I have bricked my redmi ax6000 router it seems most of the partitions are overwritten. I have a textual copy of my bdata.bin (mdt2 backup) and factory (wifi data) what can recover the essential data,but i need a binary basic version can anyone give me a copy of the bdata.bin (256kb) binary data as a routers base . router is redmi ax6000 chinees version modified to openwrt
im not aware of different versions but am in need of an copy to be used as base for a new bdata

Thanks for all help in advance

If you EVER installed official OpenWrt you should have a binary, 1:1 copy of it on your disk

I don't understand what's a "textual" vs "binary" copy...

but with bdata and factory, you should be able to unbrick using mtk_uartboot. Grab the generic mediatek BL2 (preloader) file and the device-specific FIP file. The only partition you'll be missing is nvram which isn't used with the u-boot layout.

These instructions are for a different device but the steps are similar.

All this assumes you have UART access.

mtd2 (bdata) containc mac addresses and other oem parameters.

Have you tried recovering using mtk_uartboot?

I'm pretty certain you have a backup of bdata and factory if you followed the instructions. If not, then please elaborate on what you've done so we can help. What will you do with someone else's bdata backup?

Perhaps someone can help you in the developer thread dedicated to the device.

Nott me asking to reco:ver OEM firmware installation.

If you're saying you have a text hexdump of the file, hexdump can run in reverse mode to create a binary file.
