I tried putting the following rom

Xperia ZQ (C6503)_4.2.2 - 10.3.A.0.423 - 1270-5681 R4B_Brazil Generic.ftf
Xperia ZQ (C6503)_4.2.2 - 10.3.1.A.2.67 - 1270-5681 R6B_Brazil Generic.ftf
Xperia ZQ (C6503)_4.3 - 10.4.B.0.569 R2C - 1270-5681_Brazil Generic.ftf
C6503_10.3.1.A.2.67_Global-LTE.ftf

but when I start the phone, shows the sony logo and turn off the phone few minutes later.

i lock the bootloader ( because it's unlock ) and try again in pc companion. The program says that the rom was installed successfully but still with the same problem.

Did you select wipe data in flashtool while flashing? If no then do it again with wipe data selected

I am having a similar issue .. better described here

http://forum.xda-developers.com/show...&postcount=231
http://forum.xda-developers.com/show...&postcount=238

what works to revive my phone is letting the battery fully discharge until phone no longer boots ... then if i press power i get three red blinks to connect the phone to charger ... after a few minutes of charging the phone boots normally whatever rom ( stock or custom ) i have installed.

i am still checking into the issue ... it seems like a hw failure to me and will try to send it to warranty

you may try that in case all the things you have tried so far are failing
