Full flash the build
- Go to settings, Date & Time, and change timezone to Atlantic Ocean
-  disable 'Set time Automatically'
- Change time
- Change timezone back to 'America'

Screen goes dark, and often it need to be reflashed.  Otherwise, the phone reboots itself after 10 minutes or so
Timezone is changed

Triage: this is not related to settings app, regression window wanted then we'll put to the proper component
putting qawanted for branch checks to find all that's affected, but also leaving regression window wanted tag.

We should treat this as an urgent.

Issue does NOT occur on Flame 2.1

Changing time zone and time before switching back to the original time zone does not cause phone to freeze. Behavior appears normal.

Issue DOES occur on Flame 2.2 and Flame 3.0

Changing time zone and time before switching back to the original time zone causes phone to freeze, making it necessary for phone to be reflashed as the device does not move past Thundersoft splash screen if battery is removed then replaced.

Issue appears to be caused by changes made in Bug 840790
Ryan, can you take a look at this please? This issue could have been possibly caused by the landing for bug 840790
QA Whiteboard: [QAnalyst-Triage?] → [QAnalyst-Triage+]

Questions like that should be directed at the patch author, not the person who landed it on their behalf.

I just tested the STR with and without the patch for bug 840790 and I am able to repro with the patch applied :(

I don't fully understand why exactly it is failing, as the patch only modifies a json file on shared, or why why it fails on settings and not in ftu for that matter.

The quick fix for the crash would be to revert the commit, but I'm not sure that would be the ideal solution, as we (at least I) don't have any idea of what exactly is the cause of the problem.
But reverting, at least, fixes a potential crash and gives us some time to re-fix bug 840790 without the crash.
Flags: needinfo?(fernando.campo)
Attached file No errors log
log for the STR once the revert is applied, no crash detected.
Attached file crash log
log for the STR with the patch for bug 840790 applied. 
End up crashing
what do you suggest?
Does it have any test cases attached to it?
Or should I resend the patch testing for this bug along with the previous fixed one?
My recommendation would be a backout. 
The original bug 840790 wasn't a blocker, so getting rid of this regression seems to be more important.

I don't know about any test case attached, and the STR (change region + change time + back to original region) seems to me like an edge case, but I'd rather see a patch for 840790 that doesn't break settings.
FYI, this was discovered when writing an automated test case for bug 1118054
Duplicate of this bug: 1129308
fcampo, I think it's because it's cross referenced with the time zone in gecko.

I think you'll need to do an update on the gecko files as well.

That's just my guess.
The commit that causes this bug needs to be backed out asap.
Keywords: qablocker
I am working with mhenretty(Thanks!) to get this backed out, I am really surprised this has not happened till now.


PLease note these kinds of regressions have to backedout immediately so we do not affect a lot of folks!
Fixed by backing out bug 840790.

Yup, this was just a few commits before my backout. Let me know if today's build is still failing.
This issue is verified fixed on Flame 3.0 and Flame 2.2.

Results:  The phone does not freeze up when changing the time zone.
