[Q] About installing CM7 Nightly builds

Hey guys just a quick question about installing nightly builds on the nook. When Rom Manager asks whether to wipe data/cache and what not, if I select it, will it wipe the internal memory completely? leaving no user files behind? or will it only wipe the system files?

It will wipe everything and it will be a fresh install.

If you update, just wipe cache

It wipes the /data partition but doesn't wipe /sdcard /sd-ext or /met/emmc.

Just wipe Davlik.

Note: wipe cache and wipe Dalvik cache are 2 different things.
+ wipe cache is a quick way to clean the current running ROM
+ wipe Dalvik is a completely clean.
After wipe Dalvik, next time it boots, it will take a lot longer time due to the device has to re-compile the whole thing before ROM start running and booting.

I think I need to drop a few lines about wipe cache/Dalvik.
As I posted above, I said it wiped clean.
Apparently, I am NOT 100% correct.
I just updated to nb198, wiped cache (formatting /cache) then wipe Dalvik cache.
After done updating ROM, booting up, I expected everything clean, completely fresh.
It's not the case, I went to Market and all old search history were still shown. Not only with Market but other apps too.
So
a. either wipe cache/Dalvik is NOT completely clean wipe or
b. it was completely clean but somehow, those old cache info, which stored somewhere I don't know, get automatically restored back.

Okay, I did a quick read of the FAQ for CWR, and came across these:
Wipe cache partition
Wipes the cache partition of the device to clear all the data accumulated there over use. This is often used before installing a new ROM, app, kernel or any similar mod via recovery.
Wipe Dalvik Cache
Allows you to wipe the cache for the Dalvik virtual machine (the custom-built Java virtual machine for Android).This is required before most ROM installations and at other occasions too, for fixing some problems.
So, I'm taking this guide on board and will wiping Cache AND Davlik. So that's two steps prior to installing a new CM7 nightly build.

You didn't happen to store them in uSD card? Or perhaps app data/cache are separate from system data/cache...
Will look into it further...

CWM wipe internal storage?

Will a cwm data wipe, wipe my internal storage?

If you're referring to wiping cache, dalvik cache, or factory reset, then no. However, there are specific options to format the internal storage, and obviously, those will wipe the internal storage.

[Q] Change rom using TWRP recovery

Hi, I'm on PA 3.99 rom and I'd like to install Purity Rom, but it's required a full wipe. My recovery is TWRP, so for a full wipe I need to wipe cache, dalvink cache, system and factory, right? Internal and External card isn't necessary, right? Because It will erase the Purity zip in my memory and I won't be able to installed. If possible I'd like a clear response, so I'd finally understand what to do exactly with no more worries.

That's correct, cache, dalvik cache, data and system. Your external sd and internal sd should be untouched.

A factory reset in recovery wipes /cache and /data ... the dalvik cache resides on the data partition and is thusly wiped also.
You could wipe /system to be "thorough" ... but the Rom zip.should have a format /system line in the updater script.
I only ever do a factory reset between roms.

Thank you very much, it's what I wanted to hear! (Never understood if wipe factory was even wipe data ahah XD)

Oh ok!! Now I get it! Really appreciate everyone answer! (Sorry for my English, lately I haven't been using it very much!)

What do I wipe in TWRP when installing a custom ROM?

Excuse my ignorance but I've been out of the game for 3 years and not familiar with TWRP as I used to use Clockwork Recovery. What do I need to wipe when preparing to install a custom ROM? Do I just hit factory reset in TWRP or do I advance wipe?

Wipe everything other than the partition you have the custom ROM on, so if your custom ROM is on external SD, wipe and format the whole internal
When upgrading from the same custom ROM to a newer version, you only need to wipe System and Caches

It lets me wipe:
- Davik cache
- Cache
- System
- Internal Storage
- Data
So I should wipe everything but system or?

You need to wipe everything, sometimes internal storage, sometimes not. I wipe everything including internal storage though, as a lot of unneeded files are kept there. Just transfer what you want to keep to your pc or external card.
