Dear @eduardo010174
looking on BREED bootloader I see that the file size is only 89 kB.
https://breed.hackpascal.net/breed-mt7688-reset38.bin
Therefore the available address range of uboot should not get exceeded - and therefore other partitions should not be overwritten with BREED.
Moving partitions would only be needed if those would get overwritten when flashing BREED.
But I am not sure if I understood you correctly.
Could you please check the file linked above and see if partitions are overwritten?
Thanks!
