Hi Friends,
I'm trying to unloack my Z1C using the latest verson of flashtool and after connecting it in flashmode it will not display the window showing model numbers and display a window asking to switch off and connect again in flashmode.
I've tried it on 3 PC's, still not unlocked the Bootloader. What is the difference between unlocking bootloader from Sony official method and Flashtool method. Please guide me.
Regards
Shashi

Iirc the first unlock has to be done the official way, then you can (re)lock using flashtool. And the correct drivers have to be installed of course.

[Q] Problem on Unlocking Bootloader using AndroidSDK For Sony Xperia M / C1904

I have the latest officially firmware update for my Xperia M running on Android 4.3.
While trying to unlock my bootloader it got bricked and the Xperia boot animation kept on loading.
I followed all the steps and gave every commands to unlock my bootloader given in the official Sony developer website for my Sony Xperia device.
Since its not booting into my homescreen I gave my device to the Sony Authourised Service Centre where they are asking to replace a new motherboard.
DOES UNLOCKING THE BOOTLOADER CAUSE ANY DAMAGE TO THE DEVICE MOTHERBOARD?????

Sir,
Please wait until mods will move this thread to the device specific forum.
Stand by
Until then read this thread: [TUTORIAL] Xperia M Bootloader Unlocking
Good luck

flash the stock firmware

[Q] Can't unlock Xperia M bootloader

I'm unable to unlock my Xpeira M Single Sim Bootloader. I have checked in the service menu that it is unlockable and I also have a unlocking key but when I connect my phone in flashmode it says that "Your phone bootloader cannot be officially unlocked". What should I do?

You might want to take a look at this video "How to install Android Lollipop in Xperia M (CyanogenMod 12)" from Xperia M Tweaks on youtube. Just follow the steps till bootloader unlock and leave out the rest. Hope this helps.
