Question: Does Auto-RCM get reverted upon a HOS Update?

[Aetopia]

I recently updated atmosphere & and my Nintendo Switch to (13.2.1). The Auto-RCM that was enabled on 13.2 is now gone.

I wanted to ask if updating HOS repatches Boot Files on the Nintendo Switch?

When a system update is completed while stock firmware is running, AutoRCM becomes disabled so you need to turn it on again

Thanks! I was wondering I could prevent this by updating HOS in a CFW.

You can prevent it only by using homebrew updaters like Daybrake.

Updating on sysCFW will preserve auto-rcm and fuses.

...i think you have to reconsider what you have just said...

Then are my consoles broken somehow. None of them had a disabled autorcm after an update.

Where did I go wrong?

If you have autoRCM enabled and you're updating your system while in stock firmware, updating will disable autoRCM and you will need to enter RCM manually to boot custom firmware again. To prevent autoRCM from being disabled, boot CFW on sysMMC and update through settings from there, as booting without AutoRCM will burn any preserved fuses.

hm, actually yes, you are right... This feature was implemented into atmos not long ago and i completely missed it... i think it was during the release of daybreak or somewhere close to that time. Before that you couldn't preserve autoRCM using "settings" updater even if you was on cfw sysMMC. You could only do that using choi back then.

p.s. clarified that in retro-nx discord

Yes, Atmosphere prevents AutoRCM from being overwritten during system updates.
