UNLOCKING BOOTLOADER : What i'm going to lose. - Huawei P9 Plus Questions & Answers

Guys, i've been using many mainstream brands like HTC, Sony, Samsung, etc but im newb to Huawei.
For Sony device, im going to lose DRM keys for good after unlocking BL (not to mention backup TA) and many other features & functions like screen mirroring & camera quality degrade.
For Samsung, the well known Knox.
Im about to unlock my P9Plus but by reading this, quoted frm Huawei bootloader unlocking page, im abit scared of losing Leica image processing for instance.
4.Some functions will no longer work after you unlock the bootloader. For example, you will no longer be able to use Digital Rights Management (DRM) keys and digital content that you have purchased. Upgrading software using Firmware Over-The-Air (FOTA) or a microSD card may fail or your device may not function properly after upgrading.

Can anyone shed some lights?

I asked this before i unlocked my bootloader, as my previous phone was also a Sony.
I was told nothing would be lost, and from what i can tell, the phone still seems the same as it was out of box.
If you do notice anything, please let me know as well.
I haven't received any OTA update, but i can always download and update via SD-Card if i require.
Haven't tried playing any videos on the phone, besides ones that I've taken myself, but nothing i have contains DRM protection so I don't see any issues there anyway.

This is my 3rd Huawei Device after the P8 & Mate 8.
On all the devices I didn't notice any changes after unlocking.

how about screen mirroring & netflix/iflix HD. if im not mistaken netflix wont play HD movies if DRM is absent on device.

Hi, i wan't to temporary unlock BL only to de-brand my P9+. So i'll relock it after the operations. In that scenario, what happens to my warranty? If now I check the warranty status with Huawei services, i receive a message that the phone i regularly under warrenty until xx/xx/xxxx. If i unlock BL that message remains or will change in something as "NO WARRANTY..."
Thanks

If you somehow already have the bootloader unlock code (e.g. from DCUnlocker), then the warranty displayed on the website will not void, at least on my Singapore's VIE-L29C636. But I am not sure through if you get the unlock code via the official EMUI website. Your bootloader's state will become "unlocked", and if you do relock your bootloader, it will show "relocked" instead of "locked". Read my post here to revert it back to "locked" state.

[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.

Relocking bootloader and warranty.

I got my H9L 2 months back and had rooted it (and unlockedd bootloader). Im having a big battery issue battery drains too fast. I want to get it to service centre as waranty is not over.
I've read posts saying if I relock bootloader I'll get waranty back but some says I won't get back warranty even if I relock bootloader.
Can someone sort this out please
IF you've unlocked the bootloader and rooted the device you have no warranty in the eyes of the manufacturer, it states this in the terms and conditions when you get your bootloader code from them.
See when you unlock the bootloader you get a warning screen upon booting the device and relocking the bootloader will not get rid of that warning.
However have you tried to see if the battery issue is intact an software issue. I.e have you wiped caches, checked if an app such as Google assistant WhatsApp Facebook is running in the background. Do you have the same issue when booting android into safe mode????

That's strange. I've relocked it today after flashing compete stock using HuRupdater tool.
I'm not having the warning screen I had earlier when my bootloader was unlocked.
So does that mean I'll be able to claim my waranty now?
And I've tried different ROMs the issue persists.
If they ask if I've unlocked the bootloader(since I've given my product number they might know) I'll just tell that I took the unlock code just in case, as they were shutting it down and that I haven't used it. Well at least that's the plan
So will they know that I've unlocked it earlier if there is no warning screen? As I've told I have complete stock firmware including kernal and recovery like @Fredin_ told.
Please reply fast.
If your no longer showing that Warning message after going back to stock then you can try and claim warranty if you wish, however they might have other ways to finding out if the bootloader has been unlocked.
So put your claim in and see what they do, they will either honor the Warranty or not Honor the Warranty and give you a quote for the work.
Personally if i unlock my bootloader and root it i'd just put up with the issue as i fully knew that the warranty went when i unlocked the device.
But i will leave it upto you how you go about it.

Are you on CN or WW and does your fingerprint match the rom? You can check with device info hw from playstore, under system it'll show what the rom and fingerprint and product id are
Same problem
I have the same problem i unlock the bootloader wwith ASUS method and dont get updates in phone, need male manual... Is normal?
After unlocking your bootloader then your device will be blacklisted from receiving updates through FOTA forever. So a manual update must be done now everytime you want to update.
If you read description for the Asus bootloader unlock tool. You will see it states clearly that all updates through FOTA Will be permanently disabled once you unlocked your bootloader and that updates have to be manually done.
Here is a copy of the description.
Unlock Device App: Unlock boot loader
Notice:
Before you download, install, and use the Unlock Device App you acknowledge and assume complete risk to the quality and performance of this App, including but not limited to the following: once you activate the App you will not be able to recover your ASUS product (“Original Product”) back to original locked conditions; the Original Product with the activated App will not be deemed the Original Product; the Revised Product will no longer be covered under the warranty of the Original Product; the software of Revised Product will no longer be deemed the software of the Original Product and can no longer receive ASUS software updates; your purchased digital content may also be affected.
You also acknowledge ASUS does not guarantee service satisfaction to any Revised Product, including events involving paid service requested by you to be performed to the Revised Product.
Furthermore, such repaired Revised Product will not be covered under the warranty of the Original Product; the software of the repaired Revised Product will not be deemed the software of the Original Product and will not receive ASUS software updates.
It is strongly advised that you avoid activating this App unless you fully understand and accept the risks that may arise.

