Blocked SIM card keeps on asking for PUK

[Michael Zanetti]

I managed to enter the wrong PUK for a SIM card for 10 times in a row and the phone keeps on asking me for the PUK. It always says that this will be the last attempt even though it's too late already.

Instead, it should say that this SIM card is rejected and only emergency calls are possible.

Reported on

This is krillin, with RTM image 21.

@Michael

Tsk, tsk, tsk... No device or image details!

Depending on the device, we may not get the number proper number of PUK retries left. Pretty sure this is a known issue with MTK-based modems, and we have potential fix.

Pretty sure this is addressed by:

https://github.com/rilmodem/ofono/pull/169

[Tony Espy (awe)]

Re-assigned to me, as the pull-request is awaiting review. It's unclear though if this is high enough priority to roll out as an OTA update prior to our vivid -> RTM change.

[Alfonso Sanchez-Beato (alfonsosanchezbeato)]

@mzanetti, would it be possible to get the output of the list-modems script? To do that:

1. Insert the blocked SIM
2. Make sure you can adb the device even with a locked screen:
sudo touch /userdata/.adb_onlock
3. Reboot
4. Insert a wrong PUK once
5. Execute:
/usr/share/ofono/scripts/list-modems

and please attach the output of the script to the bug (do not forget to remove any private information: serial numbers and phone number).

@Tony, the PR you mention would make as know the remaining retries from the very beginning, but inserting the PUK once should give us the same information. So the best thing to do for the moment is let mzanetty follow these instructions and that would confirm if this is an ofono or a unity bug.

@abeato: Here's the output after entering a PUK for an already blocked SIM card.

[Alfonso Sanchez-Beato (alfonsosanchezbeato)]

@mzanetti, definitely looks like an ofono bug. The PR pointed out by Tony should help, but anyway I'd like to gather more traces. Could you modify "/etc/init/ofono.override", changing the "exec" line with the following 3 lines:

<<
...
env OFONO_RIL_TRACE=""
env OFONO_RIL_HEX_TRACE=""
exec ofonod -d -P stktest,provision,sap,udev,dun,smart,hfp
>>

then do exactly the same steps as in comment #5, and attach syslog ?

Sorry... this didn't work out well, here it is a bit nicer formatted: http://paste.ubuntu.com/10689457/

[Alfonso Sanchez-Beato (alfonsosanchezbeato)]

@mzanetti, thanks for the log.

It looks like, contrarily to what happens when there are remaining retries for the PUK, the number of remaining retries is not returned in the response to RIL_REQUEST_ENTER_SIM_PUK.

https://github.com/rilmodem/ofono/pull/169 should certainly help.

I have attached an ofono binary that includes this change. @mzanetti, mind giving it a try?

Please do:

$ adb push ofonod.gz
$ phablet-shell
$ gunzip /tmp/ofonod.gz
$ chmod +x /tmp/ofonod
$ sudo stop ofono
$ sudo cp /tmp/ofonod /usr/sbin/
$ sudo reboot

After the reboot, please paste output of

/usr/share/ofono/scripts/list-modems

After installing the patched ofono binary, this is the output of list-modems:

@Alfonso

Have you confirmed whether or not this works on arale?

[Alfonso Sanchez-Beato (alfonsosanchezbeato)]

@Tony

Yes, I checked in both krillin and arale.
