Lenovo Slim 7 14IRP8 bios

[FEDILE]

Hello, good day. My name is Federico. When I tried to update the BIOS on my Lenovo Slim 7 notebook, I got an error, and now the screen is black and it won't boot. After waiting, the screen appears saying "Recovery ROM part?" with two options, but neither works. I've included the model and serial number. Can I recover the BIOS from a USB drive? What are the steps? Thanks!

post the contents of the bios chip even if it is corrupted..

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

Refer to these guides:

1. Follow step 1 to format the USB drive to FAT32 with GPT partition table (be careful on this step, you may select the wrong HDD/SSD on diskpart)

1- Prepare USB Flash Drive

• Connect an empty USB Flash Drive to your PC (we will format it; all data will be lost)
• Open Command [prompt](CMD) as Administrator

• Type the following commands
  • Diskpart
  • List Disk
  • Select Disk # (Replace # with the number corresponding to your Flash Drive)
  • Clean (You may repeat this command until it's successfully executed)
  • Convert GPT
  • Create Partition Primary
  • Format fs=FAT32 Label=BHCrisis
  • Assign
  • Exit
  • Exit

* Label doesn't seem to be important, just the GPT partition table and FAT32 file system
* If possible use a USB drive less than 32GB

2. Copy LGCN.bin (attached, version LGCN36WW) to the root directory of the newly formatted USB drive

Continue with the next guide: https://github.com/nonkerdoob/Smokel...BIOS_CRISIS.md
3. Do step 7 of the second guide

7. Flash the BIOS

The Beep is damn loud and will last for 8-10min, so don't do this at night

If you have self healing problem is suggested also to remove the SSD, (The Self Healing File is on SSD, so removing it will not trigger the process again after the flash)

• Remove the Power plug
• Make sure that le laptop is off, pressing the power button for > 30 sec
• Plug the USB
• Press and keep pressed FN + R
• Plug the charger
• Press the power button
• The led near the Power connector will start blinking
• Keep FN + R pressed until the computer starts Beeping, can take 2-5 min, don't give up early, once start beeping can release the key, after a couple of beeps
• wait for it to finish, will reboot automatically when done
