Wipe wipe wipe

Just want to make sure what it means of a full wipe. Does it mean wiping data,cache and dalvik ? And does this erase the applications ? Specially if your updating from a older rom ver. To a new one. Sorry for my noobness and thanks for the info in advance.

Full mean everything cache, dalvik cache, data, and even system this will delete all your personal apps. Do this when going to different roms (cm7 to miui, or froyo to gb) when updating the same rom its not really necessary, but you can wipe cache and dalvik cache (wipe these two when flashing kernels) just to be safe, dalvik and cache wiping will not delete your personal apps.

Follow fcisco13's advice. If you wipe data/factory reset from clockworkmod it will wipe data, cache, and dalvik cache all at the same time. So just do that and then format /system and you'll minimize issues.
As said above, if you're only updating to a newer version of the same rom, or to a new kernel, then just wipe cache and dalvik cache.

Hmmm ... during the initial setup of Android are you selecting to let Google backup/restore your apps and settings? If so then your phone will automatically download and restore apps and setting that were backed up to Google's servers from your previous installation.

Tutorial for flashing/installing a kernel

Hi
I just bought my first android phone which is a Google Nexus S, and I guess flashing/installing (I never know which is the correct term to describe this action!) a kernel from XDA can give better performance or some extra features, e.g. BLN
However, I don't seem to be able to find a complete tutorial of how to flash/install a kernel, can anyone help me with this please?
Thanks in advance

First you need root.
Reboot into recovery and wipe Dalvik cache maybe twice.
Then find the kernal in your SD and install
Reboot

wipe dalvik cache once. then proceed to flash kernel

Wiping cache does not delete your data.
Unlocking the bootloader to get a custom recovery will wipe everything.

U dont need to wipe cache. Simply wipe delvik cash then flash your kernel on your sensation.

You don't have a custom recovery? I suppose you could use Flash Image GUI but you're really gonna wanna get a custom recovery. Especially since you want to make a backup before you flash in case something goes awry.
*if you didn't wipe /system and /boot it is NOT A FULL WIPE*

Doesnt matter just wipe dalvik cache and ur good. Through custom recovery

use this guide to install CWM(See Part 3 of the Guide)
once done just wipe dalvik cache in CWM and flash any kernel .zip file

you dont need to wipe dalvik cache, cache, or anything else. as these dont have anything to do with the kernel. you can flash kernels via recovery(in .zip form), or with fastboot/terminal emulator(in boot.img form).

[Q] Stuck on HTC Logo after Flashing Rom (HTC Flyer)

HTC Flyer: Rooted with S-off, with Revolutionary CMW 4.0.1.4
At the first attempt, I flashed the SU.zip and got the tablet working. But then i decided to flash the Leedroid rom.
Within revolutionary, i wipe the data/cache/davche and then flash the new leedroid rom. There are no issues on flashing the rom and it was successful, however when i reboot.... it is stuck on the HTC logo screen. After 20-30 minutes, the tablet just shuts itself off.
Due to this, i decided the wipe again and install a different rom (CoolHoney3D) however same issue. Then i decided to go back to original SU.zip and that is not working now as it has the same issue.
I downloaded the recovery image for the HTC flyer and try to install it with Scottsrom. No LUCK
I believe i am missing a step in the whole process. please let me know what the problem is. I read all the tutorial to do the recovery but i am a noob and couldnt figure it out. sorry for my bad english..
Thanks!

I did 3 types of wipe (System/Cache/Dache Cache) then installed the roms again. It said the Rom installed correctly but still got stuck at the HTC screen. Like i said, i installed the original su.zip again and that doesnt work anymore
Another question, do I have to install su.zip first before installing the leedroid rom?

Skip the "su.zip". So just flash the "CoolHoney3D" rom, wipe the dalvik cache, then reboot. You could format all partition before flashing the rom if you haven't already done so. In other words:
- Format partitions
- Flash the rom
- Wipe the dalvik cache
- Reboot

Dirty vs Clean Flash

A dirty flash is only wiping cache and davlik then flashing your ROM....
a Clean flash is at LEAST factory reset/data wipe + wiping davlik(factory wipe takes care of /cache also)... Maybe doing a format /system also.
SO let the games begin! Which is better?! FIGHT!!

If I switch ROM's I factory reset then wipe cache and dalvik cache. If it's a theme for example I only wipe cache and dalvik cache since the theme is suppose to be made for your ROM right?....don't see the reason to reflash the ROM as well.

