i am from galaxy mini forum so get a galaxy s2 but how to know if it is S2 or S2 GT-i9100 o and what the diffirence?? and can you gays pleas link me to a tut aboug instaling costome recovery, which ODIN to use and so on .... last thing which is the best stable rom to use .....thanks in advance
1) Check the sticker on the phone chassis under the battery.
2) Differences between SGS2 variants ? Wikipedia.
3) Just about everything you need to know to get you started is in the Stickies.
4) There's no such thing as the "best stable rom to use". There are a heap of custom roms for the SGS2, it's an individual preference thing. And because no two people use their phone the same way or have it setup the same, and because component-wise no two phones come out of the factory exactly the same, your experience with a particular rom will most likely vary from mine.
The best thing to do is to get your phone rooted, preferably with CWM installed. This will enable you to backup, restore & flash roms/kernels in a matter of minutes. You can than try a bunch of roms for yourself. If you find you don't like a rom you try, it's easy to go back to your previous setup easily by restoring a backup; recommended regularly/before you flash anything to your phone.
ok so by flashing cwm and then a costom rom the divise will root by it self and do i have to flash a stock ics rom to install a costom ics rom??????
Lackchoo,
Flash one of Chainfire's kernels. His instructions are very clear. That will give you root and CWM, and possibly also a yellow triangle at startup which you shouldn't worry about at all.
You don't need to flash a stock ICS ROM to flash a custom ROM. After rooted, in CWM, just install the downloaded ZIP ROM file of the custom ROM. You will keep root and triangle will go away.
Ditto what the above person said about ROM's. However, you can try Cyanogen (Do a 'stable' release, not a 'nightly'), its the most 'popular' ROM in terms of numbers. One can't and shouldn't say which one is best. But for a newbie, I think Cyanogen is a good place to start. Perhaps it will give you the least issues and the most 'oohs!' for your initial newbie effort
I don't have the links with me from the smart phone, but just search 'chainfire kernel root galaxy s2' and 'cyanogen galaxy s2' and you should find the relevant thread. Read it slowly and repeatedly! I know I had to

I have a rooted w/cwm recovery stock 4.04 on my galaxy s2 sph-d710 and I wanted to get the 4.1 cm10 rom on my phone, but I am not sure exactly how to go about it because what I find tells me to first install the GB based cm9 but im worried about going backwards from ics based to gb based roms, as well as potentially getting the factory reset bug. anyone know how I should go about this? thanks

I like people who ask questions before messing around with their device but This is not the right place for you because Your are using Sprint's variant of galaxy SII from your phone details.
You can check your forum here:
forum.xda-developers.com/forumdisplay.php?f=1281
-You don't need to flash Cm7 (gingerbread) but you might have to first install CM9 (ICS) as base in order to have seamless experience after flashing CM10.
***PLEASE READ THIS IMPORTANT INFORMATION***
- Please do not wipe/factory reset your phone Since you are running stock 4.0.4 ROM on a stock kernel.
-please search for a safe custom kernel in your own section, flash the custom kernel first, before trying to factory reset our wipe your phone.
-You can also open a thread there and ask for help before proceeding to CM10.
-FAILURE to adhere to my advise might lead you to bricking your device. It's better to be safe than sorry!

Swyped from my Samsung Galaxy SII
Dear all,
I know there are multiple threads running for the same, but still i was not able to understand most of the way. Am having SII which is running on Android 4.0.4, I want to root my phone so that i can install Jelly Bean Rom available in the forum.
last i have rooted Galaxy Spica 5700, but it required flashing device with Odin and instillation of a new kernel. But it seems like many new things have came up. Can someone please post me Point by point procedure of rooting my device with ClockworkMod recovery.
Plenty of threads that answer this question in detail. No need for people to duplicate topics or answers.

