S6 won't turn on, solid blue led light - Galaxy S6 Q&A, Help & Troubleshooting

Hi,
A friend of mine gave me his Samsung Galaxy S6 because he knows I know a bit of smartphone repair. (I have installed a lot of custom roms, replaced screens, batteries, ...)
But I can't seem to solve his issue.
After charging at night, he wanted to power on his phone, and it wouldn't turn on. Only the led shows a blue light. It's impossible to turn the phone off, only by removing the battery.
I tried every option I could find
- Volume up + power button = same as just powering up, only the blue led light
- Volume down + power button = does nothing
- Volume up + home + power button = does nothing
I held every combination for over a minute.
I even tried to connect it to my PC and to get to it using adb commands. but my PC can't find the device.
I used a backup screen to make sure it wasn't just the screen that was broken, and this screen worked perfect on another Samsung S6.
My friend already has a new phone, but there are some pictures on this S6 that have some emotional value to him (pictures of deceased pets for example)
Does anyone have any idea what options I got left?
Or is this phone completely dead?
Thanks in advance

Strange. Seems like you have a damaged partition. Do you see a boot logo when powering on?
e.g.

Galaxy S6 (edge)

Let's start with the simplest.
I hope you tried to:
(1) completely turn off
(2) press and hold vol down + home + pwr.
As you can't get into recovery/download mode, why not try a simple usb jig made with a resistor? This method will turn your phone into download mode again. You may want to use odin to flash a custom recovery and then backup your data.
Here is a short clip on how to use jig:

Soldering and recovering data stored on the nand chip can be a dangerous undertaking. It's advisable to take your phone to a data recovery specialist if needed.
Good luck

Thanks.
I indeed tried to power off the Phonehouse and using the "hold vol down + home + pwr".
I ordered a USB jig on eBay (I'm not the best in soldering, don't have a steady hand).
I'll try it, and hope it works.

[Q] Kolina K100+ dead - help needed

Hello,
[admin; if this post is more appropriately placed somewhere else in the forum, then please move it]
Before giving up on my cellphone and resort to ordering a new one I'll ask for help here too.
Phone is a Kolina K100+ (chinese phone) running android 4.2. It is rooted but it is still running stock ROM (to my knowledge, I bought it new and have not tinkered with the ROM).
Current situation is that the phone is completely dead.
Dead as in turned off, does not light the LED when inserting the charger cable, does not react to any button presses, or combination of button presses.
I have actually no idea what have caused this situation. Granted, the phone has accidentially been dropped twice the last week but it did not turn itself off at any of the occasions. Yesterday, I noticed that the phone had turned off and I tried to turn it on. After a while I got it to go at least to the boot screen but after having to put it away (was actually standing in a line and it was my turn...) it was dead when I was able to reach for it again and after that the phone has been completely dead.
When connecting the USB cable to the computer the computer detects an unknown USB device but cannot seem to install any drivers.
Button combinations I have tried;
- power on button
- long press (~1minute) on power button
- volume down + power button
- volume up + power button
- volume up + volume down + power button
- home button (touchscreen button that is) + power button
...no luck with either combination, no reaction at all from the phone.
I have also managed to pull off the back cover from the phone and was able to disconnect the battery connector and let it lay completely powerless for a few hours before reconnect the battery to the phone and reassemble the back cover.
Any suggestions on if there are any other measures I can do or if there is something I have overlooked in trying to resurrect it?

Power button broken. Turn on device

Hello.
My power button is broken. The only way I know to turn the phone on is removing the battery and connecting it quickly. I could get into the stock recovery pressing vol + and connecting to the charger but I need the power button to select any option, I installed TWRP recovery but I cannot use it, the button combination is different to get into (vol + & power button).
Is there any other way to turn on or use recovery when the phone is off?
Thanks
Fastbooting it from the computer is a solution..
Fastboot is disabled in android marshmallow. Now, how can we boot the phone ?
One last resort option is to send it to Alcatel. I had issues with my power button failing and they resolved it. (FTR I was still under warranty)
I had this problem. Eventually found a video for it on YouTube. I couldn't return my phone to Alcatel as I had dropped it in the toilet ? and then taken it apart to dry it out.
If its still under warranty I would return it to Alcatel. If not then the way to turn it on is a bit of a pain at first but quite easy when you've done it a few times. You do have to take the back off your phone.
If you are happy there is a reasonable amount of charge already in it then plug it in to a charger whilst holding the volume up button (or down button I forget which!) This should start the phone in the recovery mode.
Then unplug the phone.
Then very quickly disconnect and reconnect the battery.
Phone will turn on.
Put phone back together.
Keep battery charged!

G Pro 2 ... Wrong Flashing. Pls Help.

