Hi all
Just got my new phone and WOW! Had a Desire which was rooted via Revolution, phone was s-off with 4ext recovery,CWM, TB, Bootmanager and other apps which only installed if rooted/s-off.
I have looked at a load of threads and seem to have got bogged down with with what rooting process to use; CF- Root, DooMLord etc
Thinking of rooting new SG2 through DooMLoRD's Easy Rooting Toolkit v4.0. mainly because it has an unroot process but have a few questions peeps.
1. Is the rooting way I am thinking best way for root?
2. It says in the title easy..is it?
3. What do i back up after root? or is it just a nandroid with 4ext/CWM?
4. Can above mentioned apps be installed after root?
5. Can any Roms and/or Kernells be installed from the SG2 posts or are there certain ones for whichever way you rooted? Any recommendations?
6. If it all goes pear shaped is the unroot process safe for back to stock?
Thanks and have a good evening

1. You can use ZergRush if you're on 2.3.5
2. It's simple
3. You should do a nandroid backup and backup your /EFS folder
4. CWM can be used if you install a custom kernel (it has a modified CWM for galaxy), everything else yes
5. You can install any kernel as long as it's not for ICS. It will bestated so in the post
6. Unrooting via zergrush is just doing a full wipe and all traces are gone. If you use a custom kernel then your counter goes up and you'll need to flash a stock kernel and erase th counter via USB jig if you want to retunr the phone or bring it to a service center (else you void the warranty)
Thanks for prompt reply bpvik.
Did really want change kernels in case I messed it up. Btw why not use any ICS kernels? And how do I get back to stock after kernel?

The one-click root process only replaces the custom recovery, and from there you can immediately make what is called a "Nandroid" backup. That will make a complete backup of the regular OS & user data on the phone. You do this step immediately - the first time you use the Amon_RA recovery.
Without root, there is no way to back up your phone completely; you need root privileges to do that.
That means that if in the future you wanted to "return to stock behavior", you could simply restore your first Nandroid backup. The phone will work exactly as a stock phone, but of course will not be a "pure" stock phone because it will still have a custom recovery on it.
If you decide to return to 100% stock you can use the "FlashBack15 v1" ROM, available here on XDA.

I have galaxy sii GT-I9100 and I want to revert back to stock so i can cleanly install the new RR rom. Any help would be awesome. I was quite knowledgable with my old samsung infuse 4g, but this phone is a lot more complex than that one so please simple terms if possible
If you go to samfirmware download your desired rom then flash it in odin via the PDA section. This will return your phone to stock, but you will loose root. All the best.

If you want a fresh start just format system whilst performing your wipes. Only do this with a safe kernel as anything based on stock 4.0.4 will brick your phone. When I ever change ROMs I just run wipes and format system then flash my chosen rom. That is the correct site and you can flash any rom for your phone regardless of region. EFS back up is a separate tool which you download on to your pc which then backs up the EFS folder. There are other apps that do this too. I use them all, can never have too many copies of it.

So if I just do all the wipes, it should be all good? There is a lot of files that I don't want if they don't belong to my rom, should I delete some or what should I do? The basic thing I am trying to do is only have files from apps that I have and ones that the rom needs.

I understand what you're after factory reset, wipe dalvik and format system will give you a clean installation in terms of rom. If it's a complete wipe you can wipe the sd card from setting /backup and reset. But this will wipe music photos too. Once rooted you can always browse the directories and manually delete any unwanted files/folders. Please check your kernel first.

How to stock > custom rom > 100% same stock?
Hello,
did not want to start new thread with same name, but my question a little different.
So I bought S2 and I would like to play with some custom ROM of course. Not my first Android phone, but new phone new unknown things.
I read many post, but it is still not clear if I can make my stock rom and kernel backup, then root it, have some fun and if I need just restore stock rom and kernel and every thing would be as it was new?
I understand how to root and this CF-Root in Stock Recovery method looks like can do this. But will it be that way?
For example, with this method I have my stock kernel backup, also make stock rom backup, install some custom ROMs/kernels and later just install stock rom and restore stock kernel using this method and I am back to starting point?
Hi, to return your phone to stock all you need to do is:
Make note of your current ROM and download the same from samfirmware
Download Odin
Perform full wipes and format system in recovery mode
Then into download mode where you flash the stock ROM in the PDA section of doing.
Included will be a stock kernel and root would have been lost.
To reset binary counter look at the app triangle away by chain fire.
All the best.

