So yesterday I went to flash a Kernel and needless to say it didn't work. So just like my Galaxy Nexus, I held down the special key combo and got into the Bootloader, scrolled to Boot Recovery and it went to the Google screen but never went to recovery. I figured it just froze so rebooted into Bootloader and tried again, with the same result. So I tried it again to see if I could even boot normally from the Bootloader and it wouldn't even get past the Google screen doing just a normal boot.
Is anyone else having this issue? May try a full fastboot restore back to stock and re root, but I would like to know if anyone else is having this issue before I move on.
Connect your N7 to a computer via usb and then boot into bootloader and you should be able to get in. It is a known issue that you can't get into recovery unless you send a command via adb or you are connected to a pc via usb.

I just booted to Bootloader, fastbooted my recovery, and without rebooting had no issues just using the Boot Recovery option. Just wandering if anyone else was having this issue.

I had android GE 4.3 on it, rooted.
I have the original GE bootloader (that robot) installed.
I downloaded the official 4.4 update through android, rebooted for install.
Now after the install the phone does not boot up anymore, instead it goes into RECOVERY and shows that triangle robot.
I tried wipe of cache and data wipe.
Whatever i try I am not able to get this device into fastboot / bootloader anymore!
It takes longer than usual,, it is stuck in that HTC screen since I have unlocked the bootloader but it does not enter the usual menu.
Instead it just directly goes to the robot.
I tried about everything I could think about,
It seems the OTA really bricked my phone by damaging the bootloader so it does not load at all anymore.?!?!
The only USB accessible feature I see is that in the robot screen it registers a device through USB.
Sadly not ADB or fastboot, it is a volume. It even loads as volume but is inaccessible (like a CD without disk)
Windows recognizes it as WDP FileSystem.
I doubt this will help at all, just wanted to note it.
I am about to throw the phone into trash, if it had not been so expensive.. Anything that can be done to repair this brick ?

Now search for the right adb and fastboot driver. There is a .msi installer (adb + fastboot .msi) something like that. Than push the right recovery via fastboot. Voila

Hi,
I solved it.
It took about 30-50 reboots until the phone entered the fastboot menu.
The problem was that the phone kept skipping the whole fastboot menu and went into recovery instead.
A very strange firmware bug caused by the failed OTA
I started to root my phone this morning. I did the HTVDev unlock, flashed twrp, then tried to flash viperboy's disable RW system protect. This caused my phone to just hang at the HTC screen. I let my phone die and was able to get into my bootloader and fastboot. I tried to push the rom via adb but I kept getting the error of no device connected. Then i tried to flash the stock boot.img though fastboot. This brought me back to the HTC screen but now when I plug it in to my computer it shows up for everything and it installs drivers but the HTC MTP Device fails. Now I cant send commands to reboot through fastboot or adb. Im currently waiting for it to die again to get back to twrp or the bootloader. Any advice on how to proceed?
Thanks,

Likely no need to let it die -- a hard reset (hold the power and vol down for a very long time) should bring you back to the bootloader (hopefully). It'll seem like a good long while -- keep pressing.
From there, select 'fastboot' and press the power button, then plug in to your computer (USB). That'll show USB on the fastboot line.
Then, on your computer, open a command window (presuming you're using Windows) in the SDK platform-tools directory and type:
fastboot devices
If that gives back your device ID, you're at least at a reasonable fastboot. I'd flash a good recovery (I use PhilZ, and while it might be foreign to you (CWM style), it lets you load a ROM via OTG cable over USB if you have such a cable -- if not, hopefully sideload works for you in TWRP if you stick with that) -- just to be sure you have a good recovery.
Then, reboot into recovery.
Your kernel (boot.img) apparently is garbage, so hopefully you can either put a ROM on USB and flash from that (OTG) or adb sideload it. All the ROMs normally have a good kernel so would flash your boot.img properly during install. Were me me, I'd flash O.M.J's stock rooted ROM just so you at least get back to some place of sanity).
If that all fails, you might have to RUU and start over.
Let us know and we'll help out.

