Default Stuck in a Bootloop/Boot stall Z1(Sony Logo) Pz Help!

Hello!

I upgraded my z1 to 4.3 but while attempting to make a call my phone froze and after restarting i was stuck in a boot loop.
I've very carefully went through many threads and finally decided to post because after trying all the methods i'm still stuck at boot stall. (Sony logo)

I've used the flashtool ( Version 0.9.13.0 ) to flash the latest FTF (C6903 14.2.A.0.290 Central Europe 1276-4314_R1B) But to no avail. I've also tried resetting it through SUS (complete system format/factory reset) and its the same.

Also tried downgrading to .257 and i'm still stuck with the same bootloop.

Here are the logs from Flashtool, If this helps.

Rebooting is fine it gives three vibrations and shuts down.
I havent rooted the device. This is the first update i've tried.
Trying to download C6903_14.1.G.2.257_GLOBAL-LTE (1277-1398).ftf to see if that would help but unfortunately, can't download, gets stuck , Temporary error, retrying.

Any help will be appreciated, i'm at my wits end trying to revive this phone but i just can't seem to understand where i'm going wrong.
Thanks in advance!

Did you do a wipe data, cache, appslog when you updated? and did you uncheck "no final validation" and everything else?

Yes I checked the options for wipe appslog/cache/data and left the exclude option unchecked and checked "no final validation"
It flashes the FTF but still stuck in the sony logo loop.

I assume that you can turn it on, but you get stuck in a bootloop.
Power it off (VOL up + power button) then keep holding VOL down + power button, when it starts booting, release the power button and keep holding the VOL down. This should boot you into safe mode (people call it debugging mode as it only loads preinstalled apps and the things it needs to boot with 0 customizations made)
Don't forget to hit the THANKS button! If I helped.

I mean did you unchecked this "no final validation" Right? You phone still power up so switch it off, keep pressing volume down and connect to pc, let windows install drivers, do not install the manually into flashtool, keep pressing volume down and flash again the FTF, if the problem still there you can also try different FTF to be sure, maybe the FTF is the problem.

Yes i did uncheck it.
I think the FTF is the problem, but i've tried many FTS's now, the only one that at least booted the phone was C6903 14.1.G.1.534 Global 1277-2880_R4A this also started after a few bootloops but in the end it started. I saw the settings and it Baseband version was unknown. 3 minutes later the phone rebooted and went into a bootloop again.

I updated via SUS hoping it would fix the baseband problem but still the same.

No luck
