[Q] HELP! Shield Not Booting! - Shield Q&A

Yet another issue with my shield but this I can't figure out. I was gaming through hdmi and after i was done i closed the lid and opened it, it would not boot. It WILL charge, the nvidia logo pulses and thats it. Computer doesn't detect it. Still no idea. It is rooted but was done properly and was done awhile ago. Is there anything to do to hard reset or boot the bootloader or anyway to boot like on android phones? Please help! (I will keep updated) Edit 1: hooked back up to tv, it detects signal but it's a black screen.

Hold the power button for 15 seconds. That will hard power it down...

running cleanrom 3.0, no matter what option i choose in restart menu or shut down, it just does a hot restart
wish i could do a god damn battery pull
[EDIT] This self resolved this time but wtf??
To simulate battery pull hold power button it will blink a few times then turn off. Also disable fast boot in power options.

I had this same problem today.
But the advice given above didn't work for me?
I had to do a factory reset on the phone.
Then the trick to shutting down the phone is to do it BEFORE you set up the phone, immediately after the first bootup.
Just for the fun I decided to brick my phone on purpose. Holding the power button will effectively turn the phone off. Got back into my recovery and reloaded a backup.

Not much of a "brick" if you can just recover from a backup.
Shoot, then i probably brick 4 or 5 times a week

I also experienced this issue yesterday and was able to resolve the issue. Although I am running sick-sense, this might work for you to because I think the issue is kernel related. Try plugging your phone using the charger, and unplug it. see if it resolves your problem. Let us know if this helps so other who might encounter this issue have a fix.

[Q] No power One X - Wrong ROM install

I've did some searching on this and tried everything listed but I may have a unique case here. I had a buddy call me a couple days ago and tell me about his issue with his One X. I started digging on here and found a couple of tips and tried them all for him and no go.
I asked him what he was doing when this happened. It is a Rogers One X and he attempted to install a CM9 ROM for the international One X. He assumed a One X was a One X. I've only dabbled with my Galaxy Nexus and Transformer Prime, but I'm assuming this is the issue with his phone. Am I wrong?
Is there a way to fix it? I've had the phone for a couple of days and I can not get it to power up. The LED doesn't come on either when the usb cable is plugged in. I've tried a couple different chargers and cables and same result.
Hoping I can some how save this for him.

Tried this...dead. No response from it at all. Would the CM9 ROM push out a different boot.img file and that be the problem?

charge it fully
power it up holding the volume button DOWN. If you can get to the bootloader you're not bricked and can re-install the rogers firmware.

yes...but it should still hit the bootloader, hell even recovery. try the same method with vol up instead... then plug into pc... see if there's any connection.
This thing takes forever to boot compared to me older devices. I'm thinking it's not totally off... try holding the power button for a long time... like 15 seconds +. see if any lights flash..
The trick is we need it in a full off state and power it up with vol down and power.
It could be in a kernel boot loop that you can't see anything.

Nope not at all. Other then voiding the warranty, which with the bootloader unlocked is probably voided already, I'm debating cracking into the case and unhooking the battery and rehooking it up.
If it's dead it has warranty

alright so its hooked up to the comp, it detects it. It comes up with needing a QHSUSB_DLOAD driver. Did some Googing and tried some drivers, but it won't install. Any ideas? I'm hoping I can save this.

It actually might be recoverable, but it's a lot of work.
Do this.
On a linux machine, while plugged into usb - push and hold the power button for 10 seconds. Release it. IMMEDIATELY and REPEATEDLY do ls /dev/sd*
Do the ls over and over again (for around 20 seconds or so) and see if a bunch of new devices show up and subsequently disappear.
If they don't, push and hold power for another 10 seconds, release, repeat.
If you get devices to show up, it's recoverable.
He bricked, is a shame but that's the risk you take when you flash a ROM meant for another phone...

Can't get into hboot / recovery / fastboot

So, I thought I knew what I was doing, but apparently not.
I tried flashing XYLON.
Now, the phone gets stuck on the boot animation. I've been trying to get it to work for the last 12 hours. It either gets stuck on the boot animation, or on the "Android is updating" screen. I can't even get into the hboot to boot into recovery.
Can anyone recommend a course of action to bring my phone back to life?

