Loccy, here are the results:

try flashing this
FR-9-K-DE12RD-FR-fixed_S.zip

its for Kings Droid Eris but it should work fine with Legend

this did not work on your Vega Cache Hack, just an fyi, freezes at g1 screen

yeap, because the ramdisk dosn't mount the /cache correctly

give us a few min, I upload a CH compatible one

ref stat

your just comparing file size?

try using

Code:

if [ "`du ${target1}|cut -f1`" = "`du ${target2}|cut -f1` ];
then
     do sumat
else
     sumat else
fi

you might need to set the field for cut, default is tab
busybox du is usually tab delimited, but you could test output and set the du command accordingly

Not true, this does work. You can just punch in the commands on page 1 in Terminal after flashing, thanks FR, you made this easy. This "cheat" for the lights in general seems to glitch a bit but it works!

AND works after reboot, to confirm. I'm running Kings Droid2eris 1.2 with FR apps2sd and speedy 3d kernel.

yeah, second boot would probably fix it

the script doesn't make its log directory, so it fails
but before doing so it creates the directory, so next time round it works

not checked what you currently have,

but personally if the files are small, I would just create a directory on the tmpfs ( /dev/ )
it will be very fast, as its a ramdrive
obviously don't dump too much on it, as it will eat memory, but a no one will notice a few k

This is what I got....

Code:

$ export PATH=/data/local/bin:$PATH
$su
# sh /system/bin/lightbodge.sh &
sh: Can't open /system/bin/lightbodge.sh
[1]   Done(2)                 sh /system/bin/lightbodge.sh

Thanks Loccy and Firerat. That backlight script works like a charm. I have keyboad backlights now!! The only bad thing is it got fixed after I found Swype and only use the physical kb rarely now. Oh well. I still like having the option.

thanks for the thanks, but nothing to do with me

Still not clear if this works on Vega's 0.91

Firerat said:

I run Vega's 0.91 Legend with his YouTube patch applied and Firerat's King's #8 Kernel and Wi-Fi fix patch and am quite happy with that setup (although I lost 3D with the King's #8 Kernel).

Can I apply Firerat's King's 3D Kernel patch which first appeared in this thread (the original version, not this latest Cache Hacked version) successfully to Vega's v0.91?

Please let me know if anyone has tried this..

Thank you all!

UPDATE: ASKED AND ANSWERED - Tried to apply it and it hung at the G1 screen. Reverted back to Vega 0.91 applied Vega's YouTube Patch and FR King's #8 Kernel and Wi-Fi patch.

Hello Firerat. Here's an update on your FR-FR9-Legend-CHRD_S.zip. Definitely, runs faster on FR-King-Legend10-CachePatch, but keyboard light is still not op. Lost wifi, too. WiFi is unable to start.

Thanks for your prescience in all of this. What tremendous resourse to the forum you are.

Hi all

I added Loccy's script to my latest Vega's Legend CacheHack

my ramdisks init.rc is launching /system/patch on boot

I made a few changes,
replaced the stat cmd with du
changed the log location to the tmpfs ( /dev/ )

its working great, out of the box

here is a diff patch

its over at Vega's Legend Thread
post #1329

TheDeadWalk · Apr 17, 2010

I got mine working by following intructions on first post.
then, i went into terminal emulator and entered this

su
sh /system/bin/lightbodge.sh &

that got it working

a bit sluggish but still working!

EDIT: they seem to turn on randomly when not even touching the phone.
any idea how to fix this?

senab · Apr 17, 2010

I've fixed HeroLED for Eclair Hero. I've added a few features so far, the biggest being that it automatically turns on the keyboard backlights when open, and Sapphire/MT3g support.

keyboard backlight issue alternative solution

I have found an alternative simple solution for the keyboard backlight issue on android:

prerequisites:
root access
busybox (possibly)

The trick is to read from the input device related to the keyboard and turn the light on when any key is pressed.
you have to create a shell script called for sample backlight.sh with these instructions:

Code:

while [ 1 ]
do 
  cat /dev/input/event3|read -n 4
  echo "1"> /sys/class/leds/keyboard-backlight/brightness
  sleep 1
done

copy it on sdcard and try to launch it as root from a terminal emulator:

If you don't want the script has bound to the controlling terminal launch it with:

Code:

nohup bash /sdcard/backlight.sh > /dev/null &

now when you press any key on the keyboard it would light up!

write a feedback please!

sUsH667 · Aug 8, 2011

i've read from the first page til here and have one question:

this keeps my keyboard's backlight switched on as long as the keyboard is opened and switches it off if i close keyboard, is that correct? or will the keyboard's backlight dim off after few seconds?

greetz,
