Upgrading NITDroid N11 “Vostok” to N12 “UMay”?

Incredibly there is a new version of NITDroid available. It’s named “UMay” and is version N12. It is clear Alex Roslyakov (@drunkdebugger | e-yes) has a lot of passion for this project and it shows in his timely updates.

Looking at my site statistics I can see lots of people are interested in my “How to install NITDroid N11 “Vostok” on N900?” post, so I aim to show you that it’s not a big deal upgrading to  the new version if you already have N11 “Vostok” installed.
PREREQUISITES:

1. Download the 64MB image N12_UMay.tar.bz2 from Megaupload mirror site. The file can also be downloaded from http://downloads.nitdroid.com/e-yes/N12_UMay.tar.bz2, but I found the MegaUpload mirror to be quicker. (Thanks to debernardis for this upload).
2. As I already have the Nitdroid kernel installed from Version N11, I have not re-installed it.
3. Copy N12_UMay.tar.bz2 to /home/user/MyDocs folder on Nokia N900. I use WinSCP to copy the files from my computer to the /home/user/MyDocs folder.

UPGRADING N11 “Vostok” to N12 “UMay” to EMMC:

1. Load X-terminal or PUTTY and type the following:
   Note: When running the ‘bzip2 -d N12_UMay.tar.bz2′ command there will be a bit of a delay while the file is extracted. This is normal.

1 2 3 4 5 6 7

sudo gainroot cd /home/user/MyDocs bzip2 -d N12_UMay.tar.bz2 cd / mount /home /and cd /and tar xvf /home/user/MyDocs/N12_UMay.tar

2. Exit out of X-terminal or PUTTY, reboot your Nokia N900 and on startup one is presented with a boot menu. Type ‘2’ for NITDroid 2.6.28.NIT.06 and it should load up.

NOTE: The first time Nitdroid boots up it take a long time (+- 3 minutes of waiting at the Nitdroid logo), before one sees anything resembling Android. The second and subsequent start ups into Nitdroid are fast.
