    The guide is no different than the original guide that was created by the developer. What we do is redistribute the guide to a wider audience.

    I’m sorry the guide wasn’t useful for you.

    I’ve never read such a crappy guide. This is a guide for burning time and distroing venues

    I have recently bought one of these, and the owner forgot to remove his google account before he reset it. Does the above enable me to bypass the FRP? What mode should I put the venue in before I root it? Do I need to use an OTG cable? Thanks for your help. I have tried the above and with the venue in recovery mode, FRP lock enaled, I could read and load data to the SD card on the device, but I couldn’t flash it, although I had the port set correctly.
    Thanks again
