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
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.
