[Recovery Filename] Lenovo L340-15IWL Laptop

[mrhamed]

I have same issue with my Lenovo L340-15IWL Laptop but I didn't flash wrong, I used the https://download.lenovo.com/consumer/mobiles/atcn37ww.exe legal officially provided file and finally bricked, only showing black-screen with reboot continuously and a beep  


I extract BIOS image by awesome guide: https://github.com/liho98/lenovo-bios-logo-extraction-guide 

Also uploaded:

16MB BIOS binary here: https://clicknupload.co/3syvwddb7hu5
officially BIOS updater platform.ini file: https://clicknupload.co/wb1wzuzi3725

I used PhoenixTool.v2.73 to get correct bios filename for recovery:
status is: EFI/Insyde bios
filename: I don't get 
and finally the info message: "Header (INSYDEH2O BIOS    ACPI) (x1) Pubkey (x1)"

How find correct bios filename for recovery?

I bought this laptop yesterday

Hi
ATCrisis.fd

How you find this filename?

It does not works

Steps: 
1. Get an empty pen drive.
2. Open Command Prompt (as Administrator).
3. Type: "Diskpart" (Without the commas; this is for all commands)
4. Note the number of the USB drive by typing: "List Disk"
5. Type: "Select Disk X" (Substitute Disk X with the number of your own USB disk. Be careful)
6. Type: "Clean" (This will wipe the pen drive so make sure you don't have any information you want to keep on it).
7. Type: "Create partition primary size=128" (This will create a 128MB partition on your pen drive)
8. Type: "Format fs=fat32 label=CD_Crisis"
9. Type: "Assign" and exit "Diskpart"
10. Put BIOS file to pen drive neamed: CD_Crisis.bin
11. Disconnect AC power.
12. Put pen drive in the USB 2.0 slot by the power socket.
13. Press and hold Fn + R keys
14. Plug in the AC power 
15. Press power button. (because I hold Fn + R keys an orange light as side power connector blinking 5-6 times)
16. Pen drive in the USB 2.0 light blinking 2-3 times
17. Not success and reboot loop occur
 
It seem:

• BIOS file name is not correct, so bios recovery (Fn + R) cant found it. 
  
  
• or FAT32 file system can't load at this moment.
  
  
• or disconnect your CMOS battery is mandatory ( I didn't that because I think the recover process happen: Fn + R keys an orange light as side power connector blinking 5-6 times)
  

 
Can anybody Help me please?
