SOD and no root and unable to connect to a pc!

Ok so I was running taboonay 3.0d and I thought I'd have a go at Thor's rom. Flashed it wasn't really into it few things missing that I like in taboonay. So I then restored my back up. All hunky dory.
I then flashed a zip for scrillax v8 bootloader. It seemed to work fine, tablet boots up and rom running fine. I then tried to get to recovery and it's just not happening. Acer recovery says it cannot get root access. When I reboot I can get into the bootloader menu but none of the commands work. I can't get into the recovery menu at all no matter what I do. So then I figured I'd give Blackthund3r's root tool a go. Got everything ready on the pc including latest acer drivers. Now the tab isn't showing up on the pc either. I know some others have had similar problems but no solution was found in the other threads and considering that I probably screwed up badly somewhere along the way I thought I'd start this thread where you can all point out my ignorance and stupidity without bothering anyone else :silly:
Any help?

Any advice at all would be great, I have reinstalled drivers for tab but still no go! I'm on a old xp pro laptop. Everything else connects to the usb port and the cable is working fine

If you can't get to Recovery, you will need to reflash that.
But first thing is first. And that's the driver issue.
With the tab plugged into the PC, go to Device Manager, and see if it reflects there. If not, you will probably have to reload the drivers. You have a choice, which is the Acer Driver installation, or you can try the Google USB Android drivers. Generally I have had not much luck letting windows search the PC, so I usually install them manually. You can either;
a. Direct device manager to look in a specific folder for the google drivers, or;
b. In Device Manager, when you choose update drive, use "select from list" and see if the acer drivers show up there.
Generally, when you install the acer drivers, you should "right" mouse click the install file and select "run as administrator".

Thanks md will give it another go
My device manager has no option for select from list or update drive, just scan for new hardware. Nothing shows up for acer.

Ok, now I run Win 7. But XP should be similar.
Are you saying in device manager, you do not have a device with an exclamation mark when you plug the tab in???
If you do, then right click the exclamation mark, select properties. Then the Tab "driver". Next, select "update driver". Then, "browse my computer for drivers". You should get the option to "select from a list".
If your PC does not detect the tablet at all when you plug it in, then it';s a different issue. It's what we call a USB Brick. At first guess. Usually easy to fix on the 500.
Can you start your tablet in APX mode? hold the pin reset, press and hold pwr. Count to 3, and release pwr, then 1 second later, release the pin reset. You should have a black screen with the pwr lite on.
I'm thinking you might want to do the manual flashing of the bootloader + 1.7.3 recovery. Obviously the bootloader V8 flashed, or it wouldn't work at all. Civato has instructions for manual flashing of the bootloader and recovery. Note that I HOPE you wrote down your UID number somewhere. As you will need to convert it to the SBK.
MD
EDIT. One more note. When you boot to the bootloader menu, in your case, probably the only option that will work is "fastboot mode". When you select it, the menu should go away, and it should say "fastboot mode". Then plug into PC and see if windows detects it in device manager. If so, you can fastboot a recovery image to it. Note, that for fastboot to work, you must have the Android SDK installed on your PC. Because you will have to run the fastboot commands from a command window. But for now, check to see if you get to fastboot mode on the tablet.
Sorry I can't spend a lot of time, as it';s late in moscow. Job tomorrow. But Skirlaz_CZ can give you the commands to fastboot a recovery in his bootloader thread.

Thanks MD I can get into fastboot mode so I'll try that one first. I didn't write and numbers down unfortunately. I was following a thread on tegraowners to install the bootloader which made no mention of making records( I'm a simpleton that needs to be led by the nose)
I appreciate your input

Ouch! No UID numbers. That hurts. Look in your old CWM recovery backups (if you have) on your EXT SD Card. If you were at one time running a more recent version of CWM, You might have them in the recovery folders. The more recent recovery programs in the backup folders, it's called UID.txt. You have to have this if you use NVFlash. No way around that.
With Fastboot, you don't need it, as you will fastboot the recovery image. If successful, that should allow you to boot to recovery, and flash one of the custom roms. Make sure you do your wipes as in the Rom install instructions. I use CWM 1.7.3 (I've been too busy to try EZTerry's or the TWRP versions. But CWM works good so far.
If not, well, there;s always the update.zips to get a stock ICS on your tab.
Either way, we'll get you running, so don't worry. Just takes a little time between time zones, work, and family

You're not wrong there! I'm doing the whole ikea/home improvement thing with the family today. I'll try the fastboot later
Again I really appreciate the help.

