lenovo s145-15api, black screeen after BIOS update

[robertouplink]

hi guys!

can you help me? I have a problem with my lenovo s145-15api. I did a BIOS update but now the machine doesn't want to display an image. It won't start.
When I press the power button, it lights up and stays lit.

I tried to recover it by saving the bios.cap file on a flash drive, connected it to the notebook and pressed fn+b; fn+r but it didn't work.

Lenovo IdeaPas S145-14API
Model Name: 81V7
M0: PE9039C20132
MTM: 81V70004BR
S/N: PE05BNYP

If there is a way to do this recovery using a flash drive it would be better. But if necessary I have a ch341.

Thank you very much!

You must post in an existing thread.
You must provide the bios backup.
Sorry there's no lazy method tho dump the bios, so grab the programmer and read the rules.
