[Q] Dalvik cache to be wiped..??

When flashing new custom roms..
We wipe...via recovery select factory reset & wipe cache partition..!!
But do we also wipe dalvik cache before flashing together with the above step..??
What about after flash (i always factory reset/wipe cache partition) avoid force close error issues..
Can we select wipe dalvik cache after flash too (never tried just want to know if any harm will come.. will anything go wrong)
* if i did select all three reset/cache partition/dalvik > will it erase/wipe nandroid backup..??? *

For a wipe rom, I always backup, do a factory reset, flash rom, do another factory reset, boot, then wipe cache and dalvik cache. The dakvik cache is a temporary working area and can be wiped anytime, I clear both caches weekly or if I get any hiccups. Nandroid backups are stored on your sd card so dont get touched, but best to copy them to PC, just in case, keep the last 2 or 3

nandroid backup
So dalvik cache can be wiped any time...many thanks..
When i make nandroid backup via recovery mode, will android system only restore "last backup" or does it allow to choose "other backups"..???
(does it store multiple backups ? OR just one backup very last...
Thanks

You can choose which backup to restore. Standard practice is to wipe dalvik and cache BEFORE flashing.

Couple things on which way to do this when loading custom ROMS. What is the proper order of wiping, restoring and dalving cache?

[Q] Difference between Factory Data Reset vs CWM Wipe

What's the difference between doing a Factory Data Reset and doing a wipe using CWM.
I'recently rooted my Note and now have CWM installed.
I plan on trying a few different ROMs (both newer stock ROMs and eventually custom ROMs) and read in most instances to per a wipe before upgrading.
I was wondering which wipe to use.
Also, if I install Titanium Backup, will it save everything including Contacts, Network settings, icon layouts, webpage favorites, appa and everything else?
Thanks

Cant say surely about the difference between factory rest of data and CWM wipe. But can surely say to flash any rom you need to CWM wipe all the data and cache and dalvik cache from the recovery.
And Titanium Backup is for backing up and restoring all your apps and their associated data and market links. It doesn't backup contact (should auto backup to your google account or use any contact and sms backing app from market like - https://play.google.com/store/apps/details?id=com.idea.backup.smscontacts&feature=search_result) or
layouts . Icon layouts you can save by going to the backup settings of the launcher you are using and favorites you can again backup on your sd card.

CWM recovery wipe cache, is just wiping cache files not data
while CWM recovery wipe data n Hard reset from setting - privacy - erase data(factory reset) is same
CWM function is useful when you unable to boot device normally.

Where is dalvik cache located ? Because if it's in the data or cache partition, then I don't see why I have to wipe dalvik cache after wiping data/cache...

System apps' dalvik-cache in /cache
Data apps' dalvik-cache in /data
Hence just by clearing the cache you clean the /cache space of system apps and not the dalvik cache of data apps.
So you require to do both - clean cache and clean dalvik cache.

Factory Reset will change your Android ID. Some apps with custom DRM may stop working. Factory Reset is also incompatible with some ROMs and causes some apps/files installed by CWM flashable ROMs to disappear.

I think both are same. Both format data and cache partition.
(that is why devs warned not to perform FDR on affected kernels)
With FDR you initialise the command from booted phone.
CWM Wipe is what you do from recovery mode.

[Q] Wipes and formats

One question, maybe noob ...
When we made flash a new rom from recovery, we made the wipes;
- Wipe cache
- Wipe Dalvik
- Wipe data / factory reset
But
I notice that when you make the wipe all data / factory reset, the system partition is not formatted, it influences the functioning of the new rom?
For sure, I always do the formats in "mount and storage".
- Format cache
- Format data
- Format system
Thank you! Hugs! :silly:

I only
- Wipe Dalvik
- Wipe data / factory reset
I thought when I do wipe data, then I delete the cache.
Sometimes I wipe SD for delete cache & thash of deleted apps.

Ok.
And the system partition?
When you wipe data / factory reset, the system partition is not formatted.
As I know the main files are in the system partition.
Ty for support.:laugh:

Extremely noob TWRP question

So I just started using TWRP and its awesome and I wanted to a simple cache partition wipe like you know the wipe cache partition on a stock recovery, so I was wondering if I should just select the Cache option in the Wipe menu or both the Cache and the Dalvik Cache?

i always wipe both, cache and dalvik - never hurts.

Thanks.

How to Wipe Cache Partition m

Sorry if this has been posted or asked already, I tried to look up and couldn't find any.
So where on earth Wipe Cache Partition is on Nokia 7 Plus? I did tried to go into recovery, can wipe data but there is no wipe cache partition. There was an another user who didn't had the option either so I guess 7 Plus don't or is it hiding under something?
Thanks.
