Considering selling Nexus 7,need help.

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

Don't flash anything from another device.
Read the instructions carefully to install/flash a rom or kernel.

+1 That`s about the only thing to brick a Nexus

Don't do any formatting, and don't delete partitions. If you need a clean slate, do a factory reset or flash the stock image using fastboot.

The only thing you can't format is the bootloader that will brick it

Yep avoid flashing stuff for other devices. Most things will be recoverable but some can brick it. E.g. recoveries
Never ever use the command fastboot erase bootloader as this will 100% be a brick
I haven't seen anyone do it on the nexus 4 however i have seen people do it on the nexus 7

Error downloading updates!

Hello everyone!
My dad's nexus 4 hasn't been downloading updated recently. Whenever he says update all, many errors come. Any ideas?
By the way, he's on official 4.3. Stock, Unrooted.

Stock encryption

Has anyone tried the stock encryption with android (4.2 and above possibly?)?
I'm wanting to encrypt my phone but I've heard it can slow it down, which is obvious, bit is it notecebly slower?
In order to remove encryption for good on the device, do you need to factory restore?

On my Galaxy Nexus I didn't notice a slow down and yes the only way to remove it is a factory reset.

Nexus 7 lagging after update 4.4.2

Hi guys sorry if the thread already post before. My nexus has 4.4.2 rooted and already install twrp. I play game a lot on my nexus 7. But after upgrading to newest ota feel so lag when i try to play shadow gun dead zone. Is there any way how to fix it. I thought it was my wifi problem but when i switch to my old motorola phone it works like a charm.
Thanks in advance

Go into recovery and wipe dalvik and cache.
If that doesn't work, a backup of your apps to your pc hard drive and then a factory reset usually helps, but do the dalvik wipe first so you don't have to reinstall your apps and see if that works first.

But did the flash do a wipe of everything? If so, that's probably why. I'm on stock 4.4.2 and I don't have lag.

I wipe dalvik cache, and data. I m afraid to wipe system. I m not familiar with twrp. So only wipe does thing.
My nexus had a soft brick before when i update to ota and thats give me nightmare. So what would you suggest, do i have to wipe again dalvik, data system? Sorry for noob question but the lag just still there after on day flash from the rom.
Thanks
