[Xperia Z5 Compact Q&A, Help & Troubleshooting] solarlogos:
Ok so I installed XperiFirm and looked up available firmware for my CDA

( 1299-0272 ) It says

Available Firmware:

32.4.A.1.5.4 / R3E

32.2.A.5.11 / R8C

Available Updates:

32.3.A.0.376 / R4D

So which one shall i Download ? Seems like there is no .34 firmware ?

EDIT:

i downloaded the latest (R3E) made a bundle from it using flashtool 0.9.25.0 and latest xperfirm

i started flashing but keep getting this error

the phone starts up and says "the software update failed, make sure your phone is connected and try again"

what shall i do now ?

UPDATE: tried different versions of flashtool

0.9.25

0.9.22.3

0.9.18.6

0.9.18.5

and depending on the version either kernel.sin or system.sin leads to an error.

I also tried excluding the sin and flash it manually with fastboot but got further errors like "Invalid sparse file format at header magic"

i also tried the other available firmware with same errors

I´m gonna try some more flashtool-versions right now
