[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,
