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)

[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.

[Q] wipe cache and data?

hello there!
i'm a new little fellah in the rom flashing world, so i'm a little afraid before doing anything, so here's the situation :
i have a galaxy mini, rooted, and cwm is perfectly installed.
i want to install this rom : http://forum.xda-developers.com/showthread.php?t=2085347
In the description it's written to wipe data AND cache after every action.
I just have personally 2 thing to install : the rom and the gapps, that's all (no patch).
So i have to wipe cache and data before flashing the rom of course, and so my question is : do i have to wipe data AND cache after installing the rom? and then install the gapps, and then wipe again?
So should i do :
1) wipe data and cache
2) install from zip the rom
3) wipe data and cache
4) install from zip the gapps
5) wipe data and cache
6) reboot
Is that good? or am i doing a mistake anywhere?
thank you for your help !

normally this works
wipe data ,cache and dalvik cache
format system ( if going from stock to cm7 or vice versa)
install rom
install gapps
wipe data , cache
reboot

you can also wipe battery states but it's only optional, you dont have to but no harm in doing so.

I'm confused, How to format data, system, cache ?

Reading this steps:
BEST WAY TO INSTALL THIS ROM:
- reboot into recovery
- format data, system, cache
- make a data factory reset
- wipe dalvyk cache
- install rom and enjoy ...
How can it be done on GT-I8190 ? Samung S3 Mini

And also, What does "full wipe" exactly mean?

All you can do in CWM. There are,besides other things, this options:
- wipe data/factory reset
- wipe cache partition
- and in advanced->wipe dalvik cache
If you will select this 3 options your mobile will than like from factory

I only have "twrp"
Should I install "CWM" also?

So basically, Format = Wipe?
I thought they are different term.
