[Q] Xperia Z2 failed to turn on shows redlight (only when charging) - Xperia Z2 Q&A, Help & Troubleshooting

When I connect my xperia z2 to the charger, it shows the red light like its charging then after a couple of minutes shows the sony logo and shows the battery icon then then the red light goes off and sequence continues. The phone is driving me nuts. I've tried using flash tool but the phone cant even get into flashmode, it gets into fastboot mode though but thats about it. I've tried different chargers but failed.

Leave it to charge
My device faced this a few times but eventualy it got into charging mode and i was able to bring it back

[Q] Charge/Startup Problem

Hi There,
I had put my phone on charge the other night, everything was fine and it was happily charging away. I wakeup in the morning and see a notification on my phone. I unplug my phone the battery then shows 1% and turns off. I then did the smart thing of removing the battery for 5 seconds, putting it back in, turning it on and it turnt on but with 0%. I then put the phone back on charge.
This is where it gets interesting yet annoying. The phone flashes a red light whilst charging, it then goes to boot up showing the sony ericsson logo and then just turns off and repeats itself. I have had the phone on "charge" for an hour but to no avail of anything working. I am unable to connect via usb as the port to re-flash the phone as when it was repaired for some reason it has never connected via usb again.
Any help would be greatly appreciated.

X10 Wont start, Not recognized on pc. Can use Bootmode in wall socket

Hi everyone,
Some time ago my Xperia X10 suddenly got some error messages and i decided to just remove the battery and repalce it.
After i did this the phone wouldnt go further than the Sony Ericsson logo, so i pulled out the battery again.
After some time it wouldnt start up at all anymore.
I actually gave up hope untill a few days pack i decided to try connecting it to the pc once more.
when i tried to start in in boot mode (back button + connecting the usb) a red led started blinking with a 1 second interval.
So i tought if the led blinks there is life in it and i can fix it.
I fooled around with it a bit (note that my pc never really found the phone) and tried charging it in the wall socket.
When i try to start boot mode while connecting it to a wall socket a green led starts burning.
So i tought it might have been the battery, i ordered a new one wich came in today.
Sadly no help since the green light imediatly shuts down if i put in the battery wich has been charging for about 5 hours now.
Can anyone please tell me whats going on and if its fixable?
If you need anyomore info please ask because im sure i forgot some important stuff.
Thanks in advance.

I'm just trying out some more and found that:
-its not boot mode but just the green charging light comming up when i connect the phone to a wall socket without a battery
-there is no green light (so no charging?) when there is a battery in the phone
-with or without battery there is no green light when i connect it to my pc's usb (not enough power supplied?)

Xperia p hard bricked

First of all i'm a noob and my english is not good.My xperia p (jb) is now dead. When i connect charger it shows red light for 3-4 second then turn in to green led and phone screen starts and goes off and its continuesly duing for hrs.
Phone was rooted by kingroot. Accidently run an uncompatible app of lg to unlock bootloader. It was completed all fine bt when i restarted the phone it was dead.
Although my phone was responding in key combination when its battory working and my pc also detecting the phone. But now battory is not charging.

Check if you can connect the phone in flashmode.

Xiaomi Mi Max 2 Not Booting Up

Hi all, So the phone does not turn on or show any sign of life while unplugged, not even the notification led lights up.
- When i plug it in, the "mi" logo appears for a second and then it turns off.
- When i try booting it into recovery mode (while plugged in), the "mi" logo appears, phone vibrates and then it turns off.
- When i try entering fastboot while plugged into the outlet, fastboot appears for a second, screen goes black but the notification led keeps blinking.
- When i try entering fastboot while connected to the PC, fastboot screen appears for at least 30 seconds, USB malfunctions and the device is not recognized (Trying MiFlash tool latest version.)
- I also tried using several other chargers and a power bank, It usually draws power for a minute or so as though it's charging and then it stops.
The cause of this issue is most likely water damage (The phone is in a pristine condition, never been dropped or mechanically damaged).
So what could be wrong with the phone and what could i do to fix it?
Any thoughts or comments are appreciated.
