Is to wait for updates and do root.
I updated my OT-997D with the One Touch Upgrade Tool to the latest official ROM (vB5Y-0). But I certainly lost the root after the upgrade. The problem is that I could not root it again with the previously used method ('Root_with_recovery_by_bin4ry').
Could someone help me? Which method/tool should I use to root my phone again?
Thanks in advance!
