Hey, i was trying to downgrade my phone but insted of this i think i messed it up really badly.
Exact things i did:
I used adb (adb reboot bootloader, fastboot boot stockboot.img)
and after reboot this error appeared.
I have no root on my phone. So i have stock recovery mode.
Please any magical help?
I can get into fastboot mode and android recovery, even twrp but i cant copy files from computer.

Hi there,
i bought a used nexus 7 (2012/1st gen) which only boots into recovery (cwm v6.0.2.3) but doesn't show the menu. Only the cwm logo in the center and the version at the bottom left. (see picture attached)
I can't boot into fastboot (Vol Down+Power). This only leads to recovery again. But as mentioned above there's no content, no menu.
The previous owner told me he tried to flash Cyanogenmod 11 which failed and since then it is stuck in this behaviour.
I'm on ubuntu 14.04 and installed android-tools-fastboot and android-tools-adb.
With adb i can get a shell on the device in recovery mode but don't know what to do from there.
"adb reboot bootloader" doesn't work, the device is not responding
Can anyone help or am i doomed?
Update: I downloaded latest TWPR for "grouper" (2.7.1.1) and tried
" adb shell flash_image recovery openrecovery-twrp-2.7.1.1-grouper.img "
which lead to
" failed with error: -1 "
on step futher...
Update:
I was able to get into the bootloader with this method:

Now i am trying to flash the stock rom of the nexus 7 (https://developers.google.com/android/nexus/images?hl=de)
But i am not able to flash the bootloader. The version now is 4.18 and i can neither downgrade or upgrade. fastboot always gives me an error and won't proceed since it would need the bootloader to be 4.23
any help?
Flashing the stock image didn't work as expected.
Bootloader not working anymore
The device is now stuck at the google splash screen with the little open lock below.
I can't enter fastboot anymore, Power+Vol Down kicks me straight to the screen mentioned above...
The device is not recognized by adb or fastboot anymore...
Any hints how i should proceed?
I rooted my g2 and flashed the wrong ROM that I downloaded. Now my phone is stuck in fastboot mode and not showing in windows 7 device manager as "qhsusb" mode. It won't go into download mode either. I was successful using the fastboot cmd commands to delete the BOOT, ABOOT, RECOVERY, and LAF partitions but I am getting an 'error: cannot load 'boot.img' message when trying to load the new partitions. And so I sit here stuck wondering what to do next. I have the new .img files in the 'adb' folder on the root of my C: drive. What am I doing wrong?
Try flashing twrp, boot into twrp, flash rom from usb otg.
OK so phone was rooted with twrp installed. decided to update to latest ota 30b only I wiped and just flashed boot file and supersu without the actual rom. I know. now the phone goes straight into fastboot mode... I would think twrp is still installed but dont seem to be able to boot into it. I had adb and fastboot on my pc from before but havent used this in some time. if I try to open either of these the command window pops up and quickly closes.. What can I do ?.
new info: fadtboot is working in fact i have wrote a twrp recovery but still cant boot out of fastboot... adb device not listed. i reinstalled minimal adb and fastboot. help
I was on oxygen 3.0.2, so i decided to root my phone, first of all i unlocked my bootloader, but after the install of the root zip file, i got stuck in a bootloop, no way out i can't sideload or mount storage, i can access to recovery and fastboot so.. if u may help me to flash any another rom or just turn back to stock i'll be glad!
recovery: ok
fastboot: ok
no adb
bootloop
EDIT:
when the device is off, with command "adb devices" says:
<serialnumber> unauthorized
tried qualcomm usb mode?
I'm afraid I ****ed something up.
My phone bootloops and the only way to reboot correctly is to do "fastboot boot boot.img" with the STOCK boot.img (which can be found here : https://drive.google.com/drive/u/0/folders/0B7F3ZXr565GkUU5iYjJtLXE2STQ)
Also I am not able to flash anything on the phone.
TWRP says "Error executing updater binary in zip...", and when I attempt to flash something through ADB Sideload, i get "Cannot read zip".
How can I fix everything? I guess I flashed something wrong trough fastboot but I'm not even sure what.
Also I found out that my bootloader was still locked.
But I can't unlock it since I am on Lollipop and the ASUS Unlock Tool is for Android M (I get error when i install the apk).
So I would flash Android M to unlock bootloader but hey, I can't flash anything....
I kinda fixed it, atleast I can now boot normally.
I followed this tutorial by @MiauLightouch : https://forum.xda-developers.com/showpost.php?p=66364620&postcount=8
And now I can boot without using fastboot.
Still unable to flash stuff using TWRP though.
