Hacking 4.5 O3DS with Emunand: FBI injection, cold boot...

[Ronhero]

This is what I wanted to do. Impossible to install FBI to h&s and I don't know why. I tried everything.

Bet you this works. I don't like the rxtools one since it's usually broken. I bet this will help you finish my chain of commands

I talked about it earlier, it didn't work.

You can setup emunand right? And inject it there?

So go all new

format emunand > inject fbi to H&S to emunand > verify it works in fbi emunand > inject emunand to system nand > use rxtools devmode to install sysupdater and update to 9.2

I have done this about 10+ times and never had a problem

@Ekaitz try the Universal Injection again with the latest scripts, some changes have been made which might help you

 

[Ekaitz]

I'll try it again asap.

Thank you for the information.

Does it work now?

FBI injection can be interfered by Update Nag Downloaded 4.X & GW DG 4.X.
I know why it doesn't work and I have posted the reason on Riku's FBI manual installation post. Feel free to find it.

If it is interfered by GW DG or Update Nag, you have the following choices:
1) Give up injecting FBI to SysNAND. Use it on the latest emuNAND only.
2) Manually inject FBI to SysNAND.
3) Delete Update Nag / Restore Un-downgraded SysNAND before FBI injection.

I didn't have the time to try it.

But you gave me an important information: The sysnand was downgraded. (and atm I can't find where is that fuckin pre-downgrading NAND...)
