Dropped Device and It Won't Turn On

Last night I dropped my N5 pretty hard onto the ground. The screen didn't break, but the device will not turn on. I get nothing when I press the power button.
Also, there is no sort of vibration if I hold down the power button so I know its not starting.
I removed the back cover to see if anything is loose in there, but I do not see anything.
Please help.

Any burnt out circuits? Torn ribbon cable? Have you tried plugging in the device to your computer to see if it shows up?

When I popped the back open there were no loose cables and I didn't see any burnt out circuits. Oddly enough, even though I cannot get the screen to illuminate, when connected to the PC is begins to search for the driver, etc. as if the phone is working.
A replacement is on the way. At this point, I want to recover the data. Ideas?

open the device manager and install the google usb driver manually? Then see if you can't pull files from it?

Samsung galaxy s6 completely dead. Will not power on or charge

Hey guys, So i was using my Samsung Galkaxy S6 one day when the screen went dead. Now it will not turn on or charge, I have tried using 3 different chargers and tried to use all of the button combinations to reset it and boot it into all the different modes. I have even tried to just let it charge for half a day but nothing. Does anyone know whats wrong with it, whether i can save it or if i'll have to get a replacement? I have emailed Samsung but they still haven't replied yet. It is running stock android not rooted and when i plug the charger in the device gets warm but will not turn on or show any signs of life
Cheers everyone x

Try POWER + VOLUME DOWN

Like i said in my post I have tried every button combination including Volume down + Power button. Thanks for the thought though

When you plug it into the computer does the computer see it ?
If yes, then your screen may need replacing. If No there maybe a problem on your motherboard.

The computer does not recognise it either. What you said about the motherboard must be the problem then. Do you have any idea how the motherboard could have been damaged and whether it was a hardware failure or my fault?

Easy on the MB replacement! They're the most expensive thing on the phone. Try the USB port/daughter board 1st. About $6 on eBay. After that if no joy- have to swap in a power amplifier. Here's a link how to

Not fun but might be necessary. I'll bet it's not your MB.

Nexus 5 new screen is not working anymore

Hello,
I had an accident and after that my Nexus 5 screen was broken. So I decided to buy an new one from Amazon (~60$) and I tried to replace the screen on my own.
Yesterday I replaced the screen with a YT-Video, then I charged my Nexus 5 an the "Charging-Symbol" showed up.
After that I left the house for 2 hours and when I came back (I left the Nexus at home for charging ofc.) I tried to turn on the phone and nothing happened.
Then I tried to press power and volume down to get into the boot-menu and this also worked and the screen showed everything perfectly (!) and then I tried to start my handy from the boot-menu.
Until then everything has worked well but during the start progress I noticed that the (starting-)animation is really slow and laggy, so I decided to try to reboot my phone by holding power off for around 10 secs.
I tried to start my phone one or two times more and tried to get into the boot-menu, restart bootloader, etc. and then I realized that my phone didn't even want to work anymore. I could(and can) neither get into the bootmenu nor simply start it...
Do you have any ideas?
What suprised me the most is that it stopped working so quickly, so I concluded that I replaced the screen right but anything else went wrong...
Please help me :/
PS:
USB-Debugging is turned off and I cant access my phone with my pc or anythin else

Leave the phone on the charger for about an hour and then try to get into the bootloader.
When my phone is in the process of booting and I force it to power off by holding down the power button, it will not power up until I either leave it on a charger for a bit or leave it power off for a bit, usually 5 to 20 minutes.

Thanks, now I could get into my phone and enable USB-Debugging with much lock D)
My problem is, that my phone runs very unstable and shuts down often so I can't really work with it.
Do you know any solution and the more important question:
How can I save my data? I think, that I can save it anyhow if I enabled USB-Debugging with the bootloader and a pc, can't I?

Yes, you could pull the data from the phone using ADB commands.
You could also flash twrp to the phone. Once flashed, you could boot into twrp, mount the data partition, and copy data from the phone to the computer.
You could also use twrp to create a nandroid backup for safekeeping.
Is it possible that there is a loose connection in the phone? Have you tried disassembling and re-assembling?

