I want to do a factory reset but i also want to wipe the cache on the device.
Is it recommended to do it for a factory reset or just when you install a custom rom? I have found these instructions for a custom rom but its not clear to me if i can do it for a factory reset:
Install ROM (Sense UI, Cyanogen, etc)
1. Turn phone off -> Hold Volume Down, hold Power button
2. Press Volume Down to highlight Recovery -> press Power to select Recovery
3. Backup/Restore -> Nand backup
4. Wipe -> Wipe data/factory reset
5. Wipe -> Dalvik Cache

So, if i can do it for a factory reset, when should i do it, before the factory reset or after?
Thanks.
If your goal is to just put it back to factory setting, what's the problem with JUST doing both resets anyway?
I don't understand what those wipes do and if they are necessary when doing a FR. I've heard that it might help to wipe the cache in case i have a problem with the phone. That's why i'm asking.
Cache is cache... stored memory. Its like if you watch porn online, you wanna clear cache to ensure no one accidentally bumps in to your profile.

Ok, i understand i can clear the cache. When should it be done? Before or after a FR?
Ok, someone please help. I bet the majority of you have custom roms and you know for sure how to wipe the cache before installing a custom rom.
Please share this knowledge with me. I'm gonna sell the device if i can't get any help. I'm tired of some issues with it.
I tried to enter the fastboot menu (or whatever is called) by pressing the power button + volume down + trackball but it reboots after the checking for an update.zip file because it fails to see any.
What do i do?

Relax.
Do you have a custom recovery? If not, install one (if you want to install custom ROMs).
If you do, when the phone is powered down, press the power button and the volume down button at the same time. You will arrive at your custom recovery screen. Go to wipe and you will see that you can factory reset, wipe cache, dalvik cache, battery settings and rotate settings. I am under the impression that wipe factory data would wipe everything, including cache etc. In general, if you are switching between versions of a custom ROM, you can get away with wiping cache and dalvik cache without having to do a factory reset. If you are going to a completely new ROM then you should back up all apps with titanium backup, nandroid backup (in custom recovery menu) and then wipe (factory reset) and flash your new ROM.
If you do not have a custom recovery and want to install custom ROMs then use this tutorial: http://forum.xda-developers.com/showthread.php?t=611829

I don't have a custom recovery image and i don't want to install anything else.
I want to know if its possible to wipe cache and dalvik cache on stock rom.

I haven't dealt with stock recovery in a long time, but power down, hold power button and volume down at the same time. You will get to the recovery screen, select factory reset (or data wipe or whatever the option is), reboot and you are good to go. Don't worry about cache or dalvik cache.
I tried that. The only options are Fastboot, Recovery, Clear Storage and simlock.
After i reach the screen i get the "checking sd...no image found " message.
Clear storage has only one option: Delete all user data? yes/no.
If i select recovery it reboots.
Does this mean i cannot access wipe dalvik cache?

Delete all user data then. When do you see " no image found"? If you hit recovery and it sreboot then you need to flash the stock recovery again. Forget about wipe dalvik cache, that is not important if you are just trying to factory reset and may not even be available from a stock recovery (can't remember though).
But that looks like Factory Reset to me. I was looking for a way to clear all possible cache. I've read on some other post that a guy cleared the dalvik cache and it solved some problems with his N1.
I guess i'll chose that one.
Thanks.

I must have been confused by the title of your thread and your first sentence starting with " I want to factory reset ..." Honestly, I don't remember but wiping cache alone may not be possible with a stock recovery. Just factory reset, start over and that's your best bet to clear up any issues.
Dear all,
I start using SpeedMod since version K12K.
There is no problem when I update the kernel from K12K to K12L, K12M, K12P, until from K12P to K12Q and so on.
After flashing with Odin and reboot, the phone becomes very slow, both in operation and the touch screen response.
I have tried updating from K12P to K12Q, K12R and K12S, they have the same symptom and slow. When I flash back to K12L or K12P, it becomes normal.
Any advises please?
Thanks in advance.
My phone info:
ROM: Stock 2.2 FROYO.ZSJPE
Maybe you should wipe the dalvik cache and cache. Go to recovery mode - clockworkmod options - wipe dalvik cache. do the same with cache partition.
Then reboot. That first reboot will take longer than usual because the dalvik cache has to be rebuild again. After that everything should be fine.
Thanks for your reply.
I have tried wiping the cache, then the dalvik cache, but it seems remain the same --- slow and lag. I would like to know if there is any sequence, let's say wipe the cache first, then wipe the dalvik cache, then flash the phone? or something else?
After wiping the cache, in general speaking, how long do I have to wait after the reboot?
Thanks in advance.