In case i have a Nandroid backup and i wish to restore it, how do i do it? I mean, i am aware that i will have to do it using CWM Recovery. I have my Nandroid backup on my external SD card. I wish to try some custom ROM's and would like to restore my Nandroid if i am not satisfied with the custom ROM experience.
Could you please list out the steps
Thanks a lot!!

To restore a back up:
Boot into recovery mode
In recovery mode enter back up and restored menu
Then select restore from external memory / sd card
Phone will restore to the time the back up was made.
Some kernels have different CWM menu layouts but the above should get you to the Nandroid backup you made.
All the best

Hello.
I've flashed the latest Siyah kernel (4.1.5) on my stock GingerBread 2.3.4, using Mobile Odin, not knowing that this version of the kernel is not compatible with Gingerbread, and ended up bricking my phone.
Now when i turn the phone on, I get the usual "Samsung Galaxy S II - GT-I9100" initial screen, then the eye logo of Siyah kernel, but after that the screen goes black and android does not boot.
I've tried Vol Down + Home + Power button combination a few times, even after removing the battery, but it looks like there's no way to even get into recovery mode, because the screen remains black. :crying:
Will I have to buy another phone, or is there any chance to save it?
Pleeeeease help me, I'm desperate!!
SOLVED
I finally maneged, I don't know how, to get into recovery mode, and I could flash back the stock firmware using Odin. PHEW!!!
My apologies for having opened this thread.
Recovery is both volume and power not home and power

In fact!
The post I read which was saying that it was that 3 keys combo must have been wrong...
btw... I'm so happy I could recover the mistake! I have also successfully re-routed my device with the old good doomlord exploit.
What I wanted to do was to install the latest stock ICS and have it rooted without triangle and counter issues, keeping a nandroid backup of my current rooted GB 2.3.4 in case I won't digest the well known ICS appetite for battery. I have rooted my phone using doomlord exploit, therefore currently I have no triangle and my counter is 0. Also, I've read that a full wipe of the phone is highly recommended before upgrading to ICS.
So my plan was:
To make a backup of all the apps, contacts, SMS'es, etc, using a few free apps available on the market, since I've read somewhere that, I don't know why, Titanium Backup can't be used in this case.
To install Siyah kernel in order to get CWM, with which I would have made a nandroid backup of the phone (but here I made the mistake of flashing the wrong kernel version).
To Download latest stock ICS ROM, and flash it using Mobile Odin, which would allow me to make a full wipe and inject the root permissions into ICS without triangle/conter issues.
To reinstall all the apps and reconfigure the phone using the backup made at point 1.
Do you think that the procedure should work, provided that I use Siyah kernel 2.6.14 (which is the latest compatible with GingerBread) at point 2?
Or perhaps it would be better to simply use Odin for PC, root ICS using CF-root, flash back ICS stock kernel (which would remove the triangle but leave the root permissions set), and then use triangle away to reset the counter? (but is triangle away actually capable of resetting counter, or all it does is removing the triangle?)
Since you are in Venice, I assume that you have the GT-I9100 or similar model. If so, you are in the wrong forum. This forum is for the AT&T SGH-I777 model, (US carrier) version. You should go to the I9100 forum to ask your question. And when you do, please post in Q&A, not the general forum. I asked a moderator to move this for you.

Flashing a stock ROM will not cause Yellow Triangle or increase your binary counter.
So you can follow below steps after you get all required backups using apps:
- Flash 4.0.3 stock ROM using PC Odin.
- Root using the method mentioned in http://forum.xda-developers.com/showthread.php?t=1501719 if you are concerned with Yellow Triangle and binary counter.
- Flash latest Siyah. Use Mobile Odin if you are concerned with Yellow Triangle.
- Flash any custom ICS or JB ROM.
Just follow first two points if you only need stock ICS with root. Factory reset is not mandatory but recommended so there are no issues later.

