    I'm get an error when I try to install 5.1 (OTA) on my 2012 Nexus 7

    I've tried
    Wiping cache
    Connecting Power
    Wifi enabled \ disabled
    Seting Date manually & from network.

    All failed ..

    The log files contain the following :- {

    __bionic_open_tzdata: couldn't find any tzdata when looking for localtime!
    __bionic_open_tzdata: couldn't find any tzdata when looking for GMT!

    local is [en_GB]
    stage is []
    reason is [(null)]
    can't open /dev/tty0: No such file or directory
    ...}

    System Information:-
    FCC:ID MSQME370T
    IC 3568A-ME370T
    Model Nexus 7
    version 5.02
    Kernal 3.1.10-g6ff7a51
    Wed Dec 10 19:55:59 utc 2014
    Build LRX22G

    NB: Never been rooted & only has apps from the app store
    > 60% free space.

    Has been pretty much unusable since 5.02 was put on it - Wiping the cache helps, but doesnt seem to be a permanent fix.
    NB: Only takes a second to wipe the cache, notice many reporting it takes ~15 minutes. But only ever takes about a second for me.

    Any ideas ?

    What method have you used? Is this a "proper" OTA update or did you try sideloading?

    I dont have any apps disabled, and I have deleted all but essential play store apps. None of my google apps have been deleted, stopped or disabled.
    This is a regular OTA upgrade, prompted by google.
    I'm gonna try a Factory reset, and if that doesnt do the trick a Hard reset - probably over Easter; I'll report results back here.

    Re Sideloading - Not sure why I'd want to try that, I dont have a problem getting the OTA update or downloading it onto the device, its the install thats failing - Why would sideloading fix this, would downloading the same OTA upgrade and sideloading the install give me different results, its the same install after all. That being said, I'll probably try that if everyting else fails !

    Hi

    The OTA to 5.1 on my nexus 2012 was successful, but I had done a factory data reset (from settings) on 5.0.2 (which improved it quite a lot) before installing from the OTA download.

    I appear to be having a similar problem, with no apps disabled, plenty of free space, etc. and am able to download the update, it just fails to install. I'd say a reset is on the cards for me, too. Sounds like a great way to spend part of Easter Monday!

    Just did a Factory reset, then updated apps from backup, downloaded the OTA update and tried again - still failed, still getting the same error in the logs.
    Did the same for a Hard reset, this time downloaded the OTA and updatd before apps had updated - still failed, still get the same error in the logs.
    So I gues I'm sideloading. So thats me Gin & T and my tablet sorted for the evening
    Report back progress later.
    Goodluck Optical, hope the reset work for you.
