this kernel is patched with titans patchs and is overclock enabled if anyone feels adventourous enough to copy the required filess of their maemo partition to the microsd to try this let me know

requirements

1. knowledge of how to flash your device
2. my android rootfs: http://files2.nitdroid.com/nitdroid-....0.1-demo.tbz2
3. my kernel image: http://files2.nitdroid.com/zimage-nitdroid-0.0.1
4. 1 microsd card (i'd say min of 1gb, this how-to will show the layout for my 8gb)
5. some idea how to edit files and run commands via a terminal
6. linux based pc/vm
7. (optional but recommended) some sort of ssh server installed in maemo5

how-to:
1. Grab the required files from above.
2. Login to your n900 as root (either xterminal or over ssh (ssh is easier) ) and run the command below:

Code:

sysinfo-tool -g /certs/npc/esn/bt_id

keep a note of the value it returns as you need it further on in this howto
3. Mount your microsd via either n900s usb storage or direct via a card reader (probably faster to do latter) then find out the device node assigned to it on you linux system (dmesg will give you easily enough) then run the following (/dev/sdb is the node the microsd shows as on my system):

Code:

fdisk /dev/sdb
o
n
p
1
<press return>
+2g
t
c
n
p
2
<press enter>
<press enter>
w
q

this should correctly partition your microsd for the next stage
4. Now create filesystems,

Code:

mkdosfs /dev/sdb1
mke2fs -j /dev/sdb2 -m0

5. Once those have ran mount the ext3 partition

Code:

mount /dev/sdb2 /mnt

6. Now navigate to that folder and extract the rootfs (i hope you saved it somewhere you can remember )

Code:

cd /mnt
tar xjvvpf ../nitdroid-n900-0.0.1-demo.tbz2

7. Wait patiently for the extract to complete (it takes some time)
8. Once the extraction has completed navigate to the system/bin folder and open the load_modules.sh file in your favourite editor (i use nano)

Code:

cd /mnt/system/bin
nano load_modules.sh

9. Scroll down the file and find the line that starts
echo 0cddef0a0e6d and replace the 0cddef0a0e6d with the text you wrote down in step 2 - this is to enable the bluetooth module to work. Once that is done save and close the file then you can unmount the microsd

Code:

umount /mnt

10. Insert the microsd into your n900 and then power down the device (disconnect charger etc before hand.)
11. Boot your n900 into 'flash' mode (hold u on keyboard as you connect usb cable)
12. Run the following command to flash the kernel to your device

Code:

flasher-3.5 --set-rd-flags=no-ext-wd,no-lifeguard-reset --enable-rd-mode -f -k zimage-nitdroid-0.0.1 -r

adjust the zimage part to give the path to where you saved the file

the device should reboot and begin to start android.

The back cover must be in place or the system will crash