Thank you acekay. Now it's late but I will check the thread you linked. It looks promising!
Btw I think I must pay attention not to flash custom kernels or use CWM if I upgrade to stock 4.0.4, since I have the buggy eMMC and so would risk to brick the phone, wouldn't I? In such case I would try upgrading to 4.0.3, just to be safe.

If you flash custom kernel after upgrading to ICS 4.0.4, you are 100% safe!
the emmc bug itself is on the stock 4.0.4 kernel not the firmware as a whole

Ok. So the only thing to take care of is not to have both the stock kernel of 4.0.4 and CWM installed at the same time. All the rest is safe. Thank you for having made that clear.

2. then I'll install CM 10.1.
am I right?
I never read your 1st post properly,was thinking you didnt want to use a pc,and your on GB.
If your using a pc,you can flash siyah2.6.14 using odin which will give you root and CWM.
Youll need to see what the install instructions are for the rom you want in your other posr,whether you need ICS 1st or straight from GB.
Oh yeah I forgot to include that to my post. Yup. I don't want to use my pc. So, will it work?
Sent from my GT-I9100 using xda premium
What does the rom install instructions say;do you have to be on ICS or GB or what.
And I wouldnt recommend not using a pc.If you get a bootloop or cant boot,you can lose recovery/cwm and the only way out of that is using a pc.
Its best to get a pc setup so you can hook your phone up to it in case of emergency.
You can use mobile odin later if you dont want to use a pc(once your rooted) and/or cwm.

The only requirement for cm10.1 is to have cwm. And I say a post saying cm10.1 can be flashed directly to gb provided that it should have a cwm because cm don't need an ics bootloader.
Ps: my phone is not yet rooted.
And yeah, thanks a lot!

Believe it or not,Ive never seen anyone or anything saying that an s2 running GB can be rooted/get cwm without using a pc.
All the advice says to use a pc or update to ICS then use recovery.
Can you not access a pc for this and the reasons I mentioned earlier.And Im away to chuck out an xp laptop that works ok with Odin.
Hello,
during the last weeks I had so many problems with my S3 and now I want to send it in to Amazon so that they check it what the problem is, I'm still in my warranty time so I have all rights to do this.
So my question is I have rooted my phone so that I can use several programs better but I still have the stock rom. So is rooting is a violation of the warranty? Is it better to unroot the phone first? And if yes, how do I do this?
Anything else I have to check?
Thanks a lot for your help!
Basicly yes, it's better to delete everything before. However it depends on the method.
If you've used CF-AutoRoot then it should have such function, in SuperSU app called unrooting or cleaning. Then you just delete SuperSU (if it won't get deleted for whatever reason) and you're ready to go. If you've used CF-Root then you should flash original stock rom, kernel and recovery, with formatting of /system /data /preload and /cache. Or just using unrooting by SuperSU app and flashing original recovery.
However watch your flash counter, don't forget to set it to 0 before sending .
Depending on where you are from (I see Germany) rooting is not a violation of warranty (defined in EU law) and Samsung would have to proof that you rooting the phone did the damage whereas I would not bet on this.
Hence I would unroot, install stock rom, reset counter etc. as it is quite an easy process.
Good question, I really don't know how I rooted. The thing is I already did a factory reset last week. It looks like that my Phone now isn't rooted anymore. SuperSU was installed when I factory reseted the phone but now I tried to install Triangle Away to reset my counter, it said that my phone isn't rooted, same message appeared with Titantium Backup.
So I have to root it now so that the programs work and then I can unroot everything and reset everything? Or is it fine as it is? I just checked my Cutom Rom counter which is at 3. I guess these are my root attempts? Because I always used stock rom.

if your counter is 3, and to be very save, root, reset the counter, un-root following the guides here on XDA, doing the process now for 20min saves you time to argue with Amazon or whoever later on
Which root should I do now to use Triangle? CF-Autoroot oder CF-Root?
Thanks a lot for your help!

Does not really matter a alot, CF-Root will include a custom recovery (which will be overwirtten with stock rom flash if I am not wrong?), CF-Autoroot will not include it, hence I would go with autoroot
One last question, do I have to factory reset when I Autoroot with Odin? If possible I would like to keep my data at the moment and then I'd like to use Titanium Backup to backup at least some app savings. After that Odin and other can delete whatever they want.
Thanks again.
