[Q] CWM 3.0.1.0 and CM7 no Davlik cache wipe

I have CM7 installed (latest nightly). When I reboot to CWM 3.0.1.0 with the SD card I used to originally install CM7, I can wipe davlik cache as per normal use.
When I reboot my nook with N key and power without my CWM SD card inserted I can do everything in CWM that I have tried, except wipe the davlik cache. When I press wipe davlik cache the screen blips for a second then just stays on that menu choice screen that contains wipe davlik cache. I don't get the yes no accept screen and it doesnt appear to wipe the cache.
What am I doing wrong? I assume it is something I do not fundamentally understand about how CM7 works with the different partitions.

There was a trick to this I read before but don't remember where. Try going up in the menus and unmounting the cache filesystem before doing it. It was something like that. I did it once, it worked, and then I promptly forgot it

For anyone else having this problem, an update to 3.0.2.8 through rom manager did the trick.

Converting to ext3

Hello guys, im using cm7 kang build at the moment and i want to try the stock based roms like modaco rom. I understand that i have to convert to ext3 by flashing a zip file called backtoext3, but there are no proper instructions of how to do this, so please correct me if im wrong
1. boot into recovery
2. wipe data
3. wipe cache
4. wipe dalvik cache
5. wipe battery stats
6. flash backtoext3.zip file in clockwork
7. flash rom in clockwork

This should be correct...

No need to wipe

installing RC1 using rom manager over original ROM

When installing CM 10.1 RC1 using rom manager over original ROM.
Do I need to clear some partitions manually or does rom manager do all for me?

For eliminating causes for some problems that may be appear is recommended to do:
- wipe data/factory reset
- wipe cache partition
- wipe dalvick cache
- format system
Doing that, you have a clear fresh device for installing new software.

shouldn't this be done by rom manager automatically?

[Q] How to install correctly?

Hi there!
How is the correctly way to reinstall "CM10.1 native emmc" on my nook? I have have installed 10.2 and want to delete all user data. I´ve tried, but real racing 3 has the right version, after installing.
I have tried following methode:
wipe data/factory reset
wipe cache
wipe dalvik
--unter mount & storage (auch Recovery):
wipe/format cache
wipe/format data
wipe/format system (am wichtigsten!)
wipe/format preload
Preload was not to find in my cwm.
Then I flashed the new file an d wipe cache wipe dalvik cache.
My personal game data was still on the nook.
Can anybody tell me, how to install any version of cm by deleting all data?
Greetings from germany (please forgive me my bad english)

Yes go to mounts and storage and format 'data and datamedia'. That gets rid of your media files too (where that game data is stored).
Sent from my Nook HD+ running CM10.1 on emmc.

When you flash another rom I recommend wiping: Data, Cache, Dalvik Cache and System.
when you flash an update for that rom: wipe Cache and Dalvik Cache, Install update.
Stepts of installing a new rom:
1) Put the rom and gapps on your device
2)Wipe Data, Cache, Dalvik Cache and System
3)Flash the system and then the gapps
4)Reboot
Stepts of installing an update for the rom:
1)Put the updated file on your device
2)Wipe Cache and Dalvik Cache
3)Install updates
4)Reboot
