So ... you'd be best to just do the simple BM downgrade to a non-SSH lockout version, then install braiins

i assume you had the jumper correct and you could boot the sdcard.

Good luck if you decide to try it, post back your results!

With the halving well behind us and with summer coming I decided it was time to install Braiins OS+ on all my S9's for some more efficient mining.
All my S9's are running the March 2019 firmware from Bitmain that crippled SSH, so I had to use a SD-card to install Braiins.
But about 25% of my S9's are missing the U6 chip behind the SD-card slot, and these machines won't boot from SD.

What is the best way to install Braiins on machines in this situation?

Dear miners,

As you might know, we have been merged mining Namecoin (NMC) for several years. However, due to exchanges delisting it and a general lack of liquidity, it has become infeasible for us to exchange NMC for BTC in order to add it to your payouts.

Therefore, we have decided to send the accumulated NMC reward directly to any users who provide an NMC wallet address to claim their reward during the next two months. We apologize for the inconvenience this causes, but we feel it’s better than not distributing the NMC proceeds at all.

Moving forward, we will stop distributing NMC rewards due to the aforementioned reasons. We will reconsider this decision in the event that NMC becomes substantially more valuable in the future, but for the time being, we will begin using NMC merged mining revenue to support our open-source projects such as Braiins OS and Stratum V2 that bring benefits to the whole mining community.

Thank you for your patience and understanding in this matter.

.1 BTC for the next 18 or 19 blocks until halving.

where do you get this?

for slush I see:

137.94
10 blocks

105.26
50 blocks

99.84
250 blocks

Hi there,

I have been away from mining for a longer time. I opened a new account but was wondering if my original account "disclaimer201" still exists somewhere at Slush? I think I lost it and access to it when the pool website switched to the new design.

If it's gone okay, but it would be nice if there was some way to retrieve it. On top of the fun, I also discontinued using my old mail address, but I could reactivate it just for the purpose of recovering the account, if possible.

Thanks, happy new year 2020 to everyone and good luck mining to all!

once the 50 blocks gets to 150%  or the 250 blocks get to 97.5%     ill point 50% of my gear back here

this is why i make my own statistic... i keep a journal of how much block was mined everyday since in join slush 1 month ago. and maybe i dont calculate right but from the hashing power of the pool 4.5eh (slush pool) vs the total hashing power of the bitcoin community 57 eh (from google) it seem to me that somehow and somewhat those number should be at least related. and from the month i have passed on slush pool, it seem like that hashing power of slush pool does not bring its share of blocks and i wonder why. but like i said maybe it is me who doesnt calculate right. i am new to mining but i would think that 11% of hashing power would bring 11% of blocks and not 5%.
No?

The NMC rewards for the previous year will be paid out within a few weeks.
We are very sorry for the delay.

I asked about this, and there is good news for you:

There is nothing you can do when you are powering up a fan you get full power to it, until the controller boots and orders it to slow down. The only way to solve this would be with a hardware solution, such as feeding 7v instead of 12v for 1min or such...
