[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.

If you're installing a new rom, ALWAYS do da factory reset, wipe dalvik cache and cache partition!
On the other hand, if you only want to install an "update" (new version) of the SAME ROM you already installed (MIUI for example), you don't need to do factory reset, wipe cache and dalvik cache is enough, copy and flash the updated rom and enjoy in the new version with all your data/apps/messages etc. there!

can u tell me what is stored in Dalvik cache?

if you're on stock roms, then going to cm/miui, do this:
go Recovery
-wipe dalvik cache
-wipe cache
-wipe data
-install the rom
-then it will reboot automatically(or after installation, reboot) then it will bootloop
-remove battery and put it back in, then do 3 button combo (recovery mode)
then install the rom again,
-optionally install kernels, etc
-reboot.
or if you're coming from a same rom, but new version, you don't have to wipe, just install the new version of rom.

I would recommend to never format boot, if not done correctly it may brick your phone.

Hi, I'm using nitrogen OS on my Redmi note 3. It got updated to 8.1.0(Oreo) through flashing from 8.0.0(Oreo). While doing so I didn't clear the necessary cache like dalvik, system in TWRP. Is it necessary to clear the cache in TWRP while upgrading in the android version?(Though I'm using same AOSP based nitrogen os for 8.0.0 & 8.1.0)

A noob question..please help

I searched alooot..but didn't find an answer!

davlik cache is just a temporary cache for all apps, this can be wiped at all times, it will take about 1.5 min to boot after dalvik is cleared.

From what I can remember reading, when a phone boots up it makes some kind of cache of the installed applications.. it allows the phone to boot up in less time after the initial boot (in the initial boot, its making the cache that's why it takes a long time)..
When you wipe dalvik cache, this cache is deleted.. when you wipe the dalvik cache and boot you'll notice that it makes the cache again..

[Q] Which wipe cache should be applied?
