Help Android system recovery e3 after rooting

[Angiiie]

Hi everyone im kinda new on there so ill just shoot with a question ive rooting every phone with the KINGO Root software every phone was alright and also the recovery was correct with no problem so today i tried to root my Note N7000 but suddenly it didnt shows any errors wich could be a reason that failed the root after i booted phone up it was SU on it and everything nothing suspicious then later i tried to get in custum recovery and it pops out Android system recovery 3e wich never happened to me... could anyone explain me? i already tried to install custum recovery via "system recovery e3" but i got signature verification failed 3x times in row so i didnt tried anything else anymore... any help what could cause that? dont give me questions that the program is wrong or it causes by program if it was so i couldnt root successfuly 5 phones. thanks ladies
