hello to everyone if you have had the problem of the "bootloader unkown" here's a simple guide to solve it I tested on my Xperia z3 d6603 but I think worth for each Sony Xperia
1) most likely you will have performed a factory reset you tried relock your bootloader but all this is useless
2) first you need to obviously have drivers and flashtool installed correctly
3) most likely the problem is the version of the firmware so for example I had kitkat so I installed a fw with lollipop
4) Once finished flash fw repeats the process for unlocking the bootloader and everything should return to normal with unlocked bootloader properly and modding possibilities I hope to be helpful

So i had the bootloader of my phone unlocked, but almost every Sony Xperia E user is facing a bootloop problem after unlocking the bootloader. So i reflashed the whole stock rom (.ftf) and the bootloop error is now gone. But i want to know if the bootloader is still unlocked, because i want to flash a new kernel. But in order to flash a kernel, you need to have the bootloader unlocked. Any suggestions???
Yes, it is still unlocked
I have Sony Xperia L - Jellybean 4.2.2 - 15.3.A.1.17 - Rooted Stock ROM - Locked Bootloader
For some reasons I have to make a hard factory reset with Sony Update Service program, but instead of letting the program re-download the firmware then installing it on the phone, I already made the FTF file that I downloaded in the past by using the Flashtool.
Now The Question Is:
Have I worry about losing the DRM Keys when I flash this FTF with the Flashtool ?, or this kind of flashing will not affect it ?, or I have to check Exclude TA in the Flashtool ?
Hey , anyone please help me
Hi,
i want to update my xperia z3 D6603 to the newest Lollipop 5.0.2 Update.
If I want to do this via PC Companion, but I got an error 2003 that it can't update my phone. I think this is happening because I unlocked the bootloader.
The currently installed version is 4.4.4 (23.0.1.A.5.77). This was installed from a service company, so I don't have any clue how to flash my device to the new lollipop 5.0.2.
Can you tell me what I need for the installation? Is there a complete tutorial for it?
I already downloaded flashtool and found the custom lollipop roms here. Do i just have to go into the flashmode, start the flashtool and flash the new image?
Looking forward to get some help from you
greetings

Yes, you're right. Just follow the on screen instructions of flashtool and you should be good to go
Hi,
My dad recentely upgrade his XZ, but it didn't work and the phone is in bootloop. So I try ti use Xperia Companion to repair it but pass 10% there is a error message and it can't go further...
So my question is can i make a factory reset using a Stock firmware with Flashtool without loosing the TA partition ? (the phone is full stock so the bootloader is lock and my dad want to keep is waranty) (I try some researches but i didnt found any answers about flashing a stock rom with flashtool, all i found is how to flash a custom rom)
Thx,
Valentin
Flashing a FTF will do nothing to the TA partition. You are safe to proceed
Hi,
I tried to root my Xperia Z3 D6603 with flashtool. I downloaded the Global firmware version 23.0.A.2.93 since my bootloader is locked to root my device. Once flashed, my device boot normally, but it says contacts has stopped and then reboot over and over again. My phone is the Canadian version and i'm wondering if there is something to troubleshoot my problem.
Thank you very much
Michel
download the different stock rom and flash it again
