Has SafetyNet killed development for A71? - Samsung Galaxy A71 Questions & Answers

I'm guessing Google can use hardware-backed key attestation on this device...?
And that means we're all screwed, right? Who knows what apps won't work, so it's not worth unlocking the bootloader.
And the chance of finding an exploit that doesn't rely on an unlocked bootloader is bugger-all, right?

Features lost during unlocking

Do I lose any features like on xperia phones when unlocking bootloader?
Your device will be wiped when unlocking and (unless you take measures to hide it) an unlocked bootloader will trigger SafetyNet (if you care about that).
Other than that, no worries.
Does 3T have any tamper flags and do they affect android pay?

No
No tamper flags. You won't lose your warranty by unlocking the bootloader or rooting a OnePlus device. Gonna quote their official faq:
"The technical process of rooting or unlocking the bootloader does not void the warranty of a OnePlus device. However, we strongly suggest for you to only root or unlock the bootloader of your OnePlus device if you are confident in your understanding of the risks involved.
By accessing resources regularly unavailable to the software, you may damage your hardware during or after the procedure. Such damage is not covered under warranty. In warranty handling, we will first need to verify that any faulty behavior is unrelated to rooting / unlocking."
Unlocking your bootloader affects AP in the way that it'll trip SafetyNet and AP won't work. You'll need to use some way of hiding it (kernel, Magisk, etc).

Questions regarding rooting & Unlocking BL

Used to root etc on old phones, taken a long break from it all but I have sent a request to Huawei to get my unlock key for my P10 VTR-L09C440, however I have a few questions I hope can be answered.
1. Can I re-lock my bootloader after unlocking, and if so does it say anything like "bootloader relocked" or anything like that or is it completely back as it was?
2. Can I use restricted apps (I know I couldn't use Barclays and I think one of my betting apps and Google Pay were restricted), has this changed now or can Magisk etc actually hide BL unlock / root / whatever it is it doesn't like?
I would like to know that too

1. No, when you manually relock, the bootloader status is "RELOCKED". To lock the bootloader you need to use HWOTA8, FunkyHuawei or FirmwareFinder and update to the newest version. Both will cause factory reset.
2. When you rooted with Magisk most apps with Root detection will work, when you enable "Magisk Hide". I use it on my bank secure tan app and Mario Run without any problems. Some friend are using Magisk Hide with other banking apps without any problems, too.
I haven't rooted and unlocked myself but I read about an important part of the process.
First of all you have to enable oem security in developer options, otherwise you risk the FRP lock.

If I'm wrong, someone please correct me.

OK great, thanks for the info. I have actually finally just heard back from Huawei so code should be imminent. Unfortunately my battery as stock seems to be awful so I need to try something to make it last a day at least.
Does Magisk hide make Android Pay work too?
I think I'm right in thinking that banking apps and the like often check bootloader status rather than just root. I assume Magisk doesn't hide this?
If I go back to stock and relock bootloader, will the apps also still register that the bootloader has been unlocked and still not work?
TIA

Can someone confirm this please? Does anybody use Android Pay and Barclays confirm Magisk makes it still work with Bootloader unlocked?

Without a certificate problem google pay?

Hello
I would like to use google pay, but the application informs about phone modification and can not be used.
The phone has unlocked the bootloader, I do not have root. I am on the CLT-L29C432B131 using the HuRUpdater method.
In google play information - no certificate. Is this a problem and how to avoid it?
Same issue here
Unlocked bootloader and now Google Pay isn't working
Unlocking the bootloader breaks safety net. Relock it & you should be ok.

One Step Root

I have an unlocked SM-N9600. Is there a one step method (like an app you install, and it roots the phone without a computer) available?
No there isnt since rooting requires bootloader unlock and unlocking the bootloader will permanently disable Knox forever which means Samsung pass, Samsung pay and secret folder will be disabled since they require working Knox chip to function and even encryption might be disabled aswell

[REQUEST] DRM info after relocking bootloader

From the title: I'm kindly requesting to check DRM status (DRM Info app here) after unlocking bootloader and after relocking the bootloader.
If possible with a screenshot otherwise I'm interested in knowing if Widevide DRM Level goes back to L1 after relocking and how System ID changes with L3 and L1.
Furthermore t's useful knowing if you also flashed a custom rom and/or blew Knox Fuse in some other way.
Disclaimer: do not unlock your bootloader just to do this check. This request is meant for people who already have bootloader unlocked by their own means.
There is a screenshot example attached to this thread, stock locked A71 never before unlocked.
You keep your DRM keys when unlocking bootloader on A71, so Widevine stays at L1.
No TWRP installed, only magisk.
oh, that's actually really good news.
My previews experience with Widevide DRM was a permanent keys loss.
Thank Samsung for this approach.

Not really. I rooted by mixing magisk into android and then flashing it with odin. There are some tutorials on youtube, showing how it's done.
