For your concideration: Getting around the locked bootloader and missing loop ko

This is my first post here, but I figured I'd share this since doesn't appear to have been done yet.
As I'm sure most of you know the locked bootloader introduces challenges to getting your favo(u)rite flavo(u)r of linux on to the Droid 2.
I expect that you have rooted your phone and have busybox installed/working...
Normally when one wants to do this they get a linux image file and mount it as a loop device and then chroot to it's mounted folder. Because one can create a loop device but can't mount it.
My solution has been a "simple" one but may not have been tried:
Extract the contents of the image on a separate system and then push everything to /data/local/mnt.
For instance I set up a loop device on Ubuntu:
losetup /dev/loop0 /home/usernamehere/distributionnamehere.img
mount -t ext2 /dev/loop0 /home/usernamehere/somemountfoldername​
Then I remove security stuff:
sudo chmod 777 /home/usernamehere/somemountfoldername
sudo adb shell
chmod 777 /data/local/mnt
exit
sudo adb push /home/usernamehere/somemountfoldername /data/local/mnt​
(Wait for the push to happen stop it when you see X11/X11/X11/X11 or remove that symbolic link before pushing. If you stop it you'll have to push the other folders separately)
After it's done the bootubuntu which points to that /data/local/mnt share (or /data/local/ubuntu or /data/local/debian or whatever) should throw a few errors about mounting which is expected because we haven't fixed the fact that loop devices aren't mountable, but since we pushed the files to the 'mount' directory, the script finds it anyways and chroots to the /data/local/mnt and runs /data/local/mnt/bin/bash (or /bin/bash from the chroot point of view.)
This will get you to the root prompt.
I'm still working on getting the bash: groups: message to go away, but I think that is just that I didn't get everything copied initially.
Also I have yet to finish setting up VNC.
Anyway I hope this helps some people out.
I may do a script or more complete instructions later if requested.
Thanks,
Sky Adams

Thanks, I've been stumped by this for awhile. Your method allowed me to push the files but my script still doesn't find it. I'm going to need you to post your bootubuntu script. I have an image from androidclone.com that has vnc setup already, just need to get it to execute.

Confirmed working on rooted Droid X. Used Lakia image from androidclone dot com
1) Partitioned 16GB SD: Shrink to 11.9 GB leaving ~4GB. Then create new ext3 partition in free space
2) mount ext3 partition and create the loop to the image as skrull mentioned above.
3) then just "[email protected]# cp -r pathtoloopiface/* pathto4gbmount/"
4) takes a while but preserves the symlinks to avoid the X11/X11/X11/ issue above. (I think the reason you were having problems with the bash at the end, was an incomplete adb transfer of the /usr folder and probably no /var transfer at all. At least that was the case when I tried.)
5) push and chmod 777 this bootubuntu script to /system/bin:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
export kit=/sdcard/ubuntu
export bin=/system/bin
export mnt=/data/local/mnt
export PATH=$bin:/usr/bin:/usr/sbin:/bin:$PATH
export TERM=linux
export HOME=/root
mount -t ext3 /dev/block/mmcblk0p2 $mnt
mount -t devpts devpts $mnt/dev/pts
mount -t proc proc $mnt/proc
mount -t sysfs sysfs $mnt/sys
sysctl -w net.ipv4.ip_forward=1
echo "Setting /etc/resolv.conf to Google Open DNS 8.8.8.8 and 8.8.4.4"
echo "nameserver 8.8.8.8" > $mnt/etc/resolv.conf
echo "nameserver 8.8.4.4" >> $mnt/etc/resolv.conf
echo "Setting localhost on /etc/hosts "
echo "127.0.0.1 localhost" > $mnt/etc/hosts
echo "READY TO ROCK AND ROLL BABY! "
echo "Brought to you by NexusOneHacks.net and the open source community! "

echo "Ubuntu 10.10 - Laika Edition by Androidclone.com "
echo "Website:http : / /www . androidclone . com"
echo "Email:[email protected] . com"
chroot $mnt /bin/bash
#After exit command is executed clear it all up
echo " "
echo "Shutting down Ubuntu"
umount $mnt/dev/pts
umount $mnt/proc
umount $mnt/sys
# the fuser command below allows us to kill all processes using the mount.
# otherwise umount will fail and the vnc session will still be alive.
# if it fails just run the fuser and umount again manualy.
fuser -k $mnt
umount $mnt
6) make sure there is a path to /data/local/mnt on the device and just run 'bootubuntu' from a root shell. you should get: "[email protected]/#:"
7) read the site on androidclone dot com for details on logging into the already running vnc service for a full LXDE session.
8) happy hacking.

