I have a nexus 10 and was running 4.3 when I downloaded Wug's Nexus Root Toolkit v1.7.2. I loaded drivers using driver solution #2 (solution #1 didn't work for some reason). I followed all instructions to unlock and root w/ custom recovery. I got an error message from the superuser app about an SU binary missing. I researched and found a file to flash to fix this. But the device isn't working properly. It freezes and reboots after 3-4 actions. Any actions cause the problem, whether it's going into settings and changing something, moving a widget, or trying to open an app. I can't even get the file onto the device to flash. So I flash stock and unroot and re-lock (all using Wug). The device has the same problem as before... I can't do more than 3-4 things before it freezes and reboots. I never had this problem before I unlocked and rooted. Has anyone run into this? I've searched for a while and can't seem to find a similar thread, and I apologize if there is was somewhere that I couldn't find. I just want my tablet back.

Hello there everyone.
First off, I know this might seem like a subject that's already been covered. Trust me, I've spent the last few days going through every thread I could find on here trying everything out as well as other threads on tips on the net. So I'm posting this because I've tried everything and run out of troubleshooting methods to have a go with. The experts here may relish the challenge of solving this one. Or tear their hair out just like I'm doing. Hence my username. I'm worn out after countless hours of doing this.
Background:
I had a rooted Nexus 7 with superuser and TWRP. Jellybean 4.2.1 update would never work, always got an assert failed or some other error when it tried to do so. I then decided to go back to a previous backup in case something had gone wrong since in order to get on with installing the update.
Previous backup loaded fine. Unfortunately WiFi was not working and just kept on searching forever. After lots of googling and trying all the fixes with my router and so on which failed to solve anything, took the advice of going back to a factory reinstall.
Reinstalled, booted up, selected language on Google Welcome Screen then onto Wifi screen. Stuck on seaching forever. More googling and took advice. Decided to do Nexus Root Toolkit's flash stock+unroot to get back to clean state. After install there's an issue that just won't go away and that is:
Problem:
Google Nexus 7 (Wifi model) won't go past Google screen (this is not the coloured logo, just the word "Google" in white).
Associated problems:
Going into recovery just shows the same screen or sometimes an android lying on its back with a red triangle.. So no stock recovery available. Using fastboot to lock and unlock the bootoader as a recommended fix has no apparent effect with the result just being the same Google screen (padlock icon unolocked or locked depending upon locking status) even after a long wait.
Flash stock+Unroot in Nexus Root Toolkit has the same result. I left the thing on for a long time each time after a factory install because of advice saying to wait and still the same screen all that time. Longest time was 6 hours left on due to frustration and waiting to see if anything at all would happen. It didn't.
I can't access ADB in bootloader. I can only access ADB when the device is in TWRP or CWM menus. (In other words Nexus Root Toolkit complains it can't connect when I'm in the bootloader for example if I want to do any operation that requires ADB, but doesn't complain when in in those two recovery menus). Nexus Toolkit will quite happily do the Flash stock+ unroot and get to the screen where it says wait a while for device to reboot and you can press any key to exit.
I have wiped system, cache, boot, recovery, userdata using both fastboot and JROM Flasher. I can install TWRP or CWD using the Nexus Toolkit and wipe stuff using those but still no joy. I have gone through every permutation many times step by step. I have even used different Jellybean factory images from 4.1.0 to 4.2.1 as well as past backups with the same result each time.
Have used soft bricked and device is on options in Roolkit. No joy.
I have also disconnected the battery as part of the troubleshooting process.
Basically, nothing I can do using the information I've been able to get hold of can get past that screen.
Other quirks:
I have also noticed when installing a factory image a message comes up:
writing bootloader FAILED (remote: (invalid state))
It continues with the rest of the installation however as normal.
Also PdaNet comes up with the message:
Wrong WinUSB Pipes found
If I try Connect Internet (USB) option.
I have downloaded Nexus 7 tablet USB driver revision R06 and tried to use them but my PC will only recongise the device as an MTP device with failed driver install when the tablet is in that endless Google screen.
With the install of the Naked Universal Driver it only recognises the device in the Device Manager as Google Nexus 7 Bootloader Interface.
Driver tests in Nexus Root Toolkit fail. It advises enabling USB debugging as one of the fixes which of course I cannot do as I can't boot up to reach those options.
From this I surmise there is some problem with the drivers. I have tried on two different PCs as well.
Software I have used in all my efforts: Nexus Root Toolkit 1.6.2, Gnex, JROMFlasher, TWRP, CWM, PdaNet, SDK Manager, Nexus 7 tablet USB driver revision R06, Naked Universal Driver 0.72 .
I'd appreciate any advice (apart from sending the thing back), epescially if it's in a step by step easy to follow format. So basically, my question is, how do I fix this? Is it possible to fix?
Many thanks in advance!
I just thought I'd update this, mainly to let people know what to do if they find they have a similar problem to the above.
Basically, as said before none of the fixes worked. I spent a huge amount of time trying everything. So in order to save people massive amounts of time who have pretty much the same problems as I had and spending hours upon hours trying fixes like I did, then the best thing to do is to return your Nexus 7 to where you bought it for a return.
Mine was subsequently discovered to have a hardware fault so I was basically trying to fix the impossible. If you find yourself in the same boat after trying the fixes, and they don't work after a couple of tries, don't do it multiple times like I did. It's just easier, less frustrating and will save you much hair loss, anger and general irritation to let Asus fix it.
Yes, I know some of us get a bee in our bonnet about fixing it ourselves and see returning it as the last resort (like me), but anyway, trust me, just send it back, and save yourselves the trouble in a case like the above.
My tablet has arrived back repaired and works again. The hardware fault was covered by the warranty.
I hope anyone who encounters the same issues as I have manages to find this of use in the future!
Hi guys!
My Note 8.0 had the problem of rebooting whenever an app crashed. The screen would just display the status bar, the rest of the screen filled black. The device did not react to taps on the touchscreen, and after some 30 seconds, the device just started to reboot.
A quick Google on the topic led me to a few threads where people seemed to have had similar problems, but only resolved them by changing their device - but I did not want to give my new Note away
I had rooted my device right after I had bought it using the simplest possibility - Framaroot. The Aragom exploit had worked immediately and I was enjoying root on my new Note 8.
As I realized that the rebooting problem was not just a random event, but happened every time an app crashed, I started suspecting my root of being the problem. I unrooted the device again using Framaroot, and run a small app I wrote that does nothing but crash with a NullpointerExpception. This test app had led to a reboot on the rooted device, but after the unrooting, the screen only froze for a short amount of time, then a message was displayed saying the app crashed - hurray, no reboot.:victory:
Just to test, I rerooted using the same procedure as before, and the reboot returned.
At that point, I knew how to get rid of the reboots. But still, I wanted to have root access on my device.
Solving the problem was as simple as choosing SuperSU in Framaroot instead of Superuser. Once I had chosen this option in Framaroot, the reboots seem to have gone.
I don't know if that was a known bug of SuperSU (don't know the version that came with Framaroot).
I hope this helps anyone with similar problems.
Also, I am curious to hear if anyone else has made the experience that rooting with Framaroot, choosing the Aragom exploit and Superuser as the superuser app led to frequent crashes?
There are two different proven and stable root methods posted in the note 8 original development subforum by trusted and well known devs. If you use rooting methods posted outside of xda or elsewhere, you are looking for trouble.

