Hi, everyone! After some attempts to recovery my router from softbrick as was described by some members in this thread, I'm here. I'll be glad to recieve some help! (It was the first <> time I'm trying to patch router, so...)
What I have: softbricked RD23, UART chip and completed all staff about putty/tftp from this thread.
Router startup error:
System halt on router startup

System halt!
I supposed that I damaged bootloader 
===
But using mtk_uartboot I still can load image to router:
p.s. I understood that mtk_uartboot is tool for load and execute binaries over UART, but have vague ideas what are the payload and fip payload that I have used:
mtk_uartboot -s COM8 --payload bl2-mt7981-bga-ddr3-ram.bin --aarch64 --fip openwrt-mediatek-filogic-xiaomi_mi-router-ax3000t-ubootmod-bl31-uboot.fip && putty.exe -serial COM8 -sercfg 115200,8,n,1,N
Windows shell log after rebooting router

Some info (I supposed it's the environment of .bin I have loaded tih mtk_uartboot?):
root@OpenWrt:~# cat /proc/cmdline
console=ttyS0,115200n8 console_msg_format=syslog root=/dev/fit0 rootwait
===
So, the answer is: how can I fix System halt (fix bootloader?) using tftp recovery? The method to just sysupgrade image loaded with WinSCP doesn't make any effort --- after reboot System Halt met
I will be very glad to resolve my problem (and help all faced the same issue)
