[Sony Cross-Device General] xaser66:
Xperia Z5 Premiun E6883 bricked after reset

Hello, and first, thanks to OP and all people for this thread.

Well, long story, short as possible, I root my Xperia Z5 premiun dual E6883 in January, and installed TWRP and romAUR for my device, and it was working almost fine since then except for few occasional FC that seems due to rom current development but for the most, my phone was working pretty fine until past friday.

That day, my phone was a low battery at night, and when I try to check a last messague on it and before put to cherage, I found it with a pulsing white Led (that was a color that I set to led for pending emails), but when I try to open screen, dont response from phone and only black screen. Since is something that I found in the past, I simply choose to reset with the hidden butoon under sim cover, but made the mistake that I press the hidden button while still maintained pressed the power button. However the phone made the 3 familiar vibrations that confirmas that was reset, but, after that I try to restart it and never response (No light charge, No vibrations and no screen of any type...)

After that , I was triying again to reset by hidden button, by Power+UPVolume key to turn off, and by maintaining press Power fot 120secs, as the first keys tricks that may help to restart phone without luck.

Then, I try it to my PC and at first, It was show on pc as QHUSB_BULK error usb device, and I made some other button attempts, looking for some response I got the phone change the messague, at the moment of connect it with usb cable to my pc, it was recognized as SEMC Flash Device... In both cases windows didnt allow or recognized for a proper driver installation....

After that I choose to leave it without any connection but with the 3 rubber band put over VolumeDOWN key, to try to maintain the Flash mode working, in hope for a full discharge, and 12 hours later I try again if I could get the RED charging led without luck. So I asume that the next best thing to do was to leave it connected to the wall charger for long time in hope to that when It discharges, the Red light may appears and allow for a recovery process. I leave the phone on charge during 24 hours and no Red light come, but I was checking and it was always little warn so I suppose that there be some electric current flowing to the circuits (No high heat, only warn but noticeable), after 24 hours, I think that may be enough, and that the better that I can do is leaving it for a full discharge again this time without any connection or trick and is in that status since 9 hours ago, and by checking it, it feels little warn (less that when it was charging, barely but noticeable respect other stuff in the same table).

As additional info, I bought my cell on Honk Kong, and in my country the service to it may be so high that could

So by now, I dissapointed and worried, so I would like to ask if may be possible some help...

1) In the experience of more skilled members on this thread, may believe that there is a chance that allow writing may discharge this phone, and if may be possible that Sony still uses the same charging protocol description in the first post or may be some reason for suspect a change in it respect to new xperias...

2) By the info on first posts seems that an Xperia Ion take until 51 hours for a full discharge (and the Ion have a battery of 1900mAh), so in the case of my Xperia Z5p (taht use a 3430mAh battery), may I suppose an aprox, that I may need to wait at least 4 days to discharge my phone without any connection (by calc, 51*(3430/1900)= 92hours~4days)...Is a good aprox to reasonably look for chance on connect to an usb to get a Red low battery charging signal... and if that not happen may it be a enough reason to thing that the next resource will be only to open the back cover to try disconnecting battery?...

3) If may somebody have some experience or advice that may share about, I would be very gratefull....

Best regards to all.
