Led Changer has been updated to version 1.1. Changelog below:

fixed the path that makes this HB Crash

That is right, deroad is back with another release for all of your Jailbroken PS3 consoles. Today, he introduces the world to Led Changer v1, and app that can be used to change the color of your system's LEDs (the power light). Be sure to take a closer look at this release, and then go out and experiment with your own PS3s.

This is a simple led changer.

this will change the led color and if it is on mode on/off/blink and it will keep it on that mode also on the XMB
for example now my ps3 has green and yellow together while blinking

README

Code:

Written by deroad

this is a simple led changer
it reads two var (A and B) from a file.

the file must be called led.txt and placed in the main folder of a USB
an example:


on Windows:

My USB is j so, i will put this file here:
j:/led.txt

on OSX:

My USB is 8GB so, i will put this file here:
/Volumes/8GB/led.txt

on LINUX:

My USB is 8GB so, i will put this file here:
/media/8GB/led.txt

======Colors=======

A	Desc		B	desc

0	red		0	off
1	green		1	on
2	yellow	2	blink

I was just thinking the opposite. Finally a fix for the YLOD.

you're twisted. It'd be cool if you could blank the screen and lock the controls and disable the power/reset buttons too. That'd really freak someone out. But all BS aside, I don't see the point. It'd be cool if the led changer and the beep mod that he did could work when you first boot up and play some killer guitar riff in the ps3's system beeps with the led flashing with the beat. But this is just a package right? I take it that it's not a permanent mod - that it would stop functioning when you exit or turn off your ps3. I'm not gonna install either one of these. Please correct me if I'm wrong or I'm missing something

Now I can really see if that red light is really broken or just being gay (not that there's anything wrong with that)

Nice work! This looks very interesting and promising, but I have a few questions. What are the LEDs controlled by? Aren't they controlled by the SysCon? If so, since when are we able to talk to the SysCon? If this app communicates with the SysCon, then this is a big step ahead. Could you please try to make an app, which regulates the fan speed and monitors the system temperatures? That would be freakin' awesome. Thanks in advance.

yes, Leds and Beeps are controlled by SC.
but there are some syscalls that allow it also in gameos. this should work also on unmodifyied fw.

Thank you for the quick reply! I assume the GameOS "instructs" the SysCon to manipulate with the LEDs and the speaker when you call those SysCalls, right? So would a fan speed regulating app be possible at all? Are there any SysCalls for that? Or is it necessary to decrypt the SysCon firmware and modifiy it to achieve this? Thank you.

unfortunately, some syscalls require special modes. for the fan policy, there is a syscall that do that, but it can be called only on service mode.
same thing for the syscall they say the temperature of the PS3.

(i already tried them, because i was curious)

Have you tried it with the QA flag enabled? Or on Rebug firmware with debug mode on?

yes, i have the QA.
also tryied on rebug. that syscall works only in service mode.

Ok, thank you. So I assume the only way to mess with the fan speed would be to decrypt the SysCon FW and patch it or to come up with a CFW (or MFW task) that allows those SysCalls in normal mode. And what about the lv1/lv2 peek/poke calls, can't they help? You know, by patching the kernel/HV memory.
Oh hell, I wish I would know how to create a CFW or MFW task and I could do something about it. I'd really love this feature. But I hope so that one day we will have ABSOLUTE control over our PS3s. Thank you, deroad and all the other devs and keep up the good work.

well if someone will find the encryption key of the sc fw, i will be the first to mod it.
lv1 peek/poke are useless since we can use the lv1 unmapped function 114
yes, we can dump the sc eeeprom.
there is already an hb that allow it. you can find it on the wiki

what? on your ps3 it doesn't work?
i have just fats, so i tested it on these models. i'm on 3.55 on both and i have only peek and poke + mmap114 patches.

you are on?
tell me so i can try to fix it.

I'm on Rebug 3.55.2 and on a non-BC 40gb Phat Console. i install the pkg and run it and it just changes resolution to 720p and just sits at black screen until i force my PS3 to shutdown

have you read the readme? you need to put inside a usb a txt file called led.txt with the values.
it can crash if you do not use HD TVs.
This is the SD version.

I have a 42 inch sharp aquos Full 1080P HDTV using HDMI from the PS3 and i used the led.txt file that came with the pkg. I even changed it to include just the number 0 to see if anything changed and the same result. Also i know it changes to 720P because my TV notifies me in the top right corner to show resolution changes.
