Fan keeps blowing after Trinity shut off. Only happens when using FSD

Recommended Posts

XBOX Slim Trinity

Dashboard : 2.0.16547, latest Xebuild and Dashlaunch (through Jrunner).

FSD F3 rev775.

Have now encountered this behaviour on 3 Trinity XBOXes (2 at my shop, one at a colleague's).

Symptom : after glitching the XBOX (using latest jrunner) and flashing Xebuild nand everything works fine. Can go into Xell and shut it off with power button, no problem. Can get into Xebuild dash (2.0.16547) and all is well as well, can shut it off with power button without problems.

Then FSD is put onto the internal HDD. Once rebooted FSD is entered without problems, can play for hours, XBLA,  full games, the works. 

When it's time to shut it off, it doesn't matter if it's done via a push on the actual poweroff button or via the menu, the XBOX will keep its fan going and the green led on the powerbutton will keep pulsing. This will go on forever, even after 45 minutes. I know there is a cooldown period but this is usually around 10-30 seconds. 

This is not a fluke. It happens EVERY time when the XBOX is turned off (or at least when that is attempted).

Only remedy is to tap the power button twice and then keep it pressed until the XBOX turns off (actually a forced shutdown).

Apart from this not being a fluke in this particular XBOX, it can be reproduced with every Trinity I get here (or at the colleagues site). 

Fun fact, when FSD is removed from the HDD the shutdown procedure works as it should.

Have tried the following :

- reflash with the same updflash.bin (via Xell AND via SPI programmer) : no luck

- create clean nand in jrunner to rule out smc config problems, then use that as basis to create new Xebuild version. Flash that to the xbox : no luck

- run FSD from USB : no luck

Things to be noted :

- there were no bad blocks 

- it never happens with Corona motherboards

- I don't recall this happening on dashboards < 2.0.16537

- It's not just me. It's no installation error. Everything works fine as long as FSD is not installed.

 

Hope someone can acknowledge this behaviour and/or even offer a fix for it, because this is extremely annoying.

Try this:

 

Go to NXE, system settings startup/shutdown

There is a setting to allow background downloads after shutdown. Set it to "Off".

Xbox should now shutdown immediate.

Ok, the plot thickens. Had another Trinity to do today. Fully expecting it to do the same thing I turned the XBOX off while in FSD... and it just turned off  :huh:

As per your suggestion I checked the background downloads setting.. and it was enabled. So.. that's not it. And more so, it doesn't happen to ALL Trinities  :veryangry:, which does not help the troubleshooting.

Nexus said if the background download setting was enabled to disable it. Have you disabled the setting? Another thing that can cause symptoms like this, is if you have a play and charge kit plugged into your controller. Usually double tapping the power button quickly will shut it down.

Hi, i was loking for info about this problem, the console would turn on/off properly if i booted into xell, or if i turned it on and off before it glitched. After the glitch i pressed power and fans kept spinning and the power brick led stayed green. After that i would click power once and the glitcher started to blink, but the center led (console power led) stayed off. Very strange, it would only shut down after another power button click.

After reading this i unpluged the play and charge kit and it's working just as expected. I wount even try to guess why, but the play and charge causes this to happen, not the dashboard.

It's a bit of both actually, there's a setting in the dashboard which says to have background downloads, this in itself can cause the problem...
