need help.

I have no idea what i did, but my Nexus 7 formatted every file on there, there's not even a rom it can boot into....I can boot into recovery, but I have no idea how I can bring a file and load a rom on Nexus 7 because I can only get to three things..bootloader, recovery and google (unlocked) that's stuck there because of no rom.
using nexus 7 toolkit...but i'm probably doing something wrong...getting device not found.
can someone give me a noob guide on what i can try to fix this

Use the flash back to stock option with device will not boot checked on wugfresh toolkit

Did you try installing the driver package that comes with Wugs?
Its sounds like it isnt finding the drivers to me.Are you using a custom recovery or the stock?
Try using Odin and see if it recognizes it.

i thought odin is for samsung devices...where do i download one that works with N7?
I'm trying to install drivers, but it's not doing anything but opening up pictures with how to install in Wugs.
using wugs, it does pick up as grooper under device manager, but doesn't show on the MY COMPUTER section
not sure what you mean by recover or stock, but i can get into Clockword Mod Recover 6.0.1.0...does that help?
**tried odin 3.7 but it isn't doing anything

LOL sorry I got a few devices and 2 out of 3 are samsung.
Maybe try to install the drivers in the toolkit here http://forum.xda-developers.com/showthread.php?t=1809195 ,if you can get a image on there you should be able to flash it with Clockwork if you select install from zip.
I dont suppose you made a backup with Clockwork?

If you can get adb working you can easily flash it back to stock by following this http://forum.xda-developers.com/showthread.php?t=1907796

how do i do this when i can't boot into android
Driver Installation
This seems to be the most confusing part for many people. Be patient and thoroughly read all the instructions.
Enable usb debugging on your device (found under Settings > Developer Options)
NOTE: Since Android 4.2 the Developer Options are hidden by default.
To enable them, go to Settings > About Phone, and tap on build number around seven times. A small dialog will appear letting you know "You are now a developer!"
Install the abd driver - detailed instructions for installing or upgrading and existing driver on your version of Windows can be found at http://developer.android.com/tools/extras/oem-usb.html
Once the driver is installed open a command prompt and change directories to <your sdk directory>\platform-tools (see #2). From the command prompt run "adb devices". This will list any adb-capable devices that are connected to the computer by their serial number assuming your drivers are installed correctly. Recap:
Code:

can't figure it out....

Did you install the drivers from the nexus toolkit?
And maybe try a reboot of your pc,and try unplugging usb and replugging while in fast boot.
Also check in CWM and see if a backup has every been made even if its old, its better than where you are now.

there's no backup of anything on the nexus...everything got wiped somehow. nexus 7 toolkit keep tellingthe resource loader cache doesn't have loader mUI entry" whichs tells me it's ok..
adb: unable to connect backup
unplug / reboot / different ports...basic pc stuff already done

Maybe try using a different cable,Other than that maybe try a different pc and see if it loads a default driver to at least give you access to put a zip file on it to flash,could be your driver is corrupt on that pc never heard of it installing a nexus as grooper.
Besides that I'm at a loss.
Best of luck,hopefully you get it figured out.

so...i've tried the following already just to make it clear...
i already tried all the basic pc things
-switch usb ports
-reboot pc
-use usb2
-use usb3 ports
-use a different computer (one 8, one XP)....both...i don't really know what to do cause instructions seems to be mostly in 7 and/or just not working on 8
-rebooted asus n7
if someone can give me step by step, noob guide...instead of saying try thing / that, it may help me.

Try this to get adb working it was a fix for this guy. If adb works you can flash stock images.

I had exactly the same problem. I was able to restore mine to stock 4.2 without ever having the Nexus 7 show up under my computer. My understanding is that it isn't supposed to show up there unless it is booted into android, but I could be wrong. Anyways, just try downloading the stock N7 firmware and installing with the Unroot and restore stock option in the Wugfresh Toolkit, and if you want root and custom recovery back, simply use the option to reroot and follow the instructions. That's what I did and it worked like a charm.

