Hacking Downgrade to 1.0E with profi200's sysupdater failed

[Nyap]

I'm trying to downgrade an emunand to 1.0.0.0E using the files that @MassExplosion213 gave me but the downgrade fails at "0004001000022000.cia"
I'm using this sysUpdater: https://github.com/profi200/sysUpdater/releases

titleException:
title.cpp:126: Result: 0xD8E08027
Failed to finish CIA installation!

From what emunand version are you downgrading?

 

[Nyap]

From what emunand version are you downgrading from?

latest
I think they blocked downgrading on this version, but apparently CFW is unaffected

Not every CFW patches that. I'm sure Luma does, though.

yup using luma

 

[SomeGamer]

yup using luma

Then I'm out of ideas, sorry. Still, watching this thread!

 

[Nyap]

any other info I should provide? :/
I can still enter the home menu... In fact, FBI has been replaced by the normal Health and Safety Information app, so that must have suceeded xD

Do you have the 10.7 firmware.bin? Make sure to deselect "SysNAND is updated" if you're downgrading emunand.

 

[Townsperson]

If you have a <11.0 backup, flash that and then downgrade.

Yeah i'm 100% sure i'm in emunand

Do you have the 10.7 firmware.bin?

I'm not sure

I don't, but CFW should fix the downgrade patch in 11.0

--------------------- MERGED ---------------------------

- rebooting still works
- system settings is gone

--------------------- MERGED ---------------------------

I think I bricked emunand I tried deleting the file that was causing the error, but then the next file caused the same error and after rebooting I just get a black screen

Is there a way I could get my hand on the 1.0.0.0E files?

Btw. What are you doing with the 1.0 EmuNAND then? Flash it to sysNAND?

yup, I'm going to flash it to sysnand and try and use it with cakesfw (using no patches)
I got the files from @MassExplosion213 if you want to ask him for them, I could also upload it to that iso site but I'm not sure if he'd approve of that
He also has 1.0.0.0U files

also, I've deleted all the files starting with 00040010 and I'm going to try downgrading again

 

[astronautlevel]

Did you make sure what I said about checking the Luma options was correct?

 

[BabyBichu]

Maybe u could unbrick ur EMUNAND using OTPHelper

 

[astronautlevel]

The downgrade failed. That won't help

 

[BabyBichu]

The downgrade failed. That won't help

Okay just a guess.Thank u for telling me about it.
I thought if it works he could launch sysupdater from EMUNAND to continue downgrading again

There's no point in downgrading to 1.0.0, no CFW can boot that

 

[Nyap]

I'll try downgrading again using all of the cia files, and every time a cia fails to install i'll open up FBI, go to the updates folder and delete it

There's no point in downgrading to 1.0.0, no CFW can boot that

CakesFW with no patches might

note: i'll have to do it after school

 

[GBHAKC75]

CakesFW with no patches might

Where did you read that ? Cakes can't boot 1.0.

 

[Nyap]

Where did you read that ? Cakes can't boot 1.0.

Is there a way to boot sysnand without cfw on a9lh? and if not, what would I need to get it to boot?
