Hey guys,
I'm on holiday and I forgot my USB cable. I want to install a custom rom like Cognition and now I'm on XXKE2.
The problem is, I applied CFRoot (I think it was that one) but then I flashed the normal kernel back so there was no ! sign.
Question: Can I get CWM so I can flash Cognition without a PC but with root?
Thanxxx!
Try an app called darkyrom 2, from the market, it may let you flash a Cwm kernel and from there you can do nandroid backups and flash custom roms.
It may not work, but it's worth a try, the app let me flash a modem away from pc, im not on darkyrom but i do have a cwm kernel.

If you have a way to get the zImage of a kernel containing CWM onto your phone and you have root, you can flash that kernel with no problems.
First try getting the zImage onto your phone, like transfering if from your PC (as I read it you only forgot the USB cable) via WiFi.
Then install (if you don't have it already) a terminal app from the market.
Open a terminal session and enter:
Code:
su
dd if=/path/to/zImage of=/dev/block/mmcblk0p5 bs=4096
reboot
After that you're running whatever kernel was in that zImage.

yesterday iwasaperson was extremely helpful to me. Thanks. I took my fascinate back to stock 2.1 and allowed it to update to 2.2. I then rooted my phone by flashing CWM recovery using ODIN. (red version) I had installed two files to root of drive one update.zip and the other for rooting the phone Su-----.zip. I ran them using the red version and restarted the phone. The phone is now rooted but I can't get back to CWM recovery.
I tried the following: I have ROM manager and flashed CWM but it wom't take. If I try to go into recovery I get the stock Samsung blue menu. I am thinking I need a different (CWM recovery comptabile) kernel or mod to get this to work.
Can someone help?
You need to flash a kernel other than stock, rebooting with the stock kernel will revert back to blue recovery

why dont you just flash CWM in odin again?
I have flashed CWM again with odin. It still won't take

This (though in reverse order).
You need to reflash CWM by odin, go into Odin immediately upon the first boot (not using Rom Manager!), and flash a new kernel from the SDcard. The stock kernel will trash CWM if it gets a chance to boot.
saf66. any ones in mind and where I can obtain them. And as if I weren't asking enough questions. (Sorry I know I am) Methods to flash them?
Or any others of you please
Go into development at the top of page open stickies and nitsu has a list of kernels,a well as roms

my computer is dead and I don't know when ill have access to a computer next. was messing with my phone and ended up needing to go back to stock eb01 with out root. I thought there was a rom that had root access and su built in. but I can't remember. anyone know of anyway to gain root without computer access? thanks.

IIf you have any rom's on your sd like com rom, it contains root but you must have a non stock recovery to flash it with out a pc.
So if you have an aftermarket recovery you can just download a rom that contains root...most of them now a days do, just boot into recovery wipe everything and flash.
At that point you'll have root and you'll be operational until you can get to a pc to get you the rest of the way. If you don't have any rom on your sd just download it right from your phone..I recommend com rom 2.0 and then if your want the 2.1 patch...ths will get you root, the rom, otb kernel, and a very functional phone.

I have com rom already. having trouble with a recovery that won't stick. I need Odin to get the recovery to work right?

What recovery are you using right now? I believe there are CWM 3 zip files you can download through ur phone & flash.

Recovery is over written by the stock kernel, odin is needed to flash stock vzw files, and recovery for the first time....you say you have com rom already...well just odin recovery (3/30 fix all, otb 3.x x, or times infinity 3 x.x x) any should work. Run odin and after its done immediately 3 finger boot into recovery then wipe data, cache, and dalvik, and flash com rom (it contains a kernel so recovery will be stuck and unless you need to go back to stock or screw something up you shouldn't need odin for a while)...reboot and you have a permanent recovery

Hello
I tried hard to install CWM but couldn't
I got the cf-root from
http://forum.xda-developers.com/showthread.php?t=1103399
downloading and trying both CF-Root-SGS2_XW_XEF_KJ2-v5.0-CWM5.zip
and CF-Root-SGS2_XW_XEF_KJ2-v4.4-CWM4.zip
thinks you may need to know:
-I updated my device to 2.3.5 using kies
-my Kernal version 2.6.35.9-I9100JPKJ2
-I root the device using: SuperOneClickv2.3.3
- when I used the odin to download the CF-Root-SGS2_XX_XEO_KI4-v4.4-CWM4.zip couldn't transfer data to device
So I don't know what to do?
You could use mobile odin as you have root
Sent from my sgs2 running cm9 using xda app
just odin any rooted kernel like siyah or speedmod, they come with CWM
Exactly, Set your phone in "download mode"
connect to odin
and flash by choosing the kernel tar file as PDA
thanks for replay
But I used the stock one and I would like to keep it
As far as I know, you need to flash whole kernel if you wan't to get cwm