Ok MD so the fastboot doesn't work at all. I installed adb using knives and forks and that couldn't pick up the tab for drivers installation. My head is wrecked! checking backups for numbers now
0x037c62074 and a few more got it
Edit: farkin idiot I just noticed the sdk requirement! Will install sdk and give fastboot another whirl

HA HA! Yep, gotta have the SDK for ADB and Fastboot. I posted some instructions yesterday about flashing recovery via fastboot.

You should be able to do it if you already have V8 Bootloader.

Nice one MD going to try it out.

Thanks for all the good work. I was actually following another thread stupidly when I should have been following yours.
MD - was away for a few days, just back but have had a few beers so not doing anything stupid tonight. Got sdk installed.

MD - Have you a link to download cwm 1.7.3 img? The download link in tegra won't work for me.
edit - nevermind I usedthe recovery skrillax suggested in his thread. Problem is the pc is not picking up the tab at all. Just says waiting for device

Sorry I was away. Did everything work ok for you? All running? (been trying to chase down my rom issue)
If it says "waiting for device", then you need to check your device manager, and make sure the correct driver is recognized. (APX, Fastboot, Recovery, Download, etc). Usually, I can change drivers while this is happening, and the process will complete.
MD

ok I don't mind admitting that I'm totally lost here. Nothing resembling the tab is showing up device manager so how can I check the drivers?I've been playing around with device manager for a while now and I can't find any way to do what you suggested
I've uninstalled and reinstalled the drivers again and again. Nothing! Could it have anything to do with me having a gateway? I wouldn't think so because they're the same inside.

Righto, no matter what I do the tab won't show up. Obviously can't check the drivers without the device showing up so I really am at a loss.
Even if I try the manual flash from civatos thread I will still come up with the same problem. No device no can do

be worth checking you still have usb debugging enabled m8
EDIT: The only other thing i can think of is to put yr tab in apx mode manually (press and hold reset button then press and hold power button, when the pwr lite comes on count 3 seconds and then release it, hold reset another second and then let that go) - you should have a black screen and power lite is on) now connect yr cable and see if the pc picks up the acer boot/recovery driver under usb controllers .
If these drivers install then I'd attempt a rollback to HC using an EUU, at least this method depends on yr pc not seeing yr tab. I'd only attempt this tho if the boot/recovery driver is installed and listed in dev. manager.

Ok ok boot/recovery driver? You've lost me there chap! Xp device manager is showing nothing tab related. Tell me what to do and I'll give it a blast.
I'm using the regular usb slot as opposed to the mini cause I've no mini cable. That should be ok right?

