I have no OS, please help!!! - Nexus 10 Q&A, Help & Troubleshooting

Hey everyone. So I thought that I would flash CM11 to my Nexus 10 last night, coming from CM10.2 via CWM. Well something happened and it wouldn't let me flash it, it said status 7 and install aborted.,I backed everything up, so no big deal right? Wrong! My backup says MD5 mismatch. So now my tablet won't boot past Google screen, except for into CWM. What can I do to fix this? I only have access to a mac computer.

have you tried the Nexus Root Toolkit? You can flash stock rom from it with just one click. I'm not sure if it works on mac, but give it a try, it's in the development section

I did just that! Thanks.

Strange Root Issue

When I saw the port for ICS come out I got really excited and flashed it right away. Then I realized for whatever reason I didnt have SU permissions so I couldn't tether to my computer. I was disappointed but I thought, "no biggie, I'll just restore from my back up." When I flashed my back up the SU app was in my app drawer but I still couldn't tether. As a matter of fact I can't do anything that requires SU but the bootloader still reads unlocked. WTF?
I can't flash a new recovery either. I tried installing from ROM manager, I tried pushing it from my computer but I can't get to the recovery any more. ROM manager says that I have CWM 5.0.2.0 currently installed but I can't get to it at all. Again, WTF?

^clearly the phone is working perfectly fine with the stock ROM from the back up but obviously I want my SU back.
Root your phone and read the development thread versus making blog posts.

Thanks for not answering my questions. The bootloader is unlocked but I don't have root and I don't have access to recovery mode even tho ROM Manager says I have Clockwork Mod 5.0.2.0 currently installed. I cannot access the recovery mode AT ALL. I cannot flash or push a new recovery but it fully boots into Gingerbread w/o any issues. What is wrong with my phone and how do I fix it.

Try from rom manager to reinstall a previous recovery version.

That doesn't work either. It goes through the prompts but it doesn't actually reboot do the installation.
I just tried unrooting and then re - rooting but that didn't work and I think that actually wiped my phone completely. I don't even know where an SD card would get into this thing.

I'm sorry but I'm just really frustrated right now. Nothing I have tried has worked. Maybe its my commands? To push that recovery image what would I type?

Is that the right name of the recovery img? Try renaming it to just recovery and see if that works.
Edit: make sure your phone is in debugging mode. And uninstall then reinstall the drivers on your computer

manually go into recovery with volume down and power flash the su.zip and u should be good to go that wat I did
Sent from my Nexus S 4G using xda premium
No suggestions have worked so far. It does not matter what the recovery image name is, whenever I try the flash it Terminal says that it cannot load "***.img" or if I try an install command it says that it cannot find "***.zip" I'm on a snow leopard iMac so I don't need drivers n such.
Let me pose the question like this, what would I do to completely restore the phone to factory condition and try to root it again? Like I said before, the bootloader says that it is unlocked but I do not have any root privileges, could not access the recovery I had before nor install a new recovery after having locked the unlocked the phone's bootloader again.

go to the link above and follow the directions for returning to stock.
find yourself a one-click root method on XDA that includes superuser, busybox, and CWM.
EDIT: Also, double check the md5 sum for the CWM .zip. use
Code:
md5 recovery-aaaaaa.img
in the terminal and make sure the output matches whatever is given on the CWM site. if they dont have one up, ask for it
NS4g one-click root app:

this will:
unlock the bootloader
install cwm 5.0.2.0
root
No commands, no messing with pushing files manually, etc. This thing has already saved me from major headaches while restoring my phone once and I've only had it for 3 weeks lol

[Q] Restoring Stock Android on Nexus 7

Hi I have a problem with my Nexus 7 (32 gb wifi only version).
My son in his infinite wisdom decided to install ubuntu on the tablet.
I went to try and restore this back to the android version but all it did was to wipe off ubuntu itself
I then went on jayceooi.com and used the nexus toolbox to see if I could reflash the images etc.Howveer although all the files were downloaded I canot get the laptop to recognise the nexus itself (even though it sems to charge the tablet). There is no menu at all to check whether or not usb debugging is ticked or not..
Im now left with the tablet without no apparent operating system. At the moment all it shows is the green android with fastboot mode but when I hit start it says booting failed.
Could someone help please before I do any more damage and I brick it completly (although I may have already done so)
thankyou for any help

Yes it can do restore back to stock. Just follow the guide to unlock bootloader so it can flash stock image then just re lock bootloader. It covers the process in op.

Ok thanks all. Seemed to be doing everything ok but its been stuck on"waiting for your device to finish booting back up" for about 30 minutes now. It did say it would take 5 to 10 mins but should i carry on waiting or abort and start again do you think?
thanks
I would reset it see if that helped

If your son re did the partitions for Ubuntu that could have messed things up pretty good. I have only had my nexus for a few days so I couldn't tell you how to fix the formatting quite yet. I would search around on how to verify and correct the partitions if needed.

