I just got a used A500. How do I do a full master reset so I can make it like I just opened it up new. Thanks guys,
Go to settings>Privacy>factory data reset...
There's also a reset button on your device Or has this button another function?
Yes however I do believe that this does not clear the internal SD storage. I too wonder about the op`s question. How does on completely reset the tablet including the internal sdcard.

If you do this and the previous owner had deleted phone.apk and telephonyprovider.apk from /system/apps, then it'll get stuck at the logo when rebooting. Check to make sure those files are there before doing a factory reset or data wipe.
Also, Check to see what ROM is on it. Is it stock? or is it a custom ROM? If a custom ROM, then to make it new you'd have to install STOCK.
So it comes down to how NEW you want it.
There's a thread that discusses downgrading to 3.01 using nvflash. That's the most sure way of putting back to factory settings, without knowing the exact status of it currently.
The easiest method probably is to just install a custom or stock ROM with a data wipe. But you need to do a little digging to find out if your on the old bootloader or new one and weather or not the tablet is already rooted.
What happens if i delete some apps storend in /system/app and perform a factory reset? Would my Nexus 4 automaticaly download them from the Internet or Playstore? Or is this a way to have a cleaner Stock ROM without unlock the Bootloader, root and flashing a costom ROM? Or are i'm completely wrong? Sorry for Bad English

factory reset only clears all the user data
Doesn't it clear all? Every installed APP , user data .... Almost everything? Like Format all and instal the stock Rom aga in?

installed app would be considered user data. it gets reset to before you activated the device. if you deleted system apps, they should still be missing. you can reflash a stock rom if you want them back.
Factory reset = user data + apps
Format /system = everything (OS + photos, etc)

sorry for upper doublepost
OK. My Idea was to clean up my Phone without unlocking my Bootloader. I hate it when i get some Apps like Google+ or Google Earth or some apps i have never used on my Phone. It is annoying to me every time when i see them in my Appdrawer. So the Idea was to delete the apps i don't use. I thought i could simply delete them and perform a reset. Once they are no longer there the Phone couldn't restore them so i have got a cleaner ROM.
If you delete an app from /system, it will be gone until you re-install it from Play or flash a whole (stock) ROM. Performing a factory reset will only wipe /data and /cache and do nothing else. A factory reset does not install the whole stock ROM again.

youll need to unlock the bootloader and get root access if you want to delete system apps. but you can relock your bootlader and get rid of root after.

Is it possible to unlock my Bootloader, install cwm, instal a custom Rom get rid of cwm and lock the Bootloader again? And whats when i want to send my phone back in case of warrenty? Could i perform a reset to Stock without unlock the bootloader again?
you can reset to stock at any point by flashing the stock img via fastboot. and you can unluck/lock the bootloader whenever you want.
Thanks a lot for every answer. I love this comunity.
I need help in order to format and do a clean re-install of the 4.4 OS (basically similiar to factory reset).
As posted in this thread: http://forum.xda-developers.com/showthread.php?t=2606780, for some reason my storage is taking double the space it should take. Have been using PA 2.99 ROM, and the phone is rooted and boot unlocked.
At the time I don't really care if the phone will remain boot unlocked, as I could do it again after, I just want to format everything clean and re-install the original OS. Just like you would on a PC. Unfortunately I am not sure how exactly to proceed with an android phone to do it. I don't want to brick it by mistake
Cheers

Hi,
The other day I went in and checked some Cyanogenmod updates on my phone. I noticed some updates have been downloaded but not installed. So I went in and manually installed it. Before I proceed, there was a pop up reminding me about something. However, I did not pay attention to it and proceeded to install the update. Long story short - my phone has been stuck on the Team Win Recovery Project v2.6.3.0 with no way of getting back into having phone access.
I have tried looking up various ways of trying to get my phone access back. Some instructions require I plug in the usb - but then when I hit "Start", it tells me to plug in the phone first. Well my phone is plugged in! But since the phone now has no phone access, the pc does not recognize the device has been plugged in! So I am stuck in a catch-22 type of situation.
At this point, I just want to have my phone access back. Is there an easy way to get rid of the Cyanogenmod on the phone?
Any help would be greatly appreciated.
I believe my phone has Jelly Bean 4.2.x on it (rooted with Cyanogenmod)
David.
If you have a Nandroid to revert to, use it. If not, just flash stock. If you don't know how to do that, just search Efrants guide in these forums.

Hi,
Thank you for your response. The closest I could find is a post by mrjraider (How to flash back to a Stock ROM!). However, any instructions I could find seems to require that I have phone access on my Nexus 4 - which put me, again, in a catch-22 - sine I do not have access to my phone, I have no way of doing any of them!
Please advise.
Regards.

