Accidentally erased my OS. Need help getting it back.

Made a silly mistake. I was going to flash M-kernel to my device after updating to 4.2.2 and while I was in Team Win recovery I chose to wipe cache and system. I flashed the kernel and now when I select to reboot it says "No OS installed! Are you sure you wish to reboot?" I still have the file to flash 4.2.2 but don't know how I can get it on the device in it's current state. Any help would be greatly appreciated.
I tried this method here: http://forum.xda-developers.com/showthread.php?t=1667929 however I can't get Unmount/sdcard to work in the recovery menu and therefore can't push the OS file using the cmd prompt.

You may have to fastboot the system.img and boot.img into place. How did you root? Did you use root and unlock? Did you use wugs? Do you have android sdk and fastboot installed?
Btw, I did this too. I was preparing to flash a rom, did a factory reset, wipe system, and (understand I had just gotten this device at the time LOL) wiped internal storage. Which meant my backups and update.zips were gone. The nexus 7 doesn't seem to have a way to mount twrp from recovery to side load files so I just used fastboot to fix it.

I use Root Tool Kit to root and unlock. I have android sdk installed on the PC but not sure what fasboot is. Can you explain how to "fasboot the system.img and boot.img into place"?

If you are using the toolkit, just select your device, select flash stock firmware and connect your nexus in bootloader mode (fastboot mode, hold volume down and power when it's turned off)

How to Root without flashing custom recovery

HOW TO ROOT YOUR DEVICE WITHOUT FLASHING RECOVERY
This can be done with two methods.
ADB or FASTBOOT.
I have tested both methods and they worked for me.
I tested this on JSS15J. I am not sure about any other versions but I guess it should work.
SOME BASIC INFORMATION
Usually when you want to root your device, you must have UNLOCKED BOOTLOADER.
A CUSTOM RECOVERY is usually used to flash SuperSU to gain root access.
CUSTOM RECOVERIES ARE USUALLY FLASHED (they permanently replace your stock recovery)
In this guide, You BOOT into custom recovery by going into BOOTLOADER and then using fastboot/adb tools to flash SuperSU .
Booting is temporary and thus once you restart from recovery, the custom recovery will be gone
Make sure, you have USB debugging mode enabled. To go into bootloader you can either use adb commands ( Type [adb reboot bootloader] in cmd in platform tools directory with your device connected) or do it manually by turning it off and then holding power and volume down.
You must also have platform tools of SDK (Fastboot and ADB) for this to work. MAKE SURE YOU OPEN CMD into the folder where platform tools are present.
Try it on OWN risk. I will not be responsible for bricked devices or any damage.
ADB METHOD
Connect to your PC and make sure USB debugging is on.
COMMANDS IN BRACKETS. DON'T WRITE THEM. COMMAND WOULD BE LIKE : fastboot boot recovery.img
MAKE SURE YOUR DEVICE HAS UNLOCKED BOOTLOADER
(fastboot boot [recovery.img])--------------------- Name of recovery to be here
Mount /system and push the necessary files once the recovery has started:
(adb push su /system/xbin)
(adb push Superuser.apk /system/app)
Set correct permissions:
(adb shell)------------------------------ You have got into your device's shell
(chmod 06755 /system/xbin/su)
(chmod 0644 /system/app/SuperSU.apk)
(exit)
Reboot:
(adb reboot)
FASTBOOT METHOD
This is relatively easier as you will boot into custom recovery temporarily and then flash ZIP of SuperSU. Afterwards I recommend to clear davik cache and restart.
UNLOCKED BOOTLOADER REQUIRED
Boot into bootloader.
Type these commands to boot into custom recovery. This will not flash recovery and you will have stock recovery once you restart.
fastboot boot recovery recovery.img where recovery.img will be the file name of recovery
(After 4.4, use this command "fastboot boot recovery.img" instead of above mentioned)
After booting into reccovery, flash SuperSU and you are done.
I recommend clearing dalvik cache before leaving and restart.
And you are done.
YOU CAN ALSO USE A PREROOTED KERNEL WHICH YOU CAN FLASH VIA FASTBOOT. I AM NOT SURE IF THERE IS ANY
For information on how to retain root after OTA, please refer to this :
Update Super SU is also taken from this guide.

