Dropped my One from a very small height - died completely

Hello,
I dropped my HTC One to a hard floor today, from height of less than 50cm (20").
The screen was on before the fall, battery was >90%, everything was working. After the fall, the screen was off, led off, nothing happening from any buttons.
I have tried long-pressing powerbutton, powerbutton+volume, no effect.
I have tried charging, no effect. Even the charging led doesnt work.
I also tried powering it on under bright light (?), no effect.
I had my bootloader unlocked, CWM recovery and Android Revolution HD rom installed (http://forum.xda-developers.com/showthread.php?t=2183023)
The phone had Nillkin protective case (http://mobilemate.yetaa.com/htcdopod/nillkin-htc-one-m7-hard-protective-case.html). I can see no physical damage on the phone, not even a smallest scratch..
Any ideas, what can I try to get it working, before sending it for repair? (Let's hope it goes for warranty. I really don't think it should die for such a small impact..) All ideas welcome!
*EDIT* My phone was working for a second, but broke again. In repair now.
If you connect this to pc, and you press Power, pc can recognize it?

Thanks for your answer.
I can see no devices on my device manager, adb doesn't recognize any device, fastboot doesn't recognize any device. So nope..

Did you longpress power when it was connected?
Because some people resolved this problem...
Why do i think that the battery moved inside so it turned of

Hey! I just put it in a charger again, and after a minute I suddenly noticed that the charging led light up! I tried pressing the power button, and it booted to bootloader!
I then went to fastboot -> Reboot, to get it to boot normally..
There was a sudden flash of the HTC logo (boot logo). Lasted less than half a second, then it died again.
Now it seems completely dead again..
Low battery

Shouldn't be. I had it >90% when It first went dead..
Now it's on charger and doesn't show the charging light.
It also was on the charger the whole time, when I last got it to bootloader and when it died again.

Hi, and thanks for your answer.
Tried both USB3 and USB2 ports. Can't get the phone to boot to bootloader. Nothing happens - no led, no vibration, nothing on the screen.

I'm having exact same problems except I did not even drop my phone, the screen and phone went dead as I was using it. I've been charging it for hours, no response from any lights or anything. I have tried pushing the buttons to force a reset to no avail. When I plug it into my computer it does not recognize it or even acknowledge that it's there.
Hey, my phone works again!
For the millionth time, I tried to start up my phone. No reaction.
Then I connected it to the charger, and the charging light came up.
I then pressed the power button... And it started! Now it works 100% normally, I have shut it down and rebooted and shaked and tilted and knocked it and removed charger and everything, it just keeps working 100% normally! And the battery was at 99% when I got it started.
I don't think the initial cause could be something (battery?) connected loosely, as it just started working all of sudden, and I cannot easily reproduce the error!?
Well, I'm glad it works now. And I'm glad I chose HTC One over GS4.. Self-repairing cellphones in 2013... What next?
Good, i'm happy that your one works fine!!
Enjoy with this!!

Try connecting your charger and let it charge for about an hour, you should see a red led near the top of the phone. Then try clsA's method with the light. It that still fails you probably have a dead battery and will need to replace it.

Looks like your phone just won a trip to the repair shop. Either a bad battery or a failed motherboard. It happens, my HTC One x failed like that 3 weeks past the warranty. Was just sitting on my desk then turned off and never came back to life. At least, yours is still under warranty.

[Q] Sony Xperia Z1 - Completely dead (no led/no nothing)

Hello.
Please take your time to read this message.. It contains detailed information about this case...
I have a broken Z1 phone which I'm trying to fix. It all started with the phone turning off randomly, and wasn't possible to turn it back on. Not using the power button/red reset button or using power + volume up together (this worked previous times).
When the screen died, I could see white blocks of pixels moving around a few seconds before it completely shut down. There were no signs of life after that, the LED was completely dead as well. The computer didn't notice the device if I connected it with a USB cable. If I tried to charge the phone, the LED wouldn't turn red.
I decided to wait for a week in order to see if the battery could run out of charge. So after a week I took the USB cable and started to charge it. The LED turned back on, with a red color, which is correct when it is charging.
I thought it would work to boot - but nope, it did not work at all. Now is the time I decided to open up my device. I used a heat gun to heat the back edges of the phone. I then used some palastic tool to open the back cover from the phone. It all went very smooth and I disconnected the battery from the phone (removed the cable from the motherboard).
I let it be for about 10 minutes. After that I inserted the cable back to the motherboard, and tried to boot. This time, nothing happend again.. So I started to charge it, and a screen came up saying 1% battery... So I let it charge the battery for a few hours until it rached 100%.
The battery is now 100% charged. The phone still refuses to boot up the first time. The second time I tried, it worked. I was able to connect my phone to my computer, so I took a backup of all files. I downloaded Sony PC Companion, and made a factory reset. This went very smooth as well.
I thought everything was fixed after this - but nope. The phone randomly shuts down a few times, and each and every time, I'm just starting it again (it did crash both when I was using it, and when I did not). I was speaking on the phone with it yesterday for 1 hour (used a bluetooth device), without the back cover connected to the phone. The call went very good and the phone didn't crash anymore that evening.
I thought everything was good, once again. So I was letting my phone be powered on during the night when I was sleeping. When I woke up, I went to check the phone - and it was: dead.
Since this, I have not been able to power it on again. No matter what I do. I have tried to disconnect the battery, check for cables that aren't fixed and so on.. But everything seems to be OK.
My thought was that the battery was bad, so I went to a store in order to check if the battery is OK or not. They tested the battery with some kind of device, and said it has about 40% charge left.. And they didn't see any issues with it.
So... now I'm wondering, what kind of parts do I need in order to fix my phone? Is it just a new battery, or is it the whole motherboard that is gone? What do you think? I know you guys are very experienced, so I have high hopes of help from you.
Regards
Hello!
Sorry to hear about what happened to your Z1, I'm currently in the state that my phone has a red LED when connected to anything and stays like that, PC doesn't even recognize it.
I see your problem is different, I'd suggest you to start here and hope for the best. Unfortunately I can't do that to my phone because PC is not recognizing my device.
Good luck
Regards,

