[Q] Galaxy Nexus Complete Wipe

Hi everyone!
My Galaxy Nexus has become slow over the last year, I think due to several factors and trash that's been accumulating onto its memory.
I would therefore like to bring it TOTALLY back to where it was when I switched it on for the first time, consequently deleting all data on it.
I have to mention that the phone originally had ICS 4.0.4 and was updated to JB 4.2.2.
I have tried to read a bit about the topic and found out there are many options; but as those solutions also involved the flash of a new ROM, thing of which I'm not intrested, I preferred asking here for further explanations or solutions on what is best to do.
I was wondering how effective the "Factory data reset" that the phone offers under the "Backup & reset" menu of "Settings" is. In particular: does it delete all the data (Cache, personal, as well as apps) or does it leave something behind?
Also, I've read things about CWM, which seems to be the most apt tool for wiping. (I haven't installed it, and do not plan onto; I've only run it temporarily).
If someone could explain me what the following (and particularly the last 3 [such as Dalvik?]) do exactly, I would be very grateful.
Wipe Data/factory reset
Wipe Cache
Wipe Dalvik-Cache
Wipe Battery Stats
Format /system
Also, when I format, will I get the version of Android I had originally (ICS) or the lastest I updated to (JB)? In the latter case... Did the phone store (hence occupying memory) all the versions that were downloaded in between?
Should you have better ideas on how to achive what I need, please let me know.
Thank you!

Anybody willing to help?!

what carrier do u have for your galaxy nexus?

OP,
1) factory reset in the menu in android will wipe everything off the phone, but will not return the phone to the original rom of when you got it.
2)
if you have stock recovery
Wipe Data/factory reset - wipes all data/apps from the phone (including stuff on /sdcard/ )
if you have a custom recovery
Wipe Data/factory reset - wipes apps and app data off phone, leaves /sdcard alone
Wipe Cache - wipes cache
Wipe Dalvik-Cache - wipes davlik cache
Wipe Battery Stats - deletes the battery stats file
Format /system - formats the /system directory ( you will not have a OS after this )
3) the phone will not go back to a previous version of android unless you flash it. end of story.

i decided to go back to 4.1.2 after using 4.2.2 after a few months, and many disappointments later. i ended up downloading factory images for 4.1.2 and the old radios. and then used my older verstion of the Galaxy Nexus ToolKit to flash everything back. it was painless and fast. But I have stayed on AOKP, so i'm unsure how else you will be able to go back fully "stock."

Get a stock rom ,flash .

I do have a stock recovery, but I could temporarily run CWM through mskip's tool: there should be no problem I believe.
Also, if I run "Format /system", and therefore have no OS, how am I supposed to act later? Get the stock ROM from Google and flash it through mskip's tool (in this case, could I do it through the Stock Recovery or I imperatively need CSW?)? Or there is another partition with a backup that I could use?
Further, do you think that formatting the /system folder is pivotal for a complete clean or it just adds the hassle of reflashing?
Just for curiosity:
How will deleting the battery stats affect my phone/battery life, if it will?
What exactly is Dalvik-chache?
Thank you all!

It wipes your stats from your previous ROM ,so when you flash another ROM you get a completely different stats ,so you might get good battery or not depends on ROM/kernel

Wiping battery stats will accomplish nothing useful.

1) if you wipe /system, you need to flash the system.img again.
2) you dont need cwm or a toolkit to flash the system.img from google
3) whenever system.img is flashed, it wipes what was there anyways.
4) deleting battery stats does nothing other than remove the log file (which is the battery stats file)
5) use google for dalvik. its all over the place there
6) STOP USING A TOOLKIT. - http://forum.xda-developers.com/showthread.php?t=1626895

Camera only works w/o flash after rooting (several roms) only stock rom allows works

Hi Guys,
I was wondering if anyone could help me with a strange issue I have.
When I flash to stock root ROM my phone works fine, including my camera, however, when I flash to ANY custom ROM my camera only works when my flash is off. If I turn the flash on the camera attempts to take a picture and then freezes and I have to do a battery pull to get it back on.
I will through a curveball here and say that I have had extremely limited success (but success nonetheless) when I use my original OEM battery.
The flash itself works fine as I can use apps like flashlight no problem.
Oh and app's from the Play store work fine as well w/ flash on.
Anybody experience this before? I have searched and found nothing,
Thanks everyone.

How are you wiping before flashing? I recommend wipe data, cache, dalvik, format /system.
And by "any" ROMs do you mean 4.2 ROMs or both 4.1 and 4.2?

