Hi
I have not modifyed my S2 anything since I bought it, only updated via Kies.
I have read som rooting threads, but it seems to be more than 1 way to do things.
I wish to flash a custom kernel (Cognition S2, VillainROM or TK-rom)
But before I can flash a rom I need ClockworkMod Recovery.
Which methode should I use? CF-Root v4.0 or ClockworkMod Recovery 4.0.0.5
The first methode also brings root, but is this nessesary since the custom roms I wish to flash already are rooted?
Also does anyone know if Heimdal works for S2?
Thanks!!
bump
always wanted to know that too
seems to confusing to me
i did search for it and its just too confusing
from what i understand is that
( do this then this and dont forget that but before u do this do this and dont forget to do that before u start anything and when u finish that do this restart hold three buttons then do that wait for the yellow thing press next wait for it then do that and ur finished but if a triangle appears or you brick your phone u need a 301k resistor or buy a jig and then start steps RI8 to bmx23 and then your done)
sometimes i hate android
the problem is nothing is found in one thread
FAQs are scattered everywhere with not a lot of information
i wish if there was a post that has everything i need to know ive been here for a while and im still learning new stuff
i hope some one answers this for you
You can just flash the CF root kernel and download from here http://forum.xda-developers.com/showthread.php?t=1103399
Pick the kernel that correlates to the firmware you are using.
Once you flash that, you can get into recovery by holding Power, Volume Up and Home button when the phone is in an off state. Then you will be in Clockwork Mod Recovery and can flash new roms.
Its really quite easy once you get the hang of it and ODIN is quite useful as you can flash just kernels or modems using it or quickly go back to a stock ROM.
Yes this method brings root but its just an added bonus in case you want to back everything up with Titanium Backup before going into CWM to flash a new rom. Root isn't necessary but it doesnt matter if it roots before you install another rooted rom. The new ROM will normally wipe everything anyway if its a wipe rom.
Heimdel does work but I don't personally use it or know which is the newest and best version to use with SGS2
Oh and this thread was created for beginners of SGS2, it is attempting to put all information in one place to try and help make it easier to understand http://forum.xda-developers.com/showthread.php?t=1125282

Hello XDA,
Let me start by first saying that I am pretty much a complete noob to all of this. So I apologize in advance for insulting any of you with my stupidity when it comes to the subject.. Anyway, here we go...
I have had my SGS2 for a while but finally worked up enough courage to flash after reading all the positive reviews about it. I followed this guide http://forum.xda-developers.com/showthread.php?p=18576627#post18576627 and used methods 2c and 3a.
I was able to preform the root with absolutely no problems. Everything was great. I had a little trouble finding a kernel for 3a, but ended up trying out Siyahs (http://forum.xda-developers.com/showthread.php?t=1367800). After installing the Kernel everything was still working great. The last thing I wanted to try was a new ROM. The ROM i wanted to try was the Cyanogen mod (http://forum.cyanogenmod.com/forum/494-samsung-galaxy-s-ii-att-experimental-mod/)
When I used CWM to install the mod the phone restarted and came back on showing the SGS2 boot screen... only to stay on the SGS2 boot screen. Nothing happens. The phone just stays on showin the boot screen. I've let it stay like this for 20 minutes now and nothing is happening.... did I break the phone? Whats the problem...
I've never flashed or used cyanogem mod. Did you flash CM7 or CM9? With CM7, I've read lots of posts where they say you have to flash twice. So I'd try flashing it again. Tell us exactly what you flashed. Maybe someone who knows that rom can pitch in with help.
You didnt flash the rom or recovery from ROM Manager did you??
Sounds like your in the same boat mine was in up until this afternoon.
Get Odin and try to use the one click installers to return to root and start over with the proper directions.. (You can find all the software you need in creepycrawlers Download Repository link in his sig)

Thanks for the quick responses guys. What I did was turn the phone off, and hold volume up+down to get into CWM. I then restored my backup I had made right before trying to install cyanogen mod and luckily everything works normally. Phone looks good and smooth. I have to say though I am really nervous to try and flash another rom. I want something nice for my i777 but can't find anything. Does anyone have a suggestion for a decent rom?

