So I recently bought an unlocked international version of the Samsung Galaxy S2, and so far I freaking love this phone. It's staying connected to wifi networks just fine, so I'm glad I haven't experienced that issue like many others have (-keeps fingers crossed-). Also no yellow tint so far.
I am coming to this phone from a Samsung Captivate, and I'm loving the FUNCTIONAL GPS, the front-facing camera, and everything else this phone has that the original Galaxy S should have had. However, I need a bit of help on the development side of things, because I want to flash Cognition as soon as I can.
I'm not a complete noob, but I apologize if I'm asking anything that's already been answered, so please, no "L2USE THE SEARCH FUNCTION N00B, LOLZ" trolling on here.
I followed instructions for rooting the phone just fine, and I flashed ROM's (Darky, Serendipity, Cognition, Phoenix Unleashed, CM7) plenty on my Captivate, so I understand how Odin, download mode, etc. all works.
I've got the phone rooted, downloaded the Cognition 1.6 ROM and currently trying to flash it through ROM Manager. Signature verification failed when I'm in recovery mode. I'm just wondering if there's some sort of step like on the original SGS where I have to flash to stock with Odin, then flash the ROM, etc. It's currently on KE7 firmware.
One more thing, I just realized I don't really know how to get into recovery mode on this phone either. I know Download Mode is Home + Power + Volume Down, what's recovery? Thanks in advance!
Recovery Mode is Home + Power + Volume UP .
ROM manager
Be better to follow the instructions as given for that rom .
Installation Instructions:
I highly recommend flashing the full rom! (updates can be unpredictable)
(If you have problems with the update version, flash the full rom instead)
BACKUP BACKUP BACKUP!!
Download the rom zip from below (don't rename it!)
Put the downloaded zip file on your internal sdcard
Reboot into ClockworkMod Recovery
(don't do this from rom manager, it won't work)
Select Install zip from sdcard
Select Browse for zip on sdcard
Select the zip file you put on your sdcard above

I just love this community!
Yes, I did follow the ROM's instructions. As I did when I was on the SGS. It's giving me "File verification signature failed!" message in recovery. That's my problem, not figuring out how to do the whole process.
Is it because it's Android Recovery 3e instead of 2e, like the problem with Froyo on the first Galaxy S? If so, how would I revert back to 2e recovery if it was 3e stock to begin with?

Yes but that's just my problem, rebooting into ClockworkMod Recovery. It's still giving me the stock 3e Android recovery, which has file signature verification enabled. I'm following the instructions but a few steps are left out because most people on here are more experienced with this phone, whereas I just switched.
On the old one, I would use Odin to go back to 2.1 Eclair and get 2e recovery before flashing a ROM. No idea how to get around file signature verification on this one.

Something wrong then suggest ask in rom post or try another rom .
Basics are as always flash a rom with root and CWM .
Unzip rom if required
Then load rom into memory card boot to 3e or 4e recovery choose zip and install .
You can toggle signature verification off in CWM .
The method works on 3e and 4e for definite .

Nevermind, I figured it out, but what you said helps others who run into this situation. I used the old method of rooting, using CF Root gives me the CWM Manager app and I was able to get into Recovery 4 this way.