This has nothing to do with fingerprint or which ROM they use. Asus stated clearly on their bootloader unlock tool download page that once you unlock your bootloader there is no way to go back and all FOTA Will stop working. So everytime you want to update you must do manual update.

If you don't want to update manually, your only route is to flash a Raw CN rom and lock the bootloader to regain the ability to receive OTA updates assuming you are on a CN rom already. I can't confirm it will work since i haven't tried it but some users reported that they have regained the ability after doing that. Check other threads before proceeding. Good luck!

Can we relock the bootloader of the Xperia 1 ii?

As the title states, can an unlocked bootloader be locked again?
Yes

100% sure?
Sony Developers got back to me and said:
"We are sorry to say that it is not possible to relock the bootloader of your device after unlocking it. However, it is possible to get back to the standard Sony software using our Flash tool"
I may sell this device and would like to relock it

I'm not sure to what extent it can be relocked one day, but Sony phones generally have had a sort of fuse (meaning that even relocking _usually_ does not mean restoring to original state, unless you are able to do TA backups with a hack).
TL;DR: if you really want to resell it as locked, don't unlock it.

You can see on the Xperia 1, using fastboot you can relock the phone, and apparently this even restores DRM functionality (though no guarantees). But it will still have "YES" for "is ever unlocked" — so you'd be relocking it, but it would still be indicated in the service menu that this was once an unlocked phone.

Question Just bought this - Question regarding unlocking & root

I just bought this phone. It's actually quite nice and better than I expected. Paid 475€ for it brand new in a store here in Italy. I'm coming from the good old XZ1 Compact, aka the best phone ever made. This seems to be a big (too big, tfw no phone under 5.5) improvement over it.
That being said, I was wondering how does Asus react to their phones being unlocked. I come from Sony which does not like unlocking, in fact on the XZ1 and XZ2, unlocking was permanent and you lost drm keys and stock features fOrEveR. How is it on this one? Does it void the warranty forever? Do you lose stock features after unlocking? Can you relock the bootloader and go back to full stock eventually?
I googled and searched all over but I find conflicting and contraddicting informations about this, on top of the usual ****ty websites with ai generated copypaste guides.
Thanks in advance.

>> Does it void the warranty forever?
I think so
>>Do you lose stock features after unlocking?
I did not find anything that did not work anymore after unlocking (but I tested only the functionality that is important for me ....)
>>Can you relock the bootloader and go back to full stock eventually?
I don't know if you can relock the phone but I doubt it.
You can reinstall the Original ASUS Firmware and it still works like before. You can also install the updates for the original OS manually (I did not test if OTA still works)
regards
Bernd

To add to bnsmb's response,
When the phone is unlocked, some apps will not work, like google pay for example, but the bootloader can be relocked with one fastboot command and you will get all features back (except OTA updates from the settings, you will have to update manually)
(It is not recommended to relock the bootloader when not on the Stock Asus ROM)
To relock, simply type these two commands
adb reboot bootloader
fastboot oem asus-csc_lk
reboot
The phone will prompt you to do a factory reset when booting

Yes, I have tried it once, but some people reported it does not work depending on the version, I tried on Android 12 and it worked the first time (and on android 11 but that was the first unlock a while ago)
Thank you for the info! I can't find the official manual or faq though, even from the link bnsmb provided :\
That's why I asked here in the first place. From what I can tell after looking through this info, they will know you have unlocked from the imei, considering their unlock tool talks to the mothership before doing the deed. It is still unclear if they will respect the warranty period even after unlocking. I don't care about asking them for support on an unlocked phone, I just want to make sure it will get repaired or replaced for free (in terms of money and hassle) if I get a defect down the line that is unrelated to the unlock, such as a hardwre failure or assembly defect.
Anyway, it seems the only way to shed light on this mystery is to ask Asus themselves. I will report back as soon as they respond to my questions.
Warranty with unlocked bootloader
The warning text of the unlock app links you to the Warranty Policy for ASUS Phones, where the relevant part reads:
6. Exclusions from this limited Warranty Service
[...]
(m) Unusability or damage to hardware of the product caused by installing and using any kind of the Unlock Device App, which is a utility that will unlock your product’s boot loader but will render the warranty null and void.

So yes as is usual, they will try to use "you having unlocked your bootloader" as an excuse to not repair their broken phones under warranty.
But, depending on your local consumer protection laws, there is a good chance this is actually illegal. In the EU for example, during the 2 years of required warranty THEY have to prove YOU that the defect was ACTUALLY CAUSED by you messing with the phone's software - which generally speaking they can't because it wasn't.
If you haven't seen it i recommend this thread for some details of people who have actually been in that situation - from what i saw after a quick glance through, 3 out of 3 people there got their unlocked&rooted phones replaced under warranty in the end, even it it took some effort to convince the support...

The linked thread does tell that one person was successful with the ASUS support, "all other" unfortunately not, see e.g. post #6.

Reading posts #31 and #38 i am pretty sure the person from post #6 did not have to play in the end as well. I also can't see anyone else in there who reported they tried to get unlocked phone replaced and didn't
Ups my fault, I have not seen the posts after #20 ... So it seems the warranty (given by law) is not void but the guarantee is (given by the company).
Anyway, in the meantime, Asus replied to me saying that if you unlock you lose your entire warranty no matter what. I reiterated, asking if I will also lose my right to a free repair for issues totally unrelated to the unlock, and they said yes, you will lose every right to repair.
So that is the official stance!
Too bad, I'm still in the return period so I might just get rid of it and hunt for a Pixel 5. Kind of sad though, the phone performed pretty well for me so far. But I need muh root and eventually LineageOS...
