Disable and Enable again, wait a few seconds, and if necessary repeat until signal is acquired (mine took three repetitions)ġ4. Go to Utilities and press “Restore Activation” you will get an error, its OK, go back outġ3. Enable it Again, and wait for 5 secondsġ2. The network will change to “Searching…”ġ1. Check if SAMState: Loaded OK, and Disable SAM (Under Suscriber Artificial Module)ġ0. Once rebooted, insert the unofficial SIM, it will say “No Network” this is OKĩ. Copy ONLY the Lockdown folder to /var/root/Library (Dropbox puts it usually in /var/mobile/Documents/var/root/Library/Lockdown, depending on how you preserved your activation ticket)ħ. Unzip your SAM activation ticket previously stored in Dropbox (after you click the zip file select to open with iFile)ĥ. Delete /User/Library/Preferences/ (if its there)Ĥ.

Delete /var/root/Library/Lockdown folder with iFileģ. Remove original carrier’s SIM (or any SIM)Ģ. No need to preserve Baseband! This method worked for me on an iPhone 4 GSM with SAM activation ticket preserved under iOS 5.0.1 and BB 04.11.08, updated to iOS 5.1.1 with BB 04.12.01 and Jailbroken with Absinthe 2.0.1, Obviously you have to start by installing SAMPrefs from the, and I used iFile and Dropbox to restore the Lockdown folder with the preserved ticket, here is what I did:ġ.