If you know how to flash kernels via odin its simple. Just download siyah kernel for i9100 , install the drivers required fr odin , flash the kernel in download mode. It will give you rot access and CWM recovery. Then yo can boot into recovery,wipe data/cache and install any rom you want. But do not wipe anything n stock recovery since you are on 4.0.4 (which has the brick bug)
you can also root by stock recovery just by flashing a single .zip file. But if you know the way to do it by odin i suggest the odin mehtod.
and to flash JB....MobileOdin Pro.......so you'll forget about rooting with the EverRoot option........................beware of the wipes with 4.0.4 tho, that crap is nasty.
Hello, Been A while since i logged in at XDA, ~ i have a few Noobish questions that are quite troublesome to find, ~ i did look at the forums, google and other sites, i have some answers but not generally what i was looking for, so might as well ask the Experts and maybe get some easier tips hehehe, :fingers-crossed:
I have a Sony Ericsson Xperia Play and since then im ok with it, but now i got a good deal for a Samsung Galaxy S3 Gt-i9300 (i was thinking of a getting the S5 but still waiting for every quirks to settle down) , so a stepping stone in the Samsung Direction, :laugh
Specs:
Samsung Galaxy S3 GT-i9300
Android ver. 4.0.4
its from United Arab Emirates
Status: i Rooted the Phone Using Sir Chainfires thread here ( For Root ) then i installed a CWM here ( For CWM ) ~
Questions:
1.) Is there a more simple way to Rooting and Installing a CWM?? (tips too)
2.) This phone has an Unlocked Bootloader, is it Possible to Lock it by FLashing a Stock ROM??
( i don't want to Lock it, i just want to know, cause some posts declare that their bootloaders got Locked when Flashing a Stock Rom)
Installing a Custom Rom for Xperia Play is usually Posted by the Creators of the Rom,set of Instructions on what Ver. of android you have to be on, and what Kernel your Suppose to be Using, so,
3.) Here in the Dev. Section, i don't see threads for Instructions for that, (it's kinda confusing for newbies) do I have to be on 4.2 to use a 4.2 Custom rom??
4.) Does the S3 have Custom Kernels?? should i Use custom kernels for S3??
5.) Differences of this SECTIONS??

I've red on some Threads that you Can't Revert Back to ICS if your on Kitkat (OFFICIAL ROM)
6.) can i Revert to ICS even though i upgraded to Kitkat or Jellybean?? (just downgrade to any Firmware i want)
Some Posts and Videos i saw have used Phone and CSC on their ODin
7.) What are those exactly (in layman's term) ?? and can someone link me to a nice guide of Odin (got a few but a bit complicated for me )
Some Threads say that i have to be in a certain Version of CWM for me to use it on a higher Ver. of Android
8.) how to tell what those Ver. of CWM for Certain Ver. of Android??
9.) is the method for Rooting ICS , JB and KitKat Different??
10.) Can my Old Titanium Backups work with Newer/Higher Ver. of android or ver. of Titanium Backup
that's it, any help and answers to this questions will be of Great Help, and links to would be Epic, THanks in ADvance, :victory:
Read all the sticky threads in general forum, all the important answers are there.

1) Try framaroot or cf auto root. Cwm just install zip and flash it after u root ur phone.
2) No, flashing roms will not lock ur bootloader. All instructions on how to flash the rom will be on their respective thread.
3) No, u do not need to be on the same android version to flash the rom.
4) Yes there are custom kernels for the s3 and its all on wat u wan.
5) Original is where the devs create the mod or rom and the one without original is the one where devs get the rom base from the original forum and edit it.
6) Once u are on 4.3, i advise u not to go back to previous android versions unless u know how to backup and restore efs. And 4.3 is btr than previous versions anyway.
7) There is a sticky the forum. Just update ur recovery to the newest and u will have no problems.
8) There is no versions of cwm limited to certain versions of android.
9) No, as i said, just try framaroot or use cf auto root.
10) Yes they will.

First things first.
The efs is the most important, irreplaceable part of your phone that holds device specific information, with imei, sn, etc. It has 2 versions:
Efsv1 is present in all ics 4.0 firmwares and jb firmwares before 4.1.2 with baseband mg4.
Efsv2 is in all firmwares starting from jb 4.1.2 wirh baseband mg4.
Efsv1 can be converted to efsv2 by flashing. Efsv2 CANNOT be reverted to efsv1 unless you have a efsv1 backup.
So, first thing, use framaroot to root your ics firmware and make a backup of efsv1 using the ktool app (free on playstore). This is very important because if you update to efsv2 firmwares and ever want to downgrade to a efsv1 firmware you'll need that backup to keep the phone working. So keep that backup and copies of it stored in case you ever need it.
Also efsv1 can be network unlocked using galaxy sim unlock, free version in the app section, paid version in the playstore. But efsv2 cannot be unlocked through free hommade methods.

Hi to all...

CyanogenMod version 11-20140804-snapshot-M9-i9100
Kernel version 3.0.64-CM-g89e6992 build03

or any other custom or stock rom.
after all, i need to rooting the device to be more flexible
can anyone give me some help ??? rookie here...
thanks in advance
The device is already rooted, you just need to download any custom ROM you want, reboot to recovery, and flash your desired ROM from there.

first of all thanks for your answer.
If I understand properly
therefore, I'll have not any problem because of 4.4.4
that is correct ?
Yes, that is correct. The device is already rooted, with custom recovery, which means you can just reboot to recovery, wipe everything, and flash any desired ROM you want.
@@[email protected]........No disrespect intended, but this is "flashing 101" basics stuff........
The fact that you are asking it, tells me that you don't have the experience needed to do this comfortably.....
That's not a problem though.....we all start from the bottom, and learn as we go.....
But that being the case, i'd advise that you don't do anything to your phone until you've read, learnt and completely understood the processes behind the flashing procedure. It's best to understand what you are doing beforehand, rather than trying to figure out what went wrong afterwards.......
