Hi My nexus 7 was working fine I had a custom rom (paranoidandroid ) tried to upgrade to the latest release and now stays stuck at jelly bean splash screen

installing frivers through wugz 1.5
nexus root kit uninstalled reinstalled tried to connect in fastboot mode nothing
I used a windows 7 box and an xp box updated usb drivers on both pcs nothing its like the port on the nexcus 7 was broken or something please help!
The only way I see out is if maybe I can connect through linux but not sure how to I do have a laptop running backtrack I could use

Wrong forum for this but:
Sounds like you tried to install on top of the existing ROM without wiping.
Can you get into fastboot? if so open a command prompt from the folder you have fastboot.exe installed and type "fastboot devices". do you see your serial number? If so you're fine! Flash a custom recovery you can easily wipe/reset and wipe dalvik cache and install a new ROM.

I can get into fastboot and it doesnt recognize it ive tried everything different cables etc
also i was upgrading from 1.9.2 to 1.9.5 so a full wipe was not required
My main problem is i cant connect cant list devices

so if you're in fastboot mode and you type "fastboot reboot-bootloader" nothing happens?
I don't see how installing a ROM would cause these problems.

I dont see either I dont get it and I cant get into recovery if i try that it gets stuck at google screen
if i try to boot then I just get stuck at splash
tried different systems no dice

Put your device in fastboot mode. Do not connect it yet.
Run wugz 1.5.2 (that's the latest I think) and press the "Full Driver Installation guide".
Check the instructions to remove your current drivers. Remove them.
connect your device
Reinstall the drivers manually (not via the toolkit). Use the naked drivers from here.
Download the factory image from here and flash it via the toolkit.
root it, flash cwm do whatever you want to do :silly:
profit

Wont respond or recognize it

You need to install the drivers. Do you know how to get into your device manager in windows and install drivers for devices connected? You need to dl th wugz that regunus told you about above. After installing you can tell your computer to search in that folder to install drivers. When you open your device manager do you see anything yellow with a question mark. Once you have the drivers installed correctly then follow this http://forum.xda-developers.com/showthread.php?t=1781250 and you will be golden. Been through this a couple times already

Also when you try to manually install drivers for the devices that are not recognized in the device manager make sure to guide the driver install wizzard in the folder Universal_Naked_Driver_0.7 (or wherever you unzipped your drivers) and NOT in a specific directory like "amd64" or "i386".
If all drivers are succesfully installed, your computer will see the device in fastboot mode and your problems are gone ^_^

You can install the toolkit from here http://forum.xda-developers.com/showthread.php?t=1809195 then use it to install the drivers, then install temp cwm, then reboot into recovery, do a full wipe and try to install 1.95 again. You can use the toolkit to install a rom as well if you download it to your computer. Hope it helps.You always have to wipe cache and dalvic cache when flashing any rom. No wipe means you don't need to do a data/factory reset.

Check the Device Manager in the control panel to make sure all the drivers have been installed correctly. After that we'll see

Regunus tried no avail.
I reformatted my laptop dual boot windows 7 32 bit.
Tried all previous suggestions its not recognized, me and Regunus came to the conclusion that the port can't be bad Cuz it charges yet it does not recognize it.
I just finished installing adb fastboot on ubuntu if I go to terminal and list devices nothing if I connect my Galaxy sIII it shows up so again not being recognized while other devices do.
Current state :
Fastboot start goes to paranoid android jelly bean splash
And hangs
Fastboot recovery stays stuck at Google screen
I have reciept and all to bad I can't return may just post on ebay

Same Issue
I'm having the same problem, was this ever resolved?
Edit: I was having the same problem. Downloaded 'Nexus 7 Toolkit' and ran the 'install driver' option again (option 1). Device was recognized again.

No such thing as no way out. Keep find a way to connect and you're all set. Have you tried force reboot to fastboot and then enter recovery? I have similar problem once with my nexus s and i finally find a way after 10 hours of constant googling

I've tried nexus 7 toolkit
I reboot into fastboot mode and select recovery and it goes to Google and hangs I've tried on different post nothing at all

Bricked nexus 7 please read!

Hi,
I. Have gotten myself into quit a frustrating situation. My nexus 7 was unlocked, rooted and had several different custom roms installed at various times and had never had a problem. But then one time in particular, when trying to flash a rom (which I can't even remember which one it was,) after the rom had "successfully" been flashed, it rebooted to the splash screen, which it stayed at for a very long time; before just turning into a series of flashing vertical lines that never end. I can use the power+vol- method to get to fastboot, but not recovery; it would appear that my recovery has been wiped as I get the same google splash screen loop as when I try to boot. My problem is that nothing I do allows me to successfully connect the device to my pc (w7, 32bit.)
I have uninstalled any conflicting drivers, un/re-installed the proper drivers from like 7 different guides, I have also tried two different nexus root toolkits. I even tried to use a Linux machine to no avail. I have switched USB cables, everything I have tried has not worked. This is by no means my first foray into android devices, I even freshly installed my android SDK and still my computer just fails to recognize the nexus 7 in fastboot mode.
Any tips or advice would be a godsend. Thanks.

