    mY ipad2 is original unlocking from my country meant no factory unlock.
    In order to restore ipad2 version 6 back to ios 5.1.1 (i have test it four times) it ok*
    note that i have test it to restore from 6 to 5.1.1 *it can;
    we can restore (after downgrade from 6) 5.x and to 5.x again by using only redsnow tool
    *not from itune.
    we can restore from itune back to version 6 again without baseband update on ipad2 .


    **
    Tool:
    A/tiny umbrella latest version (allow access throught fire wall) to check shsh(4.x,5.x).,ECID(dec,hex),serial number of ipad.
    B/Itools or ifunbox to export all apps and important stuff.

    3 second then other finger hold home button for 7 to 10second then release lock button while still hold home button 15 to 20 second
    *we will see on redsnow (DFUmode )-> click ok(waiting it restore) .finish by just leave it(the restore procedure take two time one
    for 4.x another for 5.x.)
    Error service non start can fix by just change usb port to another port. done

    slide all apps from left to right we will see bass icon is mute so -> click it to un mute .done
    ERROr fix Ex008...mean usb defect invalid *so we need to remove apple software, itune , replace dock usb if it too old ,scan virus ,update window*
    then restart pc ->connect ipad to pc check usb is working by show folder option ,then install itune latest version .that shoud work*
    to locate shsh save after fecth to redsnow ,first click folder ->oranized->folder..option ->view->show hidden file extention ->apply it and locate on C:\Users\our pc name\AppData\Roaming\redsnows




    Reset ipad2 by erase all content and setting after finis *now goto jailbreak with redsnow just one click on jailbreak.

    Ok for me I just change USB port it work .for my idea the way service did not start because of malicious to USB so it cann't connect to red snow during it start or another reason you used to try restore to 4.xto 5.x after downdrading from 6. so in order to make clear our USB work fine try out to remove apple UBS software in control panel on pc and software relate software including iTunes but make sure you copy your iTunes library to your pc beware lost your application ,ok.make your pc upto date by update of PC software and install and scan all virus .Then restart computer ,now plug in iPad then you will see notification on pc about installing apple USB .when it is finish you will see auto run folder it means your iPad USB is pure .now install your iTunes back and run your iPad on iTunes to confirm it reconight without any defect .ok to run red snow now and close your iTunes . For my test it work .thanks
    Oh I forgot before doing this restore your iPad to iOS 6 from iTunes first .then manage the USB concern

    A "Service won't start" error indicates an issue with the iTunes installation on your PC. It is not aproblem with the iPad. It is indicating that the Apple Mobile Device service is crashing / failing for some reason.

    I would recommend a full re-installation of the latest iTunes on your PC. Also, ensure you are using a genuine Apple iPad cable (not a cheap 3rd party one), and you are not connecting via a USB hub, but directly to the PC. Try a differnet port if the problem persists.
    Also, it is worth disabling all anti-virus / malware tools whilst you are trying to restore as these can interfere with USB communications.

    You cannot. It is simply not possible. Blobs are highly secure and cannot be faked or bypassed.

    I'm afraid that you'll have no choice but to wait for an iOS 6 jailbreak release in order to jailbreak your iPad.
