Hacking Sigpatches for Atmosphere (Hekate, fss0, fusee & package3)

[bth]

v5 is out there now

changes nothing from v4 that matters, all it did was make the optional, by-default-disabled no-erpt patch which was brand new to sys-patch work correctly.

Is it possible to change the language in DBI?
I can't find it in the options

Please excuse me, but I am trying every combination with sig and sys. It keeps looping “please wait.” In airplane mode, however, they start. Is this normal? Where does this problem come from?

It seems i did something wrong. PLEASE HELP.
I installed FW 21.0.0 and the latest HATS pack from Sthetix.
I installed it to both SYSMMC-CGW & EMUMMC-CFW.
Obviously some apps are not working right and i changed my mind and i wanted to downgrade to 2.0.5.0.
I begun first with SYSMMC to downgrade the same way as upgrading via Daybreak. When i reboot to Hekate i choosed SYSMMC-CFW to see if it was ok but it won't boot and i am getting an error.
I rebooted the console and is booting normally from EMUMMC-CFW (but it is in 21.0.0 FW)
I want to go back to 2.0.5.0 on both SYSMMC & EMUMMC.
How can i fix it?

 

[josete2k]

3 options

Restore backup

Upgrade with tegraexplorer

Try the fix posted here (only tested on emummc)

You have never used Linkalho (or Haku33 or other tools for dumping certificates).

EDIT: I tried to unlink my account from Linkalho and IT WORKS!!!!!!!!!!

SOLVED: The “Please wait” loop has been resolved. Unlink my account from Linklho, even though I have never used it.
Everything works without having to reinstall anything. THANK YOU

could somebody help me fix sys-con mod for 21.0.0?

From my emummc (with fw 21.0) I accidentally launched a homebrew not updated to properly work on fw21+ and when I closed it I got an atmosphere error.
Now every time I try to boot on emummc I get this same error.
I tried to clean the micro SD card with a minimal atmosphere + hekate config but still the same error.
How screwed am I ?

if anyone with linkalho, on 21.0.0, that also cannot start games outside of airplane mode would like to test a new patch, all i need is feedback if the games now start outside of airplane mode.

the same can be accomplished with /atmosphere/config/system_settings.ini:

[olsc]
default_auto_upload_global_setting = u8!0x0

but i want to know if i cant just patch it through .ips (and then later add to sys-patch) so that users dont have to add new file to config folder, as bundles overwriting someone's custom settings is bad user experience


add to sd card, reboot, doesn't matter if fusee or hekate, as it's an exefs .ips patch

edit: updated atmosphere.zip due to missing byte in .ips patch

offset:
084F2C
size:
0004
patch:
1F0000F1 cmp x0, #0

original:
1F0400F1 cmp x0, #1

I can confirm adding that line to the atmosphere config allows me to play games with airplane mode off. It was the final issue I had after upgrade and it is now fully resolved, games that required a linked account launch without issue, without using airplane mode. Thank you from the bottom of my heart for all your hard work, seeing all the hard work here recently and having my baby purring has made my week.

Sigpatches updated for 20.5.0,

And Upgraded to Atmosphère 1.9.5

SYS-Patch should work fine with this FW.

They have already been released:

Updated patches pack for Atmosphère 1.10.0 (pre-release) and firmware 21.0.
With a big thanks to mrdude2478.

But I recommend using Sys-Patch instead

 

[Gr0vAtiRoN]

got someone hands on re-compiled versions of these or can do so?

need new compiled files:
-> pfbneo v6.7
-> nx activity log v1.5.7
-> MiiPort v0.1.1
-> HB App Store v2.3.2
-> GameCard Installer v2.0.0
-> EdiZon v3.1.0
-> Checkpoint v3.10.1
-> RetroArch v1.21.0

Hey, I'm a new user to CFW and right now I'm on 21.0 with the latest Atmosphere and sys-patch. Not sure where to post this but I'm having trouble accessing the web through the native web browser. I was wondering if there's any fix for that? Currently I'm using the hosts file from the Switch Hack guide and the custom DNS 192.168.1.13 (Primary) / 207.246.121.77 (Secondary), not sure if that's related. The error I get is "This feature is not available". Tested both on a game that asks me to accept Terms of Agreement and on Goldleaf's browser. Thanks in advance

Using sigpatch in #6108, not using syspatch.
For launching game without flight mode adds the following in /atmosphere/config/system_settings.ini:
[olsc]
default_auto_upload_global_setting = u8!0x0
