How would i go about updating ? Any new features on that update ?

You actually want to buy another L21 ? With the issues it gives and difficulty being what it is now i don't see how mining ltc is profitable , better off buying the coins directly specially since its so low these days .
At this rate we'll be making .5 ltc a month per miner very soon .
I don't want to buy, I have to many already
I was just checking that information.
They have released a new firmware btw. It solves nothing...

BITMAIN killed this little company .. 
What is so funny about BITMAIN killing other companies that makes you grin? It would be bad if they had a total monopoly instead of the big market share that they have now.
BW.com is still a operational company, so your claim is false.

I decided to try the BW shop you mentioned before and they don't sell the L21, just a PSU, an ethereum rig and case. No mention to L21 in terms of price or availability

I cant get a reply from the company CEO in weeks, but I still talk with Brett and some of the staff several times a week.
Today I got the new firmware.
It doesn't solve the issue with the December batch, and I don't have the changelog so I can't really tell what's new about it. It did solve a issue with one of my miners that was "half-bricked".
Has far as I know, BW already has a fix for the issue with the December batch but hyperbit themselves are still waiting for BW to fix their own miners.
They don't know when that's going to happen... but at least the reply from Brett has changed from "no idea" to "soon"
They stoped advertising and selling because all miners BW built since December had the same unknown issue so they couldn't put them on the market.
I believe they're so full with emails that decided to go radio silent till they have the answer everyone wants to hear. But this is just my opinion (very positive)

Hello,
Be sure to update the password while in the CLI. Also, update the passwd in conf.default file.
Running four of them I picked up. Updated to 2.60 without an issue. Even noticed the rejected rate moves around as well. My A4+ pop up with rejected packets from time to time.
Regards,

Yeah I have not heard about Hyperbit for a long time.
Their last activity in social media was in January 2018.
I guess it could be that Hyperbit is not an operational company anymore.
Brett was really pleased with my review/guide documentation, I let them use that as material for an official document
and he promised that I could get a free BW-L21 unit as return.
This was back in October 2017. I have not received that unit.
Oh well, I guess it is time to move on.
BW.com has opened their own webshop and will most likely start selling their hardware directly to customers.

Seems like hyperbit stopped all comunications . Use to have some kind of dialogue with them but nothing for weeks now.
Anyone had success with fixing this issue ?

I have updated this review slightly and there is now also a nicely formatted version available (.pdf document).
EDIT:
I wanted to try out this new platform and the review is now also available in the Steemit blogging website.

I'm still going to continue as before. Posting here at the Bitcointalk.org forum is my priority number 1.

using pro hashing and choose LTC is more profitable than actually mine LTC?

Thanks for sharing this info.
Good to know that they are working on a solution to fix the issue.

Would like to note here that over the last week our L21s have been hashing well at prohashing. The accepted rate is almost at dashboard level for about 1/3 of them and is in the mid-500 MHs for most.
What's the pay system you chose ? I been meaning to try prohashing .
February 07, 2018, 10:43:22 PM
It is a software issue...I work pretty closely with them since my miners use their chips. Been trying to get a L21 unit from them to help them fix the software but so far they have been out of stock and cant send me one.
What do you mean by "my miners"?
His latest product is FutureBit Moonlander 2, which is a USB stick miner.
It uses the same 28nm ASIC chip as the BW-L21 miner uses.

Obviously there's something wrong haven't you read the previous post where i clearly say that i have tried contacting BW and it did not work .
Great help reminding me to contact BW , amazing effort .
Again sorry for hurting ur feelings snowflake , now i know people wasting their hard earn money < ur over sensitive feeings .
PS:i never screamed at you , criticism does not equal screaming.

Easy now! He just reviewed the miner. We operate the L21s as well. Although we mostly run Bitmain products, we do have 12 of the L21s. I can tell you that it's not a latency issue. It doesn't matter which pool you point to, it's still a problem. There is a high number of rejected shares on all of our L21s (10-40%) and the reported hashrate (as a result) mainly fall mid to upper 400 MHs.
This is a real issue. I am not sure if BW will fix it or not. I know that Hyperbitshop's CEO just told a friend of mine that he would get to a firmware update in a few weeks. But, seems as if Hyperbitshop isn't selling the miners any longer since they are listed on the BW.com site.

I've been in touch with hyperbit guys and for those who bought from December batch there's an actual hardware problem.
They found a defect with MOSFET in power distribution board and are trying to get new boards to ship to buyers.
Also, the new firmware should improve the global hashrate by having fewer rejected shares and better memory management blablabla.
The new firmware should also bring fan control so it's no longer running full speed.
