[DEV][WIP] Enable init.d scripts and build.prop mods for Nook Tablet!

---

I take inspiration from this post to enable init.d scripting on stock rom! I think it need be tested, but work fine for me!

Disclaimer: This may cause a bootloop! I'm not responsable for any brick or damage.

Enable init.d

What is it:
Enable init.d permit run "autorun at boot" scripts, you can put in that folder your scripts (eg. ram and net optimization, load custom modules, etc.) and that will executed during boot.

Prerequisites:

1. Busybox Installed;
2. Root Explorer or similar software, otherwise you can do it manually from terminal.

Open Root Explorer, go to /system/ and mount the filesystem as R/W.
go in /system/etc/ and create a folder called "init.d" (without quotes), then set permissions as rwxr-xr-x.
Edit the file /system/bin/clrbootcount.sh and add at bottom:

bb=/system/xbin/busybox
if [ -f $bb ]; then
     /system/bin/logwrapper $bb run-parts /system/etc/init.d
else
     for i in $(ls /system/etc/init.d/*); do
          sh $1
     done
fi

Put your init.d scripts (someone here) and set the permissions to rw-r--r--.
Remount the /system/ as R/O.

build.prop mods

What is it:
build.prop is the main configuration file, where you can find settings about the LCD Density, the market fingerprint, etc.
With this mod you will able too power up your Nook Tablet and have a snappier and faster device with a stock rom.

Prerequisites:

• Root Explorer (or similar)
• build.prop file
• cold blood

Step 1: copy the attached file in your memory card (or internal storage)
Step 2: open Root Explorer, browse to /system folder and press the button "Mount R/W"
Step 3: rename your /system/build.prop as build.bak
Step 4: copy build.prop from your card to /system folder
Step 5: Long press on build.prop - permissions - set to Owner RW-Group R-Others R (or chmod 644 from shell)
Step 6: Remount the folder as R/O and reboot your device.

Another method is do the same with a terminal emulator or ADB. I don't tried yet but the commands shoud be good:
Step 1: on your pc open an adb shell or open your terminal emulator on the Nook;
Step 2: write

$ su
#  mount -o rw,remount /system
cp /system/build.prop /system/build.bak
cp /sdcard/build.prop /system/build.prop
reboot

Well, your device now should be more snappier

forgive my ignorance, but how can lowering the pixel density improve the screen output?

If you set a lower pixel density your will have smaller text and icons, that mean you will see more informations in one page.
If you want bigger text, push it up!

Sorry please delte post. Where is the easy build prop file?
Sorry was on my nook and simple did not see it glaring at me at the bottom.

Couldn't be achieved also using lcdDensity from Market ?

Changing LCD density can make some games (Gameloft, I'm quite sure) not working. Just be careful.

Does anyone know the default wifi sleep policy, I want it to never sleep.
I would like to know because Im guessing that the wifi part is were you can change it since the advanced menu is missing under wifi settings
thanks

If you are rooted then you can access it under spare parts.

will changing lcd density allow greater access to apps on Market?

Can someone post what the modded build prop actually does? In another post it was SUPPOSED to allow greater access to market apps, but did absolutely nothing for me.