I decided to take apart the device even more, and I found something on my motherboard, which probably is rust.

Download Sony PC Companion, plug in your phone and follow the instructions in order to reset your phone. If that doesn't work, then you have probably had water or some other hardware failure.
Is this problem will cost me a lot of money if I'll bring it back to Sony for them to repair?

Not if you repair via Sony PC Companion. It will re-install the system on the phone, so in case it is a software error, it will be fixed.
However, if that doesn't help, then you need to check if you have any warranty valid on your phone. Even if you have warranty, it is not sure that Sony will cover costs for repairing your device. For example water damages will most likely be refused, and you'll have to pay for it yourself. I don't know how much it would cost though.

Phone stop and won't turn on

Hello,
I have a Redmi 4A with RedFox as Recovery and Pixel Experience ROM randomly the phone turn off and then it won't turn on anymore with power button and won't charge neither.

Probably a dying motherboard. It happened to me twice before and the solution that worked for me was to charge it via PC/laptop and wait a few hours.
OK, thanks I will try but it seems it won't last long.

My guess is that they tried to update when the battery was so discharged, then the update didn't finish correctly, still seems no battery.
When you charge the battery again, try to enter to recovery mode and do a factory reset, try to boot.
To enter to fastboot mode you can, either press volume down + PWR button, or pressing volume down and at same time, connect to your PC, but not much you can do through it, if the bootloader is locked, and plus, the user didnĀ“t start the process to unlock it.

I tried to connect it to the PC holding Volume- but nothing happens, the same battery symbol appears

Well, you don't need to charge for 24 hours, it seems to me that something in the hardware is damaged or was disconnected, like the charging flex connector, it could be an internal error, you should check it with the help of a technician, the symbol shows no charge at all. After you solve it, at hardware level, then you should try some tips at software level.

Hello brother. Im facing the same exact issue. did you fix the phone. Any way to fix it?
Today my phone has fully discharged and I have the exact same issue.
Impossible to boot and I cannot charge it, as it results as the blinking of the battery icon...
On my side, if I plug the USB-C, it does not even says it charges / but it vibrates each ~5sec with the same (empty) battery icon...

hi..i have already posted this on a thread in the morning. i have same exact issue.
I dropped the email to xiaomi and they after lot of back and forth emails, and trying everything out, they asked me to visit a service center. apparently after doing some research the only way to fix it is by opening the phone and disconnecting the battery and connecting it again.
My phone was less than a month old and ordered from amazon. they are going to accept the return request luckily.
I know guys, no one likes to disassemble a device or take it to a repair service center, but the issue is clearly related to a hardware fault, i.e. battery, charge flex connector or whatever they are called.

I had the same issue, wouldn't boot or display anything, so I took the phone (spesn) to a service center.
The technician told me all he did to repair the phone was a software upgrade... No problems since then, it probably can be done at home somehow...

It seems a hardware issue, but...
Some bad flashing cycle can cause the display not "turning on" at all, but really, it's just not showing a thing, to cover and check this possibility, you should flash a different firmware, just check out, the state your device gets connected, and try flashing a firmware.
For everyone who has this problem, remember that with locked bootloader it is impossible to flash the official rom by miflash.
The only alternative you have at the moment is to try to start the phone in EDL mode and that means opening the phone and seeing how to do the test point.
IF the pc recognizes it, they are in luck and it can be recovered, but due to xiaomi policies, only some people have accounts authorized to flash by EDL and charge for the service, many do it remotely and are found on telegram.
All the lot of issues, users are reporting on this device, they are realizing that Xiaomi is forcing them all to unlock the bootloader.
Unlocking the bootloader may be the fastest and cheapest way to escape from an eventual disastrous scenario.
I have the same issue with my Redmi Note 11, I successfully update it, I have 3 other chargers and cables I try all possible methods to eliminate possibilities even check type-c port but phone not charging after mini 13.0.12 update. How we gonna have fix this or is the are a plan from xiaomi to have solution?
