[REQUEST] Lenovo B50-70 (9DCNxxWW) BIOS Unlock

[Esmat]

Dear
I hope this email finds you well. I am writing to request your assistance regarding an issue with my Lenovo B50 device (Serial Number: CB32698332).

Issue Details:
1. Current BIOS Version:*9DCN21WW (V2.02)

2. Problem:
- When attempting to update the BIOS using the official Lenovo website’s update tool, the device restarts but displays a "Failed" message.

- My system runs *Windows 10 (64-bit), and I followed all instructions (running as administrator, enabling BIOS flash, etc.).

- Boot Delay:* The device shows a black screen for 10+ minutes*before Windows starts, even though the hardware (HDD, RAM, etc.) works fine on another device. I’ve tried discharging static electricity and resetting the CMOS battery.

Request:
I kindly ask for your support in:
- Providing a working BIOS update solution or an alternative method.
- Troubleshooting the boot delay issue if unrelated to the BIOS.

I appreciate your prompt attention to this matter. Please let me know if you require further details.

Best regards,

Hi
Using the Universal BIOS Backup ToolKit 2.0 for your laptop model is not desirable...use BACKUP_Tools19 or fpt only