This sounds like a issue a few people have been having.. As far as i know as of a week ago there is no solution . You need to flash the boot-loader it sounds like. There is a thread about this. Search for NV FLASH .. OR APX MODE. Sorry for being lazy and not looking for the thread for you..
They may have some things in that thread that you have not tried.

Turn your Nexus off and plug it into your computer. Does your Nexus start charging? A completely bricked Nexus wouldn't charge. If it starts charging, then try turning it on into Fastboot mode.
Sorry, I'm no dev. Just a random thought to try. But if your Nexus can charge you shouldn't be fully bricked, hopefully. At least this is what I think.

When you say your computer fails to recognise the device...
If you open your device manager in Windows and then plug in the nexus 7 in fastboot mode, what happens? Does it show up in the device manager in any category? Even with a yellow exclamation mark or as unknown device?

My bro bricked his N7
He was rooted and unlocked, flashed a rom now it bootloops on the logo. Now when doing adb devices, it doesnt detect the device when in bootloader, went to device manager and shows problem with driver. Tried other drivers but says its up to date. Thing is I just upgared his friends N7 with the same drivers so I know thats not a problem.
It wont go into recovery either. Now when it is bootlooping, the decive is recognised when doing adb devices. So can I flash a factory image when it is bootlooping or does it have to be in fastboot?

TRY THIS
from powered down,
hold VOL- and POWER for ten seconds,. then let go of POWER and still hold down VOL-

Just goes to bootloader?
Edit seems to be working now even though when doing adb devices in fastboot it doesnt list the device id

In fatboot mode you don't have adb access - down load a recovery image and name recovery.img
Hold shift and right click in the folder recovery.img is in
Choose open command here, in cmd type
fastboot devices
If you see your serial number proceed
fastboot flash recovery recovery.img
When finished reboot to recovery and flash rom of choice
ps, you have had to either change your path in enviromental variables to include platform-tools from the sdk or have both fastboot.exe and recovery.img in the same folder that cmd is pointed to

[Q] USB and recovery problems after OTA upgrade to 4.3

I took the OTA to 4.3 on my Nexus 7. It was previously unlocked and rooted, but had no kernels, etc changed. After the update ran, I lost root as expected, however, in trying to get it back, I've discovered I'm having a couple of other issues.
First, the device is no longer working properly via USB on my PCs. On both my Win 7 and Win 8 PCs, the device won't properly connect to where I can browse files or anything else. On the Win 8 computer, I see a Nexus 7 device in Device manager, but drivers won't install. I downloaded the drivers from the Asus site, but trying to manually install them doesn't work on the Win 7 machine, and on the Win 8 machine, they install but don't seem to be working with the Nexus 7 as it still shows a problem in Device Manager.
The tablet also will not boot into recovery mode. I can power it up into fastboot mode, but if I select "Recovery Mode" and hit the power button, I just got the Android with the red triangle for a few minutes before it boots back into the OS. After doing some searching, I saw where you might need to have it plugged into a PC to get it to go into recovery, but that doesn't work, either (might be tied to the USB problem).
Ideas?

Did you turn on developer options, and USB debugging? Have you tried USB connection type PTP instead of MTP?
If you have the stock recovery, the red triangle and Android are normal. You can bring up a blue options menu by pressing the power and volume up buttons from the red triangle Android.

Try another driver source. Wugfresh's installation is a lot tougher than Skipsoft's, but try the other guy 's system.

I was using the stock drivers off the Asus page. I'll look around for the two you mention. I assume they're posted on here somewhere.

And about the recovery just try flashing another recovery from fastboot

Without USB access? That's my dilemma.

OK, I'm getting closer. I got TWRP installed and rerooted it. I had to do the "Revoke USB debugging authorizations" on the Dev Options screen. Then it would work via ADB.
Still not browsing files yet on my desktop, but at least I know I'm talking to it. So now I'll play with the driver installation a bit.
EDIT: Well, drivers reinstalled for about the 4th time, and it's still not allowing me to browse files from my desktop. Galaxy S4 works fine as soon as I plug it in, even if I also uninstall it's drivers. Ideas? I obviously have it working over USB because I can give it commands and reboot it via the PC.

OK, try this one. Plug in your tablet to pc, go to hardware manager, find your Android Device then choose Uninstall (choose Remove all drivers for this device), unplug and plug in your tablet again. Your Windows should discover few new devices (mine has discovered three) and download drivers for them then you should see Android ADB Interface in Android Devices and Nexus 7 in Mobile Devices.
--edit--
I've solved my issue

After you plug your nexus in have you unlocked the screen to see if it is asking you to authorize the tablet?
What other steps have you taken? Have you installed proper drivers? Have you manually chosen to update drivers with the sdk drivers if in device manager is showing the nexus? Have you tried the drivers from Asus?