D2G
any idea if this could free up the bootloader for the D2G allowing us to modify radio?

No, this will not circumvent the bootloader to load custom kernels. But who cares. many of the things we want, added features etc., can be loaded up in the form of kernel modules. I am not proficient enough to be able to compile my own modules yet but i'm working on a few things.

Radio
Can a kernal module be used to change the radio?

Good share, thank you very much.

ARGH!
I have probably spent 8 to 10 hours trying to get Ubuntu to boot. It seems that I cannot mount the path it wants to mount.
I can as it would seem to do this in shell it self, but still have some errors.
Do you think if I SBF my Droid X then root it - then follow the directions this would work. I am at an end now...and frustrated

Installing BackTrack5 onto the Motorola Atrix 4G

As I am not allowed to post this where it should be, this seems to be the next best place.
Hardware Needed:
* The Motorola Atrix 4G (without this you wont be going very far)
* Atleast a 4 Gb SD card
* a way of transfering data from your computer onto the SD card (The supplied USB cable or an SD adaptor)
Apps Needed:
* SuperUser (If your on this site, you most likely already have this)
* Just about any Terminal Emulator will work (I used Better Terminal Emulator Pro)
* Any VNC Viewing Client (I used androidVNC)
* A Busybox installer (I used Stericson's BusyBox installer)
Software used:
* I used the BackTrack5 version posted by msullivan, found **HERE**:
I used a slightly edited version of the bt file from the bundle
just copy and paste over the original bt file:
Code:
perm=$(id|cut -b 5)
if [ "$perm" != "0" ];then echo "This script requires root! Type: su"; exit; fi
busybox mount -o remount,rw /dev/block/mmcblk0p5 /system
export kit=/sdcard-ext/BT5
export bin=/system/bin
export mnt=/data/local/bt5
mkdir $mnt
export PATH=$bin:/usr/bin:/usr/local/bin:/usr/sbin:/bin:/usr/local/sbin:/usr/games:$PATH
export TERM=linux
export HOME=/root
if [ -b /dev/loop7 ]; then
echo "Loop device exists"
else
busybox mknod /dev/loop7 b 7 0
fi
#mount -o loop,noatime -t ext2 $kit/bt5.img $mnt
losetup /dev/block/loop7 $kit/bt5.img
mount -t ext2 /dev/block/loop7 $mnt
mount -t devpts devpts $mnt/dev/pts
mount -t proc proc $mnt/proc
mount -t sysfs sysfs $mnt/sys
busybox sysctl -w net.ipv4.ip_forward=1
echo "nameserver 8.8.8.8" > $mnt/etc/resolv.conf
echo "nameserver 8.8.4.4" >> $mnt/etc/resolv.conf
echo "127.0.0.1 localhost bt5" > $mnt/etc/hosts
echo "Ubuntu is configured with SSH and VNC servers that can be accessed from the IP:"
ifconfig eth0
echo " "
busybox chroot $mnt /bin/bash
echo "Shutting down BackTrack ARM"
umount $mnt/dev/pts
umount $mnt/proc
umount $mnt/sys
umount $mnt
losetup -d /dev/loop7
Installation Steps:
1. Make sure you have enough space to work with (atleast 4Gb).
2. Edit the bt file with the above coding.
3. Copy over the BT5 folder onto your SD card however you see fit, I just used a SD to USB adaptor that I got with my SD card.
4. Disconnect the USB cable if you have it connected.
5. open your Terminal emulator and type:
Code:
su <ENTER>
6. Type:
Code:
cd /sdcard-ext/BT5 <ENTER>
7. Type:
Code:
sh bt <ENTER>
8. The bt file should run, and leave you with a red command prompt.
Hit the home button.
9. Open your VNC Viewer and enter the login information.
Code:
Nickname: BackTrack5
Password: root
Address: 127.0.0.1
Port: 5901
The screen size still needs adjusting however as I believe it is set at 800×480 currently.

Sick. Just sick.
Cant wait to crack some Wifi with this. Anyone test this out and get a successful crack?

I haven't looked too far into it, however I do believe that this is almost useless as a "cracking" distro on ARM hardware. AFAIK many things don't/can't work. for instance injecting is a no go (real turn off for me, but that is what a netbook is for).

Until we get better drivers for the wifi, we don't have injection, or monitor mode. I've also found editing scripts can be a ***** because the on screen keyboard is either in the way, or the enter doesn't work as enter if using nano, running vi really hoses things up. My external bluetooth keyboard helps with this, but a bluetooth mouse while it works, is waaaaaaaaaaaaaaay (no really) too sensitive on the Atrix. Hooked up to an external monitor in webtop mode it works much better, but I've not tried running backtrack from there.

