[Q] about wiping - Nexus S Q&A, Help & Troubleshooting

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

Is there a reason to wipe dalvik after doing a data wipe?

So I've been flashing like f'ing crazy lately, and I ALWAYS wipe before flash, even if its going from one beta to another from the same dev.
One thing I ran into though is if I do a data wipe first, I get an error when trying to wipe dalvik afterwards. Is the dalvik cache taken care of when I do a full data wipe?
I'm using RA-Heroc 1.5.2
Im in the same boat as the person above =P
i get the run command through adb error when i try to wipe dalvik
is a bug on RA-Heroc 1.5.2 your dalvik is wipe allready they fix the bug on RA-Heroc 1.6.2

But...After I install a custom rom(it was succesfull) and reboot nothing changes all it gives me my stock rom with everthing erased....So how do I fix that So i can flash a Custom rom
the rom I am trying is NoSense Rom
You probably didn't do a full wipe. You need to format the data, cache, dalvik cache and system. Everything but the SDcard.

[Q] how to wipe?

hi,
i just rooted my mz601 3.2 and i want to install the ics everest.
can someone please let me know how i can wipe the xoom prior the ics flash?
i have cwm recovery installed .
many thanks!!
Boot into recovery you'll find a list of options there. It would also be a good idea to read "Xoom Heaven" posted in the general section first.
Your going to have to Wipe Data and factory Reset, Wipe Cache partition than scroll to advanced and Wipe the Dalvik Cache. After that go to Install zip from SD card.
thanks Guys,
i manage to install the Ics and everything is fine.
what cache / data do i need to wipe when i will flash an updated ics rom?
do i stiil need to wipe all of the above and loose my aps and data again?
thanks!!
I Personally like to do the full wipe thing, just as you did before. Because that's one less thing you don't have to consider when having problems.

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.

Flashing a nightly build

When you have flashed a rom and there are Nightly'ish Builds that you would like to flash, do you still have to wipe data/factorty reset,wipe cache partiton and wipe dalvik cache?

Usually if you're staying within the same area (like CM10 nightly to another) you don't need to wipe data. Just cache and dalvik (also known as a dirty flash). However, this seems increase the chance of having problems so some people always do a full wipe just in case. You definitely need to do a full wipe going from JB to ICS, ICS to JB, etc.
With small changes yes, do devs always tell u when there are big changes, no. Also it seems like when you get around 3-4 dirty flashes things get wonky no matter what. Best most reliable experience is always clean. And remember if u flash dirty dont post bugs until u confirm on a clean flash.

battery cache
Is it a good idea to clear battery cache every once in awhile? What is the main purpose for this option?

Wiping battery stats is useless as stated by google developers. http://www.xda-developers.com/android/google-engineer-debunks-myth-wiping-battery-stats-does-not-improve-battery-life/
Thanks
Thank you very much for the helpful information Tonu42 and Zalithian!!