Download this:

Also download the latest image from Google.
Before you install the above mentioned software, go to the device manager and delete everything that says Android.
Install the software.
Boot into the bootloader. I'm assuming you can get there if you get into the recovery.
If everything is good, you should be able to use fastboot to flash the stock image. There's a switch - w that will be needed in order to not wipe your sdcard, but I HIGHLY suggest you read up on that elsewhere in the xda site, or Google it.
Good luck!

I downloaded the Google Mako "OCCAM" (for Jelly Bean 4.2). I hit "Start" and the "Cyanogenmod" round logo keeps spinning in an endless loop. What do you think can be wrong?
Thank you.

jd1639, your method seems to be the simplest (I was going to try Wugfresh, however, it requires my phone to be on debugging - phone access to which I do not have!). Please let me know where in TWRP where I can do a factory reset.
Thank you.

I assumed you had the stock recovery. In twrp you could try to wipe userdata, wipe, advanced.

I am confused here you want to get your phone back up and running but you are worried about losing data. I see some pretty good suggestions in here and I hope they have helped but if not I believe better knowledge of how things work prior to flashing would of helped you out.
Now with that said and the links given have you simply tried to do a factory reset in TWRP and then push a rom over to your phone and flash it. Is your phone showing up when plugged into a pc while in recovery. Also flashing images would mean you would have to be in Fastboot mode. Now instructions on all of these methods have been created in xda. Take your time and research because its hard to mess up a Nexus and with a little time and following instructions everything will be ok.
good luck
Use Wugfresh Tookit to revert to full stock, search it on google
Hi playa,
I have to admit I never spent the time to acquire the needed knowledge in rooting an android. My original intention (in rooting the Nexus 4) was just to have the device rooted so that I can remove the bloat ware that came installed on the phone so that the battery will last better.
No, I have not done a factory reset in TWRP and pushed a rom over to my phone as I do not how to do either function. I see 8 blocks on my TWRP screen: "INSTALL", "WIPE", "BACKUP", "RESTORE", "MOUNT", "SETTINGS", "ADVANCED", and "REBOOT".
Which one should I click on for factory reset? And how do I "push a rom"? Where can I find fastboot mode?
No, when I plug my phone into my pc, it does not show up as "device detected".
Thank you.
p.s. I also tried the Wugfresh Toolkit to revert to full stock suggestion from alexcheveau, however, eventually, it asks me to put the device in debugging - which brings me full-cycle back to square one - I needed phone access to set it to debugging, however, I need to do a Wugfresh Toolkit full stock revert in order to have phone access......
Hi
To factory reset, its under wipe button

Hi all,
Just wanted to let all of you know I got the phone service back on my Nexus 4!:good:
I did the factory reset in twrp, then I did the adb sideload. It took quite a while (a couple hours actually).
I would like to thank every one who jumped in to help me out (and a big "Thank You" given to each of you). Again - Thank you all.
Strangely, when I tried to download Candy Crush, after installing, there is no "Open" button, and there is not a Candy Crush icon on the app page. A lot of Google apps do not react when I tried to download.
Thank you.:laugh:
Hey guys,
I've read what I've found about this problem..
In most of the cases this problem occurs after installation of a ROM or some adjustments being made. In my case, I was just browsing when it rebooted itself and got stuck on the X screen (just after the Google screen).
The options that I've found in the forum are:
1) Use Nexus Root Toolkit to reset, unlock, root and possibly relock the tablet.
2) Simply go Bootloading > Recovery mode > Wipe data/factory reset.
Unfortunately, both options involve erasing all the data from the device.
Is there any way to recover the device (turn it on) without loosing the data / how?
Thanks in advance!
Assuming you are already rooted and have a custom recovery and ROM on your internal storage you could try dirty flashing a ROM over it in an attempt to boot.. Other than that idk.

If you didn't do anything to the ROM then the probability is that something has become corrupted. Its a problem we are beginning to see a lot of recently. I guess it may be time to start looking at why this happens. Anyway in terms of your data the best I can suggest is if you can get into fastboot mode power + vol down then you may be able to use the command adb pull sdcard I've never tried it but theoretically you should get a dump of all data on the "sdcard" which on the N7 will be the internal storage. Today's buzz word (phrase) is automated backup.
Programming is a race between engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.
Thanks for the suggestions.
I was using the stock ROM, and the device was locked.
I couldn't save the data. Tried to go Bootloading > Recovery mode > Wipe data/factory reset and it didn't help.
Tried using Nexus Root Toolkit - unlocked the device and used Flash Stock + Unroot => This have helped for now. Soon I will try some interesting ROM rather than the stock one .. I just need to find some time for this
