    First of all, I'm not exactly a BIOS specialist, but so far I haven't had any problems either.
    Since no one has answered anything, may I ask - do you use Bitlocker or some other encryption on your system and did you turn it off before the BIOS update started? If you are using and did not switch off or at least did not switch to suspended mode, maybe you could try again and do it.
    Although newer so-called API systems should also do this automatically, there have been situations where this automatic system does not work as it should.

    Problem solved.

    I couldn't make it work through a USB stick with crisis recovery or similar.

    So, I decided to buy the CH341A recorder and flash the bios directly. In case anyone else experiences this issue on this relatively new laptop:
    1 - The chip on my board is W74M12JWSIQ, this chip works with 1.8v, to avoid burning the chip with the flash programmer, buy the CH341A programmer with the 1.8v adapter. On this board it was also possible to use the tweezers (alligator clip) directly on the board, so there was no need to remove the chip from the motherboard;
    2 - Download the neoprogrammer program (I used version 2.2.0.10);
    3 - As for the BIOS file, I used the backup file that the program generated before messing up my motherboard. The backup file is located at C:\Drivers\Flash\(folder with timestamp)\BIOSROM.BKP and is 16MB in size;
    4 - To avoid a possible component failure, before starting the procedure, I removed (disconnected) the following components from the motherboard: laptop battery, CMOS battery, NVMe card, sata SSD, network interface;
    5 - The W74M12JWS chip is a winbond W25Q128 series chip with an additional write protection feature, so when you open the neoprogrammer you must click the unlock button before doing any procedure;
    6 - Install the programmer drivers before executing the procedure;
    7 - When I open the neoprogrammer program, the W74M12 chip will be detected is the W25Q128FW, it worked perfectly for me on this chip;
    8 - To record the bios, with the neoprogrammer open, just select a functional bios file, click on the UNLOCK button, click on clean (zero) the chip, then click on record.

    Here's the tip for those who are going through this.

    Unfortunately I wasn't lucky enough to make it work via recovery, so here's a method that really worked on this model.

    MODEL: Lenovo 15ALC6 Type 82MF Board NM-D521 (Brazilian model)
