Phone bricked after batter replacement - Honor 8 Questions & Answers

I replaced the battery myself.
After finished, I trun on the phone, it vibrates once and the screen light up a little (hardly see it) but cannot boot. When I press and hold the power button, it turns off but on again automatically with the same phenomenon. What did I do wrong? I can charge the battery (the LED changed from yellow to green).

I had this to several times after changing battery. I had to disconnect the battery and connect it again every time it happened, not so funny opening the phone up every time...
After a few times it just started to work normal. Strange.

[Q] Phone turned of and not turning on again

I Think that its the power button that is stuck but im not sure
My phone started going crazy, when I turned it on, it was going to the HTC logo and then turned off (After about 3-4 seconds, Not showing CyanogenMod logo.)
and when I managed to turn it on (Remove the sim-card and turn it on normally) it worked, and when I inserted the simcard the phone got stuck and disconnected.
I Cleaned the simcard (Rubbed it against my pants..) and the phone worked for about 30-60 minutes, not sure.
After that 30-60 minutes, i saw the screen turned on showing the lock screen, then it asked me if i want to power-off or reboot, i pressed the back key.
And the phone turned off.
Since then i cant even turn it on..
And when i plug in the power adapter, no LED going on.
so i disassembled it, And disconnected the battery, and when i connected the battery again the phone turned on as if i am pressing the power button showing the htc logo and then turning off again..
and i cant turn it on..
SORRY for the long story..
I Checked (Using a multimeter) And the problem is not withing the power button or the battery (Battery gives out 2.9 volts instead of 3.7 as written but its because low battery..)
Still the phone wont charge

Alcatel idol 3 wont turn on!

Hey i am new to this forum,so sorry if i am posting this in wrong section or smtn like that .So yesterday i was searcing the web when suddenly my screen turned completely blue!That lasted for about a second ,and then it came back to normal.After a few seconds it happened again but many times in a row.I tryed to power it up ,but on boot,it turned blue again and shut down again.It was off whole night,and at morning,it booted normaly,andbi managed to move all my data to computer.After i finished that,i tryed looking what could be the reason for this to happen.But phone shut down again.Till now i was able to turn it on for about 2-3 seconds and then again shut down.The thing that i noticed is that when phone is booting,it will warm up pritty fast,but not at some high temepratures,but that much that i can fill that it is hotter.I decided to try to put it charging,but the battery icon would appear,and after few seconds screen would be blue again,but it would charge.I also noticed that led indicator was showing charging but with low light.I decided to factory reset,oressed few buttons and screen turned off,but led indicator became much more noticable.Now it wont turn on.I tryed power cycle but it does nothing.Any solutions?My phone is alcatel idol 3 6045k with stock 5.0.2 android.
assuming your phone has a charge.
press and hold the power button till the acatel boot screen shows up.
the phone should reboot this may take 30 seconds to 1 minute to reboot.
you might see if you can get into the boot loader also.
it could be worse issues wich others here might be able to help more with.
Sounds like a hardware failure. I recommend sending it in for repair or replacement.
warranty repair...

Phone won't turn on

Hello guys, I have D6603 and tonight, phone gone dead... How it's happened... So, I was playing on phone and put phone in my pocket and stand up and phone felt from pocket and no reaction. I was thinking that display is broken.. but when try to make something, no reaction. I put it on charger (before drop it has 89% battery) and red light appear. I told WHY!? you have battery... after 10-15 sec, display light up and shows SONY, I told great, display is OK, but 1-2 sec after SONY logo, phone restart. NO VIBRATION, NO START UP, NOTHING.... when SONY logo disappear, red light gone for 5 sec, and then light up bright, after 10-15 sec red light dim and SONY logo appear, this is for 1 min and it stops, only red light... I left phone on charger, after about 30 minutes, red light turn off and nothing, phone won't turn on. I try Vol UP + power, yellow button, remove battery(when battery is not connect, it appear empty battery logo and 5 sec later phone restart, when connect battery again SONY logo for 2 sec and restart),nothing, no vibration... I try connect with PC, only fastboot work...
do the 20second reset. this simulates a battery pull.
i dropped my Z3 too, no damage at all, but it doesn't work at all anymore. No red lights nothing.

Solid white led + Black screen

Galaxy S6 SG-G920T
The battery was dying quickly, when charging it overheated the phone. She always used the phone until the battery hits 0% and it turned off. This time when she put it to charge the phone heated and it didn’t appear to be charging and the phone didn’t turned on.
She went to a phone repair center they changed the battery but the phone didn't turn on.
When I got the phone force reboot, combination didn't work until I pressed Vol Down + Home + Power for 10 seconds (I think I entered download mode) the phone led turned solid white with black screen but the phone didn't do anything I did number combinations for forced reboot and didn't work until the battery runes out and it turned off. Try to turn on the phone and it doesn’t.
Any ideas what is happening?

Phone won't turn on...kinda

On some random day i was on my pc, not aware of the fact that my Q6 had to be charged. I looked over and noticed that the battery died (the phone was in perfect condition and had never had problems before) but then when i tried charging it, it didn't turn back on.
Basically all it does now is show that it's charging, it then proceeds to try and turn on, it vibrates and the screen remains black, after about 2-5 minutes it vibrates again and again until i let the battery drain, then it just shows a battery icon with 0% on top of it.
I have tried booting into recovery or maybe plugging it into my pc but nothing worked, has anyone had experience with this and knows how to fix this?
