There have been some posts about loosing connections to the V9 miner.
Also some people have had issues with the new T9+
If you take a look here:
https://shop.bitmain.com/support.htm?pid=007201604120945219855QObfk20066C
You can get the downloads to burn a SD card to restore your firmware.
***The T9+ is not the same as the T9***
If you put the wrong firmware on you will probably own a paperweight.

Here are the files from the above posted link.

Which are needed on the SD Card?

If S2S4S5S7-img is one of the needed files and the V9 .tar is the other  is it a two step process?

That is burn the S2S4S5S7-img first then on another SD card run the .tar file   Huh?

or can you just put all the files on one SD card and let it run?


These two files from Tools and Instructions to Image SD card
 
DiskImager    Application  88 KB
 
S2S4S5S7-img   Disk Image File  512,000 KB

If you put a wrong firmware it can result of deadboot or it can brick your miner without any software solution.
You must put a correct firmware for t9+
How about using this firmware from here https://shop.bitmain.com/support.htm?pid=007201802091434313565J4tI3p60644
and use the sd card tool to make a sd card bootable and put the firmware inside the sd card?

I think after much reading I know the sequence.

Note in DaveF link above there is a V9 version of the firmware.

So first you download v9-SD Tools.zip

Then unzip that and get :
DiskImager    Application  88 KB    and      S2S4S5S7-img   Disk Image File  512,000 KB

Then - using the Diskimager program -  you put the S2S4S5S7-img file onto your SD Card. Then load the SD card software into your miner on a startup.

With luck you should end up with a miner that will get into the normal miner program.

Then using the update function from within the miner you update with Antminer-V9-20180312-600M.tar  which you should have downloaded to your computer previously.

The only file that ever gets put onto the SD card is the S2S4S5S7-img   Disk Image File

I would feel better if the name of this file included V9 but the title does say v9-SD Tools.zip

The main software ( Antminer-V9-20180312-600M.tar ) gets updated from within your computer NOT the SD Card.

At this point I am not ready to try this so cannot say it works. Use at your own risk!

Comments please if you think this is the correct method or is a wrong method.

There seems to be very little info available on how to use the SD Card. Maybe they think it is so easy us newbies should already know.
