Should be fine using PC Companion as long as you don't unlock the bootloader. Restoring to a stock firmware isn't to hard anyway using Flashtool

Yes you can just by using Flashtool and downloading a ftf, easy and handy to have when you are on locked bootloader.
PC Companion wipes your data unlike flashtool (just untick wipe data

TWRP?

Does anyone currently plan to port TWRP to the Xperia T?
I'm no developer but I'd love to see a port of TWRP on my device.
I might try to do it myself following TeamWin's guides but I'd be a bit worried about bricking devices, especially my own!
if u brick theres always sony's restore program!
Sounds good, which one?
Just flash a stock .ftf firmware file with flashtool
Or use Sony update service, or pc companion

Once on a custom rom seus says "modified firmware - update not possible" (or something like that )

Thats becuae we have to unlock the bootloader to install custom roms at the moment.
But, you can always flash .ftfs in flashtool.

I reinstalled pc companion and hard reset, but never tried Emma flash tools, I guess it needs unlocked bootlader and don't think I have it. Will it harm the phone if I try, anyway? Thanks

You must flash the stock rom using flashtool -> relock the bootloader -> restore TA partition

[Q] How to go back to Stock official ROM sony xperia z1

I'm on ihackers 2.1 ROM android 4.3
rooted
unlocked bootloader
I wanted to go back to stock to C6902_14.2.A.0.290
I found the method but I'm not sure if this is the right way http://lionking853.blogspot.co.uk/2013/11/how-to-go-back-to-stock-firmware-on.html
and if it is the right way, after going back to stock ROM, will my phone unroot and relock again?
Can I just go ahead and do this or must I relock bootloader first?
please help me since I never done this before, only rooted and unlock that I did.
Thank you so much folks

if you don't want to relock your bootloader then just go back to .290 with flashtool

Thank you, I'll do that

I'm finally back to stock ROM and it's much faster than custom ROM
I think it is much more stable too.
I'm no longer rooted anymore but bootloader is still unlocked.
I'm happy now

If you have an unlocked bootloader, you will not be able to update using PC Companion. I didnt know all this **** were involved in Sony phones.
I had unlocked my bootloader a couple of days back, didnt know I had to backup my DRM keys and ended up losing my warranty. Now I cant even update my phone using the official updating method.
BTW... the recovery is bundled with the kernel, thats why people refer to it as flashing a kernel instead of recovery. I didnt know this until 2 days back.
Thanks

If you do have a TA backup then you don't have to do anything else then restoring it on a stock rooted firmware..If you don't then use flashtool to relock it..
Revert back for more help..

If I am on a Locked Bootloader and on a rooted custom ROM, will Sony PC Companion detect my phone when the next update comes??
This is stupid. If you are in 4.3 (.290) with un-locked boot loader you cant update via PC companion or SUS.
I ended up going to 534 (4.2) via flashtool. Root it, restore TA backup and then use SUS to update. And flashing the latest 4.3 via Flashtool din work.
No PC Companion or SUS won't detect your phone.. You've to manually flash a valid ftf from Flashtool.. Then you can connect & update your phone through PC Companion or SUS..

The easiest way is to use Flashtool. Just download an FTF of newest firmware and flash it using the software:
Once you are on a stock rom with stock kernel you can restore TA backup (if you have one), this will also relock your bootloader. It is best to restore TA on the same firmware that you did the backup.
