Here is an extract of the codes .... have seen it although 42801 contains 88chips and that 42701 contains 108 ....
So, if you swap eeprom, there will automatically be an error and therefore the miner will not start.
Of course, if you flash a T19 eeprom on a S19Jpro... it just won't work! there will be an eeprom error...
But if you flash 42701 on 42801, the miner will start, pass the eeprom test (because they are both listed in the S19Jpro firmware), but when it looks for the number of chips, it will only find 88 instead of 108, so error find all asic...
On the other hand, flash BHB42631 on BHB42651, or the reverse, and it will work perfectly, and yes, they are simply the same hashboard! just a bitmain glitch to piss the world off...look on the hashboards, often there is the name GRAVE on the hashboard, then over it a simple label...that proves it
