HD2 SD/MALDR System.ext2 Auto Builder V1.0 - HD2 Android SD Development

1. purpose just speeding up the system.ext2 file making.I'm lazy....
2. use it in Ubuntu O.S. with root account
3. decompress this auto builder and put it in folder /root or else place
4. put the CWM ROM's zip file in the folder "cwm_rom" and put the kernel modules *.ko files in the folder " kernel"
5.open terminal, cd the folder of this scripts, and execute it.
bash systemext2builder.sh then it will auto build the system.ext2 for SD ROM.
here is a demo how to use http://www.mediafire.com/?3lj5iuiv6ddcppi or http://dl.dbank.com/c0xn7ck608

if you wanna a system.img file too for DAF ROM, add the follwoing line before this line #now unmount system.ext2
Code:
mkyaffs2image $mount_dir $script_dir/system.img
tools.zip is some tools for rom making. put them in the foloer
/usr/local/bin

Wonderful !
Would love to see such an application for Windows OS ....

---

that's very cool! now we can make new sd builds by ourselves
thanks 3dak!

great tool, work great to build miui 1.4.29
Thanks 3dak

It's so bad that I don't use Ubuntu OS!
I am looking for some tool like this for a long time but running in Windows OS!

Use ubuntu.
Just make a live cd or live flash drive. It's worth it

Or use it in a VirtualBox.
It's rather easy

Awesome, I will test this soon!

Problem for build mimu 1.5.20
It's a good application.
I put the miui_HD2_1.5.20_3nhrpwvbo7_2.3.zip into the cwm_rom folder, and copy all *.ko files that extracted from the system.ext2's \lib\modules folder in the miui_HD2_1.5.20_3dak_SD_2.3.4_ACA_r518.7z into the kernel folder, then a system.ext2 file was built with no errors.
I replaced the origin system.ext2 from the miui_HD2_1.5.20_3dak_SD_2.3.4_ACA_r518 by this file, run it from my HD2 SD card, all was fine expect the GPRS. The origin system.ext2 hasn't this bug.
What's the different?

---

Ty 3dak for this. Are there no way to do this in Windows?

the different is my system.ext2 opened PPP mode while official MIUI ROM didn't.

in Ubuntu, how do you extract files from system.ext2?
Any comprehensive step by step?

Just mount it :
mkdir /mnt/mysystemext2
mount -t ext2 -o loop system.ext2 /mnt/mysystemext2
then go to /mnt/mysystemext2 folder to copy or modify

No matter what I do the system.ext2 is always missing in action, nowhere to be found even after I "sudo chmod 777" the folders. I always get the error "system.ext2: No such file or directory"
I have ubuntu installed in a different drive than windows 7
This is what I did: BTW, I always have to sudo since I don't login as root
I put this zipped NAND "Runnymede_0.82.401.1_v1.3_Tmous" to the folder as you instructed,
I extract all the ".ko" files from this ziped ROM and put them in the "kernel" folder as instructed.
I go to terminal and i sudo the bash command. It spits out the system.ext2 file with a lot of other files.
I copy the system.ext2 file to the Desktop.
then mkdir /mnt/mystemext2
then mount -t ext2 -o loop system.ext2 /mnt/mysystemext2
I sudo chmod 777 the folders to be able access them. I even drag the system.ext2 from the Desktop to the /nmt and mnt/systemext2.
Still, all is empty.
What am i doing wrong?
When I try to copy directly system.ext2 to /mnt or /mnt/system.ext2 I get "not enough space error" but I don't see anything in the "lost+found" folder or anywhere else.
And also what program to use in Ubuntu to be able to open and see and edit the contents of system.ext2 in the folder?
PS. What are the instructions to use tools.zip for ROM making?
Thanks!

put system.ext2 in your home folder,
then open terminal,
cd ~ (this will goto your home folder)
ls (check if you can see system.ext2, if no, you put it at wrong place)
mkdir /mnt/mysystemext2
mount -t ext2 -o loop system.ext2 /mnt/mysystemext2
-----------------
or if you want to keep the created system.ext2 is mounted, just open the 3daksystemext2builder.sh,
#now unmount system.ext2
umount $mount_dir
change to
#now unmount system.ext2
#umount $mount_dir
this will keep the system.ext2 is at MOUNT status after the system.ext2 created. check folder /mnt/system and modify or copy
remember to umount it after you finish your work,
umount /mnt/system

thanks again! I'll give it a try. But first, I have to figure out how to get damsel Ubuntu out of that sudden "Read only" blues madness.

Thank you finally found learning to learn!!!
