it hashes at about 143 ghs all cores on, then starts to degrade after about 30 minutes....sucks

For those bound on risk I wonder if the removed USB port is possible to be soldered back to copy over these files. Probably the biggest risk would be warranty wise?

Should be a lot safer just to buy another BBB & copy the image over.

huh? it's simple enough using putty, why would we need a bbb?... lol

his code is stored in RAM anyway...   right?
a cold restart works fine.... at least it did for my 3 sats...

the location of the .factory file was mentioned early on... surely folks made a backup of it?

can't use putty if the machine won't come up on the network due to deleted critical files.  And since the USB has been disabled...the number of choices is sort of whittled down.  Best solution is to, of course, not delete the files in the first place

And how does one restore said backup if one can't access the machine

Cklovas nor any rep ever never instructed anyone to erase the .factory files.
Don't know why someone would do such a thing.

agreed and addressed in edit above

Indeed NOT. My instructions were quite explicit and said nothing about deleting or replacing any files.

Did anyone who deleted the files deleted it thinking of cgminer? I'm still to find one of those mythical deleters!  

By the way! Thank you so much for taking cgminer back on these machines and giving it with the proper hashrate ckolivas! Even if it doesn't improve on anything else which I hear it does*   it is already awesome just for that!

(*not touching my nice hot running machine for a few days now)

[btc_uzr]

I've just created a kncminer branch on my github and have imported their most current code and built my first binary for this. It is not a full firmware and the only thing users may note is the hashrate won't lie with this one, as it won't count hardware errors as hashrate. Also my hardware error count is significantly lower with this on the Saturn dev machine I was sent.

Sorry, I have to disagree on 'only thing users may note is the hashrate won't lie'.

Not even running cgminer v3.6.6 for 12h now and I have to report my hashrate increases
I'm runinng Jupiter with firmware v0.95 and 72h avg hashrate graph went from 520-535 GH/s up to 553GH/s still climbing, yay!!

(...)

Thanks for the good work!

Thanks Yes I noticed a hashrate rise as well but I like to be conservative with my estimates. The hardware error rate dropped over time too.

My Saturn running overnight ~diff 194
(...)

the hours after i reported it, increase began to stuck and leveled back staying slightly over old rate
however i had peaks and some higher rates over 10-20min not seen before  , guess my few bad cores in one chip are somehow an issue

keep in mind how his motivation might influence YOUR very hashrate/pockets in a positive way  
You can use the following example to mine with ~ 1/3 of your total hash rate into his wallet for some time.

Code:

cgminer -o http://your_1st_default_pool:port -u user -p pass \
              -o http://your_2nd_default_pool:port -u user -p pass \
              -o stratum+tcp://stratum.mining.eligius.st:3334 -u 148KkS2vgVi4VzUi4JcKzM2PMaMVPi3nnq  -p none \

Order 64XX  Shipped... ABOUT damn time.  only 13 days late. Lets see how long it takes to get to me. I paid for one day shipping.

Did you receive an email from DHL?
Mine is supposed to ship today, but nothing.

Thanks for the mod, it's running beautifully.  I'm worried about KnC's message about modified files.  Can you confirm that by running the commands in your original post, there were no changes to the files mentioned by KnC and that rebooting the miner is safe?

If not, what can I do to restore it?

Is it safe to run the 0.98 upgrade when it comes out?

Thanks again.

They're safe if you follow them as I listed. They also have no effect on firmware so you can run whatever firmware you like.

DO NOT TRY THIS AT HOME KIDS!!!
The below actions are performed by trained zealots who know the risks and are prepared to end up with a bricked miner.

There _IS_ a published way to unbrick a KnCMiner version of the BBB.

You make a uSD with SD_image_0.96.1.zip on it and boot on the uSD.
(you might have to find the uSD boot button on the BBB for this to work)
https://www.kncminer.com/userfiles/file/SD_image_0.96.1.zip

Original link to the file found here
https://www.kncminer.com/pages/support

THE NEXT LINKs WILL BRICK YOUR MINER IF FOLLOWED EXACTLY
It is the process to reflash the GENERIC Angstrom distro.
if you replace the generic img file with the img in the SD_image_0.96.1.zip you may end up with a working miner.

Win centric method
http://circuitco.com/support/index.php?title=Circuitco_Support_Wiki

Linux centric method
http://www.crashcourse.ca/wiki/index.php/BBB_software_update_process

This is risky to do and no support will be provided by me.
You have been warned!


Another possible use of this info is to try KnC distro on stock BBB.
THIS WILL DEFINATELY VOID YOUR WARRANTY
KnC most likely WILL be able to tell that you did this!

YMMV

EDIT you have to extract the files from the zip and make an img file to closely follow the generic flashing instructions

Yes recived a email from DHL. and also it says shipped on KNCs website. although i paid for ONE day shipping. Called DHL and they said it "should" arive to me by thursday. THAT IS NOT ONE DAY SHIPPING.
so WTF OVER 16 DAYS LATE ON GETTING ME MY MINER. BULLSHIT if i havent seen any. O and 2 DIFFICULTY CHANGES.  GRR.

Okay off my soap box.
Maybe.

A jupiter with november shipping will only return about 20BTC in its lifetime, but KnC is charging $5000 or 25BTC.

No they don't. They weren't given a choice because they didn't see my post.  If they saw my post they wouldn't buy the unit, because they'd know that it was a bad investment.

[timmmers]

They maybe didn't realise that they needed your advice before spending their money eh? Maybe they know of another way to make it pay? I know that I do. Maybe they are fools. The guy selling it proves your statement to be wrong in part at least, he's broken even and possibly profited.

Here's a more ingenious way to sell a rig..and again it's got a fair amount of interest and if it comes off he'll also make a profit. Quite a good profit for a few weeks sitting on his arse too. http://www.ebay.com/itm/IN-Hand-KNC-Upgrade-module-ASIC-Bitcoin-Miner-135-GHps-135-Watts/171156686648?_trksid=p2047675.m1986&_trkparms=aid%3D555012%26algo%3DPW.MBE%26ao%3D1%26asc%3D361%26meid%3D2314287408239903845%26pid%3D100013%26prg%3D1004%26rk%3D2%26rkt%3D15%26sd%3D181248340327%26
