How to clear cache partion on Nexus 9

STORY

Is your Nexus 9 get bit too slow over time?
Probably your problem is with fact that you ran too much on the tablet because  HTC screwed up badly as they decided to sadly have a crap idea to put on 2 GB RAM in this otherwise amazing tablet. There is nothing that you can do about it.
However sometimes Android get very slow due mess with the cache. In this case, there is a solution.
Did you search on the internet and found a few solutions to this problem? Well.. many of them are correct as it depends on the version of Android and bootloader.

This one will work on Nexus 9 with Android 7.1.1 and quite a decent version of bootloader.



SOLUTION 

  1. Charge battery to 40% (or to ensure that it will have enough battery for 30 minutes).
  2. Power off the tablet.
  3. Press and HOLD power button and volume down button for around 10 seconds.
  4. When the menu appears. Select Recovery (It is usually 2 or 3 position).
  5. When you will see lying down android with a red triangle (with the message "no command"), press and HOLD power button and press volume up button twice slowly.
  6. Then select wipe cache partition.
  7. Press Yes.
  8. Wait up to ...30 minutes (In my case it took 10 and 25 minutes, but it varies depends on the amount of crap on this partition.
  9. DONE.
