Can't hardware boot into fastboot.

[kdb424]

I think I'm bricked. My shield is stuck in a simple bootloop and should be considered a softbrick. I can't seem to get into fastboot. Forget adb, that's not responding, but I'm still getting the android boot logo. I've tried so many ways. Holding the button, mashing the bettenbetter, plugging at the brick, power at the console, just about everything. Anyone figure out how to get into fastboot with hardware? If so, please let me know or I'll be throwing this out. It just won't seem to respond to fastboot. Such a shame.

EDIT: Android figured it out somehow and just booted, but I'd still like to know how to get into fastboot for when I'm not so lucky next time. Or any other way to get into recovery.
EDIT 2: Thought I posted this in troubleshooting. My mobile data was lagging somethinf fearce. Sorry.

It can be tricky mate. The way I did it was to unplug the device and then put the power cable back it. As soon as you plug the power cable back in hold the power button down until the fastboot menu appears. It took me a few tries. Of course if you have adb working the easiest way is "adb reboot bootloader"

I have done it once before, but it didn't work the way that their confusing instructions said. I'll give that a shot though. When android just flat out won't boot enough to access ADB, it can be problematic.

It certainly doesn't help that there isn't a physical button on the Sheild, so your not absolutely sure your pressing in the right place after re-inserting the power cable.

In my experience the whole button is sensitive, bit that's still a pain. I have no problems booting my phone to recovery or fastboot, but that's just nuts. Oh well. Hopefully teh learned something as I'm sure their techs are complaining too. It is a consumer device, so I guess I can't be too mad, but still, they expect us to reflash before an RMA when needed sometimes, and that's not fair to ask with thes device lol.

I have the same issue here. I was able to get in fastboot hardware wise a bunch of times before. Now I think the device is done. I've tried every combination. What's weird is I did get a flicker of the bootloader continuing once. What could have changed that the bootloader is not responding anymore? How did you get lucky, let it sit there loading for a day? I've tried to see if fastboot commands can reboot the bootloader when I plug it in timing it correctly. So frustrating.

Yesterday from many many trying times I did it only once and don't wanna go cross again and don't ask me how I don't know how and still don't know how. I did everything by "book/instructions" finally give up and just randomly (panicly ) pressing / holding finger on it, power on / off...and then somehow bootloader screen appear. That should be fix by Nvidia

I hope some developers out there will create some magic solution how enter easily in bootloader mode, like using micro sd ports some modded scripts or usb ports where in plugged in mode console entering bootloader mode or recovery etc.

Glad I'm not the only one having issues. I've been trying everything with no luck. I'll give it a few more tries and then It's going back. Following Nvidia's instructions is BS. There is obviously an issue going on here that needs to be fixed.

It will definately go into fastboot, it's just a matter of timing. It's really tight. In the end I stopped following their directions and just tried a bunch of random stuff. I tried so much I don't know what worked, but doing what they said wasn't working for me.

Same here - finally haotic random pressing / unplugging and at the end done only once

Im also in the same boat

Just tried to flash stock 2.1 and Full android 2.1 and now the shield wont boot into anything

Im trying the hardware bootloader method but thats not working so far.........ive just unplugged everything, and giving it a while before i keep trying.........i suspect i might have to try rma......that'll be fun...........(im implying, that it wont)

Same here, mine is stuck on on screen and stating production fused , and couple of options like recovery kernel forced recovery, none works fallowed nvidia instructions , tried downloading SDKS And followed commands nothing working , as well tried holding power button , and unplugging and nothing works, I will try what you guys did and see maybe I get lucky somehow

I have a Shield TV power device but the screen is black and I can not go to the Hardw

I have a Shield TV power device but the screen is black and I can not go to the Hardware Bootloader Access:crying::crying::crying:

Same here - when I plug int he power the green light comes on for about half a second then goes off.

Quite infuriating really.

I get a screen that sasys "continue booting..." and then it loads normally do I need to let go once it says this or should I continue to hold?
