Can't mount sdcard/data/system in CWM. Solved.
Firstly I want to apologies for creating new thread for a thing on which there already number of threads here. However when I was in this big trouble (at least it was for me) on Saturday evening I searched everything and couldn't find a working solution.
And I would like to request moderator or someone who has better knowledge of what did happen and how it got fixed can make it guide with his thoughts if there is a need to
Let's start with my story. I unlocked bootloader first time and flashed CWM. While restarting I tried to wiped data as told in one of the tutorial and then I restarted. As long as I remember it said you would not be able to boot in CWM again and I said Yes. That's the time when it got stuck to X logo. I flashed CWM again and then tried to restart still nothing happened. I got further and flashed CM 10.1.2.
Then it got stuck to CM logo. I wiped cache, data, dalvik cache before and after; nothing helped. Then I managed to Power off phone and planned to go for sleep. I thought I have ruined my phone
This is how I fixed it:
At the last moment I thought to give it a last try before sleeping. I could not have went to sleep with that I thought
Then I rebooted my Nexus 4 in CWM and went to 'Mount and Storage'. Mounted everything which were in unmount state. Formatted data. Went back a step then wiped data. And restarted. And there it got rebooted in CM 10.1.2
