@qaddory I'm sorry, if you are in a rush it's better for you to use other ROMs instead. I am extremely busy with my academics and didn't have free time for these kind of things anymore at the moment.
I don't know, you might or might not be a new n7000 user but here is what you need to do:
1. Flash everything back to stock.
2. Follow steps to flash Nightowl's Lineageos 14/15 with TWRP IsoRec support.
3. If you can get everything work with TWRP IsoRec at this stage then only you proceed with my instructions in first post.
There's no init.d folder because:
1. maybe you didn't mount /system yet
2. maybe you are on a ROM that didn't have init.d support, like stock ROM
logcat99 is a script and has to be placed in /system/etc/init.d
That's all. Bear in mind that all developers are doing everything on the forum voluntarily and we take no responsibilities at all, as per the disclaimer in the first post. It's up to you whether you take the risk or not, and it's up to me whether I assist you with your problem or not. Why I can't come up with a zero to hundred guide is because I need to test everything before writing a guide. I didn't have time for that. You have to know that all my development efforts are done in within my every semester break only. Just one month time. When semester starts, I have to stop all my development stuffs or my hobbies completely and focus on my studies.
If you are really in rush or you felt like unable to follow with my guide, I'm sorry, please use other ROMs instead. And also, I don't know what you mean by losing your data but I already have written that repartitioning is mandatory for installation and it will destroy your data.