If you are stuck in a bootloop, make sure you have cleared dalvik cache in custom recovery.
I got bootloop when i tried with fastboot method as I was new to twrp, I explored it a bit and tried to remove system and tried overwriting data to see how it is different from CWM and check its strength. I got an error clearing cache so I rebooted into custom recovery to clear dalvik and my nexus booted fine (DON'T TRY THIS, JUST CLEAR CACHE AND WIPE DATA and restart)
REMEMBER, UNLOCKING BOOTLOADER WILL DELETE ALL YOUR DATA AND DOING WIPES WILL ALSO DELETE ALL YOUR DATA.
DALVIK WON'T DELETE YOUR DATA BUT
MAKE SURE YOU HAVE MADE A BACKUP using BACKUP PRO (non rooted) or Helium (non rooted) and Titanium Backup Pro (Daah, you are not rooted so this won't work)
GOOD LUCK

Booting into custom recovery to install root works fine.
As you mentioned unlocking bootloader is still a prerequisite.
You may want to just use the SuperSU install zip though. Though I haven't tried Superuser on this tablet, it is my understanding it hasn't been modified to work with 4.3 security. That may have changed since I last looked so if you find differently please post. SuperSU added a daemon mode to deal with 4.3 security changes.

The trick here is to BOOT into custom recovery BUT not FLASH recovery permanently. Once you restart, the CUSTOM recovery will be gone.
You can use simple commands if using Fastboot
fastboot boot recovery [recovery name.img]
This way you will install SuperSU using recovery which is relatively easier than ADB commands.
You will only go into recovery temporarily.
I also read a forum where you can preserver root even after OTA/ Updates.
[UPDATE]
http://forum.xda-developers.com/showthread.php?t=2415497
Do check that out as well.
I tried this with Twrp and superSU.
I got bootloop as I have been always CWM person so I accidently tried to delete system too with dalvik cache and hard reset and I got an error
However, I boot again into recovery and cleared wipes and the bootloop was gone

You restart your device. Boot into bootloader and use fastboot to Boot into custom recovery(command given in post above).Once Into recovery, you can easily clear dalvik cache.
And remember, it might not require clearing cache because I was exploring twrp n overwriting data n tried To delete system to see how powerful the recovery is. I will update guide now

The "fastboot boot recovery recovery.img" command is not working anymore. The command prompt returns with a "cannot load recovery" error. At least that's what it does on my Nexus 7 running Android 4.4.2.
This seems to affect Android 4.3 and upwards according to this Nexus 4 thread: http://forum.xda-developers.com/nexus-4/help/solved-fastboot-boot-recovery-img-t2380675
There's a workaround with a different fastboot command line as mentioned in the thread. I wonder if there's also a fix for the Nexus 7. Any replies would be greatly appreciated.

Those who finding difficulty in rooting Nexus 7 (2013) can use Wugfresh Nexus Root Toolkit. It is so powerful that you would find every function you would like to do on your Nexus 7, from the comfort of your PC. Also watch qbking77 's video on using the Toolkit for further information.

Softbrick?, stuck in fastboot

Hello,
I was attempting to update from 4.3 SlimBean to 4.4 SlimKat Weekly.
I booted into CWM Recovery, wiped system, cache, dalvik cache etc, and went to flash the rom.
The rom must have been corrupt or something, as I was unable to and received an error.
I rebooted and was stuck in fastboot.
From here, I've tried both Wug's Nexus Root toolkit, and the Skip Root toolkit.
Running the return to stock and unroot whilst in fastboot in either of them caused a crash of fastboot.exe and the Skip Root equivalent.
After a reboot Wug's allowed me to atleast run the program, but I received link errors, so tried again. This time it couldn't find it, unplug, replug. Link errors, cant find it and this repeated.
Skip also allowed me to after reboot, but gave the exact same faults.
That's as far as I've really got. I occasionaly get it to run, and it seems to work only for it to get part way in, sometimes after sending the bootloader, or on the bootloader and it can not find any devices.
For some extra info, this is Running Windows 8.1, using a USB 3.0 Front panel header and tried using default cable, samsung and kindle ones too.
I'm looking for any ideas? Worst case scenario is I can try when I'm back home at the weekend and there I have a PC with XP that I have used previously to fix this style of boot error.
Cheers,
WiiManic

