Stuck on Google and unlock icon - Nexus 7 Q&A, Help & Troubleshooting

Since upgrading to Windows 8 the toolkit for android and pretty much the drivers are impossible to get working.
It seems that the device has nothing on it, zip, zero. No matter how I try to recover it what ROM it tried to install it didn't work and when I try to access anything via command prompt it can not find the device.
I look at the devices on system manager and there is one listed as unknown device but I do have android phone listed as a device.
It plugs in, makes a sound knowing there is something but its unknown. Tried using the Samsung drivers, no luck there.
I need to do a complete reboot, get the original folders back on but don't know how to get it to recognise and get things going again.

You need to disable driver signing in windows 8 to be able to install drivers for the Nexus.

Done this already, for some strange reason the device listed in Device manager now knows its a adb interface but still listed as a unknown device.
Try getting to look at the Samsung drivers but still no luck.
When you go into the device properties it states the following;-
Windows has stopped this device because it has reported problems. (Code 43)

Windows 8 doesn't seem to work very well with adb/fastboot etc...
Do you have access to another computer that has Windows 7 (or XP, Linux?)?

Thanks for you help guys so far.
I do have a Vista 32bit laptop that I can use. Going to install the Toolkit, drivers etc on there and see how far it goes.

I've read where people who are using Win8 and fastboot flashing .img files to get back to stock, it stops/locks up in varying spots...after three hours of messing with it they try another OS (Win7, Linux) and it works within minutes.
Hopefully, Vista works...and I'm sorry you have to resort to Vista!

Well I seen to be getting somewhere but still with strange issues in Device Manager.
It shows Android device with the following devices below.
- Android Composite ADB Interface (yellow exclamation mark)
- Google Nexus 7 ADB Interface (yellow exclamation mark)
- Google Nexus 7 ADB Interface (yellow exclamation mark)
- Google Nexus 7 ADB Interface (yellow exclamation mark)
- Google Nexus 7 ADB Interface (yellow exclamation mark)
- Google Nexus 7 ADB Interface (working properly)
- Google Nexus 7 BootLoader Interface (yellow exclamation mark)
Further down I have Portable Devices with MTP Device listed (yellow exclamation mark).
I have Google Nexus Toolkit installed.

Strange. Did you install the USB drivers? Maybe download them from Asus, extract them to your Desktop, right click on your N7 in Device Manager and unistall the drivers for your device, then connect your N7 and browse to the location of the downloaded USB drivers....?

Okay following God knows how many windows updates, following restart I can see that the MTP device is now showing as working properly.
When running the toolkit (version 3.2) it shows the device number at the top under ADB mode but not under Fastboot mode.

Remind me which USB drivers?

Okay, puzzling but it appears to be getting somewhere.
In device manager there is one instance of Google Nexus 7 ADB Interface under Android Device and MTP Device under Portable Devices even though it seems to reinstall the same instance of MTP device every 1 minute or so.
I am installing the Samsung drivers however, the same as before when it comes to the Toolkit. The ADB mode list of devices shows correctly, nothing underneath fastboot mode.
What would be the next stage?

I would boot into fastboot, change directory to your Android SDK - Platform Tools directory, and if you type: fastboot devices
does anything show up?
Well, I would reflash stock images completely. Hopefully you have a backup of whatever is/was on your internal sd card because doing this will erase it.
You can get the image from here (note, I am assuming you have the N7 Wifi Only): https://developers.google.com/android/nexus/images#nakasi
Then, you can revert to stock by following this post: http://rootzwiki.com/topic/28544-guide-nexus-7-bootloadersrecoveriesrootback-to-stock/#entry764332
NOTE: Step 10 the file name will be different than shown.

Ok so I have managed to get into the ClockworkMod recovery v6.0.1.9, going with the 'install zip from sideload', used the command adb sideload nakasi-jop40c-factory-6aabb391.tar.
The screen on nexus says:
Restarting adbd...
Finding update package...
E: Cant open /tmp/update.zip
(bad)
Installation aborted.
Sorry about this I am a complete amateur when it comes to this stuff, thanks for the help so far.

UPDATE: - I used the CLEANROM 2.5 zip file and it has now gone back to its original state, YES, thank you so much.
This may have happened when I started to use Paranoid Android, they brought out a beta 5 version, which originally worked but I can't see to get it updated via the 'update recovery' step.