Need some help installing drivers

So I got my n4 last week and I've been trying to unlock and root it to no avail. I've tried using the toolkit as well as using the method indicated in another thread on xda. I keep getting errors when trying to install the drivers.
I've been able to get the adb driver installed on win 7, but not the fastboot driver (using the toolkit).
I've even tried installing the drivers using the toolkit on a VM running xp without any luck.
Could someone please help me out with this? I remember having similar issues when rouoting my captivate, but I was able to use my work laptop to install the drivers (I don't have admin rights anymore).

A) Proofread.
B) Reboot into recovery and plug the phone into the computer. Go to device manager on your computer, look for the USB device with the yellow exclamation point, update the driver. Reboot your computer.

A) Wow that was bad, corrected
B) No devices were displayed in device manager when I booted to recovery. By the way, when I tried to update the drivers in fastboot mode, I kept getting errors.

Perhaps an earlier driver needs uninstalled? Check this thread: http://forum.xda-developers.com/showthread.php?t=1992345

I tried that driver, that is the driver I referenced in the OP, sorry for boy linking.

I was actually referring to the comments in the thread. A ton of people had issues installing. I thought you might try some of their methods.

[Q] Soft Bricked Nexus 7 can't install proper fastboot drivers

My N7 is soft bricked. I was installing a ROM but the file was corrupted. I can't perform a nandroid restore because I can't get into recovery. I'd push a new recovery via adb but my computer won't recognize my N7 in fastboot. I've tried installing Universal naked drivers 0.72 manually but it oesn't work. What else can I do?

There was no need to open a new thread... And you still haven't told us what os your computer has. Anyway, I personally use the official drivers from the Asus website.

Soft brick but with no adb connection on bootloader

Ok, tired of waiting for the OTA KitKat update for my Nexus 7 2012 tablet, I downloaded the OTA update and sideloaded it with adb. Got a status 7 error and now it's stuck on a bootloop. Thing is, my Windows 8 laptop won't recognize the device anymore (code 43 error on device manager) when on recovery or bootloader. There's even no way to instal google's usb drivers or anything because it says the device malfunctioned. I downloaded the factory image but, obviously, can't sideload it or do anything with it.
Please give me a hand with this, I'm really desperate.

More detail would be nice. What did the bootloop go between? Had you installed any custom recovery like CWM?
Are you still able to access fastboot mode?

Sorry, wasn't sure what you needed. The bootloop esentially goes from recovery to off and then to recovery again. I am able to go to fastboot normally (power and volume down when off).
Wanting to root the device a while ago, I unlocked it and rooted it whitout issues. Since the 4.3 update though, it was a little more difficult to root so having no time to research I just left it at that. That's all that was done to the Nexus 7. No Custom Recovery, no ROM, no nothing. Now, waiting for 3 weeks for KitKat, decided to sideload the OTA update (I did check the version was my device's version) the status 7 error appeared and all hell broke loose with the computer not recognizing the device.

Well, since you still have access to your fastboot menu, there isn't anything to worry about. Once you resolve the driver issue, you must be able to re flash the image.

Yeah, that's what relaxes me a bit, but I can't seem to fix it for 20 hours straight. I use this for studying.

Well, I suggest using another computer (a friend's or relatives') or installing a Linux distro like ubuntu. Oses other than Windows usually don't have such problems. I suggest you download something called adb gui which as I recall did a pretty fine job of 're installing the drivers for me.
But then, please do correct me if I'm wrong... I think that you must first use the device on adb and get the drivers installed and then only can you use it by the fastboot interface.

I used Wug nexus root toolkit to install drivers (windows 8.1) there are clear instructions (if you click manual or something similar) how to get drivers to work.