Stop using toolkits, issues love to pop up for those who do
Make sure bootloader is still unlocked
If not
fastboot oem unlock
Flash latest twrp or cwm or whatever, just download the image and open cmd in this location
fastboot erase system -w
fastboot erase boot
fastboot erase recovery
fastboot flash recovery nameofrecovery.img
Now boot to new recovery
Go to advanced
Adb sideload
On PC go to ROM of choice, maybe slimbean
adb sideload nameofrom.zip
When complete
adb sideload nameofgappsoranythingelseneeded.zip
Reboot

[Q] Nexus 10 stuck on Google logo

Hi I've done stupid thing for myself:
i tried flashing 4.4.2 stock rom. coming from 4.2 (i think) did the usual format data/cache. then rebooted then it loops on google logo. I can go to recovery mode.

So are you rooted? Custom recovery? Looking to flash stock? What bootloader do you have? Ota flash? Fastboot flash?

I still cant get fastboot up. ive used minimal fastboot and/or SDK Package. also changed the path for environmental variables.

So more info will help, usually the more info you give the faster your issues can be fixed
Are you in bootloader mode? I take it your using windows, what version? Has adb or fastboot ever worked before? When you type
fastboot devices
You get nothing? Can you post a screen shot of terminal, of environmental variables? Are all proper drivers installed? Does anything pop up in device manager when tablet is plugged into USB while in fastboot, recovery or os? Are you using factory USB cable?

sorry about that.
im in fastboot mode with power and both volumes pressed. i can also go into recovery mode TWRP v2.5.0.0
also rooted and yes windows 7 64 bit. recovery mode or fastboot mode . it doesnt recognized my nexus.
not sure if i have the right drivers. i cant find any drivers to download for nexus 10
Does anything pop up in device manager when tablet is plugged into USB while in fastboot, recovery or os? - No
and yes im using nexus 10 OEM cable.
i really appreciate the time to help me out with this issue.

Its no problem,
The SDK should have the drivers you need, or you can install the universal drivers made by koush or a number of others as well. Just Google search or a search xda for terms like
Nexus 10 drivers
Universal android drivers
Android naked drivers
You will find many that will work just fine for you
If in cmd you type
fastboot
And you see a list of commands than you know you have it installed
When you type
fastboot devices
And you see your serial number your good, if just a blank line then you need to get tab to communicate, this is most often a driver issue. If you can't find ones that work let me know and I'll link some to you, also you may need to uninstall old drivers and than manually install new ones, windows doesn't always do the best job of picking the correct drivers

i get R32D2009DAT
Im assuming thats serial number whats the next step

Google search
Android factory images
Here you will download the correct one, latest manta for the nexus 10
Then extract the contents of the zip
Now if you want to keep custom recovery that's a good idea but if you want KitKat you will need stock or at least update to the newest twrp (as you current one won't flash kk)
So if you want twrp then google search
Twrp recovery manta
And then find the latest image, 2.6.x?
Oh and its a good idea to check md5sum for both the zip from android source and for the recovery image, both will tell you what it should be in download screen and there are many ways to check, just google search
Windows md5
There is both official and none official, I personally use Linux command line and can't recall the name of the program I use for windows off hand
Also note that the following commands will wipe all from tablet, it is good to do this but if there is anything real important back it up first
Now from fastboot, enter these commands
fastboot erase system -w
fastboot erase boot
fastboot erase recovery
Now find the bootloader image you extracted from the android .zip
fastboot flash bootloader nameofbootloader.img
Now if you want stock find the system image
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash cache cache.img
fastboot flash boot boot.img
Now find the twrp recovery image

[Q] Boot doesn't go beyond rotating circles. Help!!

I tried to search, but in vain.
Hardware: Nexus 4
Software : Android 4.4.4
For reasons that are not clear to me the machine restarted and is stuck in those 4 rotating circles, and doesnt go beyond it. Tried multiple things such rebooting, rebooting into recovery and booting again, tried adb to see if it can see the machine in recovery mode, but to no avail.
Can someone please help? Thanks in advance.

