I've got an arc with an unlocked bootloader.
Initially, I kept putting off the decision to unlock it because I didn't want to lose the DRM keys but I got it done by the Test-point method via Omnius, when they had an Easter offer (FREE). Who can turn down such a great offer? LOL!
I did it because it allows me to flash kernels and ROMs as and when required. My main inclination was the flashing kernel bit. Plus rooting becomes a cakewalk.

Test Point method can't be updated via SEUS?
and it cant be relocked right?
I was thinking unlocking via test point or flashtool ?
which do it better?

I haven't really tried updating via SEUS after that because I didn't want to risk bricking it.
It can be relocked. Blagus supplied the file you need to flash with Flashtool already. But then again, there's no real point in locking it.
Well, the main reason I went with the test point method is because I didn't want to lose my DRM files, which in turn would affect TrackID. But the latest version of TrackID which is available on the market works even with an unlocked bootloader so there's nothing to worry. You can unlock it via the official Sony route.
Unless your bootloader unlock status says no, there's no need to go for the test-point method.
And FYI, Flashtool won't unlock your phone. It's great for flashing ROMs, kernels etc.

How to know whether the bootloader is unlocked?
i using testpoint but not really sure it unlocked

Try hotbooting/flashing a kernel.

THANKS
I just noted that the fix is * 0.8.6.0
- Added Xperia U, P, Sola, Ion to BL Unlock plugin.
* 0.8.5.0
- Fixed issue with turkish regional settings (and maybe others we don't know)
No more need to change regional settings to see FTF content.
* 0.8.4.0
- Repaired TA Backup / Restore / Editor (broken by 0.8.3)
* 0.8.3 :
- Fixed an issue in firmware selector. When partition categorie or TA categorie are excluded from
selection, it was not excluded from flashing.
- Elf Extractor now identifies the program type included into kernel (Image, ramdisk or rpm)
* 0.8.2.0 :
- Fixed an issue where fastboot mode is not handled correctly under linux.
* 0.8.1.0 :
- Fixed an issue where loader is not found when using BL Unlock or TA Backup/Restore/Editor
- Progressbar when flashing was not showing right progress.

Why don't you go the official Sony route to unlock your bootloader?
Thank members on their post which helped you. It's always a good idea. There's a dedicated button, if you didn't notice.

You do not need unlocked bootloader to use Flashtool.

I take the same error again with no final verification :/ what can I do

Try use another cable and another USB slot. If it's not gonna work try on another computer. Maybe drivers make this problem.

make sure you have correct .ftf ( is your downloaded firmware for Arc S? version ? )
and make sure you have at least 500 Mb in your hard drive that flashtool is in it.

yes it is lt18i but my phone is in mtp mode but it doesnt open how can I change this

if you have unlocked bootloader test to flash a custom kernel via fastboot... when this is possible try to enter recovery mode and do a factory reset... after that test again a flash via flashtool...

ooh
when your phone is ON and is pluged to PC (MTP or MSC) flashtool doesnt work !!!!!!!!
for using flashtool you most turn off your phone and then HOLD back key and then plug the usb cable
if you do it correct LED would be green...
and then you can flash your firmware...

What do you mean by "i am unroot my device" ? Your phone is an unrooted one or you want to unroot your phone ??
Install all drivers before using flashtool, else you will get similar errors.
check , usb debugging and unknown sources in settings in your phone.
Please if you can post the flashtool log.

Xperia M doesn't boot after unlocking bootloader

HELP NEEDED!
Hi guys,
So I tried to unlock bootloader on my Xperia M (C1904). And after unlocking, it doesn't boot anymore. Just shows "Sony", and "Xperia", then the wave animation forever.
First of all, I access to Sony Developer World for unlock bootloader key, then used flashtool's BLU feature. It successfully completed and said "Device will reboot into system now" However it showed the wave animation forever, (waited for around 20 or more minutes) but there was no change, so I flashed stock .ftf file via Flashmode. HOWEVER, everything was the same as before.
Then I used BLU feature again to try Re-locking the bootloader, but it said that "Processing of loader.sin finished with errors." and "Your phone bootloader cannot be officially unlocked". I am sure that my XM is bootloader unlocking supported, and flashtool successfully finished unlocking.
I searched around the Internet and found many people is having same problem with me.
I DID try using Sony PC Companion to repair the software, but as you can imagine. It simply showed ERROR.
I need your help as fast as possible.
Thank you, and sorry for my bad English btw.
PS I did read XDA threads about this problem, but nothing helped much.

Buddy download stock firmware that works with your device(c1904) and I have heard that newley flashtool have some bugs most of the peoples found it difficult to use due to error so download a old version of flashtool.
Here is the link for flashtool that I use
https://drive.google.com/file/d/0B3WS5xjTt_0tQTZzQmNiZFc0R2M/view?pref=2&pli=1
It works smooth and don't forget to install drivers for xperia M found in C:/Flashtool/drivers after unpacking flashtool

Thank you guys for helping me.
I tried re-locking and flashed the stock firmware, and now my XM is working normally again.
Now, the question is, "Is there a way to safely unlock bootloader without soft bricking?"

I had similar problems as described in the first thread.
My flashtool version was 0.9.19.8 and during the blu-process the level meter stucks.
With "new" version 09.18.1 - as mentioned in one of the early replys - everything worked well.

Buddy for first time soft bricking happens with all it happened with me too because for first time the DRM keys (a kind of key used to get sony official support and update OTA) get wiped forever since DRM keys are integral part of BOOT so it will led to softbrick only for first time after that you can easily unlock or relock your Device

Well, you should be able to check if your device is unlocked when you connect to flashtool, can't you?