ok. can you use adb push in fastboot? also i noticed that my captive buttons blink when i tried to turn off my phone. don't know if that means anything.
OMG it worked! Thank you so much. I uber appreciate it. Today I learned a ton about how android works and how to use adb and fastboot. While the processed about gave me a heart attack i did learn a lot. I can not believe how great of a resource xda is. The knowledge of everyone on here is incredible. I cant thank you enough.
Thanks all,

I have a relatively new Nexus 6. The last phone that I rooted was the old HTC Hero, and things have changed! I had unlocked the bootloader and rooted the phone under 5.1.1 and when I flashed Marshmallow 6.0 yesterday I lost root.
So I decided that I would try to root the phone again. I had problems with the drivers... my PC would recognize the phone when it was powered up normally but as soon as I booted into fastboot I couldn't get ADB to find it.
Then I went to this link: http://www.theandroidsoul.com/marshmallow-root-for-nexus-5-6-7-9-and-player-by-chainfire-84862/
got my fastboot and adb set up and working, followed his instructions to get root, flashed the twrp image, and flashed the SuperSU file. Everything seemed to work properly. Made a complete backup using twerp and transferred it to my PC via USB.
After all this a tap on Reboot System was supposed to restart the phone. Didn't happen.
I'm stuck in a fastboot recovery loop. Whenever I power down and try to turn the phone on I come back to the fastboot screen. When I elect to go into "recovery" it opens the twrp screen on my phone which asks for my pin and then I have the twrp screen with the regular options.
This is new to me... I don't know if access to the twrp screen and its commands is a help or not, but I do realize that the adb and fastboot on my PC is necessary for about anything I need to do and it seems to be working. I believe that I've described my situation accurately...
Any help appreciated!

how about this, adb NEVER EVER works in fastboot mode. that is reserved exclusively for fastboot. you have to use fastboot to flash a recovery, then the recovery to flash supersu.

now it also seems as you have to fastboot flash a factory image as well.

I asked for help before searching thoroughly enough! I figured out that I needed to download another ROM, transfer it into the phone's storage, and install using TWRP. I really didn't understand the capabilities of this fabulous application and had simply flashed it because the thread instructed me to.
Hey, I have a Moto X 2014. I'm running a cynanogen mod on it. For some reason the phone is stuck in bootloader mode, then starts up with the cynanogen logo, then just goes back into bootloader and repeats. I've held the power and lower volume key to get into the bootloader menu. I've tried normal, recovery, and factory and nothing seems to work at all. I cant seem to figure out how to get into TWRP, which I think if I can that could solve the problem by wiping some data and flashing a new ROM. Any thoughts or ideas how to fix this? Also, the phone wont show up as registered on my computer when I plug in the USB cord, so an command prompt "adb recovery" isn't an option I think. If you need more specifics please ask! Really dont want to have to get a new phone.
You can try to enter recovery through the PC command 'fastboot reboot recovery'. If that doesn't work, look up how to flash the stock firmware using fastboot.
I updated my oneplus and i got the TWRP decryption message, so i formatted it back to the stock format.
now all the phone does is boot into the bootloader but gets stuck on the boot screen of Blu Spark 3.1.1
my computer wont recognize it while its in the bootloader or while its stuck trying to boot in twrp
is there anything i can do or is my phone screwed at this point? i see a lot of threads that would answer parts of my issue but nothing that covers this as a whole. id rather ask for help now while there may be some hope.

So no response to fastboot commands, while in bootloader-fastboot mode?
Are you sure you installed the right drivers for your pc? If all else fails, you can do this.
This is how I fixed my phone when i was stuck at a black screen. You can also try a different usb cord or port. Check device manager and see if it recognizes it when its plugged in. hope this helps!

can you boot into fastboot? if your phone can boot to fastboot mode..just flash stock recovery image..then flash rom via adb shell (better flash the stock rom). if it works you can reinstall the custom recovery image or something. dont forget to erase everything via stock recovery..
