Luckfox Lyra Ultra W armbian doesn't load

[Malay]

Hello everyone! I need help.
I was very happy to learn that Armbian support is now available for the Luckfox Lyra Ultra W!

https://blog.armbian.com/github-highlights-5/

This board has 8GB of EMCC memory and the firmware needs to be loaded onto this EMCC.

I went to this page in this mini guide

https://github.com/armbian/build/pull/8862?ref=blog.armbian.com

where is the author @vidplace7  clearly indicates how to correctly compile and install the firmware

./compile.sh BOARD=luckfox-lyra-ultra-w BRANCH=vendor KERNEL_CONFIGURE=no DEB_COMPRESS=xz KERNEL_BTF=yes INSTALL_ARMBIAN_FIRMWARE=no BUILD_DESKTOP=no BUILD_MINIMAL=yes RELEASE=trixie
Boot from emmc working (write to 0x0 with rkdevtool as the generated image includes the "loader")
Shell works over UART0
AIC8800DC WiFi works
Ethernet works

I compiled the Armbian-unofficial_25.11.0-trunk_Luckfox-lyra-ultra-w_trixie_vendor_6.1.115_minimal.img firmware without any problems and ran the RKDevTool_Release_v2.96 program.

I pressed the boot button on the device and the program RKDevTool displayed a message that the Loader device was found.

I checked item 2, selected emcc, the address was 0X0000000, and selected the image to flash: Armbian-unofficial_25.11.0-trunk_Luckfox-lyra-ultra-w_trixie_vendor_6.1.115_minimal.img.
I pressed RUN.

The flashing completed successfully.
The device rebooted, and the red LED lit up for 30 seconds, then went out—and that was it. The device no longer responded and wouldn't boot. If I pressed the BOOT button afterwards, the device didn't respond and didn't enter LOADER mode.
The only way to restore the device is to short two points on the rear panel and apply power. The device will be detected in RKDevTool in Maskrom mode, and you can load the factory firmware.

Unfortunately, I don't know how to contact the author @vidplace7  - https://github.com/armbian/linux-rockchip/pull/418

Please tell me what I did wrong? And why does the device become bricked after reflashing? I really want to install a normal system on it!
