Hacking Question DOWNGRADING

[MarzDaindigo]

(in the process of downgrading) how do I determine which firmware nand i restored to my switch so i know which FW binary files to pick and i can continue downgrading?

How are you downgrading?

You can look here to check the dump version https://gbatemp.net/threads/firmware-version-inspector-get-fw-version-from-nand-dump.515308/.

https://gbatemp.net/threads/how-to-...nofficially-without-burning-any-fuses.507461/

Just make sure you make a backup of your boot0 and boot1 files if you dont have any already. The nand backup you have contains prodinfo and prodinfof.......all of which are unique to your console

You are aware that you're gonna have to use RCM on every boot and load a custom loader every time right? That is unless you previously upgraded with choidejour and used autoRCM to prevent fuse burn.

Restored my old nand and then backed up my missing boot 0/1. Im at the step where im using my keys.txt and firmware binary files, ive download the fw files i just don't remember what version nand I restored

@Kafluke
I know , i have 2 switch that I accidentally left online so they updated smfh

You can compare your fuse count to the list to see what firmware you restored to.

Im not too knowledgeable about how many fuses ive burned, im guessimg the same amount it takes to get to 7.0 and idk what list you mean tho.

Use hekate to see your burnt fuses. Check here to see a list of firmware versions and expected fuse count.

So i have 9 burnt but the fw i restored to has a date of 12/2017, 7.0 definitely wasnt out yet. Will the fuse count change even tho i restored a lesser fw and im not on 7.0 anymore? I cant boot normal so i know it had to work.

1- 83

You cant restore to a lower firmware than your fuse count and have your switch boot normally. That's your problem.

Your fuse count is set in stone. You now have to upgrade to 7.x in order for your switch to boot normally. You can still boot to OFW through a custom boot loader like hekate but you'll have to do it every time you boot.

So i cannot downgrade or i have to figure out what my old nand is in order to?

You cannot downgrade at all, regardless of how you could do it, if you want to be able to boot your Switch normally. If you downgrade in any way, you will need to use Hekate or another bootloader in order to be able to boot your Switch.

Damn i hate being stuck without being able to play my "other" games but i guess i gotta wait for them to update reinx then

As I said, you can still downgrade, but doing so will require AutoRCM. Hekate will be used each time you power on the system. If you keep your Switch in sleep mode when it's not being used, this isn't a big deal.

If I were you though, I would just wait.

I know this isn't my thread but my need for answer are relevant

1. if a rebuild the nand of the same current installed do you still need autorcm/rcm?
2. does rebuilding the nand remove all traces of cfw?
3. if not is it possible to remove all traces, how?

thanks

1. don't understand what you're trying to achieve here. A clean legit system? of course you don't need AutoRCM.
2. Supposedly... no one really knows, but 3) it's your best bet

i was trying to achieve 3 but thanks and doing this mean i am required to have autorcm because of this even when u really just reinstalled the nand

Only if you're downgrading.

In theory it removes all traces but deleting log files is known to cause bans and when you rebuild the NAND you are essentially removing all log files as well as anything else that would normally be there on a not-fresh-from-factory system. And maybe even some things that are there on factory fresh systems. It creates the bare minimum for a normally working system which will likely have differences from a stock console.

thanks for the this but if we treat the switch like a android the device we are reflashing partitions which overwrites any previous data and there be no log to log there was any to begin with unless theres another partition such as misc partition that are in android devices, could this be answer for why people get ban for this?

It could be any number of things that are different from a stock console but blank/missing log files is an obvious one.
