[Lenovo A6000/Plus Questions & Answers] TryoutUser:
Recently I got a notification that there is a new system update for my A6010+.

Pretty small, around ~4 MB so I just start downloading it. Then continue to reboot for installing.

Edit: Recent update name is A6010_S1117_160617_16G_SF_TO_A6010_S1118_160825_16G_SF

Please note:

Already rooted, with mount namespace enabled

No modified system partitions, still in default

and I get these error log:

__bionic_open_tzdata: couldn't find any tzdata when looking for Asia/Jakarta!
__bionic_open_tzdata: couldn't find any tzdata when looking for GMT!
__bionic_open_tzdata: couldn't find any tzdata when looking for posixrules!

As you see, system country and locale still same and not edited.

I don't know what is wrong with that log, can you guys help me?

or maybe this error from Lenovo itself or my device?

Should I disable mount namespace in supersu?

Thanks!
