To bypass the error while trying to flash to factory, i used the SD recovery method.
This time the flash was successful to NAND and S9 boot to factory OS.
Then i installed the 201711171757 and all three boards were working again!
Seems that 201711171757 is really a saver.
I tested to flash to latest 2018 firmware 201812051512 with success and all boards properly worked. Including of temp sensors!
I suggest you stay there then, that's asicboost enabled while still not locking you out of your miner.