I have now moved on!
My charger cabel was broken but now I got a new one!
I can start my Nexus (with some issues) and it runs but sometims it still shuts down and always when I try to plug in my cabel into the Nexus the screen gets black (but on the side you can see that the screen is light up in some way, idk...)
Is there a reason for the heating and for the shut downs? :/

I'm not sure but it seems like the screen has suffered a hardware malfunction because you can see that the backlight is on but no image.

Reset, etc..

With a hardware failure, there's nothing that software can fix. Did you try disassembling and re-assembling the phone?
With the old screen, can you see anything on screen? Did the phone power up and charge properly? If yes, put on the old screen to test the other components to see if it charges and powers up.

Yeah first sentence makes sence..
I swapped software and hardware, sry
my other screen doesn't work at all, completly destroyed...
The problem is that I can't imagine what should be the failure...
And yeah, I already tried disassembling and re-assembling it...
Still same problem

I have used cheap 3rd party screens to replace a few N5 phones and they quality is very inconsistent so I wouldn't be surprised if a 3rd party screen fails after a short period of use.

Nahh but the screen works I think..
Everything looks clear etc and the screen wasn't really cheap with 65$-70$ I guess..
I think it's something else because my phone gets really on near the CPU and this can't be because of the screen...

Where did you get the screen?
If it gets really hot near the cpu, then something else is going on. Could it be possible that there is a short-circuit somewhere?
Since the value Canadian dollar has dropped, I'm also paying about $60 for what was a $40 screen.

Yeah, I also thought about a short-circuit but I don't know how I can test this.
When I try to start my phone it fails like 4-5 times and then it works most of the time. The fail looks the following:
The "Google" logo appears and then suddenly the screen gets black, but not the "out"-Black (so that screen it out), I mean the "on, but black"-Black (hope u can understand.. xD)
During this 4-5 Tries my phone feels like 40°C-50°C (sry im from Germany, idk the conversion to °F value.. )
After this (I got the phone running one time for about 20 minutes) the phone doesn't heat up so much, if it starts right I think that the temparatur problem is over, but there is still the problem (also if the phone is running for 20 minutes) that it suddenly shuts down... :/
Sorry, idk much about canadian dollar, like I said im from germany and I payed around 65€
Google says, that this is around 67 (US-Dollar)

I don't know what to suggest other than either getting a new battery or new screen. Both items can be very expensive.

s7 hard bricked (qualcomm version)

Hi,
I flashed a rom that did something bad to my phone. After reboot it just stays black without any response at all.
I've tried all the key combinations and just tried the USB Jig (confirmed the jig worked on my S3) but nothing.
Is there any way to get into download mode?
I've heard about JTAG, but not sure if that will work.

First, try to connect the phone to your charger to see if any LED lights up, if this doesn't happen, try connecting the phone to your PC and see if ODIN detects the device, if that also doesn't work...the best course of action would be to send it in for repair, although chances are you've hardbricked it.

Possible it is stuck in some sort of loop, without having any LED to indicate it would be impossible to know
The charger doing nothing seems strange though
If you had an LED showing I'd suggest waiting for the battery to drain then trying to enter download mode again, but I guess if you've tried everything else and are considering opening it anyway for a JTAG, then disconnect the battery first, see if you can get back in after reconnecting it

Yea tried all that but no luck.
I will try for the JTAG, but need a heater I doubt a hairdryer will be enough to pull the back off.
Also need the JTAG machine itself

opened the phone and removed battery but still nothing, it seems JTAG is the only way.
anyone knows how that works?

Are you getting some sort of output?
I'm using the Exynos variant, I've yet to encounter anything that wasn't solved by holding power+vol down+home for 40-50 seconds (it'll boot to download mode eventually usually)

Tried for one minute and no result.
No output at all, nothing gets recognised in windows. No LED, no nothing...

Well, some users also reported sudden blackout with no response at all, it turns out it was an emmc failure. He then proceeds to send in his phone and luckily, it was replaced. Your mileage may vary, you could try playing "dumb" with Samsung. After all, with the phone dead there's no solid way to tell if KNOX was tripped.

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.

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"

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.

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!!