You might want to try Batista Foxhound http://forum.xda-developers.com/showthread.php?t=1486199&highlight=foxhound. Like me, I'm very particular about the sound of the media player. If you want the best sound, flash CM7 RC1. Install power amp and play with the CM7 DSP manager and power amp equalizer and there is not a single ROM out there that can match the sound quality of this two combination. Good luck.
Hey, im new here, and completely new to the whole "custom rom flashing" thing.
I would like to get into rooting my phone and then installing a custom rom like resurrection for example, but I have a couple of questions.
1. Do I need an SD card in my phone, to be able to root my phone/install custom roms? or can I just use the phones internal 16gb memory?
2. Would someone be kind enough to point me to a guide to rooting/installing custom roms for complete newbies like myself? I have searched the forums, but theres so many threads about different stuff, like clockworkmod/odin/cyanogenmod etc, my head is completely boggled. I just don't know where to begin with any of it.
Cheers.
1) No.
2) Everything you need to know is in the Stickies.

1. No you cant root without an SD card? or No you don't need an SD card? elaborate please.
2. Nothing in that thread helps someone like me who is totally new. I don't know what any of it means. Surely there is a simple guide that explains exactly how to root your phone, without linking you to 7 other threads in the process? That's all I've found up until now.
This requires sdcard

Thanks, thats what I was looking for.
One more thing, just so I dont make a mistake, could you tell me which kernel to download? my kernel version is 3.0.15-I9100BVLPB-CL310231
cheers.
Read the bit in bold read which says 'Help ! Which file do I use ?'. This short section answers your question exactly.
ok well i tried CF-Root-SGS2_XX_OXX_LPB-v5.2-CWM5-PROPER.zip and my phone no longer boots....
tried CF-Root-SGS2_XX_OXX_LPB-v5.2-CWM5.zip and I get the same thing, so im stuck now. great.
I can get into CWM recovery, but I have no idea how to copy the rom I want to use onto the phone when its in recovery mode. This is something that is just not explained anywhere
help?
Right. In order of importance:-
1) No bumping threads within 37 minutes. Not cool. This is not your personal tech support forum.
2) You're having problems. Why ? Who knows. We're not there looking over your shoulder so we have no idea exactly what you did. I suspect you're having problems because you are in too much of a hurry/took shortcuts & didn't do what was suggested immediately after your OP.
3) However...Given the situation you find yourself in, I recommend you do one of two things:-
A) If you are absolutely sure you have CWM Recovery & not Android recovery (I say this because if your phone isn't booting normally, that normally means the flash didn't work & normally CWM wouldn't be successfully installed either), follow whatever instructions the rom you're wanting to flash has.
Every single rom on here has flashing instructions, normally on the first post on the first page of the thread on here devoted to the rom. If you can't be bothered reading those, I can't help you.
or
B) Go to Samfirmware.com. Search for the firmware that was on your phone before you tried to root it. Download this firmware. Flash the firmware you download following the instructions here. If you also end up with a .dll file, bin it. You don't need it. This will give you a clean install of stock. From there, I strongly suggest you read the CFRoot thread very carefully before you attempt to root your phone again. I also strongly recommend you read the Stickies linked to above, so you have some sort of understanding around what's what with this phone.
If you don't, being a betting man, I'll wager there's a fair chance you'll find yourself in the situation you currently find yourself in again (best case scenario), or worst case you'll end up with a 135gm paperweight as many people have on here over the past few days.
It's all up to you now. Your phone's destiny is in your hands.
Thanks for the reply, much appreciated.
Sorry for bumping, I panicked a little when my phone wouldnt boot. I just expected it to work because I have done things like this in the past and never had problems. Im a pretty tech savvy person really, im just new to android.
I wish it was as simple as reading one thread, but there are dozens of different threads on how to root this phone, and different methods, its extremely confusing.
Im downloading the stock kernel now (300+mb for some reason, and its going to take over an hour to download)
Once I get my phone back to normal, I'll read through some more threads and try and get a better understanding on how to root my phone.
I had it rooted properly as the recovery mode stated CWM in the corner, I think the issue I had was not being able to copy the rom I wanted to use, onto the phone, because I dont have an SD card.
Anyway, thanks for the help, and fingers crossed I can at least get my phone to boot again.
Man, I've never come across anything so complicated in all my life lol.
Edit: Sorted! Flashed back to original kernel and its working as it was before I started. Thanks very much for your help mate, and at least now I know how to restore my phone if I mess it up again in the future.
just thought I would update this thread and say I finally accomplished what I wanted.
Incase anyone is wondering, this is what I did:
Restored my phone back to factory settings/firmware/kernel
Booted the phone up, and copied my rom of choice to the internal memory via USB connection, and enabled debug mode.
restarted in download mode and flashed cf-root kernel (ended up with bootloop)
went ahead and installed the rom via clockwork recovery (creating a backup first)
The phone now boots into the rom im using (Resurrection Remix)
So if anyone is a little worried by getting the bootloop (but can still get into clockwork recovery) try flashing your required rom. Your phone may boot fine with new rom anyway. Mine did.
I've been having this weird problem recently.
I originally was running an AOKP JB rom for a bit, working fine with CWM recovery. I decided to go back to a rooted touchwiz with CWM. I booted up odin and flashed the SU update from rootgalaxynote.com, nothing happened. Tried again, Nothing happened. I apparently have superuser access, but no Superuser app.
So I grabbed a CWM from here and threw it through ODIN, flashed it, I held down VOL UP and VOL DOWN while it was booting, boila, CWM boots up and my flash my SU.zip.
Boot up, everything is kosher and I have root, but the problem is, every time I try to boot up recovery NOW, I get the damn 3e one that does hardly anything.
any advice on what to do? I don't like flying with no landing gear.
The stock TW rom included a script that auto installed the 3e recovery when a boot sector modification is made.
It's an annoying little perk that Sammy added into the framework.
The fix involves a boot at the proper time during the root process.
I believe the steps can be found in the super thread under the ICS root instruction threads.
Easy fix ..really annoying safety mechanism ....g

