yup.

It isn't that you are downgrading..
It is that you need to flash a pristine stock of diablo (then put only what is expected to accomplish what is needed next ..to avoid conflict or complication..) if you wish to then go the next steps further with cssu, asui, and diablo turbo.

Of course it depends on what your intended usage is....
you may want to study a flash version ....or utilize a specific from an iteration of some earlier flash version


And ,,.... NO
you do not need to downgrade to utilize peguinbait's tools..
these particular tools have been integrated into console tools v1 ...
which works fine for diablo.

Just remember please...

If the intent is to learn how to do something ...
read said instructions ..do not deviate in replication ...
and you will be fine..

If the intent is to study, dissect, alter, refine, and / or come up with innovation ..from a methodology, process, program, or function...
then the expectation is that you already know the basics .....

Do what all instructions ask of you in whichever members walkthrough...and you will replicate the same results required in your n8x0


Some instructions may state that they will not work with earlier or later os versions ..
Some instructions may say that they have alternatives in this case for said versions...
Some instructions may say that issues have been noted in use with other versions...but they are on the whole functional...
Some instructions may say that there is no reason it shouldn't work with later versions ...but has not been fully tested...
I have tested penguinbaits console tools v1 enough over the years to know they work fine...
His other tools do just as good a job for the specific os or kernel versions as well...the ones he specifically points out their use for....
