    Okay. I got the MiniDos.sys file copied to the pendrive along with the JE40219.wph & pflash.exe.
    Now shall i start the laptop normally and just leave it running for it to work?
    Can i keep all versions also on the USB (
    JE40219.wph, BIOS.wph, JE40219.fd and BIOS.fd)?

    You must insert the pendrive, press & hold FN+ESC keys, then turn the machine on just like before. You can try to keep all versions on the pendrive to save time but the sparse documentation we have suggests only one version at a time.

    I tried all possible versions, still same results. The USB LED flashes for 4 intermittent times (every time 2-3 seconds) but never shows real activity. I'm starting to lose hope :/
    I'm not sure what might be the problem anymore.

    I know this is frustrating but now you must try the same things with renaming the JE40219.rom file.
