[Q] Xperia Z Ultra Bricked; in low-charging mode without battery connected? - Sony Xperia Z Ultra

My Z Ultra has been bricked, and I've been trying a bunch of things to restore it. But all I've been getting is a red light when it's plugged in; there's no response from pressing buttons (or keeping them pressed). I think that that means it's in low-charging mode?
Now I've recently seen this guide, which basically suggests to disconnect the battery and then retry. However, when I disconnect the battery and plug it in, the Z Ultra just gets the constant red light again (low-charging mode?) instead of flashing, and reconnecting it doesn't make a difference or boot it in charging mode.
Is my Z Ultra permanently bricked?
Thanks in advance for any help!

[Q] Boot looping Z2 wont turn on or go into recovery mode.

Hi, I think i have a unique problem with my phone. I dropped my Sony xperia Z2 from knee height and now it will not turn on. The battery was on 70% when i dropped it.
If i try to boot it into recovery or download mode, it doesn't work either, it just doesn't power on.
Now the odd thing is, when i connect a charger to the phone, the notification light turns on and flashes a red color. The phone turns on very briefly displaying the Sony Xperia Logo before turning back off again and this happens repeatedly. This leads me to believe that the issue is to do with the software and not the hardware. If this is the case then i feel as though the problem can be fixed without having to open the phone.
Do you guys have any idea what the problem is? or what can be done/tried to fix it?
Just to add, i tried to push the red reset button down which is located next to the sim card holder. This achieved nothing.
Any Help is much appreciated.
Thanks
Hold the reset keys till it vibrates 3 times
Volume up + power
Or red key under the left flap
Once this is done try powering on your device and it fails to work then flash a FTF or try to
If this fails then you have done some damage to your device hardware and you need to contact a repair centre

[Q] Xperia Z2 failed to turn on shows redlight (only when charging)

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] Xperia Z2: Red LED while charging, will not turn on

hello! sorry, i'm completely new with this kind of stuff so please bare with me ;_;
i've recently dropped my xperia z2 phone into water and it won't turn on. charging the phone only shows a red LED and disappears once disconnected. the battery shouldn't be flat since it was 80-90% when dropped. i've tried holding the power button + volume up, which made the phone vibrate (three times i think?), but no longer does anything when power+volume up is pressed. when plugged into a computer, it says the usb device has been installed correctly, but it still does not read.
i feel there's not much that can be done, but i've put the phone in some rice for several hours now praying. is there still hope for me? ;__;

Xperia Tab Z (SGP311) BRICKED

Hey all,
So my brother just gave me his Xperia Tab Z which he says he accidentally bricked whilst trying to flash firmware/root/unlock bootloader.
I've tried everything I can to try and fix it but I'm not lost.
Here are some facts:
The screen does NOT turn on at all.
The tablet shows a constant red light when connected to a power source
When I hold the power button, it shows 3 red blinks.
I left the tablet in the charger overnight.
If anyone can figure out, I'll be very grateful.
thanks,
Jay

sony xperia z ultra charges and pc recognizes it but won't turn on

hello!!! i am having a problem with my z ultra. i left it last night to charge (turned off) and today morning wouldn't turn on. i have never rooted it, custom rom/recovery etc, just stock. when i plug it in the wall charger the led is green as it is fully charged and when i plug it in the pc it recognizes it (i hear the sound) but no matter the key combination or the small red button that resets it i can't get it to power on. the only things i have tried are all the buttons combination and i needed some help from more experianced members before i proceed to other action. it is off warranty by the way.
thank you very much in advance!!
Are you seeing the LED blink when you turn it on?
Sounds like a dead screen to me....
