Question Softkeys don't light-up, Trackball flash red (Error?!)

After i go step by step this tutorial the softkeys on my Nexus One don't light-up. If it is dark, in example by night, i didn't see the keys and i have to guess where the right softkey is.

I think the trackball flashes red, because it's a error statement that the softkeys are faulty.

I think the problem made by flashing the mtd0.img from this website , because it's for a HTC Desire.

So i think i have to flash the right mtd0.img for a Nexus One LCD to fix the Problem.

But i can't find something like this.

After this procedure the display don't work and i flashed the PASSIMG_Passion_Google_WWE_2.16.1700.1_FRG33_relea with the new HBOOT for my LCD on my Phone. Then i flashed CyanogenMod 6 stable and it still works fine, but the softkeys always dark and the trackball flash red.

If the room bright enough, and the softkeys has not to flash, the trackball doesn't flash red.

So i need help, please.

Sorry for my english, it's not my native language.

FYI, this should not be in the development forum... mods please move!!!

Trackball flashing does not mean error... it's a notification alert... and as to the soft-keys... they don't flash... they lightup... maybe something to do with the SLCD version of the N1!!!

Do they light up if you have just stock??

First time, before i downgrade my hboot the softkeys light up. Now, after downgrade and upgrad back to 0.35.0017 they don't light up.

There is no difference between stock or custom rom.
I tested:
- PASSIMG_Passion_KT_KR_2.15.1010.2_FRF91_release_si
- PASSIMG_Passion_Vodafone_Generic_2.15.151.5_R_FRF
- PASSIMG_Passion_Google_WWE_2.16.1700.1_FRG33_relea

After i flashed Google_WWE_2.16.1700.1_FRG33, flashed CyanogenMod with Custom Recovery (RA-nexus-v1.8.0.1-aw).

For what does the notification stand? It's also red, if i flashed a stock rom and has no additional apps installed.

When i put the lightness sensor under a lamp or is bright enough (sun is shining), the trackball doesn't flash red.

If the phone is in standby, the trackball doesn't flash.

Sounds like a sensor calibration failure.
Is there any data files stored anywhere in relation with hboot.
Your flashing procedure for 0.35 hboot retrieving may not put the LCD compliant data's.
Sorry it's only a clue, I'm novice in android and nexus.

Thank you for your comment, but until now I didn't have an idea how its help me.


Until now I'm not possible to fix the problem.
I only found a way to disable the red trackball:
I go to CM settings under "user interface" and activated "use custom" in "automatic backlight" and set in "edit other levels" all levels to 0 at buttons. So the system will not activate the back-light of the soft-keys in any way and the error message (red trackball) don't appear.

Additional i know that the back-light is not faulty, when i started in LED notification the flash test in someone of the application, the back-light lights up collectively with the trackball.

The problem is still alive, when i have a stock rom, like Passion_Google_WWE_2.16.1700.1_FRG33.

Have anyone another idea how i can fix this problem?