Yeah, actually I did use the toolkit when I was trying to update to KitKat. Thing is, it doesn't work since the bricking occurred.
Yeah, I'll try on another pc, and I'll keep you posted.
Thanks

I'm having a very similar issue. Mine will try and bootup but just stays on the boot animation for as long as I could wait, 10 minutes or more. bootloader is working just fine and I should be able to use fastboot commands to resolve the issue. I'm not able to get to recovery for one reason or another, but it is updated to the latest CWM.
The trouble I am having is the same though. I cannot for the life of me get the drivers to work. I have tried it on one win8 pc, and one win7 pc. I haven't tried any of the toolkits to help with driver installation on the win8 pc yet. I also have another pc that I am going to try also has win8 on it as well. If you can get the drivers installed, please post a reply as to what you did here, and I will do the same, from what I have been able to find you and I aren't the only ones that are having this issue.
If the windows route doesn't work, I have a copy of Ubuntu that will be going on the computer to see if that resolves my issues. Also, may want to try another cord, I have a couple that are charge cords only. Once getting the drivers working it should be a very simple job.

Do you think that will be easier? I've not done a whole lot of work with android using linux. I have experience with both separately, but not together. any insight would be fantastic. Have you tried running a linux distro yourself to solve your issue?

It pretty much cancels out any problems with drivers.
It is easy to do.
It takes 5 minutes to boot up and test? Try it for yourself

If I did have any driver issues, the first thing I'd do is reinstall drivers, and if necessary, Windows itself, because I like everything to be working perfectly.
But supposing that that was not an option and I needed my phone or tab real bad, ubuntu would be my first choice. Especially because the concept of installing 'drivers' doesn't exist in ubuntu.
No, that should be fine. As long as you have used terminal before and you know the basics.

I appreciate the advice, I will give it a shot this evening, and let you know if this works. I'm sure that it will.

Alright, so I got SDK up and running on Linux! It was a little bit of a pain, but it installed just fine. Once I got it all installed I was able to see the nexus 7 through fastboot! From there I was able to reinstall the bootloader. Then was able to get to recovery to do an adb push to get a rom of 4.4 on to it. 4.4 installed just fine. All problems are fixed Good suggestions guys!

Bricked Nexus 7

Hey guys,
a few hours ago I tried flashing the new Ldroid Rom onto my Nexus 7. After flashing the rom my tablet took ages to boot up and after the bootup it said i had to enter a password to encrypt the data (i never set encryption). after entering a random password android reported that the password was right but the data corrupt and i'd have to do a factory reset. after entering twrp i realized that the device couldn't mount anything except system. i wiped/formated everything except system and tried booting into android. this time i was stuck at the google logo. after entering recovery mode again now twrp couldn't mount system and sdcard. so i formated both and now i'm here with an absolutely empty nexus 7. i tried to use adb sideload to flash a new rom but my pc doesn't recognize the device and neither does fastboot. i tried reinstalling adb and fastboot drivers, i used universal drivers, i used drivers from toolkits, i did many many pc and tablet restarts, i reinstalled android sdk several times, i used different adb/fastboot locations, i even tried using a different pc trying the same steps. no change, only thing i get is that the tablet gets recognized by the device manager as an adb/fastboot device, nothing more.
Does anyone of you know a possible sollution for my issue?
Thanks in advance
P.S.: i've been researching the internet for this issue for the past hours and couldn't find any sollutions, so please don't say stuff like "use search function"
P.P.S.: My other devices get recognized without any issues with the same cable.

I would suggest using wugs awesome software you need to make sure all partitions are wiped and repaired to which ever format you are trying to use ext4 or f2fs and through wugs you can flash new ROM through fastboot wigs has save my ass a few times one should not try to do tedious tasks after a long night of drinking hope this helps let me know if ya need more

Alright I used my macbook for adb/fastboot and there it somehow recognized my device and I could use fastboot to do a factory reset. I still don't know why two independent windows systems did not recognize my Nexus 7 but I got it fixed. Anyways thanks to everyone who tried to help me in this thread!
