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,
Rizur (◣_◢)

As for the ROM, hyperdroid. It's very very smooth, no bugs, amazing battery life.

Thanks for your reply! I think those videos are a bit dated now and there is better techniques out now. I have definitely noted down Hyperdroid, I also recall it being quite popular too
Thanks again!

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.
EDIT 2: backup successful via CWM

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?

Hi I am very new in the android world. I have a Samsung Galaxy S2. I would like to prove custom ROMS and I have followed a lot of steps to prepare my device for this. I have download ROMMANAGER to backup my actual ROM (I would like to get it). I have flashed my recovery with ROMMANAGER and when I am going to do my backup my phone restart and get the following error:
-- Installing package...

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.

Greetings xda,
I wanted to COME back to complete 100% warranty from my current Custom Rom using a stock nandroid backup, after skimming the entire SGA Forum, I couldn’t find an all-in-one thread whichs contains a guide to regain 100% warranty including stock firmware, stock recovery, Unroot. I was even told that recovering to back to a stock backup is not possible if you have used an ext4 custom ROM. So I decided to handle this on my own. I hope you find this handy.
Flashing using odin might be easier but I bought my Ace from an Arabic region and i got the JPKP9 firmware. Unfortunately ,most samsung firmware websites lack the MODEM file of the firmware. So in order to address the issue I made this guide to enable people to restore their stock roms from a nandroid backup. Hence, THIS DOES NOT REQUIRE ODIN.
Table of Contents:
A). Requirements
B). Procedure
C). Tests
D). Credits
A). Requirements:
- Samsung Galaxy Ace (GT-S5830) [rooted]
- A stock firmware backup (you might have created this before flashing roms)
- eu.chainfire.cfroot.ext4manager-1.apk*
- Clockworkmod 5 *
- Stock Recovery files *
- Unroot.zip*
*: Inside “WarrantyRegain-UsmanJ.rar” (don’t extract the .zip files)
B). Procedure:
Step 1: Download the “WarrantyRegain-UsmanJ.rar” from HERE.
Step 2: Install the eu.chainfire.cfroot.ext4manager-1.apk file which you downloaded. Run the “ext4” application you installed, it might give you an error if you are not using CF-Root but don’t mind it. Scroll down and click “Convert to rfs”. Your mobile will boot into recovery, Wait for 10-20minutes as it will change the format of System, Data and Cache partition to rfs. Once over, your mobile will restart.
Step 3:Now go to Recovery and head over to “Backup and Restore” and and restore using the stock firmware backup you have. This will take approximately 3-5 minutes.One you have finished: Reboot phone. Congratulations, you have done 60% of the warranty regain process.
Step 4: Once you have restored to Stock Firmware, it is time that you now restore to Stock Recovery. Boot into Recovery again and flash the “Stock_recovery_S5830_2.3.x._by_ingbrzy.zip” you have downloaded. Once you have successfully flashed. Go to Advanced and Reboot Recovery. Now you are in the Stock Recovery.
Step 5: Now flash the Unroot.zip file you have downloaded earlier. Once you have successfully flashed, reboot.
CONGRATULATIONS NOW YOU HAVE GAINED 100% TRUE WARRANTY: Stock Recovery, Stock Firmware and Unrooted.
C). Tests
This method is tested and proved successful on the following Custom ROMS:
- StockLite v6 by tj_droid
- CM 7.2 RC1 by vo-1 (update 26/3/12)
- Bound to work on most ROMs.
D).Credits:
- Ingrbzy: for Stock Recovery
- Gganon: for unroot.zip
- Chainfire and KPK: for ext4 support app (I extracted rfsmaker.zip from it)
- Me: For compiling this guide (Just Kidding )
Don’t Forget to hit the Thanks Button as this is my first MAJOR post on xda.
EDIT: All those people who saying flashing using odin in easier, then let me remind you, i bought my ace from an Arabic region and i got the JPKP9 firmware.

