[Q] Re-instal OS in Nexus 7 - Nexus 7 Q&A, Help & Troubleshooting

Well, i made the mistake to delete the OS when trying install another rom, and now, I can´t connect my Nexus 7 to the PC.
I have tried pushing the zip file to my storage via adb and fastboot, but it says that there are no devices attached.
How can I solve this?
Thanks in advance
(I´m using TWRP 2.6.3, I don´t know if that´s important..)

Boot into recovery, then try ADB push or sideload.

*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

Nexus 7 - No Android installed, outdated recovery, fastboot not working

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.

[Q] Stuck at recovery!!! Please Help!

Today, I have tried updated my Nexus 4 to cm-11-20131205-SNAPSHOT-M1-mako.zip, but it apparently could not be flashed, so it ended up failing. Now, whenever I reboot my phone, it just ends up on my TWRP recovery screen. Please help me solve this urgent problem!!!
Sideload another ROM through adb
Sent from my Nexus 4 using Tapatalk
are you using the latest TWRP? what version it is?
Sent from my Nexus 4 using XDA Premium 4 mobile app
Well, what about wipe everything If can access recovery and then flash new image.
If you have custom build.prop you should adb push it with your default version of it, i had the same problem today.
Could someone teach me the steps to use the ADB sideload that you guys are talking about? Sorry, I'm not that tech savvy, and need some help :/. Does the ADB require the device to connect to a computer? If it does that may be a problem because my device doesn't appear when I connect it to a computer. On a sidenote, I have yet to update my TWRP, it's still v 2.4.1.0.

TWRP no OS detected HELP!!!

I just installed TWRP on my N4 and have never used it before. I always used CWM and I just wiped it through recovery. My issue is that I wiped EVERYTHING. It says "no OS detected" and won't boot past the Google logo. Can't install drivers when connected to the computer, and I can't for the life of me figure out how to flash a stock image, or fix it with the nexus root toolkit. Could someone PLEASE give me a walkthrough for a noob of how to go about fixing this? I don't understand a lot that deals with ADB and all that. Thank you.

Google tool adb fastboot drivers. Then Google nexus 4 factory image and download that. Use 7-zip to extract it. Flash the flash-all.bat while your phone is in fastboot mode and connected to your pc

Do I she the factory image it originally had which was 4.2.2 or do I use the image I updated to which was 4.3? Don't know if it matters, but I've never done this so I don't want to make anything worse.

If you don't understand, this time right now seems a good reason to learn about it right?
As to you problem, can you boot into recovery..the twrp? If yes, then it is easy. Just sideload a rom (preferably a 4.2.2 rom as it was the last rom on your device). Oh and yeah, sideload does use a bit of adb command (see how important it is for us, the nexus user?).
The other way is to simply use toolkits (which is a shortcut, not good as you will learn nothing of the whole process and it just takes all the fun away). Look in original android dev section for wugfresh toolkits (but I really, really, really hope that you learn ADB. After all, we need to learn to count before we start using a calculator right? ). Good luck. Don't sweat it so much.
p/s: That video there can be used for any android version and any rom of nexus 4.
Sounds easy enough. My only issue has been that I couldn't install any drivers. I can boot into twrp, but that's it. Any guide I've researched says to turn on USB debugging, which I can't figure out how to do since it won't boot past the Google logo, and the drivers won't install correctly when I connect the nexus to a computer.

Use wugfresh nexus root tool kit to flash a stock rom.
USB debugging is not required to flash a stock ROM via fastboot.

The easiest in my opinion would be sideloading a new rom, like cm11, paranoidandroid etc. Then you could easily install it on your n4
See here how to do it: http://teamw.in/ADBSideload , http://forum.xda-developers.com/showthread.php?t=2559200 , http://forum.xda-developers.com/showpost.php?p=45798359&postcount=825
Tried the toolkit yesterday. Didn't work because it couldn't install the drivers
Sent from my Z665C using xda app-developers app
Install drivers manually. Just Google "nexus 4 USB drivers" download and install. Then get toolkit and flash stock image.
Sent from my Nexus 4 using xda app-developers app
I'll try again. I was able to figure the drivers out. Tried flashing a stock image I downloaded, but I still wouldn't boot past the Google logo. I flashed it to the system partition, but I didn't know what partition to flash it to. Do I need to use the modified boot image it wants me to download, or am I supposed to flash it to a certain partition?
Sent from my Z665C using xda app-developers app
FIXED IT!!! thank you all for your help.
For anyone else with this problem, I downloaded "universal naked drivers" and installed them manually, use the Nexus Root Toolkit selected "soft brick, than flash stock/unroot, let it download RETORT and the modified boot image, flash it in fast-food, then when it booted up, re-rooted. (You lose root access when you do this).

[Q] I wiped it! Can't find Rom/GAPPS.

I already had paranoid Android installed on nexus 4. I checked every folder, still can't find it. Anybody know where it should be?
Thanks for your help!
Did you download it directly in your phone?
--------------------------------------------------------------------
NEXUS 4
Version: 4.4.4 (KTU84P)
ROM: PA(4.5BETA-1)
From what I'm reading, you don't have a booting ROM and don't have the zip on your internal storage. You can download the PA zip onto your computer and adb sideload it in recovery (at least with TWRP).
