(Review/Guide) BW.com BW-L21, 550 Mh/s, 950W Litecoin (scrypt) ASIC miner

[HagssFIN]

I was able to get in touch with bw support . They send me the latest firmware update they have , so now bwminer is at version 2.8 and cgminer is 2.9.1 .

Now my rejection rate is Between .30% and 1 , huge improvement from 6 to 8% . Hash rate seem to vary between 520  and 570 , rately goes down below 500 like it used to.

They sent me a way to do it with windows using winscp ... took me 60 sec to get it done ..

Cool.
Can you post it here?

What's the firmware revision?

Did you get in touch with Hyperbit or BW themselves?

[Seph213]

Not sure what’s the firmware revision but i’m assuming it’s 2.8 since my UI says bw version 2.8 . CGminer is at version 2.9.1

I got this from directly from BW , hyperbit support never answered their emails since i got this miner .

I’ll upload the files , am i able to simply post the file like an attachement ?

You need to use a file sharing website, like Mega.nz for that purpose.

[apax]

that's weird... hyperbit told me they were the ones developing the firmware now, but also stopped replying about 2 weeks now.

the UI version on the dashboard is only regarding the UI itself, not the machines firmware.

[prokola]

There's still no official release of the new firmware so I'll try to share it with you.
It's not as easy has the previous updates, but I've managed to do it with no problem having only a very basic knowledge of unix terminal.

These are the instructions I received via email from hyperbit:
 

Code:

1. You'll need sshpass and parallel installed on whatever machine (UNIX) the script is run on. Links below.
2. tar -xzf 2.9.0.tar.gz
3. cd 2.9.0
4. Edit ip.txt and specify the IP address of the machines you want to update (one per line).
5. ./run.sh

Note, there will be lots of output as each machine is updated. 
Some of it may look like failures, this is ok and can safely be ignored. 
The updater is built to work across many potential versions and tries to fix various things on the system. 
Some of which may already be fixed, so the output reflects that.

Install sshpass: https://gist.github.com/arunoda/7790979
Install gnu parallel: https://www.google.com/search?q=install+gnu+parallel
If you're using Mac as me you'll need to install brew

firmware files: https://www.dropbox.com/s/indgp8nlnk3372s/2.9.0.tar.gz?dl=0
*please note it's my dropbox link, they sent it to me via email.

Hi, please post a working link to the file with the firmware. Old link not working

[prokola]

Can anyone help? I even have the old firmware version 2.6 stopped installing. Who had it?

People, be careful.

The file that username Seph213 sent me,
gave a bad result in the virus scan.

I used the VirusTotal service (www.virustotal.com).

See the test result for the archive file here (click for a high resolution image):

In the version you have is there an admin password to access the webui ? Or is it like the other versions ?

In this version there is no interface for entering with a password, I did not immediately notice it ...
although this section was on version 2.5.0, it still did not work

[klintay]

is there no cgminer or bfgminer support for this device?

https://hyperbitshop.io/ does not load correctly for me...seems to be defunct

I already had 2.10.3 from hyperbit since July.

I tried this 2.10.3 and i saw no difference in the WebUi at all .. what’s the advantage of that version ? Cgminer 2.9 that bw sent me fixed the high reject rate problems .

[apax]

UI is the same from many versions ago.

I never had issues with rejections.
