Dissecting a uRamdisk

In update packages, ramdisk.img is renamed to /boot/uRamdisk.

   1 # Skip 64-byte header
   2 dd if=ramdisk.img bs=64 skip=1 of=ramdisk.gz
   3 # Uncompress
   4 gunzip ramdisk.gz
   5 # Extract
   6 mkdir ramdisk
   7 cd ramdisk
   8 cpio -iv < ../ramdisk

Once modifications are made, you can recreate the image:

   1 find . -regex "./.*"| cpio -ov -H newc | gzip > ../ramdisk.gz
   2 mkimage  -A ARM -T RAMDisk -n Image -d ../ramdisk.gz ../uRamdisk

Source: xda-developers - View Single Post - NT: Build root filesystem, which also describes recreating the ramdisk image.

Circumventing Barnes & Noble DRM for EPUB provides ignoblekey.py, ignoblekeygen.py, and ignobleepub.py

Barebones Cyanogenmod describes what programs/APKs included by default w/ the ROM you can delete. E.g. phone dialer, messaging, etc.

Some I think are unncessary for the Nook:

adb remount
adb shell
cd /system/app
rm Mms.apk
rm VoiceDialer.apk

V6 supercharger modifies Android's default OOM killer settings. Supposedly manages RAM better? Recommended for the Nook: Option 9 (MegaRAM 2 w/512mb {6,12,75,100,125,150 mb}).

[ROM][CM7.2-RC0] MiRaGe - KANG build of CyanogenMod - xda-developers is a build of Cyanogenmod 7.2 w/ Roboto as a system font, upgraded low-memory use kernel, etc.
