Have your tried to reset the machine and build up from ground 0 ?
these are the steps i tried to do before posting
install official firmware
reset device
leave device open for 2hours
try to run board recovery tool from bitmain site
steps i did after i opened thread
installed vnish cfw
changed miner worker name from l3++ to l3a
boards still return 0 asic
is there any other step i can do?
i posted logs above
yes can mail me 1 of the dead boards and let me test it on my working l3 gear .
You only have 1 machine and
you may have 4 dead boards
you may have a dead controller
you may have an incorrectly programmed controller.
So you are dead in the water and need working gear to determine if your boards are dead.
I am usa based I am running 20 plus l3 and l3+ units
you have l3++ but the boards will work on an l3+ controller.
there is simply no way to help you without working gear being put into the mix
