my unit is connected via lan line is yours ? try a direct connection to your hub if possible if not
I connect to lan via ethernet cable and I can operate all functions of the board.
It responses very fast with renewed recovery soft.
you used the img tools etc to make an image for the SD card also correct
Yesterday bought new Kingston Micro SD class 10

format it in FAT (tried 16 and 32 bit) and each time when plugged after update, it started from the page where you need to fill the new password and login. So I assume that the soft renewal process went ok.
Although the LED light sequence wast as described in the KNC site instruction:
"A bright white light will flash inside the miner once, then a blue light will come on for around 30 seconds. Once the MMC has been programmed a green light will flash constantly. It means that the procedure completed."
I had blue lights flashing all the time and the bright LED was blinking for about 5 minutes from time to time (maybe 20-30 times).
other thing to try is to switch the psu that controls the controller board for power
and try bringing up only one cube at a time see how that goes
My set is powered by a new reliable server PSU (dell-2360W)

so there should be more then enough power for the 5 cubes, but I experimented with one cube also. Finished with them all powered and changing places wires from cubes connected to the board.
I have some thoughts concerning powering of the controlling board.
On the same PSU there is a lowering chip adapter from 12V to 2 pics of molex (made for powering 2 controlling boards).

Lowering chip should supply the boards with 1.5 A at 5 volts as it is required by the manufacturer. The parameters of the mini DC-DC lowering chip:
XM1584 DC-DC LM2596
Chip: XM1584
In: 4.5V~28V
Out: 5V
Out (max): 3.0A
Freq, Mhz: 1 - 1.5
Working temp: -45° +85°
Efficiency: up to 96%
Size: 22x17x4 mm
Weight: 3g

Maybe the right thing would be to measure the outgoing voltages but don't have the voltmeter on the hand now.
But want to add that mentioned above PSU was powering this KNC neptune set (5 cubes + CB) for 2 week and it was hashing without issues, and before, this very PSU powered 6 cubes+2 CB's without issues.
also I'd re-do the img on a diff sc card too boot I use Sandisk Class 10 8gb I had one did not work img to another and it worked tossed the supposed new one that did not work
Sandisk maybe better then Kingston, and I will go for this option again with another micro SD.
I still would like the update of CB happen with LED light sequence as described in manufacturers instructions.
you of course use the power Y adapters? you may want to check for connection of browning on that
No I dont use them permanently but I Tried with, no result. the connectors from PSU are ok.
you can pop the LCD screen and use that port as well for the heck of it
Quite interesting idea)) I have the version of CB without the LCD but I found the needed port
![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi60.tinypic.com%2F2hdthqu.jpg&t=665&c=9SIdV4F2_WlLFQ)
connected one cube to it, restarted the CB few times in different ways it didnt appear anywhere)
all I have off the top of my head besides just putting all your adv settings back to default 300 settings and maybe re-do the pool stuff (and or try a diff pool)
assuming anything on the controller lights up
Soft reboot and reboot to factory settings were my solution with the two boards I have on remote control, and it helped to one of them, another one also "lost" the cubes, but I currently cant access it physically.

So ATM 1 set not operating to which I have access now, and 1 set on remote control not operating.
Other sets I have work ok.
was a guy on here newbie who SAID he sent his Titan controller in ...don't know what he paid or if /when he got it back was not long ago you may want to contact him
on what he tried or was told to try assuming he did contact knc (big if)
I contacted KNC support and waiting their answer now for possible reasons why CB doesn't see the cubes, or why they can disappear and then appear back after soft reset.
er almost forgot IMPORTANT
IF YOU HAVE A JUPITER/SATURN/MERCURY OR WHATEVER controller card from a previous jupiter 550gh or whatever you can REFLASH that board to work
with a NEPTUNE
me with a titan i don't have that option it uses a PI ..saw one go for 86 bucks on ebay just a few days ago
so at least you may have that work around if you have access to stuff
and other then above....the hard reset button trick and just start over with all and a newer SD image trial again
anyway again all that comes to mind
all that comes to mind now let us know how it works
I have only Neppys, but Really good ideas from you buddy!
Will keep on experimenting and update when there is something new.
All this case is quite wired...or i should say weird)
Finally if everything will not succeed will look for those PCB's on the market...
