[Q] help, no rom in my nexus 7

I Did something really stupid, I have a Nexus 7, rooted, unlocked, went to twrp and did a back up of the stock rom, it said successful, then rebooted used the rom, everything perfect but I had tablet mod on it, decided to go back to full stock, booted to recovery, wiped everything, tried to restore and my backup is not there, and I deleted the rom as well, so now I have no rom to flash and I'm stock in recovery, anyway to push a rom into the nexus in recovery or bootloader? I tried flashing it with root toolkit 1.5.5 but it doesn't find the tablet,(all the drivers are installed), any and all help is appreciated...

Your PC won't see your N7 in Android because you haven't turned on USB debugging, and probably can't now.
You should be able to push an updated TWRP in fastboot that will see your 4.2 backup. The older version can't find its backups in 4.2,as you've discovered.
I'm not the lowest of the low, but I am the slowest of the slow.

I did have it on, I can see the tablet from control panel, but when I run the kit it says adb device not found..

The drivers will let your PC see the N7, but you have to be in USB debugging for ADB to work. You lost it when you wiped your system, as the failure of the toolkit to see the ADB proves.

USB Debugging doesn't need to be on for ADB through recovery to work.. Why would it? The system isn't even on it is in recovery.
Try the toolkit in fastboot.

when I'm in the bootloader it says it's in fastboot mode, but the toolkit wont find it!
I running recovery 2.3.2.1
tried adb sideload as well and it says "cannot read sideload" any ideas? getting a little crazy here..

Can anybody give me specific commands in ADB or fast boot I'm an idiot when it comes to that, on how to try to push a ROM into the device so I can flash it from recovery, or maybe a link to where I can read about it, I would really appreciate it..

While in recovery, type in the following:
Code:
adb push <name of ROM zip> /sdcard
You need to open a command prompt window, change directories (cd) to your Android SDK - platform tools directory, and to make things easy, move the ROM zip file into that directory as well (platform-tools that is). Then type the adb push command above.
EDIT: This puts the ROM zip on the root of your sd card (/sdcard). I have a ROM folder on my sd card, so I would type:
Code:
adb push <name of ROM zip> /sdcard/ROM
This just shows that you can push a file into a folder on your sd card.

[Q]Manually updated to 4.2.2... Now locked out of adb and recovery. Help.

I'm in a bit of jam. I flashed the official zip from google to update to 4.2.2 and the flash seemed to work fine. I cleared both caches after the update
However, now I seem to be completely locked out of adb and the phone doesn't prompt me for authorization (the new feature in 4.2.2) http://www.androidpolice.com/2013/0...s-from-stealing-your-data-in-some-situations/ . I am showing connected but offline just like this article. I have tried multiple reboots (phone/computer) as well as different USB ports. I have not tried another computer yet.
When I try to go to recovery I get a red exclamation point dead robot as I assume the flash wiped TWRP and I can't reflash TWRP without adb/root.
I would like to try to avoid a complete internal memory factory reset from the rom which I'm not sure would work anyway.
Please help.

update your adb / sdk.

Fortunately, I was able to reflash TWRP using fastboot w/o using adb. At the bootloader, I ran
Code:
fastboot flash recovery recovery.img
which got my recovery back up and running.
I decided to do a factory wipe and even after that adb was showing as offline and not prompting. I am very confident that your suggestion of updating the platform tools is going to fix my issue.
Thank you.

Locked on 4.2.2
My Nexus 7 is locked on 4.2.2. I tried to Unlock with Nexus Root Toolkit and I get "adb offline". I did the command "adb devices" and the device showed up, but when I tried to unlock again, it gets stuck on "checking adb status". I updated SDK and copied the new adb.exe, fastboot.exe, etc into the platform-tools folder and it still doesnt work. So basically my oem is locked on 4.2.2 and I can get adb or the toolkit to work properly.. Is there a way to downgrade back to 4.2.1 or get the Wugfresh Nexus Toolkit to actually unlock my Nexus 7 on 4.2.2??

Yea, there's a way to downgrade if you have a nandroid and know what you're doing. The toolkit will need to be updated, and it helps to know how to do it manually first.

If you know the steps or can link me to a page, that would be much appreciated. I want clear steps.