Nexus 7 Stuck in Boot Animation Loop--Please Help

***TL;DR AT THE BOTTOM***
*^*EDIT 2!!*^*
Utilizing Cerberus, I was able to get passed the boot animation into the lock screen, though the Launcher is, for all intents and purposes, nonexistent. However, I was able to install Nova Launcher and can go to a home screen just fine. THIS IS NOT SATISFACTORY. I want to get back to STOCK Launcher, but it apparently does not exist anymore. I've managed to copy over my backup of Launcher2.apk, but it still refuses to acknowledge its existence. Can I get an update.zip that'll reinstall the default launcher from someone? I can boot into recovery via ROM Manager now I suppose!
+++EDIT!+++
+++~~~I have discovered that my problem is not the device being stuck in boot up, but that the boot animation will not cease--as +in the device is actually powered on, just displaying the boot animation like a screen saver. I cannot boot into recovery as I get +the Google splash screen and it never goes anywhere, my bootloader is freezing every time I plug it into my computer, and the +drivers will not install. My computer cannot detect fastboot and I can't connect to the Nexus via adb either. I CAN access internal +storage but that's about the extent of what I can do.+++~~~
Long version:
I decided I wanted to change the App Drawer icon from stock to a Nexus X that inverted its colours when pressed. I found the icon, converted it to png, inverted the colours and everything was going fine.
After a while I finally managed to find the right icons to replace in the system apk file "launcher2.apk". "ic_allapps.png" and "ic_allapps_pressed.png" or something very similar. I simply replaced them with my two icons, installed my modified launcher2.apk, and that was it.
Immediately, my home wouldn't open at all, no matter how many times I pressed the home button. It just would not exit the app I had up. So I started backing and ended up in an infinite back loop. I powered off the device, waited a minute, and powered it back on.
It came to the usual "Google" screen with the unlocked symbol at the bottom, no problems. However, then it started playing the boot animation. The boot animation never stopped. It looped infinitely. I tried resetting the tablet a few times for the same result. It was after 3 am and I had to get up for work in 4 and a half hours. I thought that maybe it was gonna take a while. So I flipped the Nexus over while it was "booting up" and went to sleep.
When I woke up and checked the tablet at 7:30, it was STILL booting up. Obviously I had screwed something up.
Now, stupid me, I had never flashed CWM recovery on my Nexus 7 (haven't had it that long), so all I'm stuck with is STOCK Recovery. I'm pretty sure I can rescue the Nexus by factory resetting it or something similar, but I'd rather try to save it first. All I modified was a LAUNCHER application, so I'm pretty sure the current state of the Nexus itself shouldn't be too far gone. Is there any way to save the Nexus WITHOUT a data wipe? And if the data wipe DOESN'T fix my problem, is it possible to somehow flash a stock ROM through stock Android Recovery?
***TL;DR***
I modified launcher2.apk and replaced "ic_allapps.png" and "ic_allapps_pressed.png" with two customized .png files (which I renamed to their appropriate file names). Now my Nexus is stuck on the boot animation indefinitely. I would like to save all of my data, as a data wipe would be inconvenient, but if I must do one I shall. I am on a stock ROM and a stock Recovery. If a data wipe/factory reset will not save my device, is it possible to flash a stock ROM through regular Android Recovery?
===Related but irrelevant to the problem===
Is it completely impossible to change the stock App Drawer icon to something different? I'd rather not have to get a different launcher app just to create a Nexus theme! I did a little more research and found that I should've modified the "all_apps_button_icon.xml" file as well, but I have NO idea how to do that.
Many thanks,
VonDerThWood.

As long as you can get into the bootloader you can flash back to stock using fastboot and the image from here

no need to flash back to stock, silly advice. just flash a custom recovery and flash a stock rooted rom. flashing a stock rooted rom will replace what you messed up on. dont wipe.

How can I reflash the ROM on stock Android recovery? Googling that returns CWM results.

He is suggesting you flash custom recovery with fastboot and just flash over top of what you did thru the custom recovery which you can do as well, what I suggested just returns it to factory state I don't see whats so silly about it I understand he wants to keep his data but worse comes to worse as long as you can get into the bootloader you're fine

youre right about if worse comes to worse. reflashing the factory image should be the very last thing to do, when all other options have been tried. im just trying to save his data

If you don't have fastboot set up you might want to give this post a look he describes how to get it set up.

I don't use custom recoveries and backup my data regularly with Titanium, so restoring after a reflash is really just an afterthought here, to each there own

The problem is not as it seems.
When I plug the Nexus into the computer when in Fastboot mode, it freezes the Recovery. I cannot select anything OR move the selection to anything else. The hell?
I noticed that when the Nexus attempts to boot up, the boot animation gets brighter.
__
Wait, when it attempted to boot up when plugged into my PC, AutoPlay recognized the device as Nexus 7. There is nothing on my screen but the boot animation, however I can browse internal storage.
I cannot, however, connect to it via adb apparently. ADB devices returns nothing.
____
Okay, the problem is NOWHERE near what I thought it was. The boot animation is replacing the lock screen/home screen/everything. I just received an email (I could tell because of the notification noise the tablet made). It is booting up, just not displaying anything passed the boot animation and ADB cannot detect the device. I KNOW it has USB Debugging mode activated and all, but what can I do now?

I usually make backups and nandroids but I've barely owned this device. ;P

Does fastboot detect the device?

