Hacking Question Bricked Switch

[Lacius]

Well after days of trying an trying , I seem to be getting somewhere

switch now boots ( downgraded to 6.2 with a lot of help from Lacius )

But still isn’t booting .
Used the guide , followed every step .
But getting error code 2005-0005
Loading using FUSEE Primary.bin just goes to a black screen.


with and without a micro card in it

cfw also throws up that error

weirdly when I use Lockpick or Biskeydump I get a error of KeyBlob 0-5 is corrupt , but I know all keys are good as I checked them in Hactool when I downgraded.

the good thing is that it boots , but still not working .

many ideas before I have to send it away to be repaired ?

also if anyone knows a place that repairs these things that would also be great

thanks in advance

This doesn’t make sense

@ethanhawk and I have been communicating over PM. He hasn't answered some of my questions, and he's doing things outside of what I'm telling him to do, so I gave up on troubleshooting. Despite receiving a private message from him a few minutes ago, this post is also the first I've seen a lot of the information being provided. I imagine the problem is user error. Good luck to anyone who chooses to help.

Sorry

should have said
The switch now boots to Nintendo logo , then switch logo then throws up the error code 2005 0005

what I meant was it boots further than ever before

but to be clear
I followed every step of this :——

1. Make sure the SD is FAT32. Reformat it if you need to, making sure to backup the contents of your SD card beforehand.
2. Dump all files in Dump To SD to SD card.
3. Mount emmc using memloader
4. Restore console using "Use On PC" - "6.2.0 restore Files". Follow manual Choidujour downgrade tutorial, but use these files in this archive (skip boot0 and boot1). In other words, follow Steps 7, 9, 10, 11, and 12 using this guide.
5. Power off
6. Boot into RCM
7. Launch hekate_switchboot_mod
8. Restore the special BOOT0 and BOOT1 on the options.
9. Just follow down the menu. Enable autoRCM if needed
10. Make sure you are at main menu.
11. Select launch.
12. Select UNBRICK_FIRST_BOOT_ONLY

I’m not sure how it can be user error if I’m following the guide you sent me .

I restored the backup , then followed TUT.
Once all that was done and it didn’t work , I used lockpick , biskeydump and other playlods to see if a) keys where right B) to check if it booted with other play loads

but as I said I do Appreciate you taking time out and helping me .

 

[magico29]

Listen, before do anything make sure to check your clean rawnand.bin via hacdismount, looks like you desperate and you gonna make a mess.
also make backups for boot0,boot1, and sysnand.
your keys wont be any problem as soon as you dont touch them via hacdiskmount, so forget about keys.
right now the problem is what you installed on the system.

 

[ethanhawk]

Thanks ,

I did check that it was a valid dump , keys worked and nothing was wrong with it .

I stored it , then followed TUT .
As I said Switch now boots pass Nintendo logo , goes to switch logo then throws the error code 2005 -0005 .

 

[magico29]

what experience do you have?
enough to scratch from 0?
what tutorial? downgrade via choi?

 

[ethanhawk]

Not enough ...

yes the downgrade via choidujour Tut .
But using a guide lacius sent

1. Make sure the SD is FAT32. Reformat it if you need to, making sure to backup the contents of your SD card beforehand.
2. Dump all files in Dump To SD to SD card.
3. Mount emmc using memloader
4. Restore console using "Use On PC" - "6.2.0 restore Files". Follow manual Choidujour downgrade tutorial, but use these files in this archive (skip boot0 and boot1). In other words, follow Steps 7, 9, 10, 11, and 12 using this guide.
5. Power off
6. Boot into RCM
7. Launch hekate_switchboot_mod
8. Restore the special BOOT0 and BOOT1 on the options.
9. Just follow down the menu. Enable autoRCM if needed
10. Make sure you are at main menu.
11. Select launch.
12. Select UNBRICK_FIRST_BOOT_ONLY.

well, i cant tell you cause you gonna get things worst.You need to do the hole tutorial from scratch, meaning you gonna erase the switch memory and reinstall a manual downgrade via choidujour, keep on mind:
You cannot upgrade or downgrade directly to any firmwares from 6.2.0-9.1.0 as the ChoiDujour PC application does not support these firmware versions. You must upgrade/downgrade to any other firmware version first and then upgrade to these higher firmware versions with the ChoiDujourNX Switch application if you specifically want one of these firmware versions.

ChoiDujour and ChoiDujourNX are not the same thing.
there is a very long process, you need read a lot before try anything.

 

[ethanhawk]

Mmmmmmmm well this guide has me putting 6.2.0 on !

but your saying 6.2 doesn’t work .
Or am I reading that wrong ??

 

[magico29]

no you not, if you use ChoiDujour.exe on pc doesnt support after 6.1, i used that method before downgraded to 5.1.0 and then update to 10.0.0.
conclusion: if you aren't ready enough don't even try, read learn and then you can hook with the hooker.

 

[naed06]

Did you not read the big red warning on the guide site you posted??? It tells you there it doesn’t support 6.2

https://switch.homebrew.guide/usingcfw/manualchoiupgrade

read the BIG RED WARNINGS at the top of the guide

 

[magico29]

yes, hes not even reading. That's why i said it.

 

[ethanhawk]

No m8 , I didn’t as I was following Lacius sent me , which included the 6.2 firmware files.

I followed exactly as he said

why would I question it , if it Lacius said to follow it and use files he sent ???

 

[magico29]

make sure you have all backup files please.
boot0
boot1
sysnand
rawnand
biskeys also just in case
if not and you mess the switch, save money to either a new one or Nintendo fix.

 

[ethanhawk]

i Currently have them yes

so it’s best to do a restore first .
And start from scratch with any firmware lower than 6.2 ?

What’s best way to wipe the switch memory ?

and thanks for putting me straight , I clearly followed the instructions I got but seems there where wrong not me

 

[magico29]

you just need to follow the hole guide from 1 to 13. I am just telling you if you aren't feel good enough don't do that and find someone else do it for you.I don't even speak English and i did it. Also do no move to the next step if you see any prior error, all steps has to be finished.

[ethanhawk]

To be honest , the guides pretty simple .

I was clearly using the wrong guide .
As I stated , i followed the instructions Lacius gave me .

Thats all I could do . I took advice from someone who knows much much more than me . Surely that’s all I could do .

I asked for help and someone gave me a guide to follow .

so thanks for putting me straight and hopefully this time it will work .

Now that guide doesn’t tell me how to wipe the switch memory ? Is it just a case of deleting the files when I mount the user, system drives ????

 

[magico29]

you have all backups as you said, if not get all backups that i told you to get.
boot0boot1
sysnand
rawnand
biskeys
place them inside a new folder and do not touch them, on the guide you gonna plug the switch to pc.
also make sure to get firmware files lower than 6.1.0 to downgrade, follow the guide and DO NOT SKIP ANY STEP.

 

[ethanhawk]

I’ll give it a try tomorrow
Fingers crossed it should work this time .


Thanks

no pro, you are welcome.
