Nexus 7 - No Android installed, outdated recovery, fastboot not working - Nexus 7 Q&A, Help & Troubleshooting

I need help with my nexus 7.
Heres the story:
NEXUS 7 was owned by my little brother. He installed a tons of games, and tablet was unusable.
Then, i fully wiped the tablet, and tried to install android 4.4 (prev version was XenonHD 4.2.1), but it couldnt install it, as recovery was too outdated to install the newest android.
So, now i dont have any android in the tablet, and i am left with recovery and fastboot.
I have to update recovery, so i can install new android, but fastboot is only saying "waiting for device" and nothing happens.
Is my tablet bricked? I cant install android, cant move files to /sdcard, cant fastboot and so on...
I know, that there is a way, but i dont know how.
Please help. I need this tablet tommorow for work!!!
Regards

bump.... Please help...

If you can still access the recovery download a rom that is compatible with you recovery and flash it, but I think you need to have access to sd card then so what you should do is push the file to your device when in fastest, I know it is possible but I don't know how to do it

Try stock 4.2.1 from fastboot, then 4.3 etc.

*problem solved*

hi there, i have a problem with my nexus 7 and i have searched around for some answers i cant seem to find any for my problem.
so the story goes:
i downloaded the nexus 7 toolkit by mskip and i used this to unlock the boot and root my device, this worked fine. I then decided to try another rom, so i copied the zip to the sdcard (or so i thought) and using the toolkit i used option 11 to install the recovery-clockwork-6.0.1.0-grouper.img, (i selected option 1 intall in /boot, i assume this is where i screwed up) this too went fine. but i couldn't install the new rom as it was no longer there, and now i cant get my device to do anything except boot into cwm or i can go into fast boot.
any ideas on what i can do?
i have looked for the default .img to try installing that but i cant seem to find one.
thanks for looking.

dont use a toolkits. download the rom via your phones browser, go into recovery and flash it. anyways, you should try twrp recovery, its better than cwm and not buggy

unfortunately i cant do this as i cant boot into the androis os, i have stupidly overwritten the original boot.img located in the /boot folder, i think i need a copy of the original boot.img to be able to get into android and then get me a new rom

Do you have adb on your computer? Fastboot?

yes i do, but i get confused using those, which is why i used the toolkit to unlock and root my device. unfortunately i got a little carried away and installed cwm into the wrong directory and overwrote the boot img.

cant you reach your storage via your cwm recovery? you should be able to transfer files from your computer to device still.

i've tried to do this, but it wont let me mount the /scdard, im not sure why, but it maybe has something to do with how i installed cwm on the device, or maybe im have driver issues
UPDATE = i fixed my device, my stupidity knows no bounds, i found an option in the toolkit to download and install the factory standard rom with all the gubbins attached including the boot img so i okay for now untill i find something else to screw up

[Q] Stuck in boot?

Just rooted my nexus 7, 1-click with the toolkit and i wanted to install the tablet UI patch. I installed the Odex version of the patch, and now im stuck at the big Nexus X on the boot screen. It wont loop, it just sits there. I dont know what to do. Cant pull the battery like im used to because, well, you know. Any suggestions?
Edit: Made it into bootloader/fastboot/recovery. Im still stuck. I dont have any back up, this should of been a simple little patch and i would be done. is it possible to transfer files while in fastboot or recovery?
What recovery? Some can mount usb and then drag-n-drop. But if your in recovery and have the right drivers, you can push the file adb. Or use a toolkit.

[Q] Iam not able to install a custom recovery

Hey, just got my N4 yesterday.
I rooted my device today.
I also wanted to install a custom recovery like cwm or twrp.
But everytime it comes up with the android figure and a red warning.
Seems that every tool kit like the 1.6. nexus root toolkit or the Google Nexus 4 ToolKit is not able to install/flash a recovery.
Am i doing anything wrong?