Steps done, back to stock which is great, thanks a lot.

Oh man just when I thought my problems were finished.
One thing I forgot to do was run the superuser zip file to give permissions on the clockworkmod recovery. Even trying to do something with Rom Manager within jellybean itself but it says I need permissions.
How can I reverse back and get the superuser.zip from working? At the moment I can not access recovery, tried using command prompts and Rom Manager but to no avail.

You can boot back into fastboot, and download the latest TWRP Recovery from here: http://teamw.in/project/twrp2/103
They even give you instructions on the command to run type in: fastboot flash recovery <name of recovery file>
Put the .img file in your Android SDK - Platform Tools folder as well.
Type in the flash recovery command, then reboot to recovery.
From there, you can flash the Superuser.zip (I assume you have it?). If not, here it is: http://download.chainfire.eu/282/SuperSU/CWM-SuperSU-v0.98.zip
You'll also want to make sure that the following files are deleted/removed:
/system/etc/install-recovery.sh
/system/recovery-from-boot.p
The reason being is that if they are there, it will reload the stock Android recovery at reboot, which will remove TWRP or CWM if you have flashed those. I would just rename them by putting a .bak on the end of the file names. But to do this, you'll need root first. You may have to: fastboot flash recovery, flash SuperSU zip, reboot, browse to those two locations to verify if those files exist/rename them, fastboot flash recovery again...reboot, and recovery may stick. When I went back to stock and fastboot flashed TWRP, I checked for those files and they weren't there, and recovery stuck just fine.
You're learning the manual way, congratulations! Not too bad is it?!

Clockwork Recovery is Installed, Won't Load, missing recovery partition.