After being awake all night i finally was able to restore my stock nandroid backup successfully thank to you.
And yes this method is important for those people who want to go back to what they previously had, in my case i updated my brothers Ace to JB 4.2.2 which after using for a while he asked me to revert it to what he had before{gingerbread} but sadly for me i didnt take any note of what kernel or rom his phone was running at that time and more importantly he needed all his whatsapp messages and other important data.
I only knew that he got his from uk but after going to samfirmwares i was unable to understand which firmware to download due to my little mistake making me more hesitant on what to do.
Finally after searching i found your thread and was able to restore the backup within 15 min
there are no words to describe how thank full i am to you for posting this thread

Hello,
My phone is not recognising in odin through download mode or in samsung kies, I have tried every possible way like changing cables, usb ports, computers, factory reset, but nothing was working, so then I installed cw9 on my samsung galaxy ace s5830i but still no success, now I want to go back to stock rom.
I had not taken any nandroid backup. Can anyone provide with a download link for the stock nandroid backup for Samsung Galaxy Ace S5830I, so that I can transfer it to my sd card and restore it
Thanks

GT-s5830i is not compatible with GT-s5830 model!!! They have different SoC, if you use the s5830 files could brick your phone!
Try to install a compatible rom with the compatible odin version of your device

I cannot install with Odin as it does not detect my phone in download mode. My only other option is installing stock rom through cwm, but I dont have the necessary files for my device S5830i to install it through cwm. Can u provide me with the files? It would be of great help.
Thanks
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.

I still have a few questions before rooting my phone for the first time.
1) if i root 2.3.6 using the right kernel, Can i still install an ics custom rom like resurrection?
2) if i root stock 4.0.3 Poland version or argentinian version, final result of installing a new custom Rom is gonna be the same because it completely replace the first one?
3) what's the difference between nandroid backup and cwm way to backup custom rom? Do i need to keep my backup inside the phone in order to unbrick it tomorrow, or may i just store it on my notebook and delete it from the phone?
Thanks a lot!!

1) Rooting is just to give you access to CWM.. ergo the ability to install custom ROMS so you can install ROMS after rooting
2) When you flash a new ROM (which is rooted) then you dont have to bother about what did you did before that..
3) If i'm not mistaken CWM only allows u to do a nandroid backup.. And if u want to restore to the backup ( in ur case unbrick :silly U need to have that in ur sd card :good:
Happy rooting.. Happy flashing..
1) Follow whatever instructions the rom you're wanting to use has to the letter.
2) If you install a custom rom, then yes, obviously it will replace any stock rom you flash it over the top of.
3) A CWM backup is a Nandroid backup. It's the same thing. You can store your backups wherever you want. I have my 4 most recent Nandroids on my phone, and I have every backup I've ever done on my phone stored on my PC (and another copy on an external drive I use for backups). So I guess the question you're asking is, can I take a Nandroid backup from ages ago stored on my PC, put it on my phone & restore it. Am I right ? If that's what you're asking, the answer is yes.
Thanks. Actually i was asking in case my phone bricks after installing a new rom. I guess i won't be able to come it back to life if i don t have the backup in the phone.
And one more thing. What is efs backup. Do I also need to do it?
Thanks
Sent from my GT-I9100 using Tapatalk 2
Yes. The 2nd thing you should do after your root your phone (first thing is do a Nandroid backup) is to get kTool from Google Play & backup your EFS. Before you install another rom or kernel do both of those.
Keep a copy on your external sdcard & keep another copy on your PC. Just in case you ever need it. We get quite a few people on here every week with IMEI/EFS details gone & most don't have EFS backups.
thanks!
I forgot to ask, is there any real risk at using triangle away app? So far, is it working on any kernel? thanks

I've actually used that app a few times well (about 5) and haven't had any issues but once you get CWM installed and you flash kernels through it you won't get the yellow triangle.

There will always be a risk when using anything that manupulates root access, but triangle away is quite safe, as for what kernel if works on, most kernel threads will say if it is compatiable or not, but only with ICS kernels, not GB kernels.
"...once you get CWM installed and you flash kernels through it you won't get the yellow triangle."
What do you mean by that? I actually don´t need to use the app, because triangle will dissapear anyway after flashing a Kernel?

