[Q] Z3 in sleep of death after flashing recovery? - Xperia Z3 Q&A, Help & Troubleshooting

Hi all,
I flashed TWRP recovery succesfully after unlocking my bootloader, unfortunately after flashing a newer version the phone entered a death sleep state.
I'm unable to get it working again, nothing... fastboot etc, tried everything.
Any ideas or things left that I could try?
Regards,
Niek

It was not showing any led at all, but after a night of charging the red light starts blinking. Different patterns, first a small pause, 3 blinks, and a small pause.
No i've attached it to the pc and it is blinking red, at around 50% brightness, a pause, and then red led at 100% brightness.... the pc is constantly making a sound that it is connected and disconnected.
When attached to the wall charger again the red led is blinking at a normal pattern, on off at the same brightness.
Tried everything, holding different buttons, sony repair tool....

I'm assuming you used the reset button on the side (next to where the nano sim goes).
Have you tried to force the device to flash mode? I mean, use flash tool to apply an ftf firmware?

Yes I used the reset button and also tried to force it into flash mode, flashtool recognises a device connecting but it disconnects 1 second after that and connects again.

Have you solve your problem?

[Q] Please help my sony won't boot up

I'm using sony xperia V and after flashing a cyanogenmod rom which installed perfectly, until I select reboot and the screen
turns black and no matter which button combination or whatsoever I can't boot up.
The only things that happen is:
if unplugged, pressing the power button will vibrate the phone and green LED flash for a second
if plugged into computer the green LED flashes for a long time. Holding the volume+ button before plugging in will flash a blue LED light for some time
Both plugged and unplugged, the screen shows nothing at all, which means can't enter recovery mode, safe mode or download mode.
Is there anyway I can solve this? Or I can only buy a new phone or act dumb at the sony store.
Thanks in advance and sorry for any trouble
[Edit]I finally found a way to solve this problem after hours of frustration. Thanks to this amazing website which I couldn't post it here due to being a new member, which I could say it's from a website named androidgadgetmatic, really turned a completely useless brick into a perfectly working phone again. The only problem left (which happened before bricked) is that my phone couldn't read or even find SD card, any help in this area guys?

Unable to start phone

Hello,
I charged my phone overnight. In the morning it started to boot, then totally locked up and switched off (whilst showing the Android booting screen).
I held down the power key and volume up. Phone vibrated and then the LEDS changed from green, red, blue.
Tried to re-flash the device via the Sony Bridge application on my Mac. Nothing.
Any ideas?

Xperia Tipo possibly dead?

Hi,
So yesterday I dropped my Tipo, nothing major, dropped it many times before with no issues, the screen stopped working - all lights worked and the phone itself was fine, just the screen remained black. Disassembled the phone and checked connectors etc, no issues from what I could see. I decided as a last ditch attempt to try and flash it back to stock using Flashtool, flashed it with ST21i Tipo_11.0.A.0.16_UK_Generic.ftf, completed with no issues. Disconnected phone and the LED indicator was green, nothing else happened on the phone - it wouldn't turn on etc. Decided to try flashing it again however when starting up Flashtool I noticed the previous ROM used although titled for a Tipo within Flashtool it was listed as ST26i where a Tipo is an ST21i, now everytime I connect the phone to the PC it starts in MTP mode and i'm unable to flash again or do anything, plus I can't enable debugging as the phone doesn't turn on. I've also tried using Xperia Companion however that doesn't pick it up at all.
Anyone got any ideas of what I could try next?
Update
Okay just an update, left the phone and the battery died. When trying to turn it on the red led flashed - usual battery dead indicator. So I decided to try charging it, pressed the volume buttons etc and noticed the green led come on. So managed to flash it again with the correct firmware. It seems to have done something as now when it's plugged in to charge it doesn't boot up but just shows the green led, if I press the volume up button when plugging it in the led will go blue. Anyone know what I can try now? As it seems to just boot into flash mode (green led) when turning it on and nothing else.

Is it bricked or just battery

So the Xperia z3 will not start and it seems that it doesn`t charge, furhther it wont turn on.
Tried VOL+\- + Power button and the little button behind the SIM-Cover - no reaction
When I connect it with a (working) charging unit the LED will light up red and the display shows a battery-symbol filled red on the bottom (10%)for a few seconds, then it turns off and shows the same things (led and screeen). Well it is some kind of loop. I charged it for over 24 hours with different charging devices (up to >2A)
When I connect it to a PC the LED is dark blue. PC Companion says that the phone is locked and I schould unlock it, which is impossible as I am not able to turn the device on
Connecting it to the PC while holding the VOl- the PC Companion can do a software-repair and it says it works, but it doesn`t change the behavior of the phone.
I once got hands on an old Z3 wich showed the same behavior, it was just the battery. I changed the battery and it is now working fine again.
