Unlock pattern has been used too many times on this android device and we don't have username and password. Most probably USB debugging might also be disabled. I can reset
wipe data/factory reset from recovery mode, but I want to backup contacts and messages before I do that. Because we don't have username and password, so contacts can't be recovered even if it is synced to Google account (which I think won't be anyway). Only option I have is
apply update from sdcard in recovery mode.
So is there any way to write some update script to copy the contacts data file to sdcard and then run it from update.zip?
Or if I can reboot the phone in USB debugging mode through update script as it happens after flashing some kernels?
Or if I can install an APK through update script?
Other details as below (in case if it matters)
