I have the xperia z-ized v3.1 rom and I thought to update it from OTA. But when I try to update it closes and shows me a toast message saying invalid md5. Now I have downloaded the v3.4 manually from the OP in the thread and also the samsung keyboard. But do I have to wipe anything before flashing or can I flash directly?

I am not a user of the rom, but a common rule is that if there is a change in base, full wipe is highly recommended.
If it is just an update and not a change in base, then full wipe is still recommended but if you try to dirty flash and not come up with any problem, it's good.
I hope I helped...

I'm sorry but does full wipe mean wipe data/factory reset, cache partition and dalvik cache? And what does dirty flash mean? Sorry if I sound noob but I'm new to all these terms..

It's fine.
Full wipe: /data, /system, /cache, /dalvik-cache (optional: Internal storage)
Dirty flash is flashing an update over your current version without wiping /data

I want to update my Unofficial CM10 +3.x Kernel to the latest update from Hashcode.
UNOFFICIAL CM10 + 3.x Kernel for Kindle Fire [09/16 CHARGING+]
When you do an update like this, do you wipe everything like I did when I first flashed the ROM? I mean, when I installed, I wiped system, factory reset, cache and dalvik cache. Then I flashed the ROM and then I flashed gapps.
So now I just want to update the OS, what do I need to wipe? And will I need to flash gapps again?
CAn't ask this in the development thread 'cause my n00b hat it still too shiney.
Thanks!
A question like this doesn't belong in the development thread because it isn't development related.
If you're going from one ROM to a different one, you need to wipe System and Factory Reset (data and cache).
If the ROM is simply an update of an existing ROM, generally all you need to wipe is data and cache. There are always exceptions to this so it's always a good idea to make a backup in case things turn sour.
After installation of the ROM you have the option to wipe cache and dalvik. It isn't required but not wiping them has been known to cause some bugginess.

Thank you once again, soupmagnet. Yeah this is just an update to my current ROM. So .... I won't need to flash gapps again?
I'm slowly figuring this stuff out. hehehe... When I was 30 I picked this stuff up quick. Turning 60 on Thursday and stuff tends to need a little more pondering lately. hahaha
Anywho.... thanks
Oh, yeah. You need to flash Gapps if you wipe system.

OK, see, now you're messin' with the old man here... hehehe
On one hand I'm hearing if I am only updating my current ROM, I just wipe data and cache.
Then you tell me I have to flash gapps if I wipe System.
But prior you said I only need to wipe system if I'm going from one ROM to a different ROM.
So.... I'm just updating my current ROM. I wipe data and cache, flash the updated ROM, wipe dalvik.... done...
no flash gapps, right?
I need to look at TWRP again to see exactly how it presents the choices. Don't be hatin' on the old guy for bein' dumb now.
OK, booted to TWRP. When I select Wipe my choices are : Cache, Dalvik Cache, Factory Reset, System and then External Storage. So... in your first answer to me when you said to go to a different ROM I should wipe "System and Factory Reset (data and cache)" it appears you are telling me that "System and Factory Reset" is another way of referring to "data and cache". Is that correct?
Gapps go in the /system/app folder so if you wipe the system partition, Gapps will go along with it.

GAaaahhh..... I just wiped System and watched as it processed /system
and then I wiped Factory Reset and watched as it processed /data and /cache
So I guess that answers my confusion.
Total newb question but on the CM10 thread they say:
Instructions:
First time flashing CyanogenMod 10 your device, or coming from another ROM?
Root the device and install ClockworkMod Recovery. Instructions are available here.
Perform a NANDroid backup of your current ROM.
Format the system, data & cache partitions of your device.
Perform a factory reset.
Flash CyanogenMod.
Optional: Install the Google Apps addon package.

.... they don't say how to flash if you are upgrading.
Some in the thread say that they just "dirty flash" it.
What exactly is a "dirty flash"?

dirty flash means you didnt wipe data/cache.
most of the time, you can dirty flash newer versions of the same rom over the older version of the rom you have.
HOWEVER, if you have problems, you need to wipe data/cache and reflash the rom completely

Guess I might as well wipe the cache and dalvik even on a dirty flash?
Thanks
I upgraded from CM10 M1 to M2 with only a wipe of Dalvik cache. Works fine.
I finished installing M2 after wiping both the cache and dalvik cache (figured I would do the cache just in case).
Worked great!
Thanks all

***what Nexus version do you have?*** i've used the below instructions with GSM GNex***
If you're coming from an AOSP CM9 rom, Do the following :
Download Maguro (or your models ROM+Gappsl).
- boot into recovery.
- Preform NANDroid Backup.
- Wipe Dalvik cache.
- Wipe Factory reset.
- Wipe Cache.
- install zip from SDcard>choose zip from SDcard>ROM.zip (your ROM)
- Flash Gapps.zip
- Flash kernel.zip (if you have one)
- go to Advanced> Fix Permissions
- Reboot system now !
- Enjoy.
***I've used this method for a trillion flashes !***
No need to wipe anything when updating nightlies. Like it was said before, wipe data and reflash when you face problems.

When wiping phone for a new ROM flash should I wipe Tombstone and Firmware?

No. Only /system /data (only when install instruction require full wipe) and /cache.
Sometimes when flashing Android 4.3 over 4.1.2, wiping INTERNAL SD may be required - consult the thread as it must be stated there.
sorry for the noob question what is dirty flash
Flashing a rom without wiping /data first. A "filthy" flash would be to flash without wiping even cache and Dalvik
You can dirty flash between minor version updates of the same rom. Whenever you flash a major update (let's say from bestromever JB 4.3 based to bestromever JB 4.4 based) or if you flash a rom from a different developer you need a clean flash, meaning you need to wipe data, cache and Dalvik in your custom recovery.
If in doubt: clean flash

Whats the diffrence between dirty and clean flash?

A clean flash is when you wipe every thing clean. A dirty flash typically is when you don't wipe /data and update to a newer version of the same rom and same android version.
There are plenty of variables that people will do differently:
A normal clean flash will entail wiping/formatting system(often done automatically in the rom installer-script), data, cache, and dalvik/art cache. You can also wipe internal storage(internal sd card/sd card 0), android secure, preload for an ultra-clean flash(not usually needed). Obviously the downside is you will need to install and set up all the apps you want from scratch. Using backup tools like Titanium Backup can help here, but also can lead to problems.....
A dirty flash is normally just rebooting to recovery and flashing the newer nightly and rebooting again with no wipes. A lot of people wipe cache and dalvik/art cache before rebooting. This(dirty flashing) is only advisable if the rom you are flashing is of the same android version and an update that is fairly close to the existing rom. There can potentially be all sorts of issues when you dirty flash due to major changes in the code. The rule of thumb is if you dirty flash and start getting strange issues, then a clean flash will normally solve them.
