few days ago i got my first new l3+ and stupid me i havent change the passoword so he got hacked....
i try to  flash it with an sd card of 16g but nothing happend...at 19.00 my local time take over the miner and change the pool address...
i dont know more what to do...
i download the last l3+ firmaware and flash it.... but maybe i did somethings wrong ....
do the internet cable need to be connected during the flashing??,,,
and after its flash ...
how can i see if he really did it ?

maybe its the sd card
its new...but 2 or 3 times i disconnected just by pulling it out but after i have been format it at 32 fat and place in the file ...
 im kind of lost...
