Hello Everyone,
There's a new issue floating around and i want to bring it to your attention.
Description:
- iphone 3GS, iphone 3G with firmware 4.0/4.0.1
- Activated using a phonebook SIM or 16-in-1 SIM or 6-in-1 SIM or something similar. A lot of people are using these because they don't have a legit carrier SIM
- After activation, the device is jailbroken with jailbreakme.com and unlocked with Ultrasn0w.
- Now come the interesting part:
** when the user switched out SIM and put in the carrier SIM, the iphone will immediately switched to the "slide for emergency" screen (like the phone not activated) and it will say "Invalid SIM" on the screen. However, the device is getting signal from the carrier (unlock is working).
** When the user remove the carrier SIM, the iphone will go back to the springboard.
** When the user put back carrier SIM, same problem again.
Resolution:
If you are having this issue, the work around is to get the lockdownd from a working hacktivated iphone 3G/3GS respectively. The lockdownd file is located in /usr/libexec. Copy the the file to the device you are having problem. You can copy file using utility such as ifunbox or something similar. The permission on the lockdownd file is 755. If you are copying the patched lockdownd over the existing one, the permissions should be in-tact.
If you do not have a working hactivated lockdownd file, you can patch the existing one by using bspatch. The patch file is located in the pwnagetool bundle for iphone 3G and 3GS. (** we will elaborate more on this later).
Note: Seems like device activated using a legit carrier SIM doesn't have this problem
