Maybe someone has a suitable version for EC (bid T70)? I've tried many files from this thread, so far without success.

Hello!
I wanted to post on the forum with a question about unlocking the BIOS, but during soldering, one of the EC ROM pins was torn off. The original EC ROM dump is permanently lost. I only have the original SPI ROM dump.

I replaced the original EC ROM GD25B256DYIG with a Winbond 25Q256JVEQ and flashed the dump from this thread. However, the laptop blinks 7 times and does not turn on.
I kindly ask for help in restoring the laptop’s functionality.