I'm putting this in General because this is my first time I've actually posted on XDA and I hope someone will move it to wherever it needs to be.
I've rooted my Nexus S a long time back when it was new, originally had some trouble with fastboot hanging on "waiting for device" I want to say trying PDANet fixed my problem then. I'm not foreign to the flashing/rooting process. And I know this is a long post but If you can please read it all it would be appreciated.
My Story:
>ICS was released and while Google said Nexus S would get an official update I saw some on XDA that were promising ports.
>I downloaded We Scream for Ice Cream Beta 9 and installed through Rom Manager
>About a month later I'm fed up with all the force closes and missing features the thread didn't inform me on and went to find another ICS Port.
>Downloaded and about to install through Rom Manager I'm informed that I need Clockwork (strange because I already have it) so within Rom Manager I flashed a new one.
>Install via SD Card and my phone reboots and then instead of loading recovery and doing its stuff I wait at the Bootloader screen. I try entering recovery myself and my phone restarts and again I'm at the bootloader screen.
>At the very bottom of the screen in gray lettering it says Fastboot FAILEDcommand
(As of now it displays the Google Logo with the unlock icon and hangs)
>At this point I decide I' going to flash over clockworkmod myself via adb. This should be the magic formula: via addictive tips (new user, can't include hyperlinks)
Code:
adb push c:\flash_image /sdcard/
adb push c:\recovery.img /sdcard/
adb shell
su
mount -o remount, rw /system
cp /sdcard/flash_image /system/bin
cd /system/bin
chmod 777 flash_image
flash_image recovery /sdcard/recovery.img
>Adb gives me an error similar to won't link after the mount/remount command. Also trying to cp the flash image to bin fails to work.
>I boot my phone, open Total Commander and try to copy the flash image myself to the bin folder in my root and it fails
(As of now I get error: device not found)
Then i think alright, maybe it's my drivers. I tried several different drivers from different tutorials because perhaps they are different in some slight way. >Whenever I try a new driver I can pick "adb Composite" "bootloader" or vanilla "adb interface".
>My device appears as "Android Phone" as the first entry in the Device Manager and the icon is a monitor with a small PCB chip in the corner.
>When the divers are completely uninstalled it appears in Other Devices with a yellow exclamation point.
>My understanding is that while it will automatiaclly grab the driver for USB mode, I have to force it to install the bootloader driver for when my phone is in the bootloader screen.
>And USB Debugging has been checked for everything I've done.
>Now i try to use PDANet, first I uninstall the drivers and install PDANet. Message appears saying there is already an Android Driver installed, I choose reinstall, select Samsung, pop says are you sure you want this driver, publisher cannot be confirmed? I click yes, I beleive that happens twice, it installs and then runs. It installed the vanilla "adb interface" driver.
(This is where I'm at now, the Fastboot FAILEDcommand is also gone.)
So now I'm like well there's fastboot, let me see if it recognizes it.
>Fastboot devices: nothing appears
>fastboot flash recovery recovery.img : it hangs on waiting for device.
>Same goes for other commands like OEM unlock.
All the while ROm Manager insists I have clockwork recovery verison 5.x - only it wont load and none of my PC options are recognizing the phone. So I can't flash over a different recovery image, and there;s nothing under alternate recovery in Rom Manager.
And the strangest of them all which may be Rom Manager's problem is that Super User FCs as soon as I try running it. Rom Manager states Super User gives it power at the end of the clockwork recovery flash, however, still says it's successful.
Before this entire thing my phone tried to OTA update to 2.6.7 for Google Wallet and where it would normally respond I got the Android Guy with a box and a yellow exclamation. This is also what I got when I first had some problems rooting months back before I flashed over images and roms. I figured it wouldn't update because it needed the stock recovery image and wasn't compatible updating with clockwork mod (however i think my phone has updated before with this method.)
I wouldn't mind rolling back to my stock deodexed version of Gingerbread at this point because the ROM I have now for ICS NFC and Bluetooth wont work among a slew of problems. And NFC was the major update in 2.6.7 in regards of tap to share and Wallet.
So I either need ADB and Fastboot to recognize my device to try reflashing clockwork and an Entirely new ROM remotely (if that's possible) or get clockwork mod on my phone to open.
More Details
Also when I load the recovery image and it loops back into the bootloader I get the message up top saying I don't have a boot image or recovery image. yet my phone still boots fine.
I really want my phone to work %100 again, can anyone help me?
I didn't read all you wrote, but if you're having trouble getting adb or fastbook to work correctly just use ROM Manager. Even if it says you have it installed, do it a few times. You can also go into settings and check off the format or erase recovery option before flashing.
It will eventually work. Just keep trying it.
Thanks
I know I've read things where flashing several times gets it to work. But I'm wondering if because SuperUser force closes without opening it's unable to give RomManager the permissions needed to complete the flash.
I've tried a few times ever once in a while. Still waiting, but adb will recognize my phone on my guest login but still no fastboot.
What rom you on? Have you tried going into app manager and then clearing data for superuser? Try that and then reflash the recovery a few times from rom manager.
If you're using CM9 alpha 11 or any of the builds by Koush, and superuser FC's from fresh flash. Clear the data, use root explorer or another app that has root access (it will prompt you for root access even if superuser UI won't open) then you can go into /system/app/ and delete or rename superuser.apk.
Once that is done, get the latest one from the market. Soon as it installs, clear the old data from the previous one by using app manager again. Then your superuser app should be working normally.
What's your phone model? (I guess it's I9020T)
When you boot into bootloader, does the fastboot devices command see the device properly?
You should use fastboot to flash your recovery. You probably have driver issues. Check the rooting guide at nexusshacks.com.
Sent from my Nexus S using XDA App
Fixed
Thanks to everyone and heir suggestions.
Eventually I downloaded another set of Fastboot and ADB registered with my phone and I was able to flash a new ClockworkRecoveryMod.
My only explanation is that the two tools where in the same folder this time - that was the only part that was different.
However ROM manager will still tell me I do not have Clockwork on my phone and when it 'flashed' it over it actually breaks my recovery partition all over again.
Thank god for ADB and Fastboot.

Nexus 7 won't show up in adb devices, what should I do?

Earlier today I flashed Kaos Droid to try it out, but it put my Nexus in a state where it would not go past the screen that says Google and has the lock at the bottom. Since I have TWRP, Reboot to recovery from boot loader didn't work. I tried fixing the problem in not Windows and Ubuntu, but Windows kept on ending up as unknown device and no matter what drivers I tried to make it use it would not take, and in Linux it didn't show up in adb devices. I got lucky and it rebooted into TWRP after my fifth try of selecting recovery from the boot loader. I restored from backup, but I don't want this to happen again, if that ever happens. What should I do to get it in adb devices? Thanks.

