DO NOT UPDATE YOUR BASEBAND IF YOU HAVENT ALREADY!
YOU DO NOT NEED TO ANY LONGER!

Users that have already updated can use this CFW to restore there devices. But they have to use redsn0w after restoring to jailbreak this jailbroken Firmware. I dont know why, but Cydia wont crash after jailbreaking the CFW!

Here is the download link!
iPhone 3G CFW iOS 4.2.1 WITHOUT Baseband Update!

If Cydia does not work fine follow these steps:
– Open SSH Connection via Cyberduck
– Insert cydia_1.0.3366-1_iphoneos-arm.deb in /tmp
– Now open your terminal of the SSH Client and paste
dpkg -i /tmp/cydia_1.0.3366-1_iphoneos-arm.deb– After this paste killall -HUP SpringBoard to restart your springboard!

1. Hey, is there any possibility to hacktivate the iPhone 3G with the cfw 4.2.1? Thanks dude!

4. is there a cfw for 4.1 iphone 3g?

5. As I understand it’s easy to make CFW without baseband with MAC PwnageTool. But i don’t have it and cant make it virtual OS because of old PC hardware. So all I need is CFW from PwnageTool with Cydia installed, not hacktivated, clean and clear for my 3G with iOS4.1 with old unlockable BB:) This realase is what i want or not?! How do you create this?!

   After I read your post, i’m curious doesn’t redsnow JB update BB? You suggest to restore with your CFW and then JB with Redsnow, why it’s not already JB with PwnageTool?! As I know, I cant use redsnow because of reason i dont want to update baseband!

   Thanks!

   Best wishes from Lithuania! 🙂

6. What can I say… You right. Baseband wont update but… It’s unbelievable unstable build… Sprinboard crash a lot, for etc when i receive SMS (bitesms alert)… Build kernel wont support by Bootlance (it should if CFW made with PwnageTool). Part of icons on home screen sometimes disappear and even springboard restart or reboot wont help… Internet tethering wont work even i try to patch commcenter… This is peace of shit! 🙂

   Thanks for your work… but i dont know why it’s so bad my friend.

7. You was right mate. When i downgrade to 3.1.3 i remember who iPhone 3G really is!!! 🙂 Now it’s quite fast and stable device… Yes, perhaps it’s a last good iOS version for 3G…

   Thanks 🙂

8. Hi,

   I did jailbreak/unlock since iOS 1.1.4 but never had such problems as now. Please help!

   iPhone 3G old baseband 05.13.04

   I was jailbroken and unlocked on iOS 4.0 and tried your proposed method:
   UNLOCK iPhone 3G 4.2.1 WITHOUT BASEBAND UPDATE

   I used pwnage tool to enter DFU mode, then restored the CFW via iTunes (newest version). Was not successful. Error message: unknown error 1600.

   I tried several times but I couldn’t make it work.

   Then I tried the official way and let iTunes update to 4.2.1 – I was hoping that I would be able to JB / unlock later. Now I am stuck with the “connect to iTunes” screen and it doesn’t let me continue / complete the FW-Update since I have no official SIM card supported by Apple.

   What can I do!??

   Thank you for your time, will donate when solved!

9. Great!!
   I am back on 3.1.3.
   Restore worked this time through iTunes without 16xx error, using your custom firmware 3.1.3
   As far as I remember i did it from Recover mode, not from DFU mode. It would be nice if you could add this information to your howtos for other users.

   Thanks again for your quick and continued support!! Will donate next…

   • OK, as I said I am back on 3.1.3 jailbroken, however, I messed my baseband up before, it’s now on 05.15.04 and therefore can’t unlock with ultrasn0w. You are saying I can get to 4.2.1 UNLOCKED with this CFW restore:
     UNLOCK iPhone 3G 4.2.1 WITHOUT BASEBAND UPDATE.
     I didn’t succeed, iTunes unknown error (1604) occurs.
     What’s the exact preconditions for this method? Does it work from 3.1.3 or do I need to go to a different iOS version first? Which one? Do I start the CFW restore from DFU mode, Recovery mode, or what?

     A step by step tutorial and exact description of the prerequisites would REALLY help.

     Thank you so much.

BlackDoor provides two series, first series looks like iOS 4/5/6 and second series looks like iOS 7/8.

Iphone 3g 4.2 1 Custom Firmware

Both series are in two versions: Normal and Unlocked.

Select BlackDoor Normal version if you can legitimately activate you device via iTunes and you don’t need carrier unlock.
If your device is factory unlocked or you are using iPhone with the official carrier that sold you the device.
All other users should choose BlackDoor Unlocked firmwares because they need carrier unlock.
BlackDoor unlocked firmware need Push Notifications patch after the installation. Recommended visit pushfix.info but you can also visit others.
