    I'm happy for you. It's the one problem I couldn't fix. Largely because it was a work laptop. So I couldn't really go crazy fixing it. It got fixed though. They took it to a professional.

    Hi there,

    can somebody help me finding the filename for my Ideapad 320-15IKB ?

    Tried several filename such as AA.fd BB.fd Bios.fd ATCrisis.fd but the recovery is still not working.

    Is there a Google Sheet where all found filenames are written down? Maybe this would help many of us.

    Can't believe this finally worked for me (Ideapad 720s 14ikb, uses InsydeH2O bios). Thought someone could save time using the same steps. Here is what I ultimately did:
    - Download latest bios (.exe) from lenovo
    - Download innoextract 1.8 (zip includes .exe) from github
    - Download 7zip
    - Create new folder and copy innoextract.exe and biosfilename.exe there, then on command line: innoextract biosfilename.exe
    - This creates a new folder, in which you will find similarly named BIOSFILENAME.exe. Extract that file with 7zip
    - Now, follow the steps of the posts in the first page of this thread: open extracted platform.ini file and look for PlatformName. In my case there were values for PlatformName1 and PlatformName2. Then copy extracted .ROM (could be .BIN or other format) file and make copy for each PlatformNameX.fileEnding (ROM, BIN...) as listed in the first page
    - Add all these renamed copies to your usb drive
    - Shut down bricked computer. Hold fn + r + power button for 15 seconds until fan spins, after that release power button, then release fn & r
    - Plug in usb drive and turn on the computer
    - After a few seconds, computer starts reading the usb drive and starts beeping (success).

    Let me know if this helped

    This worked for me with a bricked Lenovo Yoga 730-13IKB

    I did the following:

    - Download latest bios (.exe) from lenovo
    - Download innoextract 1.8 (zip includes .exe) from github
    - Download 7zip
    - Create new folder and copy innoextract.exe and biosfilename.exe there, then on command line: innoextract biosfilename.exe
    - This creates a new folder, in which you will find similarly named BIOSFILENAME.exe. Extract that file with 7zip [note that other software didn't work for this]
    - you will now have a bunch of files, one of which is named ***.rom
    - You now need to rename the file so that the computer will recognise it. I couldn't get a clear answer on what to call the file by looking in platform.ini or using andy's tool, but after trying a few options it worked with one of the following:
    AA.bin
    AAHW.bin
    BB.bin
    BBHW.bin
    BIOS.bin
    DLZP3.bin
    DLZP3X64.bin
    - So make a bunch of copies of the ***.rom file rename each to one of the names above and add all these renamed copies to your usb drive
    -Shut down bricked computer and disconnect power cable.
    -Plug usb drive in to bricked computer.
    - Hold fn + r plug in power cable.
    - press the power button (keeping fn + r held down)
    - After a few seconds, computer starts reading the usb drive and starts beeping (success).
    - release fn + r once the computer starts beeping.
    - wait until it stops beeping and shuts down.

    Finished!
