[CLOSED] Help! Nexus 10 stuck on Google logo after Rooting attempt

Hey guys, looking for some assistance here as I am at a complete loss.
Decided tonight to root my 4.2.2 Nexus 10 using the Nexus Rootkit v1.6.3 and the aid of a YouTube video. All went swimmingly up until the TWRP wipe. The video I followed failed the wipe attempt and the guy showed how to get the N10 out of the bootloop and do a 'wipe data/factory reset' via Recovery Mode in the Bootloader and then restart.
Problem is, my wipe never failed like his did in the video (great I thought!) and so I restarted after that and now I find my N10 booting up to the Google Logo (with the padlock at the bottom) and it just sits there. Doesn't even get to the 'X' logo which should come after.
I've tried a few things including the manual wipe data/factory reset from the bootloader and restart but everytime it gets stuck at the Google Logo. I am also now at the point where my N10 doesn't show in Device Manager as it did before. It now shows under 'Portable Devices' as a 'MTP USB Device'.
I am really at a loss here and searching various solutions is just confusing me even more and would appreciate it if someone could help me out, even just getting back to stock for now. That's if it isn't goosed?
Thanks in advance

Have you tried using a different usb port on the PC, and rebooting the PC?

I have yeah. Left my PC off overnight and went back to it again this morning and same issue.
Plug it into the PC (this time using a USB port on the back) and it initially comes up 'installing device driver software' quickly followed by 'device driver software was not installed successfully', quickly followed by 'installing device driver software' again and that's when it shows up in Device Manager as 'MTP USB Device' under Portable Devices, whereas before during the root attempt it was show as 'Nexus 10'.

When I first read the subject line I thought it was "another one of these" where OP hadn't searched on the existing boards. But when I read OP I see you did try "the usual suggestions". Hoping a more seasoned pro jumps in here to help...
I can say that on the handful of "really bad" posts like this that I've seen they usually end with the person saying something like "well I don't know what happened I just kept trying all the power button / charge recommendations and finally it worked" - so don't underestimate the effectiveness of repeatedly trying it like a mad man!
Some random suggestions I have that may help:
-Can you leave it on, on the Google screen, to where the battery 100% drains, maybe this could act as a "battery pull"
-Try a different USB cord
-Try rebooting it via the power buttons while the device is plugged into the wall charger
-Download the Android SDK, then use its "update manager" to update its USB drivers to today's definitions
-Try another PC
Good luck!

Thanks for the suggestions bigmatty, I'll certainly give them a go when I get in later.
I think my biggest concern is that there doesn't seem to be any OS on it, possibly to do with the wipe during TWRP and then I rebooted - was I supposed to reboot at that stage? That's where I got into this loop. And now it doesn't detect it as 'Nexus 10' in my Device Manager on my main PC. Only this MTP USB Device - sometimes showing a conflict warning triangle, sometimes not and no longer showing as a storage device in My Computer.
I did connect it to my Netbook (Running XP) earlier and it detected it as an 'Android Device' under Other Devices in Device Manager. Tried installing it with the naked drivers on the Android SDK and it now lists it under 'Android Device' in my Netbook's Device Manager as a 'ADB Device' (I think, would need to double check as I'm not on it at the moment.)
I just want to find some way of getting it back to factory settings and stock OS if possible and then take it from there again. Don't fancy at £319 paperweight! I'm usually alright with these things too.
Thanks again (And if anybody else has any other input in the meantime I would be grateful - I'll try anything at this stage!)

I'd say its a good thing that the PC exhibits varying behavior - because that means there is still hope!
It really boils down to if you can open an adb.exe shell to the device. Can you? It would not be when its showing as MTP but it would be when its showing as adb in Device Manager. If you can then here is a thread where I explain (pretty good, I think) how to get back to stock:

Now I realize Im not clear on a second avenue - can you still get into TWRP?