Well the stock ROM was 4.1.1.
The thing is I've had this problem for a long time now so it would be on both 4.1 and 4.2.
New development though, I just re- flashed to PKD ROM and the flash works intermittently. It seems when I take a picture if something closeup with flash it works but when the subject is far away the camera app just goes black.

So, about your wipe procedures...

Sorry,
So when I flash a ROM I wipe data/factory clear dalvik and clear cache.
I've done that from stock to custom.

The next time you flash, have everything backed up/saved to your sd card or pay and follow the wipe procedures I recommended above. It wipes the OS completely off, leaving you a completely blank slate for the new rom. Have your desired rom and gapps on your micro sd card

You forgot to format /system manually in mount/boot, that causes a lot of errors (it caused a bootloop issue when going from stock to Slim for me)

factory reset sprint galaxy s3 and my files are still on phone

hello everyone. i'm having a problem my phone is running extra slow. i'm rooted on stock, dealing with the official crap 4.3 fw. i tried to factory reset my phone. i wiped the data,cache, dalvik and fixed permissions. after the factory reset super user, internal files and teamwin recovery is still on my phone. once i start installing any apps the phones starts to run like the first gen android. i need help. i would like a complete full wipe that will revery everything completely back to stock.
i've already searched before making this post. i didn't see anything any results that had problems of these files staying on phone.

Odin back to stock. You will need the 4.3 tar.
Or go here
http://forum.xda-developers.com/showthread.php?p=47812894
Make sure you format data and system. Factory reset only wipes data, txt, contacts, apps but not system apps like superuser.

Help restoring my DEV note 4 please!!

Hey I have a problem here.I have a dev edition Note 4. I have been running EMSpoilt's first ROM ([Rom][N910VOYU1ANI1][4.4.4] Stock Root Deodex/Knox-Free Updated 11/24/2014) for about 2 weeks now. It was running great smooth as butter until now. I tried flashing his new [Rom][N910VVRU1ANJ5][4.4.4] Stock Root Odex/Knox-Free) but my phone wouldn't boot up, it wouldn't get past the first Samsung screen just keeps restarting. I made sure to follow step by step instructions. Wiped everything but my SD card. Tried it 2 more times and nothing. Tried to wipe cache and all that. Nothing helped. So I decided to restore back to my backed up ROM. Once restored it started to act weird. My finger print scanner doesn't work and I can't download anything another than apps from app store...the phone is very glitchy and almost unusable.. almost like it has a virus. It did get pretty hot when I was flashing the ROM I hope I didn't fry anything. I tried and tried to reset things but no luck. I don't have a backup of stock Dev ROM unfortunately...is there a way to reset back to stock(out of the box state)? I still have root and TWRP recovery works fine.
Anyone help please?

If you want to get the NJ5 ROM up and running without issues I would suggest flashing the NJ5 stock restore tar file in Odin, then flash TWRP recovery in Odin. Once that is done boot into TWRP and flash SU, then flash the ROM. I was having the same issue yesterday and this fixed things for me.

+1 on what airmaxx23 has recommended. Caution: Make damn sure you ODIN the stock restore file intended for the DE, not the retail. If you just want to get back to a fully functional DE without the ROM then ODIN the stock restore file, ODIN TWRP and flash SUPERSU in recovery. You don't have to flash the ROM.

I am having problems with mine, too
After getting into trouble yesterday with a phone that stuck in Verizon logo screen, I was able to restore from backup.
Then I started noticing weird things that I believe were working a day ago.
I cannot download any email attachments, cannot create folders on sdcard, cannot install xposed or even install Fora offline dictionary files I downloaded from PlayStore. I never flashed custom ROMs on my DE, just flashed TWRP and then rooted it. I am still running original SW N910VOYU1ANI1. Screenshots and photos are saved just fine (burst shots on sdcard and regular photos on extsdcard).
Any Ideas? I've tried to restore from pre-root backup, then restored my image that has root and some applications but cannot move from there.

Here is what I would do if I were you:
1. Go into TWRP Recovery and do a complete wipe (system, data, cache, delvik). Do not select recovery.
2. While in TWRP do a factory reset
3. In TWRP, RESTORE the backup you mentioned.
4. While in TWRP clear cache and delvik again
5. Power off the phone and remove the battery
6. Replace the battery and boot
7. If the phone boots normally then power off the phone, boot into recovery and flash SuperSU (Do not try to restore any "image", just flash SuperSU.zip)
8. Reboot the phone

Go to "Wipe" then "Format Data" then type "yes" and hit "go". This will completely remove all data. Under "Advanced Wipe" check "dalvik", "system", "data", and "cache" and wipe those as well.
If that doesn't work you're going to have to start fresh.

