I downgrade my switch to 6.2 today from 7.0 and when I boot into ReiNX, everytime it go to sleep it go into rcm mode instead. Already try the latest ReiNX but it still not work. Any idea why?

Iirc, Reinx still has sleep bug when you have more fuses than your FW needs or at least your version of reinx has it or I don't know.I downgrade my switch to 6.2 today from 7.0 and when I boot into ReiNX, everytime it go to sleep it go into rcm mode instead.

Ah, I thought they already fix that. Anyway to run pirate rom on atmosphere?Iirc, Reinx still has sleep bug when you have more fuses than your FW needs (or at least your version of reinx has it).

I don't know. If it was fixed, I am obviously totaly wrong. And yes, there are sigpatches for 7.0.0/1 now.Ah, I thought they already fix that. Anyway to run pirate rom on atmosphere?

If you downgraded, that means you have AutoRCM activated. There is no getting around this issue for now aside from using Atmosphere. Also take a look at this.I downgrade my switch to 6.2 today from 7.0 and when I boot into ReiNX, everytime it go to sleep it go into rcm mode instead.

It sounds like you are using an outdated version of ReiNX on your SD card and/or as your payload since ReiNX fixed the warmboot issue as of V2.0 if you check the changelog.I downgrade my switch to 6.2 today from 7.0 and when I boot into ReiNX, everytime it go to sleep it go into rcm mode instead.

Update your ReiNX. The latest version is 2.4had this been solved already? i've been facing the same issue for months now but I can't seem to find the solution for me. my switch is running v7 ofw with reinx 2.2 as cfw

This is a thread from February. Around that time, only Atmosphere supported firmware 7.0. Neither ReiNX nor SX OS supported that firmware. So if you wanted to boot those CFW but did not want to wait for the next release, downgrading was your next logical step.Why would you want to downgrade your switch at this point? 7.0.1 is the recommend fw.
This was actually addressed to DxDyzzz who answered yesterday and stated he had the same problem, somehow I didnt see that he already is on 7.0.1 and thought he was also at 6.2, my bad.This is a thread from February.
