I have root my SGS2 and I put on it ICS Rom. Now I can go in clockwork mode with Rom Manager but not with the bootons options when the phone is off. Can someone help me please?!
What happens when you do it?
flash another kernel/rom
Root but does that mean you also installed CWM ??????

It seems you have flashed a rootless ICS version - flash a corresponding CF-Root kernel for your build and you will have CWM available from cold boot.

hello friends
I am not able to install any ROM on my S2. I tried to download miui rom but after downloading when i try to install through ROM manager premium it is rebooting in recovery mode and not able to verify signature. i updated S2 with XXKG6 kernel recently. before that i has KG3. I n any case i am not able to put any ROM.
Anyone can give any resolution?
You need one of these kernels http://forum.xda-developers.com/showthread.php?t=1103399 then you can boot into recovery and flash the zip.
Hi all,
I rooted my SGS2 (KE7) with CF-Root ages ago and haven't done much since then, aside from take regular backups.
Looking at the Cyanogenmod stuff, I fancy giving it a go. All the guides talk about using the kernel at http://forum.xda-developers.com/showthread.php?t=1118693 .
Does anyone know if I can flash the cyanogenmod ROM using the recovery mode I have with CF-Root, or if I need to get use the kernel from the above patch first?
This morning I tried installing the kernel (from the CF-Root CWM), when my phone rebooted, the touchscreen worked on the unlock page but not once I unlocked (I use LauncherPro as my launcher). Rebooting into recovery mode didn't work (the phone just booted normally) so I reflashed CF-Root but still had the same problem however I could boot into recovery mode and restore this morning's backup.
Now, the phone boots (with the warning triangle, expected) but there is no response after I unlock for a minute or so. Setting the stock launcher back works but I'm confused about why this should happen and what I should do next.
Does anyone know why my non-stock launcher is now being non-responsive for the first minute after boot / what I can do to get it back?
Am I able to install cyanogen with CF-root, or do I need to use the kernel in the above link? and if so, do I need to do anything other than just flash and if not why didn't the phone boot into recovery when I tried it earlier?
Any suggestions gratefully received!

The cf-root kernel is all you need to install cm7.

This is correct. However, after you install the cm7 .zip the first time, it will have only installed the kernel for cyanogen mod. So you will then need to boot back into recovery with 3 button mode and run the zip install again from there. You will then have CM7.

Don't quite understand this. I've got the cm_galaxys2_full-39.zip (100MB), I was going to put this on the SD card, boot into recovery mode and install from there. Are you saying I need to do this same process twice? (and if so, why does it only install the kernel the first time when it is the complete zip file?)

CF-root => Cyanogen mod
Hello everybody,
There are a few threads that discuss this question, but they all draw a different conclusion.
This one for instance : http://forum.xda-developers.com/showthread.php?t=1367933 (or if the link is broken, search for : How can i use cf-root kernel for cm7?).
In the thread above they claim that CF-root is not compatible with CM7, however in this very thread there is said that when installing the .zip file twice, it should work just fine. As i'd like to install CM7 on my CF-rooted S2, i have to know for sure:
Is there a way to install CM7 on a CF-rooted device?
Many thanks
Rom manager doesnt work with cf root, so to flash cm7 download the zip, boot into recovery, and flash the zip twice, and it will work.
Make sure you wipe data and cache, and take backups before you do.

Ok, i'll give it a go .
Thanks for the quick response, it is much appreciated!
I restored to 2.3.3 after bootloops in my ICS rom. But now when i go to CWM and select an option there is nothing but the CWM logo in the background. What did i do wrong? Since i cant flash a rom with CWM is it safe to use odin and just flash a stock ICS Fw
You don't have Rom Manager installed/use it by chance, do you ?
Nope dont use it
OK. Something has broken Recovery then (Rom Manager has a tendency to do that if you use it/have it installed on a phone with CWM which is why I asked).
If you're back on GB, you could try flashing a CFRoot kernel in Odin. That would probably give you CWM back. Or you could flash an stock ICS rom as you mentioned. Then you could root. Or not.
Up to you. Shouldn't be any dramas flashing a stock ICS rom in Odin tho, the probs with CWM won't stop you doing that.
Hi All,
I am having trouble with Galaxy S2. Months ago I rooted my phone, installed cwm and installed a ROM into it. Now they have released a new version of the ROM which I want to install it.
This is the ROM:
http://galaxys2root.com/galaxy-s2-roms/resurrection-ics-rom-v2-0-for-galaxy-s2-i9100-best-ics-rom/
however, I am unable to boot into CWM Recovery.
If I do the POWER+VOLUP+HOME button its going directly to Android Recovery
I tried opening the CWM Manager, and I get this prompted:
"This version of CWM Manager should be used with CF-Root v5.0 or newer. It appears you are running a different kernel. Various features have been disabled"
I remember Flashing a Kernel to remove the Triangle Logo on the Loading Part.
So how can I flash the Kernel back? And install the newest updated ROM
Flash cf-root first it seems that you're not rooted.

Flashing the original kernel to remove the yellow triangle also takes you back to stock 3e recovery. You are still rooted though. Reflash the unsecure kernel through cwm manager or if that doesnt work, download ktool from google play and reflash from there.
This will give you CWM recovery without increasing binary flash counter. Reboot into recovery and do full wipe, before flashing new firmware.

flash the CF-root kernel using odin or siyah kernel(for me siyah is much smoother) and everything should be fine, also use triangle away to remove the triangle (u can get in google play for donation to the dev or on XDA for free)
why my device always gets stock when i try to install CWM recovery for my GT-I9100? i try to install the version 6.0.2.9 using odin but my device just boot with the start up "samsung galaxy I9100" then i hear a start up tone but the screen is just black then nothing,i just flash stock rom to back my phone to its normal condition but still want to have a CWM recovery on my rooted device please help me guys.
heres my device>>>>>
AFAIK, you can't just flash only cwm. It comes bundled with a custom kernel. You can try philz.

Haven't tried it myself ever, so read it carefully before acting on it.