I stopped buying HTC phones because of their s-on and locked bootloader policy. Samsung is by far easier to modify. Its also very hard to brick (your recovery automatically reinstalling is an example)
Anyway, for your issue, after you get the green box from Odin, you do a battery pull to interrupt that script.
Thanks ranger ...
I remembered the script, but not the process ....
Old guy here ...LOL
Thank you Sir ...g

My last device was the inspire 4g...and if not for the famous "random reboot" issue, I'd still be using it...
They even have android 4.2 for it ......sigh
However ...the note 1 is impressive, and I have enjoyed this device more than the past 10 combined.
Thank you in return ....g
wish i could remember the exact process but i recall the i717M had a similar issue but it was resolved by pushing a different tar or image file onto it.
I recall stumbling on it either here; http://rootgalaxynote.com/
or in xda's i717m areas. good luck.
Be careful with that site. Many have come here after they flashed GB kernel onto ICS and vice-versa.
Make sure you read carefully.
The script only affects Canadian phones that were updated OTA. Here is the link to tell you how to get around the script.

Hello first time rooting this phone. Its a SGH-I777. I used the guide from galaxys2root.com/. At first it didnt work because my computer didnt recongnize my phone. I tried a different computer and it seemed successful until it rebooted. When the phone rebooted it did nothing but stay on the first screen. I still have the ability to get into Odin mode(download mode), but that is it. When i put the phone in download mode and use Odin it allows me to download the "zimage" but after rebooting it is the same exact thing. I have tried the one click root, one click factory restore. Tried restoring it on Kies. and nothing work took it to a store and the guy said he tried but it would stop in the middle of the download the only option i had with him was purchasing a new mother board for $80. Does anyone have a solution that can help me fix my phone.
Before i attempted to root it, it had OS 2.3.6 with kernal 2.6.35.7.
Go to the development section and read the stickies. There you will find stock rooted packages you can flash with Odin.

@jmula,
Enter recovery and perform a wipe data/factory reset. That may clear the failure to boot. If not you'll need to flash back to stock and start over.
The yellow trangle is a result of flashing a custom kernel using Odin or Heimdall, and is expected. You are not the first person having problems with the tools provided by GalaxyS2Root. In the future, I would recommend you avoid his site.
And... as suggested, read and study till you understand the basics. Then if you have questions, feel free to ask.

You should be able to enter recovery. Hold down all three buttons, vol+ vol- and pwr, continuously until the phone boots into recovery. It could take 10 or 15 seconds or more. If that is unsuccessful, then since you can enter download mode, you will need to flash back to stock, or stock plus root. That is not just a kernel, but the entire package. Please see the links in my sig for instructions.
The dropbox links in the download repository are temporarily suspended until probably Monday night or Tuesday as someone abused and over-downloaded. But the hotfile links still work.

