[Galaxy S I9000 Android Development] neldar:
This modification is

ONLY

for firmwares with Android 2.2 (froyo)!

What is BackLightNotification?

The BackLightNotification mod converts the touchkey backlights into a notification led.

What is modified?

The BackLightNotification mod replaces the kernel by a modified kernel and it also replaces the lights.default.so in /system/lib/hw/.

In detail: This kernel includes my backlight notification patch and additionally built-in ext4 and tun modules. (For lagfix and vpn support.) The lights.s5pc110.so in /system/lib/hw/ enables android led notification via backlights. This mod does not include any modified app. To enable led/backlight notification for an app/function see the Q&A "How do i enable notification for ...?"

What other features are included with?

working recovery 2e (for unsigned/testsigned update.zips - also included in the noroot packages)

ext4 support

tun support (compiled in - no module)

What Galaxy S phones are supported?

The kernel in this thread is only for i9000 and i9000m (Bell Vibrant).

If you are searching for a kernel for your phone have look at this page: Supported phones by BLN (official list)

If your phone is not listed on that page, then you may ask someone who creates custom-kernels for that phone, whether she/he would like to include BLN. The patches are compatible to all already released Galaxy S phones.

Does this mod drain the battery?

No, that issue has already been fixed in the eclair build (in v0.9.8rc3).

Measurements on eclair showed, that an ongoing BLN increases battery consumption by 0,18% per hour. The average battery consumption without BLN is 1,04% per hour, so an ongoing BLN results in an overall battery consumption of 1,22% per hour. And by the way: ongoing NoLed results in an overall battery consumption of more than 9,5% per hour. Please see the Q&A "How much does this modification affect battery life?".

For more questions and answers have a look at the Q&A in the second post.
