Arnova 10b rooting thread

Need a tester?

Hello.
I can replace prev tester. My ebook start with OS Adnroid 2.1 and rk28board.
I'm already modded it with anything i can, even ext3 system.img (no luck), but i'm staying on CM7 with Android gyngerbread 2.3.7 with not working wifi. I am trying do wifi work again.

Masheka, I am ready to work more on this. I think I found the issue. Let me know if your still willing to test more.

My ROM work here is based of a stock Arnova ROM. Not CM7, etc.
So what do you want to test?

What are the key moments in systems image porting to ext* filesystem?
I tried it, but every time bricked my device (with and without signing).
Your test stopped at that, I think.

COnverting the cramfs file system to ext3 is the easy part.
I can tell you how if you need to. You also DO NOT sign system.img or do a rkcrc on system.img.

However to make the ext3 file system work you need to take apart boot.img and edit the init.rc file in this area:


# mount mtd partitions
# Mount /system rw first to give the filesystem a chance to save a checkpoint
#mount cramfs mtd@system /system
mount ext3 mtd@system /system wait rw
mount ext3 mtd@userdata /data nosuid nodev noatime nodiratime
mount ext3 mtd@cache /cache nosuid nodev noatime nodiratime

I'll try it now. What is the maximum size of system.img in ext3fs?

[Finless]

There s really no size limit.

However if you look at the parameter file, space is allocated for system.
80000 hex block of 512 bytes
So basically you have space for 268,435,456 bytes.

If you want to go larger than that you have to recalculate the parameter file and it's offsets.

Kind regards

did a rom for the arnova 10b ever get made?

I have an arnova 10b and is wondering if a rom got made for it. I see plenty for the G2 but not for the regular 10b. Thanks for your help

[Finless]

Not really no. I made one that gives SU privs but not a writable /system as the kernel will not mount /system as anything other than CramFS.