You will still have the triangle after flashing a new rom or kernel, the best way to get rid of it is triagle away, this app will also reset your flash counter.
Once you get a working CWM, let's say you're using Cyanogenmod 9 and you want to flash over the stock kernel.
You'd put the kernel file on the memory of the device (sdcard) and boot in CWM recover and flash from there and you won't get the triangle.
The triangle won't go away now if you unless you use a USB jig or the triangle away app. So get rid of the triangle now and when you want to try a new kernel flash it through CWM and the triangle won't appear. Flash a kernel through download mode and you'll get the triangle.

Fixing permissions is automatic I believe in CWM recovery. It's an option in the recovery menu. Remember to wipe data and cache (dalvik too) when flashing a next rom or else you won't be able to boot.

Thanks for the info mate
By the way, you should really just buy a USB Jig off eBay for a few quid, it resets the custom binary counter (on old bootloaders) and can also force your phone into download mode after a bad flash. Handy to have around. Also, now that you have rooted your phone, download EFS Pro (found here on XDA) and back up your EFS folder before any flashing. Lose this folder and your in serious trouble!

Hi! When rooting or flashing a custom rom or kernel, do I lose internal sd card content?
Where is the EFS folder I need to backup?
Thanks!
Hello. New to rooting. Root worked well, cool stuff. Then i tried to flash a rom,(probably never again) cyanogen rom said it was unstable on the s3 but i saw posts of slimrom(.net) and it sounded steady.. now i cannot unzip files or flash roms or get any gapps to work. Softbrick i guess its called. Plus my backup isnt on my phone anymore. Do i need to Kies my way out? Any help would be dope. I never thought id want touchwiz so bad. . . Also if kies works will my google apps be back?

Like JellyYogurt said we need more detail your post is confusing this is probably a easy fix and you need to read up more on how to flash roms.First of all there is nothing wrong with slimrom I have flashed it many times without any problems..."unzip files" why would you want to unzip files to flash a rom?
Rom's come in a couple of formats zip files which you flash with a custom recovery ( you do not unzip them) or .tar files which you flash with odin (these are normally stock roms).
Can you get into recovery? (If yes perform a factory reset and reboot ) see if that works,if not you mention you have a backup can't you put your backup on ext SD card with a card reader and restore from recovery or do you mean you delated it ?
If you just want to go back to stock touchwiz and not bother with custom roms again just download your phone version from sammobile and flash with odin.Also another misconception is that you said you rooted then tried to flash a rom why? You only need to root your phone if you are going to stay on stock rom and use root apps and not flash custom roms. The reason is 99% of custom roms come already rooted so you can skip rooting your phone yourself.

I flashed the rom using the instructions on slimroms.net. but i think i didnt 'wipe data and cache'. the unzip thing is an example of how unstable it is. I can go recovery. But my comp is broke so i didnt get ro go to sammobile for the files. I created alot of backups with titanium but it seems they are all deleted (didnt move to another device, live and learn). Thanks for the speedy assistance. Ill try odin and sammobile tonight after work. Just figured out how to go back into recovery mode after i made this post.
You have to do a wipe data and format system as they said. Guess u didnt do both?

Ok... Let us know how you get on.
Also titanium only backups up system and user apps it is not a complete backup of your system for that you needed to do a nandroid backup with your recovery (if you don't know what that is there are some stickies threads explaining what it is) Good luck.

Okay. Got it. First I had to go to my slimkat settings and check root access etc, thats why nothing worked. then I kept trying to unzip the gapps folder, not knowing it had to be flashed also(stopped reading right before that in the instructions, oops). After i flashed the gapps i could get into playstore np and its running smooth. First rooting attempt alittle panicky but my s3 now has 11.01gbs of storage and all the apps i really need. Thank you both for the quick reply. Sorrying for noobing out back there. Im starting to understand alittle more. Im going to read on back-up/recovery and hopefully be rooting this Gflex on Tuesday.