The next thing I would suggest is to try and flash the UCKH7 full stock package with bootloaders. However, as the dropbox links in the download repository are currently suspended, you will have to download it from SamFirmware. To be able to download, you will need to register for free if you havn't already. Search sgh-i777 in the upper right hand corner of the page, then download the I777UCKH7 version. Let us know if that will flash.
Ok it finally wokred after countless times of changing usb ports. I used the one click recovery. It restroed my phone to 2.3.4 i had 2.3.6. I tried to update by kies to 4.01 and it didnt work. Kies froze. The queestion is how do i safltey root the phone?

Flash a .tar version of a custom kernel with Odin. I always use an old siyah.tar, but that's just me. There are other methods floating around but that's the quickest and easiest for me. I think there's an old entropy dd.tar around somewhere too. But just flash it through Odin and you're good to go, assuming you flashed one for your version of android. If you just want to get into recovery to flash something this works as well.
There may be links to tar versions of the kernels in creepy's sig I don't remember offhand.
Ok since i do not want to brick my phone again where it is just stuck at the boot loop. I tried looking for ways to root and when i tried some of them my phone went back to the problem it had it the beginning. Should i just call it quits or do you guys have a guide?

Give up???
I personally don't think flashing a kernel with odin is the best way to root. It increments the flash counter, for one thing, though I'm not sure how many people care about that anymore. I would suggest that you use the stock plus root package to root the phone with odin. See the links in my sig.
Guide... did someone say guide?

First, to Creepy....you've been a great resource here and I read a lot of what you post and you got me out of the very jam being discussed here. I made the mistake of trying to root via the galaxys2root.com site (actually, I thought it was a different site...was redirected), got the i9100 screen and a boot loop...couldn't go anywhere. I came back here and found resources eventually unrooting my phone all the way back to 2.3.4, then moved to 2.3.6, then the stock android 4.0.3 which updated to 4.0.4.
But I still want to root (4.0.4 shuts itself down A LOT...more than 4.0.3) and I have a Galaxy note 10.1 with JB 4.1.2 and I LOVE IT! I feel on a mission to get rooted and try out some of the JB roms I see talked about here, but can't seem to find the best way to root. I've heard exynosabuse referenced here (no links to it though) and I don't want to use the wrong one and mess up my phone. I've been reading for weeks here and there's obviously a lot of great material, but I'm not sure which material is critical to understand, and which is "nice to know" but might not even apply, and which material isn't even right. Very frustrating.

The ExynosAbuse application is the only practical way to root 4.0.4 without changing base. You can download it as an attachment in the OP of the developer's thread, but read through the thread first to understand its limitations and risks.
Alternatively, you could flash 4.0.3 plus root from the development forum. If you choose that route, please read the thread to understand how to install a custom kernel, which is recommended whether you plan to install a custom firmware or not. The custom kernel will contain ClockworkMod Recovery so you can flash the firmware of your choice if you wish.
There are really several routes you could choose. All of them work. Another would be to flash back to stock Gingerbread plus root. For that see my guide How to Flash Custom Binaries Without Ever Incrementing the Flash counter!! (link in sig)
Hmmmmm..
Well, I see that their are many, more experienced than me following this thread and my following comment is not meant to jump on the knowledge train here, but............... I had the same event happen as the orig poster earlier today. I had installed an app,I then rebooted and it got a bit stuck on the Galaxy SII, What I did was go into recovery ,cleared the Dalvik cache and that is all I cleared. Then I re-installed the RR Rom .rar, which I keep on my SD, over everything and rebooted, it came back as it was 4 mins before . All I did after, was do a system restore(only) using Titanium BU. So when I see all the "clear and restore this and that" I started to doubt some of the more experienced than I. My 2 cents is, that, if one does not know EXACTLY ,how to correct an issue,leave it for our more knowledgeable brothers and sisters.
If I am wrong ,please except my appology.

I don't know what you're trying to get across here. Yes, restoring a backup nandroid works. Yes, you can try wiping cache and dalvik to see if it fixes an issue. Yes you can restore apps via titanium backup. All these things are indeed true.

And yet you say, "All I did after, was do a system restore(only) using Titanium BU." This may have worked for you, but this is an absolute recipe for disaster, and should not be given as a recommendation.
And further, from what you say, you did not have the "same event happen as the orig poster." Instead you "had installed an app,I then rebooted and it got a bit stuck on the Galaxy SII." This is by far not the same as trying to root with a tool from GalaxyS2Root.
