Hi,
Regretting this now but was trying to try out a different ROM after a long day so probably missed a step somewhere....
The situation now is that following normal procedure, my Nexus was wiped of user data, new ROM zip file copied across and loaded using recovery mode. After that, it had some error setting permissions with the new ROM and did not install properly (loaded but blank screen, apps, settings etc would not load).
I tried the process again and the same result, but now, I cannot even get adb working, the device is coming up simply as an unknown device and I cannot force install the google usb driver to get adb working again - so now I cannot even copy stock across to the Nexus.
My question is, without adb working now, have I fully bricked it or can someone point me in the right direction?
Thanks
If you can get into boot loader you can fix it.

To elaborate a little, you'll want to get into the bootloader using the method quoted above, and then use fastboot (or nexus toolkit) to flash a stock image.
Thanks guys, managed to recover back to stock via fastboot and the command line just now .... this will teach me never to try flashing any ROMs when half asleep!
Thanks again :good:

I need a lot of help with my Nexus. I have been trying my best to root it but it won't work using the Nexus Root Toolkit. So I decided to go try rooting it manually. When I did that the same problem was coming up which is it wouldn't let me flash anything on the device to give me root access. I decided to follow a guide to bring the version down to an older version and start over from there which I tried doing manually using windows command prompts. It told me to erse boot, cache, recovery, system, and then to flash the downloaded bootloader and version of android. When I got to the point where I had to flash the new bootloader my device froze while my computer was sending the file over which is what it did every time I tried to flash or send a file to the device using fastboot. I paniced and tried again using the Root Toolkit. It wasn't working either. Now my device is saying 'Booting Failed' which I assume is because of the fastboot erasing commands I did before. I am panicing because the new bootloader is still not sending over and I've been waiting for the past 10 minutes. The file size is only (2072 KB), I don't think it should be taking this long. Can anyone help me please?

That's the guide I used to try and fix the first problem.

For the first time I did an OTA while rooted. I upgraded to 4.3 and now I've lost the following:
SuperSU dowsn't work
Busybox does't work
Can't run bootloader or recovery
My system still shows as a rooted system upon boot. When I connect to my pc and run wugfresh's toolkit, it fails to find adb. I have verified that the driver is installed correctly and debugging mode is on. I can't unlock, root or even return to stock. I do remember seing a thread about a similar issue quite some time ago but I have been unable to find ut. Any help will be greatly appreciated.
Btw, it has just a plain root, no custom roms installed.
Thanks in advance.

Hi, stator...
Your post isn't quite clear... does the device boot normally? If so, you should have no problems booting into the bootloader.
But first download the latest UPDATE-SuperSU-v1.51.zip to your Nexus 7.
Shutdown the Nexus as normal. Then press and hold the VOL down button... whilst continuing to hold, press the POWER ON button.
This should boot you into the bootloader (in fastboot mode).
From there, and from your PC, Fastboot flash a custom recovery... (Chainfire recommends TWRP)... with the line...
Code:
fastboot flash recovery recovery.img
Where recovery.img is the name of your custom recovery. I usually just rename it to 'recovery.img' (without quotes) anyway - makes for less typing at the command prompt.
Ensure you get the correct recovery for your device....
TWRP for Nexus 7 Wi-Fi ('Grouper') or TWRP for Nexus 7 3G ('Tilapia')
Although a new version of TWRP is now available (2.6), I had some weird issues with this... particularly when copying Nandroid backups off of my Nexus 7 to my PC. Random 'permission denied' messages would crop up running an ADB PULL command... copying via MTP didn't fair much better either. TWRP 2.5 works without problems though, and it's the version I would recommend.
Anyway... back on topic...
Upon completion of flashing TWRP, boot into that recovery (whilst still in the bootloader)... and select INSTALL... navigate to the folder where you downloaded Chainfires SU root updater (usually, the 'download' folder)... and SWIPE to confirm.
Reboot as normal... you should now be rooted. This can be confirmed by any one of the numerous Root Checker apps available in Playstore.
I haven't experimented with busybox... if you mean this version, I haven't installed it, and nor am I going to... at least not for a while.
My Nexus 7 is still in the process of being rebuilt from the ground up, after having fastboot flashed the factory image, necessitating a full wipe (I was running a custom ROM/Kernel combo before)... so I'm taking this slowly, re-installing apps carefully.
It seems that some apps that worked fine under 4.2.2 are broken under 4.3. MX Player and Adobe Flash Player to name a couple.... but QuickPic and Titanium have now been fixed and work fine under 4.3. I'm under no illusions that Adobe Flash Player will be fixed anytime soon... it's been technically deprecated by Adobe for a while anyway.
Anyway... good luck... and hope you get root sorted.
Rgrds,
Ged.
I am having problems with Busybox as well even though i did not take the OTA. I flashed CleanRom, and Faux kernel.
Just fyi

First and foremost I would like to apologize for taking so long to reply. Real life had me out of town and I didn't have my tablet with me. I tried the advice given but it didn't work at first. It took multiple attempts but I finally got my tablet back to stock. I guess my Nexus 7 didn't agree with the 4.3
OTA while rooted. I can now unlock, root, and even change roms once again. I don't know for sure what was causing the problem but it's all good now. Also, I was always able to use my tablet during my little crisis. I was just unable to unroot or even flash a new rom. Thanks again for all the help.

