Xiaomi R4/R3G - Back to stock after Breed

So, I have a Mi Router 4, which is very close to R3G routers (same SoC, Nand flash). I flashed Breed Bootloader into it, but now, I want to go back to the stock firmware. Since replacing the bootloader with UBoot is too risky (I got a backup of the bootloader partition), what else can I do? Thanks.

İf you have dump of your router, in breed you can go to full dump section and uncheck all there squares. Then select dump and flash it.

Note: İts risky! İf your router will be bricked, the only way to recover it will be spi programmer. And İ have tried it in my mi 3c router.