I personally did all of those things. After having the Nexus "forget" all the other PC authorizations on the dev screen, I finally got it to accept ADB commands, just not to properly install drivers that would allow me to browse files like it had done on 4.2.

[Q] Boot Loop - what happened?

I was on Google+ and I checked out a youtube video, it was about a 3d printed engine. After watching the video I shut the screen off and I went to bed. When I woke up in the morning my tablet was displaying the Google logo and then restarting. What did I do?? The tablet was fully charged and wasn't plugged into anything. I could understand if I was tinkering with it but I hadn't done a thing. Now I don't know what the heck to do. I've tried Wug but I can't seem to get the ADB drivers to be recognized on my laptop, Windows 7 64bit. I'm at a loss as to what I should do next. Any help would be appreciated.
It was running 4.4.2 (KOT49H) for about a week.
**I should clarify the drivers thing. Windows says everything is installed and running correctly (Android Composite ADB Interface) but Wug is saying that ADB cannot be found.
**and for whatever reason the word Composite is throwing me off with the driver thing because nowhere in Wug's tutorial is that label for the driver but my laptop only seems to find that driver.

Leave it for 1 day to charge and then try to turn it on without unplugging till boot finish...let us know what happened

Go into recovery mode and wipe cache and reboot and see if that fixes it.

I don't have the ability to go into recovery mode. All that happens is the Google logo comes up and then reboots. I can get into the fastboot screen but nothing else. I can power it off and it'll charge but reboots before it can go into recovery.

are you sure you have the correct drivers installed? I'm on Windows 7 64-bit and it works just fine.
You might want to go into device manager and remove the device completely from Windows 7 and then try reinstalling the device drivers.
Worse comes to worse, get the Nexus 7 toolkit from Skipsoft.net. It contains all the correct drivers. That's what I use.
Try that. If you can get into fastboot mode, then you will be able to reflash everything back as long as you had USB debugging enabled. You can choose to keep data or do a complete wipe of everything with the N7 toolkit.
I never used wug as I've always had great results with the N7 toolkit.

I ran into a similar situation go to wig fresh put your device into fastboot. Then click softbrick reboot it will wipe your device but it will fix it make sure you select the same software you want to install. K

After deleting all the drivers I knew were Android I also deleted all the generic usb drivers as well, which I didn't think to do earlier, and then wug could see the correct ADB drivers.
I tried Skipsoft last night and it is far more feature rich but I had the same results. Still bootlooping. On the plus side I was able to re-lock the bootloader, which I couldn't do in wug from the fastboot screen, so I can have it covered under warranty if nothing else.

[Q] Wiped my Nexus4 OS What do I do?

Help!! I wiped out my os on my Nexus trying to load a ROM. I can't figure out what to do. If I boot the phone it stays on a screen that says google. Everything I have found so far says to check USB debugging but I can't get to that because the phone doesn't fully boot. Also my computer is not showing my phone in windows explorer but does show a nexus device in devices and printer & device manager. As far as I can figure I have to somehow get the computer to communicate w/the phone and then load an operating system but can't seem to figure out how to do this. I can get to TWRP but find nothing there to help. What ca I do?

You need to use adb to push or side load a rom to your device while you're booted into recovery

Thanks. Thats what I am thinking but my device won't show in windows explorer, so I don't see away to communicate w/it. I have tried installing the device drivers but all I have now is it showing up in Device Manager as Google Nexus BootLoader Interface.Right now I am working with ADB and Fastboot and I think I have it working but I am still stuck on the drivers and the device showing up.

download WugFresh toolkit, download factory image from google, download universal ADB drivers.
enter bootloader, you should see an android with chest open, stay in bootloader and connect your phone to PC, flash ROM through Nexus 4 Tool kit.
you dont need usb debugging in bootloader

Google 15 second adb install xda. Has adb and the usb drivers. Try that. Factory image is going to wipe your device. By dirty flashing the rom you're on you'll save your data.

Thanks Mashed_Potatoes. I tried Wug & Skipsoft toolkits but did not do it in bootloader mode. Hope I remember that for the next time! Still having trouble with the drivers and computer seeing the phone. In device manager should it be android device--Google Nexus ADB Interface? I just don't remember that and the phone doesn't show up in explorer, but it's listed under devices and printers. I hope I can get it. Wug toolkit gave me an error trying to install drivers. Thanks for the help

I didn't understand you, you managed to flash the ROM but not in bootloader? It won'tsay Google Nexus ADB Interface, i don't remember precisely i've done it a long time ago!

I managed to re-install 4.4.4 with wug toolkit in bootloader. I got my OS back but have not been able to get the drivers sorted out (yet) so the Nexus isn't communicating w/the computer fully but I can still flash roms and install apk's w/wug also.

Try a factory reset and reinstall the drivers in PC
