-### Flash Firmware
+#### 1. Prepare the microSD Card for Flashing with These Parameters
 
-⚠️ Make sure the microSD card has been prepared using the instructions found [here](https://github.com/bassamanator/Sovol-SV06-firmware#1-prepare-the-microsd-card-for-flashing-with-these-parameters).
+- Size: `16GB` maximum.
+- File system: `FAT32`.
+- Allocation unit size: `4096 bytes`.
+- Must not contain any files _except_ the firmware file.
 
-1. Rename whatever firmware file you're using to `firmware.bin`. ⚠️ If the file is not renamed, the bootloader will not be updated properly.
-2. Copy `firmware.bin` to the root directory of the microSD card.
-3. Power off the printer.
-4. Insert the microSD card.
-5. Power on the printer.
-6. After a few seconds, the skr-mini-E3-V3.0 should be flashed, but wait a full minute just to be sure.
-7. You can confirm that the flash was successful, by running `ls -l /dev/serial/by-id/` or `ls -l /dev/serial/by-path/`. If the flash was successful, you'll see something like the following:

+#### 2. Flashing Procedure
+
+1. Disconnect any USB cables that might be connected to the motherboard.
+2. Copy `firmware.bin` to the microSD card.
+3. Make sure the printer is off.
+4. Insert the microSD card into printer.
+5. Turn on the printer and wait a minute (usually takes 10 seconds).
+6. Turn off the printer and remove the microSD.

-## Firmware Precompiled by BIGTREETECH
-- [firmware-USB.bin](./firmware-USB.bin). Connect the SKR-Mini to the Raspberry Pi via USB connection.
-- [firmware-USART2.bin](./firmware-USART2.bin). Use TFT port USART2 to communicate with raspberry pi. Connect the UART-TX of raspberry pi with the USART-RX2 of motherboard and connect the UART-RX of raspberry pi with the USART-TX2 of motherboard directly to communicate normally.