Can't really get into much on the Tablet itself. It boots up, gets to the Google logo (with the padlock symbol at the bottom suggest it has been partially rooted (?)). I can get into the Bootloader by holding down the Power + 2 vol buttons. Once in the Bootloader I have the options of Start/Power Off/Recovery Mode/Restart Bootloader.
When I go into Recovery Mode I can get access to the blue menu where I get the options to restart/something about adb/wipe data/factory reset/delete cache partition (paraphrasing here).
Don't know how many times I've tried the wipe data/factory reset option and reboot but always get sent back to the same loop.
I'll give you're other idea a shot as well later. Thanks again.

bigmatty, you the man!
Managed to get back to factory stock following yours and styckx's guidelines. Couple of little teething problems along the way but nothing I couldn't get around.
I now have a fully functioning Tablet again and I thank you for it.
Might give the Rooting a miss for now but if I come back around to the idea I'll be sure to follow the guides on here this time instead.
Thanks a bunch again for taking your time out to reply to my thread and get me back up and running again. :good:

[Q] Hard Brick D800 - Please Help! At a loss

Any help is appreciated! First some background:
Flashed device to stock using KK 4.4 version d80020c following steps found here http://forum.xda-developers.com/showthread.php?t=2432476. Successfully rooted using directions (and ioroot25) found here https://www.youtube.com/watch?v=HKuedInhdjU&noredirect=1.
Here's where I got into trouble...Downloaded TWRP 2.7 recovery img and flashed via Flashify. Since this step, my D800 has the exact same symptoms found on this thread http://forum.xda-developers.com/showthread.php?t=2582142.
- No download mode (tried many times)
- No recovery (tried many times also)
- Secure booting error
- LG detected as qhsusb_bulk in device manager
- Device is recognized as 15 different drives, one of which contains a folder named image with 79 different files being .B0X files and Microsoft Access Add-in Data files
- Upon restarting, LG logo with secure booting error, then the screen goes black while your phone is still on
I've followed the steps in the thread that matches my G2's symptoms, run ubuntu 13.1 in VM, apply usb filters for my device which is then recognized as either LG Electonics Inc. QHUSB_BULK or Unknown Device 05C6:9006 when running in VM.
Upon running command ls /dev/sd* in VM Ubuntu Terminal, all that is returned is /dev/sda /dev/sda1 /dev/sda2 /dev/sda5 which are the partitions for Ubuntu, no LG.
I've tried to download and update the Qualcomm drivers, device manager tells me that the drivers were recognized, but cannot be installed and do not pass the hash check (Note: PC is running Windows 8.1).
I've spent over 12 hours on this trying to fix this problem, researched and searched everywhere. If I could get ubuntu to recognize the device, I would be able to continue on with the instructions on this thread http://forum.xda-developers.com/showthread.php?t=2582142.
Links for windows 8 qualcomm drivers, suggestions on how to get the device recognized in ubuntu vm, experiences from others in similar situation, or any with experience working with LG to get a repair done if I'm SOL (as in eMMC is fried) would be so helpful right now.
Thank you all!

After flashing recovery did you flash a patched kernel to boot stock kk?

I had the same, also with a lot of drives etc.
Screen is black but low backlighted?
Then try with pluged USB Cabel in Phone, hold Power button until screen is realy off, then hold the Power Up Button and plug Cabel into PC.
So I got download mode after I tryed many times

I had problems a few weeks ago getting mine to go into Download mode... turned out that the cable I was using was great for charging, but sucked for everything else. Once I switched to a different cable things worked fine and I was able to load D80010c on the device.
I was running D80020c this morning (with the D80010c boot.img to have a custom recovery) and decided to do an update. Since you can't load D80020k if you have the older bootloader I went all the way back to D80010c, updated to D80010o, D80010q, D80020c and finally D80020k. I was able to root that using IOroot and have restored everything back onto my phone.

Thanks so much for the responses! I've tried endlessly to get the device into download mode, and tried a new cable to no avail. Any other suggestions?

