GrapheneOS
Cannot unlocked locked sim card (after entering wrong PIN three times)
- Phone: Pixel 8
- Version/tag: 2024070201
Steps to reproduce:
- Power off the phone and power on.
- Enter wrong PIN 3 times.
- Enter valid PUK.
- Enter two times new PIN, like asked.
- There is a message that PIN codes do not match.
Tried several times, but no luck. I had to put my SIM into a different phone to unlock it.
Yes, after I unlocked the card in a different device with Android 13 (not GrapheneOS) by entering PUK and setting new pin (I entered the same as before).
In my GrapheneOS device, I tried to set new PIN to be the same as before as well as 1111: it always was saying the pins do not match.
Could it be an issue with the SIM card? It's hard to see how it could be an OS issue.
No, it's not possible that the issue is related to the SIM card.
I think one way to reproduce and debug the problem is to temporarily set a permissive USB policy, turn on and authorize ADB, reboot the phone, lock the card by entering the wrong PIN three times, then enter the PUK and try to set a new PIN while observing the logcat.
Maybe I used the wrong subject, because the problem is not related to unlocking, but to setting a new PIN after three incorrect attempts with a locked device.
