if everything fails then as i mentioned you need to modify the current firmware on your miner to force it to allow you a different firmware.

you will need to use a ssh tool like putty.

type the ip address of the miner in putty , keep port 22

* if message pop up > click Yes

username :root
password:admin

then you will be inside the miner.

copy paste this line

    > hit enter

like this



then type this


you will get something like this


but yours will be different, there will be something like


you need to copy paste the code for me here to modify it, if you don't understand programming.

if you do, then it would be easy, just remove the IF statment.

even if you don't understand russian, you can follow my directions and then look for the picture for the upgrade file, it's in english and could be exactly like yours, if it is, just follow the picture, if it is not, just paste the code here i will modifiy it for you.

also keep in mind the default upgrade file will be locked ,you cant modify, only view. you need to click 'I' to modify it.
