+## Flash guide using Raspberry Pi and clip
+
+```Note: This is a rectified generated guide for reference```
+
+### Tools and Materials Required
+
+Hardware:
+- Raspberry Pi (any model with GPIO pins)
+- SOIC/pomona clip (compatible with your EEPROM)
+- Connecting wires or a breadboard
+- Optional, Resistors (for pull-ups if needed, 4.7kΩ is common)
+
+Software:
+- Raspbian OS (or similar Linux distribution)
+- flashrom (for SPI-based EEPROMs)
+
+### Step 1: Prepare the Raspberry Pi
+- Install the OS:
+- Flash Raspberry Pi OS onto an SD card.
+- Boot up the RPi and configure it using sudo raspi-config.
+- Enable Interfaces, go to Interface Options in raspi-config and enable SPI (for SPI EEPROMs) 
+- Update the System, `sudo apt update && sudo apt upgrade -y`
+- Install Required Tools, `sudo apt install flashrom python3 python3-pip -y`
+
+### Step 2: Wiring the SOIC Clip
+
+- Pin Mapping, match the SOIC clip pins to the EEPROM pins (refer to the datasheet for pinout).
+- Connect to Raspberry Pi: For SPI (e.g., 25 series):
+  - MISO → Pin 21 (GPIO 9);
+  - MOSI → Pin 19 (GPIO 10)
+  - CLK → Pin 23 (GPIO 11)
+  - CS → Pin 24 (GPIO 8)
+  - GND → Pin 6
+  - VCC → Pin 1 (3.3V)
+- Double-Check Connections, ensure the SOIC clip aligns correctly with the chip pins.
+
+### Step 3: Test the Connection
+
+- For SPI EEPROMs, use `flashrom` to detect the chip `sudo flashrom -p linux_spi:dev=/dev/spidev0.0`
+- If detected, note the chip model.
+
+### Step 4: Backup the EEPROM
+
+- For SPI EEPROMs, `sudo flashrom -p linux_spi:dev=/dev/spidev0.0 -r backup_rom.bin`, this reads the EEPROM contents into backup.bin.
+
+### Step 5: Flash New Firmware
+
+- For SPI EEPROMs, `sudo flashrom -p linux_spi:dev=/dev/spidev0.0 -w new_rom.bin`
+
+### Step 6: Verify the Flashing
+
+- Read the EEPROM Again, Dump the EEPROM content after writing, `sudo flashrom -p linux_spi:dev=/dev/spidev0.0 -r flashed_rom.bin`
+- Compare the new dump with the original firmware, use diff to verify `diff flashed_rom.bin new_rom.bin`
+- If no differences are found, flashing is successful.
+
+### Step 7: Clean Up
+
+- Disconnect the SOIC clip.
+- Restore any configurations on the Raspberry Pi.
+- Safely store backups of the original firmware.

+
+### Instructions
+Flash the USB method as listed below: 
+
+0) TAKE OUT THE BATTERY FROM YOUR LAPTOP!
+1) Plug in your charger, enter the BIOS, change 2 values.
+   a) Setup->Boot->UEFI Settings->UEFI Boot->Enabled
+   b) Setup->Security->Secure Boot->Disabled (If you can not find this then you don't need to change it)
+2) Unplug all your drives including any SSD's and HDD's
+3) Put the EFI folder into your FAT32 formatted USB Flash Disk, now put the bios file into the EFI->Boot folder and boot your laptop through the USB.
+4) Wait for startup.nsh to execute, and then type "meset", press enter.
+5) Your laptop will auto reboot and the fan will run at high speed, THIS IS NORMAL, boot to the USB Flash Disk again.
+6) Wait for startup.nsh to execute, and then type "`fpt -d backup.bin`", press enter to backup your bios.
+7) Now type "`fpt -f BIOS.bin -rewrite -y`", press enter to flash new the cannon lake bios .
+8) Wait for the flash to finish (you will see color text "(...) successful (...)" info printed on screen by fpt).
+9) Just unplug power cord, without battery it will hard shut off computer.
+10) Then insert battery again, plug in charger
+11) Turn computer on.
+
+### Notes:
+1) After executing step 4 (MESET) and the fans ramp up you may have to wait a couple minutes for the screen to come back. don't freak out, just give it some time.
+2) Also after it finishes flashing (step 8) the first boot might take 5 minutes (probably not the whole 5 minutes, but leave it and let it train the memory? Not sure what it's doing, but 9/10 times it works great, if you leave it booting). Anything over 15 minutes maybe try a single stick of 2133 or 2400 ram and see if it will boot that way. 
+3) If something goes wrong you can opt to flash with rpi and a clip anyway
+4) No warranties, support or anything is included in this.