Basically the same thing just happened to me. I updated to the newest android sdk then followed the steps here http://forum.xda-developers.com/showthread.php?t=2010312
I had to restore the complete stock image first, then I sideloaded the update. I made sure all of my files were in C:\Development\sdk\platform-tools (thats the directory I used, yours may be different). Open a command prompt on the platform-tools folder and run fastboot devices, if you see a number there you are good to go. Just follow the steps in the link above to flash each file.

Why cant people wait..

I'm going to try this. Can i just type "fastboot devices" in the command prompt and it'll work?
EDIT: I found a simple fix for anyone with this problem: CREATE A BACKUP FIRST, THIS WILL ERASE EVERY THING
1. Go into the platform-tools and open the command prompt by pressing Shift + Right Click.
2. Type in "adb reboot bootloader"
3. Then type in "fastboot oem unlock"
4. WALA! It'll take a while to start up, don't worry. Set up your device and that's all.

But with oem unlock, you'll still be on 4.2.2. This thread should offer good info on flashing, albeit for a galaxy nexus, but it should be mostly applicable for a nexus 7. http://forum.xda-developers.com/showthread.php?t=1626895

That's the point; we want to be unlocked and rooted on 4.2.2. I previously thought that in order to get an unlocked and rooted Nexus, I'd have to be on 4.2.1, unlock and root, then upgrade to 4.2.2 but that's not the case. I just unlocked and rooted via ADB since the Nexus Root Toolkit wasn't working for 4.2.2. I (and probably others) kept getting the "adb offline" error even after allowing USB debugging between the device and PC. Point is, if you're on 4.2.2 with a locked bootloader, you'll need to unlock and root using ADB commands. I don't know how many people have this issue but if someone requests it, I'll just post the steps on how to unlock and root 4.2.2 jelly bean using the ADB commands.

Re: [Q]Manually updated to 4.2.2... Now locked out of adb and recovery. Help
What if I'm on 4.2.2 completely stock but with an unlocked boot loader. I get the adb offline message when I try to root using a toolkit. How would I go about rooting?

Place su.zip on sdcard. Reboot in fastboot mode, probably volume up+down+power. In terminal on pc, fastboot boot cwm.img for your device, install zip from sdcard.

1. Download the SuperSU.zip from here: http://download.chainfire.eu/282/SuperSU/CWM-SuperSU-v0.98.zip and place it on your device in the sdcard. I'm assuming you already enabled USB debugging.
2. Download the recovery-clockwork-touch-6.0.1.0-grouper.img from here: https://www.dropbox.com/s/v4hjsb4lse3dwtc/cwm6010touch_INSTALL.zip and place it in the platform-tools folder. Assuming you know where it's located on your PC
3. Locate the "platform-tools" folder on your PC, open it, and press Shift + Right Click & Open the command prompt there.
4. Type in the command "Adb reboot bootloader"
5. Then type in the command "fastboot flash recovery recovery-clockwork-touch-6.0.1.0-grouper.img"
6. Now go to Recovery Mode on your Nexus and install the CWM-SuperSU-v0.98.zip from there.
7. Reboot the device once you're done and you have a rooted Nexus 7 via adb. Hope this helps.

This worked for me. If your recovery, (CWM or TWRP), still works fine, then it's a simple fix.
Download the software developer kit from google if you don't have it already.
Put your ROM and gapps in the platform-tools folder of the sdk package you downloaded and unzipped from google.
load up command prompt on your computer, and boot your phone into CWM or TWRP and find the option to sideload.
On computer, in command prompt navigate to the platform-tools folder wherever you unzipped the sdk from google, and use: adb sideload filename.zip for the rom and for your gapps.
you don't need to push files to the phone. just use sideload and install them to your phone right from your computer. the first time I made the same mistake as you I was terrified. but, it's a really simple fix.