Fastboot doesn't detect the device while booted up like this, and when I plugged it into the computer when in recovery/fastboot mode it not only froze the device, but fastboot wouldn't detect it.
I can get into the internal storage (just not the root of the device unfortunately). So what can one do when he cannot connect to the device via fastboot or adb, nor flash a custom recovery image because he can't access fastboot?
This is getting more complicated the more I dig into it. What the hell did I do?

Are you on the correct screen? I see how you are lumping Fastboot/recovery together, Fastboot is used on the screen with the android with his chest open after holding down the power/vol buttons from complete off , has version info/ unlock status in the lower left.. not sure if you can do that in the recovery but that is where I put the commands in

the freezing in the bootloader is a n7 bug. try a few times. try going into the bootloader then plugging in usb, and try plugging in via usb then going into the bootloader. try a few times, eventually you will get it.

You have to be in bootloader for fastboot to detect your device. Once in bootloader, open a command prompt where your fastboot.exe is stored and type "fastboot devices" without the quotes. If it detects it, it should list your N7's serial number.

Fastboot has the "Recovery mode" option but it just gives me the Google logo with the unlocked icon at the bottom indefinitely...which means I cannot access recovery either? Why didn't I notice this before? >_<

Tried 10 times by booting into bootloader first, then 10 times by plugging it in and booting into it while it's plugged in. This is a very...odd bug.

Now that I think about it, it DID say something about failing to install an unknown driver the first time I plugged it in. Let me uninstall/reinstall the drivers.
____
After reinstalling the drivers (and removing both of the Nexus7 specific ones), I also removed one named "Android", which, coincidentally, is the driver that the tablet is trying to install upon being plugged in. I have tried to reinstall it several times, but it fails each time, AND I just reinstalled the real Nexus 7 drivers.

The Nexus drivers won't reinstall now. I even went to Asus's website and downloaded them, but I have no clue how to install it in this format.
Is there a way to open/install an app through JUST the Internal Storage? If so, I have the stock launcher2.apk file right here...I just need to reinstall it! Damn, how can I get to the Root folder without ADB?

Whoa! Stroke of GENIUS!
I have Cerberus installed on my tablet. Since I know the tablet is booting up, just not displaying passed the boot animation, I decided to give it a try.
I started an alarm, which forced the tablet to the lock screen...I can open apps through the Play Store (as I got an update notification) and the like, but I can NOT get to the home screen.
I opened Total Commander via Play Store, but I can't do anything with it. The app that I used was NinjaMorph and I'm pretty sure the only way I can correct my mistake is through that app. What do I do?
Found NinjaMorph in the Play Store, it couldn't fix my problem. Oh hell.
I tried to copy/replace the launcher2.apk file I screwed up with a backed up one but TotalCommander couldn't do it. It was even granted SuperUser permissions. Attempting with Root Explorer.
Success! I have copied the original Launcher2.apk back into the /system/app folder. HOWEVER, I can NOT install it.
Managed to connect via adb! Things are looking up! Now, how to install this stuff...?
When trying to reinstall the launcher2.apk, it gives me the following error:
INSTALL_FAILED_UID_CHANGED
So I tried uninstalling it to no avail. Troubling.
SO! Now what? I am into the device, and any app I have downloaded through the Play Store is available to me, but I cannot go to the home screen. I need to reinstall the original Launcher2.apk!
Retrying NinjaMorph. It supposedly installed my Launcher2.apk. However, I still cannot return to the Home screen. WTF.
I'm going to install a different Launcher. Hope that works!
Success. I can now return home to Nova Launcher. HOWEVER...
This is not satisfactory. I want my STOCK launcher. Anybody know how I can fix this? The stock launcher is acting like it doesn't exist anymore. Is there a way to just wipe THAT data and keep all the other data on my device?? (Though I admit, I do like how I already was able to change my App drawer icon to my Nexus X <3.)

