[Q] SUS no longer works ("modified software"), phone is rooted with locked bootloader

[Q] SUS no longer works ("modified software"), phone is rooted with locked bootloader
Hi,
I was trying to help someone on the Dutch forum of Androidworld.nl who is unable to update or restore his C6603 using Sony Update Service due to "modified software". He says that he only rooted his phone (using Bin4ry's tool) and that he did not unlock his bootloader, nor any other mods.
In his service menu, under ‘Service Info’ > ‘Configuration’, he currently has "Bootloader unlock allowed: No." (probably due to the root). Under ‘Service tests’ > ‘Security’ it just says 'none'. He still has his four certificates under ‘Service tests’ > ‘Verify certificates’ and Mobile BRAVIA Engine 2 is still working for photos in the album app.
Does anyone have any idea what can be the cause of this?
He has a branded firmware from his carrier (Vodafone NL), which is not available as FTF, so he would lose this by flashing the Generic NL version with Flashtool.

He need someone to upload the same firmware for him or he can flash any available firmware.

That would be a solution, but do you have any idea why Sony Update Service would refuse to update or restore his phone and give the "modified software" error? I thought this only happens if you unlocked your bootloader?

Not sure what is the cause,maybe he has some system files modified.
Maybe he can try the bootloader status fix by @fareeed and try sus again.
Will try to find the link.

Thanks! Probably a noob question, but how do you flash a ZIP if you don't have an unlocked bootloader + recovery?

Root and install it, links in the stickys.

It's a single file just replace it in the corresponding folder with root explorer.

Rooted and updating to 4.3

Hey guys I have a rooted Xperia Sp(C5302). We know that our device is gonna get the 4.3 official update next month. My question is can we update to the official 4.3 even after having root or will it cause a problem.

As said above, root is no problem with PC Companion.
However, if you unlock the bootloader, no update whatsoever (PC Comp, OTA). After bootloader unlock only Flashtool /Emma will let you flash new ROM/updates.

Hi , so if i Relock the boot loader i will be able to use ota rite?
which is the safest method to Reload the Boot loader
I am using BL Unlocked Rooted Stock Rom ,

I think Sony stated on their unlock website that once you unlock the boot loader there's no way to relock. Check out unlockbootloader.sonymobile.com

Thank you very much. I've waiting for this

For one last question,
To flash the stock rom without unlocking bootloader I must flash stock rom with Sony Emma , PC Companion or another flash tools?

You will always lose signal when flashing back down to 534, you will get it back when you upgrade

OP, you should just flash a 757 FTF then a custom kernel.
Bang, you have root!

Isn't that possible if you go into flashmode?

No, you cannot use Pccompanion to update software with an unlocked bootloader. It downloads the files but then stops with a warning saying you have modified the software (i.e rooted the bootloader) and then aborts

Thanks. I wasn't sure about this as my old xperia play barely got any software updates. Duh. It was released with Android 2.3.3 and left at 2.3.7. Since the Z1 is really powerful and custom kernels don't really give that much of improvements or actually useful features (d2tw drains the battery like crazy) then I decided to stay on stock kernel with LB to keep bionz and other stock features.
