[Galaxy Note 4 Android Development (Snapdragon)] logosA:
Guys I know I have spam this thread alot the past weeks and I want to ask sorry for my long posts and thoughts that maybe had made you bored , but I just want to share my findings with you.

Maybe someone else reading that, can avoid pass throught all these and find a better and faster way to fix his phone.

So today, I am coming back from a 15 hours marathon that I had made since last night , trying to restore my phone to the best possible position.

to do that i have: Samsung Note 4 N910F

1. flashed 3 times stock rom ( 2 different MM versions) using ODIN and eur open pit

failed all the times

and this just i the last 0.5% , I think pit was the problem or a hardware fail of my phone.

I was trying to erase all nand backups and make my phone able to boot by its own and not anymore with the use of the debrick SDcard

2. Flashed (twice each one) 3 custom roms . RR 5.8.1 , Emotion OS 20.2.17 and ''Full Note7 Port for N910F''

failed each and every time

, never managed to flash through TWRP none of them, ''System flash failed''

3. Using the debrick sdcard and all 4 recovery files mentioned in the OP posts, flashed Samsung recovery software which made my phone to recover again and after 2 major updates to reach the latest MM rom available for our phone, managing also to remove all NAND backups made before with the countless flashes that I have made.

This is the only thing that is working everytime with my phone> use debrick sdcard >flash recovery files> boot phone and update to latest rom.

Even now , after all that I have done, my phone can NOT boot in recovery,download mode, or in system, without my debrick card put in my phone. The only thing I have to do is put card, press power, phone boots with no problem. After that I remove the debrick card (safe remove through storage menu), put in the normal ext sdcard with all my files and phon is working OK, if i dont chose to reboot , power off, or reboot in recovery.

This had made me think that this has to be hardware issue and can NOT be fixed.

But, I can deal with it know, I cannt do otherwise :(

I have learned two very important things ( in my opinion) that I want to share

1. As i have posted 2 post back I found the method to let me keep my phone cold for a very long time ( without to put it in the freezer)

TAKE A ICE CUBE VESEL, PUT IT IN A ZIP BAG, TAKE OFF THE BACK COVER OF YOUR PHONE, PUT IT ON ICE

for 7 hours I was flashing, moving, installing things in my phone , without a single freeze or reboot.

6 times flashed things in odin , one after the other, NO PROBLEM at all. So keep it in mind

2. As I am not able to flash a custom rom, I found this which is the next best thing

This removed all bloatwares from my phone, rooted it and my phone is now as close as can be to stock, with all things working but without the disadvadages of the stock rom. And this without changing nothing in my ROM. This way phone is faster than ever, smooth, ROOTED, and no overheating anymore as 30% of process used to run from stock (without needed) are removed

Take a look and listen to my advice.

Its strongly worth it
