Restoring Bitmain Firmware (V9, T9+, others)

[DaveF]

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:

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   ?

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

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.
