[Galaxy Note GT-N7000 Android Development] Gold Mix:
Well, this legacy low-end device has been long abandoned, and people have moved on to newer more capable ones. I believe it's highly unlikely you will get any professional advice. and your only option is to experiment with it, but after doing some research of course. I have asked a number of questions in this thread, but no one even responded at all :(

Anyway, this device can't efficiently run current apps, so it's not suitable to be used as a daily driver, and probably only good for experiments. Actually, I have learned quite a lot about Android from experimenting with it, and the best part is you do it without fear of bricking and losing this worthless device :laugh:. Luckily I didn't encounter any hard bricks but some boot loops and kernel panics, which I was able to solve by "intelligent" experiments after searching the Mighty Internet.

So, I'm no expert in anyway. I just probably know one or two things, but I believe it could solve your issues. I think you have 2 choices:

**********************

EDIT: I just thought about this now. Before you try any of the steps below. Have you tried to factory reset and re-flash isorec twrp? You are are already running Lineage 14.1 which means you have the right kernel and no need to re-flash it. I have a strong feeling that re-flashing isorec twrp and factory reset will solve your issue. By the way, what twrp version does your phone have now?

***********************

A. Start fresh and fully go back to stock.

Flash latest stock rom and pit file using Odin, iirc it was JB 4.1.2. I believe, you can also do this using Samsung Kies but never tried it. I believe it is highly advisable to do a factory reset, and even a full system wipe before doing this

B. Use the preparation method for [MENTION=799465]bauner[/MENTION] Nightowl Lineage 14. 1 in his thread

1. Flash cwm recovery PhilZ-cwm6-XXLT6-XSA-5.06.1.tar.md5 by using Odin or mobile Odin. This will give you a yellow triangle but I believe you already have it. You can remove it later by using TriangleAway. I have used it twice on this device, and it works even in this Pie rom

2. You should be able to boot to cwm recovery. DO A FACTORY RESET

3. Flash kernel https://xdaforums.com/devdb/project/dl/?id=20863

4. Reboot recovery

5. Flash TWRP 3.1.0-0 isorec recovery

Hopefully this will work, and now when you boot to recovery you will have the normal twrp 3.1.0 and N7000, and you can boot Nightowl Lineage 14.1 or install another rom if you like. If you see anything not happening, according to these steps, have no fear and try to experiment and shuffle the steps and do more factory resets, even /system wipe if you don't need your current rom. This method helped me get out of permanent kernel panic, but I didn't have to do /system wipe. I just re-flashed the emulated twrp and kernel for this rom and my phone started working again

I'm still on this rom, I really like it, but I'm not too sure about it any more. If I get another kernel panic, I'm going back to [MENTION=799465]bauner[/MENTION] Nightowl Lineage 14. 1

Good luck :)