What you are doing wrong is using a toolkit. Follow these instructions. http://forum.xda-developers.com/showthread.php?t=2018179
I use mskip's Nexus 4 Toolkit without any issues. So far I've used it to root, install clockworkmod recovery and flash the stock image after messing up a build prop edit. Saved me a lot of headaches as I haven't used adb or fastboot commands in over a year, don't even have the sdk installed any more. This is the first phone since I got my Incredible in 2010 that I actually wanted to put a custom recovery on and play with.
Here are some basic questions. Did you unlock your boot loader? Do you have usb debugging enabled? Does your device show up when when your plugged in and booted up into fastboot? Do you have the correct drivers installed? Which recovery are you trying to install and did you try the other one available? Did you use the toolkit to root and did it work?

After you root the device using the toolkit, it is easiest to download ROM Manager or Goo.im from the Play Store to install your custom recovery.
As Ed Daddy said, it's best to use ADB, however, it would save you some times and a few headache if you could just go ahead and download ROM Manager. Sometimes people forget there are *really easy* ways to do stuffs.

While I agree there are "really easy" ways to do things, I was trying to point him in the direction of learning.
Obviously since they don't know how to flash a recovery, they probably aren't familiar with much else.
Learning how to do things properly never hurt anyone.

El Daddy is correct.
Toolkits are silly on Nexus devices, for Nexus the simplest way is flashing via faboot. At the very least take the time to learn from the guide that El Daddy provided a link to. With that knowledge you'll be able to resolve issues like this and help others who get stuck.
Actually I unlocked my bootloader, rooted the device. Using normal OTA 4.2.1
But it seems that every toolkit cannot flash the recovery.
I will try it now with using adb commands...
All the toolkits are are scripts that run the fastboot and adb commands for you, they're nothing complicated and IMO from someone with experience I prefer using them now as I no longer have the sdk installed. Gave up on custom ROMs, my own and others, a long time ago.

Actually it's fastboot not adb that you use to flash recoveries, two different animals. and to the poster recommending ROM Manager, its kind of borked right now and I wouldn't use it to flash anything.
Edit: spoke too soon on ROM Manager looks like Koush updated it and it appears to be working properly. This was the first app I ever bought back in 2010 when I first rooted my Eris and couldn't get clockworkmod recovery to install, the moderators at the time recommended ROM Manager to me to get it installed as nothing else worked.
Yeah, but both didn't work.
I used now the adb commands on my one, still remembering them from my Nexus One, and see it works
For sure fastboot and adb will work. I used it very recently when my n4 updated. Just make sure to download the latest cwm. Had a boot loop the first time as I used an old one. Hehehe
Edit: actually not sure if it was the old fastboot files or cwm that caused the error. Anyway I updated my sdk so everything works well

Actually all the tools booted the phone fine in the fastboot mode, telling me flashing the recovery is fine.
But every time i wanted to reboot in the recovery i got this android roboter with the red alarm...
with the normal adb commands everything was really fine!
You're getting that because flashing custom recovery alone without modifying a file or two generates stock recovery every after a reboot. Go to your /system folder and look for recovery-from-boot.p and rename that to whatever you like then flash the custom recovery again

Can u access bootloader?
Yes if you can get into bootloader I suggest pushing the images back over to your phone. There is a restore to stock thread in development that you should look at

[q] help please

Well this is embarrassing to say what I actually did to my phone but I desperately need help to fix it (if it is possible).
My device is D802.
I wanted to try some custom rom so I installed TWRP 2.6.3.2.
I have downloaded a rom and gapps and then I saw that it is desirable to wipe everything, and I mistakenly wiped even data on internal storage which left me without rom to flash.
I can enter recovery and download mode, but it can't seem to start that offline flash tutorial I found on this forum.
I am on Windows 8.1 and tried to install drivers. I did not get any errors during that but adb do not see my phone. when in recovery. PLEASE I am desperate, someone help me! (maybe I just said the stupid thing but I am not that good in all of this).

Thank you My problem was that adb did not "see" the phone. I had to manually install the driver. Once I got that working I managed to install a custom 4.2.2 RM. Do you have any idea why I coud not install 4.4 rom (I get error no matter what version I choose).
But seriously thank you very much for the efort of replaying and pointing me to the right direction.
You need a newer version of your recovery to install kitkat roms
