After hours and hours of complete frustration, despair and sheer hopelessness to the point of being convinced my ZTE Max was bricked for good—to my complete surprise, after pressing the power button for a silly amount of time (it seemed to be almost a minute—at least 45 secs) it came back to life. Like a freakin’ Creature From The Deep!. Yeay. No guarantee but it worked for me! Humbly Yours, Max PS: I don’t recall exactly to be fair, but the procedure also required holding the Power Buttons as well—for 20-30 seconds.
