Root, bootloader unlock and warranty - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Does the rooting avoid warranty in Ray?
I also want to unlock the bootloader to install CWM, how to relock it and to restore the phone without cwm just in case to send it to service center?

unofficial unlocking
oh my God..
this issue discussed in too much topics..
If you unlocked the bootloader with unofficial method without loosing DRM
than you can try to reflash with Wotan to the stock and then relock bootloader
and 95% that the service center they will not suspect anything
but dont forget what is the warrenty case.
if the reason of breakage is a factory production defect
than THEY will PAY for REPAIR
if YOU will break your phone then YOU will PAY for REPAIR

Thanks mate, I'm quite newbie in android
Can you please link to me the thread of this unlock/relock method ?

[Q] Confused with bootloader relocking

Hi guys, I'd like to unlock my Xperia Ray's bootloader, but I don't want my warranty to be void. I know this is impossilbe, but it seems it is possible to get it back by relocking the bootloader, like on this thread : http://forum.xda-developers.com/showthread.php?t=1862045
So, I was about to unclock my bootloader because I was sure I could send back my phone to warranty in case it would have a problem. :laugh:
But then I saw this other thread : http://forum.xda-developers.com/showthread.php?t=1752009
So I'm getting confused, will relocking my bootloader get my warranty back ?
Help me please
Cant say really ...
it's like a lottery ...
It's at the total discretion on sony's part to grant you warranty ...
Unlocking BL will erase the DRM which cant be restored even if BL is locked ...
Just assume ,your warranty is void when you unlock BL ..
Okay.
I'll wait my warranty to be finished to unlock my bootloader then. :good:
Thanks for your help.
If anyone has more informations though, post it here please.

MOTO E Unlock and relock bootloader without voiding warranty

Hi
Guys i recently bought MOTO E and I want to know method about relocking boootloader ? and How can we claim warranty again.
As in SONY devices we can take backup of DRM keys before unlocking bootloader so we have warranty.
LG devices flashtool can restore bootloader to it's original condition so no worry.
What about Motorola? is there any method should i know ? How can we have both warranty and unlocked device.
Good luck

You can unlock your bootloader from motorola website and what i know is that once you unlocked your bootloader your warrantly is lost whether you later lock your bootloader before going to service centre. So once unlocked mean lost warranty

What I have to do before sony service?

Hi.
I have some problems with my mini jack. When I plug headphones it sometimes work sometimes not. I think it is messed up. Phone still has waranity, so maybe they fix it.
My question is:
What I have to do before I leave my phone in service center?
Do I have to relock my bootloader or just flash stock ICS?
will they check software if phone has hardware problem?
Thanks in advance!
Cheers

You should relock the bootloader and restore drm keys of possible.
Relocking bootloader is a must as it is the first thing they check.
Relocking the bl should be enough but sometimes sony checks more deeper for the drm keys. So if you have backed up then restore your TA.
And you should flash the latest stock firmware.
They must probably will check bootloader status.
When my touchscreen wasnt working correctly, i just flashed ICS and relocked bootloader without restoring drm keys (i didnt backed it up when i unlocked). Apearrently they didn't checked the software and just sent me a new phone.
If you just relock the bootloader they can check the drm keys and will know you unlocked it before. But I don't see a reason why they will remove your warranty because of that, giving the fact that nothing software-wise can screw your headphone jack.
@Twski
Depends on the employee who checks your phone. If he checks for drm keys then he knows that you unblocked your bootloader and your warranty is void.
But mostly they just check the bootloader status like they did last time.
And unlocking the bootloader will void the warranty no matter what the problem is. While unlocking the bootloader they clearly told you that.

Thank you guys for reply!
I will relock bootloader, flash latest stock and go to sony service.
Edit: And if I want to unlock it again after it return to me, the procedure is the same like 1st time unlocking?
Yes.

[Q] Without voiding the warranty, what can safely be done?

I know rooting can be undone, but if I need to send the phone in for repairs is it safe to unlock the boot loader, flash ROMs and install alternative recoveries like CWM? Perhaps there's no way to relock and unlock bootloader yet but maybe there will be in the future. Can these be undone or do they void the warrent in the first place?
Why don't you ask Sony? Any answer you get here is hearsay and assumptions. Additionally if people have been able to so things in the past should be relied upon as principle.

Well, I have my phone rooted (without unlocking bootloader. You only need to unlock your bootloader to install a custom kernel. If you do this you need to back up your TA) and I still have my TA partition (needed for DRM keys) still intact. IF I needed to send my phone for repair under warranty (assuming it is non firmware related) all I would need to do is repair phone via PC Companion and send it in. I'm sure other people have different view points so it would be advisable to get more opinions to get a general consensus on the matter.
I contacted Sony today and asked if rooting android or unlocking the bootloader could void the warranty and they said
"all the process related to tampered or modify the software of the phone can void the warranty, also physical damage or water damage"
so it beets me what the warranty does cover.
As far as I'm aware "what the don't know wont hurt them..." so as long as you have your TA partition intact and bootloader locked when you send it in and a stock firmware installed then, in theory, they should be none the wiser. The same goes for shamsung phones pre knox. If it is in a stock state then all is good. Other than that; read, back up, modify to your hearts content m8:victory:

[QUESTION] warranty after bootloader unlock?

I've brought this phone recently and I just want to know if I unlock the bootloader officially then will I lose warranty?
I read it somewhere that even if I unlock bootloader and use the stock miui rom (or after having a problem return to miui) then it would be covered under warranty.
please clear my doubts about the warranty stuff
No, unlocking the bootloader will not cause you to loose the warranty. If it did, Xiaomi wouldn't have you to create an account and apply and wait for permissions to unlock the bootloader in the first place. But if you install a custom rom/firmware and the phone sustains some kind of damage, you might want to re-flash original MIUI before sending it in for repair or they might reject it.

thanks for replying
when I was unlocking my moto e (1st gen) I had to get some code from the company website and they would void the warranty, then
same goes for zenfone 5 where I had to use an official apk to unlock and they void the warranty too
but thank you ,its good to know
I want to ask one more question
during the procedure of sending unlock request I read that unlocking bootloader would serve as service end. what does that mean?
Unlocking bootloader will not void warranty.
Only installing custom ROMs will void warranty.
Well if you email them, they do say it WILL void warranty.
well I have to get root and xposed either now or later.. thanks everybody
I've just read a screenshot from an e-mail by xiaomi on MIUI forum which stated unlocking bootloader voids warranty.
I was denied warranty for flashing official ROM. Xiaomi is an awful company to deal with.
