Still no root, but last I checked were at around 450 with kingroot. So I broke my screen wrestling the other night. Smashed the gorilla glass up good and even damaged the digitizer.I didn't want to pay for a repair. I have an old boost max n9520 with a corrupted data partition I picked up for $20 off a stranger, long story short the LCD screen and digitizer and the whole front half of the housing of the n9520 fit perfectly and functions perfectly with the boost max + n9521!! Although I can see a difference from the other screen, it beats having to use vysor and a laptop to use the device haha. Vysor rocks btw!