Hold down power until lights flash 7-10 times. Simulates a battery pull. Then push volume down and press and hold power button for 4-5 seconds, then release power while still holding volume down.. should go to bootloader. Sounds like your not timing it correctly

Well, I'm still trying that. I've done it the way you''ve mentioned it here as well. Trying it again now. I've never had problems getting into my hboot before. :S
Something just seems wrong.
Once I get back home, I'm gonna pull the phone apart and check if something's wrong with my volume button. The Vol. up stopped working, but vol down was working just fine....
Let it boot as far as it will go and see if adb will recognize it. If it does adb reboot bootloader

I've tried that.I kept it for an hour, let it go as far ahead as it would. ADB does not see it.
I agree, if you cant get Into bootloader its a timing issue. Try holding the power buttons until the capacitive buttons blink 7 times or so, when the screen goes black let go of power and press and hold only volume until the bootloader comes up. This way is almost impossible to miss.

Seem like I've been missing the timing all day. :/ I'm gonna check my hardware this evening... lets see what happens after that.
I have heard of a case where someone had to physically disconnect the battery before they could get into bootloader but that's a *****. Since you're s-off you could try RUUing.

RUU doesn't work. I can't get RUU to detect my phone. It doesn't boot up. It's stuck at the boot logo. And even if I leave it connected to ruu while i'm trying to reboot, or trying to get into hboot, it still doesn't detect my phone.
Well... You could let the battery drain and then charge it for about 10 mins then unplug from power and press and hold power and volume.

Well, I've already pulled my phone apart once to replace my broken screen. Which is why I'm suspecting it could be a hardware problem. Somehow. *sigh*
And I'm in. Finally.
I let the phone's battery drain completely. I pulled apart the phone, and pressed down on the volume + power pins/buttons directly. And I got into the boot loader.
I'm currently restoring the backup of the rooted stock rom I always keep on my phone storage.
Thank you everyone for your suggestions and support.
I just saved myself a whole lot of money. ^_^

So my situation is similar but my htc inc s is brand new from ebay china seller ( I live in Greece), is s-on, never messed up with, never rooted all factory. It worked great for few days and after the first OTA update I cant get into hboot, adb doesn't see the phone, always the updating symbol on screen.Tried battery pull, volume down + power in all the possible timing and combinations but yet nothing! Also I tried battery pull, volume up + power it vibrates 3 times orange lid is on and black screen (on the forums is said that this is diagnostic menu). So I think maybe this phone is a refurb and not new since the answer from HTC global support (after sending my IMEI and S/N) is that this phone is for Indonesian market and that its warranty expired year ago! Can you help me in some way guys...

Tf700 powerbutton fail

Hi . i recently got my tf700 and it was very laghy so i rooted it and installed cromix and it ran much smoother .
But after i shutdown the tablet i can power it on . when i hold down the button it's Boots up normly but as soon as i release it it shutsdown and not just shutting normally but like it looses its power . i think that somthinf happened to the hardwere and now without holding the powerbutton it cant get any electricity.

Because it sounds like a hardware issue.
You will have to RMA it. Have you spoke to ASUS support? Likely you'll need to pay the Motherboard repair fee as well
Turn off the tablet normally. Then plug in the AC adapter. Plugging it in to charge should turn on your tablet without you having to press the power button at all. Try turning it on that way and see if it stays on.
Well it does turn on when i use the cable
But i still dont know how to fix the button problem

Does your power button still "click" up and down when you press it ? because mine got stuck in the down position which might cause it to reboot over and over but not shutdown? Does it vibrate when you release the button before it turns itself off or just instant dead screen?
No . it does click and when i release it , it shutsdown amidetly like the power is out wich is realy wieed

You do, but they'll likely try to get you to cough up for a new Motherboard.
So on the sounds of it you'll either have to do that to fix it, give up on it and sell as broke, or see if a local comp shop can open it up and see if there is a faulty connector to the power switch.
Unless anyone else has a solution, but it sounds hardware based to me
You seem out of luck but have you tried keeping it pluged in for a long period of time and maybe repetitively pressing the power button really hard to see if you can lossen it up a bit. Also you can turn it on using the cord correct? What happens when you unplug it? You lose power?

First one to brick their M8?

Recently rooted it, installed Xposed, installed a module for smooth status bar or something, did a soft reboot and now it won't do anything.
Xposed doesn't seem to be working all the well with this for of root.

So you are essentially saying that because we do not have system write access, it is not possible to brick the phone per se?

I was holding Power and Vol Down like on my DNA, turns out I had to hold Vol Up.
For some reason, I tried to boot into recovery from Goo.im and I wound up with a red "!". Holding the power for over 3 minutes did nothing. Holding Volume Up plus power put me back in business.
I've had that issue several times now where I was horsing around with xposed modules and rebooting and it would just freeze with the screen super dim and the Verizon logo just barely perceptible. Holding power forever did nothing. One thing I found that ALWAYS recovers it for me is holding power and volume UP for about 30 seconds. It hard resets it. Works every time for me.
I was starting to get scared too as I'm coming from The Galaxy s4 and am used to being able to battery pull.
