[Q] about wiping

how much wiping is necessary on the nexus s when flashing roms and kernels? i've had a habit of wiping data/cache/dalvik 3 times each from my epic days when it only had a broken clockwork recovery to work with. is that a recommended procedure?
i also see that when you select wipe data/factory data reset in clockwork, it wipes cache. does this make the wiping cache step unnecessary when installing a new rom?
one last thing. . . every time i wipe dalvik cache the prompt delivers an error. is this normal? is anything actually being wiped?
thanks in advance for your help

Use dalvik-wiper.zip from morfic to wipe the dalvik on your Nexus S.
Steps to flash a rom, kernel:
wipe cache
wipe dalvik using dalvik-wiper.zip
flash rom/kernel
fix permissions
If you're having any issue, boot loops, wipe data.

wow i can't believe i went this whole time without ever actually wiping the dalvik. . . heh
thank you! armed with this info i couldn't resist the itch to do a clean install of my favorite rom/kernel

Flashing a JB ROM

Hey, I'm currently on MIUI ics. I know I have to wipe/factory reset everything. But is it safe to flash on the current CWM? Or do I need to update it or something? Do I just flash the new JB rom like I would switching from MIUI to a stock ics rom? I'm a noob, sorry if this doesn't make sense.

What version of CWM are you running?
You should be fine, but it never hurts to check. You flash a JB rom just like any other. Wipe wipe wipe and flash.

The whole wipe wipe wipe is completely unnecessary. One wipe is sufficient and any additional won't do anything.
It's like saying that unless you wipe exactly 3 times the Android Gods are going to demand a human sacrifice for your phone to boot.

lol i think dvorak meant wipe cache, wipe dalvik cache, wipe data (wipe wipe wipe) but that's my take..
anyway, if you can flash MIUI ICS with whatever CWM version you currently have, you should be able to flash other JB ROM. Nandroid as always.. Goodluck!

This is what I did :
1. Boot into recovery and perform a nandroid backup of my MIUI installation.
2. Wipe.
3. Flash XenonHD 9 JB ROM + marmite 4.2 kernel.
My phone is running really smooth now. Good luck.

Yep, that's it. Of course wiping everything 3 times would be unnecessary.

if you get a cluster f*#@ of problems then clean install. It isn't that hard. Use Titanium Backup and good to go.
In Recovery:
1. wipe data/factory reset (this formats /data, /cache and .android_secure on sd)
2. format /system, /boot
this leaves you with only bootloader, recovery and radio...dalvik-cache resides on /data, so it's gone already.
3. flash rom
4. gapps & custom-kernel (if needed). No need to let the phone boot & settle before flashing them (most custom-kernels have a script that automatically wipes /cache & dalvik during kernel-install)
5. reboot
6. Run TB -- restore missing apps with data --1st option under restore
just updating rom:
1. flash rom-zip
2. wipe /cache and dalvik-cache
3. reboot
Do this before reporting any issues on the thread since the problems are often related to this and not the ROM or kernel.

[Q] How to Update Custom Rom

Hello to all,
I am using Oxygen's ROM 3.0.0 and i want to update to the latest one. Should i flash the update through recovery? If yes, what should i wipe?
Also by flashing the update through recovery my apps etc will be erased?
Thanks in advance!

Just wipe cache and dalvik, and install new zip. Your apps will be there intact.

Bootloop in custom roms

Hi everybody
I have a X1032 model. I'm having a problem flashing custom roms. I'm on stock 4.4.2. I unlocked my bootloader and installed cwm with fastboot " CWM-swipe-6.0.4.7-falcon.img". After that i rooted my phone with some supersu.zip file that i had to flash in cwm. So i have bootloader unlocked and a rooted device. Downloaded C-rom 4.4.3, wiped data/factory reset, wiped chache, and in mounts and storage i wiped /system. After that i flashed C-rom 4.4.3 succesfully but when i reboot the phone its stuck on a bootloop and i can't see why. I've tried it 3 times with no luck and even an older version of it, i tried cm11 4.4.3 but same no luck i tried waiting 20 minutes but it didnt help. Am i doing something wrong? or did i miss a step or something?
These are the roms i tried to flash:

If you can help me please do thanks in regards.

Have you wiped cache? I'm not sure but wiping cache sometimes helps.
You may try Philz touch recovery, too. It can clean the phone to install a new rom, so it may solve your problem if you forgot to wipe a partition.
edit: Sorry, you said you wiped cache, missed it. You can still try another recovery I think. Don't know why but trying another recovery sometimes help. (I saved myself once, but may be just coincidence)

dont wipe the system!

Just stop wiping the system and it will work fine.
i've used cyanogen wiki to install one.

No i didnt what i did is install Philz recovery here
http://forum.xda-developers.com/showthread.php?t=2201860
Go to downlaod Home and search for falcon and look for this one
philz_touch_6.43.8-falcon.zip
download it and put it on your phone and just flash it
then go to wipe data/factory reset you'll get an option to wipe for installing a rom choose that
after its done just flash your rom
it worked at the first time i did it
