    Default Frozen with Rainbow Pixels

    Hello,

    I received a Google Nexus 7 for last Christmas. I didn't have any issues up until today. The screen just froze and the screen turned all pixely that was rainbow. I was able to turn it off, and tried doing a repair, but it just froze and went back to that screen. Sometimes I can hold the power button and touch the screen and the normal screen pops up. I'm not able to do anything though because the screen is frozen. I recognized that it was in airplane mode. Any help would be appreciated. Thank you. This is what the screen looks like.

    Yikes! Try powering off by pressing and holding the Power button until it turns off. Then see if you can boot into Recovery Mode and wipe the cache partition: [GUIDE] Nexus 7 (2012 & 2013) Cache Partition Wipe

    I'm able to power it down, but once I try to turn it on, it freezes and then eventually I have press the power button to turn the screen on and it's that rainbow pixles.

    Does the screen look normal up until the point when it freezes (I mean, during boot you see the four balls and the Google text)?

    Are you saying that the screen freezes and then times out and goes dark, and when you short-press the Power button to turn the screen on it looks all garbled?

    Have you tried connecting it to your computer to see if it's behaving normally (despite the weird screen pattern)? If so, you may be able to reload the firmware.

    When I turn it on, the screen times out and goes dark, then when I short-press the Power button, the screen looks like that. I've connected to my computer and it seems to behave normally besides the screen.

    I've been trying to fix it, and I found that if I hold my finger down on the screen while I short-press the Power button it goes to the lock screen. I'm able to unlock it sometimes, but it freezes a little afterwards.

    Since the computer recognises it you should try reloading the stock firmware. You can try Nexus Root Toolkit (not just for rooting) or do it yourself:

    here - just
    - boot into Fastboot mode (with the device completely off, press-and-hold Volume Down + Power)
    - connect it to your computer
    - download Fastboot.exe from XDA
    - run "fastboot oem unlock" from a Command prompt (elevated to Administrator privilege) (this WILL wipe your device)
    - then extract the contents of the firmware download and run the "flash-all.bat" file