What i mean is that the first reboot after wiping the dalvik cache takes longer than usual because the dalvik cache has to be rebuild again.
You might check in the task manager if there's any running process cunsuming cpu time, which could lead to laginess. There are many things that could produce lags (widgets,apps etc.) I dont know what's installed on your phone.
Sent from my hand
I see. However, I am thinking if the lag is because of the apps. Since I am using the same apps before and after the kernel update. I did wipe the dalvik cache after flash, but after reboot, the phone response very slow, and whenever I click the home button, it just did not show up.
Any more ideas? Thanks a lot.

What i would do in your case would be:
Backup all important data/apps etc.
Then do a complete wipe and reset to factory defaults.
Then flash the latest firmware: froyo 2.2.1
Then flash speedmod kernel and apply all recommended tweaks.
After that restore app by app and rethink the real use of each app (do you really need/use it?).
Might sound complicated but it might be even easier than loosing more time on hopeless attempts to solve the problem...

Cheers man, this will be my last step. Thank you for your help.

NP Tell us if you succeeded. You might want to try wiping thumbnail database before (forgot to mention that beforehands).

Just done a factory reset (erase data + data cache + dalvik cache)
and flash the new version of kernel. The phone is back to normal now.

PLEASE SIGN THIS PETITION! TO GET US SOME UPDATING LOVE!!!!!
SIGN AND SIGN AND SIGN!!!! THEN SING!,.......: http://www.change.org/petitions/sam...clears some things. Now lets flash some ROMs!
quick question, if you do a factory reset with odin and start from scratch, should you delete everything that is on your internal SD? Would that be a full complete wipe?
That is a FULL wipe but thats not what im talking about. Just the internal phone stuff.
what is formatted when you click to format /boot? for some reason I always thought that formatted the boot loader so I dared not touch that, but now I'm realizing how stupid it would be to even put that option there and how many more phones would have been bricked at this point. anyway when I install a new rom I pretty much wipe everything (including dalvik) except for /boot and /emmc ( I even formated the external recently but moved back images, efs backup, and avatar), then mount /sdcard, insert rom then flash, fix permissions.
formats the boot animation?
or after the VIBRANT logo
it's a ritual for me whenever i install a new rom to go through this installation method. I also notice that i tend to experience far less "bugs" then others.
Odin to Stock JFD
using the update.zip flash CWR
flash ROM (bootloops after updating CWR)
3 button into recovery
mounts and storage menu
format the following
-System
-Cache
-Data
-Data/Data
advanced Menu
Wipe Dalvik Cache
Flash Rom Again
Fix Permissions
Reboot
wait 5 Minutes
Reboot
complete the 1 time google setup
Install your apps Without data
reboot to recovery
Clear Cache/Dalvik fix permissions
Reboot
Play
I use this method from everything from 2.2-miui-ics never a hickup!
Format system wipes the internal sd basically?

Just being curious because some say it isn't cleared in the Factory Reset. Some ROM and kernel devs do suggest clearing Dalvik Cache after doing a Factory Reset because it prevents some apps giving FCs after flashing a new ROM.
Side note: I wipe dalvik about once every two weeks whether I am flashing or not. Helps with cleaning up corpses and getting better RAM usage. Thanks for the info Alan.
extra post :/
Nice find!
..now bend over.
One question Alan.
Can I Odin to stock from ICS passion just like we go from gingerbread or froyo from? Or is there a special way to get back to stock jfd? I want to try out jcc from but I don't know if I could just Odin to stock from passion. Thanks

What you using to reinstall apps and/or app data? Everytime I install a new ROM, I lose all my data connected to an app. For example, I play Drag Racing and you have to create a new login name everytime I install a new ROM. I would like to at least save the data related to that app.

Have you installed any mod after ROM flash ? I've only installed the original ROM and my applis but no mod. That question because few others have wake up problem after screen off, perhaps they have mods.

You can install a new recovery (CWM or TWM). Than you will can do wipes.
Give me thanx please if I helped.
@alexissuper > Please don't be tell people wrong things. You CAN wipe data even with stock recovery. The wipe data function is available in all recovery mode. Flashing new recovery won't solve any problem.
So I think sdcard may cause this problem, format sdcard or partition it. Report back when the problem solved or persisted.

My SD Card has been replaced and not changed anything, I've tried without the card too and nothing has changed, and when I had the CWM it also fought in wipe data
Again sorry for my english D
