No it doesn't

Right now I'm using Beanstalk ROM but I want to go back to stock due to battery issues but I can't use flashmode anymore.
If I flashed a stock based ROM will it void warranty in DE

You already invalidated your warranty when you unlocked your bootloader.

That's an interesting page. Thanks. It's useful to me, as the UK actually is part of the European Union and has been since 1973.
I have to ask, though, if you're already aware of this stuff, then why are you asking here?
The thing is, Sony would probably argue that it's overridden by the fact that you agreed at least 3 times that unlocking your bootloader may invalidate your warranty during the process of retrieving the unlock key from their website. Even though statutory rights cannot be overridden in this way, that hasn't stopped warranties being denied for no good reason before. This is a moot point though, as long as you restore your TA partition before taking your phone for warranty repairs.

What happens if I flashed a stock based ROM and relocked the bootloader and tried to install an OTA update from Sony

The OTA will almost certainly fail, as most OTA updates perform a check to see if /system has been modified in any way. If this check fails, then the OTA update will not go ahead.

[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.

[Q]Bootloader relock

I don't understand one thing. Even if it's possible to completely lock back the bootloader, what is the point, since htc would know that you have already unlocked the bootloader using their bin file. Wouldn't it still void the warranty even if you relock the bootloader.

It would seem that it would, but their disclaimer states "may or may not" void the warranty. If it is "Locked" with no "Tampered" there is always the possibility that they may not look or search to see if you unlocked the bootloader. I would rather have it look as if it was never unlocked than leave it unlocked and remove all doubt!

Also, is it worth flashing or custom roms here are as good as stock. I just don't like sense, specially the lockscreen on 6

flashing custom rom worth it if the stock rom doesn't fit your needs. You'll have to read some custom rom threads and try a few to get an idea of what rom you prefer as "which rom is better" discussions are not allowed in this forum.
For your bootloader question, If you send back the phone for warranty repair, and the bootload is LOCKED (not relocked) and everything else is stock, there is 99% chances HTC will honor the warranty without any question. And even if they know that you have requested an unlock_code.bin from HTCdev.com , how are they supposed to known if you have used it or not? Maybe you have requested a code, and you have changed your mind.... HTC said that unlocking the bootloader may void warranty, not that requesting an unlock code void the warranty

I see. On a side note, can i unlock-root then flash a rom (4.2.2) and then s-off? even though i'm on 4.4.2 at the moment.

yes you can unlock, root and flash a rom. if you want to s-off you might be able to do it using firewater s-off. If firewater fails, then sunshine should works, but sunshine is a paid exploit, don't remember the exact price, I think its around 20-25$. S-off can also be achieved with a java card (fonefunshop.com)

exactly....
firewater may not works (50-50) but afaik, sunshine should work (not tested it myself, better to check the official thread). In last resort, the java card method from fonefunshop.com will work. firewater is free, sunshine cost 25$ iirc and fonefunshop.com cost £14.99 + shipping to UK
Sunshine works on all m7 phones. You may need a stock Rom or at least stock kernel but it will work. Try Firewater first but most people don't have any luck with it these days

Guess i'll stay stock until a hero emerges and updates firewater.

[Q] Void warrancy and root without BL unlock

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.

Warranty void post root?

Hi,
I'm trying to choose between buying a K20 Pro (when it releases in India on 17th) or a OnePlus 7.
I remember that that the warranty of older Mi phones would not be considered void if it was rooted or only the bootloader was unlocked. If I remember it correctly, it would be voided only if a custom ROM was flashed.
So, is this the same scenario with the K20 Pro? What can be done without voiding the warranty?
Thanks
Isn't that the case for any make and model of smartphones?

I don't think so. Rooting voids the warranty of most phones. Xiaomi, OnePlus and another OEM were the only ones who allowed rooting without voiding the warranty.
Also, the info I remember is from 4~5 years ago, so I might be wrong.

Any idea about the K20?? Will rooting it voids it's warranty too?
Unlocking the bootloader doesn't, rooting will.
Unlocking or rooting shouldn't void your warranty. Also I'd given my RN4 for replacing the board and I had a custom ROM in it but I still got it replaced under warranty. There's no official statement but you can always revert back to a stock ROM before giving it for repair

Question Hey , my phone is under warranty, if I flash a custom rom is there any way I could claim my warranty just in case ?

You can install any custom rom but for the warranty a stock rom must be on it.
It doesn't matter if you've tried custom roms before.

Hi Anmol150704,
What NOSS8 said basically.... You can do what you like with the phone once you get it, but for the warranty to be honoured.... you need to return it to stock before claiming or they will blame the custom rom for the issue. So as long as you device is functioning enough to return to stock, you should be ok.
And unlike Samsung, there is no Knox/Triggers that I am aware of that they can tell if its been flashed or not. Which is the main reason I came away from Samsung, due to the forced compliance to stick to stock if you wish things to continue working or claim a warranty.
Cheers, Lister
But don't worry if your phone is dead with a custom rom and of course you won't be able to reinstall a stock rom, there is EDL mode but using this mode the warranty is over (software problem only, not hardware).
By following the flash instructions and informing it beforehand, it is quite rare to destroy the phone.
Xiaomi is solid.
All clear , thanks a lot
Yes you can, I recently reverted back to stock miui 13 from Evolution X with the help of Mi Flash. All you have to do is to download Usb drivers, Your device TGZ Firmware and Mi Flash Tool. There before flashing you can select lock and clean/flash and the device will be sent to locked status once again.

It does depending on the reseller or where you bought it from. Just DON'T let them now, ever

Sellers buy from Xiaomi, the warranty conditions are set by Xiaomi, of course, the warranty period is different depending on the country.
If there is a beta version for your Xiaomi model, you can unlock the bootloader with Mu unlock which, as a reminder, is an official tool provided by Xiaomi.
If you buy a Xiaomi in one country because it is cheaper and you used and lived in another country, the warranty will be denied by Xiaomi.(common case where the seller refuses the guarantee and send it to Xiaomi.).
