    I followed all the steps: the LG Flash tool successfully establishes the connection with the phone, the verifications are done and the upgrading process begins. But, when the S/W upgrade reach 9%, the process stops and appears the message “Upgrade stopped due an error”. I tried to use all the different kdz’s (always only for the T-Mobile’s H811). Help please…

    The one step missing is the phone needs to be in USB Debug mode, or it won’t connect to the PC