How could I turn that on from bootloader? It was and is on before flashing the ROM and after restore.
Should have been able to run fastboot commands, either to try to reboot into the existing recovery, reboot into a recovery image, or flash a new recovery.

Have a look at the Device Manager in Windows with your tablet plugged in. If there's that yellow triangle, just right click and choose update driver. Then you just browse and point Windows to where you have your N7 drivers.

That's the thing, I pointed it to official N7 drivers, Google USB Drivers, SuperOneClick drivers, and a bunch of other ones. It would never take--saying either that the best drivers are already installed (even though none were installed) or no suitable drivers exist in that directory.
I'm having a similar issue here, except I can get to the "X" boot animation.

Sometimes it seems to me that, even though USB debugging is "on", it really isn't.
Several times I have had to un-check and re-check "USB debugging" before adb would recognize the device.
Just my experience. Your milage may vary.
i'm in the same boat !

Any ?
Are you on 4.2.2? There now should be a security dialog upon executing an ADB command on the device, it will prompt you to allow the command to be executed.
If tou aren't on 4.2.2 - then it seems to be either a driver or a ROM issue
Yes I'm on 4.2.
I had this problem too and reinstalling the SDK tools fixed it for me for some reason.

Maybe try using wugfresh toolkit. I've seen people say they couldn't use adb or fastboot but the toolkit worked. Doesn't really make sense to me since the toolkit just sends the commands for you but hey, worth a shot. It will walk you through uninstalling current drivers and doing a fresh driver install also.

I use this kit. Remove all drivers. Then install the driver again. The drivers has been install in fastboot mode and recovery mode. The nexcus is recognized in these mode by the wugfresh toolkit.
Unfortunately in normal mode, when i active usb debug mode, i get a unkown device on windows 7 32 with any possibility to update the drivers.
I get error unkow device, device is stop error 43
Cable is stock and also try another one.
I get same message error on another computer with windows 8
I confirm that my usb issue is solved.
After a factory reset, i reinstall the last release Usb ROM and USB comes back to life on my nexus.
The nexus is no more recognized as unkown device by my computer and i can install the adb driver.
During this story, i try also to get acces via wifi but was unable to connect even with adb over wifi enable on the nexus.
That why Timur recommands me to made a full factory reset.
My problem seems to be due to corrupt data that block every connections between the computer and the nexus (adb wifi and usb) based on last 4.2.2 new safety features.
So far i recommand full wipe between two rom install to avoid such trouble.
Thank a lot to timur for his support during the week end.
If your nexus is rooted, go in recovery mode and install a new rom from zip.
How to ?
Download rom of your choice via wifi
You can download a rom directly from your nexus to sd.
Check here for download (example)
http://mehrvarz.github.com/nexus-7-usbrom/
Download Google applications on your nexus via wifi
Download from here : http://donandroid.com/gapps
Before installing new rom make a save using titanium backup.
https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup&hl=fr
Save all your application and data in batch mode.
Create titanium.zip on your nexus 7 sd.
Then from recovery mode make a full wipe but without erasing sd data.
Follow these instructions :
Unless you format the system partition and system caches, you aint wiped nothing, there is only one way to carry out a proper full wipe, and thats the full wipe the correct way.
1. Boot into recovery
2. Wipe the cache partition
3. Go to advanced and wipe dalvik and batt stats.
4. Go back to mounts and storage and format system, then data, then cache.
5. Go back and install the rom zip file from the sd card.
6. Reboot.
No need to wipe data/factory reset, the contents of your internal and external sd cards are untouched.
From Recovery mode
- install titanium.zip.
- install gapps.zip
Reboot
Go to titanium backup and recover all your data.
Et voila...

