Hacking Problem with restoring Nand

[Lacius]

I have tried for two days to generate my 5.0.2 boot files
And I seriously don't get it. Have been following every guide I could fine, but I always hit a stop somewhere.

Follow Steps 1.0-8.3 of this guide. Then, restore the NAND backup with the system version that comports to the BOOT0/BOOT1 you made.

In other words, use the guide to make 5.1.0 versions of BOOT0/1, and then restore your 5.1.0 backup.

That is the one I have been trying to do.
I have never gotten Choi to actually extract the firmware. No matter what I do, it is always missing a key or similar.

I downgraded today.
Disabled Autorcm, and used "blank" 5.0.2 bootfiles + original rawnand.

Console was downgraded "succesfully".
However, it will not boot without a payload is injected first.
I cannot just power it off, and turn it on "normally" again.

Edit: briccmii fixed it!

Here is what I did, if anybody find themselves in this situation.

1: Restored blank 5.0.2 boot files, using the "ignore size check" from Mattytrogs switchboot payload.
2: Restored original rawnand.bin.
3: Restored missing bootsectors using briicmii.

- Thats it.

Thank you for the help.
Specially Lacius, who talked me through it all

Would it be "safe" to try take it online?
- Since the bootfiles have been restored they way they have, or should I keep it offline for now you guys think?

Could you expand upon this step? Did you obtain boot files from somewhere and restore those or did switchboot payload somehow generate them or...?

edit: I'm trying to restore a NAND backup from 4.0.1 to my switch but do not have the BOOT0/1 files and found this thread.
