recently, my phone was dropped with an otterbox case and the digitizer cracked. allowing me to turn on the device and nothing more. I am able to get onto a PC and install ADB and SDK manager on my PC to help speed up the process but from there, I only know how to backup everything. something on the lines of adb -backupall I really only am looking to restore contacts and a few other personal data. THE PHONE IS ROOTED. but again, i simply cannot do anything with the screen being broke. any help with adb to restore contacts would become a huge relief as i did not sync everything with gmail. also, is this something covered under the manufacturer warranty? Thanks!