My N7 16GB WiFi, rooted but stock, updated successfully to 4.3 some time ago. Basically, I used Voodoo OTA to save the root, let the OTA do its work, then restored root using Voodoo OTA. It's worked flawlessly since then.
Suddenly, after weeks with no issue, it started insisting it had to install 4.3 from a downloaded file. It nags constantly, which makes it hard to use the tablet. I've got CWM as the recovery so whatever file it's trying to install won't work from there. The only way I can find to go back to stock recovery involves wiping the tablet. I don't want to do that, unless there's no other alternative.
I looked for the update.zip file in the location that the tablet insists its stored at (root of SD card), but there's no file there by that name that I can find. It only shows up if I allow the nag screen to try and install it. Of course, CWM says that it can't verify the file and aborts the install. Which puts me right back at the ever-present nag screen.
Just to be clear, I am already running 4.3. This whole situation came up months after I'd upgraded. Is there anything I can do to stop the upgrade notices, short of running a factory reset and having to set up the tablet again from scratch?
May have found an answer. Used Wug's toolkit to force-restore the standard recovery. Had to do some old ADB driver removal for a bunch of other Android devices first. Appears to have deleted the unnecessary update file as part of the process. Will keep an eye on it going forwards, but think it's good.
Nope -- didn't work. Had to do a full factory reset/restore to out-of-the-box condition to get it to stop constantly trying to re-upgrade to 4.3. Annoying.
Hi,
I am trying in vain to fix my friend's Nexus 4. She started having problems with a boot loop around the same time as 4.4.3 (I think) but it just went away. Two days ago it came back, possibly around the time of 4.4.4 seeding, however this time it won't go away. I have been looking at threads throughout XDA for help and tried this thread for help. I have a GS4 myself and very little experience with ADB/SDK.
All efforts have failed. As well as the boot loop issue, recovery is broken limiting my options. I tried the "not lose any data" method in the link above but this didn't work. Next the Nexus Root Toolkit, however most of the time the program fails as it says the download failed due to an MD5 mismatch. I have tried downloading the images directly from Google but still no luck - of all the 4.X images available only a couple will even allow me to try and install.
The first install didn't install, I noticed it mentioned the bootloader been locked several times - it recommended 'force flashing' providing I definitely have the right image. Several attempts later I managed to get the install working but it is still stuck on a boot loop (waited at least 15 minutes). Recovery is still broken. The only thing I have been able to do is unlock the bootloader.
So is there any hope? The device is pure stock, no alternative custom recovery or ROMs. Thanks.
I think half the problem is I can't the USB drivers installed properly as the device isn't showing in Device Manager. Without been able to turn on the phone or enable USB Debugging, it won't let me.
EDIT - I tried another toolkit and eventually managed to get 4.2.2 installed. I have just updated the phone to 4.3 but it's been on the Google X screen for a while now
EDIT 2 - Fixed the above. I needed to downgrade the radio. Updating to 4.4 - no doubt I will go through the same hurdles.
EDIT 3 - An error occurred during installation.
Hi guys,
I have searched around the forums and still unsure, weary of what to do. I got my nexus when they first came out. I used it for a while and eventually unlocked it so that i could get certain apps that needed root access. I dont think i flashed a custom rom on it though. I havnt updated android to 4.4 yet. Its been a long time since i updated anything. Hence the start of my dilemma. I went to backup my tablet. It told me SuperUser or the bootloader needed to be updated. So im like oh fine update. Tablet then restarts brings me to my boot screen and says downloading target do not turn off. Its been stuck like this and nothing happens. I held down the power and rocker buttons and got back to boot option screen. Here's where im lost and dont remember what to do. I have tried start, recovermode, restartbootloader, and nothing seems to work. They all bring me back to the dead little android guy
Here's the device info.
product name: manta
variant: wifi
h/w version 8
bootloader version: mantam03
carrier info: none
serial: ****
lock state: unlocked
reboot mode flag: recovery
I slightly recall when i first unlocked it using twrp or clockworkmod? I could be wrong. Either way i no longer have the rootkit nor the computer i originally used to unlock it. What software do i need to install to get me back up and running. I was worried i may brick it if i installed the wrong version kit. That maybe newer version wouldn't work with my n10 because it was running an old version. Any advice would be much appreciated.

