Stuck in Flash Mode after battery drained overnight - Xperia Z4/Z3+ Q&A, Help & Troubleshooting

Hi
my phone wont boot at all. Connecting to charger gives continuous red flashing LED. Tried different key combos to reset/reboot. Nothing helped.
When i connect my phone to PC, Flashtool show phone in flash mode. Have also tried flashing different kernel and recovery from fastboot mode, but that is also not working.
Any help is appreciated.
Thanks

I Just flashed .253 firmware and it works now. maybe OTA messed up? Can someone confirm this?

What you mean nothing!
can boot even to fastboot?
if can access to fastboot so flash the recovery and then everything you want through recovery...

Nothing....it just died. no lights, no vibrations, no nothing...I have tried all the combos with the vol buttons and the power.
I think I'm in the same boat. Flashed the latest PA then reboot just stayed on black screen. Holding power causes short vibrate every couple of seconds. Connected to PC and able to boot into fastboot mode. Is my best recovery method to just flash the latest ftf?
Its most likely a kernel issue. Flash the kernal you need for that rom
is it ok in mode flashtool ? (vol- , power, plug in) if yes flash an official rom ftf by flashtool
try holding VOL+ and Power button for 10 sec then try entering fastboot or flashmode
same problem but my xperia vibrates but not open

Red Light can't charge or boot

BootLoader has never been unlocked.
Phone has never been rooted.
It was on Career Stock firmware, last KitKat update.
The phone was at 70% Battery, then power off itself. I tried to power on but the Red LED was blinking, then tried to charge it but it did the same thing.
Finnaly I tried to connect to PC, i got sounds notifications that it plugs in and out, Like the phone was powering off and on.
Does anyone know if it's possible to acces internal storage , and if it's possible to repair the device?
Thanks a lot for answers.
You can flash the Firmware again with flashtool...
The Phone doesn't stay connected and can't boot. How can i flash firmware this way?

Prepare the files in flashtool then when the flash tool tells you to connect the phone hold volume up and connect the phone to pc . If the flashing is started then the phone will stay connected until the end of flashing . I had this problem .

flashing issue (help)

hello,
have a c5303 xperia sp and im trying to re-flash the stock rom using flashtool64. the phone doesnt power on but if i hold vol up/down then plug the phone into my pc via usb the respective fastboot/flash mode led colour lights up and it pops up on my computer to confirm it. when i try flash the stock rom, is gives me a error about system.sin, since then i am not able to get into flash/fastboot modes on my phone. as this has happened before (the phone not going into fastboot) im pretty sure i can get it to flash without system.sin then use fastboot to do it after.
the screen is completely blank, not even a backlight. when the usb is plugged in without a mode, it is red on the phones led, when i unplug it and try to turn it on, the red led flashes and nothing happens.
thanks in advance!
fixed it nvm

Unable to flash any ROMs?

So after some confusion, I managed to get my Z1 rooted and got the dual CWM/TWRP recovery installed. However, I've tried flashing several ROMs in TWRP, but when I reboot, the phone won't start up. It will just vibrate when I push the power button. If I plug it in my PC , the LED will flash red. If hold the volume down and plug it in, it'll go to flashmode. If I hold in volume up and plug it in, it'll go to fastboot. But that's all I can do. It won't boot the ROM that I flashed and I can't get into recovery. The only way to fix this, is to boot into flashmode and use the flash tool to flash the .108 ftf file.
Please help. Why aren't any ROMs booting? What am I doing wrong.
EDIT: I am really at the end with this phone. Nothing but frustration. Someone please help, I've spent hours and tried so many different combinations of flashing in CWM and in TWRP. I've tried multiple times to flash with fastboot. I've tried everything I can possibly think of, the phone's bootloader is unlocked. Just every single custom ROM and kernel combo will simply refuse to boot.