Did you do anything, flash anything to get the boot loop? Boot loop can usually be cleared by doing a factory reset. But you'll have to reset up your phone afterwards

This is a stock android and have no changes whatsoever except automatic update to 4.4.4. Only thing that is different is it is unlocked.
For last one week the phone kept complaining that it was unable to back up photos and videos. So I kept the wifi on over the night, and next morning I saw what i thought was it was trying to reboot but unable to do.
Is it possible to connect to machine while it is in recovery mode? My ADB can't discover the device either in recovery mode or while it is trying to boot. Is there a way to press some button and hard reset it?

Yes, that's the bootloader. Google 15 second adb install xda and install that. Then download the latest version of this http://techerrata.com/browse/twrp2/mako
Rename it recovery and put it in the same directory as fastboot.exe which will be installed with the 15 second adb install
Open a Windows command prompt in the same directory as fastboot and then with your phone connected to the pc and in the bootloader type the command in the command window
fastboot flash recovery recovery.img
This will instal twrp to your phone

My Biggest concern right now is not TWRP. I need to somehow get the machine to boot. It is stuck in those 4 circling things, and I need to somehow get the OS to work (or re-install if needed).
I am able to get to recovery where I see options to 'apply aupdate from ADB,' 'wipe data' and 'wipe partition'. I have wiped off everything, now I need to somehow get OS to install, and I don't know how. I tried using 'adb sideload 'image-occam-ktu84l.zip', but it fails.That file was extracted from occam-ktu84l-factory-0d3fd624.tgz from Android site.
Update: Great, now TWRP is installed. What next? I don't want CM at this point. Just stock Os. How do I get on to the machine?

I installed both TWRP and CWM alternatively, installed factory images using flash-all.bat, install CM11. But in both cases, 1. factory image : The system get stuck in boot mode where those 4 circles keep rotating around each other, 2. In CM11, the arrow keep rotating indefinitely.
I don't know what else I can do.
Any pointers? Thanks in advance.
I am beginning to suspect hardware malfunction. In which case, is there a log somehow I can see?
As an Aside: 1. Adb refuses to see the device in fastboot mode. Not sure if this is an expected behavior. Fastboot can.
2. Stock Android USB Drivers never work. I had to get the WugFresh Development drivers.

Flash the factory image in fastboot

As I said earlier, both factory image and CM go into infinite loop at bootup. I have no idea what else to do.
Question now is to see if something is wrong with hardware. I don't know how to check that. Is there a way to do some diagnostics

You probably have a failure of the emmc. What happens if you try to lock the bootloader and then reboot? Does it stay locked?

Yes, after locking (fastboot oem lock), bootloader the status says locked and I no longer see that unlocked icon when booting.
- At the moment I have CWM, and I see advanced options to format different folders which I have already done. But what I am not able to do is to use adb to copy the image-occam-ktu84l.zip to sdcard. Only way I have been able to install any zip is using sideload. Is that normal? I wonder if I am following right steps to begin with.
- Also, are there tools that can run and check if emmc has no bad sectors etc?
- In CWM I formatted whole log of folders, and now when CWM boots, it can't find /cache/recovery/* files. Which I take as a good sign - since old stuff is now gone. From here I don't know how to proceed. Any help - very thanful.

If you can side load you should be able to adb push a rom. When in recovery type adb devices. Does it show that your device is connected? Do you get an error?

I can sideload from adb. (adb sideload <filename>.zip while CMW is waiting for abd sideload). But can't push since adb doesn't recognize the device while in fastboot - the way fastboot can.

You have to be in recovery to run adb commands. The bootloader is only for fastboot commands. Try pushing while you're in recovery, not the bootloader.

Here 's what I see when I to sideload,
In CWM, I choose 'install from zip, which takes me to next page where i chose to select from sideload. I then start sideload from 'adb sideload occam-ktu84l-factory-0d3fd624.tgz' (sometime I use the extracted zip from that tgz),
Following is what I see on CMW,
'Restarting adb
Finding update package...
Opening update package...
E: Can't open /tmp/update.zip
(bad)
installation aborted'

Ok, you can't use that file (tgz) in cwm, adb or fastboot. What you can do is extract it and then use the zip file. But, you'll have to boot into the bootloader and then use the command
fastboot update update.zip