Wipe data? What's that for? Is THAT why my phone won't turn on..........
Nightlies: No data wipe (yes to cache/dakvik)
New rom, even if it's the same android build: always, full wipe
Themes: No wipe at all, flash right on, right after flashing rom's. Don't like to wait for two bootups!

Il throw a vote to whichever works.. I usually dirty wipe.. If I have issues then clean it and try again.. With nightlies I tend to be fine dirty a lot, but even still I will do a clean every couple weeks just because..

why do so many folks wipe cache and dalvik after they wipe data? A data wipe/factory reset wipes all three, there is no need to do anything else.
I always wipe data, flash rom, then advance restore data only from a nandroid...dirty flashing in its most elegant form

So we all agree that a dirty flash is just wipe cache/dalvik cache.
Do you wipe prior to re-flashing, or afterwards? Does it matter?

What about flashing a new, updated kernel for a rom you're currently using? What steps should be taken for that? For example, cleanrom 2.1 comes with cleankernel 1.1, but the kernel has been updated to 1.2 and is out as a seperate download. How would you update just the kernel that's made specifically for the rom you use?

I disagree. I believe a dirty flash also wipes system. If you are 100% certain that your ROM build effectively wipes system as part of it's install routine, then you could skip this step, however I always wipe system to be safe. This works for me and I rarely need to wipe data or sd card(s).

When changing Kernels but not the ROM in a separate recovery session than a ROM flash, you don't need to "dirty wipe." Just wipe cache and dalvik. Dalvik wipe is key so that the dalvik virtual machine can be rebuilt by the new kernel.

Thanks for the info guys.

I usually dirty on nightlies until I have issues. Always clean when switching roms.

I find that this method works better than just wiping cache and dalvik, since im advance restoring data over a clean flash. both ways are considered dirty flashing tho.

I wipe dalvik, cache and battery stats. Works like a charm thus far. Wiping data is what blows out the IMEI correct?

Incorrect, flashing anything is what may lead to losing your IMEI. Backup using the appropriate tools in the development section. Btw stop wiping battery stats, it's not necessary.

Factory reset doesn't touch the davlik(Which I speculate(Guess) has to do more with the kernel than anything)

Usually when I flash a new kernel, or a different kernel, I just wipe the davlik cache and I am fine. There was some reboots after the first boot on the AOSP ROMs but afterwards it ran fine.

SlimSnoop is correct. According to one of the developers of a very prominent ROM the IMEI issue was because our phones got confused sometimes(Randomly phone to phone) and tried to reset during a flash. The data it tried to reset was bogus, therefor losing IMEI. He is also correct far as the wiping battery stats. It's only usefull when you have really strange results with battery. Google for the real reason to use them.
Far as backing up your IMEI so you will never run into the problem of losing it.... go into your terminal (almost every ROM has a Terminal emulator)
Type this:
su
then hit enter. Grant permissions
then type:
reboot nvbackup
then hit enter. This will make your phone do some shyt and reboot, but you really shouldn't need to worry about your IMEI after this. Regardless of how many ROMs you flash or what you do or who you date or who you kiss, etc... blah blah....
This really should be the end all for the IMEI...

New rom only when their bases are different , like going from ics to jb, or the dev says to do it (Even then Ill try it without a wipe because im lazy).
Themes I never wipe anything
Nightlies never wipe anything.
Edit: If I do have issues I then go back and wipe delvik and cache . That usually straightens out any issues and allows me to keep my setup.

Yes. You should always wipe.

factory reset,

Than flash your goodies!

It is always best to wipe everything. Especially when you change Roms. If you are on a cm rom and you are just upgrading to the newest version you can just wipe cache & dalvik cache, flash rom, flash gapps, & reboot. I have done it this way for years & haven't had any problems. Most people prefer to wipe everything though.

TY so much

If it's your first rom, or if you're flashing an entirely new rom, do a full wipe. Otherwise, you can get away with just wiping cache and dalvik.

ya iv had it happen to me a few times and to wipe all of them is usually the way to go, you can use titanium backup if you just want to keep your app just if you've upgraded to a new rom like going to jb from ics then do a restore and uncheck all system settings you only want your apps and their data back, if it forces closes just reboot in recovery and wipe the delvik cache and it should fix it up
