wt19i LwW. Using wotanserver to flash, I lost the warranty ?

[#1]

Hello.
I have a question.

I have a branded phone (live with walkman).
I want to debrand (flash with original SE rom) by this site/software:
http://www.wotanserver.com/en/sony-ericsson/se/live-with-walkman-wt19/unlock-tool/debranding-flash

If I make this, I lost the warranty???

If you want to install custom ROMs we can only recommend this website:

http://unlockbootloader.sonymobile.com/

Please note that you may void the warranty of your phone if you unlock the boot loader. Sony Mobile can then no longer guarantee the full functionality of your phone, and will not be responsible for any unsigned custom software being flashed to the phone after the boot loader is unlocked.

You should only unlock the boot loader of your phone if you are an advanced user with good knowledge of the technology and risks involved. We strongly recommend that standard users NOT unlock the boot loader, as it is not needed. We are proud to deliver great phone experiences through our rigorously tested and official software releases.

flashing Sony's official firmware still might void your warranty

you can use wotanserver or flashtool

Live w/ Walkman WT19i 2.3.4 Build number 4.0.2.A.0.62

I now not understand.

Question:

If I succesfully flash the phone with wotanserver or flashtool (with SE official firmware) and NOT unlock the bootloader (save originally settings),
Will I not lose the warranty ?

I call to support in my country. Answer is: You lost the warranty.

[Uliwooly]

yeah, it varies country to country, I don't agree with that statement that flashing original SE firmware voids warranty, it shouldn't be like that, but you can always flash the original firmware

ok, thanks.
How to safety backup current firmware ?

[Uliwooly]

Open SEUS or PCC and then click "repair" firmware. It will reflash your device and download some files called "FILEXXXXXXXX" where the XXXXXXX is a number.

This files are in the folder /db/blobs/yyyyyyyy/ where yyyyyy is a number too.

Copy out the FILE_XXXXXX files to a backup folder. Now go into flashtool -> Advanced -> Decrypt .... Put into the files from your backup and Flashtool will create you a flashable version of your Rom
