Yes, you do have to go back to 2.1 before being able to flash any custom rom.

Guys,

I have resolved this many many times... Just follow these steps -

Pre-requisite - Enable USB debugging on your phone and connect it to your pc.

1. Root your phone using SuperOneClickv1.6.5-ShortFuse. You can get it at 'http://forum.xda-developers.com/showthread.php?t=803682'

2. Go to this thread and download the two files 'http://forum.xda-developers.com/showthread.php?t=833423' - '3e_recovery_installer.zip' and 'update.zip (1.34 mb)'

2. Run install.bat from 3e_recovery_installer folder to rectify the the recovery signature checking.

3. Keep the just downloaded update.zip (1.34 mb) in your internal sdcard and boot under recovery. Select reinstall package option. Update.zip will get installed and phone will reboot.

Its not done yet.

4. Now get the actual clockwork mod recovery update.zip (1.72 mb). You can get this using ROM manager. Now put this update.zip (1.72 mb) in your internal sdcard and boot under recovery. Select reinstall package option. Update.zip will get installed and phone will reboot and will be back in samsung recovery mode. Select reinstall package again and bang... You should now be at cwm recovery :)

Did this help?

Before installing a custom ROM, it is not mandatory to go back to stock 2.1. Generally it is just recommended when you are going from one custom ROM to another custom ROM and by going back to stock you avoid taking ghosts (issues) of one custom ROM to another.

So if you follow my instructions to resolve your cwm recovery for Stock 2.2, you should be good to go to Simply Galaxy/Sweet Honey 2.7.1 without going back to Stock 2.1.

Hope this helps...

Its a normal occurrence after upgrading through Kies to 2.2. The 3e recovery always used to work for me regarding the signature verification error. Accept the last time I tried it about a week ago it coukdnt get it to work for whatever reason.

So what I did was use odin & revert back to 2.1. Then root using one click root. Then just flash a 2.2 rom in clock work, Bionix for example. Then you will on 2.2. You will have no problem with the signature verification this way. Gluk

Default dissable signature verification

DISABLE E: SIGNATURE VERIFICATION ON SAMSUNG VIBRANT

Here goes steps to install this modified 3e Recovery:
PREREQUISITE

Working USB connection between your Vibrant and computer. You may setup ADB or install Kies on your computer.
INSTRUCTIONS

Disclaimer: Proceed at your own risk. We are not responsible if your device gets bricked or damaged during the process.

1. Download Modified Recovery 3e for Vibrant on to your computer and extract it’s content.

2. Put your Samsung Vibrant into “USB Debugging Mode”. To do it, go to “Applications”—> “Settings” –> “Applications” –> “Development” –> and check the box “USB debugging”.

3. Connect the Vibrant to computer via USB cable.

4. Run the “install.bat” file located in the extracted content.

5. Wait till the process completes.

That’s it. Your Vibrant should now have modified 3e Recovery that disables signature verification. You may now root the Samsung Vibrant or install ClockworkMod Recovery on it.

now try rooting with one click or manual