Ok this is probably a noob question,
i have a vibrant 2.2 tmobile, i just did the 3e recovery mod so that i could root the phone, i finally got it rooted and Im positive it is (terminal emulator says # when i type su,and superuser is working so Im pretty sure its rooted) so when i go into rom manager and flash clockworkmod recovery it always says it works but i cant get into the new recovery only the stock and i cant backup my original rom, does anyone know how to fix this so i can get into clockworkmod recovery?
Im new to rooting so sorry if this is a extremely noob question.
from stock recovery, select "reinstall packages"
I tried reinstalling the packages from the stock recovery but it takes me back to the stock recovery, Ive tried that many times but i never get the clockworkmod recovery, i have no idea why it wont enter the clockworkmod recovery? Can i install it without rom manager?
Download "update.zip" that is attached to this post....place it on the ROOT of your sdcard (not in any folders)
now this is the voodoo edition of clockwork....we are going to want to disable this to avoid issues (sorry, i dont have a normal clockwork available). so also download the disable voodoo .zip attached to this post.
DONT UNZIP EITHER FILE. DOWNLOAD THEM, AND PLACE THEM BOTH ON YOUR SDCARD AS IS!!
follow these instructions exactly:
1. place both files on root of sd
2. reboot into stock recovery
3. "reinstall packages"
3a. if it brings the red clockwork recovery, move onto step 4.
3b. if you dont see clockworkmod, choose reinstall packages again...if you see it move onto step 4.
3c. if you still dont see it, i cant help you further
4. now that you are in clockwork, DONT REBOOT OR FLASH ANYTHING YET, we need to disable voodoo
5. in clockwork choose "install zip from sdcard"
6. choose "choose zip from sdcard"
7. scroll to the disable voodoo zip and select that...confirm install, select "yes"
8. it should take less than a second, youll see "installation complete". (if you see "installation aborted" dont worry, just move on with the steps...see my explanation below)
9. Reboot before flashing anything, very important
10. you are now ready to flash using clockwork mod
PS - im not sure if youre familiar with voodoo, what it is/how it works....but the disable voodoo zip is just a precaution. im not sure if voodoo is built into this edition of clockwork, or if you actually have to have a voodoo kernel to actually be able to activate it. even though i think you need to have a compatible kernel, its better to play it safe.
with that said THERE IS A POSSIBLILTY THAT WHEN YOU FLASH THE DISABLE VOODOO, YOU MAY GET "INSTALLATION ABORTED"....dont worry continue on with teh steps, that just means that voodoo does not actually exist for you, which is probably ideal anyway
It still didn't work, i must be doing something Ive tried everything but it just wont go to clockworkmod.

Have you tried the toolbox?
http://forum.xda-developers.com/showthread.php?t=954509
No i haven't tried toolbox yet but ill give it a shot.
I had a similar issue...
Are you getting the error "signature verification failed"?
No I haven't gotten a single error message, i flash clockworkmod recovery and it says success, I reboot into recovery i get the stock recovery, so Ive tried reinstall packages several times and i never get an error message although when I do hit reinstall packages it goes through in like 2 seconds but It never lets me into clockworkmod.
Use AIO Toolbox (recomended) -> install USB Vibrant drivers (if you don't have them, included with AIO Toolbox) and flash stock 2.1 rom (included in AIO Toolbox), after that use rom manager (from market) and install clockwork recovery, then download any kernel (for 2.1 rom of course) with root and flash it thru already installed CWM or flash ANY rooted custom rom - that's all (and it will take about 0,5h - not big deal).
toolbox is the way to go it will do everything for you just simply follow the steps from top to bottom. and you will be fine but before you go with tool box do read the noob guide it will surely make u understand the functionality of the toolbox. good luck
Hmmm......
Ok ill give that a try hopefully that will work.

Hey guys,
I was running 2.2 on my vibrant and was having issues with cwm as well. I followed the advice here and it worked great. Flashed Nero v3 and my phone is running like a champ!
Thanks again to everyone for their expertise.

I had this same problem hopefully this works
I have successfully been able to root and install everything on my Mytouch4G just fine, however, when I tried to install my wife's Vibrant, I am stuck. Here is what I have done:
1) I rooted successfully using superoneclickv1.9.1
2) I installed ROM Manager and also downloaded the Auxora ROM to get ready to install
3) When I flash CWM recovery, it says current and latest recover is 2.5.1.2 (concern here that my mytouch says 3.0.2.4 - do different phones install differently with CWM?). When I look at all CWM recoveries I also notice there is two seemingly more current versions available 2.5.1.3 and 2.5.1.4. I have left it at .2 but wondering why all the versions.
4) When I reboot into recovery, I always get the stock recovery and have not been able to get CWM recovery so I am unable to flash my Auxora ROM. I ran update packages numerous times, and get a signature verification error. I have tried a recovery 3e patch that does not work either. I also gave a try at downloading and SDK, but received temp root errors (phone is already rooted).
After reading many posts, I cannot seem to get a direct answer on what I should do to get CWM to actually boot properly, so I can flash a ROM. Someone said to flash the stock JDK rom, but if I can't boot into recovery, how can I flash anything.
Any help would be greatly appreciated.
You need to get a program for your pc called odin to get back to stock. you can find that and instructions on how to use it if you search for the daily updated vibrant bible its GREAT

