Having difficulty in finding system mount point

As an experimentation, I'm trying to take a full ROM backup of my Karbonn A35 (a little known MTK based phone) using this method. However, I'm unable to find the "by-name" folder inside /dev/block/platform. There is only one folder there called mtk-msdc.0. This is the output when I run cat /proc/partitions from the adb shell:

Code:

---

major minor  #blocks  name

  7        0      5920 loop0
 179        0    3845120 mmcblk0
 179        1          1 mmcblk0p1
 179        2      10240 mmcblk0p2
 179        3      10240 mmcblk0p3
 179        4    665600 mmcblk0p4
 179        5    385024 mmcblk0p5
 179        6    1355776 mmcblk0p6
 179        7    1382144 mmcblk0p7
 179      64      2048 mmcblk0boot1
 179      32      2048 mmcblk0boot0

And here is the output of cat /proc/mounts

Code:

Is there any easy way to backup the ROM using dd command from inside the shell?

The reason I want to backup the ROM is that later on I want to root and install CWM, CyanogenMod, etc. The said phone (Karbonn A35) is I think a rebranded version of HTC FairPhone First Edition because that's what it says in the lsusb.