Help. Unbootable N4

I accidently formatted my internal storage and system partision through TWRP recovery. Now im stuck with an unbootable Nexus 4 since there is no rom installed. How can i push a zip into my device? I can only access TWRP and Fastboot. and never really used ADB. I used a Toolkit to Root my phone (WugFresh's Toolkit) cant really use that since i cant boot my device to turn on USB Debugging. Any help?
Update: Searched several hours on xda, i cant manage to set up adb. Redownloaded Android SDK. Installed/updated adb (v). Tried multiple drivers (from official google usb drivers to univeral usb driver from Koush). Every time i open cmd and type "adb device" and long list of adb commands and other stuff appear. every time i type adb and any word infront of it, that happens. adb doesnt want to run or something. This is getting fustrating. and when i run adb.exe (from toolkit folder) it closes really quickly. only odd thing i see is under device manager my Nexus 4 is being displayed as Google Galaxy Nexus ADB Interface???

Hi the command is 'adb devices' if it's showing you the commands adb is set up correct. You don't actually need adb for this though, get your phone in fastboot mode and type 'fastboot devices' with your phone connected. If it outputs anything you're ready to flash a factory rom and fix your phone.

Nexus 4 (4.4.2) not mounting after unlocking bootloader

Nexus 4 running 4.4.2 bootloader version MAKOZ30d
I used Wug's root toolkit to unlock my bootloader but after reboot into fastboot, neither my windows 7 machine nor my linux mint machine will mount the phone without MTP turned on. I can run adb commands while MTP is on but drivers fail to load if mtp is off.. So now I have an unlocked bootloader and am unable to complete the rooting proces..
Any help is much appreciated.
Cheers!

go to settings/storage open 3dots menu /usb computer connection. if nothing is selected that is why your phone doesn't connect. select mtp an problem solved.
if it's not that i cannot help you except suggesting to reinstall android from scratch using wug toolkit.

Trying to finish the rooting process by using adb.. by "mount" I mean get access in fastboot from either of my computers.

It seems like the adb drivers aren't loading while in fastboot. I'll try to back things out using the toolkit again..

OK, so your fastboot commands are not working, that would likely be a driver issue? If you do
Code:
fastboot devices
and get a result, then keep going, if you don't, use one of the driver options in Wugfresh's toolkit, follow the instructions TO THE LETTER...
If you are just trying to get root and are unlocked, download the latest SuperSU.zip (to your phone preferably) from http://download.chainfire.eu/supersu and openrecovery-twrp-2.7.0.0-mako.img then start phone in Fastboot mode and enter:
Code:
fastboot boot openrecovery-twrp-2.7.0.0-mako.img
this will start TWRP on your device WITHOUT flashing it.
If the SuperSU zip file is on your phone, just use TWRP's Install button and navigate the file and flash it, then reboot and enjoy.
If the SuperSU zip is on your PC, then in TWRP go to Advanced, and start ADB Sideload, give it a few seconds for it to be recognized by your PC, you should be able to enter
Code:
adb devices
and get a result of SIDELOAD back, then enter:
Code:
adb sideload UPDATE-SuperSU-v1.94.zip
Or whatever the current SuperSU zip file is named. Then reboot and enjoy, your rooted!

Remember that adb commands only work in android and custom recovery NOT in fastboot mode.

ADB sideload is a special mode that recovery can be placed into, it only allows the "sideload" command to be used. Fastboot is different, it uses the fastboot.exe program and fastboot mode on the android device to allow a limited list of features to be used.
I don't know what you are using for a rooting guide, but basically the end result is to flash SuperSU via recovery, that is all that is really needed.

Well, basically if your boot loader is unlocked and you have a custom recovery installed just download the latest superSU zip to your SD card. Reboot into recovery, install SuperSU, reboot. Alas, you're rooted.

If you unlocked your bootloader your drivers should be working fine. If you rebooted your phone now you'd see it works fine. Next step in rooting is to flash custom recovery. Download a custom recovery, I recommend latest version of TWRP, then flash the recovery image. 'fastboot flash recovery recovery.img' (replace recovery.img with whatever .img file you are flashing.
Once custom recovery is installed you can boot into it to flash supersu. If using TWRP it will prompt you to root when you reboot it.

Thanks.. And please don't take offense to this but re-read the thread. Ever since I used wug's rootkit to unlock the bootloader, neither my pc nor linux machine will recognize the Nexus 4. When I plug it in I get a usb error "device failed to load".. When I look at the device mgr it's listed as unknown device. Btw.. I've restarted both my phone and machine multiple times to no avail.