Edit: I see you resolved it. Good job! I'll just leave this here... :good:

You sound to be in Windows driver hell. If you have access to a Linux machine or someone who does, this entire driver mess can be avoided.
You can't install an apk via the MTP or PTP usb interface. You have a few options to fix this, but all depends on getting your drivers sorted.
Otherwise, grab the latest Windows USB drivers from Google - https://dl-ssl.google.com/android/repository/usb_driver_r07-windows.zip and follow these instructions to install them - http://developer.android.com/tools/extras/oem-usb.html
With the drivers installed and the nexus 7 plugged in, try adb devices again. Assuming you can resolve the driver issue, run
Code:
adb install path\to\launcher2.apk

[Q] Nexus 7 Booting Failed & No ADB Connection

Hi Guys
Another rooting/flashing noob here that's messed up his N7 sorry
I know there's other threads with similair issues but they all advise fixes involving using adb connection and usb debugging which I cannot do (explained below)
My device will turn on, it goes to the google logo with the green start icon, I can select and go into bootloader and recovery, if I press start it says booting failed in the upper left corner and will go no further.
My device is plugged in via usb, i have the latest rookit 1.5.5, and sdk installed etc, i also have the naked drivers and the factory images from google on my pc.
The machine came with 4.1.2 installed (nakasi-jzo54k).
To mess it up, somewhere in between updating to 4.2, rooting and unrooting it, and flashing it i must have done something wrong but being a happy button bashing noob I don't know what exactly...
And yes I also didn't make a backup of any kind because well I'm just a moron and lesson well learnt.
So yeah, I have no adb connection, can't go into debuging mode and it won't boot.
Does anybody know if there is anyway I can restore my tablet please? Any help would be hugely appreciated!
Many thanks

If you got half way through rooting, what has happened to your ADB?
Try the option "Return to stock and Flash stock image" try that.
What message does ADB give you etc?

Hi thanks
Well when I run 'adb devices' in dos the device does not come up, blank etc
but if in the advanced utilities section of the rookit it will reboot it and say connected etc when i try to boot/flash image for bootloader, system, recovery etc but always goes back to google logo and won't boo up, can still get into bootloader and recovery though
i fully rooted it and unrooted it, i tried to flash 4.1.1 to see if i could thats when this all started
if i try flash stock + unroot option (device is on/normal) sub option the rootkit tries to check adb status and says not connected etc which makes sense as dos won't detect it, if this helps in device manager its coming up as...
samsung android phone
android bootloader interface
so i that driver in rootkit to manually install the naked drivers in device manager and it will say they are up to date etc
so the advanced utilities section for boot/flash image will communicate but no other.....
flash stock root used to detect it but even then in dos it would give me the 'too many links error'

Hi thanks
Well when I run 'adb devices' in dos the device does not come up, blank etc
but if in the advanced utilities section of the rookit it will reboot it and say connected etc when i try to boot/flash image for bootloader, system, recovery etc but always goes back to google logo and won't boo up, can still get into bootloader and recovery though
i fully rooted it and unrooted it, i tried to flash 4.1.1 to see if i could thats when this all started
if i try flash stock + unroot option (device is on/normal) sub option the rootkit tries to check adb status and says not connected etc which makes sense as dos won't detect it, if this helps in device manager its coming up as...
samsung android phone
android bootloader interface
so i that driver in rootkit to manually install the naked drivers in device manager and it will say they are up to date etc
so the advanced utilities section for boot/flash image will communicate but no other.....

Have you added ADB to your envioronment varibles?
If not,
Control Panel -> Advanced -> Envioronment Variables, then add the path to your SDK folder to it, after the other variables (Variables are separated using ; )
Also, try to install the drivers, using Wug's method, thats THE ONLY ONE that worked for me, unistall anything to do with nexus before hand.
Goto Device manager, find anything that involves Nexus or Android.
Then Start the "Full Driver Method" on Wugs kit.
This should sort your driver issue.
Then the Nexus should be visible through ADB.
PS- Your adb isnt broken if its accepting the commands.
The reason your device isnt listed, is the Drivers.
You have driver issues, so try the what I just stated and let me know .

The first step in the full driver guide in wugs kit is to enable usb debugging which i cannot do though as it won't power on.......
I have added the environmental variabes before yes sorry, qbkings utube vids showed me how to do that
Just tried these steps
toolkit home screen, flash stock + unroot (softbricked bootloop)
then naksaki 4.2 jzo54k, auto download and extract.
it got to dos stage and i get 'Failed bootloader is locked'
??? thanks again

OK, more help please, been hanging for5 mins lol

Issue Fixed I think, he PM'd me.

