    yoga x390 (x13 to confirme )nuvoton npce288/388 sv password removal guide with svod4

    before you start the procedure read the bios eeprom and save it you might need it at the end

    1do not power on your svod yet
    2plug you ribbon 30x0.5 to the left of the keyboard connector
    3test pin with testeur if it beep go to next stage
    4 open svod software select 1.8v
    5 now plug your svod
    6 select nuvoton
    7 plug charger on the board/laptop
    8 press read id
    9 select 256k
    10 read nuvoton
    11 save reading, now unplug the svod
    12 open HxD software and open your 256k file the one you just saved
    13look for offset line 36000
    14 select the all block for my case from 36010 to 36CE0 and delete it, this can change depend of the password, but the password area always start at 36000 for this EC
    15 now go back to the svod sotware and open the file you have modified, replug select 1.8v 256k size and flash it it will give you an error at the end of the flash, because the file is smaller than 256k, ignore it
    16 unplug the svod remove the keybord adapter/extender the laptop will not start if its stillconnected to the svod see picture and restart the laptop /motherboard, the laptop will restart once and the second time it will show a little dot on top left corner of the screen , wait few seconds and voilas the laptop is unlocked sometime for some reason you have to reflash the bios eeprom with the 32mb dump,not sure why

    i will join more pictures later , this method is working for l380x390 and probably for the x13 and other laptop having the same EC
    enjoy

        I do everything as in your instructions, but then I get the following message: 0177: Bad SVP data, stop POST task. And laptop turn OFF. Can you help me ?
