Hello brickers and others.
Maybe i found THE solution for a hard bricked M4.
I was messing up my phone after flashing roms over each other and wiping several things several times.
So i hard bricked my phone i think because this is what the phone did :
In the first period the phone was starting but shows only the Sony logo for about 30 seconds and then the phone restarted automatically, and so on. That means i was in a boot loop.
I didn't came in to TWRP recovery mode. That did not working anymore
Pressing volume down button and connect to pc for Flashmode did not working too. I came into Flashmode and my pc whas finding the M4 but after 20 seconds or so the phone was rebooting by himself. Thus Flashmode was unuseable.
The volume up button for Fastboot mode was working very well.
Only, my point is i can't flash a firmware via Fastboot. I don't have enough experience that way, if it is possible at all. I don't know.
Okay, i was stuck at that point.
After flashing as a dumbass some kernels via Fastboot mode i came in the second period, a hard brick i think.
The only thing what my phone did now was going on for a few seconds (showing Sony logo) after a long press on the power button, and then it turns off.
TWRP recovery was also that time not working.
My phone was not showing the led when he turns on that few seconds.. I didn't came in Fastboot or Flash mode anymore (no led showing up). Nothing was working anymore except that the phone turns on for a few seconds after a long press on the power button.
THE SOLUTION
I hope for every M4 users i found the solution for this brick. I don't know if it is mentioned yet somewhere. I didn't find it. It feels like a secret combination but it worked for my M4 E2303.
"Press the volume up & volume down button at the same time and keep it pressed. Then press the power button and keep all these 3 buttons pressed, LONG pressed, TILL the following vibrating code has COMPLETED!!!"
Code: rrrrr rrr rrr rrr
Now you can release the buttons and Fastboot & Flash mode should work fine now. You can use Flashtool now to flash a STOCK firmware (tft file) via Flashmode.
After completing your phone is repaired.
Succes.
