I rooted my SGS2 a long time ago. Now i decided to sell it and buy a galaxy note. I got a great deal with one of my friends but he wanted it unrooted. I already flashed clockwork mod recovey on it and im scared that things might go wrong. Can anyone provide me some simple steps how to unroot sgs2........GT-I9100

I recommend to flash a stock/official ROM to your phone.
Then root will be lost.
You can download Official ROMs from SamMobile, but you will need to register before.
Or you can have a look into Intratech's Offical Firmware thread here => http://forum.xda-developers.com/showthread.php?t=1075278
Please read his first post carefully.
Then decide which ROM to flash.
As you want to bring it back to "normal", you should use a ROM from the second post "Official Firmwares".
Just flash the ROM using Odin - like described by Intratech.
Nothing special.
Maybe you want to wipe everything to go back to factory settings.
Then you should do a hard reset after flashing by dialing *2767*3855# into your phone's dial pad.
But you can alternatively do a factory reset in recovery mode - also after flashing the stock ROM.
Good luck !
Hey mate thanks for the reply, i backed up my original rom using rom manager flashed back to it....but i still have root and i want to remove it. Can i just flash the insecure kernel and using super one click do the job???/.....NOTE I HAVE clock work mod recovery flashed already........
Hello all! Long-time prowler, 1st time poster.
Finally got my hands on a GS2. Very pleased with it. I've always been interested in custom roms and kernels, as I've spent dozens of hours researching how-to's and don't-do's, but I've been hesitant to take the plunge due to the risk and 1st-time unfamiliarity.
That is, until now. I was following the rooting instructions here: http://forum.xda-developers.com/showthread.php?t=1311081
Specifically, point 2c using Entropy's root method (phone had the OTA UCKK6 update) to revert back to UCKH7 2.3.4. Everything went as expected, root was achieved (2.3.4, kernel 2.6.35.7, superuser, etc.), but wifi is DOA. It appears that everything else is working fine, but when I attempt to turn on wifi, it starts scanning for a few seconds and then shuts itself off.
I've searched both XDA and Google on the topic, and while it seems to be a common occurrence, there is very little information in the way of solutions. The closest I've come to has been this thread: http://forum.xda-developers.com/showthread.php?t=1364039&highlight=wifi+broke
Appears that a full un-root is necessary? I just wanted to double-check that there isn't some silly little thing I'm missing or a more streamlined solution.
Again, noob here. Any advice or input is greatly appreciated. Looking forward to trying out some roms and kernels and learning more from the community!
I've got the same problem ... kinda...I followed the same steps to root, WiFi was fine after that, but when I flashed CWM-recovery, WiFi was borked. This is where I usually shhot myself in the foot ( as I appear to have done again). After more reading and research, I found that the ROM I was planning to flash (UnNamed) did its own kernel update so I figured that it may patch my WiFi problem.
Sadly it did not and now I have NO radio at all. (Cellular, data or WiFi). I get FC's from com.android.phone. (over and over... every 5-7 seconds.)
Hmmmmmm...
Flash stock again just to make sure it got everything

That had crossed my mind, so I went through the root flashing process again, Odin3 gave it a "PASS," but the problem remains.
OK... Should I wipe before flashing stock? Thats the one thing that I didn't do. I wasn't sure which wipe to do so I didn't. (oops???)
Do a wipe data/factory reset now and you should have wi-fi again. I had the same problem and it worked after I did the wipe data/factory reset.
ehhhhh.... somethings up here. I did a wipe/factory reset, then flashed back to my virgin ROM with CWM-recovery on board. My cellular/ data is back but WiFi is still borked.

Or did you mean that I should have did the wipe on the UnNamed ROM?
Trying to do a CWM backup through the Rom Manager App so I can do a data wipe/reset (through the factory-reset option, or through CWM, just to clarify?), but every time I try to make a backup CWM gives me this:
E: Failed to verify whole-file signature.
Any idea what would cause this?

It is posted prominently in several places in the I777 forums, do not use ROM Manager app.
Starting with UCKK6, then flashing UCKH7 plus root package is known to bork wifi. A wipe data/factory reset will clear it if you wish to stay on UCKH7. Doing OTA update to UCKK6 without a wipe also reportedly clears the wifi problem, and will retain root.
To use ClockworkMod Recovery, you must first install a CWM enabled kernel.
ya...

Yuppers... ROM manager is incompatable with the SGSII. I just learned that yesterday. Its a P.I.T.A.
You gotta delete it then flash the CWM-R kernel to get the nandroid backup. Yes you are now backing up a modded kernel but otherwise you are pulling a raw (and virgin) FS image.
@SeniorGato
I can't interpret from your post. If you restored a previous backup from ClockworkMod Recovery, then you probably reintroduced the wifi problem.
Anyway, you want to be on UnNamed. You should do a wipe data/factory reset before you flash UnNamed. Then for good measure, it couldn't hurt to do another one after.

