Xperia S Bootloader

Sun, 27 May 2012 19:40:44 GMT

Hi guys,

Just a quick question. I'd like to unlock my Xperia S bootloader. I understand fully regarding warranty issues.

The question is, is there any way they can detect after I re-lock the bootloader?

TIA.

if you unlock your bootloader you will lose the DRM files forever, no you can not restore them, so sony will find out

I haven't seen a coment from a SONY moderator saying that "IT WILL" void your warranty, even if you go to the unlocking bootloader website it doesn't say that "IT WILL" void your warranty, it says "IT COULD" void your warranty, so don't be afraid, you can unroot anytime.

http://unlockbootloader.sonymobile.com/instructions

Warning! If you perform this step, you will unlock the boot loader. This may void your warranty and/or any warranty from your operator. If you still want to unlock the boot loader of your phone, enter fastboot.exe -i 0x0fce oem unlock 0xKEY, where KEY is the unlock boot loader key you got in the beginning of this instruction. The boot loader should now be successfully unlocked.

I know I did said in the past that unlocking your bootloader will void your bootloader, well I take it back, it doesn't void your warranty it COULD void it.

In theory they could detect it, however I highly doubt anyone in a repair center really cares. Repair centers use Emma (special software) to flash and check devices, and when you relock the bootloader it is impossible to see in Emma if it was unlocked before or not.

You can check it yourself easily. If PC Companion and/or Update Service still want to redownload and reinstall your firmware, you will be fine.

(Emma does have a section where it shows the DRM status, but for some reason it doesn't mark missing DRM files, I've tried it with a friend's Arc S.)

However, unlocking the bootloader is still a risk, and something you should only do if you are experienced and can rescue your device yourself should something go wrong with flashing custom software.

@ullwooly,

Yeap knew regarding the DRM that it will be lost forever.

@Ambroos,

Yes! That is the answer I wanted to hear. LOL. Me too. I dont think they will really be 100% strict. I mean if its just the LCD tint problem, I dont think they will check until that extend. Don't worry. Flashed alot and revived bricked phones till date. Lol.

Thanks guys for the answers! Appreciate it! ;D

I don't have any 'relocked' devices available right now, but I'll take a screenshot as soon as I have the chance!