I sincerely hope this is a joke. I most definitely said thanks. I even apologized for taking so long to reply. Please try to be constructive or don't bother to post. I've been frequenting this site for quite sometime although I've never posted or even joined until recently. This community has been extremely helpful. The last thing that is needed is another troll. Thank you.

Heya...
On my 16GB Grouper I had installed the stock rooted 4.3 rom. Yesterday a system OTA update message appeared on my screen - 1.7 MB. I let it download and install over night and just went to bed. Came back in the morning to a boot loop where the device got stuck with the four colorful thingies animation. I can access the bootloader, but the recovery seems to be broken. Can't remember if I had anything other than the stock one... Anyways, now I'm strugling to get this thing going again. I am a zero at ADB but willing to learn whatever is necessary to get me started with a working recovery at least. No tool root box will do anything really for me...
Thanks for your help in advance
Hey!
Had a problem just like yours. If your running windows then install this program its called nexus tool kit. I'm a newbie here but if you Google 'nexus toolkit wug fresh' you can find it
All you need to do is plug your device in and open the program, then select flash OTA with the boot loop option and then follow the on screen instructions
That should put you back to normal with a fresh start meaning all you data will be lost. You can also root from there to.

Yeah. It would be dumb to actually learn what you are doing to your device. You should totally use a toolkit.

Thank you guys. You might not believe it, but I'm not a newb to Android or flashing. It's just that I've always been playing around with Samsung devices and there you'd normaly turn to Odin in case something went wrong. Here it's different.
Anyways, with this comprehensive guide I've been able to reflash a recovery image and my old rom. Unfortunately losing all of my data in the process, but there was no way to save it.

Hi,
I have a Nexus7(2012) I was previously running Paranoid Android and tried to update to 4.4.
I am using CWM recovery and I used the factory reset option in before I flashed.
The 4.4 ROM didn't work (because it was an ota update). When I tried to boot back into Paranoid Android it wouldn't go past the google screen, and after waiting on the screen it would put me back into recovery. I also don't have a backup to flash. I am also really bad with the fastboot and adb stuff. I just want to put 4.4 on my device, how do I do that?
(I can't transfer anything from my computer to nexus 7 because my computer won't recognise it. But it will make the USB connected sound.)
Thanks for any help!
It also happened to me but I was update via ota and its stuck in bootloader but I still manage to go into recovery mode. I also don't like using adb fasboot but I thing that is the only way that you can bring your nexus to 4.4. But that's only my advice. Maybe other great dev can give you another solution.

Yeah I know all the commands and stuff and how it all works I've been using fastboot and adb etc since launch of the nexus 4. There's no output the commands just stop for instance when I use the flashall.bat from the factory images it wipes everything but won't put anything actually on the tablet it just hangs at the first sending and never finishes it just hangs there.
I've tried flashing the files manually swell but again they won't go on. The only thing that does finish is userdata.img but nothing else finishes going on the tablet at all turning on the tablet it vibrates twice and just boots onto the bootloader and nothing else opens not even the recovery
EDIT: Hooooly smeg it actually started working! it's alive again
Not trying to say you don't know, but the more information you give the better your help would be
Knowing what bootloader you have and if unlocked or not will help determine proper steps
Knowing the exact input/output can help as well as knowing the os you are using
Also if tab was working 100% before the attempt to return to stock, prior recovery and rom, any other issues you have had, etc
But its fine if you don't want to post this
Next steps would be
Make sure fastboot binaries on PC are up to date
Quality USB cable
Check md5sum for files you are to flash
If manually flashing stops at sending what happens when you manually erase?
What happens if you just try and boot a recovery through fastboot?
The more info you are willing to give the better your answers will be
Best of luck

Oh I apologize if I came across as being rude it wasn't my intention
It's all ok for some strange reason on the 50th odd attempt it finally started taking the data from fastboot. for some reason before hand when I tried manually the command would just sit there as "sending recovery" or whichever i tried and wouldn't move even waited 20 mins earlier just incase. i'm not sure at all what was happening there but now it's booted and fine
