[Q] Void warrancy and root without BL unlock - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hi to everyone!
I just find that it's possible root our phone without unlocking the bootloader (and lost the dmr key).
What about the warrancy? If I root in this way I'll void it? or what?
Thanks in advance

Once you unlock your BL your warranty is essentially gone.
Because you can't undo the process (unless you backed up your TA partition).

I'm not sure I understand - the OP asked if the warranty will be voided if he roots the phone using the newer method without unlocking the bootloader. Or do you simply re-lock it later with this method and the warranty is still voided?

That's why I said that the warranty will only be voided if you unlock your bootloader. All other things like root etc, you can just revert and Sony will never know it.

[Q] Will unlocking through Htcdev void my warranty for good?

If it matters, I live in Europe. Anyways, I bought a One yesterday and I've been browsing around, seeing how it is with flashing roms and stuff. I did have a Nexus One a few years ago, though. If I unlock my bootloader through Htcdev, is my warranty lost forever? Like if something happened that wasn't caused by me tampering with the software, would I still get warranty repairs or would they say no because of me unlocking?
I previously had an i9300 which I flashed roms to like crazy but it was easy going back to stock, making it look like I had never even rooted the thing. The bootloader didn't had any sort of lock.
I have searched and looked around but it's unclear whether the warranty disappears or not.
it may void the warranty but if its a defect they should still honor the warranty. but s-off is right around the corner once thats available you can go back to complete stock with no evidence of tampering
How so? I thought that when unlocking (through htcdev) they get some token from you that says (Hey I've unlocked derp derp). Kinda like when unlocking asus tablets?
Or do you mean circumventing the bootloader lock by flashing a custom hboot?

well just unlocking doesnt actually void the warranty. its when you have the tampered message you might void the warranty but with s-off you can get rid of the tampered part

[Q] Cyanogenmod on XZ

So, I want to install Cyanogenmod on my XZ, using flashtool to unlock the bootloader and doomlord's expliots to root.
However, won't rooting first re-lock the bootloader? Or unlocking the bootloader remove root? Both things wipe the everything, so... Help lpease?
Whatever you do, be sure to backup your TA partition before you unlock your bootloader: http://forum.xda-developers.com/showthread.php?t=2292598. To do this, you first need to root your device without unlocking your bootloader.
Otherwise you will lose your DRM keys permanently and you will never be able to use certain functions (like Mobile BRAVIA Engine 2) anymore, not even if you relock your bootloader and restore to a stock ROM.
Please also note that by requesting a bootloader unlock key from Sony, the IMEI number of your phone gets blacklisted and your warranty is void.

Go to http://unlockbootloader.sonymobile.com/unlock/step1. At step 2, you need to agree with the following legal terms before you can continue:
I acknowledge that use of the boot loader may void the phone’s warranty.
I acknowledge that, if Sony does perform any warranty repairs, Sony may charge a service fee for additional costs associated with the modified software.
So if a phone with an unlocked bootloader (or relocked bootloader) needs to be repaired, your warranty may be void, it's completely up to Sony to decide about that and they have the legal right to charge you for the repair because you agreed to those terms. If that's fine with you, you can continue to unlock your bootloader and flash a custom ROM like CyanogenMod. I myself would only consider this after official firmware updates have been discontinued.

Damn, so you say if i request an unlock key for my bootloader, but never use it. Do it still void my warranty. I mean, maybe some people change there mind after they request the unlock key and never use it to unlock the bootloader.

You should only request the key if you're going to unlock your phone. Sony has no way to check if you unlocked your phone and then restored a TA backup, so that's why they require you to register your IMEI number.

Anyway, if Sony refuses warranty, you could go to court and argue that you only requested the key, but didn't use it. Then it's up to the judge to decide if requesting the key (and agreeing to those terms) is enough evidence or not. However, I think most people won't go to court and just pay for the repair or buy a new phone. What I meant to say is: just be careful and think twice before doing such modifications
I think Denmark have pretty strict rules to protect the consumer, so I really doubt that Sony would get away with applying these rules here - but this definitely makes me not want to unlock the bootloader before I have seen Sonys 4.4 firmware.
Thanks for the info!
That being said, I think Sonys stock ROM works really well.
I'm rootet, running SwiftKey, Handcent SMS, Aqua Mail, HD Widgets an Apex Launcher Pro. I get 3 - 4 hours of screen time on stock settings.
I have no reason to really want another ROM.
Had it been a Samsung or HTC device I would have needed to strip the device of all the bloat
ware and get rid the massive battery drain, caused by wake locks from the manufacturers ROM.

There is no flash counter to worry about with Sony phones...... Once you have unlocked bootloader your warranty is void even if you relock it.
Rooting does not void warranty.

