Error after error in booting and in recovery mood My tablet brand is ASUS and its android's version is 5.0.1. It shows many error  likes Unfortunately com.android.setings has stopped, Unfortunately UI has stopped, Unfortunately Launcher has stopped frequently. Sometimes when I restart it, it doesn't show my desktop. Also its reset to factory doesn't works properly (it just reset the time of tablet).

I have cleared the cache and data of setting but errors persists.

So I decided to recover my android. After holding power button and + volume, I chose recover option and it got to the recovery page. after 5-7 seconds the error appeared with death android icon and just the word "error" as its caption. 


  How to recover my android? what files I need? What is the adb?


Please note that my (android of) tablet is not longer supported by ASUS Inc. Also I have reset my android to factory setting 1 month ago successfully.
I have downloaded My tablet driver from ASUS website and then the following ADB command in boot menu resolved the problem completely. (notice that it removes user data I think!)

adb sideload &lt;filename&gt;
