Blackrose is a powerful software. It can do a lot of things, but its most useful ability is to resize internal storage. On Nexus One you have to do so in order to install ROMs with greater size as… Ice Cream Sandwich (I’m preparing a guide).
Disclaimer
I AM NOT RESPONSIBLE IF YOU BRICK / RUIN YOUR PHONE IN ANY WAY.
BASIC COMPUTER SKILLS REQUIRED.
PROCEED WITH CAUTION.
Installing is safe, but using Blackrose can wipe out all your data. Proceed at your own risk. Make sure you backup all your data before proceeding.
Prerequisites (my situation)
pc with Ubuntu Linux 12.04 64bit
adb installed and working
USB cable
Nexus One data:
rooted device (probably not necessary)
ClockworkMod recovery installed (probably not necessary)
unlocked bootloader
HBOOT-0.35.0017 (other hboot are supported, see documentation)
run Blackrose (package contains an executable binary for GNU/Linux) cd blackrose_120421
chmod +x Blackrose
./Blackrose
Example output
First use (installation) -------------------------------
| Nexus One BlackRose 120421 |
| Made by Lecahel(XDA-dla5244) |
| Dok-Do belongs to KOREA |
-------------------------------
Do at your own risk
Don't flash any unsigned radio image
Don't flash eclair rom(eg.EPF30), if you are SLCD Nexus One user
If you are using sense rom, please install HTC Sync and turn off that now
Your N1(USB Debugging ON) should be connected to PC
If your device has already installed latest BlackRose, it will enter into BlackRose menu
Otherwise, BlackRose will be installed or updated automatically

Please make a decision:
When you download a Raspmc (Raspberry Pi Media Center) image it’s a .zip file.
If you want to check the content of the file you must find a way to mount the image.
Prerequisites
a pc with GNU/Linux
a user with root permissions on the pc
the image you want to analyze (download from the site)
Procedure
first of all unzip the archive$ unzip installer.zip
you’ll notice one file: installer.img that’s an image of a block device:$ file installer.img
installer.img: x86 boot sector; partition 1: ID=0xc, starthead 0, startsector 2048, 131072 sectors; partition 2: ID=0x83, starthead 3, startsector 133120, 251904 sectors, code offset 0xb8
create a mount point$ mkdir /tmp/mnt-installer
if your “file” output gives you less informations, you can examine the image structure (sizes in Sectors) with the following command$ sfdisk -uS -l installer.img
Disk installer.img: cannot get geometry
Disk installer.img: 24 cylinders, 255 heads, 63 sectors/track
Warning: The partition table looks like it was made
for C/H/S=*/4/32 (instead of 24/255/63).
For this listing I'll assume that geometry.
Units = sectors of 512 bytes, counting from 0
Device Boot Start End #sectors Id System
installer.img1 2048 133119 131072 c W95 FAT32 (LBA) installer.img2 133120 385023 251904 83 Linux
installer.img3 0 - 0 0 Empty
installer.img4 0 - 0 0 Empty
take a note of what you want to mount, i.e. img2 (Linux filesystem) as I highlighted
with root permissions, mount the desired partition on the previous created path (133120 is the Start sector taken from the last output)$ sudo mount -o loop,offset=$(( 512 * 133120)) installer.img /tmp/mnt-installer
check the content$ ls -lAtr /tmp/mnt-installer
total 96

Please double check the requirements I wrote before you proceed and remember that:
I am not responsible if you brick / ruin your phone in any way;
some computer skills are required;
do a full backup of your data NOW, it’s not programmed, but you may loose them
Software requirements
CWMInstaller-Linux-v4.zip: download from here or from my mirror.
Do some backup before changing things
On your pc: adb shell
on the device # su
# mount -o remount,rw /dev/block/mtdblock0 /system
# cat /system/bin/chargemon > /system/bin/chargemon.original-backup
It’s time to get the job done
The package is done to allow anyone to easily install the whole thing, but I wasn’t able to use the script.
You can see what I did to manually achieve the result.
On your pc $ unzip CWMInstaller-Linux-v4.zip
$ cd CWMInstaller-Linux/
$ adb push files/ /data/local/tmp
When booting your phone and when the “Sony Ericsson” letters appear (not the logo), press and release continuously the “back” button.
Once you are in the CW recovery, use the volume keys to navigate upwards / downwards, the “home” or “camera” button to select, the “back” button to go back.
Go to “backup and restore“, “backup” and wait at least 3 minutes (on an empty device).
Conclusions
Now you are ready to install some new ROMs on your device.
