[Xperia Z1 Compact Q&A, Help & Troubleshooting] annersd:
I have a similar problem: I tried to root my friend's device but I messed up. Maybe you'll be able to help me?

tl,dr: Phone bricked and restarts. FTF or FT wrong version? Code attached

My device (also Z1 compact) runs on lollipop and I ensured USB Debugging was on (foreshadowing: Now it says it's off). With Flashtool vers. 0.9.23.1 I tried to flash the FTF D5503_14.4.A.0.108_EURO. What I did was excluding kernel and partition so the data wouldn't be overwritten (maybe that was the mistake?). Anyway, it was stuck in starting mode - turning itselft off after the Sony sign and restarting again.

I then panicked and tried to flash the FTF with every box checked: Started a little bit longer only to restart again while caught in the starting animation. So I tried to flash the stock FTF which I think to be the D5503_14.4.A.0.108_EVO (unsure though) but it didn't change anything. Meanwhile Flashtool tells me, that USB Debugging is turned off (see last lines of copied code).

Can anyone help me pointing out what I can do? Maybe with

the correct FTF

the correct version of FT

the correct boxes I need to check

pointing to the stick I have to hit myself with on the head

something else?

I sure hope that someone can help me, although this thread is fairly old and so is the mobile.

Thanks, cheers anners

edit: I helped myself out: Someone (I think it was here) mentioned it earlier. Got to sonymobile.com, download the Xperia Companion and choose to repair your phone. Be aware: All your data is lost.

Is there any way to restore the data I just lost? I have hear about some programs, but which ones are best? And how can I root my phone to be able to use the restore programs properly? I am nervous about the next try.. :laugh:
