's the case, it won't work. Rom Manager only works on rooted phones, normally to do this you'd probably use CFRoot to root your phone. However, if you root your phone using CFRoot, this will install CW Recovery, which as Oinky has quite rightly pointed out is not compatible with Rom Manager. Rom Manager tends to break CW Recovery.
So what you need to do is root your phone. And you need to decide which method you want to use to root your phone. If you really want to use Rom Manager you'll probably need to use Zegrush or SuperOneClick (anyone feel free to jump in & say/correct me if either of these installs CW or won't work for whatever reason) to root your phone rather than CFRoot.
On the other hand, if you're happy to go without Rom Manager and want a quick and easy way to root your phone, then CFRoot is the go. This will give you CW Recovery, and all you have to do in order to flash roms & kernels/make backups & restore is to boot into CW Recovery.
As Oinky has suggested, you definitely have a lot of reading to do, do a search for CFRoot, Zergrush & SuperOneClick on here.

Thanks MistahBungle for your answers. Perhaps I didn´t describe the problem very well... Sorry! Anyway, I have rooted my phone with "Unlock root" aplication.
After this, I backup my efs folder, and my aplications with titanium backup.
Now is the moment I would like to backup my actual ROM. For this I would like to use ROMMANAGER (because is the suggestion of the forum I followed).
I did the recovery flash manager ok, but when I tried to do my BACKUP ACTUAL ROM my device rebooted and give me the mensage that I have told in my first post.
Thats my situation. I would like to backup my ROM and prove another one, but if I had any problem with my SGS2 I would like to have all my backups to restore before go to the tecnichal service.
Any idea?
Thanks!
OK cool. I understand now
Sorry, I don't use Rom Manager so I can't help you with your problem. I rooted my phone with CFRoot & have always used CW Recovery (and Titanium/kTool) for my backups. Hopefully someone comes along soon who has experience with Rom Manager & can help you with your problem.

AS suggested, ROM manager is not compatible. Get rid of it. Flash any CF-root CWM kernel .tar with Odin.
Ie. Chainfire CF-root or siyahkernel
All problems solved and nandroid backups and restore capable.

Hi! I did it! I have installed this morning my first stock rom and my first custom rom. All works ok.
Thanks for the information.
I have a question (if I have to open another post, please tell me). I have installed one custom rom but I don´t like so much so I would like to try UltraToxic rom. I know that I have to start installing a stock rom before, and after install UltraToxic 8.2 by Odin. My question is that I don´t know if I have to install again the CF-KERNEL that I installed before when I installed my first custom rom. Is this kernerl overwritten by the custom rom kernel?
Thanks a lot !
Yes. If you install a custom rom it will overwrite your existing kernel with whatever kernel is packaged with the rom. If you really prefer the CFRoot kernel, you can reflash this over the top of whatever kernel is installed when you flash the rom (or you could flash one of the other kernels you can find on XDA). That's up to you.

Thanks for your quick answer. I will do it again. I will install again CF-KERNEL due to I don´t know very well how kernel works and if one kernel is for one specific rom, so I will recover my old kernel and then I will install again the another rom.
Could you recommend me a good rom to install? I would like your opinion, if you consider it ok.
Thanks
No, you don't "have to". Custom ROM will come with a CWM root kernel, CF-root, speedmod, Siyah, etc...
You can flash back CF-root if you wish, but don't "have to".
Just be aware that nandroid backups made with a particular version of CWM may not restore with another version. Ie. 4.xxx -> 5.xxx
Now you have root, make sure you have EFS filler backed up. Many ways to do it;
Hellcat ktool
https://market.android.com/details?id=net.hellcat.droiddev.ktool
Or,
GS2 Repair
https://market.android.com/details?id=com.helroz.GSII_Repair
You'll have an expensive alarm clock if your IMEI ever gets corrupted, so store the backup on a PC too.

I have backup my efs folder from my original ROM. Do I need do it again? Do my efs folder change every time that I flash a rom?
Another question is that with CriskeloRom and UltratoxicRom I have a problem with Titanium Backup and it is that I can´t restore every data that I have backup because in any part of the restore Titanium Backup gets into an infinitive loop and does nothing.
What could be the problem?
Thanks for this new information! This is a great forum ! Thanks for support!
If you're trying to restore system data from one rom to another you will run into problems.

No, EFS won't change unless corrupted. So you won't have to backup EFS every time.
As post above, aas general rule, don't restore system apps and data (red)., especially across different ROM and Android versions.

Hi guys,
Firstly apologises in advance, I'm using my phone to browse so trying to navigate what I need to know.
I be using this guide to root, I read it several times and it makes sense for me.
Before I root though and this is a huge factor, is there anyway I can save all my current apps and restore them after flashing a new rom?. I know titantium backup does this but you need to be rooted to achieve this and before you root I understand you need to have a clean wipe for the phone which I haven't done yet since I'm hesistant reinstalling the apps all again 1 by 1.
Thanks

T-mobile UK, right? You have an I9100?
You can use that guide, sure. But I find CF-root to be even easier, as you don't need to use an outside application. Just flash the CF-root kernel for your build of android. Done.
well i frankly neva did a wipe or wat ever i jus rooted ,flashd kernel ,roms......but one thing i neva forget is the efs folder to backup......
root ya phone no prbs,,,,afta tht backup efs using hellcat tool(free app) and its a good idea to save a copy on pc to..now rooted--u can backup ur rom...or flash kernel but go for the stable ones

