  1. Hi,
    When you say “Copy the zip file and place it in your Internal Memory”, what do you mean?
    Phone internal memory
    Phone SD card.

    As next to next step you have mentioned “Select Apply Update from SD Card”
    It’s bit confusing.


    1. I did meant Internal Memory. Copy the zip in Internal Memory. In recovery mode if you select Apply update from SD Card, it will be followed by screen which will show both internal and external memory. Select Internal and proceed with flashing.

  2. If I unlock the bootloader, root and install a custom ROM, these instructions will make me able again to receive Asus software updates?

  3. This firmware is ww. If not, where do I find the firmware ww. My asus max came with a custom ROM and I can not do the updates.

  4. Im on custom rom RRN, I want to downgrade to Stock lollipop, can I flash this directly on TWRP in RRN Rom

    Thanks in advance
