Nexus 7 (2012) destroyed by system update. Should I root it?

[uberman]

Lollipop Android system update froze my Nexus 7 (2012) last month. I've been waiting for the news of others experiences because I was an early updater. Yes, others were burned too. Any action on the previously excellent tablet takes two minutes or so. Log onto wi-fi and click a few times to check email is now well over 30 minutes. I thought a complete reset would fix it, but the new OS is now installed so it will revert back to Lollipop after the reset. It appears as though the fix is to flash the image of Kit-Kat to restore it.
Since flashing the image can produce a bricked device, I was thinking that I should simply root it.
Should I root it? I have'nt rooted before so it would be my first time.
I also own 2 Samsung Tab 3 10 inch tablets. Those will have to be rooted soon because it was decided that you couldn't manipulate files on the sd card. The only way for the user and some programs to use programs on the sd card of the Samsung Tab 3 10 inch is to root or to shut down the tablet, remove the sd card and work with the isolated card files with a computer.

My question here is to repair the Nexus 7, since the repair can be dangerous, should I root it since the risks would be equal?

You have a Nexus device, you would have to go out of your kill it. Also, what do you aim to fix on this by rooting it? That is sort of irrelevant to this.

You can try wiping just the cache partition which wont nuke your user settings, but if that doesn't help, I would do a full factory reset. The factory reset in the stock recovery is going to clear out userdata and cache filesystems but it does not impact the install OS, so you wont have to re-update in other words.

If that does not sort it for you, you can always flash this if you cannot fix it doing the above: https://dl.google.com/dl/android/aosp/nakasi-lrx22g-factory-2291c36b.tgz

That is the stock 5.0.2 lollipop build for your device. I have used it on grouper and it's not slow, certainly not as slow as your OP describes. That tablet has awful flash memory and its slow in general, but there should not be that kind of difference between KK and LP like you described.

If you definitely dont want lollipop, flash the 4.4.4 kitkat build back: https://dl.google.com/dl/android/aosp/nakasi-ktu84p-factory-76acdbe9.tgz

These downloads assume you are using the wifi version of the nexus 7 2012, if you have the mobile data version, grab those from here: https://developers.google.com/android/nexus/images

Instructions are in the file or on their site, this is a completely common and safe thing to flash, as I said you really cannot damage a Nexus unless you're being reckless on purpose. If you need help with anything lmk

the original lollipop update reduced mine to a crawl. I had to reinstall kitkat.

5.02 works properly tho.
