How I "fixed" a "brick" on Xperia SL

Hello,
I'm a new user and this is my first post here. I felt the need to "contribute" with my somewhat of a unique case.
I bought the Xperia SL 48h ago, and managed to "brick" it. The phone just died on me during regular use, I was in astro manager at the moment of the brick, the screen gradually turned off, and the phone became unresponsive soon afterwards. It didn't react when I plugged in the charger or when I connected it to my pc, the LED was dead, power + vol up button combo was also useless, and the pc saw my device as "QHSUSB_DLOAD".
I managed to solve this issue by holding power + vol up button combination for four (4!) minutes. I didn't really have a stopwatch, but I was in the bus on road to the store to return the phone, and just thought I might give persistence and stubbornness a chance. Three bus stops later, the phone vibrates and just turns on normally, like nothing happened.
I don't know how bugs like this occur, nor do I know how to prevent them; I am going to pretend this was just a work of gremlins.
Bottom line - if power on + vol up button combo didn't work for you for a 5 second, 10 second or a 30 second time-span, hold them buttons for a couple of minutes and pray that it works. I hope this helps someone.
Best regards

Did it have enough charge?

Seems your phone got stuck and turned the screen off.
Holding power+volume Up forces it to shutdown without messing with the battery-removal.
So you might have been able to restart it successfully.

The battery was at 14% at the time of power+vol up wake up. I didn't charge it though, I plugged in the charger just to see if there was a LED on, but there wasn't any LED response whatsoever.

That must be it. At the moment of the brick, screen gradually turned off, with darker colors becoming instantly black, and brigther colors getting a yellow tint just before everything vanished from the screen. Thing is though, the phone didn't react to the power+vol up combo right away, but two hours later and almost four minutes of holding the buttons.
One more thing that I noticed was, when the phone was connected to my pc, if I held the power+vol up, the pc would add/remove my hardware in a cycle, or at least play the sound of a device connected/disconnected. The phone still remained dead, but returned later for a miraculous wake up.

I'm not an expert, but this is probably your phone entering fastboot mode and then being disconnected due to incorrect drivers on the PC.
Glad your phone came back though. Comatose phones are terrifying, no?

I'm not out of the woods yet.
Got myself a second brick, and I've been trying to work it out for the past 24+ hours. I won't post about it on this thread, I've posted here: http://forum.xda-developers.com/showpost.php?p=39847797&postcount=532 , but I will report back with any advancements on the matter.

Phone just stopped turning on..

well...this kinda ruined my night yesterday...I went to a concert yesterday around 8 and my phone had 70% and I was checking facebook or something like that and without no notification or warning it froze and turned off on me. I figured it was a normal freeze..and I attempted to turn it back on and nothing happened. Went to my car to try to charge it and nothing. Not even a charging light. A day has passed after the concert was over (could not take pictures, thanks htc..) and now the "dead battery symbol" comes up and the orange light keeps BLINKING..to my understanding it means that it is not charging? What could it be..anybody could help me out .maybe a soft reset? no charging it for a couple of minutes?
Anything would help. Thanks

Try pressing and holding power and volume up?

I'm sure you've already tried that, but can you confirm that you have left it plugged in atleast for 5 hours continuously after this happened.

And hold the power and volume buttons down in a well lit environment, there's a "pocket check".

You can also try by hold the power and volume buttons UP

Thanks for the replies , i have tried those opctions. Holding the power and volume UP and thencanother try wih the DOWN the with both. It just blinks orange now. I just woke up and plugged it in again, am going to work and going to leave it like that, hopefully that does the trick. Should i call htc ? It hasnt even been a month since the phones came out.. I did not do anything to "kill" the battery

Ofcourse you may call Htc.

the same happened to me now.did u find a solution?????

Have you got delvolper options enabled, if so when connected to your computer you could try Adb reboot or Adb reboot bootloader

Well only thing I can suggest is you leave it on charge over night. Then try & power it on if no go try and hold the volume up and power button while plugged in for at least a minute if that Dosent work take it back where you got it from.

