Hi all. So I got myself into a boot loop and that usually isn't a big deal on a nexus. Power off. Boot into bootloader, and select recovery. Boom. well I am unable to get into recovery that way. I can reboot into recovery from a rom no problem. And I can adb into it with reboot recovery. Just not through the bootloader like usual.
Any thoughts?

Can't use an app if in boot loop.
You will need a computer and type
Adb reboot recovery
Or if you want bootloader
Adb reboot bootloader

Interesting. Haven't heard that. But would make sense. Twrp and cwm both wouldn't.
And yeah, fastboot commands work fine. So I wasn't lost. Just might not always be near my comp

If you get caught in a boot loop, here is how you need to get into recovery with the Nexus 7.
Hold volume up, volume down and power until it boots into bootloader.
Plug into USB on your Windows Computer.
Open Command prompt (in fastboot folder)
type: fastboot reboot-bootloader
It will now reboot into bootloader. You can now unplug the USB, scroll down to Reboot recovery, press power button, and it will reboot to recovery.
(Please note you have to be unlocked, rooted with a custom recovery to do this!!!)
Update, you don't have to use fastboot, or even have drivers installed. You just have to be plugged in to any comp usb. Mac windows whatever. Then you can enter recovery from bootloader. Wierd huh

Has this bug been fixed? Or will ever be? Need a cwm update or is it a Google problem?
Bootloader problem apparently. All recoveries, including stock can't access. Hopefully someone or Google will fix eventually

Doesn't work for me, when I do that, instead of hanging at the Google logo indefinitaly, it eventually reboots (crashes?) and boots up normally into Android.
But I'll try the "fastboot reboot-bootloader" while being in bootloader thing, if that works, good enough for me.
Yet yes, I hope they'll bring out a fixed bootloader - but I don't really think they will.
So there is still nothing we can do with that? ;c

Well custom rom's advanced power menu works, trinity kernel toolbox, goo manager I think, and apps like that all work. But if you bork it into a bootloop you'll need a USB connection.
Until there's an update from google or someone writes a new bootloader that's how it will be.
If it helps...
After much testing (and after update)
IT HAS TO HAVE USB when VOL DN +VOL UP + ON (only) from off
Later insertions do not work.
I bet it is not a bug, I bet they wrote code for external power check during entry to recovery, etc. Thus, I also bet it is deliberate, NOT a bug, and will not go away.
There are instructions all over the web about when to plug in, on mine it has to (only) be at VD, VU, +ON.
I made a list of operations and screen responses as I tested, if of value...
Iam using trinity tool to boot into recover. It is working fine.

I just had this problem. 2 hours ago I never had this issue.
This started happening when I flash Franco's kernel.
Before I can boot to recovery by going to bootloader then choose recovery. Now I can't!
I even flash stock / re-locked and it still a no go.
I can only boot from recovery thru fastboot or while inside Android.
WTH!
EDIT: Could it be related to the build?
Here are my findings:
a) I used my mom-in-law's nexus 7 stock, never rooted = c8O = It DOES not boot to recovery from hardware buttons (bootloader then choose recovery) - but It boots to recovery from bootloader only when it is connected via USB
b) I have a C9O which was working before, but I flashed to STOCK (recovery using the Toolkit) then It can't boot anymore - so it might not be Franco's kernel
c) Friend's C9O stock, never rooted = CAN boot to recovery without having to plug in the USB.
Weird .. so maybe google will fix this.
Had this problem last night after flashing the latest AOKP. Kept getting stuck at the google screen and couldnt get into recovery at all. I downloaded the Nexus toolkit and was back working in 2 minutes. Highly recommend to anyone who has a similar problem

Maybe search for another tutorial, reinstall your drivers or do the other things that are suggested if you search for your problem.

It's one of the "unlockable" models. Use the "unlock-relock" tool or the unlock script from the unlock guide.

If this helps,whenever I boot into recovery now,a red text saying LGE SECURITY ERROR: BOOT IMAGE or something like that
So you flashed a recovery before unlocking?
If your device doesn't boot at all, do a kdz reflash. If you can boot to the system, use one of the methods mentioned above; you only need root and USB debugging on to use it. If you don't have root but can't boot to recovery, try the "root many android" method from the index, that might do it. If it still fails, do a kdz reflash, then start again (root - unlock - recovery)

I need some big help. I was having issue with my battery and phone powering off when not on a charger. I thought change the OS with Android N beta could help me with the issue.. When I was complete the fastboot commands .. I mistakenly use the lock bootloader command as well. So my devices is suck on the Google Logo.. Can someone help me with this issue?

Well, try first doing a factory reset from the recovery mode.
If it doesn't help, just unlock it and flash everything again.
My bad.. I meant to add that its not let me unlock the bootloader.. Its asking me to select OEM unlock in the setting of my devices
Sent from my SM-N920V using Tapatalk
Does anyone know if you can send the software via adb from the recovery screen
Sent from my SM-N920V using Tapatalk
Try doing the factory reset through recovery, and if it doesn't work, take this steps and sideload the ota:

Tried factory reset several time and that didn't work.. But I'm going to try this method when I get home

Google makes OTA update zips available that can be flashed even if OEM Unlock is disabled. Assuming you are still able to access the bootloader, download the latest Nexus 6 Android 6.0.1 OTA and copy it to internal storage. Enter recovery and flash. This will wipe your entire system, but your phone will be operational again.
From there, you need to go through the process of unlocking the bootloader, and then you can try installing the N preview again.
I have the said phone model, but the trick is I neve rooted phones before. Can I fck something up, like brick my phone? It's on Nougat android.

As long as you follow the steps on the HTC website to unlock the bootloader, you should be good to go.

It's what I wanted to do, went to HTC website on steps how to unlock bootloader, this is what first two steps say:
https://i.imgur.com/c8EAKYw.png
But for me it's different menu after I enter bootloader mode. I have this:

So, fastboot and bootloader options in this mode aren't available at all. I can't progress over step 1 and 2 because of it. I can't highlight Fastboot as it's told in the guide, because it's not there.

Yes, I've tried it both. Reboot to bootloader gives me this menu (which is basically the same): https://i.imgur.com/ZdhS8u2.jpg
And Reboot to download reboots to the same default mode with same options.