The URL you've linked to will help you solve your problem.
So once you power off your device, hold volume down and power till the lg logo shows, then release shortly and hold them again together till the white window with "factory reset appears", you should notice a text behind the white screen it's fine. So right now when you think it's gonna enter recovery mode the screen is gray(not black), now you connect your device to your ubuntu or whichever linux. You will notice the screen repeatelly blinking when linux is trying to automount the partitions. Figure out which device it is according to the messages it throws. (sdc, sdb, sdX)
This way you should proceed according to the instructions on the thread you linked.
d800 partitions are here

Still no luck

Thanks for your advice.
I got the white screen asking whether or not I want to perform a factory reset. If I choose No, the phone sends me right to the LG Logo with the error screen. If I choose Yes, it does the same thing. If I plug my phone into my computer while on the white screen asking if I want to perform a factory reset, the device isn't recognized and the PC doesn't see it as plugged in or mounted. I'm not sure what you mean by the timing of when I should try to plug in my device. Thanks again for all your help.

As soon as in the background of the white menu (factory reset) the secure boot appear plug it in. I'm not sure how much usb filter helps you(maybe it does) but try installing ubuntu over WUBI installer so your win remains. Or at least try ubuntu from usb stick. So you can know for sure if it's working.

Hi Sneaky E. I have the same issue you have. I'll be following your thread. If I figure anything out I'll let you know. I am also having an issue getting mine to charge now. Have you tried downgrading your TWRP?

I've tried all USB ports, 2.0 and 3.0. I feel like if I can get past this there should be no reason linux can't see the partitions in the phone. Please Help!!!

Ok so thank you for your help so far. I was able to install Linux on a USB drive and ran the commands and pushed appropriate files from there. I pushed all files including recover.img but the phone will not boot into recovery. Please help!
Thank you!

you are not alone dude. i had the same issue since sunday and i have spent almost 46 hours already trying to restore my LG G2 F320S korean model.
i followed that instruction in linux, everything went well but then I ended up with a phone not going past the LG logo. the screen no longer dims like how it used to with the secure boot fail error. again, it stucked at the LG logo and thats it.
pressing the 3 buttons though for 5 seconds shows a white screen with 3 options and a bar code under.
but all of these options will just take me back to the LG logo.
I went to a phone technician today, and they said the doing a JTAG fix is the only way to resolve the problem because after trying to fix it with linux, it is no longer identified by my PC.
what are your solutions so far?
anyways before this issue came up, i tried to flash TWRP using flashify, it failed. then went back up. tried to update the OS via OTA then thats it.
i home someone could help us out.

USB connection failed, stuck on boot logo.

Hello friendroids,
First I want to say that I have already searched if someone had the same problem as mine. I cannot guarantee I have been through all the threads already posted but I tried to investigate, finding solutions that were not suitable to my case.
1) Explanation of my problem:
As a good noob I tried for the first time to root my Nexus 4. I am using a Mac Book Pro running OSX 10.9.3.
I have managed to unlock the bootloader but can only run the Recovery mode using ClorckworkMod Recovery v6.0.4.3.
I have already done "wipe data/factory reset" and if everything had went well, the next step was to reboot the system and install "UPDATE-SuperSU-v1.80.zip" using Android File Transfer.
Now this is when I think I did something wrong. I cannot remember for sure but I think I said "no" twice at the screen that said "root[something]", that did not appear in the tutorial I was following. Unfortunately I cannot remember the "something part" because the second time it just rebooted itself and got stuck on the booting animated colored bubbles. So I tried to turn it off but I might have unplugged it before it was off. I could not turn it off straight away (maybe for misusing the physical buttons...) and my screen was saying "DOWNLOAD MODE DO NOT UNPLUG the device until the process is complete." At that time I had my phone plugged again before seeing this screen.
Then I turned it off, booted the recovery mode, and following the Q&A section of the same tutorial, I wiped the cache partition and the dalvik cache (several times).
2)Question.
So now I am stuck on the same booting logo, unable to exchange files between the Nexus and the Mac through Android File Transfer. The good news (if I may say so), is that the battery is still charging through the USB cable when connected on the Mac.
Has anyone any thoughts on how to help me finish to root it, fix the USB connection and install OmniRom (in whichever order you want)?
Thank you very much for reading and for the general purpose of this forum. :fingers-crossed:
PS: Can I put a link of the tutorial I was following for better understanding of my problem or is against the rules?

