Xiaomi Mi Router R3G V1 Recovery Breed

hi, i have mi-R3G V1, i just installed keenetic on my router using breed bootloader, i did full backup and also did a stock bootloader mtd but the problem i didn't like keenetic os and wanted to change it, i have to flash full backup to return to stock, but i find that flash backup has 135 mb instead of 128 mb it wont flash because of the size, can anyone help or send me the full flash backup, thank you in advance
