[Read issue in my post] installed twrp as boot/ problem with flashtool etc..

[Mantize]

Okay so here is my issue. I wanted to root/flash my sony xperia z3 d6616. Okay followed the instructions and unlocked bootloader. Then I wanted to backup existing ROM etc. so I googled it and found out that for this I will need to have some recovery like TWRP.

I went installed TWRP with “fastboot flash boot twrp.img” – I should have done “fastboot flash recovery twrp.img” which means I am stuck here now...

Then I searched for official firmware. Found that (https://forum.xda-developers.com/z3/general/ftf-stock-firmwares-xperia-z3-models-t2886061) with ftf extension. Installed fastboot/drivers let it run few times already and nothing.
I get something like this
INFO – Flashing finished.
INFO – Please unplug and start your phone
INFO – For flashtool, Unknown sources and Debugging must be checked in phone settings
INFO – Device disconnected
Like it went through if I see? Or this Debugging option is the problem?

Not sure what can I do now. Is it possible to get android working from this point or should I just throw my phone away now? Please if you know how to fix this or if you have any idea tell me. I will appreciate it a lot.

Or am I doing it wrong? As I found that it should be better to exclude sin – kernel while trying this stock ftf? Should I include it next time?

Or if anybody could advise me where to get like this boot image. Or I should try to install some custom ROM and it might work and I could get my android system again.

Your phone doesn't power on after flashing stock fw via flashtool?
It should start normally if you flashed the correct fw.

After doing this with flashtool my phone powers on. But it boots to TWRP, like it did nothing. If this makes any sense to you. Like flashing has done nothing.

Not sure if this line INFO – For flashtool, Unknown sources and Debugging must be checked in phone settings
might be the problem? Since it states that my Debugging must be checked? But since I overridden my boot image with TWRP I am unable to go to settings to change this.

Thank you for quick reply.