So I messed up my Nexus somehow. I was trying to install MIUI coming from Carbon ROM but something went wrong as it got stuck on the miui logo. So I rebooted to TWRP and restored my backup. So then I tried to install PA and then it just got stuck on the google logo. So i restored my backup again and tried again to no avail. Then after that I couldn't restore my backup ( I keep getting FAILED as soon as the data restore starts). I can boot to Recovery but I dunno what to do. I tried sideloading but that's not working. I tried the toolkit but everytime it tries to download the factory image it says 404. The phone charges and whatnot but I don't know what to do. I only have the PA rom on my phone and reinstalling it doesn't do anything. The only weird thing is that when I try to install the PA gapps I get a FAILED message. Any help would be appreciated

Have you tried to install another rom on your nexus?
you can put it on with adb push command from recovery though a pc, and then wipe everything and try to install it.
Or you can download stock 4.2.2 rom here: http://forum.xda-developers.com/showthread.php?t=2147281

you must enter into recovery, connect your phone to your pc with usb cable and then you should be able to see your device,
try
Code:
adb devices
on CMD and it can see your phone type
Code:
adb push **your-rom-from-computer** /sdcard/
then just install it from the recovery
When you say recovery do you mean the main menu? I'm using TWRP and when I'm on the main menu my PC doesnt read the device

Ok, wait. I need some clarification. I'm going to try to be as simple as possible, to make sure we are on the same page. When you say your PC doesn't read the device, do you mean through adb or on Windows Explorer?
If you mean through Windows Explorer, then that is not where you need to be. You must get adb working as a bridge to your device. Use this sticky guide to get it set up. I would recommend reading that guide top to bottom anyway, it's extremely informative and new-user friendly. Anyway, the info you need is in the 'Setting up ADB for our device:' section.
If you have adb installed, you need to check to see if it recognizes your device. Do this by opening up cmd and navigating to the folder that adb.exe is located. After that, use 'adb devices' to see if adb recognizes your device. If so, move to the next paragraph. If not, your drivers aren't set up properly for recovery mode. Go into Device Manager on your computer and find your device (under something like 'Other devices', or 'Android device'). If you find it, then get these drivers and install them for the device. Do this by right-clicking, and selecting 'Update Driver Software...', 'Browse my computer for driver software', and browse to that folder. I may have missed a few steps on installing the drivers, it's been a while. If so, just search on how to do it, or post back here. I'm sure I can walk through it and get a more precise guide.
Assuming you have adb installed and it recognizes your device, you need to open up cmd and navigate to the folder that adb.exe is located. Then, use the adb push command as outlined above.
Download stock images from Google's website and flash it via fastboot. If you don't know how to do it then use a toolkit like WuguFresh to do it for you.

You can also use the toolkit for pushing a ROM in your SDcard, or backup your SD in your pc.

The PC reads the device as it detects it but when I type in adb devices it doesnt show up. It only ever shows up when I enter the sideload menu in TWRP

Download stock images from Google's website and flash it via fastboot. If you don't know how to do it then use a toolkit like WuguFresh to do it for you.

[Q] TWRP no OS installed, can't connect to PC

Hello,
I just got the OTA message for 4.4 and tried to install it but I got a bootloop. After clearing the cache and performing a factory reset in TWRP (which got installed through Nexus Toolkit) it still didn't work. Someone told me to perform a complete format through TWRP which I did (hindsight, I know) and now TWRP says I have no OS installed, adb won't see my device (I have the drivers installed) and when I go into the bootloader (which says FASTBOOT MODE) fastboot still won't recognize the device (nothing shows up on my PC either but that can be normal).
I'm at my wit's end here, is there anyone who can help me?
You need to realize that if you want to install OTA, you need to use stock recovery. Even though it is possible to flash through TWRP, it can still run into problems. Especially when you made root modifications to your device.
You don't have to do a full wipe for everything. There is a method to flash factory firmware without wiping data (link in my signature). After that if it still don't boot due to existing data, boot into a custom recovery and do a factory reset without wiping the internal storage.
But since you have custom recovery already, just go into the Development section, find a stock KitKat rom, download it and sideload it using TWRP (which is enabled it in the Advance menu).

Yes I've tried that but I don't know how to sideload it. adb doesn't see my device, fastboot doesn't either and windows doesn't recognize the device (although I have the adb naked drivers installed).

If it is connected adb should see your device while in TWRP. Fastboot only work in fastboot mode (bootloader screen), not in recoveries. If you have the UND installed then they both should work, if not it wasn't installed correctly. If you are using Windows 8 you need to disable driver signature before you can install UND (search google for that).
You could also make a bootable Ubuntu flashdrive, and use the ADB/Fastboot for Ubuntu link in my signature to install them.

