there's nothing wrong with the tutorial. If you have a Crystal 2 is a quad core and not a dual core. Totally different SOC. If you meant batch 2, I had one and it worked fine for me.I have Novo 7 Crystal 2nd.
I Use TWRP v188.8.131.52 and this dont work for me.
I have often tried TWRP and after NOVO logo nothing happens. So I used the 10.2 version with TWRP v184.108.40.206 and could be started. Unfortunately, there were problems with the SDCard. It was not found. I used this switch and it works perfectly.
Pls fix ure Tutorial Christian Troy