If you just want to install omni rom then you don't need to root you device. Download the zip file and flash it using custom recovery or sideloading. Since you cannot boot you will have to go with sideloading.
And yes, you can post the link of the tutorial.

[Q] Fastboot working, but no Android...

I have a Nexus 7 2012 (KOT49H, nakasi) which will only boot into fastboot, but not to Android.
I don't know what caused this - when it happened first I rebooted, and it worked again for another couple of days, then I got a "Google Play Services has stopped" message, so I tried to power off and reboot the tablet.... and it won't reboot!
At that time I was unaware that such a thing as USB debugging existed, so it's not been set... Indeed all I know about these problems now is what I've found out here... so sorry if I test your patience!
What I have done:-
I have tried a factory reset, with no effect.
Tried Wug's toolkit, which was unable to do anything (as USB debugging not set?)
(Windows 7 appears to have the drivers for this - it appears in Device Manager as Google Nexus 7 Bootloader interface)
Tried Skipsoft's Toolkit, which succeeded in unlocking the bootloader, and I have flashed images (downloaded from google) for Boot and System to the appropriate partitions... still nothing! Flashing the bootloader image failed ("An error occurred")
Is this Nexus destined for the dustbin? It is, of course, out of warranty :crying:
Apologies if I've done something daft, but I'm getting desperate...
Can anybody help?
Many thanks

hEY,
i got the same. I tried to install cm11 and i format sd card and happens that i formated the system too.
Now i can only to restart in revory "cwm v6.0.5.0" but cant start in download modus with Power+down (see only GOOGLE LOGO with open lock sign).
With wugs fresh i got the same with the f**** usb debugging enable thing, i cant get into nothing only in cwm.
I would be sooo happy to find a tool like (adb-tool) how i can put files again on my nexus 7.
thank you guys in advance!

If you have wugs, you already have the adb tool on your computer. Look in the wugs directory. However it sounds like your drivers are messed up. If that is the case nothing is going to work until you get that corrected.

Probable brickage of TN7

Hi folks,
So, after little usage due to instability caused by the Lollipop upgrade I hadn't used the TN7 in a while. Yesterday I thought I'd have a go at reconditioning it.
Background: The bootloader has been unlocked, recovery was TWRP, I'd flashed and reflashed stock ROMs of KitKat and Lollipop several times previously. The main problem in Lollipop was that whilst the SD card files were showing up fine in FS Explorer, I couldn't see any of my files or folders when looking at local storage. Also, Google Play Services refused to update (or install using an APK).
Yesterday I grabbed the factory ROM from the nVidia site to do a full factory install and reset. I followed the instructions, flashing the recovery, boot, system, userdata, staging blob and dtb in that order. I then rebooted and...nothing. No power (or so it appears), no boot screen, no ability to get back into the bootloader, nada, zilch. When I read back through the flash commands I noticed that the final part of flashing the system image failed, which could well be the cause - I should have paid more attention.
I've searched all over and tried multiple options to get the TN7 to boot or show some signs of life. I don't even get an LED showing when plugged into a wall socket to charge.
The device doesn't show in fastboot or adb on the Mac. I did however get a small sign of life from Windows. If I hold down the power button for around 10 secs and let go, I can hear the Windows chime of a device connecting, immediately followed by a disconnect sound, the Device Manager updates but shows nothing new.
So my question is: have I completely screwed the pooch, or is there something that can be done to resurrect it?
Cheers for reading,
Gray
