      Using HxD search for the text: LENV .The DMI is crypted,there`s 2 LENV areas to copy,use the offsets in the picture, copy from your backup and paste-insert into the same offsets in the new bios.

          It took me several attempts, but in the end by copying offset 234000 to 235FFF, I did it!

          Thanks a lot SMDFlea

                  Hi everyone,

                  I have a lenovo ideapad 310-15isk after a restart before or on the lenovo logo I held the power button to power it off. After I tried to power it on I had black screen, cpu fan working the laptops works for about w0 secs and then restarts automatically and the whole process repeats. I tested many ways and at last I found that the problem is the bios. I want to flash the bios using a USB flash drive.I have three problems and I really apreciate your help.
                  1. which file to use for ideapad 310-15isk A751 Rev 1.
                  2. what should be the exact name of the .bin file so that the computer can read the flash and the bin file when I connect the USB flash drive?
                  3. what keys should I hold before powering the laptop? (I hear fn+R, but I am not sure whther it works for this model of laptop).
                  If there is any other procedure I should follow,please tell me.


                  thank you so much for your time.
                  Hamid

                      Lenovo IdeaPad 330 15-AST 81D6 BIOS Recovery
                      by jendkkd jeje
                      So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.

                      I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...

                      BIOS file (.BIN) for semi-Bricked IdeaPad 3-14ALC6
                      by Fr33man
                      Hello everyone,

                      I soft BRICKED my Lenovo IdeaPad laptop (black screen with led lights on, responsive keyboard backlight, fans spinning) after messing about with a Github tool called Smokeless. I am now attempting to reflash the bios through USB, but I am not sure if I extracted the correct BIOS ROM file to flash, and I also could not find the correct file name to rename it to (GLCrisis.bin, GLCN.bin, Currom.bin??). In addition to attempting to reflash the Bios with a USB, I have also performed the following activities:
                      *Novo button power on
                      *Disconnected internal battery...

                      BIOS Backup / extract 16MB .bin - Lenovo ThinkBook 13s G3 ACN - 20YA0005GE
                      by DiddiAb
                      Recently I used the official Lenovo bios updater software on my ThinkBook 13s G3 ACN (20YA0005GE). The updating process failed and I got a black screen after powering the device. Of course I did not make an own backup before using the Lenovo bios updater.

                      I bought a CH341A programmer and was able to make a connection to the chip while it is still soldered on board. But I did not realise that the chip was a 16MB size and selected the wrong size (8Mbit / 1 MByte) before reading the content of my chip. So the dump I did before erasing the chip is only 1MByte big. I fear that I lost...

                      Hello,

                      At first i tried to Backup the BIOS with tools direcly from Windows(normaly i am a Linux user). But no full success because not every part of the bios was readable. So i bought a modified CH341a for a Backup.
