I tryed to wipe data/factory defaults and cache so far from boot recovery menu.The other options didnt work.
>Tried so far stock roms A536_S175_150105_ROW
, A536_S147_140910_ROW with Smart Phone Flash Tool a
nd Sp Flash Tool without any luck.Also Installed SDK Tools with 4.4.2 and run through CMD line

[Completed] My xperia c4 dual (e5363) hard bricked

Hey guys i regularly follow ur posts and those are really helpful but its the first time i am writing as i am ****ed up with my xperia c4 device. Recently i upgraded my xperia c4 to android 6.0.1 marshmallow using your flash tool flash method as i had unlocked my bootloader. after that i found that my device isn't booting into recovery mode. whenever i tried to boot into recovery it stucks at sony xperia logo and after some while it restarts automatically to the system. So i thought the recovery might be deleted when i was flashing the firmware. i was using twrp recovery made by u guys
PHP:
http://forum.xda-developers.com/xperia-c5-ultra/development/bootloader-unlocked-custom-recovery-t3285521
so I flashed that again using fastboot mode and it failed to flash and after that my phone gone totally black. Now none of the switches are working when pressing the power key its not even vibrating. when plugging it to pc via usb top notification led shows red and its not blinking. and the phone is automatically disconnecting after a while. i tried to flash the rom again through flash tool but it is showing "the device is connected usb debugging is off".
I am going crazy. please guys help me to fix this.:crying:

[Completed] is this a soft brick or a hard brick? can i fix my phone?

I've been trying to root my phone for the last few days, everything just seems to be going badly.
I was finally able to unlock the bootloader, and i wasn't able to flash TWRP
after trying to get it to work and faffing around in recovery. I some how have got my phone in an endless loop. But not just an endless loop, but after the phone logo comes up, my phone's screen goes all glitchy and crazy with loads of colour. I can go into fastboot mode all ok, but now i can't access recovery mode anymore it's the same as normal mode.
I have no idea what's going on
i can't flash anything, when i do i get the message USB Transferring ... USB Transmission OK
Hi !
This looks like a soft brick but can you tell us more about your device ( model , software ) ?
Thank you

Hi !
Some devices just can`t be unlocked without a prover support from the manufacturer
You can search for more on Google and wait for development , your case is far from unique
I see that you have alredy posted same issue here

I used Lineage os for 2 months . then I want to get my stock ROM back so I restored it from twrp and after restoration completed I found my phone IMEI no was empty and network not working so. I again install Lineage Os then Lineage boot animation started as normally but after 5 min black screen appears and my phone screen starts blinking Lenovo logo comes and then automatic power off this process happeneds again and again. So I tried to open twrp recovery but unfortunately its also not opening . now I have left fastboot mode and download mode .
I see many threads then I QFIL application that helps in flashing stock ROM I tried many time but my laptop always says sahara fail or sahara error. I am tired of that fail . I tried latest and old version of QFIL but not working in my laptop .... Can anyone help plz .....
Can I can install stock ROM with fastboot mode if yes plz guide me and give me fastboot commands ...
Thanks for making your precious time for reading my thread .....
Try to Clear Windows Registry , with CCleaner , Open Qfil with Administrator put firmware , remove battery , press vol + and power key , plug in battery and plug usb in , wait when the COM port is detected on Qfil , and start flash .
What is unable to flash download using sahara protocol ?? Why this happeneds ??
