 If you’ve [[/products/sbc/vim3/development/linux/build-ubuntu| built the image with Fenix]], replace the file ''archives/logo/png/logo.png'' to change the logo.
 ===== Android =====
+Because RK merged the logo partition with the system partition into a single super partition after Android 10, there is no logo partition available to dynamically modify the boot logo. This means that a complete firmware build is required to achieve this operation. Now, we have added a new custom partition to facilitate the dynamic update of the logo.
+==== Logo Format ====
+<WRAP info >
+  *Where is original logo file
+Logo file is stored in the kernel-6.1/logo.bmp directory in android code.
+  *BMP format, should be:
+    *16bit RGB565 BMP format
+  *Resolution <= 1080P (1920 * 1080)
+</WRAP>
+==== Kernel Logo ====
+We use the adb command to push the prepared logo.bmp to the motherboard path /vendor/custom and then restart the device.
+```shell
+$ adb root
+restarting adbd as root
+$ adb remount
+AVB verification is disabled, disabling verity state may have no effect
+Remounted /system as RW
+Remounted /vendor as RW
+Remounted /odm as RW
+Remounted /system_dlkm as RW
+Remounted /system_ext as RW
+Remounted /vendor_dlkm as RW
+Remounted /odm_dlkm as RW
+Remounted /product as RW
+Remount succeeded
+$ adb push logo.bmp /vendor/custom
+logo.bmp: 1 file pushed, 0 skipped. 655.0 MB/s (4147272 bytes in 0.006s)
+```
+==== Updage the logo by upgrate whole firmware ====
+) replace kernel-6.1/logo.bmp bmp file
+) build upgrate package
+```shell
+$ cd PATH_YOUR_PROJECT
+$ source build/envsetup.sh && lunch kedge2-userdebug
+$ ./build.sh -UCKAu
+```
+) Burn upgrate package update.img to your device you can refer How To Upgrate ,restart then you can see the new boot logo
