I am pretty sure I have seen the exact same hacked firmware that mines on Jp.nicehash , and I am pretty sure if you follow every single step I give you, you will be able to fix your miner.


1- Use the Ip-report button method to reset the miner ( no other method will work ) please make sure you read how to perform it and do it right.
2- Right after the miner turns back on from the reboot flash bitmain firmware ( prepare your DHCP table or AngryIP so that you log-in and flash the miner as fast as possible, try to do it in less than 10 seconds)
3- If the flash is successful ( you can tell from the firmware version displayed in the miner's status page) change the miner's log-in password ASAP

please follow these steps religiously, for the second step it's always best to have a tab with your IP range ready so that all you need to do is write the new IP address


and of course the firmware needs to be put in either downloads or desktop if you are using windows, it's best to have it in which ever folder opens first.
