[Q] Broken Power Button

I am trying to fix a friends broken sensation.. and I cant seem to find a way to turn on the phone without the power button. Is it possible on the sensation?

I don't know of a way. How is it broken? Take off the cover, and where the power button should be you will see a raised piece of plastic, very small, and only a little bit raised, but that's the power button. Press it, might take some time to find it

the button is completely broken.. nobody knows any other way to turn on the phone?

If you plug your phone into your computer, you can use adb to reboot your phone. If you dont know how to get\use adb or what it is read this. Follow all the steps and after step 4 simply type "adb reboot" (without quotation marks) and it should start.

i have adb working.. but my computer wont reconize the phone plugged in!

Is the button visibly broken or it just wont work? Did your friend have a custom rom and kernal? Some kernels have the problem where if you drain the battery, the phone wont charge on its own and you will either need another battery or another sensation to charge it.

The button doesn't push down, click, or function. She had it brand new, for about two days. I don't believe it's software related.. and if it is I can't even turn on the phone to change anything

Do you have the HTC adb drives installed, the sensation has specific drivers needed to run, but if your friend has only had it a few days, then get a warranty replacement because it is an obvious hw fault.

yes i have the drivers, will my computer recognize the phone even though its off? the LED light is on. and the warranty became void after she got drunk and fell in a fountain. I managed to get the phone on, and everything was working, i just wanted it to dry out some more, and then when i went back, the power button didn't work. Im sure its just the power button though, and not just the water damage, because she fell in the fountain two months ago, and im just fixing it now.

Water damage will corrode the circutry even after its been dried out,and yes it should recognize the phone even when off, my does and adb reboot worked fine. Does your pc make the hardware connected noise and does "adb devices" not find anything? It seems that maybe you will need to pay HTC to fix you phone out of warranty.

[Q] Is my phone still working?

I accidentaly dropped my phone in the pool. I tried turnung it on without drying the phone first and only put it in rice after that.
Now, when i try to boot the phone it shuts down after it checks the network saying it has low battery. Also, if i try to plug the charger it shows me the high/low temperature level symbol.
I managed to enter the stock recovery menu using the hardware keys and wiped all the data.
However if i enter the fastboot mode using the hardware keys it doesn't shut down.
Is my phone still okay or is there any way to fix it?
The phone is an Acer s500 Cloudmobile.

Make sure its completely dry (mine took a whole week of drying). Try a new battery also. Check the USB connectors and other ports to see if there are any dirt or accumulations present.

[Q] QHUSB_DLOAD: How to unbrick ?

I have bricked my phone while flashing RUU. My phone didn't restart after flash. It doesn't charge and also doesn't respond to long press key combination.
Now when I connect to computer the driver doesn't get installed. Error is "QHUSB_Dload missing".
I found that it is a Qualcomm driver used to identify the CPU serial number and establish any communication with my phone.
How do I unbrick ?
Do I need the JTAG method ?
Can a HTC service center fix this ?

Hi, sounds like a problem i encountered
after hours of digging and end up with not much..i put up a trick that actually worked for me(over and over again for me,cos my H0s keep entering qhsusb_dload mode each time i restart my phone.
u have to take apart your phone, get a torx T5 and a philips screwdriver(search or see at youtube how to take apart your phone.
just take apart the back cover to reveal the mainboard
-disconnect the battery
-connect the phone to charger(charger,not pc/usb)
-keep an eye on the notification led, it will light up(orange) for a couple of seconds after u connect it to charger,then went off
-after the notification led went off, reconnect the battery and pull off the charger from phone.
-(dont reassembly the phone yet)press the power button a few times to see if it will boot, or you can hold the power button for a 10 second.
-in my case,at this point the phone should be booting,but to a bootloop.
-i suggest you enter the recovery when it boots up and do a full wipe.
Try it,do tell me the result please, i hope it will help and do it safely, carefully because anything that happens, i ain't gonna be your warranty desk

I guess this method assumes that the battery has some charge left. Mine doesn't. I tried no result :crying:

I dont think it matters..when you are flashing the ruu how much juice you got left? if u start flashing when the battery is around 100% im sure there should be enough charge to at least turn the phone on..can you tell me more why it didnt work for you? what you went through?

