+# Dump of bootloader V3.0.5
+
+This is the bootloader dumped from MKS TFT Controller V1.4. It is only suitable for TFTs with GD32F305VCT6 MCU.
+Do not use on any other TFT !!!
+
+
+## Usage
+
+Require an ST-link tool attached to the SWD port of your TFT Controller (should be soldered).
+
+#### Dump
+
+Execute the command `st-flash read bootloader.bin 0x08000000 0x7000`
+
+#### Flash

 1. The firmwares use the naming convention `MKS_TFT*_V*.*.*.x.bin`
 2. Any binary file for an MKS firmware (e.g. `MKS_TFT28_V4.0.27.x.bin`) **MUST** be renamed to `MKSTFT*.bin` (e.g. `MKSTFT28.bin`, `MKSTFT35.bin` etc.) in order it can be recognized and installed by the TFT
 
+For MKS TFTs **GigaDevice MCUs** (like the newest version of Genious Pro):
+
+1. rename the right binary (e.g. `MKS_GD_TFT28_V1_2-4.27.x.bin`) in `mkstft28evo.bin`
+2. create an empty `mkstft28.bin` file
+3. create two empty directories `mks_font` and `mks_pic`