Unlocked but... what do I do now?
Newbie but old or old but newbie - With the need and not just a curious want, to be able to "rename" my Nexus 7 v1 so I can see a friendly name in my old DD-WRTed Linksys GL, I finally had enough gumption to try rooting this tablet.
So, I was excited that when I used Nexus Root Toolkit v1.6.8 on my Nexus 7 v1, following the "easy and visual" steps, I actually managed to unlock this device. But when it came to the "root" part, the ADB repeatedly failed to recognize this tablet. I tried all the suggested steps and remedies, but so far, nada.
The tablet now boots past the white "Google" with an unlocked icon at the bottom, but nothing beyond thea big white "right-arrow" on the screen. I can choose a Wi-Fi signal to connect to, but that's it.
This is my first tablet and I have been playing with it for the past 3 months. I know people here are more than willing to help, so thank you in advance.
BTW, I am not that young to spend hours way past sleeping time to scour for answers and piece it together.

This worked for me...
Download the image file for your device which you can find at the Google Developer's site
Copy the uncompressed files from the image archive to the platform-tools folder of the Android SDK
Use the up and down volume on the device to get into bootloader mode. Connect the device to a usb port.
Open a command prompt in the platform tools folder and run the flash-all batch file to load the image to your device. After a few minutes I got the happy X logo to get me back to a blank slate.

[Q]Bricked ?

This is what happens :
1. When I normally turn my N7 on , it goes throught the google logo and gets stuck on the ROM logo .
2. I can get into the bootloader when the USB is plugged off , but i cant get into recovery it just gets stuck on the google logo .
3.If I plug my USB in while in the bootloader the bootloader gets stucked and i cant move around in it or flash anything , but my PC recognize that an android device is connected . (if i get into the bootloader when the USB is allready connected it gets in the bootloader main screen but i cant move) .
So i cant flash , get into the rom or return to stock .
ANY IDEAS ?? please help me :crying::crying:

Bump

Definitely not bricked since of powers on. Fastboot flash the stock image and you should be good as new.

Strange, it shouldn't make a difference whether your USB is plugged or not when trying to get to the recovery.
If you get into the fast boot menu or "boot loader main screen" and you press the volume down button a few times you get no response? Sometimes it takes a few seconds for mine to switch to recovery,etc.
Also, what caused your tablet to get stuck in that state?

If I press the volum dowm bottom while on fast boot menu I can move around the menu if the usb is plugged off , but I can only shutdown or restart the fastboot since the start and recovery options just gets stuck on the google/rom logo if it is plugged in I just gets stuck in the menu and I cant even scroll . yea I waited about half an hour on the google logo trying to get to my recovery and nothing happened .
I JUST DONT KNOW WHAT I DID ! I really dont ! I am an experienced flahser and had been so for almost 2 years now ! I just left my N7 on the table and didnt touch it at all for a week and when I tried to turn it on after that I just got that prob . but I did nothing related to flashing or so - it just happened by staying at the table !
any help ?? PLEASE
I CANT RETURN TO STOCK , if i plugg in the usb fastboot gets stuck .

have you tried charging it on the wall charger to make sure the battery has got a full charge, don't know, just throwing out options

Hmmm, well at least you're able to boot the tablet and get to fastboot menu so its not a hard brick. Sounds like a corrupted partition of sorts if you can't get into ROM or recovery. Someone with more expertise might have a possible solution. I wouldn't lose hope yet.

yes , i did charged it to full batt .
i can get into fastboot but not rom or recovery and when i plugg in usb i have no fastboot , doesnt that mean i wont ever be able to flash ?
if i will make a vid of the prob it will help ?

Get to boot loader and do
fastboot flash recovery C:\File path to recovery on computer
Once you have a recovery installed you can push a ROM to your Nexus via adb.

