Getting past N7000 LM5 bootloop without wiping

My Galaxy Note N7000 was on the Jelly Bean 4.1.2 LM5 (HK) firmware with "PhilZ-cwm6-ZSLM5-OZS-4.35-signed.zip" installed.
Phone internal memory was repartitioned to 10.9GB for /system and 2 GB for /data since I store most of my files on the microSD card anyway.

The phone was working nicely although I did experience a boot loop problem when I first flashed it because I changed the phone ID with Titanium Backup, so I did a wipe to get out of the boot loop.
But today in my haste to pull the SIM card out of the phone I forgot to completely shutdown my phone before pulling the battery out, and as expected the boot loop returned. :eek:

Searched around xda and it seems that everyone's solution is to wipe the phone to factory default.
The problem was that I haven't backed up my phone for quite a while and I wasn't willing to wipe the phone again and lose all of my data if I can avoid it. :crying:

So after fiddling with the phone, at recovery I noticed that it wasn't able to mount the /data partition, so I fired up adb shell and tried to mount it manually by using "mount /dev/block/mmcblk0p10 /data" but it spouted out an IO error.
Apparently, my phone was stuck in the bootloop because it wasn't able to mount the /data partition because of a file system error which happened because of the unclean shutdown/battery pull.

Figuring that my data is toast anyway if I wiped the phone to get past the bootloop, I experimented with these commands :

Code:

adb shell
umount /data
e2fsck -y /dev/block/mmcblk0p10

e2fsck reported that the journal was corrupted and there was a gazillion of 'multiply-claimed block' errors on the partition, but finally after an hour it finished but with some note that there's is still some error in the lost+found null node something.

I tried to mount the /data partition with Touch Recovery again and it worked, so I restarted and it gets past the boot screen and all my data are still intact.

I am now flashing the new UBLSF and PhilZ new kernel with bootloop fix, I hope that gets rid of the bootloop problem for good.

This seems similar to the problem and solution posted here : http://forum.xda-developers.com/show....php?t=2040107

Hope my experience is useful to others who experience similar problem :)
