The factory image is not a flashable zip. You'll need to either flash it via fastboot or you can use Wugs toolkit. Just Google "flash factory image Nexus 7", you should be a able to find a tutorial.

Hi,
I'm on paranoid android 3.69 and I'll probably upgrade to the N5. So my N4 is most likely going to my parents. I was wondering how to go back to stock. When I check for a system update it says 4.3 is available. Would that be the way to go or do I need to download the stock rom and flash?
Best and easiest way to return to stock, in my opinion, is to simply download the factory image for 4.3 for Mako. Extract the factory image and load your phone into fastboot mode. Afterwards, open a command window in the extracted folder to flash each .IMG.

this.
flash original factory image from google 4.3 and flash radio.img, bootloader.img and image.zip in bootloader mode.
If flashing the factory images in fastboot have you worried just use one of the toolkits
Why can't I seem to find the stock recovery .img file for this device? I have searched hi and low. Can anyone help a brother out?
Here are the Nexus factory images https://developers.google.com/android/nexus/images#nakasi
Be careful to choose the proper N7 version (2012/13, Wi-Fi/Mobile).

Hi, satur9ine...
You don't specify which Nexus 7 (2012) model you have... the WiFi only model, or the WiFi & 3G model.
Reason being, is I always keep a copy of the stock recovery close to hand... but it's extracted from the factory image intended for the WiFi only model... and I'm not sure it would work correctly if flashed on a WiFi & 3G Nexus 7.
Anyway, here is my copy of the stock recovery from Jellybean 4.3 (build JWR66Y) for the WiFi only Nexus 7.
https://dl.dropboxusercontent.com/u/37483979/recovery_img_nakasi_jwr66v-y_grouper.zip
Download to your PC, and unzip the recovery. img file inside.
Fastboot flash it with fastboot flash recovery recovery.img.
As I've said... this stock recovery was extracted from the Jellybean 4.3 factory image designed for the WiFi only Nexus 7... so if you have the WiFi & 3G model, I would suggest you download the Jellybean 4.3 factory image for your device, as advised by Erovia, and extract the stock recovery accordingly.
Hope this helps.
Rgrds,
Ged.
Edit: Thank you above poster!
I don't want to do a factory restore, though. I just want to flash the stock recovery via fastboot.

That's exactly what that is. It will not factory reset your device. Just be sure you are using it on the right Nexus 7 and version as mentioned.

Same here. Goo hasn't worked for me for several months now. Pretty much given up on it.

Hi, joshag....
If your Nexus 7 is already rooted, you can use the apps, Flash Image GUI or Flashify to flash a Custom Recovery directly from the Nexus 7 itself.
Just install one of them (personally I prefer Flashify)... download the TWRP Recovery Image file appropriate to your particular Nexus 7 (links below)... and then use Flashify or Flash Image GUI... the on screen instructions are pretty self explanatory, just ensure you pick the FLASH RECOVERY option, and then navigate to the folder on your Nexus 7 where the TWRP recovery image downloaded to... (usually the /download folder).
So... no PC or fastboot required... just a rooted Nexus 7. (If you aren't already rooted, you're out of luck I'm afraid).
I use this method myself quite frequently, particularly when I can't be bothered booting up my laptop.

That was easiest/most concise explanation.

Hi,
My Nexus 7 3G 2012 was rooted, stock rom 4.3 but I've deleted some APK in the system partition. Now my Nexus 7 received an OTA update for the KitKat. What is the quickest way to safely update to the 4.4 while maintain all of the installed apps and userdata?
Thanks
1. Download the official KitKat image files from Google
2. Extract system.ing and boot.img from it
3. boot into bootloader
4. fastboot flash system system.img
5. fastboot flash boot boot.img
6. reboot your system

Tks for your reply.
So all data and installed apps will be inact?

Yes, I am doing it always in that way, because I have a rooted system and normally there are often problems with applying the OTA. Flashing boot and system will keep your data and apps which are located on the data partition. If you want to be really sure to have a clean system, I would also flash a custom recovery, boot directly into recovery and wipe dalvik-cache, but this is not really needed.

This is interesting and really new to me.
Could you please precise, which tools you use? A little how-to would be very helpfull to get along with the bunch of possibilities coming with TWRP and/or wugfresh´s toolkit.
I am using no tools / toolkits as I want to have full control on the flashing process. Probably you might want to have a look at my blog. Here I described the update process already some time ago (not to go to 4.4, but the steps and the mechanism are the same).

Ok tks for your response.
However my friend confirmed that he updated successfully to 4.4 via OTA while rooted.

I have used this method every update. Only takes about 5 minutes.
It amazes me all the convoluted methods and bricked devices that you see, when if people would do a little research and had a little understanding of what they are doing it would save them a lot of grief.
All I can say is thanks to the person who wrote this simple how-to.
Now I will get off my soap box.
Hi, I booted into TWRP recovery mode to attempt updating my rooted Nexus 7 from 4.2.2 to 4.3. I wiped system, dalvik cache and cache. I also (stupidly) wiped data and internal storage too. Now I cannot turn on my Nexus 7 fully, it only shows the Google insignia with the unlocked boot loader icon below it.
I can boot into recovery mode and I can USB host, I tried copying a zip of the stock 4.2.2 ROM for Nexus 7 wifi onto my flash drive and tried flashing under the "install" section on TWRP but it always fails (I do not know why).
I cannot connect my Nexus 7 to the computer. Can anyone help me out, please?
Use adb side load in advanced settings
adb sideload nameofrom.zip
adb sideload gapps.zip
Reboot
Profit

Either flash a custom ROM from recovery or use the Wugfresh toolkit to flash a stock ROM.

Agreed, the toolkit works like a charm.
I had also deleted the whole Os and fixed it with the help of the toolkit.
Not sure why folks keep telling you to flash a custom rom when you ha e clearly stated that it fails. So, heres my two cents......
Since you already wiped the internal memory and there is no chance of data loss, just download the stock image and fastboot back to a fresh system. And for gods sake, dont use wugs. Just use good ole fastboot. There is a very easy how-to in the stickies of this section. This forum is full of problems arising from toolkits, that could have been easily avoided by fastboot.

I SECOND that use the toolkit from wugfresh for this.
ADB sideload and Fastboot is a real pain with TWRP don't know why the file does not get pushed at all.
Save yourself time and just use the toolkit if it's a Nexus device if Samsung find a similar toolkit tool
The site for toolkit is wugfresh . com ( no urls so the space )
Hope this helps someone
Good luck