I tried both. ADB devices gives me an empty line and fastboot devices (when in bootloader screen) gives me nothing at all. I've tested 2 different computers (both windows 7 x64) and it still won't detect it. When in TWRP windows tries to detect my device but it says "Unknown Device" and gives the yellow triangle.

You might have to point the drivers to your phone. If you go into device manager, see if your Nexus 4 has an error. If it does, right click it, and then update the driver. Do a manual install, and point it to the .ini file for the driver

Fix your drivers, uninstall them and select the checkbox to delete the driver files, search Google on how to disable driver signature and try reinstalling the driver again.
or
Make a bootable Ubuntu flashdrive, and use the ADB/Fastboot for Ubuntu link in my signature to install them.

I've tried 3 different computers, 2 different OSes and 3 different cables. Nothing seems to work. I'm really starting to panic now.

Just to clarify, see attachment for the correct name of the device if UND is installed correctly.
If you tried it with Ubuntu, make sure you do the 1st step from here also:
http://bernaerts.dyndns.org/linux/74-ubuntu/245-ubuntu-precise-install-android-sdk
Same here
i installed the ota update normally with twrp installed everything went fine but im kind of disappointed in this update:/

These are my findings:
Ubuntu:
- Bootloader (fastboot)
-- running lsusb in Ubuntu shows no device
- TWRP (adb)
-- running lsusb shows no device
Windows 7 (3 different computers)
- Bootloader (fastboot)
-- Windows gives the following popup, no device listed in Device Manager
- TWRP (adb)
-- Windows gives the same popup as on fastboot and this appears in the Device Manager:

Is file transfering working atleast? If it is, then it's a software problem. If it isn't, then it could be a hardware problem, you can try replacing the USB charging board for the phone. Also some roms with corrupt files can cause this issues, so try a different roms if you haven't.
File transfer used to work but atm I'm unable to even connect it to a computer so I can't actually transfer any files. If I could I would flash a rom but no files = no flashing.

Get one of these: http://www.ebay.com/sch/i.html?_nkw=nexus+4+usb+charging+port+replacement&_sacat=0
If it don't work, then use the phone as a door stopper.
hey guys, I'm having the same problem here but with a Nexus 5 now.
Its been over a month and I've kind of gave up over the situation.
I couldn't resist to write a comment on the thread, since it appears to be the same problem as mine.
long story short, I decided to order an USB charging port to replace the one on the phone (as my last attempt).
Otherwise I will consider using the device as a door stopper.

[Q] I Think i'm so f....., only CWM 5.5.0.4 and NO OS.

Only Have in the Phone the CWM R 5.5.0.4 nothing more, i try to install the drivers in win 7 64 and allways fail :/ how i can solve this, i'm so nervous OMG
Relax, we got you.
Driver installation for Windows is not straight forward. Plug in your phone, then open device manager. You will see an unrecognized device there. Right click it, select settings. Click 'Update driver', then choose the 'From this computer' option. Select the driver folder you downloaded. This should work. If it doesnt, click on the option 'Chose from list of producers', select 'Android' or simply all devices, search for OPPO and select the appropiate driver (Android ADB interface).
This should install the driver correctly. After that, get ADB and fastboot up and running: http://forum.xda-developers.com/showthread.php?t=2588979
Install a current recovery via fastboot. Search the forum for how to do this in detail. The quick version is put your phone into fastboot mode, plug into PC, start fastboot and type 'fastboot flash recovery recovery.img'.
Then push a current ROM to your phone via ADB. Again, search the forum on how to do this. Do a full wipe in the recovery and install a new ROM.
Please report back if this worked so others with the same problem can use this in the future.

The only thing i need to know was what step i need make to detect the Oppo drivers, you say " click on the option 'Chose from list of producers', select 'Android' or simply all devices, search for OPPO and select the appropiate driver (Android ADB interface)." after that problem solved because i do this kind of things many times before in other phones and its easy.
When drivers are installed successfully just need to go to recovery "power + Vol. Down" and after write in the command window ( adb push "name of the rom.zip" /sdcard/ ) and he start copying the rom to the SD card, after that just install in the recovery choosing the rom in the root of the sdcard, and thats it! Easy :good:
