[Q] What is Clean Install?

Hi all
When all we have problem when installing a new rom, or system becomes unstable, everbody answers as "make a clean install".
But What is Clean install?
I'm entering recovery mode and doing,
wipe data/factory reset
wipe cache
wipe cach partition
With Clockwork Recovery mode.
What should i do more ? Is clockwork mode a problem ?
What m I doing wrong ?
Forgive me for my english

I'm kind of wondering about this myself.

Having a huge problem with my phone not wiping.

Okay, I was on AOKP M4 and I wanted to upgrade to M5.
So I backup everything and make a backup of my ROM. I wipe the phone and caches and flash M5 with the GAPPS, with the latest CWM touch recovery. When my phone reboots I notice I have the same wallpaper as before and when I unlock my phone my pin is still requested and all of my apps and settings stayed exactly the same. I was never asked to sign into my Google account and the start up/set up screen never came up. I checked to see if I even updated and yes I was on M5. Now the ROM isn't very fast or smooth and I get a lot of force closes and things not working properly.
I tried the whole process again with the CWM non-touch recovery, and again my phone did not fully wipe and all my apps and setting remained exactly the same.
I tried it again with the TWRP touch recovery, and again my phone did not fully wipe and everything was the same and my phone remains kind of slow and I'm getting a lot of force closes.
Why is my phone not fully wiping? What can I do to fix this?
I would really appreciate some help!

you need to wipe factory / data.
wiping cache and dalvik doesn't wipe "/system/etc etc etc"
1. Wipe Factory
2. Wipe Data
3. Wipe Dalvik
4. Flash ROM
5. Flash Gapps.
6. Flash Kernel
for full wipe.

Yes, that is what I'm doing. I'm wiping factory/data and I'm still having the same problem

Like with the TWRP recovery, I went to wipe, I hit factory reset, then cache, then dalvik cache and then flashed the ROM and GAPPS and all my apps and settings stayed the same. It was like if I had dirty flashed it. I don't understand what's going on.

1. Wipe Factory

***FORMAT /SYSTEM*** (under mount in CWM I believe)
4. Flash ROM
5. Flash Gapps.
6. Flash Kernel

What does that do exactly? Would I have to worry about my media and sd card being wiped?

Okay thank you, I guess this time in TWRP I'll do factory reset, cache, dalvik cache, and system and see if it works out

Okay, so I did factory reset, cache, dalvik cache, and format system.
I flashed M5 and GAPPS, rebooted and everything was still the same. My phone did not fully wipe.
I don't understand what's going. I'm so frustrated right now

I would do a factory reset, if that doesn`t help flash a stock rom and root your phone again. BTW don`t you have a nandroid backup to revert to

I have a nandroid backup, but that doesn't solve the problem of my phone not wiping.
I guess I'll unroot my phone and lock the bootloader and re-do everything to see. I don't understand why my phone isn't wiping correctly.

sometimes cwm just doesnt work with factory wipe. i've used it a few times now and sometimes it works and sometimes it doesnt. i have no idea why. you can try doing a factory wipe from the phone settings>backup and reset. ive only done that twice but it worked both times. if that still doesnt work just go with a fresh flash of google images using fastboot.

Init.d folders can only be wiped with a factory reset afaik, or manualy off course. By locking and unlocking the phone you perform a factory reset anyway, so i would flash a stock rom and start fresh. No chance on left files or scripts. You can do it with GNex Toolkit, option 8. Put the downloaded and not extracted .tgz file here C:\Galaxy Nexus ToolKit\put_google_factory_image_here and flash.

Thanks guys, I'll try that!

[Q] About Dalvik Cache

planning to install cm9.1 on my phone, i rooted my phone and installed cwm 5.0.2.7 i wipe the Wipe data/factory reset and cache sucessfully but i cant wipe dalvik cache, my phone hangs up when i pressed it and goes back to the cmw homescreen..
i installed cwm 5.0.2.6 and had the same result.. what will i do to wipe dalvik cache? is it necessary to wipe it before installing a custom rom?
or should i just follow this install guide from Maclaw
"Flash Cyanogenmod 9:
Download and copy the latest CM9 ROM to SD Card
Reboot to Recovery Mode
Select Install zip from sd card
Select Choose zip from sd card
Select the new CM9 rom package
Select Yes - Install update
Wait till the Installation is finish
Now select Wipe data/factory reset
Confirm
Now reboot to phone.
Wait and enjoy CM9 on your Galaxy Gio "

You don't have to wipe dalvik, its wiped in wipe data/factory reset.

Well, dalvik cache wipe is unnecessary if you wipe data.

Wipe data/factory reset.
Wipe cache
Wipe dalvik cache
Format system ( only if you have flahed the right stock kernel for the rom, and have the rom on your sdcard ready for flashing )
Fix permissions
Then flash the rom again. Should work fine then. Read and follow the instructions on the Rom page and you should be fine.

Newbie questions

Ok experts.
First of all, thank you for reading this post. This shows me you read the subject line and in your heart, you are willing to help others ( in this case, me ). And for that i thank you.
So...i have flashed roms before on samsung and htc devices. Why is it so hard on LG?
I downloaded a rom and gapps, opened twrp and did wipe cache, dalvik cache, system but not the data because if i do i loose everything including the rom and gapps i downloaded. Then i fashed rom wiped cache and dalvik cach, flashed gapps wipe cache and dalvik cache then fix permission then reboot and it stays stuck on bootloading screen.
Please point out to me what im doing wrong or what am i missing. I have tried flashing this rom 10 times.
Again thanks.

It looks like you're doing it right, but there's a couple things that might be missing.
You should be wiping data also. So in TWRP 2.5.0.0, select the Wipe tab, Factory Reset, then Advanced tab, and select all 4. /system, /data, /cache, /dalvik. This way you have a clean slate. DO NOT HIT THE FORMAT DATA!!! It erases /data/media.
If you're flashing CM for the first time, you need to either use teeny bins, or (I think this still works) flash the CM 10.1 ROM by Shelnutt2. This updates your partitions needed to run CM based ROM's.

Wow. It worked. I failed to notice that reseting the phone was not formating the data...so it worked.
Big thank you.
Issue solved.
