Dayun Zig Z1 - Lyra2Rev2 6.8GH/s Asic miner

[mattaero]

Hi,

Did anybody buy from these guys:

http://www.dayunmining.com/

Claim to be direct manufacturer

Any thoughts?

They are not.  And the prices alone suggest it is a scam.

Look...Almost the same page... https://dayun.company/

I bought my Z1+ from Akminer.com. I suggest you WhatsApp them for a price as they delivered within 3 days and also helped me with customs. I will definitely buy from them again

The machine had been running for just over 23 hrs for $20.

to Zig owners,

do not use untrusted or untested image. because some of them usually have phpbash.php, cc99 and powny. they are illegal software or scripts.
some of them has extra user like pi or fa. please be attention of these.

phpbash and pi/fa users are present in the factory image.

Was anyone successful in flashing one of the version (20180930 - 20181015) onto a new usb and having it work?

If so, did you do anything special appart from using udisk ?

Here's how I messed up. I only went to login screen the first time. I tried the root/envision some people gave but it wouldn't login.

I then switched the usb to my PC to see if I could disable the password but got welcomed with a "you need to format this drive".

Test on 3 more pc, same result.

Tested again the miner, couldn't get in.

I've decided to flash the latest version, but now no matter what I try, I can't see my miner since I wiped the usb that came with it to try and upgrade it.

Check if a Tomax can help as they are a massive supplier of miners and they may have a relationship with DaYun as well. Maybe they can drop the entire usb drive contents on a zip file and send to you. I am not that technical else I would have tried to help. As mentioned is my previous post, I struggled to set up the IP and when I got it running I haven’t touched it. Also, my hash rate varies from 2.5 to 7.5 GH/S and I did read a post that deals with that but I am going to settle for my $20 per day and not touch the machine. Also saw the temperature running at 50 degrees for the core and the 4 units were running at around 69 degrees as my garage gets very hot and this machine throws out lots of heat. Not too sure if there is a risk with that so please let me know

Well, they provide a program (made by a known team) to either flash some boot file to the usb or to extract them (make a copy on your pc)

If you feel adventurous enough to stop your miner, I'll be real happy to get this file

asicminervalue indicates income of $24,03 for the Z1+ However I am only getting around $20 through NiceHash. Any recommendations on a pool where I can get the full value

[jensenj]

I just got the Zig Z1+ with firmware 20181015 firmware for days ago. Had to change my router to 192.168.1.1 to be able to log in.

While I can log and set the parameters for Nicehash and log into the interface it always says offline and dashboard says "Miner may not start".

Anyone else got a Zig Z1+ working on 20181015 firmware?

Otherwise, I might have a bad unit.

I also have the Z1+ with the 15 October firmware which I received this past Thursday. Also struggled with the IP but once I changed IP range on DHCP, it found the Z1+ it works fine

[mattaero]

Anyone know where I can get the original firmware... I had it running great at 1000 mhz, then updated the firmware, and its having serious issues.  WTF.

If you get it from someone, please let me know. My miner never ran as I broke the original usb and 20181015 won't work.

It turns out I had saved the 09142018 version to my computer.  When I created a boot disk using it and the imageusb.exe then went and changed the miner.json like noted earlier, it is back to 7.2 on my Z1.  So clearly something changed in the later firmware

Got this mail from Dayun:

[Dayun Company] Information about Profitability

 

We noticed that the profitability of our equipment dropped to $20/day.

This problem will be solved by November 1, the complexity of the network will be increased, and earnings will be restored.

In this regard, we offer you a coupon for a discount of 14% (free shipping is included), which is valid until October 31.

Discount code is: —

Thank you for staying with us!

So, what’s up on Nov 1?

I have 15102018 running at 975mhz stable, 7.1 hash rate on average. Any higher clock speeds than that, the chips start failing.

It'll be interesting to find out what they mean with that email about earnings increasing.

They pull a Thanos, and remote-brick half the Z1 miners already running. Allowing difficulty to drop, and profitability to return for those Z1's who remain.
