About rooting.

[nfsmw_gr]

Hi all.

My questions should have already been answered but I want definitive and up to date answers, since this will be my first sony device in years and I wouldn't want to waste my money.
So, here we go!

1) Can I root my device without loosing warranty?

2) I saw there is a ta backup utility, if I use this my warranty will be okay if i restore before sending in the device?

3) I found a 4 month used one, at a good price and I want to check if it has been rooted and in conclusion if the warranty is valid or not. How can I do this?

Again I am deeply sorry for asking!


EDIT:
Found this, is this valid?

Can I root and just unroot be ok?
What about flashing roms on locked bootloader?
If I restore my stock rom would I still be covered as long as we talk about warranty?

Sony has changed their warrenty recently

Rooting doesnt void your warreny but breaks ota updates untill you undo and unroot the device

You can flash a FTF using flashtool to restore totaly stock firmware if you want

Xperia warrenties are valid from when you purchase
Given proof of purchase and date of purchase your warrenty will start there
2 years insternational warrenty for all devices


If a device has been rooted it will most likely have superuser or supersu app

And if it doesnt you can just check using root checket, and even then you can just flash a FTF file to fully factory reset the device

What about the TA Partition?
Is there any way to check if this is ok or not?
Unlocking the bootloader voids warranty, right?

P.S. Could you send me a link about Sony changing it's warranty, can't find it.

Ta partition, its currently imposible to check its contents

Unlocking your bootloader will wipe your TA and void your warrenty

The warrenty info should be somewhere on the sonymobile website

Thanks again mate.

Oh.. Relocking your bootloader doesnt bring back its contents, aka DRM keys

Also Nothing is lost exept warrenty when unlocking your bootloader however this varies depending on your country, branding or version of the unit

Most versions just lose X-reality

Got it.
If I had backed up the TA Partition (which contains the DRM keys) and flashed stock firmware, restored the keys and relocked my bl, would I be ok?
So the only way to lose warranty is unlock the bootloader?
If i flash a rom, on locked bl, my warranty would be ok after I unrooted and restored factory firmware?

Restoring your TA relocks your bootloader

1. Backup TA
2. Unlock bootloader
2. Rom/kernel flashing time
3. Flash totaly stock kernel (from ftf)
4. Restore TA

Restoring your TA brings back your warrenty :/

Flashing a rom on Locked BL i dont know that affects the warrenty because ive never fully read it/cared for it

Restoring stock fw should reinstate the warrenty because the device isnt concidered modified

I think to get the best info, go and find the sony mobile warrenty info
