Try redumping the firmware again in Dosflash until you get the correct size. You can try doing it in the latest Jungle Flasher V0.1.70 beta (86). The methods should be the same as Dosflash (

When you dump, the firmware .bin file size should be 256KB (262,144 bytes). Kinda a weird problem you have.
By the way, make sure you do use the latest JungleFlasher when attempting to flash.
