push the busybox binary to /data/local/tmp/

adb push busybox /data/local/tmp/.

change permission to execute...

adb shell "chmod 755 /data/local/tmp/busybox"

then enter adb shell and type following commands:

cd /data/local/tmp/
mount -o remount,rw -t yaffs2 `mount | busybox grep /system | busybox awk '{print $1}'` /system

Any risk of bricking?

It shouldn't brick your phone, gonna try it now will report back

doesn't work because of no root access "busybox: permission denied"

great so the system MTD block is at /dev/block/mtdblock0

now try this in adb shell:

mount -o remount,rw -t yaffs2 /dev/block/mtdblock0 /system

--OR--

mount -o remount,rw,relatime -t yaffs2 /dev/block/mtdblock0 /system

and if u dont get any error then post output of:

adb shell "mount"

BTW: how come u have "com.keramidas.TitaniumBackup-1"??? is ur device rooted yet? or were u just trying out apps ?

Nope didn't work:
"mount: Operation not permitted"

We still don't got root, i think till than we can't do anything

I am feeling I will sell my Arc and get an old good Desire or even Desire HD.
SE has unlocked the bootloader but locked the root process in a bizarre way

I don't know what it is but I'm also not liking it
