Installing NITDroid

This tutorial is specifically designed to install Nitdroid on the internal memory of the N900 (EMMC) and does not apply to installation on an external micro SD card. The main purpose of installing Nitdroid on the internal memory is that in most cases you will see an increased performance.

There are two ways of installing NITDroid:

1. Copy NITDroid's rootfs to /and in /home: Easier - Faster

2. Creating a custom 2GB partition on your eMMC: Cleaner - Requires a brain


Method 1

NOTE: It is highly recomended that you flash the modded 8GB 20GB eMMC image. Nitdroid won't recognize/use/install anything if you have low memory in mmcblk0p2.

Clean Installing of NITDroid

  1. Download the archive + the kernel to /MyDocs i.e. root dir. of N900:
  2. Enable all repositories from App manager (Extras-testing, Extras-devel, Extras and the default Nokia repos)
  1. Install Leafpad from the App manager and make sure that you have root access
  2. Close App manager, open X Terminal and execute the following commands: 
    root
apt-get update
apt-get install nitdroid-installer
y
y again if it asks again.
  3. After the nitdroid-installer package is installed, close X Terminal, but do NOT run the installer you have just downloaded.
  4. Open X Terminal, and execute the following commands: 
    root
cd /home/user/MyDocs
bzip2 -d nitdroidarchivename.tar.bz2

    (You can only uncompress the file once. So only do this step once!)

  5. Open X Terminal (or use the same xterm as you used for the previous step), and execute the following commands: 
    cd /home
mkdir /and
cd /
mount /home /and
cd /and
tar xvf /home/user/MyDocs/nitdroidarchivename.tar
dpkg -i /home/user/MyDocs/nitdroid-kernel-2.6.28-07_rc4_armel.deb
  6. Edit the boot file: 
    leafpad /etc/multiboot.d/11-NITDroid-mmcblk0p2-2.6.28.NIT.06.item

    (then tap the tab button, .item file will show, hit enter to open it in Leafpad).

    Edit ITEM_DEVICE in the file according to this:

    • If you have an MMC (micro SD card) plugged in your N900, change ITEM_DEVICE to this: 
      ITEM_DEVICE=${INT_CARD}p2
    • If you don't have an MMC plugged in your N900, change ITEM_DEVICE to this: 
      ITEM_DEVICE=mmcblk0p2
  7. Once editing is complete click the drop down menu on Leafpad and save then close Leafpad.
  8. Close X Terminal, reboot N900 and type ‘2’ for NITDroid.

    You can now start using Nitdroid

Upgrading from Previous Versions of NITDroid

Note: CLEAN INSTALL IS HIGHLY RECOMMENDED. You have been warned.

  1. Download the image + the kernel to /MyDocs i.e. root dir. of N900:
    Open X Terminal, and execute the following commands: 
    root
cd /home/user/MyDocs
bzip2 -d Nitdroidarchivename.tar.bz2
cd /
mount /home /and
cd /and
tar xvf /home/user/MyDocs/Nitdroidarchivename.tar
dpkg -i /home/user/MyDocs/nitdroid-kernel-2.6.28-07_rc4_armel.deb

Method 2

As said before, this requires a brain and a bit of concentration, follow step-by-step, and use some logic.

NOTE: This will wipe all of your data, please BACKUP necessary data first.

  1. Download the archive + the kernel + Fdisk to /MyDocs i.e. root dir. of N900:
  2. Enable all repositories from App manager (Extras-testing, Extras-devel, Extras and the default Nokia repos)
  1. Install Fdisk by executing the following commands in Xterminal: 
    root
mkdir -p /home/user/util-linux /home/user/bin
cp /home/user/MyDocs/util-linux_2.13.1.1-1_armel.deb /home/user/util-linux
cd /home/user/util-linux
dpkg-deb -x util-linux_2.13.1.1-1_armel.deb root
cp root/sbin/fdisk /home/user/bin/
cd ..
rm -rf util-linux
  2. Unmount designated partition (./MyDocs): 
    umount /home/user/MyDocs
  3. Launch Fdisk: 
    /home/user/bin/fdisk /dev/mmcblk0
  4. Print your current partition table: 
    p

    This table should show up: 

           Device Boot      Start         End      Blocks   Id  System
/dev/mmcblk0p1               2      884865    28315648    c  W95 FAT32 (LBA)
/dev/mmcblk0p2          884866      950401     2097152   83  Linux
/dev/mmcblk0p3          950402      974977      786432   82  Linux swap / Solaris
  5. Delete partition 1 (./MyDocs): 
    d
1
  6. Create new re-sized primary partition: 
    n
p
1
First cylinder: 2
Last cylinder: 800000
  7. Create new extended partition: 
    n
e
First cylinder: 800001
Last cylinder: 884865
n
First cylinder: 800001
Last cylinder: 884865
t
1
76
t
5
76
  8. Point of no return - writing the table and syncing: 
    w
reboot
  9. After the reboot, return ./MyDocs back and format the new NITDroid partition by executing these: 
    root
/home/user/bin/fdisk /dev/mmcblk0
t
1
0c
w
mkfs.vfat -F 32 /dev/mmcblk0p1
mke2fs -L NITDroid -j -m0 /dev/mmcblk0p5
reboot

    If your device still has a flash memory on it, then lift your shoulders up as the hard part is gone!

  10. Install Nitdroid on the new partition: 
    apt-get update
apt-get install nitdroid-installer
mkdir -p /and
mount -o noatime,rw /dev/mmcblk0p5 /and
cd /home/user/MyDocs
rm -rf /and/*
bzcat Nitdroidarchivename.tar.bz2 | tar xvC /and
dpkg -i nitdroid-kernel-2.6.28-07_rc4_armel.deb
reboot





Uninstalling NITDroid

Method 1

Open X Terminal and type the following commands: 

root
mount /dev/mmcblk0p2 /and -o noatime

After it completes, using filebox, delete nitdroid's installation folders and files that were copied to home: bin, data, dev, etc (symlink), initrd, lib (symlink), mnt, proc, sbin, sdcard, sys, system, tmp, usr,default.prop, init, init.nokia.rc, init.rc

Method 2

Open X Terminal and type the following commands: 

root

rm -rf /and/*

Then uninstall multiboot by anyway you prefer.