Or you can always use wugfreshs toolkit and click flash back to stock option and check device won't boot, the same thing happened to me awhile ago and the bootloader problem is cause you have the old bootloader the knew 4.13 bootloader fixed that

It says you can get to the boot loader with the cable unplugged. So get to the boot loader and then plug in the USB.

I really appreciate any kind of help, but why even write and answer when you didnt even fully read the question ?

Lol just calm down man we're all just trying to help you!
Now, you need to get your N7 into the bootloader, it does not matter if you can't navigate the bootloader on your N7. Once in the bootloader, connect the N7 to your computer with the USB cable.
Once you're connected, make sure you've downloaded the Android SDK and open a command prompt. Navigate your command prompt (make sure you ran that command prompt as administrator) to the "platform-tools" directory.
Once in the platform-tools directory run the following command without quotes:
"fastboot devices"
It should return the serial number for your device, indicating that fastboot sees your N7 and can work with it.
After that type
"fastboot flash recovery *.img"
You'll need to head to clockworkmod.com to download the N7 recovery image. Place the downloaded image in the platform-tools directory and replace "*.img" with the filename of the recovery image you downloaded.
That's it! Unplug your N7 and go into recovery, and sideload whatever ROM you want!
Let us know how it goes!
PS: If fastboot devices shows nothing, we have a bigger problem...

Its hard to be calm then you new N7 is dying :/
somthing like this ? (pic attached)
If i did everything like you said it means i do have the bigger prob help me!

OK. Next thing is to ensure your N7 is properly detected in Windows.
Just head to the device manager. You should see Original Android Interface or something along those lines.
Report back with a screenshot, those are very helpful!

Here you go (attached) ! you have everything you need mate ?
I really appreciate the help ! :good::good:

I had similar issues and was able to get back to stock using WugFresh's Nexus Root Toolkit. Highly recommended!

From the same command Window, in the same platform - tools directory, does adb devices show your device?
I'm not the lowest of the low, but I am the slowest of the slow.

[Q] Stuck in FTM Mode?

Hi folks,
My wife dropped her 2-week old Nexus 4 which caused part of the front glass to crack and portions of the touchscreen to be dead, so we had to send it into LG for repairs (at quite a price tag). Fine.
So we get it back, I turn it on, and it's in something called "FTM Mode" (file transfer mode, I think)? I can't seem to get it out of it.
Things I've tried:
Rebooting (have to hold the power button down for 5-10 sec).
Factory data reset (the settings are available through the notification menu in FTM Mode).
In recovery mode:
[*]Start (goes right back to FTM Mode)
[*]Power off (duh)
[*]Restart bootloader (gets me right back to the same screen)
[*]Recovery mode (gives me a little android with its stomach open, a red exclamation point, and says "No command.")​
I attempted LG support, but they asked me to do a few of these (after asking me to hit the "home" button...), then told me to mail it back to them because they probably have to flash it.
So, the obvious question: how the hell can I get out of FTM Mode?
Secondary question: if none of the above worked and I do have to flash the OS, can I flash it myself to default Jellybean? Any idiot-friendly step-by-step guides out there?

Here you are! (I was the one talking to you on Reddit)
Since you can get to fastboot you can just flash the stock image files and you should be fine! The toolkit is in the original dev section but you cannot download the images from it anymore. A few people here have the images though so hopefully someone will pop up with them shortly

No worries! You can use the toolkit without knowing fastboot, I just recommended learning it in case you ever need to flash without it. I believe after you download the toolkit there will be a folder you can place the stock image into then you can use the toolkit to flash the image from that folder. I'm not 100% what folder that is though but I believe the name makes it fairly obvious if you look for it

Unfortunately, I haven't even been able to install the bloody USB driver, so fastboot/adb can't even see the device. I've described by problem here. I think the source issue is what LG did during repairs... the device is named "Full JellyBean on Mako" instead of something like "Nexus 4", so the drivers in that post aren't being recognized by Windows as valid for the device. At least that's my guess.

OK, got it all fixed.
This post was incredibly useful. Once I got the USB drivers installed and fastboot recognizing the device (oddly, adb wasn't able to), it was extremely smooth unlocking the bootloader and flashing the image.
Thanks!

For future reference ADB only works in recovery and when booted into android, never in boot loader. Bit glad you got it working
