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.
I am currently on stock+cfroot LA3. I have attempted to flash several custom ROM via CWM, however I always seem to get a bootloop. I follow directions first, then try the various other directions culled from other posts.
At there prerequisites to flashing a custom ROM such as being on the same base stock add the custom you are trying to flash?
what steps are you following? List them here please.

First is to follow the steps detailed in the ROM post exactly. Some recommend a full wipe, while others don't. Then I boot into CWM, select the zip file from sd card, wipe cache and dalvik, and reboot. Next is to try a full wipe regardless if I get into bootloop.
Looking about I realized that "full wipe" means different things to different people. I'm still curious if there are prerequisites such as the same base before flashing.
Curious about this cos i'm in your boat too. Follow everything but still get bootloops.

ive had the same issue too guys, for me, i started again with KKA, rooted it, and then flash my roms over that with the CF kernel, that works for me, but ive always found installing other roms over fm kernel or abyss will not work on my note, i get bootloops.
When flashing a stock, you should also do a full flash, use the pit file and bootloader if its avail and flash the lot, this way your getting a proper full flash, not just the 3 file method, but be careful and read up first, flashing bootloaders can be risky.

you should change the order you did, like this
if rom need fullwipe.
1. boot into recovery.
2. full wipe.
3. wipe cache and dalvik.
4. select the zip from sdcar.
if rom no need to wipe, ex rom of criskelo you only boot in recovery and select zip file, but you must flash over other custom rom.

In CWM, I don't have an option for "full wipe". I have:
* wipe data / factory reset
* wipe cache partition
and under the Advanced section:
* wipe Dalvik Cache
* wipe Battery Stats
I'm guessing you mean wipe data / factory reset? I HATE to guess!!
Another option that looks like it COULD mean "full wipe" is:
*#*#7780#*#* (on the phone keypad)
There's even:
*2767*3855#
I'll try with the wipe data and see what happens.
Yes, a full wipe or clean wipe is, factory data reset, wipe cache partition and dalvik wipe. So the 3 before flashing a rom and you shouldn't have any issues

Interesting that the first post AFTER the link is someone attempting to define "full wipe"!
I'll add the link to the Tips and Tricks post for future reference.
Hi guys,
I believe this question has been asked multiple times, and i myself tried searching for answers from many various source to clarify my doubts, only to get more confused due to conflicting information.
Let's say now i am on a custom ROM. Before flashing the custom ROM, i made a backup of my stock touchwiz rom using cwm. However i want to revert back to the exact same state before flashing the custom ROM. What are the steps i need to do to restore the backup file?
1) Some sources mentioned just booting into cwm recovery, selecting "backup and restore" option, select "restore" and choosing the desired backup file will allow the phone to restore to the state prior to flashing.
2) Some other sources mentioned needing to wipe cache/wipe delvik cache/format system/format cache etc. first before i can restore the backup file.
So which is it?
Thank you!
Personally, I always choose option 2 if going to another rom. If restoring an earlier backup within the same rom i use option 1.
Don't know excact what the right thing to do is, but it never hurt to wipe cache / dalvik cache / system because you have it all backed up anyway. At least if you backup regulary. I back up regulary and delete the backups i don't want.

Thanks for the tip!
Is wiping cache/delvik cache sufficient in most cases?
Cos i saw a youtube video, where the guy did not wipe cache/delvik cache. instead, he formatted cache, data and system.

Wipe /
If problems format .
jje
Any other things i should look out for or preventive measures i should take for restoring backup from cwm?
i have been reading of cases where restoration through cwm fails and they have to go through the whole process of re-rooting and flashing before being able to restore it
there is no need for wiping, the recovery does it on its own prior to restoring.
got stuck
i erased everything followed 2nd step now its stuck on logo not starting

Well you are in the wrong forum this is SGS3 I9305 .Not your phone ,
.......................................................................
I had my phone stolen the other day, but I got it back (thanks Cerberus). I want to do a complete system wipe (as in deleting current firmware and reinstalling, not just factory reset) as I'm nervous about what they might have done to it, and because it still seems a bit slow, even after a Factory reset, Cache wipe, and dalvik wipe. I have already rooted using method 1.A. from this forum, so I have the "Wipe Data-Cache-System-Preload" option in PhilZ's bootloader (which I'm assuming does what I'm looking for). I would like to use the firmware on the Sammobile website for my country (Chile (ENTEL)), but I have a couple questions I haven't been able to find an answer to.
1. Is what I'm doing safe? Can you use the Sammobile Firmware's after doing a "Wipe Data-Cache-System-Preload"? Will it raise the counter or change the fact that I have a safe kernel currently?
2. Will I lose my current root access and/or PhilZ's bootloader? If so, is this a problem at all? Will I be able to re-root with the same method, or will that mess something up considering that the bootloader had already been modified the first time I rooted?
Sorry for being an overly anxious noob, but I just barely got my phone back, and I don't want to brick it.

Yes you can download the firmware from sammobile or even from here (if it exists here):
http://forum.xda-developers.com/showthread.php?t=1424997
Yes, what you are doing is safe. the method for flashing stock rom is also in the above link. it will not raise the counter, you will lose root and would be back to stock kernel and there is no problem in that.
Yes you can flash philz kernel again once you are done flashing stock rom.
Edit: flash .zip file for philz kernel after flashing rom again to avoid raising counter.
Ok thanks! Is this process of re-installing the firmware going to actually delete the old firmware first? As opposed to just write over it? Will it have the same effect as the "Wipe Data-Cache-System-Preload" option in PhilZ kernel?

it is the process of over writting if you do not clear up the data or system or preload (which you already did and if the rom is non wipe rom). As you have cleaned up data, system, preload and rest it is the process of reinstalling the firmware as there is no ROM to boot to at that point (i.e once you have cleaned up everything).
So in the thread you linked to it gives these instructions:
Installation
1.a Pre installation : (For clean installation, optional)
- Make backup with Titanium Backup or other similiar app.
- First wipe cache and data
And you are saying I should do this instead:
Installation
1.a Pre installation : (For clean installation, optional)
- Make backup with Titanium Backup or other similiar app.
- First "Wipe Data-Cache-System-Preload"
And then continue with the rest of the process?

if you are rooted already and have backed up apps+data (non-system apps) with TBP you can follow any of the method (preferably 2nd) and once you are done flashing, root again using philz kernel and restore apps+data using TBP. Also if you go to philz recovery and then to wipe data/factory reset you will also find option for clean up to install new rom (something like that). Usually this method is often used if you are flashing custom rom but you can still do it even if you are flashing the stock rom (even same) again. Under mount/storage you can also mount USB storage while connected to pc and delete everything from internal sd before flashing too.

It is called "Wipe Data-Cache-System-Preload." This is exactly the information I wanted, thanks so much again!
I've been trying out some of the various roms for the Nexus 6 for the last couple months. My question is about going from one to the other. Everyone recommends a "full wipe' but some describe full wipe as factory reset while others say go into advanced settings in twrp and hit everything. Anyway, i've been wiping everything which also takes out the data in the sd folder and any rom or gapps you were planning on flashing from internal. I've been pushing the zip files to the device from the command prompt once I'm in the bootloader, and then going into recovery to flash. Is this the proper method and what everyone else does? Seems like I'm missing an easier method. Thanks for the Noob help and looking forward to the future of this device..... promising.

I almost never use the advanced wipe feature. The TWRP "factory reset" (the 1st option presented) does the proper pre rom flash wipe without wiping your data, including the download folder.
I would say leaving the internal sdcard is fine...............but you could wipe system in addition to the standard factory reset......
