You need to flash them again using a different SD-card , if the led lights don't blink then it's unlikely your miner is going to work, therefore it will not be request an IP address from the DHCP server, I don't have a technical explanation on how this problem happens, but sometimes an SD card just won't work well for a certain miner.

Avoid newer cards, use the older, smaller and slowest mini sd card you can find. Don't use SDXC and preferably not SDHC, the smaller the better, under 1g.

I could mention that an old SDHC reader isn't ever going to read an SDXC card, for example, but there is more to it.


Another reason is the way you are imaging the cards. DD under Linux is always the best way, as Windows and osx are too unreliable. In any case do a sync after dd before ejecting.

Yeah:

 sometimes a sony will work sometimes it won't
 sometimes a samsung will work sometimes it won't

I have a dell laptop  it does great imaging  I do almost all my  usb and sd cards with it.  Win10 is what I use.

I have multiple pc's and for some reason this laptop  is great to burn cards and sticks.


I was looking to burn a usb stick for a mobo bios I could not get any stick to work fired up the laptop  stick works fine when burned on the laptop.

I have work with computers since 1974.  Back then we used 3600 foot reels of tape ½ inch wide.

Sometimes a tape could not be read  we would move it from reel to reel to reel and 1 machine would read it.  Gear has been like this for year.

BAF  tapes were good on almost every reel to rell we had. It all changes yet stays the same.

This always happens mostly fake SD card won't work you need to get a better SD card it must be the authentic one.
If you make a program recovery with SD card and didn't work when trying to flash the miner it's because the program or image from the SD card is corrupted you need to repeat the procedure to make it work redownload everything, remake a program recovery again then reflash.

Also, check the SD card terminal under the control board it might be full of dirt and rust. Solution: cleans it with thinner(lacquer flo) then resolder the terminal.

There are some control board that you need to jumper 2 terminals to enable sd card flashing check the image under this guide below[/url].