Thanks, I'm still new to this trying to understand everything before rooting.
So backup efs?, what is it and does exactly.
I was under the impression that once I should pick the kernel closest in the about section?.
you will only be able to backup EFS after the rooting...
first Root with Cf-root then the first thing you do EFS back using Ktool (search on google play)
You'll be amazed how easy it is once you've done it (I did it a couple of weeks ago). It's all available right here.
Pay particular attention to this when choosing the kernel:
Listen closely, for I will say zis only once!
Go to Settings -> About phone -> Kernel Version. Note the string present there:
2.6.35.7-I9100XXKG1-CL349526
What matters most (KG1) in this case, is in bold. Try to find the matching file under downloads:
CF-Root-SGS2_XX_OXA_KG1-v4.1-CWM4.zip

Good luck dude, let us know if you have any questions.
Thanks UK, so CF root it shall be:
Instructions - ODIN (short)
- Flash CF-Root-xxx-vX.X.tar (from the attached zip) as PDA in ODIN, without repartition. Done.
Correct?
Then how does one flash a rom?.
Yes, you flash the TAR file in Odin.
Flashing ROMs comes after you have rooted. First, you put your desired ROM zip in the root of your internal sdcard. Then once you have installed a CF-Root kernel, your device will have ClockworkMod (CWM) Recovery. You access this by holding Power+Home+Volume (Up) until your phone reboots into recovery mode. Then you simply follow the instructions to flash the ROM (read instructions from the developer and always backup).
^Well that's for custom ROMs. If you're talking stock Samsung ROMs, there are many guides around for installing those.

Ok makes sense.
So flash tar file with Odin giving me Root Access.
Grab the desired Rom, so for example MIUI then can you elaborate on the kernel. Because this is the one things that bothers me the most because I can't get my head around it.
From reading I need to get the kernel closest to the one on my about phone info correct?.
Yes that's right. As in the example, where the kernel version says I9100XXKG1, you find a similar one based on the KG1 kernel.
Ok all makes sense, thanks for all the help.

You should read the guides and faqs everything is posted .
EFS is a backup that allows you to restore your phones EFS folder that contains the IMEI for your phone . Its rare but possible that flashing may break IMEI leading to no network connection .

It's always a good idea to backup - search on the market for some of the best solutions. But honestly, I just winged it the first time I rooted with CF-Root, and went without backup. It's up to you.
But after you have rooted get kTool off the market and back up EFS, put it in the cloud or on your computer so you don't lose it.
Custom ROMs normally require a full data wipe first time flashing, so get titanium backup pro and backup all your apps from there.

Hello all,
I have a GT-I9300 with android 4.1.2
Is the path I am now going to take correct:
1. Use [GT-I930x/T/N][SHV-E210*][SHW-M440S] CF-Auto-Root to root the phone.
2. Use Rom Manager to install Clockworkmod Recovery Touch.
3. Backup EFS, what is the best method?
4. Backup all other partitions
5. Install [CM11][4.4.2][i9300][ROM][KERNEL][DEC22] temasek's UNOFFICIAL Build - V23.
So my qeustion lies in number 3 the EFS. Is there anything else I forgot? Will backing up with CWM be enough to return to my exact state now? (Stock Sammy 4.1.2)
Like I had before with another device, when you plunge into the world of flashing there is alot of mixed up threads. Did I find the correct order?
Also, Baseband/Modem/Rils still a thing to mess with on S3's?
Using the wrong CF autoroot file will brick your phone, make sure you use the very specific i9300 one.
You need to go read the basics, in general forum stickies -follow a guide and make sure you read carefully before you flash anything.
Use philz recovery, it will backup efs as well.
make sure that you use files that say i9300 on it, anything else will brick your phone. Backing up EFS is a must. Do it with ktool after rooting. Then just install the rom of choice and your done.

I would suggest to flash a stock 4.3 first with efs v2, with compliant modem, then cm11.

Thank you all for your answers! I will make sure to double/triple check that I have the correct CF autoroot. I prefer using CWM recovery so I will use that in combination with ktool after I rooted.
As Zoleegee commented It would be wise to flash a stock 4.3. However there is no stock 4.3 for The Netherlands...
How should I proceed?
Will following this get me were I want to ~> [Official Firmwares] I9300XXUGMK6 (Android 4.3) - United Kingdom (BTU) [18-12-13] ?
My main concern is that I want to make sure I do not run into cell-reception isseus.
Any thoughts?

Yeah it will do no problem. Also Search up mega wipe for the s3, flash that before you flash your rom. Super clean phone then to flash cm11 off

The easiest and safest way to backup efs.
I'm in big trouble...
I was on Cyanogenmod 10.2 for a long time, but yesterday I choose to upgrade to CM 11. I did a backup in case thing went wrong and did the update. And it did.
After update I've started my phone and I had no service/reception. So I went to restore my backup. I did this a few times so I was pretty safe about it. When I've tried to restore my backup, didn't work. The restore file didn't do anything but it clear the access to CM 11.
After that started a lot of research on the web for solutions.
I already tried to flash the firmware to stock, using the firmware from Sammobile. Now I get the no IMEI error.
I can't find any EFS folder or backup folder. I can only find the EFS folder but it's empty. I've used the Root Explorer to try and find this folder, but can't find it.
I already read some topics about the same problem but I can't find any solution that work for me.
Can you please help me?
Thanks