going to stock eclair heres a a great guide
So going back to stock eclair will then allow me to install CWM recovery then load roms?
Every once n a while I haft do the install packages thing twice before it gives me clockwork green
. Hope this helps.. o n btw u should look at some of the other roms in the bible before u try auxora
yes u should go back to stock eclair for every rom, in my opinion. Then after that do the 3 button combo and install packages and u will have to do it twice and then the green screen will kick in and ready to rock a new rom.
i hope this helps
What is your current firmware?
I see you posted over in the "NOOB GUIDE" thread, you should really try to root using the method posted there and not any one click root apps.
This should be the root method everyone uses:http://forum.xda-developers.com/showthread.php?t=723479
After root your phone recovery should be blue. Choose "reinstall packages" gives you green recovery(this may need to be repeated multiple times to work possibly including flashing CwMRecovery with ROM manager. I recently did it 5 times b4 i got green recovery)Once you access green recovery chose "apply sdcard:update.zip" go into advanced and choose "reboot recovery" This should give you red recovery. Do a nandroid backup and flash away. Good luck!
Another option you could do is to download SGS kernel flasher from the market and flash a voodoo injected kernel with that app. Then when you boot into recovery you will have red voodoo recovery and you can flash away.
Odin to stock the best way to flash a new rom

The stock 2.2 that Samsung distributed with their Kies tool has a recovery that checks signatures. Everything earlier does not check signatures. So either use something earlier to get CWM running, or use a ROM that doesn't have the stock 2.2 recovery in the first place, or mod your recovery using the method described in http://forum.xda-developers.com/showthread.php?t=833423
Using Odin to go back to stock Eclair between your flashes of modded roms has the benefit of taking care of this, and also can clear up left over bits and pieces that may interfere with the proper function of your new ROM.
ok, i followed the instructions and am back to eclair, however, whenever I install packages, it just reboots the phone, not even back into stock recovery. I use the 3 key method and get into recovery, run install packages, and the phone just boots back up...its like it isn't running the update.zip file...
UPD: When i load rom manager and try to reboot into recovery, it says the application superuser permissions has stopped unexpectedly and keeps force closing now....titanium backup wont run now either, my root permissions seem whacked after going back to eclair?
UPD2: I followed instructions to unroot and reroot here: http://forum.xda-developers.com/showthread.php?t=739300
It removed superuser, then added it back again, but I still get the unexpected error and it appears my root is not in place. I am back to eclair, and now need a certain way to get my root fixed, so I can try and flash CWM recovery. Without root working, it is not letting me. My wife hates me now for doing this to her phone, so those of you that are married, I would appreciate your assistance to get back on her good side...before Mother's day...please? =)
Ok, thanks for all the help, however, I am really back where I started. I can only get stock recovery, and for the life of me, cannot get CW recovery to load. I used ODIN to go back to eclair on the vibrant, have a good root on the phone now, and no matter how many times i reinstall packages i cannot get clockworkmod recovery to load, ever. Any more thoughts out there?
I had this trouble a few months back. Things to check before going into recovery:
You gotta have root access.
Make sure you have debugging on
Install busybox FIRST
Try uninstalling Rom manager and reinstalling the latest version.
apply the recovery for vibrant and let it boot into recovery.
When it boots into recovery Don't try to install packages yet. Just reboot.
Look here for the files:
http://forum.xda-developers.com/showthread.php?t=833423&highlight=3e+recovery
When it boots up push the update.zip to the sd card on the phone, not the external card.
Run the script and it should reboot back into recovery.
You should now be able to install packages.
This way has always worked for me.

thanks...It is rooted, but not sure about busybox...the stock recovery is 2e now since I went back to eclair, so not sure i should follow that link as it talks about modifying 3e and making it backwards compatable. I did use that process before I went back to eclair, and it didn't work for me. I have uninstalled rom manager, and reinstalled...and it is different in that it shows a flashed recovery 2.5.1.2, and never asks me for my phone type anymore...it used to ask me and i had to select vibrant....is the recovery supposed to be 2.5.1.2? when I show all recoveries it lists .1, .2, .3, .4 so wondering if I should use .3 or .4...why does it stay at .2?

