iphone-os-4.0In order to try out the new iPhone 4.0 beta, you need to have a developer’s account on Apple in order to install and try out the latest beta OS from Apple for the iPhone, iPod Touch and iPad. But today I’m going to share how you can install iPhone 4.0 beta without UDID registration.

iPhone OS 4.0 beta was released in a developer’s preview event a couple of days ago which brings over 100 new features to the iPhone OS with multitasking being the biggest one!

How to Install iPhone 4.0 Beta Firmware without UDID

Yes, it’s possible! iH8sn0w has shown a way how you can activate and install iPhone OS 4.0 beta firmware without UDID registration on your device. Simply follow the steps below to give it a try:

  1. Decrypt your firmware files and get the rootfs.dmg file.
  2. Open the rootfs.dmg file within the IPSW file.
  3. Then navigate to System/Library/CoreServices and copy over SystemVersion.plist
  4. Now open SystemVersion.plist
  5. Remove the following two lines from it
    <key>ReleaseType</key>
    <string>Beta</string>
  6. Add it back into the rootfs.dmg file, overwriting the old SystemVersion.plist.
  7. Now restore the new IPSW file to your device.

  • slack3r

    I seriously think this is a troll… I've tried everything, even re-encrypting the dmg file with the same key, but no matter what I get an error 14.

    Oh well :/

  • Starky

  • mahan77

    i send u r mail can u repplay plz

  • guest

    Hi,

    change ispw to zip and extract under mac os x.
    decrypt 018-7340-029.dmg using
    vfdecrypt -i 018-7340-029.dmg -o decrypted.dmg -k 62ea9bf9971e6c410231646f916f80330f9cbc1d1c585f0c03dab6b6f7158dc0a9c5efaf

    then open dmg file in disk utility converting it to read/write, mount the dmg and adjust the file as described above. Then save changes and set dmg file back to 'compressed' with the mac os x disk utility.

    Then zip all files back with command
    zip image.ispw *

    then you have hacked ispw. I tried but ispw will NOT restore to my iPhone

  • sandorengholm

    Did exactly what you said, but my iphone doesn't restore either. I get an error 13 in itunes.
    Don't know why, but it doesn't seems like anyone had any luck doing this.
    Somebody who has succesfully achieved an iPhone 4.0 firmware without the use of an UDID registration, please upload it, tell us about it!

  • sandorengholm

    Didn't work. Got error 13 in itunes while performing the restore.

  • kuttor

    Slack3r, I have tried everything as well. I mean practically everything… I think once the DMG is decrypted and those 2 lines are removed, it becomes incompatible.

  • Tom

    Last I checked, iappledev.com were giving away free UDID registrations. I got one :)

    Hit them at admin@iappledev.com to see if they are still going away for free. Good luck guys.

    Tom

  • Blahh

    need udid, email at blahblah1998@hotmail.com

  • tommyanderson1992

    btw, anyone hoping to try this is outta luck, its impossible to decrypt

  • Sam

    Thank you! my name is Sam Webb. I sent you an email.

  • Name

    ih8snow doesn't know what he's saying, just showing off!… when you decrypt a ispw it breaks a checksum associated with the file and to re-associate it takes alot of work.. patching iboot blah blah… instead of doing that I'll just wait till summer .. lol

  • scarfxce

    Sent you an é-mail.
    Hope you will register my device.

  • fwintcmi

    need udid registered

    email me carvinusa13@charter.net

    thanks

  • scarfxce

    Sent you an e-mail too.
    Hope you can get my device registered.
    pls reply .

  • leorenard

    I'm registering UDIDs for free until I have 50 slots left! As of this post, I currently have 69 slots left. I have responded to all that have e-mailed me, although and unfortunately a few of you have not supplied me with a UDID in your e-mail. Please be haste, slots are filling up quickly.

    Also I will note here, as I have told many of you, that this beta can currently only be installed if you are RUNNING ON A MAC. You WILL get an error if you try using Windows.

  • Name

    whats your email leorenard

  • what29

    I found this website that i linked to my name above actually found them in facebook, just click on my name to go there, dont worry, you dont need to be a facebook member. They had me up and running 4.0 right away and i now have complete access to their Apple developers account with my own user ID and password. It was worth it, just my 2 cents for anyone who is in the same boat i was.

  • Alex

    udid sent

  • leorenard

    FYI. I am out of free slots. I'll still register if you're willing to pay $10.00.

    Also, for those I didn't respond to, that is because I no longer have any slots left. I have responded to everyone that has been added for free.

    Also, Sam Webb, is everything working for you now? Perhaps you sent me the incorrect UDID.

  • Chris

  • pramipexol

    How do you repack the files when you have the decrypt and the new .plist file?

    I have done and re-zipped the file many times trying compressed, read/write, read only but nothing is working.

    Any help would be great :) Thanks
