[Q] tablet won't turn off for replacing digitizer - Transformer TF300T Q&A, Help & Troubleshooting

Hi,
My tf300t got its screen cracked so touch screen is non functional.
I'm trying to turn it off so I can open the case, but it always reboots no matter what I try!
Tried long pressing the power button for 30 seconds but it always reboot after 8 seconds.
Any suggestions? I don't want to open it up while it's on .
Can I shut it down from fastboot mode?

I remember there was a manual Power off option in TWRP (idk if it is still there). Have you tried that?

I have the stock bootloader - it says
Code:
"Adroid cardhu-user bootloader (1.00 e) released by "WW_epad_10.4.2.9-20120809" A03
I'm inclined against flashing a bootloader (only as last resort).
I am able to get into fastboot and issue fastboot commands. will that help?
"fastboot reboot" only reboots..
by the way, the device is still locked (getvar returns "unlocked: no")..

How did you turn it off if the touchscreen wasn't working? By pressing the power button would cause it to reboot endlessly. If you don't have a dock or adapter to power off properly, one thing I did before was to click the reset button (through the hole below the SD card slot) and press the power button simultaneously, then keep holding the power button for 10 seconds after releasing the reset. It did turn off the tab completely. Failing that, just pop off the back cover and turn off the service switch. The cover is not connected to anything electronic so it's ok. That'd cut off the current to the tab. It can be done, just be careful.

I didn't turn it off, that's the problem.. I got it yesterday from a guy after his screen cracked.
he gave it to me turned on and I want to replace the screen, so the only thing I can use are the hard buttons.
I only have the power adapter + usb cable.
are you sure about that reset button thing?
EDIT: found info about the "service switch": http://forum.xda-developers.com/showpost.php?p=46159071&postcount=5
EDIT2: did it! thanks graphdarnell!!
now moving to step 2 - ordering a replacement digitizer..

major problem...

So... I've tried to update my rom and I've done it. Didn't like the ROM and tried to change it.
soooo. I messed everything up. My magic can't boot (it stalls on the boot screen showing "HTC Magic") and most important, I can't enter fastboot to restore a working ROM
Any ideas on this one before I go to HTC Support?

can you not get to the mode pressing home and power.
from there you should be able to use adb push to send new update to sd card

nope. Every key combined with the power button just boots the device and show the "htc magic" logo. nothing more.
I had the same sort of thing once. I removed the battery and before I put it back, I already pressed the home-key as well. Then it went into fastboot mode after I put it back in. With this way I could sent a new update.zip to the phone, flash it and then it was working again
Hope this helps

Well, it's not hard to send the update.zip. I can use a microSD 2 USB and copied it that way.
By the way I think it's the "return" key to enter fastboot. Not "home".
Tried the battery-removal trick. Didn't work.
Take out your battery, hold the volume down button and put the battery back in whilst you're holding the volume down. This in theory should bring you to fastboot. Just keep holding the volume down until you reach the fastboot screen. If after you put the battery in, nothing happens, keep holding the volume down and press the power button...
Should work...

One other thing to try is to hold the two left most keys on the front of the phone (these are different depending on your phone brand) whilst holding power, this will take you to a recovery screen where perhaps you can do something from there?
I'm assuming you get to see a splash screen first and then you see the HTC Magic logo...

the 2 most left keys are the "answer" and "home" buttons. tried it. still getting the logo.
the phone vibrates and shows the logo...
Turn it in for repairs.

Well, I am exlcuding the green call button and the red end button (which you use to run on your phone), but if it's freezing at the logo where it vibrates, then there is a problem.
I had a similar thing, but I was able to boot my phone into fastboot/recovery with the battery trick.
My two left buttons on my device are the home button and the menu button. Try holding this down when you put the battery back in. Unfortunately, the situation doesn't sound too hopeful.

[Q] [Q} Broken Power Button, Phone won't go into Recovery or Download Mode

The power button on my phone recently has stopped working. I need to get it warrantied, but I am running CM 10.2. I need to Odin back to stock, but I can not get into Download Mode or the recovery. When I go into Download mode, the initial screen pops up, the one where you choose to hit up to continue, or down to reboot normally. After I hit up, the screen goes black and nothing happens.
I really need to get back to stock, as Bestbuy are being dicks, and demanding I do a factory reset before they send my phone in.
Anything? I still need help on this.

