I have been trying to flash TWRP and CWM on Nexus 7 which would not bootup (similar to sleep of death but when I erased data using fastboot it works) but now after unlocking bootloader I can't flash recovery.
In therminal I get "invalid status" after I execute the comand ...............................
Any ideas?
I would sincerely appreciate all your help!
To be more specific
This is what I get in terminal

My N7 "2012" kept freezing, so I put it in bootloader and tried to do a recovery mode reset to stock. It froze during the process.
Now, the only thing I can do is get it into bootloader mode manually by holding the buttons. It frezes if I choose any of the options from the bootloader screen including restarting the bootloader from the bootloader screen without holding power and volume.
I have tried the Nexus Root Toolkit a bunch of times with the "flash stock + unroot (soft bricked)" feature, testing different factory builds and the best results are below:

PLEASE HELP! Keep in mind that I am a newb to messing with this stuff.
I have read forums and tried things that people suggested to others in similar situations, but I am pretty lost at this point. Keep in mind that my device is almost certainly wiped and definitely will not boot the OS.
Is your N7 the Wi-Fi or the 3G variant?
What was the name of the factory image you were trying to flash?

After doing a bit of research, I've found out that there is a BAD version of the N7 2012 bootloader 4.23 floating around. The unsettling thing is that it's being supplied with a couple of the factory images that come straight from from the Google android devolpers page online. Anyway to make a long story short, I would try flashing the working version of the bootloader first off, then go from there with a factory reset. You can download the the working bootloader (bootloader-grouper-4.23.img) HERE --> h t t p : / / g o o . g l / q A D S A z (sorry about the spaces in the url, I'm new to the forum and can't post links yet, just delete the spaces)
BTW, its the same bootloader for N7 wifi OR 3G. md5 = df53028033c9eccf4fe5ba7bc198ce24
Here's how to install using fastboot:
1. Reboot To Your Bootloader On You Nexus 7 (Power off power button and volume down until you see bootloader screen)
2. Connect Your Nexus 7 To Your Computer
3. Open Up Command Prompt or terminal window (not sure if you are using windows/mac/linux)
4. CD to where you downloaded bootloader-grouper-4.23.img
5. Then type:
fastboot devices (to see if your N7 is connected correctly)
fastboot flash bootloader bootloader-grouper-4.23.img
fastboot reboot-bootloader
Then try the factory reset again.
If you don't have fastboot installed your computer you need it. Makes flashing your N7 a breeze... lock/unlock, custom recovery installs, going back to factory stock, all much more easy with fastboot.
You can get it from the android devolper site, h t t p : / / g o o . g l / 2 q p r for windows/mac/linux. All you need is the SDK tools, not the ADT bundle.

Wi-Fi
I have tried every one that the NRT offered.
Just read this guide and download the latest factory image from here.
Good luck.

I read that guide.
But that guide seems to be written with the assumption that the device can boot into the OS
No ADB device is found because I can only boot into bootloader.
That part is only for the driver installation. You can skip to the "Extract the Factory Image" part and follow it from there.

The Nexus was frozen at this point and had to be manually forced to restart bootloader.
Do you have a valid warranty for the N7? I'm asking because it seems that your N7's internal memory got corrupted. I might not be right, but that's my best guess.

I bought it 13 months ago (perfect timing, coincidentally, right?), so if I could find the receipt I would still be screwed.
I would still try to send it to Asus or Google. Maybe they repair it for a reasonable price.
(But if you plan to do that try to relock you bootloader with fastboot oem lock)

But then the N7 freezes and after manually restarting in bootloader it is still unlocked.
Then send is as it is. You can't do any more about it.

same with me ?
Try to relock and then unlock. I've had this problem too after downgrade to mm by official Huawei rollback package. Then phone and other tools shows than phone is unlocked and it was unable to flash recovery.
if it says wrong password it means you got the wrong password. it will say it's already unlocked if you try unlocking it while it's unlocked
My phone was unlocked with Potato v2.0.1, with working TWRP, rooted etc...
I solved this problem that arose after unsuccesfully install custom Rom, restore backup of stock rom, install update through dload and many many other attempts at improvement of my smartphone :-( No more time again!!!
Probably installing update through Dload will relock bootloader, but in the fastboot mode it says bootloader still unlocked.
Before I did all this, I had an original stock rom.
1: Relock bootloader with PotatoNV v2.0.1 (You need to open case and connect tespoint by wire - look on Youtube, i´ve find it there, also you need "Huawei testpoint drivers")
2: Factory reset
3: Install any update stock rom with Dload (Vol up + Vol down + power)
4: Factory reset
5: Developer options-turn on OEM unlock and USB debbuging
6:Unlock bootloader with PotatoNV v2.0.1 - keep password generated by Potato
7:Multitool 8 for Huawei - in the bootloader state unlock bootloader again - use password generated by Potato
8:Multitool 8 for huawei - install TWRP - it says "Succesfully installed" - TWRP works, root is possible. Yeah!!!
May be this is not right way to solve this, but for me it workś..

I don't know if you installed a custom Rom or not, but install the stock Huawei recovery. Than in a microSD card put the stock ROM. Than press vol up+voldown+lockscreenbutton.

I tried to install Elite ROM v7.7 for P10 Lite via TWRP using the zip file. It installed with some errors but after rebooting the phone does not come on at all. Screen is black. but I do have fastboot access. I've tried using the factory ROM in the dload folder but when I hold in the buttons it just makes the USB connect/disconnect sound in windows as if you plug or unplug a usb device, screen stays black. I'm starting to lose all hope now. I just payed a lot of money for this phone only to brick it...