Yeah I did not even consider the ARM architecture. Very good point.
Do they make a Rosetta type app for Linux? Anyone know? That could at least help use get past the Architectural limits.
*edit*
Still not thinking straight, that app is for PPC users.

In the beginning where the script says "sdcard-ext/bt5" could I edit that to say "sdcard/bt5" in order to boot it from my internal phone memory?

Is your bt folder on your "internal" or external sd card? If it's the sdcard-ext, you'll need to edit the bt script to point to the correct location.

Hmm, tried a lot of things, ended up going to the OP of the original Backtrack on Android thread and use his original file instead, working now.

once you start up backtrack, you need to edit /usr/bin/startvnc . Change that last line to
Code:
vncserver -geometry 940x520

Thanks and yes I did see that somewhere, I just had no clue what file to edit. So is it possible to install things like Flash on Firefox on here or is the no package installer for this? Gosh, sorry I'm asking so much...thanks for the help so far

Firefox is already installed. Not sure if flash is there since it's so insecure.

Laptop dock
After installing BT5 to Atrix 4G, can the laptop dock be used to run BT5?

I just wanted to throw a thanks out there to Exthero (since you only have 2!) for the start up script. Couldn't get it working until i used yours.
I'm having a blast with this

easiest way is on wifi:
see what your ip is
Code:
$ ifconfig
example:
eth0: 192.168.1.3
use a vnc server on your computer connect to ip address in ifconfig (port 5901 default for this chroot)

anyone know if or where the atrix wireless drivers are for this?

Is it that vegacomb doesnt support loop devices:? Or am i missing something else? Ive checked and i have busybox installed and working correctly, but that doesnt seem to have changed anything?
Thoughts?

The vega does support loop devices, infact I have that setup running on my vega on vegacomb right now!
In order to get it working download the new scripts from the ubuntu on xoom section of the androlinux site, that worked for me fine!
Bear in mind, the version of ubuntu supplied in the image file is something like 9.10 which is very old, and the image is only 2gb which doesn't leave enough space for updating. Consider following their guide for building your own image.
Anyway, best of luck, I had to get over a few problems when installing it myself, but that may have been related to my setup, so if you have any problems I will keep an eye on this thread!
Happy Ubuntuing

Thanks for the reply, I will try the xoom scripts and see how I get on. I saw the section about building my own but wanted to try and easy 9.10 install first before building my own xubuntu 11.10. Il let you knw how I get on

Could you post your bootubuntu script up please?
I have tried lots of different loop device numbers but am getting no where!

I haven't altered my bootubuntu script at all from the default xoom one, I will post it at the bottom!
There are a few things worth checking for that may help your problems, check that the ubuntu folder on your sd card with the .img file in uses a lower case U, that caught me out the first time as my vega keyboard auto-capitalises.
Also did your ubuntu.sh script run without errors? It worked fine on mine with the old ubuntu.sh and the new bootubuntu script but you may want to try running the xoom shell script.
Hope this helps!

Right i must be missing something, i cant find the xoom section on the website so have tried your bootubuntu script in my folder but it still fails.
Can you post me a link to the xoom section of the site please so i can start over in case i missed something earlier in the process?
Thanks

right im missing something, even tried this setup here;
http://trsohmers.com/2011/03/06/how-to-run-ubuntu-on-the-motorola-xoom/
and still no luck. I have a rooted device but its almost as if the scripts are not running as root, i get permission denied messages when chmod 4777 and that shouldnt happen as root.
Im running 1.17 of busybox, not that it should matter. I am getting sick of this not working, no idea why, thinking i might have to bin vegacomb to at least work out where root might work (ie a simpler rom).

I can't remember the exact process, but I do remember getting this. I think I was missing the root login. Are you running these command as root? I think you have to use
su

. I haven't done this for quite some time so can't be 100% certain.

Heya, sorry it's been a while since I've been on the forums, it seems like something has more than likely gone wrong when you ran the ubuntu.sh shell script, can you post the output?

I search on the forum but I can't find what is the real problem :
http://forum.xda-developers.com/showthread.php?t=2116059
--> cd /storage/emulated/legacy/bt5/ don't change anything.
I readed that ext2 and chroot not working could come from the 4.3 but I'm not sure about this information.
I readed that most of custom ROM handle this.
/bin/bash doesn't exist, but /system/bin/sh does exists but :
busybox chroot $mnt /system/bin/sh don't changes anything.
I'd be glad if you can help me understanding my problem
Best,