When you're in TWRP and select Wipe, there will appear a "swipe bar" that when swiped will perform a Factory Reset. It is the first screen you see when you select Wipe on the home screen. Do the Factory Reset and then clear cache, delvik, system and data. You can do the Factory Reset before clearing cache etc or after clearing cache etc. It really doesn't make a difference in what order you do the Factory Reset, just do it.
If this process doesn't get you back to normal then another option is to flash the stock restore file for NJ5 availble in the Android Development Section. But, lets do the process I've outlined first.

I did everything up to the #7, then powered the phone. I am getting all bunch of errors like "com.sec.phone has stopped" and other I don't remember. It shouldn't be this way, right?
Then I powered the phone off and on again, this time I got the setup wizard without error messages and flashed SU and then installed Xposed. So far, so good. Will install couple apps to see how it goes.

Glad you got it working. I'd have to see the error messages to try, I emphasize try, to determine what might be causing them. Often after flashing or using ODIN to install software you'll get an error message until the system has been rebooted. You should probably power off you phone, again, pull the battery, replace the battery and reboot to see if you continue to get error messages. You shouldn't be getting error messages during boot unless you have installed something that has turned a service off or has altered a service that the system is asking for (that's not technically well stated, but I think you get the point). Exposed Framework is great and enables users to customize many things in Android. But, not all the modules work the same on every device, and in fact some modules will not work at all on the Note 4. If you're trying to run a module that does not work as advertised then you should uninstall that module or not select that particular customization. A misbehaving module can cause problems that manifest themselves in funny ways.

After Factory Reset, Phone is Slow as Hell - HELP!!

I'm rooted on my Galaxy S3. Last month I made a backup through TWRP recovery. Yesterday when I restored to the backup, the restore wasnt complete. I tried to restore again and I encountered the same incomplete restore. My customized settings in the apps were gone and some of the apps I had backed up weren't included in the restore. Looks like something got messed up.
I then wiped cache, Dalvik, data and system. I even formatted the phone. I also did a factory reset. This messed up my phone so I installed a new rooted stock rom. So now, the phone is slow as hell and apps arent very responsive. Everything is laggy and slow. And the play store and youtube have slow connection speeds.
What should I do to fix this stupidity??

Did you try restoring a stock ROM via Odin?

I had the same thing happen before. Odin with a stock rom is all that fixed it for me.

Yes I did. But Playstore downloading speed and wifi speed are slow as hell. What do you suggest?

Are you downloading over WiFi or cellular data network? The phone is running the latest rom without root? After flashing, you you immediately go to b recovery and do a full wipe?

Yes I'm downloading over wifi and its slow. The phone is laggy too. Its running JB with root. I tried a full wipe of dalvik, cache and data or system. It doesnt help.

This is really strange because a factory reset usually does the trick.
This may be a redundant question but was the phone flashed with the correct ROM? I see different variations of the T999 on sammobile.com's website.

Hi audit.. Its not a dumb question at all. The rom was the correct one for my phone. Everything was working fine up until a week ago. Its possible that my phone fell and maybe that caused damage maybe.
Not only that but restoring bsckups through TWRP doesnt yield perfect restores. All my restores have not been complete. Customized settings all returned to default and apps were rearramged differently.
Anyeay, just to make sure, how can I do a proper wipe without wiping out my custom settings and apps? Do I just wipe dalvik, cache and system?

You would wipe dalvik and cache only.
Wiping data wipes apps.
Wiping system wipes the rom.

Thanks for a speedy reply. Can you explain why my backuo restores through TWRP dont yield perfect restores? Custom settings return to default and apps are arranged differently.

I am not sure why that happens but I have used twrp on several phones, including the lg g2, nexus 4, note 3, htc one x, and Samsung tab without issue. Maybe you need to do a full wipe before restoring? Does the phone have the latest twrp?

Hi audit. Yes the phone has the latest TWRP. I downloaded it from the play store yesterday.
I got an important question. I backed up my rom a few days through TWRP as I said. Is it possible to open up the backup on my laptop and search for specific pics? I dont want to restore the rom, since as I stated, I have problems doing so. I just need to get those pics. Is this possible?

I am not sure but it is worth a try.

You download the tar file for d2att, open Odin, put phone into download mode, put the tar file in the pda box, and flash.