Updated SmoothROM and my Nexus 7 stopped working! Can't get back into recovery.

I have had my Nexus 7 with SmoothROM on it for a long time now, I use it here and there, but I noticed it acting kind of glitchy lately especially when using the keyboard. I got 2 notifications from GROUPER (i think thats the name of it...) saying I had an update to SmoothROM (v 4.2) and that google apps needed to be updated... I did the normal crap, wiped everything, flashed the new smoothrom, flashed on the google apps, but when I rebooted it just keeps popping up saying "Unfortunately, the process blah blah gapps has stopped", then when i press ok it says Unfortunately, Setup Wizard has stopped".... and when i press ok on that it just keeps popping back up... will NOT go away no matter what I try...
On top of this... I tried going to fastboot and putting it in recovery mode but then it just goes to the main boot screen that says Google with a lock at the bottom, and it is just stuck there...
So what would be the easiest course of action here? I can't get it into Recovery mode I don't think, although I forgot how to do it in the first place, I thought it had to do with sliding the lock somewhere at the boot screen but I have tried that and nothing seems to work...
ANY HELP WOULD BE GREATLY APPRECIATED!
Update: I managed to get into the settings and put USB Debugging on
so now it gets recognized by my computer and I can view and transfer files.... But I still can't get it into recovery mode so what should I do now lol?
Should I be looking for something like this " Google Nexus 7 Toolkit V3.2.0 " ?
Use wugs to restore to stock and start over
If you go back to smoothrom make sure you download it again might have been a bad download

When you power on your nexus press volume down and up and power button together for a couple of seconds. Your screen will go off and then "Google" will come up. Continue pressing and you will be in the boot loader menu. Go to recovery and install the ROM you want. (Can you get there?) Or else try to install it from your PC with cmd. Let me know if the first way works.

Same here, I dirty flashed it from stock instead of full wipe. Always do full wipe just in case.
Sent from my Nexus 7 using xda app-developers app
is the lock under the Google logo open or closed? if you installed a custom ROM, it should be open. if it is closed, the bootloader somehow got locked again.
however, i think the issue you are experiencing is related to gapps. you either have a bad download of gapps or flashed the wrong gapps (some roms require custom gapps). try the volume down+power thing to get to the bootloader, then go to recovery. if you can't, flash a recovery using fastboot or use one of those toolkits to flash a recovery. before you re-flash your ROM and gapps, i'd recommend verifying the MD5 sum, since that will tell you whether the downloaded file is good or not.
Sorry for the late reply guys but as it usually goes my ADHD got the best of me and before I came back to read this i ended up using that Google toolkit thing that I asked about and did what somebody said (option 9) to download and then install the stock ROM (but thank you!!) BUT in case anybody would like to know the lock was open and I could put it in fastboot but it wouldn't boot me into recovery. Hopefully anybody else updating smoothrom that ends up in my position will find this thread. I also suggest just downloaded the ROM and flashing it with the recovery that was my first time using that update ROM thing and it screwed up lol.
Again thanks a ton! Is there any new ROMs out there for the Nexus 7? Anything better than SmoothROM (or stock, lol)?

No os installed

I installed beats audio and my phone froze. I factory reset and when I went to reboot it said no os installed. I'm scard to reboot. Lol. I'm using twrp and have ubuntu 13.10. Is there a way I can move a rom from my pc to the phone to flash?
Sorry for the noob question but I didn't find anything spicific to my question in search.
Thanks
Sent from my SCH-I535 using xda app-developers app
You can always use the toolkits to achieve your next step but if you are in Ubuntu you should go back into recovery and just flash another rom. Try Wugs and of course you can always side load a rom or flash your images back in Fastboot. As long as you are up and running you are ok.
One more thing you may only have to re-flash the Ubuntu zips to get the OS back
Edit: I see you searched so I deleted that line
OK, everything is good. Thanks.

[Q] Updated Nexus 7 to 4.4, stuck with the bouncing circles logo

Hi everyone,
I let my Nexus 7 update via the OTA update. It seemed to go OK but now when I boot I just got the Google logo, then these "bouncing" circles that appear to have taken the place of the original boot animation.
It doesn't seem to boot any further? Can anyone help?
I had this last night when my device updated, I just turned out off and back on and it seemed fine but I did lose root access,

I had this problem when I had a custom kernel on the device. If that's the case for you, just fastboot flash the boot image from the Nexus Binaries page.
Otherwise, you might need to adb logcat to see what's going on. For me it wasn't obvious what was up, it just kept getting to a certain spot in the boot and dalvik was crashing. I just figured it out by trying stuff.
If all else fails, you can try flashing the whole system as well, start fresh in case you've made other modifications to the ROM, although OTA's usually fail in those cases.
I do have cwm installed.
