Hacking Boot without RCM after a NAND restore

[navega]

Is there a way to fully restore the nand to go online after using cfw?
I did restore my 8.1 firmware using the old 7.0 nand successfully but now I cannot boot without using RCM.
When i try without RCM is keeps on black screen. Am i missing something here?

How dis you restore your 8.1 firmware ? With choi ? Autorcm with choi is enabled by dedault

The firmware is part of the NAND. If I understand it correctly, you were on firmware 8.1. and now restored a firmware 7.0 NAND. If you burnt fuses while being on 8.1, the 7.0 firmware now cannot boot because the number of fuses do not match.

Try injecting SXOS or hekate payload and select boot original firmware. This will bypass the fuse check. Then go online and let the console update itself to 9.0.1.

As mav2010 said.., boot hekate.. and check how many fuses are burnt..before going online
