Is a factory reset enough? Or i need to do a full wipe?

Yup, factory reset is enough, but that'll wipe your internal storage too

Anything necessary to do in cwm after flash a modem in cwm?

I want to try different modems. As far as I know, the modem file (zip file) can be flashed in CWM recovery mode.
Do I have to do something else after apply the zip update in CWM? For example, factory reset?

No? If it just says flash in cwm just flash it why would you have to factory reset?

You don't hit update zip. U hit flash zip, either from internal or external sd card . It's considered good practice to wipe the cache when flashing a different modem if I'm not mistaken.

Hi! How do you wipe your phone completley? Not only factory reset, but wiping the phone totally clean.

Using this tool.flash from cwm.remember it will wipe your internal sd-card aswell,so u need an external sd-card to flash new rom or flash with odin.
Happy flashing

Yes ofcause
Just remember that it will wipe your system partition completely..so you will not have a rom to boot into..keep a ROM in hand to flash after you flash this zip..

[Q] Updating a ROM to a newer version

I am trying to update RootBox room, currently in v2.5 to v2.7.
The information in here (http://forum.xda-developers.com/showthread.php?t=1806401) states this:
Coming from another Custom ROM:
Wipe Data/Factory Reset (This does not affect your Internal/External storage)
Format /System (This does not affect your Internal/External storage)
Flash ROM
Flash JB GAPPS
Wipe Cache
Wipe Dalvik Cache
Reboot
However, if coming from the very same room, how should I proceed?
Just Flash the Rom directly?
Should I flash JB afterwards?
And... may I wipe caches?
Thank you!

Ok.
Updating from the same ROM with the same Android version (e.g Jellybean to Jellybean), the follow these steps
- boot to CWM recovery
- wipe cache partition
- wipe dalvik cache
- format /system (under mounts and storage)
- flash ROM
- flash Gapps
- reboot phone
Done.

Maybe I went to fast, but I did just this:
- Flash ROM.
- reboot
It worked, except for Gapps.
Then I rebooted to just install Gapps.
And..., it seems to work fine right now.
Would you recommend me to do the whole process described above?

Extract the kernel (boot.img) from the rom.zip
Flash it via fastboot mode
Goto cwm, & wipe everything
Flash the rom
Reboot

A clean wipe always includes
Format system
Format data
Format cache
Wipe data
Wipe cache
Wipe Dalvik cache
And you may install any Rom provided you use right kernel

Is CWM Full Wipe possible on xperia devices?

Does a full wipe in CWM Recovery not work on the z2 since the kernel and recovery are together? Like in storage if you wipe /system and /data to fully wipe the phone and then install fresh. Would this just kick you out of recovery, making you have to flash the recovery using fastboot again?
Or does the recovery stay in the memory until a reboot? So that you can install a kernel with recovery again before rebooting?
It works fine

Full wipe won't harm recovery.
You could always make flashable recovery and flash after wipe (before restarting, of course) just to be sure...

On most of the sony devices i have played with the recovery is in the Ramdisk ( in the boot.img ) or it can be stored in the FOTA Partition and called upon by the kernel / ramdisk at boot.
a full wipe wont touch either of these.
pvy.
Ok thank you for explaining.
On all of the Android devices if had a full wipe has never wiped recovery.

Early xperias with locked bootloaders and root exploits had recovery in system partition.