I did in fact go back to CWM.
From the recovery screen of UnNamed, I kernel flashed back to CWM, then did the factory wipe, then flashed the backup I made. The WiFi did work when I was on that ROM prior to flashing UnNamed. Now... not so much.
Anyway... Off to look for that stock kernel, then start over.
So do a wipe before each flash then?
Just finished re-installing the OTA update back to UCKK6. Root is still good and the wifi seems to be working. Thank you Creepy and Gato for being so helpful and gracious. There's a huge amount of information on here that I'm trying to sift through and thus a bit of a learning curve, but thanks for helping me through the first hurdles!
Yes, you must wipe before changing from one rom to another, ie stock UCKK6 to UCKH7, or UCKH7 to UnNamed, etc.
You can usually get by without a wipe when flashing the same ROM, ie UnNamed 2.0.0 to 2.0.1
Hmmmm...
So I've wiped, flashed UnNamed then re-wiped. Now I have no modem at all (again).
Looking in the about phone I see some interesting things...
model number: SPH-D710
Baseband: unknown
Kernel version:
2.6.35.7-sph-d710.el13-cl806482
build number: UnNamed v2.0.1
hardware version : unknown
And strange behavior (aside from the no modem thing): when the screen turns off, I have to restart the phone all over again.
I downloaded the ROM through the developement forum under the I-777 so I THINK its the right one, but this descrepancy in the model number has me concerned. Is it normal for custom ROMs to display incorrect data like this or have I completely hosed this?
This is totally *not* normal.
SPH-D710 is Epic 4G Touch.
The kernel belongs to the epic.
It looks like the phone won't even recognise the sprint modem.
I'm surprised your phone will even boot.
Your phone is the AT&T Samsung Galaxy S II I777, right?
If so, you need to re-download the UnNamed install file. The latest version number is 2.2.1 (not 2.0.1) from here. The file you want is update-unnamed-v2.2.1-full.zip.
I don't have enough experience to tell you how to proceed, but here is what I think will work.
If the kernel currently on your phone has ClockworkMod Recovery, and if you can boot into recovery, you might try flashing UnNamed from there. Do a wipe first.
Or, flash back to stock plus root, install a CWM kernel, and then flash UnNamed.
Edit: Yes, gtg released an UnNamed for Epic 4G Touch, which is currently on version 2.0.1. Somehow, you have downloaded and flashed the wrong package, but knowing gtg, it almost certainly does not contain bootloaders or param.lfs, so you should be able to recover. The kernel contains CWM recovery based on 5.0.2.7, the same version we have in Entropy's DD kernel, so you might try flashing the correct UnNamed directly from that recovery. Since you could go SGS II --> Epic 4G, you should be able to go back the other way. If that doesn't work, then flash the stock plus root using Odin or the Odin One-click package.
Well that does explain...
Weird part is that I DID use the I-777 forum's download. Anyway, I'm redownloading now.
*fingers Crossed*
So this begs the question, how are the sprint galaxy s2 roms looking, and how hard would it be to build a 'hellraising' package for them? If a straight flash managed to boot, kernel and all, might open even more possibilities for us.

Siyah Kernel 2.6.6 Troubleshooting
Hello again!
I thought I'd give flashing a kernel a go. I've been following Creepy's guide to installing a kernel via Mobile Odin (bought the pro version; easier and helps out the devs!). Got it installed on the phone and put the zImage for Siyah in the internal SD-card root and flashed from there.
It rebooted and showed that CWM had successfully installed, but the kernel is still the 2.6.35.14 as it was before. Not only that, but wifi is also non-functional again. Tried to flash it again; same result. Cleared the cache/dalvik and also ran the kernel cleaning script, then gave it another go. Still no Siyah kernel, still no wifi.
Great start to my XDA career, I know. Any help would be awesome!
If you're sure you have root and can boot to CWMrecovery, you may try mounting the phones internal USB memory (not the removeable SD card) on your computer, move the entire zip into it and flash thru CWM recovery. Once I had the right ROM *sheepish grin* it worked immediately and perfectly. My wifi is back and everything!
A thousand thanks for all the help!
Edit: I just reread your post. First check what recovery you are booting to. 3e or CWM?

Hello,
I recently put a custom ROM on my Galaxy Player. But I want to put a new ROM on my Player. Do I have to remove my current ROM? Or just flash the new ROM with odin, without removing the old one.
I've been searching on google, but I didn't find any clear answers.
Can someone please tell me this?
Thanks
Nevermind I got this. I just installed the new ROM onto it, without removing the old one. Hope that the right thing..
Yes, but usually you want to do a factory reset deal with it, before and after flashing to new ROM. If you have a Nandroid backup, all you have to do is an advance restore and restore your previous data without all of the hassle.

Factory reset prior to flashing a rom would be enough in my experience... but I guess after wouldn't hurt either... your preference and time...
quick question about flashing these players can we put the roms straight to sd card and flash thru cwr or must we always flash thru odin?
what ROM are you using successfully?
what RoM did you use? Do all hardware features work? (wifi, camera, etc)
Do you have the Player 4 or 5? US Version?
I have the 5" US version and want a newer version of android than the one that came with it. When will 4.0 be available in a custom ROM? Any ideas?
klins rom with u.s. steve kernel 4.0 u.s
I think he was asking when an ICS port was gonna be available.
So far people are having a hard enough time getting CM7 or CM9 to port to our devices. So if ICS does make it to us, it's still a ways out.
so does anyone know if we flash just thru odin or can we flash thru cwr as well?
How do you get clockworkmod recovery?

