[Q] Rom Manager - Pre Rom Installation? Dalvik?

In Rom manager when you go to install a .zip/rom from the sd card it offers you "Pre Rom Installation" options.
1. Backup Current Rom
2. Wipe Data and Cache?
My question is does this also wipe the dalvik cache? OR do I need to go into Clockwork and manually wipe the dalvik cache prior to a new rom installation.
I'd prefer someone who knows the answer to this question vs. speculation.
thank you so much!

I know this is somewhat speculative but I am 99% sure on this. I believe that it does wipe the dalvik-cache. The dalvik-cache is in the data partition, so if you wipe data you've wiped dalvik-cache. You can always clear the dalvik manually in recovery if you're unsure.
edit: Did a quick search, I am 100% sure of this now.

[Solved]Wipe Dalvik Cache

I tried to manually flash ROMs by booting into recovery. But in order to do that I need to do a full wipe. But I am not sure for this particular "Wipe Dalvik Cache" option. I select it and it says E:Can't mount /dev/block/mmcblk1p2 (Invalid arguments)
But after I press Yes - Wipe Dalvik Cache is says Dalvik Cache wiped. Have I actually wipe that dalvik cache? =/

That's an error normally caused if you wiped data and cache then went onto wipe the Dalvik-Cache manually in the advanced menu.
What you are doing is trying to wipe it twice and it gets confused so throws up this error.
As a general rule you shouldn't need to use this advanced method if you have already wiped data and cache.
Not the best answer but I believe to be accurate.

Just use full wipe 1.3, saves loads of hassle for wiping between ROMs.

Depends on how often you update and change ROMs as has been discussed many times. This question was just asking about dalvik cache.

Oh looks like I am wiping too much. haha. thanks guys!

[Q] Rom updating w/o losing data?

Updating aokp for example, the aokp updater told me about the update but is it the same process as installing for the first time? Will I lose my apps and everything or does it only wipe cache? What step in roms delete everything, format data or factory reset or both?
Cheers.

No wipe needed if updating.I recommend wiping cache and dalvik-cache for good measure tho. And you have to reinstall gapps after the rom as well.
When a wipe is needed you want to select factory reset. Never select wipe/format data as it'll wipe the internal storage too.

Then what about...
If you are already on AOKP and doing an update:
1. Make a nandroid (backup in CWM)
2. Format /system
3. Wipe cache
4. Wipe dalvik
5. Install new ROM zip
6. Install gapps
If you end up with issue or coming from another ROM, do this:
1. Wipe data/factory reset
2. Format /system
3. Wipe cache
4. Wipe dalvik
5. Install new ROM zip
6. Install gapps

Isn't a Format/system wiping the apps? Or does that not affect the apps? By format on my recovery it says formatting the sd card deletes everything (on TWRP).

Weird notification issue that causes lag....

So, been running the nightlies and have noticed something since the latest M1.
I haven't narrowed down exactly WHEN it occurs, but it does occur often, I believe it's mostly when the screen is off though....
I'll receive a notification (gmail mainly, sometimes an sms) and my system goes nuts in that the haptic feedback is full force and gives double responses usually, followed by extreme lag to the point where I can't even answer calls if someone calls me. I am forced to restart, is this a current known issue? is anyone else having this problem?

Did it anyway, that notification issue has stopped (thanks!), BT seems to be working OK....modem didn't change and now cell signal seems to be slightly worse than it was (LTE), but still acceptable. Trying out the newest modem to see if it helps any...

[Q] Please help with installation CM10.1 - Android 4.2.2 - LegacyXperia Project rom

Hello all,
can you help me with installation this ROM?? Because, i don´t know, how precisely install this rom. I have first time flash kernel, which has in zip? Then go the CWM and
- wipe data/factory reset
- wipe cache partition
- mounts and storage - Format Cach/Data/System
- advanced - wipe dalvik cache
and then install rom, gapps?? It´s all?
Thank you very much.
Martin.

Please READ the installation instructions on the first post.
And no point telling anyone you don't know how to do it, Google is right in front of you.
To answer your question:
- flash the kernel
- boot into CWM
- flash the ROM.zip
- wipe data
Mount and format = wipe
You just repeated the wiping process for data and dalvik
In my experience it is not compulsory to wipe cache and dalvik when installing new ROM.

popthosegaskets: Thank you and i´m sorry.
Last Q. As you write, the last point wipe data = wipe data/factory reset, wipe cache partition and mounts and storage - Format Cach/Data/System?? Sorry for my ignorance.
