Garmin-Asus M10 dual booting with android Garmin-Asus A10 ROM

aaaku · Nov 26, 2010

How I extracted the file: I cooked up some custom java code to extract the files. The update file format is not generic. One peice to identify file boundardies and one to extract the file at a certain location.

cht900, Nice research. I tried using the patched haret.exe posted in the forum. Now I see a blank screen. But looks like something starts loading and then freezes. I could not find anything that relates to rootfs.img. There was only one fs image.

Please post if anyone made a headway.

Image extraction tool

Hello,

Here is a small Python script that extracts the files from a raw image:

#!/usr/bin/env python

from struct import *
import re
import sys

if __name__=="__main__":
try:
imageFile = open(sys.argv[1], "r")
except IndexError:
print "Usage:"
print sys.argv[0], "<file>"
print
print "Example:"
print sys.argv[0], "A50_SR2_2_PACKAGE.raw"
sys.exit(1)

OFFSET= 0x1f0
buffer = imageFile.read()
while True:
entry= unpack_from('<24sLL', buffer, OFFSET)
try:
name =re.search(r"(\w+\.\w+)", repr(entry[0])).group(1).strip()
offset= entry[1]
size=entry[2]
print "name=%24s offset=%08d size=%012d" % (name, offset, size)
except AttributeError:
print "Ready!"
break
temp = open(name, "w")
temp.write(buffer[offset

ffset+size])
temp.close()
OFFSET=OFFSET + 0x20

Using it I was able toget access to the content of the ext3 image.

My final goal is however not to portAndroid on a WinMo device but rather to install Garmin navigation app on another device. Any hints?

I can't extract garmin raw file. All extracted files with zero size

grumpyhare · Jan 11, 2011

Have you used the script?

Here is the output on my system:

how to unpack the system_ext3.img??

grumpyhare · Jan 13, 2011

That is a ext3 image.
On a linux, as root, you can launch:

mount -t ext3 -o loop system_ext3.img /mnt

Then go to the /mnt directory and there is the content of your image.

thanks for your answer

I tried it before.
error:
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

dmesg | tail : VFS: Can't find ext3 filesystem on dev loop0.

grumpyhare · Jan 14, 2011

Please try to change in the script the line

temp.write(buffer[offset

ffset+size])

into

temp.write(buffer[offset+512

ffset+size])

Then run the command:

file system_ext3.img

It should detect now correctly the file as being an ext3 image and output its UUID

bearfat · Jan 14, 2011

thanks again.

$./(changed in the scrip).py system_ext3.img
Ready!
$file system_ext3.img
system_ext3.img: data

I still can't mount it.

bearfat · Jan 14, 2011

I misunderstand.

I got it.

file system_ext3.img
ext3 filesystem data and UUID

thank you very much

chemicalbuz · Jan 20, 2011

Asus Garmin M10 Android

aaaku said:
Thanks for all the tips guys. Just managed to extract the following files from the update package:

system_ext3 file system image:
hotfile.com/dl/83156994/76dbe38/system_ext3.img.zip.html

recovery.img and the extracted components:
hotfile.com/dl/83167576/975a3e1/recovery.img.d.zip.html

the recovery.img package contains the extracted contents as well, thanks to split_booting.pl posted on the other forum.

Did not bother extracting the other files in the update package. Not sure if they are important.

Disclaimer: There was no licence when I downloaded the original file. I own an M10 and so I hope I have the right to do whatever I am doing. You are responsible to check your own license rights.

Trying to put these together with haret next.

hey dude

thelocalhobo · Feb 19, 2011

ok i know nothing about programing or anything like that. but if some can make an android ROM for the M10, you can use Gen.y dualboot

hope somebody can do this because really want android

also i found this as well with reg keys that may be helpful

d3nika · Mar 1, 2011

hi guys,

did you manage to boot android using haret? it seems the bug you mentioned earlier is from haret but has been fixed.
this is the link to the new files as posted by the developer:
