You know, if you follow the directions that are posted by the developers on this website and you are of normal intelligence, you won't have problems.youre all my best friends , thnx for your patient . please one more question -
what i wanted is a guide or a link to a guide that will teach you what to do in case of the twrp is stuck , or something else that occoured on your operating system , and you cant flash a new rom with him ,or to boot into the system because something went wrong with the flashing process , in other words , you have to locate the original chinese fastboot of your phone and with him to flash the original rom ...i hope you understand my unexpert words... . i think that in this case you will have to extract the desired file to flash , not the whole zip file like you do with a regular rom , so i dont know what exactly to extract from this file , and how to flash it . a good guide will be just fine for me to learn .
and more -maybe there is a file that includes together the original chinese fastboot+the rom , it will be much better and eassier .
sorry if i wrote s tupid things , im not so expert , but i wanted to give more details as i can .
