Nexus 2012 Omni ROM WiFi grouper.

I have a problem with my nexus 2012 WiFi version
I put twrp recovery 2.7.0.0 and omini ROM 4.4.2. Since then I have been unable to wipe anything on the device. I wipe or format in twrp when reboot every thing is same. Even with fastboot I format internal SD or wipe everything. It says it is OK but when u boot nothing is wiped. I can install apps but when I reboot they are erased and only apps which were there earlier stay. Please help. Another guy in the forum has same problem. I updated from slim ROM to omni and the problem started Now I can't even delete anything in twrp recovery or update twrp recovery in fastboot. It says its done but when I reboot to twrp its not updated.
Also in fastboot I can't lock boot loader by fastboot OEM lock . The command goes through in fastboot but when I reboot its still unlocked. Please any hep is appreciated from any one on XDA.
Default Can't wipe or factory reset Nexus 7 (2102) using multiple methods
A month or so ago my Nexus 7 (2012) started rebooting itself after a minute or so of turning on - I think this may have been during OTA upgrade from JWR66Y to new release. I tried to fix this by clearing app data and booting into CWM recovery and deleting cache and dalvik cache but the problem persisted. So I decided to reset the Nexus 7 back to factory image and have tried every means of doing so but every time I keep getting back to my original data and the app crashes and reboot continues. I have never had any issues connecting to the device on USB and ADB so this is not a driver issue. Things I have tried:
* Hard reset on phone from recovery (plus endless deleting of cache and dalvik)
* Hard reset using Wugfresh toolkit (plus near every other tool on there)
* Hard refresh from recovery mode
* Hard refresh using ADB and deleting user data etc.
* Flash recovery from ADB (also using Wugfresh as per above)
* ADB sideload from recovery of factory images, bootloaders and other ROM's
* Lock/unlock/root/unroot - using ADB commands as well as Wugfresh and other toolkits
* Delete data, system, cache
It seems like the Nexus 7 going into read only mode? Erasing /data and everything else in recovery has no effect and also when trying to overwrite the bootloader I get "writing 'bootloader'... FAILED (remote: (InvalidState))" using Wugfresh toolkit as per below. The device is still running JWR66Y.
I'm totally stuck now as to how I get my Nexus 7 back again! I have seen other people having issues with the JWR66Y bootloader (http://forum.xda-developers.com/show....php?t=1907796) but have tried all the workarounds and can't seem to find a way to overwrite the bootloader...

Booting up your freshly flashed stock device...
------------------------------------------------------------------
Wait for your device to finish booting up...
- It may appear to be boot looping; just wait...
- It could take 5-10 minutes; please be patient...
When its finally booted back up, please remember
to re-enable USB debugging if you plan on using
the toolkit to perform other operations.
Press any key to exit...
Any Help?

Use fastboot to flash the 5.1 images. Flash each individually and ensure you wipe data

still no go

Still stuck on Beanstalk 5.0 animation, recovery is still TWRP 2.8.3.1. I've tried to format to different formats (ie; fat, ext2, ext3) nothing is working

I have also tried using twrp to move over the .zip of the factory 5.1.1 and it just stops transferring about a 3rd of the way through.
I am fairly certain that i have the latest fastboot as well as all the latest from the sdk tools manager

It looks like a connection problem somewhere. Are you able to try a new cable or USB port?

If you have the SDK installed make sure it's updated or use mfastboot either one will work with the larger file sizes.

first try using fastboot flash recovery recovery.img
secondly, try using the flashify app to flash your recovery instead of using code.

No root, so it looks like no flashify.
I tried both fast boot with stock recovery.img and tried flashing Android M to see if I could go back.
At this point I can't get bootloader to change or install recovery partition.
Any help with the issue would be great, tried all the basics already but this seems to be beyond me as to why the recovery partition is no longer flashable.

When I flashed the 7.0 image I got that same error "(bootloader) has-slot:xxxxx: not found" for each image file I flashed with the corresponding image file name in the error message but everything still flashed successfully. I don't think that that error is a fatal error, or at least it wasn't in my case.

Yeah, I think I have to agree here. I did get TWRP flashed, I think my copy was corrupt and I pulled a good copy and flashed it and now I am solid, if only my backups weren't at work
Thanks for the helps people.

Glad you got it sorted out!

I will admit, I was a bit panicked and started to come to grips with the fact that I may need to just have stock on it... but nope, back to not so stock I go.

Its because of latest adb and fastboot, if u r flashing from computer. Use an old version of adb and fatboot, and u won't see these (boot loader) slot count not found, etc... Anyways flashing would be success

Your first posts states that you were trying to flash twrp-3.0.2-0-grouper.img
Grouper is Nexus 7 (2012). That might have been the problem. Nexus 6 code name is Shamu.

How could I recovery my Nexus 6

Hi,
I was trying to update my Nexus 6 to Android Nougat(nbd90z) today, the system image failed to be flashed. And then I locked the device by mistake. Then I became unable to flash any images.
If I tried to flash any image, it failed and the message is below.
(bootloader) Not allowed in LOCKED state!
FAILED (remote failure)
If I tried to unlock the device, it failed and the message is below.
(bootloader) Check 'Allow OEM Unlock' in Developer Options.
FAILED (remote failure)
And because the system image failed to flash, so I can't boot the device to check the 'Allow OEM Unlock'.
Is there any way to recovery my device? Thanks very much for the help.

Below is the text from the command terminal where I tried.

Flash an OTA image. They're intended to be flashed even on locked systems.

Thank you for the reply. Does flashing OTA images needs to boot system normally? My phone is unable to boot system normally due to failure of flashing system image.

Strephon Alkhalikoi, thank you very much. I got my device recovered.
I followed the instructions at https://developers.google.com/android/nexus/ota, except replacing Step 3 by below steps to boot into recovery mode.
a. Hold Volume Down key and press Power key to enter fastboot mode.
b. Press Volume Down key to navigate to "Recovery mode" and press Power key.

Do you have recovery installed?
If yes and hopefully TWRP which is best option, just go to recovery, mount phone, transfer OTA image, factory reset, and flash it.
Also, if upgrading from 6.x.x to 7.0.0 you must flash the Nougat bootloader img. which in order to do it, i recommand using Nexus toolkit which you could access only via phone being on.
So what i do recommand is the next thing:
download 6.x.x ota and install it.
boot into phone, unlock developer options and usb debugging, also check the "oem unlocking".
plug the phone to the pc while using an adb program like nexus tookit, unlock bootloader.
then download the Nougat bootloader img, and radio img (not a must). into the pc, and flash it via nexus root toolkit once again.
After your'e done flashing, all you have to do is go to recovery mode and flash the Nougat rom.
And before all that, make sure you have the latest TWRK recovery.
