Hi,  I have 2 chilis - one from Marto and one that is either from Lucko or MrTeal (I'm not complety sure-it is a dark green pcb with "The Chili Rev 2.1" written on the the upper left side). I flashed the Marto's board with the 1.0v firmware.  It went super - everything works way better.    But then I flashed the other board  -  2-3 sec. after the power cycle the LEDs 5,6,7,8 stay constantly on, 1 and 3 blink synchronously with rate about 2 times in 1 second,   LED 2,4 stay off.    What should I do?   The board worked 3 months wihout any problems. But now it is like dead,  windows doesn't find it.


P.S.  After a whole day of testing (multiple restarts and waiting together with some heating through a hair dryer)  the unit started, the leds went off and windows found the device.  Aftert a short moment of joy I discovered that only 4 engines are working - the others are missing.   I reflashed again with the same 1.0v FW -  but again - the same happened.   Next time I have the unit working Im gonna return to the previous fw.

P.S.2  Well.  After another day of testing I realised that I can not return the previous FW.  I'm stuck with 4 engines now.
Does the board have a rectangular white sticker on it that says something like
AMSXXXX
WO#DMXXXX-XXXX
REV:2.1

If so, it's one of ours. If not, it's one of the ones made by Lucko. I would say it's likely that it's likely that it is one of the Lucko boards if you needed to take a hairdryer to it.
Can you describe what you mean by you can't return to the previous FW? Does the flashing not work?

No, there is no sticker.

The flashing process now just doesn't work.   It hangs right away after i press program. Just about 1mm of the programming line is blue. The other 99% just stay gray.  I tried it multiple times. Even with a hairdryer before the process.  Im stuck with only 4 engines now.  At least it is stable now.   It makes no sense to mine with these boards now. In the next diff. increase they will be making only enough profit to pay for the power.