I have a Lg G Pro 2. Few days back it got bricked by its own( a crazy fact). That time it was showing QHSUSB_BULK. I figured it out as 9006. Took the phone to a local service shop. Today I got it back and found that nothing had happened to the phone, except worse. Now it is not detected by PC, only green light blinks for some time if tried to power on. And then everything is black and cold as death.
I think it have been flashed with wrong ROM. Anybody here can guide me with the test points of Lg G Pro 2 (D838 F350) ? So that I can force it to QHSUSB_BULK ? Or any step by step advice to get it up ?
I am in real need of assistance, and thanks in advance for any sort of help. Best Regards.
I would like to mention that the phone indicator blinks for sometime if I try to power it on, as it does on boot, but nothing else is there. No recognition by PC, no presence in Device Manager. Blinks for sometime, stops, again starts blinking... and this goes on at regular short intervals. The area around the camera gets warm after sometime. Everything loops till I pull off battery.
Now, am I missing something ? Is the problem not as deadly as I am thinking ? Is it soft bricked ?
Hi, I not sure how it got bricked I never brick LG device.
Normally if anything happen we try pull battery out and put it back in, try then to turn the phone on.
Have you try connect to to pc with USB cable, one end of USB connnect to pc and other end connect to the phone. Then try press Power + Volume Up or Power + Volume down, this is to try to get into phone download mode. If you can get into download mode you can flash the kdz file to make it useable again.
Or without the USB cable we want to get to factory reset mode by use hardware method try press:
- Power + Volume Up or Power + Volume down
- If you see LG logo come up release the buttons you press above 1-2 second
- Press again Power + Volume Up or Power + Volume down
- Until it show and ask to use volume up/down button to select choice, say yes
Caution factory reset will delete all data on the phone and reset it as when you bought it new.
- Again it will ask for factory reset, use Volume up/down to choose and select yes for factory reset
turn on the phone and when light is blink press volume up or down button for some time and see if it it is detected as usbhulq?

Galaxy s6, boot loop from HELL

Please help me! I own a galaxy s6 (international model, official, not rooted) which is stuck in a boot loop from hell. The led is white (not the usual "boot-up blue") and won't change colour or even turn off. It was the last straw a few hours ago when it randomly restarted, got stuck halfway through the Samsung logo and started making the loudest noise I've ever heard it produce. It was NOT a vibration. Ever since then, it has just been stuck and keeps restarting. When it does get past the "Samsung Galaxy S6" screen it just says 'no command' with the android lying on its back. I'm at a complete and utter loss. It's actually done this a few times this week, but I've always been able to at least boot it into safe mode and uninstall snapchat - which I think is the cause of all this. I can't power off the device, and even when the battery drains completely, the same 'no command' screen appears as soon as it's plugged in. I can't boot it in recovery mode as I can't get it to switch off. I think it may be battery related or even motherboard related. I can't even seem to bypass the 'no command screen. It's just sitting on my floor, charging, overheating and looking all smug. Frankly, I'm pretty damn close to hurling it out of my window.
Also, does anyone know WHY the led is sometimes white or yellow during a boot loop on newer Samsung Phones?
Put the phone in download mode by holding Power + Home + Volume Down buttons. Plug in to Odin and Flash Official Firmware or use SmartSwitch

Thanks but I've tried this several times. The device seems to be completely unresponsive to all commands except a force restart (power key and volume down). I can't put it in download mode or even power it off
have u tried using smart switch emergency firmware recovery? power key and volume down should force it to power down, than enter download mode vol down + home + power key.

if you are not be able to take your phone to download mode then repair center is the only solution.

Samsung S8+ (SM-G955UZKATMB) Boot error / "Upload Mode - Unkown Error"

A friend of mine tried to root his S8+ from T-Mobile while following random instructions on the Internet and got his phone into this weird boot screen, which I must say I have never seen before.
Note: I have tried many times to enter to download mode by using the power button, bixy, vol- combination to no avail. When I turn the phone off and plug it in into the computer it gets recognized as QUSB_BULK.

I was wondering if any of you have had similar experiencies or perhaps even help me find a solution. Thank you in advance for your assistance.
This isn't anything out of the norm and has been covered more times to count. Get back into Download mode and finish the process.
Thank you for your answer and thank you for pointing out that I should have said that I've tried countless times to enter download mode by pressing vol- + power button and then power + vol- + bixby to no avail.
The only way to get the phone to boot into something is to press all buttons together while waiting around 10 seconds which, gets me to the screen in the picture.
Is there another way to enter download mode apart from using the regular bixy + vol - + power button combination?
hold down vol- and power only. when it resets, immediately keep trying bixby vol- and power. also if the phone is in a case take it out.
i think you have a fake s8+
It doesn't work, it gets detected as QUSB_BULK every time, only if I press all buttons does it give me a screen which is the one posted.
This is a genuine S8+ from T-mobile, I've made sure of it!
This happened to me
This is the worst, after giving up thinking my phone was bricked I just let it run out of battery. After it was dead i held volume down + power + bixby while plugging in a charger and to my suprise it went into download mode. I tried again and again to confirm it worked and it worked every time. So you just have to wait till the phones completely dead, and hold those 3 buttons while plugging it in to a charger.
Thank you for your answer, I did try that but it didn't work for me... no download mode, just that upload mode - unknown error...
I have the same issue plz help
Yup I've seen that same screen you're referring to on my S8+ Tmobile. It's tricky but you can make it work. Change the way you try to hold that combination of buttons. As previous answers mentioned, you have to be quick.
Here is what worked for me:
I plugged the phone into the computer, using the original USB cable.
Hold "PWR"+"BXB"+"VOLUP" until you see the phone's screen blacking out completely. Then IMMEDIATELY hold "PWR"+"VOLDN" and keep holding. That should put you back into Download Mode.
Again, it'a bit tricky so keep trying and checking your technique but you should eventually get it.
I've seen that issue before where no button combination gets you out the QUSB_BULK mode. I'm afraid it's a corrupted bootloader (aboot), which can only be fixed using a special "Dead-Boot" package, which uses a QComm low level loader (not download mode). You can search for it, but it's pretty hard to get since it's specifically written for each model. Here's a package available on a pay site https://combinefile.com/index.php?a=downloads&b=file&id=32731