OK>>> I GOT IT... Thanks to everyone who helped...Here is what was needed:
1) Install ODIN, install back to eclair
2) uninstall ROM Manager, reinstall
3) I needed to select the 2.5.1.2 recovery from the list again (this was important as it somehow knew of the previous load, but files were missing, or something was just wrong.) It finally loaded properly, and asked for phone type again, so selected vibrant
4) I rebooted into recovery, and instead of install packages, i rebooted once, as starkiller suggested
5) After reboot, went back into recovery from rom manager, and this time installed updates, and it showed that it replaced the recovery with CWM.
6) It rebooted into stock recovery however, so I once again selected install updates, and it went right into CWM recovery, and now I am flashing happy!!!
Thanks again everyone...this was soooooo different than my mytouch4g!
If you have the Kies update of Froyo, the 3e mod will sometimes not work. I've gotten to CWM though , but its best to downgrade then flash a ROM from there.
I just wanted to bump this thread because it really helped me.
I've messed around with numerous android phones, and I've never had thie issues I've had with this phone getting into recovery to flash ROMs
Thank you!
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!
-Jeff
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.

Trying to install clockworkmod but I have 3e recovery. I did it through rom manager which was a nub mistake but I didn't know 3e was going to troll me. So it says:
e:failed to verify whole file signature
e:signature verification failed samsung "3e"
I then followed this thread: http://forum.xda-developers.com/showpost.php?p=16909269&postcount=12
and tried the Speedmod kernel to get rid of 3e like the person said but that rom is for the international version and now I can't connect to verizon.
So at the point I am thinking using Odin is my only option but all roms are .zip and not .tar. I am clueless as what I can do. Please help me.
So I tried the Odin method in this thread http://forum.xda-developers.com/showthread.php?t=1026746 and flashed the pit and stock 2.1 files. It passed with green in odin but when I put the battery back in it boots into 2e but says # Manual Mode # at the bottom. I am not sure if that means the flash didn't actually work or what. I am lost now.
Thought I'd update this thread since I finally fixed the problem and sucessfully put Cyanogenmod7 without using the stupid Rom Manager after about 8 hours of work. So just in case someone wants to know what I did. For some reason Odin was not working so I used Heimdall v1.83 and the EB01 Heimdall package and sucessfully flashed to froyo 2.2. I mounted the sdcard and put Cyanogenmod7 and gapps on it.
Now I used Odin to flash the CM7 capable CWM (I think its version 4). Booted the phone into download mode and then used jt1134's ClockworkMod Recovery found in the CM7 fascinate wiki. The wiki says use Heimdall but I used Odin and it worked. The CWM is now blue instead of Red. Next I did a wipe data/factory reset along with wipe cache partition. I selected install zip from scard and choose the CM 7.1 package. Everything went well and it boots into CM7. NOW TO INSTALL THE GAPPS. I thought I just boot into CMW using the volume buttons and power button BUT NO that is NOT correct. In CM7 you have to hold the power button and press reboot and then select recovery AND THEN IN THAT CWM select install zip from sdcard (choose gapps). THIS IS IMPORTANT OR ELSE GAPPS WONT INSTALL. I was bummed for like another hour.
So there it is how to install CM7 just when you think you have been to hell and back with the fascinate. Never again am I volunteering myself to help root and install CM7 on a friend's fascinate. The droid incredible was soo easy!
I know it's been adressed many times in different ways, but the info I found yet is not clear so I need a little help! I am trying to install the latest stable Cyanogen mod, using Gingerbread 2.3.7.
I have a Galaxy SII from Bell that I rooted and unlocked when I got it last november. It came on 2.3.3 and I flashed an official 2.3.4 on it, mainly to improve the battery life (and it worked). I did that using Odin and it went well.
Now I try to install Cyanogen mod through ClockworkMod ROM manager, I download and launch the install from ROM manager but on restart the install fails because of the classic 3E recovery message that says the whole signature cannot be verified.
I was having doubts if my phone was even rooted, but since it is still unlocked and software like Titanium backup runs fine, I guess that confirms it!! I am not sure what route to take from here...
Right now here are the phone details...
GT-i9100 on 2.3.4, FW I9100XXKG2, Kernet 2.6.35.7-I9100XXKG2-CL375027 [email protected] #2
I'll appreciate any help!!!!!!
