disadvantages of unlocking the bootloader? - OnePlus 7 Pro Questions & Answers

Hi guys. I was planning on unlocking the bootloader. But apparently widevine L1 doesn't work on unlocked bootloaders. Is there any other disadvantages of unlocking the bootloader? Some apps on Google play store are blocked and it might break safety net. I know that. I just want to know if there's anything else that I need to be worried about.

Is root without unlock possible?

I just wondered as a new Honor user wether root without unlocking the bootloader was possible, or if anyone is looking into to it at all?
Perhaps dirtycow or other ways?
Thanks in advance
I think that this is not currently possible. But the return of the original factory state is not a problem, see this topic here & here.
why do you even want to root without unlocking??whn unlocking is the easeier one than rooting...:good:

u should unlock but don't warry almost 90% of country's unlocking will not void warranty for huawei policies
Warranty issues and letting HW know that I've unlocked the bootloader.
Coming from Sony's previously you would lose DRM info for the camera and screen and audio tech if you unlocked without saving a TA partition.
Asume thats not the same with HW and its only a matter of them refusing to support you if you unlock?

Pretty sure he knows that. That is why we're interested in rooting the phone WITHOUT unlocking it...

Root on locked bootloader

His guys just got the xzp and wow what a phone my only concern is root I have a locked bootloader and it's not unlockable but to be fair I've never unlocked a Xperia bootloader due to loosing drm keys etc
So my question is will we be able to get root on locked bootloaders like we did with past Xperia phones or are we stuck unless we unlock which in my case would mead no root ever :crying:
Thanks
Probably not would be my guess. You still need to unlock bootloader on previous models such as XZ/XZS.

Darn I love this device too but to never be able to have root might be a deal breaker
In service menu it says unlock bootloader allowed no but in developer options it give me the option to unlock the bootloader does this mean it's possible for me to unlock the bootloader

But I cannot unlock the bootloader I was hoping for a root without unlocking the bootloader like the z3 which was my last Xperia device
One question if I stay with the xzp cam I at least flash the latest stock UK unbranded room with a locked bootloader so I can get rid of my carrier stuff thanks

Like always, if a security breach is found on Android that allow getting root access, it will be possible to backup the DRM partition, then after if you like, unlocking the bootloader and then restore your DRM partition.
At least, it finished like this for the Z5, but you had to downgrade to Lollipop to get root access.
AFAIK, there is no known way to get root on Nougat today.

So there is the Dirty Cow exploit that seems pretty pervasive and promising.
https://forum.xda-developers.com/general/security/dirty-cow-t3484879
EDIT: Nevermind I'm an idiot, I didn't realize the dates on dirty cow.
Question still stands though, do we know if there is anyone on the XZ Premium working on it?

I don't think so, there will be more involved ppl when XZ1 will be released, since it's the same specs

It's not possible anymore. You really need to unlock the bootloader in order to root. Something about patching the kernel.

L1 DRM with unlocked bootloader

Currently I am on stock OOS with a locked bootloader and I heard that when you unlock the bootloader the DRM gets downgraded to L3.
Is this correct and does it go back to L1 if you relock the bootloader?
Also, is there a hack of some sort that allows the device to continue using L1 DRM with an unlocked bootloader?
L1 not working
I unlocked bootloader and then relocked it again but it is still showing L3 what should i do

But there is no way to get L1 with an unlocked bootloader?

I'll probably stay with official OOS for the moment anyway, but thanks for the info
So, has anyone tried OOS 5.1.6 and the fastboot locked bootloader bug to backup and restore the DRM keys while locked or to use Magisk root while on 5.1.6 locked bootloader and see if L1 keys are retained?

There's another thread in this forum that poses that exact question. No one to date has succeeded and I'm not sure it's even possible using the 5.6 boot exploit because Widevine calls home every time it proxies protected content.
I suggested chipping in on a bounty that would go to whomever can find a way to get L1 on a OP6 with its' bootloader unlocked using a method that would be successful with ROMs based on OOS, LOS and AOSP. I figured a little financial incentive could provide some motivation, but nobody else seemed willing to contribute. ?

Since I need L1 on an unlocked bootloader, I ended up getting a Moto Z3 Play despite it being slower since Widevine L1 stays regardless of bootloader state or Magisk being installed.

Widevine L1 and unlock bootloader ; still no workaround as of today ?

Hello ! I just wanted to know if, as of today, there's still no way to recover Widevine L1 with an unlocked bootloader (except by relocking it, of course )
Thank you !

Nope still not possible and probably never will be unless OnePlus allows it.

Widevine Security Level after unlocking bootloader/root

UPDATE 2020-11-12:
With the latest 11.0.3.4 update, Widevine stays at L1 even if you unlock the bootloader or root!
Hi all,
I have seen one comment that someone rooted the 8T and widevine becomes L3 instead of L1, unlike the 8/8 Pro.
Can anyone with rooted 8T or bootloader unlocked 8T comment below what is your widevine security level? You can use the app here to check: https://play.google.com/store/apps/details?id=com.androidfung.drminfo&hl=en
Please include your 8T model (e.g. KB2005), whether bootloader is unlocked and/or your phone is rooted. Thanks in advance!
8T model KB2005

Rooted
It has security level L3

Phones with Widevine L3 cannot stream HD content from many DRM protected services such as Netflix. You can stream max 480p.

When I got my phone and set it up, I had updates from the play store. Netflix was one of those it updated.
I unlocked my bootloader and later on when I tried to use netflix, it promoted me I needed to update the app. When I said ok. It took me to the play store where it said Netflix isn't compatible with my device.
Installing an apk for netflix found on the web gets me netflix, but it still doesn't show in the play store. Plus maximum playback is SD only.
Unlocking the bootloader changed my L1 to L3.

Have you tried relocking your bootloader to see if you go back to L1?

Enabling MagiskHide, then clearing cache and data for play store allows netflix to show up in the play store. However still has the SD issue in the netflix app.

I had this problem before being rooted, so never had magisk to do that. But will give that a try now.
Also. Just doing a quick Google search, there are a few things I've found out. The persist.img apparently holds the DRM keys. If this was changed or damaged it sets Widevine to L3.
I don't think by unlocking the bootloader or rooting that it touches the persist.img, so not sure if that has anything to do with it?
Also, by reading some xda threads and threads on the OnePlus forum, it seems like a system update can fix the issue and you still be unlocked\rooted. Seems to be the case for op8 and some older ones

I don't think it has anything to do with persist.img (that one is more related to the fingerprint). On OP8, OnePlus released a fix and solve the issue, but for older phones like OP6, as long as you unlocked the bootloader, it's permanently Widevine L3 even if you relock it. This is what I am worried about.

Once unlocked, you can't go back to L1. Qualcomm has a "feature" called QFuse, a microscopic fuse on the SOC. It blows if the device is unlocked. That breaks the chain of trust.
Is this something that will affect warranty? Like Knox on Samsung?
Hello! I did what you wanted me to do. I'm rooted with Magisk, Magisk Hide turned on for the DRM checker, and I'm on the latest 11.0.1.2.KB05BA (EU) Widevine is L3.
Can't open the picture

Nah. Xiaomi and Pixel devices retain L1 on bootloader unlock, even though those devices use Qualcomm chipsets too. So it's definitely not that.
After unlocking the bootloader I was unable lo load Netflix.
Then I have relocked the bootload and Netflix works in full HD

This is DRM info reports now after relocking the bootloader