I am having a little bit of trouble trying to solve a problem with CWM. I rooted my phone earlier last year and decided to try some roms lately but I am now in a bad position as CWM is telling me I have a different kernel and I am unable to get the option to restore my previous rom backup. I keep hearing to use Odin which I previously used to root my phone, to update CWM in the kernel to the latest version. Normally when I update the kernel it is quite simple - just install from the zip on sd, but Odin is a complete mess to understand. I am probably approaching this incorrectly. What can I do to restore to my previous CWM backup?
Try using ROM Manager to flash CWM, this might solve your problem.

Thanks for the reply. Do I flash the CWM.zip (current version) as a rom in this app or do I use a different option?

ROM Manager - Flash ClockWorkMod Recovery - Samsung Galaxy S2.
Sent from my GT-I9100 using XDA
That did not seem to work. Rom Manager stops working and after awhile it asks if I want to wait or stop the program.
Is there a way to get this to work through odin? I am unable to reset to the default firmware as some files are irretrievable now.

Do not use rom manager. Flash cf root kernel with odin and you'll have cwm recovery.
I was going to root my S2 today as I have had it for a while and want to root and update my rom or install a custom rom. CF hasn't made an insecure kernal for KH2. A few users had the same problem and used KH3 as stated by CF but some ended up running into difficult problems and some had no problem.
Should I use KH3 to root or should I use another method. I only want to root gingerbread so I can back up app data. I might then factory reset and update the stock rom or flash CM10 and then restore the app data.
Try using siyah kernel, same process...flash via Odin but with siyah there is a .zip and a .tar make sure you choose tar

Firstly, CF-Root doesn't use insecure kernels, it uses modified kernels, but thats OK. Here is a link to a one click root solution made by a reputable developer: http://forum.xda-developers.com/showthread.php?t=1125414
Scroll down the first post and you shall find the instructions. I believe the second post has a link to all the insecure kernels, including KH2 (I checked), and if you scroll down that link a little more, you shall find your original KH2 kernel to flash back to stop the yellow triangle showing at boot, but if you are immediately flashing a custom ROM, that is fine.
This method however will not grant you ClockWorkMod so you can flash a kernel such as Siyah Kernel, make sure to download the GB kernel, not the latest ICS kernel! Here is a link to the GB kernel: http://www.gokhanmoral.com/gm/2012/03/19/siyahkernel-v2-6-14/
Flash this using Odin. Put the .tar file in the PDA section on Odin once you have put your phone in download mode, killed off any Kies processes on your computer, and click start. This will add a new custom kernel to your phone, granting you ClockWorkMod Recovery, allowing you to flash a custom ROM.
Before progressing any further, back up your phone by booting into CWM (home button + power button + volume up button).
Also, download EFS Pro: http://forum.xda-developers.com/showthread.php?t=1308546 This tool backs up your EFS folder which contains your IMEI which can be damaged easily when flashing custom ROM's and you don't want to do that!

What if I want to just update my S2 to the latest stock rom and not have a custom rom. Do I have to flash back to the original kernel to be able to update the stock rom? Once I update to the latest stock rom, will my phone still be rooted or will I have to root it again?
You would have to root it again. But Chainfire should have all the modified kernels for 4.0.3 ready for your use anyway.

So after I flash the insecure kernel to root my phone (gingerbread), shall I flash back to the original kernel?
Sent from my GT-I9100 using xda app-developers app
Yeah it stops the yellow warning triangle being displayed at boot. Your custom flash counter will increase but it can easily be reset by buying a USB jig off eBay.

So I should flash back to original kernel and then update to ics and then root again?

Or just flash Siyah kernel via Odin and then flash a custom ROM which should automatically root your phone. If not, just find a CF-Root kernel for your firmware and all shall be good.
Sent from my GT-I9100 using xda app-developers app
There isn't a CF-Root Kernel for me which is why I created this thread to ask for the second best method to rooting a gingerbread S2 or if I should use KH3 CF-Root Kernel to root. I'm only rooting so I can back up app data using titanium. This is my first time rooting and flashing and I was going to root using CF-Root until I couldn't find a modified kernel for me.
