809924 - MozMobileConnection misbehave on first run - lockscreen stay in "emergency calls only" even with a sim card

Status: RESOLVED DUPLICATE of bug 806307

(Firefox OS Graveyard :: General, defect)

Description

[Alexandre Poirot [:ochameau]]

For some reason the MozMobileConnection is broken.
On firstrun of b2g on a device (unagi) with a sim card, the lock screen stays in "emergency calls only" mode and the SIM PIN dialog never show up.
That's because MozMobileConnection.cardState is null and stays null.
The only way to get it working again is to switch on and off the airplane mode, or restart b2g process.
This issue prevent from asking the SIM PIN and having any Mobile connection working.

Need to be confirmed, but if it doesn't happen only in my build, definitely a blocker.

I don't have unagi to test it, but this sounds like being caused by Bug 806307.

Hi Alexandre, 
Can you enable the debug log for us?
it's in dom/system/gonk/ril_const.js, flip DEBUG_ALL to true.

Sure, here is a log for a device booting with the locking stuck in "emergency call".

And here is the exact same device but I then switched the aiplane mode on and then off so that the lockscreen works and display "emergency calls only (SIM PIN required)"

Hi Alexandre

Thanks for providing the log. :)
I've checked the log,

For PIN lock isuse it should related to Bug 806307
The pinRequired message is sent in line 802
but system-message-listener-ready is received in line 838. 
so seems gaia cannot receive the pinRequired state so it cannot pop up PIN dialog.

And since the SIM is locked by PIN so it cannot register to network, 
that's why it shows emergency only.

Thanks for reporting this.
I'll duplicate this to Bug 806307,
or if you have different opinion please feel free to re-open it.

Vicamo, it's not clear to me how this bug is a duplicate from bug 806307. Can you be more explicit?

Hi, Mounir
Those icc-related messages (cardStateChanged) are sent too early, before gaia is ready to handle them.
(notice that the SIM card events will still be notified to gecko even the radio is still off).

When gaia is ready to receive messages, it should send 'system-message-listener-ready' to gecko.
In these two bugs, those icc messages are sent before receiving system-message-listener-ready, so I duplicate them. 

Does this make sense to you? 

BTW, my name is Yoshi, not Vicamo
(It's okay, many people got confused :) )

Arf, sorry Yoshi. I don't know what happened. First of all, I was pretty sure the comment was from Vicamo and not from you and I thought you marked this bug as a duplicate of bug 804966 but you actually marked it as blocking bug 804966 which makes way more sense actually :)

I will put that on the fact that it was Sunday morning ;)

Sorry again for the confusion and the noise.