Why?? I will relock bootloader, restore DRM keys, flash stock rom and will have same system when was when I bought the phone.
That I have "order" unlocking bootloader key doesen't mean that I did it.

Yes. But when you relock it, restore TA partition and flash stock there will be no sign that you have done it.
You may be correct... but most people will say that unlocking bootloader well void the warranty.

Yes, but you have given the imei of your device to Sony in order to get the unlock code. So if something happens to you phone and you get it at a Sony repairing center, the first thing they do is to read the imei from your device and check if it is in there database

And so?? They also have my phone in database when I bought it. I dont understand your reasoning.
I have buy a bulb yesterday. Just in case. Thats mean that I have to immediately change it??
No.
And for confirmation.
I ave do it twice.
First with my old LG GT540. (Stock -> root -> cyanogenmod (warranty off) -> flash stock without recovery, and fastboot (warranty on)
Second. Xperia SP (Stock -> root -> bootloader unlock (warranty off) -> existenz -> relocking BL -> Restoring TA -> Stock ROM (warranty on)
Both of them was rapairing without aditional costs.
End.

[Q] Unlocking?

I'm trying to figure out exactly what you lose when you unlock Z3(C).
So far I've discovered that:
- Sony has a webpage that allows you to unlock your device
- Unlocking your device will void your warranty
- Unlocking is the only known way to get root (at least right now)
- Unlocking your device will kill the "TA partition" that contains DRM keys
- Loss of the aforementioned DRM keys will cause some stuff to stop working
I found a huge thread on backing up TA partition for older xperia devices, but no good information RE: what exactly you lose if you wipe out the DRM keys by unlocking.
Do any of you know definitively: what the DRM keys are for and what you lose?
As an aside - it looks like backing up TA partition is only possible before you unlock bootloader and if you've rooted your phone (so probably not possible on Z3C until someone finds a working exploit to get root with a locked bootloader).
Thanks in advance for any insights.
I don't think there is a definitive place which says exactly what you lose by unlocking the boot loader but judging by what people having been saying after unlocking the Z3C and other Xperia phones on 4.4 it seems like the answer is nothing. Nothing is lost on the software side at all.
On the z1c I neglected to back up the TA partition. And apparently lost native mirror cast and some camera features when I rolled the device back to stock.
Back up your TA partition before unlocking BL... If not for the I'm tact features turn for your warranty!
http://forum.xda-developers.com/showthread.php?t=2292598
Those that have rushed into unlocking the BL without backing up the TA partition risk voiding warranty I'm afraid.

Problem is, you need root to use those backup tools... So we would need a temp root exploit to backup before unlocking. But from what I've read so far, it doesn't seem like you lose that much, if anything.
I am also curious about this as I need root access but would like to preserve the warranty. Somebody else has also started a thread with what breaks with unlocking: http://forum.xda-developers.com/showthread.php?t=2890936

Most important consideration is your warranty such if your happy to lost it then unlock your BL.

It's not that definitive that you will lose warranty. Sony says it may void your warranty. Known issues with the specific model or batch, or other hardware problems that could not be caused by flashing custom ROMs/kernels will most likely still be covered.
http://www.phonearena.com/news/Sony...oader-unlock-tool-voids-your-warranty_id32972
I myself have sent in my Xperia T twice since unlocking the bootloader and on both occassions it was covered by the warranty.
Mind you, I did relock the bootloader and flash a stock FTF before doing that.
Flashtool has a function to relock the bootloader
http://www.digitalinternals.com/mobile/keeping-warranty-intact-sony-xperia-unlocked-phones/264/
I don't know if this works on our phone already, maybe someone who has already unlocked would like to try?

Can it be rooted without unlocking the bootloader?

Can this device be rooted without unlocking the bootloader? I don't want to unlock the bootloader since I want to keep my warranty.
It is useless because regardless of device and brand, any procedure of rooting or going to even partially modify the official system components will void the warranty ... temporarily! You can unlock your boot loader. The question is ifi you can unroot and reblock the bootloader ................ if you can do same it's ok!
You can unroot and relock your bootloader without any trouble.
Off course, personally I only use SU from @Chainfire to root, I can't report about other's methods.
I have unroot and downgrade for reinstall the single variant sim firmware(my 2 p8 is single sim but I use one with 2 sims) , and relock my bootloader for sending it to Huawei for warranty coz of a hardware issue , no trouble.

Yeah you can root with kingroot . but its not good once you root with kingroot you will not able to UNROOT IT. Do it in your own risk . better do by unlocking bootloader and flash thru adb. and supersu (chainfire) is safe and efficient.
