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 :|
so i feel like Ive tried everything.
tried to flash a rom and gapps in twrp and phone booted to warning screen with the yellow triangle.
passes that and then goes to google splash screen with unlock icon. and then repeats to the cycle.
i have tried multiple 6.x.x builds using skipsoft toolkit with no change.
i have installed twrp and tried to flash 6.x.x rom and 7.0.0 rom.
i have tried to flash stock NBD90X 7.0.0 using nexus root toolkit.
i have tried going into stock recovery and wipe data/factory reset
i have tried minimal ABD fastboot and running the commands manually.
All have failed to change the boot looping i experience.
my phone is unlocked.
computer can see it as fastboot devices
computer CANNOT see it under abd devices
i am able to install and get into TWRP using skipsoft tookkit.
i feel like i am running out of things to flash onto the device haha
any help is appreciated.

First, I'd recommend staying away from Toolkits, as you can't really see what's happening and diagnose issues. Since you've used fastboot/ADB commands, you know they are faster anyway. When you say your PC can't recognize your device in ADB, was your device in recovery? Make sure you're in recovery and you're ready to receive ADB commands. If you CAN see your phone with fastboot that means you're in the bootloader, whereas you have to boot into recovery to see your device via ADB.
Also, you didn't outline anything else you may have done. Did you restore from a nandroid with a buggy version of TWRP? Your issue sounds like the TWRP EFS restore bug (3.0.2-2). It effectively bricks your device, but there is a thread here that discusses it. Effectively you need to be recovery ADB mode and run a couple commands to delete your EFS partition and that will fix the issue.
More info here: http://forum.xda-developers.com/nexus-6p/help/im-stuck-google-logo-stop-reboots-twrp-t3452842
Make sure you've also installed the updated 3.0.2-3 TWRP as it will work with encrypted data and doesn't have the EFS bug.
New to XDA so sorry if i posted this in the wrong place
But recently i received a new phone, an LG Stylo 2 Boost Mobile. It recognized fine while it was on through adb, but when i turned it off and booted into recovery, it wouldn't be recognized by adb, nor fastboot, and when i tried to "reboot into bootloader" it only restarted the whole phone into its normal boot. Adb sideload worked but i had no idea what files to try due to a locked bootloader and no stock ROMs found anywhere. I tried kingroot and it didn't have any ways to get an instant root. Im running Ubuntu and the phone is on 6.0.1 Marshmallow. Any ideas out there? I'd be sure to give them a try
The phone would only be accessible in recovery via the adb sideload option with stock recovery.
What exactly are you trying to accomplish?

I'm trying to unlock the bootloader so i can flash a new recovery then root won't be hard to achieve, but when i try to access the phone in recovery mode, it doesn't recognize whatsoever. I thought there would be something i could do with sideload to somewhat downgrade the system and gain some type of bootloader, but that didn't work. Is there someway i can flash a custom recovery?
Don't believe there are any options for unlocking the bootloader or a custom recovery for that phone. According to what I could find in a quick search, there is root available but only on the software update ending in ZV3.

Alright, thanks for the info, wasn't sure if there was a way around it or not
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

hey hope all is well im sorry for the late reply. i was able to figure everything out i flash the wrong boot.img and twrp its not perm on my device. I saw a threat that lets you go back to stock and has aprils build. thanks for your help tho!!!!!
my nexus 6p is not booting into rom, recovery (stock and custom).
i have a unlocked bootloader, flashed custom recovery(twrp) by fastboot but can't get in to twrp as i wanted to flash blod patch to use 4cores to work.
i tried flashing stock images of MM, Nougat, Oreo using platform tools by google but getting an error like see in the attachment:crying:.
i tried it with fastboot by manually entering commands it will flash but not use still bootlooping.
i tried toolkits like NRT & all in one toolkit by XDA member this toolkits can flash stock rom successfully but cant get boot into system, stock recovery.
help me with your answers. my status is "unlocked bootloader, fastboot working, can access bootloader but can't get into recovery from it".
getting couldn't parse partition size 0x when booting boot img through platform tools.
tell me if i did any mistake. Thank you.
You tried stock images. Does that include factory images? That erases and reflashes quite literally everything (bootloader, recovery, system, etc.)
Find them here for 6P: https://developers.google.com/android/images#angler

You didn't mention which custom recovery you flashed. Did you try the one in this thread? https://forum.xda-developers.com/t/...-death-blod-workaround-flashable-zip.3819515/
If you did and you still can't get into it, your device is likely dead from the BLOD. But to make sure you have the BLOD, flash the latest factory image first (Dec. 2018) with the latest platform tools to see if it boots... https://developer.android.com/studio/releases/platform-tools

firstly i already cant boot into stock recovery from my bootloader i'm on stock os 8.1.
and now i've flashed twrp for angler from twrp website but cant boot into custom recovery too.
now i've flashed twrp image of 4cores but still can't get into recovery.
so what's the problem of this phone if my mobile cant get even into twrp i can't do blod patch if we think my device is suffering from blod issue.
do you think it may be the problem of hardware like ram,emmc, or the SD 810?

As I said in my previous post, if you can't boot into the 4core custom recovery, your device is likely dead because of the BLOD, unfortunately. If you are on stock with nothing else on your phone that might be preventing you from booting (e.g. mods, Substratum overlays, etc.) there's not much else you can do.
Is your device recognized in fastboot?

Hi, I am havin same problem as the user above....I am on stock 7.1.2 right now. Unable to boot into TWRP, i flashed twrp-3.2.1-0-fbe-4core-angler.img and then entered recovery from bootloader screen. nothing! i also tried to do a temporary boot to my recovery via fastboot command. didn't work! I dont think my phone is that dead...but I don't see why it isnt booting into twrp...i did the flash all of stock firmware from the Google website. Any assistance? Currently I have a Pixel 2 thats not working, so i thought I would try to revive the 6P, but no luck so far.

thanks but no assistance required as i have sold it to another nexus 6p user for using it's spare parts.