You can just flash Entropy's kernel with odin and it'll give you cwm. After you flash just turn it off and hold the volume up + power until it says Samsung, then you let go of the power button and that's it.
Hi guys.
First up hello. Im a refuge from the Ace section, have a Galaxy SII due for delivery over the next couple of days so Im moving over. On the Ace I flitted between CM7, CM10 unofficial, Lewa and a few others.
Im generally used to rooting via stock recovery and then using CWM to do everthing else, not familiar at all with ODIN as I have never needed to use it. Standard UK SII, unlocked running Gingerbread.
Have read around this section and will continue to do so for a few days, but a few starting pointers would be nice.
Rooting/CWM/Kernels
Whats the easiest way for rooting the SII, preferably from stock recovery
Whats the easiest way for installing CWM?
What the best basic Kernel out there, or Kernel that will do an AIO Root/CWM/Kernel job?
Im reading a lot about this hardbrick lark with ICS, is this purely an issue with stock ICS roms, and its fine to go down the CM10 route?
I can use the search feature, but as Im sure you know thats not always the most productive route.. Although I shall use it in the meantime.
Cheers.
You can learn a lot just by reading peoples problems, and the answers given.
For rooting, you would normally just flash like a siyahv4+ kernel with Odin.
That gives you root, cwm and safe from brickbug.
Theres several other ways also like exynos or doing stuff via recovery.

How have i avoided ODIN so long.. hmm, Siyah 4.
Do you know how cumbersome the search feature is here, finally found the download for v4.1.15 (and then realised it was in your signature), now im trying to find the instruction to install via ODIN,. If you happen to know offhand, the exact thread that would be appreciated.
Regarding roms, Im assuming CM10 is the standard, not familiar with any of the devs over on this side of the fence.
Ok, from what I can gather
Download Keis and make sure all drivers for the SII installed
Download Siyah-s2-v4.1.5
Disconnect your phone from your computer
Start ODIN
Click the PDA button, and select Siyah-s2-v4.1.5
Put phone in download mode
Connect the phone to computer
Make sure repartition is not checked
Click the start button
Wait for the phone to reboot
correct???
(sorry, i suffer anxiety, one of the side effects is double checking anything before doing it)
If your on ICS, you can download that siyah kernel, but make sure you get the .zip type.
Get the 1st and 3rd file in the ics rooting guide in my sig.
Stick them all on sd card.
Boot into recovery.
Flash the 1st file-which is temp cwm
Flash the 3rd file-which is su/busybox
Then flash the siyah file-which gives you permanent cwm and safe kernel.
Then reboot phone.
Then you are rooted, with cwm and safe kernel.
The easier way is obviously using odin.
Ps.hope you aint got the g model.

No, its not the G..
It is on gingerbread currently though, not ICS.
GB ffs......lol.
Right you can update to ICS (pain)
or
Set up Odin and flash siyah s2 v2.6.14.tar file
or
Try exynos abuse (may not work on GB).

I shall go S2 v2 route then. assumedly i can then just flash cm10 iwthout any problems.
Yes GB model, but no, not GT-I9100G
Youll need to check what the install instructions are for the rom
Eg if you need to be on GB or ICS.
Ive never used it, Ive just read you need cwm though.
If possible I would first update to ICS via Kies or OTA then afterwards flash Siyah v4 via ODIN. Once you have done this you are ready to reboot into cwm and flash away. Remember to wipe data/factory reset in CWM though after flashing Siyah kernel and before flashing new rom.

Ah, ive been reading on problems with ics and hardbrick, i guess that is prevented by flashing siyah post update.
Thanks guys, sorry for the noob questions, im not a noob, but rooting always makes me nervous (a hangover from the days when flashing the bios on the pc was a dangerous hit and miss affair), i just like to double check.
Once im rooted and got CWM im back in familiar territory.
Any other general tips on making the leap from Ace to SII appreciated.
Dont you just love it, when the phone arrives and its pre rooted with siyah and cwm
UPDATE: It all worked fine!
First of all, I am sorry if this question has already been answered. Yes, I have searched for it and found some answers but this is just to make sure everything's alright.
Anyway, since I bought a new phone this X-mas I have put my Galaxy S2 in a locker and, although I am not a newbie in this scene, I just wanted to make sure I don't mess up the whole procedure. It is just that I have never had to go back to stock.
So, what I need to do is make the phone run 100% Stock (Official 4.1.2 JB) again because I am planning to sell it next week.
Currently the phone is rooted, has CWM recovery installed and is running a custom AOSP 4.1.2 ROM with Dorimanx V7.27 kernel.
Is it true, to go back to stock I'd have to do the following:
1. Wipe data/factory reset, Wipe Cache Partition
2. Flash the stock .tar image file using Odin
Did I miss anything?
UPDATE: It all worked fine!
Sounds good to me
