02-15-2011, 12:16 PM #1How to remove Passcode without Restore
I jailbroke my iPhone 4(iOS version: 4.0.1) yesterday and it was working fine.
Used: Jailbreakme.com to jailbreak and UltraSn0w to unlock.
A few hours later (after a few restarts and connects to iTunes), I suddenly saw that it started asking for a Passcode.
I had never set one for this phone ever so Iím completely stumped as to where it came from. Itís not even the simple 4-digit one but the longer one. FYI- I also have another iPhone 4 (on 4.2.1).
I need help in figuring out:
1. (Less important)- How the heck the passcode got set (I know for a fact nobody else touched the phone).
2. (More important)- Can I erase/change the passcode WITHOUT having to restore the phone. Apple will restore the phone to 4.2.1 and the jailbreak & unlock will fail.
I tried connecting it to my home laptop and was able go to a previous backup (which I know for sure did not have a passcode) and even after successful restore of the backup, I still get the passcode window. Also, not sure if the backup really restored as I still see the funky pixels on startup splash screen (which I read somewhere is the jailbreakme bios related code).
Today I tried connecting to my office computer (which I had never used before) and it says iTunes could not connect as the phone is locked with a passcode.
So, I'm hoping I can do something on my home laptop to get out of this.
Will highly appreciate any help I can get.

The only way I know of is to restore, but there are other ways. The Jailbreak must've locked you out as a prank or something. There are better ways, but this is all I know of.

you probably set up a microsoft exchange email. it adds the longer code as added security. use your Exchange email password.
restoring from a backup will just re enter the passcode lock from Exchange.
there is no way to remove it unless you delete the email account from the phone do a firmware restore and NOT restore from backup
note: you probably want to make a new backup without the Exchange email entered. IF you have the correct passcode, remove the email acccount from the phone, make a NEW backupand delete the old one.

Have someone call your phone, answer it. Then while in the call goto settings and turn off or change the passcode

Super Thanks Madman604x!!
Yes, it was the Outlook Exchange setup! I had followed its steps blindly and didnt realize that what I entered as my password was in fact taken as device lock- stupid me , and thanks again for the suggestion.
Thanks Broomhead too- Your suggestion should have worked too- and will remember if I need it ever. I'm puzzled why google didnt bring up your suggestion, which is so simple. I saw quite a few people asking something like- "My son/daugher/dog set a passcode which nobody now knows, how can we remove the passcode without having to restore", but restore was the common answer.

I actually wrote a mobile substrate add-on for this.
What you need:
- Access to a windows computer (for i-funbox)
- Both files at Index of /nopasscode
What to do:
Copy them both to /Library/MobileSubstrate/DynamicLibraries/
Enjoy having no passcode
*****This does not reset the passcode, it just tells iOS that the device has no passcode...******iDevices: Lots, most jailbroken
