[Q] Need help installing android 4.4 - Nexus 7 Q&A, Help & Troubleshooting

Hi all, I've messed up with my nexus 7 2013 and i think its soft bricking.
I was using multirom and accidentally installed the wrong kernel. Every time I boot into android (4.4) it loads slow and then instead of displaying the screen it shows two duplicated top left hand corners and remains unresponsive.
Unfortunately i never got the chance to enable usb debugging and my bootloader is locked.
I tried a few things suggested online but they didn't work and multiform appears to have been wiped.
Recovery still works (TWRP) but I'm really in a bind.
Any help on getting back to stock android 4.4 would be amazing, but please bear in mind I'm new to android, so please provide detailed instructions.

Probably your best way would be using fastboot, can't give you details but I have seen it on here. Google fastboot nexus 7.

Wugfresh toolkit should also work, especially if you are not familiar with or interested in learning fastboot & adb.

Thank you both for getting back to me and helping me fix this. I really appreciate it!

Rooting nexus 7 is impossible

Well unlocking the boot loader is possible but when rooting the nexus 7 gets stuck in fastboot when its suppose to be rebooting its self oh well I been at it all night so now I realized its impossible

Use the toolkit, worked great for me. I couldnt get the adb right so I tried that. My nexus 4 was easy without the toolkit though..

If you can unlock the boot loader, you can do *anything* to your tablet starting with fastboot.
Learning to install drivers is a Windows issue - the skills needed to analyze & resolve driver problems have almost nothing to do with what device is attached to the other end of the USB cable.
Toolkits are a crutch for avoiding learning a very small number of skills; if you don't want to learn those skills, probably you shouldn't be rooting.
Throw away your toolkit and read the fastboot thread. The whole process is far easier than you think.
How come y'all help everyone else but I can't even get a hint on what I'm suppose to do I'll just return my tablet and get a new one Cruz obviously its gotta be my tablet

If you unlocked the bootloader and you're having trouble rooting your device then I don't see you being able to relock the device either, which is critical to do before returning it as technically an unlocked device is out of warranty.
And you say no one is helping you, but you haven't provided any information at all. We have no idea what you did to even cause that error, and you were recommended just to use a toolkit if you want, as that is an easy approach, and you haven't responded on whether you have done that either.
Exactly, how is anyone supposed to help if you don't tell us what you did.
How did you unlock fast boot? What did you try to get rooted?........etc
User is informed of multiple posts. So hopefully, with your help, the root issue can get resolved.
User MUST tell people exactly the steps taken to replicate the error. Including PC type and Operating System.
I hope we do not see duplicated posts anymore.
So if some of you more experienced users, can do some "hand holding" and walk him through the steps, then it will be appreciated. As clearly, he has issues on his own.
Do it for XDA...

I agree 100% on Toolkits
That sounds like a windows driver issue. I had a similar issue when rooting my N7.
Open device manager
Look for Nexus 7
Does it have the yellow triangle on it? If yes, then your ADB driver is not installed, or not installed correctly
In ADB mode it should show up in the device manager as Android ADB Device (or something similar)

Yeah, this was my problem.. That's the only reason I used the toolkit. It wouldnt install right after downloading USB driver through SDK . got me pissed off and uninstalled every driver, and installed my nexus 4 all over also. Some how that one went easy..

LOL op went to yahoo answer, hilarious!
If he is still reading this, USE THE GOD DAMN TOOLKIT FFS, its pretty much idiot proof.
Yea, toolkit is the only way to go.
I think he is stuck in the same place I am stuck in. Whenever I get to the "Reboot Bootloader" in the Toolkit, it fails to go any further. I've made a thread about it here: http://forum.xda-developers.com/showthread.php?p=37524971
The toolkit isn't for everyone, unless of course I'm doing something wrong.
as long as toolkit detects your device, you can simply flash the google image and have everything reset, i dont see how that isnt for everyone honestly......
I used Wugfresh's toolkit and everything worked easily. I dont know any other way to do it, and the toolkit makes it easy for Gnex or Nexus 7.

[Q] Problem rooting with Nexus Root Toolkit

I rooted my Nexus 7 with Nexus Root Toolkit without any problems but I've just bought a Nexus 4 and can't seem to root it.
I let it update to Android 4.2.2 then ran NRT (v1.6.3) on my PC. After a few goes the drivers installed and it passed the final driver test so I assume all is well there. I then unlocked it without any trouble but I ran into problems when I came to root it.
It seemed to be going smoothly until it reached "Booting TWRP temporarily" but nothing happened, it just sat in the bootloader screen and didn't move on, although the message changed to "Rooting" and then "Waiting for your device to finish booting back up". In the end I pressed the power button which rebooted the 'phone and appeared to finish the procedure but it hadn't rooted or installed SuperSU or BusyBox.
I tried flashing it back to stock and re-rooting it but it was the same, I even re-locked it and went through the procedure again but it was the same.
Can anyone help please?

