bricked phone and no clue what to do - Xperia Z3 Compact Q&A, Help & Troubleshooting

got an broken D5803 and hoping to fix it with your help.
(i have no clue what happend to the phone so far)
if i power it on, the notification led is red the sony and xperia sign shows on the screen, but after a short time it restarts.
i can turn it into flahsmode and fastboot mode also.
if i turn it into flash mode and try to flash a firmware with flashtool it goes through the process. but when it restarts, nothing have changed. even the version number havent changed in emma or in flashtool.
any bets what it could be?
i am almost shure its an hardware defect. most propably the main board. but i ask myself what exactly could be broken?!
thanks in advanced for any help.
and sorry for my bad english
oh, and i do tried to search for the same problem and had no success to find the same problem.
EDIT: something new happend. i tried the repair function in the pc companion. flashed again. after restart the battery symbol showed up. battery level low and red. but when i connect it to my charger. the "bootloop" restarts...

I had a similar problem.
My phone went to the bootlogo (blue waves) and started to buzz for five till ten seconds and went to a restart (bootloop).
I am not sure, why that happened, but I think, it was because of a russian firmware (downgrade to Android 4.4.4 for flashing a custom recovery and root).
At first, try to fully recharge your battery (recommended for a firmware flash).
If your phone restarts into bootloop after you connect your charger cable, try to hold the power button until you feel a three-times-vibration. Now your phone should be absolutely powered off.
Download following firmware to your computer: "D5803_23.0.A.2.93_Generic_GLOBAL_1286-9917" (http://forum.xda-developers.com/showpost.php?p=56138053&postcount=27 or http://forum.xda-developers.com/showpost.php?p=58418863&postcount=358)
If your phone is fully recharged, open flashtool and load that firmware into the flashtool.
The system will now ask you to connect your phone in flash mode with your pc.
Now connect your phone with your pc in flash mode.
I am not sure, but flashtool is asking you a question after the flash mode is recognized. I answered with No.
The flashtool should now install the Android 4.4.4 firmware to your phone.
I hope the steps above may help you.

[Q] Can't flash & maybe (soft?)bricked

Hello. I've had an X8 for a while, and I got tired of the MiniCM9 and wanted to go back to Eclair. So I downloaded an original firmware (my backups are lost in a damaged computer), got the last Flashtool and installed the " X8i_2.1.1.A.0.6_Baseband_015.ftf " to my phone. But, now it only loads the Sony Ericsson screen and nothing else. I tried to flash it again several times, but I don't seem to be able to get into flash mode. I press the Back button while connecting, but nothing happens (until I release it, which is when the SE logo loads).
My phone is still responding to the charger and charging the battery with USB, but I can't do anything else.
try repairing using pcc or seus.

Both PC Companion and SEUS require me to press Back while connecting USB (flash) to proceed.

Follow the steps from here. Also download the correct .ftf file(2.1.1.A.0.6), not the baseband ftf file.

Xperia T - Bricked?

Hi guys,
I have an old Xperia T which was in the middle of being flashed with a 4.3 based firmware but there was a problem with the install. I didn't care too much at the time because i already had a new phone, but now I'm trying to get it working again as a possible backup.
My problem with it now is that when i switch it on, it will display the Sony logo and then the screen goes black, apparently freezing. I have tried to charge it overnight but the light always stays red, never goes green. When i try to connect via my laptop (Windows 8.1) i can't get the laptop to read the phone, the USB will bring up the red light on the phone and the phone will even boot to the Sony logo but then....well, nothing. I have also tried booting into recovery but again nothing.
I'm not expecting a wonder fix, i think the phone is maybe bricked but at the same time i haven't the most knowledge on these matters. I have Googled various sites that have similar problems with different models and each one seems to be fixed with the Sony PC Companion - but like i said, my laptop doesn't even recognise there's a device plugged in.
If anyone has any suggestions it'd be appreciated, but like i said, i don't expect to find a cure, just hoping i can say i haven't bricked a phone like a n00b
Thanks for your time
Dude ... relax.
If the phone still shows the SONY logo, nothing is lost.
Step 1: Download Flashtool: http://www.flashtool.net/downloads.php
Step 2: Download an appropriate Firmware in the FTF format from here: http://forum.xda-developers.com/showthread.php?t=2648320
Step 3: Ensure the driver for the phone is installed and works correctly.
Step 5: In Flashtool, select the lightning "Flash device", then Flashmode. Select your folder where you store the Firmware.
Step 6: Click the flash button and turn off your phone. If you connect it via USB to your PC, press immediately POWER + VOLUME DOWN. The notification LED turns green and the flash process begins.

phone reboots everytime i flash the stock rom using flashtool

when i connect the phone(soft bricked), flashtool automatically detects that it is connected to flash mode already.
when i start flashing the stock rom, it eventually stops flashing because my phone would reboot. tried repeating the process again and again but the phone keeps rebooting.
any ideas on how can i fix this myself or do i really need to go to a technician.
TIA
tried using another usb cable because i thought mine was faulty but it turns out the cable was not the problem at all.
Hey
I expericened this problem on my old Xperia X10
First try to reinstall Flashtool and drivers.
Just one solution worked for me but idk that its works on V or not or causing damage so do it at your own risk
Pull out the battery then connect to your phone to PC then press the volume down button and hold down then put in your battery .

Can't turn on my Z3+ After Sony Logo it has black screen after nothing! Please help!!

Hi all,
I already try everything to phone turning on, and working again!
Flashed it with flashtool, the result the same.
Tried flash twrp and another boot.img in fastboot mode, but this also unsucessfully.
PC Companion say no available software for it!

Flashtool flash is okay, flashtool said unplug and turn on, but when I turned on it just appear the Sony logo, after it has black screen!
What can I do yet with it to working?

Possibly the battery died?
Because I charged it 2 hours, after I use flashtool and fastboot mode to 20-30 mins, after I want to turn on the phone, but I get the picture from low battery.
Sorry for bad English!
Did you do a full wipe? When you flashed your fw on flashtool
Yes!

Bricked my Xperia SP after flashing Cyanogenmod 13

Hi guys, this is my first time trying to flash a smartphone and i had no luck. After i press the power button nothing happens, only a small vibration and a little green led blink. :crying:
I'm trying to flash the stock ROM through Flashtool but my Xperia SP keeps disconnecting and connecting after a minute in Flash mode, the green light turn OFF for a second then ON again every minute. But if connected in Fastboot mode the device keeps connected normal but I cant select the .FTF file. I have no idea what to do now.
I bought it last year second hand its my first smartphone im broke as **** i cant believe its not working anymore. My last phone was a Nokia 5310 that i used until decomposition, literally. Sorry for bad english.
Please help.
share the instructions that you followed.
Did you root your phone and unlocked the bootloader, installed recovery ?
it is possible that your drivers are not properly installed, try using windows 7
I have similar issue but phone is not bricked it's charging really really slowly. And I don't know issue of it? If someone can link some room that don't have this issue that would be g8.
