[ISSUE/WORKAROUND]Strange Problem while flashing a ROM from CWM Recovery - Galaxy S II Q&A, Help & Troubleshooting

I'm currently getting strange issue while flashing ROM from CWM recovery and in process of finding solution for the same. Meanwhile, I thought it would be better to create a thread so that anyone else who has same issue as me will find it useful or someone who has solution can guide me.
Phone Details
S2 with 32GB Class 4 memory card
Issue Description/Repro Steps
Issue started when I moved from CheckROM v6(GB-Siyah 2.6.1) to I9100DXLP9 (4.0.3).
Steps:
1) Flashed DXLP9 through ODIN(went smoothly), rooted with CF root v5.4 given in http://forum.xda-developers.com/showthread.php?t=1544487 thread.
2) Used Triangle away to reset binary counter
3) Rebooted in recovery, wiped data/cache/dalvik cache, now while wiping dalvik cache I got an error E:unknown volume for path [/sd-ext], but dalvik cache got wiped.
4) Now flashed Foxhound ICS ROM and rebooted.
5) Bootloop
6) Again repeated Steps 1-3
7) Now flashed Hydrogen ICS 4.0.4 and reboored..still bootloop
8) went to download mode, Repeated steps 1-3 again
9) Now, decided to investigate this issue little in detail and noticed that while wiping data partition through CWM was giving this error:
Failed to mount /data/.android_secure
So, this was the culprit, if data partition isn't getting wiped that means CWM is not able to write on it either but ODIN is
10) So, to experiment flashed Hydrogen ICS through CWM -> rebooted phone -> checked that bootloop was still there -> put phone in download mode and Flashed Siyah 3.1.2
11) Voila!!!! phone booted successfully with Hydrogen ICS ROM, also strangely binary counter was not increased
But Step 11 is still a workaround for ROM flashing issue, I still need to flash kernel separately after flashing ROM.
Any suggestions/questions are most welcome
Hoping to resolve this issue soon!!!

Try this:
1 Wipe data, wipe cache, wipe dalvik,
2 Install from sd card in CWM this http://forum.xda-developers.com/showthread.php?t=1363738.
3 Install the rom.

You may have to format /system by going under "mount and storage"

Reflash a CWM and Root Kernel should have been the next step
same problem format cache system and data
.and factory reset

@JJ
Already tried those steps..still result is same.
I'm beginning to think that somehow data partition has become corrupt(same like Siyah rc6 issue) and it can only be flashed via ODIN. Still, mystery is how my binary counter is not getting increased when I Flash kernel via odin