Considering that you have not used the N10 in a very long time your user data may not be all that important so here are some options.
1) You could flash the factory image for Android 5 which will wipe out your user data but give you a clean system including stock recovery.
2) You could flash the factory image for Android 5 but first you need to change the "flash-all".(bat,sh) script by removing the "-w" option which will prevent your userdata from being wiped. That takes some knowledge to edit the script but all you need is a simple text editor.
After either of those options you can root and replace your recovery. Root before you change your recovery or you will run into an issue due to specific changes in Android 5.

Good Luck
I'm having similar issues! When trying to install lollipop over sideload it always errors and states not enough space.
I've formated all the data so I'm at a loss.
Any ideas to install lollipop?

I'm concerned I've bricked the device. To be honest I'd be happy just to get kitkat back!
When the device powers up it automatically goes into a "no command" bootloop. With the android on its side with an exclamation point sign coming out.
Holding power and the volume it then goes to the android recovery where I have four options: reboot, apply update from adb, factory reset, wipe cache.
When in command, typing adb devices shows my device.
Using adb sideload I've tried to update, but I always get the error "creating parent of system/app/KoreanIME/KoreanIME.apk failed. error no space left on device
E:Error in /tmp/update.zip
status 7 installation aborted"
So I downloaded the kitkat image and tried to run the script "flash all". But then the command screen just says "waiting for device"
After all that failed, I tried to hold power and the volume button when it restarts. That takes me to the odin screen, where it just states "downloading, do not remove target" The volume buttons do nothing. pressing the power button just reboots.
Any help would be much appreciated!
I have the same issue. There does not seem to be a way to install any (old) version of android. All I get is the same error message "creating parent of system/app/KoreanIME/KoreanIME.apk failed. error no space left on device
E:Error in /tmp/update.zip status 7 installation aborted"
I did not root my device nor did I install a custom rom. I just started installing the OTA update and that's when the tablet got stuck in the boot loop thingy.
I also searched the internet and all I found were similar instructions on how to install factory images etc. using adb sideload.... as I mentioned, following those instructions lead to the error message.
I can' believe this.
Thanks for your help
I also have similar issue. I had non rooted Kitkat 4.4.4 installed on N10. I received update intimation to Lollipop hence downloaded the update. While installing, message regarding error came followed with message "No command" . Now nothing is done further. Even tablet is not getting power off. Periodically screen displaying Google is coming followed with message "No command" I just checked. I can enter in to download and recovery. I now downloaded also Lollipop update for manual updating.
While connecting to PC, it starts searching for driver and after sometime message flashed "Driver not installed successfully" might be due to non detection of MTP. In such case if I try to maually install then ADB also is not recognising the connected device. As novice even I do not know to install ADB sideloaded.
Can you suggest how best I can revive N10?
Regards,
Guys,
I also had the exact problem. What finally worked for is to flash custom recovery (TWRP latest version) with "fastboot flash recovery <recovery.img>" command.
Then from the recovery I installed custom ROM (http://forum.xda-developers.com/showthread.php?t=1998585), as the official ROM also failed.
Hope it will help someone.
Shleim, this seems to just have worked out fine. Many thanks for your help!
I'm still kinda wondering why it wouldn't work with the official ROM. In any case, this is by far better than having a bricked tablet and at least now I know it still works.
Awesome, thanks for this tip!!!