Yes, uninstall and forget about root kits and look and (most importantly) learn from here http://forum.xda-developers.com/showthread.php?t=2010312.
This is also a good source to read: http://forum.xda-developers.com/showthread.php?t=1469909
Thanks for the suggestions, guys. I still don't know why Nexus Root Toolkit didn't do the job when it worked so well and easily on my Nexus 7 but in the end I used the hippowise.com rooting instructions (using Google Nexus 4 Toolkit) and it worked a treat so I'm a happy bunny again
http://hippowise.com/how-to-unlock-root-and-install-a-custom-recovery-on-a-nexus-4/
I know it's more sensible to do it manually so that I know what has happened but in this case I just wanted the job done as quickly and easily as possible. I'll look into exactly what happened when time permits.
Cheers,
Simon.
^^ Learning opportunity lost.
Ditto, I've heard nothing good about toolkits and never used them, and consequently have never had the weird problrms I hear associated with them. Set up fast boot, setting it up can be a pain sometimes but its a one time thing. Using it is too easy and it never fails.
I do get what you guys mean and I will be interested to look into the procedures to see what's going on and how it unlocks and roots when time permits but, aside from being short of time at the moment, these toolkits are just automating the list of commands that you would issue manually so as long as someone has seen it working on the device and OS that you want, they should be fine so I'm happy to use them and learn more if/when I need to resolve problems. I am techie by nature but I'm not familiar with *nix and the inner workings of Android so it's a lot to study for something that only needs doing occasionally.
Anyway, thanks again for pointing me in the right direction and encouraging me to not be so lazy

To be honest, the learning curve with manual rooting is very straightforward. Heck, I found it quicker to unlock and root manually than through toolkits. You are literally just inputting a few lines into command prompt.

[Q] Nexus 4 Bootloop Troubles!!

There is nothing that I can find that pertains to problems with installing Kitkat factory image 4.4 on my nexus 4 so I will state my problem with the hope of some insight.
I have a Nexus 4 that I have decided to sell and as a precautionary measure had decided to flash a fresh copy of Android version 4.3 last week to ensure all files were deleted. I used Nexus root toolkit and all went smoothly.
As the phone has not yet sold, I decided that I would update the currently OS to the latest version 4.4 kitkat to make it more appealing to buyers so I went back to Nexus Root Toolkit and went through the standard procedure of selecting my device and OS, etc. The phone is unlocked. I had no backup and went ahead and told the software to write over version 4.3 with 4.4. I thought all was going well, but the install was too short and didn't work with a message telling my to try "Force Flash" mode. So I tried again using force flash mode and this time the install took longer and the phone rebooted multiple times, only this time the phone wouldn't fully boot. It only boot loops now.
-I can put the phone into fastboot mode.
-The computer can communicate with the phone via USB cable.
-All info such as product name, variant, HW version, etc. is showing in fastboot mode.
I am unable to use Nexus Root Toolkit to fix my phone with or without using Force Flash mode.
I can't mount the phone and the computer can not detect the ADB at all.
Can anyone please tell me what I can do to fix my phone? Are there any other alternatives to flashing a fully functioning version of 4.4 Kitkat?
I have been at this for hours and I can seem to get anywhere with it. Is the phone destroyed?
Any help would be greatly appreciated. Thank you in advance.

Those who face this issue can go to safe mode and backup their data while on boot screen just keep pressing up and down volume button for some time phone will get into safe mode and can be backed up.

[Q] Cannot Unlock Bootloader, Bricked Tablet

Hey Guys,
Hoping someone can help here, I have followed various tutorials I have found on the internet to try and restore my Nexus 7 back to its factory state after it one day decided to never get past the white Google logo.
Inevitably I ended up on this tutorial as the only one where I seemed to get any kind of a link and response with the tablet: blog.laptopmagDOTCOM/how-to-hard-reset-a-bricked-nexus-7-with-your-pc
basically it got as far as trying to Unlock the Bootloader, but it fails to do so. I do get the popup on the tablet asking if I want to unlock it but nothing happens, it remains locked after I click Yes. My command line saying that it Failed.
All other tutorials seem to assume you can access the OS and enable debug mode but of course I cannot. I cannot even do a Factory Reset, every options eventually leading me to a white Google logo.
I also cannot get into recovery mode, im just stuck on the screen with the green android and the option to Start, Recovery mode etc all just lead to the Google logo.
The impression I have gotten from not being able to unlock the bootloader is that there must be a hardware failure? could anyone suggest some black magic I might be able to do to fix it? I realise at some point I should cut my losses. I had also wondered if it was worth buying a new motherboard/logic board?
Would appreciate any help.
Cheers,
Matt.

Wow.....
Please stop spamming the toolkits.
The op has indicated that there is a hardware issue because the bootloader unlock isn't working.. A stupid toolkit isn't going to fix that. You should are promoting people to use their damn brains and doing it the right way, but laziness prevails, eh?
To the op, sorry but it sounds like you have a corrupt emmc. If the unlock process fails to commit, that's a bad sign.

Also to the op, USB debugging has nothing to do with the bootloader or recovery, only a booted os. Can you boot to recovery from the bootloader?

[Q] Nexus 7 "Razor" stuck in bootloop, no adb access, and no recovery

Hello all,
As one can ascertain from the title, I have my Nexus 7 "Razor" (2013) edition stuck in a boot loop, with it not able to be recognized in adb.
Now before you mob me for not making a recovery, I didn't expect when flashing an official google image to go wrong. Well, clearly, that didn't happen. Some notes that may help you in assisting me:
The bootloader is unlocked.
Originally usb debugging was enabled, however, with the current lack of OS, it appears to be gone/reset.
I am a semi-n00b with with this stuff, but I can understand about 80% of directions, nevertheless, take it easy please
Thank you for any and all help!
A. You are in the 2012 forums.
B. USB debugging only applies to a booted OS. In fastboot mode it is not needed. What image did you flash and how did you flash it?
#stayparanoid
Oh my apologies, I am a noob.
I was trying to flash the android L dev preview.