Unplug phone. Hold vol up and power for 10 seconds, let go, try to power on phone.

[Q] SKY BLUE more like SKY DONE! PHONE WONT BOOT

Hey dudes, check it out bruhs my phone is kinda acting up.
The story goes one day i was using my phone while it was charging, then it turned off and i thought maybe the battery is low. I left it charging overnight thinking it was the battery only but sadly it wasn't. I tried to boot it and failed. Now every time i try to turn on my phone it will shut off by itself. As soon as i put the battery on my phone it automatically boots without pressing any button and shuts off after a couple of seconds. (I've tried a different battery no luck still) Any help would be
much appreciated thanks a lot!:crying:

Can you enter Download Mode?
"Press and hold Volume Down, Home and Power buttons, all at the same time."

Phone not turning on.

Hi. So after a long wait I got my Zenfone 2 ZE551ML today. The first thing I did was turning it on and it turned on normally, then I proceeded to make the initial setup (logging into google account, etc) without any problems. Then after about 10 minutes of use the phone suddenly turned off with the battery being at around 35% and didn't want to turn on again. I read that old firmware (like the one that comes default with the phone) had battery display errors so I thought the phone had run out of battery, so I charged it for 8 full hours and I unplugged it now. To my surprise the phone is not turning on either. The only way I can make the screen show something is by connecting it to the charger, it vibrates and displays a white battery icon, eventually changing to fully green (fully charged battery, the green led indicator also appears) only to disappear like 3 seconds after. Can't turn the phone on while charged and can't even make the phone show the battery icon again (unless I unplug and plug again, repeating the cycle). So, what can I do to turn it on?
Thanks in advance.

I have a feeling that you did not hold the power button long enough. Disconnect the charger first, and wait for about 10 seconds. Then, hold the power button for at least 6 seconds. The phone should then vibrate and then you may release the power button. Other reasons why your phone may not seem to be turning on at all might be due to the back cover not being fully locked in, thus not making any contact with the power on the motherboard itself.
Do report back the results.

I did. Doesn't work. I also removed the back cover and pressed the power button with nails with no results either. Personally I think there's something to do with the power button as it doesn't even responds while charging (pressing it should display the battery icon) and the only time I could use the phone it didn't work to wake up the phone or setting it to sleep, only double tapping worked. What is strange is that it worked the first time I turned on the phone though.

Are you able to get into FastBoot mode? If so please try performing a hardware reset including wipe cache partition. Please see the following:

One Plus-3 Black Screen. No LED No Vibration. Hardbricked?

So I had kept my oneplus3 on charge at around 10:00 Pm yesterday and fell asleep. Woke up around 12:00pm to see it was fully charged so I unplugged the charger kept the phone beside me and went to sleep. Today when I woke up I saw that the phone has a black screen and is completely dead. The LED light is not on. Plugged into the charger no response. Tried holding power button ..nothing. No vibrations or home button lights
Currently, there is nothing going on with the phone. No flashes on screen no LED. Absolutely nothing. Tried connecting to laptop (windows 10) dont see anything. It was working perfectly fine last night and i had used it for nothing but music then.
Question is.. is the phone hard bricked or completley bricked? what might be the reason? I searched youtube only to find 1 person with similar problem who had said that he kept the phone for 48 hours and when it was completely discharged he pluged in charger again and it started working.
I am confused. Have a lot of work documents inside and what if it stays the same after 48 hours?
Appreciate any help on the matter
update: Tried plugging in the charger a few min ago. The led turns red and Vibrates. Nothing else
Update 2: so after 24 hours of setting the phone aside. i plugged the charger and it went into charging. But now am facing a new problem. My bootloader is unlocked and the power button is busted hence whenever I press volume down and plug-in the charger it takes me to bootloader warning screen from where either it goes into charge or i press volume key and it goes into option which I again cant select cause power button is busted. Tried holding down the power button and connect to laptop(windows 10) no device detected and it works like normal charging. Tried to charge for a few minutes unpluged charger and start again .. it was stuck on oneplus screen. Any ideas??
