[Q] Nexus 7(2012) Recovery Mode no command?

Not really sure what happened, a while ago I had an issue with a game and restored my tablet back to factory settings to fix it, but now I discover that while trying to boot into recovery mode it's not there?
I'm trying to manually install the Android 4.4 Kitkat update, got sick of waiting for the OTA since I haven't gotten it yet and really want to use 4.4, but while trying to go into recovery mode to check everything is working because I'm paranoid like that and while I was successful into booting to the bootloader, trying to go into recovery mode resulted in seeing the little android guy with the red triangle saying no command underneath it, so I'm assuming somehow my recovery is missing?
I then tried to flash stock recovery onto my tablet using the Nexus 7 Toolkit and it told me there was an error in flashing the files and that it was because my device's bootloader was locked.
All I want to do is update to Android 4.4, but how am I supposed to do that when I can't boot into recovery? I've followed all the right steps to do it, did I do something wrong by locking my bootloader and unrooting my device?

Hi, JohnathanKatz...
Unrooting isn't the issue... it's locking the bootloader that's the problem.
If the bootloader of your device is locked, you won't be able to flash anything.
I don't use toolkits myself, but it's pretty straightforward to flash a recovery (stock or custom) using the fastboot tool...
* Unlock the bootloader with fastboot oem unlock
* Fastboot flash the recovery with fastboot flash recovery recovery.img
(...where 'recovery.img' is the name of the recovery image file to be fastboot flashed.)
Maybe there is an option in your toolkit that will unlock the bootloader again... however you do it (toolkit or fastboot), you MUST have an unlocked bootloader before you can flash a recovery.
Rgrds,
Ged.

Hi guys, I actually encountered this problem a minute ago when I attempt to flash a new version of TWRP recovery on my grouper. Whenever I go to the recovery, it just shows 'No command' with a red alert of Android on it (I started to panic when I found that there's an unusual error that prevents me from entering the recovery and this is the first time that I saw this error on my flashaholic experience *btw my previous recovery was CWM) I'm currently on stock 4.4.2 with an unlocked bootloader. I have no idea what problem is causing to display that issue when attempting to enter recovery but then I left it for like 5-10mins while it's displaying that error and after that the device reboots then it just quickly enter TWRP recovery normally as is :silly: sick of that haha, silly ol grouper jesus -_-
EDIT
After entering recovery, I got stuck forever on bootloader and recovery! whenever I reboot, I always get directly enter to the recovery and it forces me to not to enter the ROM oh my god at least I can still configure the recovery so I can backup and flash another ROM :|

Can anyone help me fix my Axon 7.

I tried to unlock my phone (A2017G) and flash lineage OS today following Controllerboys guide, but must have done something wrong, I managed to unlock it and flash the bootstack, but I hit an error when trying to flash LOS and so decided to reboot the system and try again, however when rebooting the system I got the error "Your device software can't be checked for corruption, Please lock the bootloader". And I cant seem to access TWRP anymore just the stock recovery.
Is there a way that I can just flash stock OS and be able to use my phone?

That's not an error message, it's the unlocked bootlaoder screen. get used to it, you're gonna see it every time you reboot
You probably didn't flash the Universal Bootloader. You didn't even read. You should install TWRP again with axon7tool, then get there and flash the Universal Bootloader, then the A2017G modem, the the ROM. If that doesn't work just download MiFlash and the latest G package and flash it

Unable to flash TWRP on Moto e3 power with latest software update

I'm trying to flash TWRP (twrp-3.2.1-0-taido.img) on my Moto E3 Power. I had successfully rooted this phone once, and that's why the phone is unlocked. So when I try to flash custom recovery using the command "sudo fastboot flash recovery twrp-3.2.1-0-taido.img", it says it completed successfully, but instead of booting into twrp, my phone is starting up completely. When I tried booting up custom recovery using "sudo fastboot boot twrp-3.2.1-0-taido.img", the same thing happened again.
The software on my phone is "23.0.XT1706_S151_180706_ROW". So far I've been unable to flash twrp on this phone, but I got it to work an year ago. Please, can anyone help me what's going wrong here? I'm following the tips on xda-forums using which other users were able to flash the same recovery on their phones.

you can try this

I think i really messed up

So here is what happened. I decided to take a crack at twrp and rooting my essential phone. its fully updated to aprils patch
unlocked my bootloader. HOWEVER i never used the command fastboot flashing unlock_critical. how ever it still said my boot loaders unlocked.
installed twrp no issue (other then touch but i figured that out) installed elementalx kernal. made a backup in twrp just in case.
booted into android fine no problems. found out my wifi does not work. ok now im just giving up. found out flashing the boot img will fix it. well i flashed it via twrp and when it asked where i said to the boot.
now my phone boot loops. i cant get into twrp. only a default recovery mode for android. i can get into the boot loader but im scared because ADB cant find my device anymore. trying to wipe deivce makes it reboot and boot loop again.
am i screwed? i dont care about the data but its 3am and i think i really messed up my phone

Are you still bootloader unlocked?? Can flash files via fastboot? If you can run the command "fastboot flashing unlock_critical" and then flash bts from this thread https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681

Installing angler image failed

Hello, I tried to install an os image on the Nexus 6P Android. In addition I downloaded the Angler Image where the flash-all batch is. I'm afraid that the files will not be transferred to the phone at all. For example, if I try to install TWRP in the bootloader and then reboot the phone, I am stuck with the Google logo and with the warning "Your device software can not be checked for corruption cant open bootloader" (Which is quite normal if you have unlocked the bootloader).
I'm not so good with it and hope someone can help me with it.
Please don't blame me if it is obvious. I'm a ****ing noobie

From your description I'm not sure exactly what you did. Did you fastboot flash the factory image? Did you fastboot flash TWRP? You need to do it that way if you didn't. See this guide...
https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928

So im using flashboot flash recovery twrp.img and after that i reboot the phone and im getting the same problem that im stuck on the warning message.

after flashing the factory image
let phone boot up into system for a minute
boot into your bootloader
boot into your bootloader using fastboot the twrp.img
once in twrp, flash the TWRP.ZIP file on you sdcard
then you can install cust kernel or magisk, or just reboot to system
