Install Stock Rom - Galaxy S II Q&A, Help & Troubleshooting

I have installed cynogenmod7 on my Galaxy S2 and now I want to install stock ROM. I tried using odin and it didn't work. Is there any specific way of installing stock rom after installing a custom ROM. Please help.
I have installed CWM as well

Nope just place the phone in download mode and flash file in the PDA section of odin. Few topics below is stock firmware.

You cannot compost CWM .

ClockworkMod
CF-Root includes a custom version of CWM4. I always make custom versions, as the originals often do not take some Samsung specific things into account.
CF-Root/CWM4 is NOT compatible with ROM Manager! Manage/perform your backup/restores from CWM directly or using the CWM Manager application included with CF-Root
I'm sorry I don't know what you're saying. My phone is rooted already I only need to instal clockworkmod to install rom right? Please make it simple.

Make it simple if you root with CMW & Root you get Clockwork Mod thats the method most custom roms use .
Other methods not a clue .

Think jje might be saying keep it simple and use a kernel that has cwm. Chainfires cfroot kernels for instance.
Rom manager...why when you have cwm app already in cfroot.
Edit: like above post said. Cfroot is not compatible with Rom manager.
It's pretty simple.
Flash one of chainfires kernels with Odin. Now you have root and cwm accessible via up+home+power or cwm app.
Download the desired cwm installable package (eg Rom) to your internal sdcard.
Access cwm recovery mode like said above and follow the process EXACTLY as the instructions say in the thread where you downloaded the cwm installable package. Eg Rom
Hope this helps.

Ahh you're making a sense. I thought my tech language was bad do iv can't understand JJ. Anyway thanks guys I'll try the manual way.

THe thing I learned:
Never use ROM manager when using a ROM based on samsung firmware.
Use ROM manager when using AOSP ROM like CM7.
Here I am again guys, sorry to bother you with my quest to change rom.
OK, so I can't install cwm with Rom manager.
I've tried installing cwm using the cyanogenmod guide, with no success. It gave me this ''ERROR: Failed to access device. Libush error: -12"
At this point, I'm desperate to install any rom. So I tried to unroot then install a sercure kernel back in to update official firmware. Even that doesn't work. I can't install the secure kernel. I eneded up installing the insecure kernel just to get the phone to work. So please lead me to something that easy?
Install a CF-Root kernel via Odin.You get root and CWM all included so you can install ROMs and do whatever.Thats what people have been tryin to tell you.

That was just too easy and here I was trying every other method. That thread should be pinned to the first page. Thanks everyone.

SII I9100 rooted OTA update

Hey Galaxy SII people, I need some help with a friend's SII.
I'm quite knowledgeable with custom ROMs and recoveries, but I have no idea what to do with a stock phone.
The phone is rooted and not getting the OTA to ICS. I want to get the OTA, losing root not necessarily a problem.
Can someone give me a hand with this? I have no idea what I need to do.
The phone also has the stock recovery.
I apologize if this has been asked before, but I couldn't find a conclusive, comprehensive answer.
Go to samfirmware and download the update firmware and install it via odin.
All the best.

Flash stock ROM from http://samfirmware.com/ via Odin. Search for galaxy S2 ROMs, just make sure you don't download the dangerous ROMs (the ones with a warning triangle next to them).

Thanks for the quick reply.
I'm downloading a zip now. I flash this with Odin/Heimdall? I thought I needed a .tar and a bunch of other files to flash with Odin.
This won't keep root, right? Is there any way I could get root back after flashing?
Also, will this wipe /data?
Oh, and I have the option to download a ROM for a specific carrier. Does that mean I can't use another carrier?
Edit: While I'm at it, is the stock recovery needed for anything stock ROM related?
Yes download will be in the form of a zip file, once downloading is complete you can extract the tar. file and place in the PDA section of odin. This will not wipe your device, well never has done for me. Yes you will loose root as you have a completely new rom with stock kernel. See the guide for rooting your chosen firmware. As for the carrier i always use the unbranded /open version as this has less bloat ware. All the best.

Make sure you don't have repartition button ticked or play with the pit file if you don't 100% know what you're doing either

Need stock rom zip

Hi I hope someone can help me, I've been looking for stock 3e recovery in zip format and I can't find it anywhere. Any help will be much appreciated
Sent from my GT-I9100 using xda app-developers app
I'd say the best thing to do would be to download a stock ROM from sammobile.com or CheckFUS for PC. This will wipe your phone completely, I know you want a flashable stock recovery, I've never seen one. The stock ROM will remove what I assume you have is CWM.

You have three options:
1. Flash any ICS 4.0.4 firmware with stock recovery here:wanamlite.com/forums/forumdisplay.php?fid=11
Don't flash 4.0.3 firmwares, those have CWM recovery.
2. Flash back your stock kernel, via mobile Odin on your phone
3. Flash stock firmware via Odin

Visit sammobile.com, download the firmware for your phone and flash it with Odin

Odin
In my experience, you can flash any Rom using Odin. And on how to do this, Google is your friend.

[Q] Reverting to stock

Can anyone tell me the best/safest way to get back to a stock GB rom on the ACE?. On Jellyblast at the moment.

Download stock rom of your choice from sammobile and use Odin v3.07 to flash..
You can find some guides around here how to flash via Odin.
And, next time either use the Q/A section or the OFF-TOPIC Thread.
Cheers, I was using the wrong Odin!
