As title suggests, I'm considering selling this lovely device. Though I may get it again in the future, I'm only selling it so I can get a dam, phone, been phone less for about 2 years now because darn monthly plans are too expensive.
Anyway, my question is. How do I ensure my device is safe to sell? Meaning, I need to make sure I delete everything on this device and ensure nothing of my personal data or cache is left behind. Does factory reset get that job done? Or is there more steps and procedures I should follow?
My Nexus 7 is also rooted and unlocked.

Flash a stock image, where most things will be wiped. I'm not sure about /sdcard though, you may need to do that manually. Once back on a fresh stock image, re-lock the bootloader.
What if the customer wants it rooted and unlocked? Factory wipe and move sd card contents to my computer, will that do?

Factory data reset if they want it unlocked and rooted they can do it them selves

Hello!
I would like to know if there is a method to root the Nexus 7 without unlocking the BL?
Could not find an answer in other threads...

you need to unlock the bootloader to install custom roms etc. I'm sure you could root the device install a su binary and super user and then easily relock the bootloader with a single command fastboot oem lock. What exactly are you afraid of? It's super easy if you have android sdk installed.
I don't wanna void warranty... and I don't want the related factory reset.

Then you won't get root.

You can backup everything using adb backup (okay there are some app you can't backup with that, e.g. Temple run or Subway Surf) and after unlocking restore the backup
Hi everyone I was just wondering if its possible to downgrade my nexus from 4.2.1 to 4.1.2 if I'm not rooted. I'm currently not interested in rooting my device so is there a way to do it without rooting/unlocking?

I can't flash things because I'm unrooted. So I don't think this method will work. Correct me if I'm wrong.

I do not know for sure but I quite doubt it.
I am curious as to why you want to though. Not that there's anything wrong with wanting to downgrade, of course.
Have you tried one the took kits available? Check around in the Nexus 7 original development section. Look for Wuggs.

I looked at his toolkit but it basically says that I have to root in order to even use the toolkit so is there a way to downgrade without having to go through that rooting process? For now, I don't want to root my nexus
Sent from my Nexus 7 using xda app-developers app
Don't try to root it you'll only manage unlocking the boot loader then when you try and root it it will get stuck in fast boot mode I tried about every rooting program but it could be because my Comp is running windows xp lol

It's so easy to just reflash stock and relock the bootloader that you really have nothing to worry about. If you want unrooted stock 4.1.2 just unlock the bootloader, then flash the stock image of 4.1.2, then relock the bootloader after. It's a really simple process.

If i'm not mistaken, as long as you flash back to 4.2.1(which is the os it came with when u got it out of the box), and then re-lock the bootloader, unroot, then your warranty wont be voided mate. hope I helped.

Yeah, I've done this plenty of times with my Nexus 7 and even the Verizon Galaxy Nexus. As long as you're on a stock image with a locked bootloader, they won't give you any trouble or claim you voided your warranty, as there's really no way to tell. I've gotten into the habit of unlocking and rooting my device as soon as I get it, and if I find a problem I just revert back to a stock image, relock the bootloader, then send it back in. I have yet to have a single issue.

You don't need to worry about saving your stock image. The person above you is talking about saving the stock image to return to after flashing a custom ROM.
There is no way to revert back to 4.1.2 without root access. Doing a factory reset, about the only thing you can do without root, will only return you back to stock 4.2.1
My advice just stay on 4.2.1 whatever your issue is with it.
Otherwise use a toolkit. You will need a PC and the 4.1.2 image. Wugfresh has a website. I would start there.

I actually was just referring to the stock images you can get directly from Google or from goo.im. It's easy enough to just use the 4.2.1 stock image from Google to just restore back to how it shipped, and then relock the bootloader.

Completely agree with this... I have, on several occasions, reflashed stock, switching between 4.1.2 and 4.2.1 - (for me, it was more of an exercise in learning about fastboot and adb... and making sure I had TRIED AND TESTED factory images on my laptop as contingencies should anything go wrong when I came to start flashing custom ROMs).
-----
You don't need root to flash a factory image... everything is done with fastboot; with the Nexus 7 in FASTBOOT/BOOTLOADER mode (from complete shutdown, press and hold Volume Down button... whilst holding, press the Power Button).
(Root is meaningless anyway, here in FASTBOOT/BOOTLOADER mode, since /dev/block/mmcblk0p3, the SYSTEM partition, hasn't even been mounted yet - so no SU binary available... whether or not it exists, it's sort of irrelevant).
- here, for example, is the flash-all script from 4.1.2 (nakasi-jzo54k)... (Nexus 7, WiFi model only).
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-3.41.img
fastboot reboot bootloader
sleep 10
fastboot -w update image-nakasi-jzo54k.zip
After running this script (flash-all.bat if in Windows, or flash-all.sh if an Apple user) you can optionally choose to lock the bootloader with... (if you're concerned about warranty issues).
Code:
fastboot oem lock
-----
If it was the case you needed root to run...
Code:
fastboot flash [partition to be flashed] [IMG file to flash]
...you wouldn't be able to flash a CUSTOM RECOVERY like CWM or TWRP... and thus, you wouldn't be able to flash Chainfire's UPDATE-SuperSU-v1.00.zip (http://download.chainfire.eu/310/SuperSU/UPDATE-SuperSU-v1.04.zip) in order to gain root in the first place!... (you see the paradox!).

Hey guys,
I just bought the nexus 4 from a guy and its working awesome. The only "problem" I have is that the guy before me was playing around with the nexus. And now I have a locked bootloader, no SU binaries/root but CWM?? Is it possible to have CWM with a locked bootloader?
Anyways, i dont want to play around with it because the original store that sold this nexus will blame me for playing around with it if something actually happens.
So can i update it to key lime pie when it comes out without any problems?? Or can i remove CWM without unlocking the bootloader(i have alot of apps)?
Thanks

You can flash a ROM and then relock the bootloader. Just unlock it and start again
Nevermind

It's better to go back to 100% stock so you know exactly what's been done
You can always use this if you're rooted. https://play.google.com/store/apps/details?id=net.segv11.bootunlocker

I have pacmanrom installed on my device.
The issue is my headphone socket not software related.
So, will they accept a return or do I have to do some resetting process?

It's always safer to return to stock, if doing warranty stuff. Just do a nandroid backup, return phone to stock, send to Google and when you get it back, just restore your backup.

I'd use this toolkit, it's pretty easy to use:
http://forum.xda-developers.com/showpost.php?p=44984820&postcount=1951
or you can download stock image manually and flash it with fastboot, then lock your bootloader.

Flash a Nexus 4 factory image from Google: https://developers.google.com/android/nexus/images#occam
It will overwrite the bootloader, recovery, and /system, therefore wiping the device of any customizations.
Don't forget to also relock your bootloader at the end: fastboot oem lock