This has been covered at least 10 times in the past few months we need a sticky. Take your battery out hold your phone so the power button is facing a table or floor and slam that side a few times it should work again (Temporary). You might need to hit it on the surface really hard 10-20 times before it works. Just not to hard or else you might crack the screen. I used a mouse pad to soften the impact. This trick no longer works for me so I ripped the button off. After about a month of doing this I needed to use things that would only hit the button to make it work. About a month after that nothing worked so I just took it off the motherboard and now boot from a off state by plugging into the wall and enter odin mode deny the prompt and it kicks me into a workable state.

I can get into the system just fine. When I go into the recovery or download mode, it doesn't stay in that mode. I tried the banging thing, and it made my power button go from intermittently working, to not working at all.
keep doing it until it works. The button is sticking that is why it reboots/stopped working.

It sounds like your power button is physically broken, and it is activating intermittently, which is stopping the phone from entering download mode. My only experience with this problem is my own phone but ultimately mine got so bad that I had to rip the button off the motherboard, as ThePagel did. Your symptoms sound the same as mine.
You can try this procedure to get into recovery, which works for me without a power button. You will probably have the same problem you are having now with the phone rebooting on its own before you actually get into recovery, because the power button is activating.
1. Take the battery out of the phone and unplug it from USB power.
2. Plug in USB power.
3. While holding down the volume-down button and the Home button, insert the battery (this is a little tricky).
4. The phone should start and warn you that you are entering Download mode. If you want to use Odin to return to stock, do that now.
5. If you want to get into Recovery instead, press Volume Down to reboot and then *immediately* push and hold Volume Up and Home simultaneously. The phone should reboot into recovery. Mine does.
If that doesn't work, and you can't get a new phone without returning it to stock, then prying the power button off the phone's motherboard may be your only solution.

[Q] Stuck in system recovery, no power button

So my power button has stopped working. It started by constantly turning the screen on and off, then bringing up the power menu again and again. I left it overnight to sort itself out. When I woke up, the phone had managed to reboot into safe mode, and then I tried to reboot back to normal. Now, the power button (and volume) is completely non-functional and the phone is stuck in (stock) system recovery.
Is there any other way to get the phone to reboot normally without use of the physical buttons?
I'd like to be able to do a more recent backup before I get the phone replaced. Thanks.
Have you tried pressing or holding the yellow Off button under the microSD/nanoSIM flap?

Yes. It would reboot to the same recovery screen.
The phone eventually booted normally. I think there was water in the power button, causing it to register button presses on its own and eventually not responding to the button at all. It must have dried over time because the button works fine now.
Then do a backup and do it quickly, 'cause you don't know what it's gonna do next...

hello
i have nexus 5 that in the last 3 mounts was untouched because i went back to dumb phone, but now my works need me connected to the internet so...
my phone stuck on the google with the unlock\lock screen, every 2 sec its resets, then again same screen for 2 sec, over and over again.
when i try to get in boat-loader, after 2 sec it again reset and go back to the unlock\lock screen.
when i try to plug it in to PC -nothing
when i try to open the phone and check the power button, it is all good and nothing pressing on the button. and its still loops over and over(didn't tried the "band on the edge" thing -its still plastic and small parts)
if its a motherboard problem can i have a price for it and information how to replace it
and if not i am willing to try any other option
thank you and have great day
The power button doen't need anything pressing on it to be a problem.
Open the phone, remove the motherboard, quickly press and release the power button, using more pressure than normal and try again. If that doesn't work, you may have to replace the power button.
The cheapest way to replace the motherboard would be to find some selling a phone with a smashed screen and a working motherboard.

Cannot power on phone

So before, my power button gave me issues where it required substantial force to be used in order to get any response. Now all of a sudden, the fingerprint sensor went out as well as the power button itself. When attempting to do a hard reset to correct the problem, the phone won't turn on anymore. So it would seem that the power button no longer works and now I cannot turn on my phone . I've attempted to go into download mode or even the bootloader with little to no luck at all.
Does anyone have an alternative way to power on the phone so I can attempt to backup my data?

This took a lot of trial and error with various button combinations, but I think I found a solution that works.
You must use the wall charger and cord. That's what I used.
1. Press and hold the volume up and down button at the same time.
2. Plug in the wall charger to the charging port.
3. You will see the lg logo on your phone.
4 Right when you see the lg logo unplug the charger from the phone.
5. Continue holding the volume up and down button.
6. LG logo will go away and then come back and your phone should boot.
5. Release the volume up and down button when it starts to boot.
Note: If you don't pull the power cord right when you see the lg logo, it will go into charging mode.
I was able to successfully boot my phone from a powered off state this way 3 times with no problem.
Once you get it booted, you could download an app from the play store to remap a volume button to be a power button as a temporary solution.
