Bootloader and warranty - Lenovo P2 Questions & Answers

Does unlock bootloader cause end of warranty? If yes could I lock it again if I would use warranty for repair?

Yes, you lose the warranty. No, relocking is not possible. The unlocking is registered at the Lenovo Servers.

[q]unlock boatloader

planning to unlock boatloader of my Play, but according to the Sony method, warranty will void, and even faulty hardware itself will not be covered by warranty.
found another way to unlock boatloader using the point-test thing, but seems to be kind of risky too.
may i know most of you guys here used which method to unlock your boatloader?
in a great dilemma now!
why not unlock and relock.
You can unlock and re-lock your bootloader.
Unlock using: http://adfoc.us/423185576865
And relock using this : http://adfoc.us/423185576880
I'm not 100% sure that sony can test that it was unlocked after re-locking but it does indeed work with SEUS after you bootloader is locked back.

Bootloader unlocking voids warranty but you can relock the bootloader. By doing that you get back your warranty..
Press thnx if I helped.

"Bootloader unlocking voids warranty but you can relock the bootloader. By doing that you get back your warranty." -Wrong information.
You do not get the warranty back even after you relock the bootloader.
Because bootloader unlocking will result DRM keys loss and also the IMEI number is logged by SONY, so even if you relock the bootloader that KEY can not be restored. So SONY can track it easily.\
So warranty remains void.

This is not completely accurate.
Actually if you read from Sony's web page here http://unlockbootloader.sonymobile.com
It says
" Important information
Please note that you may void the warranty of your device and/or any warranty from your operator if you unlock the boot loader. See your device's warranty statement for details. Additionally, due to the modified device software, Sony’s repair network will likely have to replace key components before it can properly test, repair and verify your device using our repair tools and software. Consequently, if Sony performs a warranty repair, Sony will likely charge you a significant service fee for the additional costs caused by your modification of the software."
Clearly it states MAY.

Although Sony logs the IMEI number, you still may not lose your warranty. It depends on which country you are in. For example : -
I had bricked my Xperia mini ST15i's touchscreen ( had unlocked bl the official way ). Just flashed stock rom with flashtool, relocked bootloader and gave it to Sony. In India, they didn't check a thing. I just told them that I had bricked it while upgrading to ICS with SEUS
Within a month, I got a new screen replacement absolutely free within my warranty period.
Yes could be a country issue too. You got lucky bro i guess, that they didn't check
In India all the cities got separate service centers or is it state wise?

I think that it is city-wise because the Sony guy told me that he had sent my phone to the local service center in a nearby city.
i read of several people that only relocked bootloader and they sent phone to service center without any problems
Depends what country your in as to what rights you have. In Australia i got my screen replaced with unlocked bootloader and no receipt. As Sony says this *may* void your warranty, it also may not. If something happens and is not directly resulting from flashing, then i would argue with Sony that unlocking the bootloader is irrelevant as the phone is defective.
My phone was fixed under even though Sony said no, i said OK ill contact ACCC, Sony said OK we'll fix it as a gesture of good faith. I assume good faith means 'damn this guys knows his consumer rights'.

Will unlocking the bootloader void my warranty?

Hi! I Just got the A2 Lite and would like to try some ROMs on It.
Will unlocking the bootloader void my warranty?
And if yes, Will re locking It get my warranty back?
Thanks in Advance
Unlocking the bootloader supposedly voids your warranty, but AndroidOne devices have no protection like Knox (which trips if you unlock BL), so there's no way of knowing if it's been unlocked before. Just flash the stock firmware via MiFlash and lock your bootloader before sending your device to warranty, voila. None of the roms I've tried work as good as the stock one though, I'd suggest rooting instead of changing the ROM. Have a nice day.
Very Good Answer Mastonpear...

If I lock the bootloader is the warranty still ruined?

I am planning to root my device and I was wondering is the warranty still ruined after locking the bootloader so my question is:
If I lock the bootloader is the warranty still ruined?
Well you don't lose it in the first place. No, unlocking the bootloader doesn't void your warranty.
if you restore MIUI rom and bring back phone to factory system you not loose your warranty, only if you leave unlocked bootloader and custom rom in phone you dont have warrant.
I believe once you unlock bootlaoder service center can check if you did it or not even if you re-lock it.

No, if you reflash the firmware, they can't check if you've unlocked it before (if you didn't unlocked officially in the first place).
Well most manufacturers (cheepo ones) do not implemented this kind of tech that persists data over a firmware flash.
Also, most of the time, they don't even check for this.
