[Xperia Z3 Compact Q&A, Help & Troubleshooting] multiwirth:
Hi everyone,

hope you´re all doing well.

Usually i don´t post alot questions here but i don´t know any other place.

I´ve got a xperia z3 compact from a german seller claiming it as new and unused, but no box and only charger included.

I wonder where they´re coming from...

Well it turned out like nfc totally won´t do anything.

Can´t be enabled at all!

Don´t know about the rest of it, seems like gps also doesn´t work but have to test it in more detail.

It ´s 100% stock, non unlocked, non rooted or tampered in any form.

What i tried so far:

- Running official sony companion software from two different computers to try repairing the firmware.

It failes every time.

-Next attempt was the not so familar flashtool for sony devices.

Downloaded the latest firmware for germany and italy aswell as russian from this thread

None of them will flash, all exit with the same error:
