[Q]Rogers Xperia Arc FastBoot/Recovery/Lock Code Issues

Hey there, I have someone who locked themselves out of their Rogers Sony Xperia Arc and I'm trying to hard reset the device to remove the code and make the phone usable for them again.
Unfortunately as I've done my research it looks more and more like these branded phones can't be put in to fastboot mode so I can't unlock the bootloader. I've attempted to over ride the drivers, I've plugged the device in while off and held menu and I get a green/yellow LED indicator instead of the blue one I need, and have no access to the actual device itself when turned on due to the screen lock.
Can anyone help? I have the FastBoot folders and the USB drivers (x86 and x64) downloaded and ready to go as well as the key.

Flash a stock ftf or use the Update service, done.

I can't access the recovery menu to put it in to download mode. I must apologize if I sound like I don't know what I'm doing. I've never dealt with a Sony device before. Most of my experience is Samsung with a little HTC.
Could you explain what you mean a little bit better? Maybe link a tutorial? I'd be much obliged.

The Flashtool is simply what it says on the tin, it's a tool that flashes Firmware to your device in a similar manner as SEUS or PC Companion does except the Flashtool requires .ftf files which can be downloaded from your devices General or Development forum. This is generally the preferred method for Repairing your Phone if SEUS or PC Companion aren't an option or you just prefer not to use them. You can also use the Flashtool to flash a Generic .ftf to your device which will remove any Operator Branding from your device.
This video by BlueChipJ explains the process of using the Flashtool...
...or you can use (specific Phones only) the Official Sony Flash Tool. See maxio1998's thread for more info - [TOOL]Official Sony Flash Tool | Unlocked Devices

What did you do prior the issue started? Did you have any modifications? Custom ROM/kernel?
Safest solution - Reinstall phone firmware. Either with Flashtool or with Sony PC Companion. Flashtool guide can be found from my signature, the tutorial one.

Wrong. You can still use Flashtool even with a locked bootloader. If you're new to this, I suggest you use the PC Companion to repair your phone since it is easier.

Search around the forum, there's plenty of tutorials out there. Also do some research before you do anything to your phone. Don't try it if you cannot understand the instructions.

At sony's logo?
Then you dont have an unlock bootloader, and you can't install any CM based ROM.
Use the pc companion or whatever software recommended on those tutorials to flash an original firmware form sony and bring "back to life" your phone. I don't know if you need to root your phone again (it disappear)

Thanks guys flashing it worked...just needed to wipe cache thanks

can't start up Sony Xperia S

Hey guys,
I can't start up my Sony Xperia S. It just stucks at the SONY logo screen.
I've downloaded Xperia Companion and tried Software Repair, but it says cannot be repaired as the Bootloader is unlocked. Now I'm trying to lock the bootloader but I don't know how.
I'd like to reset my phone to its original form, i.e. bootloader locked and unrooted. Any ideas?
Btw, I'm using a Mac.
Any help/advice is much appreciated. Thanks!

I think I was trying to flash custom ROM.
But it didn't work and my phone just wouldn't start up, so I bought a new phone 6 months ago and put this aside.
Now I'd like to start up this phone and try to access my pictures etc.

OK download stock ftf (search Google for stock jelly bean for Xperia s). Then flash it by flashtool software. There is plenty of guide for how to flash official jellybean on Xperia s by flash tool.

Thanks for the advice!
I followed the instructions here: https://forum.xda-developers.com/showthread.php?t=2422053
Flash the official jellybean.
It has some progress but I still cannot start up my phone.
When I start it up, the Sony logo appears, followed by the Xperia logo and the colourful light stream. Then it repeats itself, SONY, Xperia, light stream........ etc.
It's better than just the SONY logo I had before.
What should I do next?

Give it some more time on that state.. It should boot OK.. If not then flash again.

I flash it again, and still it can't start up.
I gave it 30 minutes, and it's still in the loop, Sony - Xperia - lights.
what should I do?
I've also tried to repair using the Xperia Companion but it says, bootloader is unlocked, so NO.
how to relock the bootloader then?

It's really strange why this happend to you... Are you flashing the correct ftf?try a custom rom ad see what's happening

i believe that the latest flash tool doesnt work with xperia s anymore so look for an older version

Use emma..
