Where can I find BIOS updates for a Lenovo laptop?

Question

Iron

Good afternoon. The problem is the following. After updating the BIOS version on a Lenovo Ideapad 110-15IBR laptop, the Ethernet adapter completely refused to work, the network card is shorter. It is not in the Windows Device Manager, nor in the output of the lspci command in Debian/Ubuntu/Centos, nor in the list of devices for booting via PXE in the BIOS.
I contacted the Lenovo hotline - they said we can’t help you, take it to a service center. And they added that this is not a warranty case anyway, since the warranty does not cover operating systems and (ATTENTION!!!) BIOS. They threw a link at me with a list of SCs and ended the conversation. I called several SCs in my own and neighboring cities (authorized SCs), where I heard that naturally this is paid and no one gives guarantees for the restoration of working capacity. Therefore, I appeal to the community, maybe someone has a BIOS update file for such a laptop lying around. My current version is 1GCN25WW . Version numbering is based on the last two digits. I need any, under the 25th version. If you need details about the laptop itself - I will provide any.
Thanks in advance.

there was a similar trouble with the g505 laptop, they updated the bios from the site and the vidyuha r5m230 discrete went out, the support said bring it to the service, you can’t understand what the bios is on their site, it was running version 2.04 and on beech native 3.00 under warranty the mother changed, then a native was found bios 3 00 on the Chinese site, I think yours can also be found PS In general, lenovo somehow does not care about customers
