Afaik you can start the initramfs image to get into openwrt itself and follow install like described in their wiki
https://openwrt.org/toh/sinovoip/bananapi_bpi_r3_mini#installation
Have only found openwrt boot for r4 but r3 should be similar
dumpimage -l openwrt-24.10.0-mediatek-filogic-bananapi_bpi-r4-initramfs-recovery.itb
tftpboot 0x50000000 openwrt-mediatek-filogic-bananapi_bpi-r4-initramfs-recovery.itb
bootm 0x50000000#config-mt7988a-bananapi-bpi-r4#mt7988a-bananapi-bpi-r4-sd
maybe you do not need the first command for r3mini, as there are imho no additional overlays
so only loading the initramfs itb and the boot it without passing overlay (skip from #, only address)
and of course use āfatload usb 0:1 ā¦ā instead of tftpboot 
Im stuck in here as well 
what should be the command
bootm 0x50000000#config-mt7988a-bananapi-bpi-r4#mt7988a-bananapi-bpi-r4-sd
for my R3_Mini ?
Usage:
fatls <interface> [<dev[:part]>] [directory]
- list files from 'dev' on 'interface' in a 'directory'
BPI-R3M> fatload usb 0:1 0x50000000 openwrt-24.10.0-mediatek-filogic-bananapi_bpi-r3-mini-initramfs-recovery.itb

## Loading kernel from FIT Image at 50000000 ...

Maybe there is some specific step-by-step instructions, with all the commands typical for R3_Mini? Then it would be easier for me, I didnāt think it was that complicated, and I still have to start the Quectel_Rm520 modem on this R3_Mini 
Regards and sorry for my lack of knowledge, but I really want to start this router.
just try
bootm 0x50000000
here, imho no config/overlay name required on r3mini
thank You so much 
It started working, now I will try to upgrade nand/mmc to version 24
What is the next step? i Will try this, from this page - but problem is not solvedā¦ https://openwrt.org/toh/sinovoip/bananapi_bpi_r3_mini#supported_versions
from this as well https://wiki.banana-pi.org/Getting_Started_with_BPI-R3_MINI

I wonder about immortalwrtā¦i thought you use openwrtā¦you should not mix images and instructions as they may vary.
But after flashing all, it should boot so just type ārebootā.
