    versioon 1.15 has video bios update so u probably want older one. then update.
    however 1.11 shows
    1. Fixes when change display mode to 'dGPU only' mode in setup, save and exit will cause 5 more seconds and shutdown in DC mode. 2. Changes EC bios to V3.3 and fix the bios Crisis issue.

    which means u need to find out what crisis issue it is.

    1.11 in win shows .BIN while 1.08 shows .fd hmmmm
    try recovering with 1.08 with filename ZR7X64.fd

    i think 1.11 is good candidate for spi programmer as its .bin not .fd originaly in package.
    1.15 is also .fd

    bigger chip can use 1/2 the data and leaves rest blank.
    as long as the pins are same and voltage i same it should work.

    Can you use a flash programmer to backup whatever's currently on your chip(s) and upload them to a filesharing site?

    I may be able to convert BIOS files from Acer's site to the format they need to be in to be writeable with a flash programmer.
