Android 4.2.2 adb can't find devices

Question

With the new update to 4.2.2 to my Galaxy Nexus and Nexus 7, I can\'t find both my devices under adb.

These are the steps I took:

• Updated to 4

Answer 1

Here is what I did (Galaxy S4 4.2.2):

• go to Settings => about this device => click several times on "Version number", that is to say something like "JDQ39.I9505XXBHYTGKDD" (not android version or anything else) ; here you will see that Google or Samsung have a lot of humour as you have to click until multiple times until having a toast displaying "You are at few clicks from being a developer" ; after something like 10 clicks, you have a toast "You are a developer"

• Go "Development options" (in the "More" tab (rigjt tab of settings menu)) ; be sure that "USB debugging" is checked.

And it works ! Eclipse can see your S4(or any other device) 4.2.2 !
