ok first thing first here is a link the contains 4 different firmware for D3, mixed between bitmain and blissz , try each and everyone of them

* please scan for virus before you download, just to be safe.

-------------------------------------------

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

Code:
cd /www/pages/cgi-bin
    > hit enter

like this

then type this

Code:
vi upgrade.cgi

you will get something like this

but yours will be different, there will be something like

Code:
If sign *** signature not found

else sh runme.sh

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.

and if you speak russian you can visit the website > the solutation i am propsoing  is actually taken from this Russian website

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.

--------------

let us know how it goes.



Hello mikeywith, I hope you have spent a happy Christmas, I inform you that I have done so far.

First, I tried testing with the frimware that I had and as expected by me, they did not work, in fact some like the "NoFee" had already tested them before.

-------------------------------------------------

Given this, I started with the program of PuTTY with my IP and I made step by step what you indicated to me,
 - Loging, placing the password
 
Code:
cd /www/pages/cgi-bin
 
Code:
vi upgrade.cgi
(So far everything went the same as the images you placed)
 and I had this result:

Code:
login as: root
root@192.168.0.6's password:
root@antMiner:~# cd /www/pages/cgi-bin
root@antMiner:/www/pages/cgi-bin# vi upgrade.cgi
#!/bin/sh -e

# POST upload format:
# Content-Disposition: form-data; name="file1"; filename="..."^M
# Content-Type: application/octet-stream^M
# file contents
# file contents
# file contents

file=/tmp/$$

trap atexit 0

atexit() {
        rm -rf $file
        #umount $file.boot 2>/dev/null || true
        #rmdir $file.boot 2>/dev/null || true
        sync
        if [ ! $ok ]; then
            print "

System upgrade failed

"
        fi
}

- upgrade.cgi 1/219 0%

I leave the code so I wait for the next step and how to modify the file since I am not an expert in programming (I dedicate myself more to the Hardware part  Grin)
