Some instructions here may cause serious problems. When unsure, see General precautions Backing up your data is recommended. In case of trouble you might need to re-flash your device.

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.

1. Download the NITDroid Autoinstaller to ./MyDocs i.e. root directory of N900 and install it:

2. Run the NITDroid installer app from your programs list.

(If installation fails, try writing apt-get install bzip2 in XTerminal)

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:
   • Image: http://downloads.nitdroid.com/e-yes/
   • Kernel: http://downloads.nitdroid.com/e-yes/nitdroid-kernel-2.6.28-07_rc4_armel.deb
   • Fdisk: http://ftp.de.debian.org/debian-archive/debian/pool/main/u/util-linux/util-linux_2.13.1.1-1_armel.deb
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. Ignore any errors. 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
   umount /dev/mmcblk0p1
   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
    

    
    

11. Trouble Booting NITDroid

    If you cannot boot into NITDroid because of an error like this one:

    "Root Filesystem mmcblk1p5 missing" Guru Meditation 0000025...etc

    
    Try following:

    Edit /etc/multiboot.d/11-NITDroid-mmcblk0p5-*.item with an editor of your choice (eg. nano).

    apt-get install nano
    nano /etc/multiboot.d/11-NITDroid-mmcblk0p5-2.6.28.NIT.07.item  #check filename!
    

    And change the line ITEM_DEVICE={INT_CARD}p5 to:

    ITEM_DEVICE=mmcblk0p5
    

    reboot with opened keyboard and try to start NITDroid.

Uninstalling NITDroid

Method 1

Tap on the NITDroid-Uninstaller on your menu.

Method 2

Open X Terminal and type the following commands:

root
mount -o noatime,rw /dev/mmcblk0p5
rm -rf /and/.

Then uninstall multiboot by anyway you prefer.