Nothing happened when i connected to charger. No LEDs lighting up.
I think my battery might have drained completely.

Galaxy S6 won't turn on at all.

Hello, today I wanted to restart my device and it just doesn't want to turn on. I cannot access any mode, nothing shows up while charging. The phone was rooted. It was also water damaged in April (1 second in toilet), it didn't wanted to turn on either but somehow I managed to turn it back on and it was working well. When I plug it to PC i can see Exynos7420 for a second and it shows up every time I press power button. I hope it's not hard bricked or heavy damaged inside :/

Well it's defo a hardware failure of some sort, sounds like the main board might be done for. Water damage if not dealt with straight away can cause corrosion of components over time.

Is my phone dead after falling on the floor, need confirmation.

Hey guys,
After two years of constant care, it happened... the drop of death.
A perfect hit on the floor, screen first, perfectly parralel to the stone floor, with the neat "Poc!" sound... :crying:
My phone now does not turns on. Does not vibrate when I plug it and the computer does not detect it.
That's a perfect brick.
I disassembled it and re-assembled, in case of there was a loose piece or cable, but without success.
Is there any chance that it's only the screen, or is it, as I suspect, the end of my beloved OPO?
Thanks for your advice.

What was the state of the device before it fell?

Anyways,I'd recommend you to get it checked from a professional repair shop.There're chances that you might only need display to fix your device.

Well well well.... small update.
The phone is finally partially alive.
I just tested to plug it without the battery in and.... I had the small vibration and OnePlus boot logo. But of course, as no battery, the screen turns black right after.
But.....
If i plug the battery in, the phone will turn on (I did not say Android booted ).
But only if:
- I plugged once without battery, then unplug
- I put the battery back in place
- Then I re-plug the USB cable
Following this, I can:
- Enter TWRP (fully functional, I can backup my rom, wipe caches, etc... and all the buttons I tested were OK, touchscreen seems fine) / (Vol down + plug)
- Within TWRP, ADB sees my phone as an unauthorized device.
But I can't:
- Enter Fastboot mode (Vol Up + plug)
- Boot the phone up:
- Even within TWRP, reboot does not work
- As long as the battery is in, if I power off the phone, it won't turn on again until I remove the battery and do the first plug trick first.
So there is hope!!
Can it be the battery?
If I am on TWRP (with both USB cable and battery plugged) and unplug the USB, the screen stays on, but becomes unresponsive and only removing the battery can turn the phone off.
Or is the phone somehow bricked on a software standpoint? And can be unbricked?
Side note, when I first plugged the phone and it turned on, on the Computer, it installed a driver called "Care Suite Emergency Connectivity"

Replaced display?

No, just tried out without battery. I did but that's tricky. Once you remove the battery, you really need to push the power button first before plugging in the cable, seems the mother board needs to discharged in some way first.
I called a repair shop, the battery might be faulty and put the mobo in security mode... But as I can't access fastboot mode, they said it could be a part of the phone's ROM which is damaged.
Any way to use adb through TWRP to try to dump all partitions to see if any of them are damaged?

Display works perfectly fine at least under TWRP.
The problem is somewhere else, maybe on battery or ROM (not the OS)

Quick update.
There must be a problem with the mobo.
I ordered a new battery that arrived today.
With the new battery, the phone boots up Android, but after some time, it freezes completely.
If it does not freeze and if I try to power it off or reboot, it just shuts down and will never reboot unless I do the battery trick again (remove and put back in place).
SIM is recognized but I don't have network.
I did not manage to get a GPS fix.
Fastboot works, I flashed the stock LOS 13.1 image. But it did not change to the freezing behaviour, and even under fastboot, a "fastboot reboot" just powers off the phone.
That's frustrating!!!
I think it's dead for good. The only reason I see for such a strange behaviour is a shortcut somewhere on the MOBO, maybe a damaged soldering.

Hmm,could be the pcb itself then.Did you get your device check from a professional repair shop?

No, but I discussed with two of them on the phone.
Considering the price of the phone, it's not worst anymore to repair PCB if it can be.
I will go for a Oneplus 3 I think. There is an auction ending on eBay soon and it's still at 170€... And with the 5T coming out, there will be a lot of other good options in the coming weeks.

I have the Oneplus 3 now... Thanks @Mr.Ak and see you guys!!
