Bank nfc app problem after re-lock bootloader

Hi, I have a problem after re-lock and factory reset. My bank app, paylib, which allows to pay with phone using NFC, recognize my phone as a new one. The problem is that if I choose the"new" terminal for installation it doesn't work and installation aborts. Just message : error #tech. 03000# at the end. Is it because I relocked bootloader?
Can anyone help me?
Thanks!

I have the same problem with Google Pay after installing Leedroid.
I can add my card but when i click verify card the app glitches and force closes.

It's not working not because of your relocked/unlocked or locked status, it doesn't work because you probably messed with the OS.
See if you can find a ruu and flash it to be sure you are completely stock. If you had at some point rooted your software and unrooted it by the uninstaller it leaves traces. Bank apps are very bad when it comes to root.

I never changed the os, I was completely stock. I unlocked my bootloader only for a maybe change of rom.

Strange. Because i know several banking apps are even working on a custom rom rooted via Magisk. With the needed modules they are able to use the applications without any strange behavior.
Not sure where your issue lies then.

I now have a custom rom, maximus hd with root (magisk) but I still can't get nfc pay to work, my bank app recognize root even if I hide it from root with magiskhide.
What modules are you talking about?

settings > apps > *your bank card app* > storage > clear data > reboot
Your bank card app should work after that if you have it hidden with Magisk.

Re-Lock Bootloader?

So a little while ago i tried to root my S9, it did not go well so i flashed stock firmware in Odin and everything started working fine again.
Yesterday my bank finally started supporting Google pay so i went to add my card but it said i was still rooted. After some searching i found out the my CTS Profile Match was failing because i unlocked the bootloader, is there anyway to relock the bootloader to pass safetynet?

on developer options you can disable bootloader unlock but its gonna factory reset your device.

that knox how much i HATE it....
anyway i have the same device and i did that...
your knox is already 0x1 samsung pay and some other features for example s health you can not access it anymore via the original apk and firmware if you don't have root..
google pay will work just fine after you gonna lock the bootloader.
and if you want to use gpay with custom rom you must delete google play services and install a version that starts from 14. something and hide magisk but it works just fine
aparently

Relocking bootloader

To use Google Pay, you need to pass Safety net.
It is not related to bootloader.
And relocking bootloader without losing any data is possible if and only if you did not flash any custom mods like recovery , kernel ..As it validates md5 checksum

You don't need to re-lock the bootloader to use Google Pay. Install TWRP as your recovery and then install Magisk!

You will need to relock the bootloader then, you may lose data. Just back up everything first like pictures and videos. All your apps will re-download when you sign back into Google

Like the title said i have an redmi note 8 pro with ANDROID 9 stock firmware rooted but while im try to change the name of magisk

Someone can help me pls?

You won't be able to get around the CTS false flag now without completely removing Magisk. The requirements have changed recently.

Use the uninstall feature in the Magisk manager app and reboot. If it still fails the safety net pass, I think you need to lock your bootloader which is dicey. Might want to wait for someone else to confirm the steps as it's unique to your ROM version and may cause a hard brick, but typically flashing an unmodified MiFlash tool ROM and then locking the bootloader after should do it.

You can get around it by using the "MagiskHide Props Config" module and using it to change your devices fingerprint. At least on Android 10(Pixel Experience, CFW, Used Pixel 4 XL fingerprint)

Must only work on CFW then.
My bootloader is also unlocked.
My exact load out is:
CFW Pixel experience
CFW TWRP
CFW Zentisu kernel
I used the emulate device option in the props script and set it to Pixel 4 XL.
I can confirm that Netflix and Google Play works. At least on global with My setup.

Yes, I have a Redmi Note 8 Pro(Global)
Android 10 CFW (Pixel Experience)
CTS Profile and basicSec are True, I've already stated that GooglePay and Netflix both work.
No, I haven't, as I don't see a reason too. If it's to hide it from other people then this can be accomplished with a 3rd party launcher, otherwise I don't see the point.
All of these questions have been answered in my previous posts aside from renaming magisk.
Everything you need to know about CFW and flashing custom ROMS is available in the Redmi Note 8 Pro megatread I advise reading it in its entirety and reading the entire comment chain(i know it's a lot buts it's important) before attempting anything, and everything else I'm using is in the Development ROMS, KERNELS, Etc. Section.
I can't really comment links right now as I'm in using the labs app.

Not able to add a visa card to Google Pay when unlocked

Hi there,
I'm in contact with google support to add a visa card to Google Pay. After several issues finally sorted, I have now a message saying I can not add a card because my phone is altered.
Is the fact that my phone is unlocked won't allow me to use Google Pay / NFC feature?
Thx guys

I managed to make work my banking app and Google Pay with these steps:
1. Enable Magisk hide + enable hide for Google Pay and Google Play services
2. Repackage Magisk Manager app (you will need to enable installation of apps from USB source in system developer settings)
3. Force basic Safetynet test by installing MagiskHide Props Config and selecting Mi 10T pro as a phone model (as a bonus, AR will work too)
Reboot phone and it should work now.

Hummm... after some research, it looks like this method won't work for a long time. Can I unlock my device for the time being? It's unclear how I can do it...

Maybe it will, maybe it won't.. There is a secondary method involving modification of Google Pay sql database which might work for a longer time.
Anyway, to unroot your phone and to pass safetynet you'll need to reflash whole ROM and lock the bootloader (make sure that phone is working before locking).

My Google Pay NFC visa was working after passing safetynet on magisk but stopped working today. Tried to unroot but still got the same error.
I didn't update the app at all so I'm guessing on the server side they did some changes to detect for root / custom rom /unlocked bootloader or something.
Now I'm gonna re-root since removing it didn't helped. Lol

Is a factory reset will do?

Safetynet will fail with unlocked bootloader, you need either unlocked bootloader + Magisk hide + basic Safetynet test (can be forced with using for example Mi 10T pro as a phone model), or completely stock rom with locked bootloader. Mine Google pay seems to be still working (at least app doesn't complain about anything ).

All versions are 5G - check which MIUI version exactly do you have now (settings->about) and then download a ROM for the same region.

Long story short. After bricking my device (XiaoMiTool V2 hit it hard), I managed to get it back and flash a Fastboot ROM (through XiaoMiFlash).
And Google Pay still say I can not add a Visa Card because my Device is rooted or is altered in a way. I downloaded a root checker and it says I'm not rooted... WTF???

"Clean all and lock"

Yes, flash all and lock is the right script. But it's a good point to lock your bootloader only after you are sure that your phone works.
When you are sure that you are with a fresh stock ROM, reboot to fastboot mode and issue command:
" fastboot flashing lock"
Beware, it will erase your data and if you by any chance have modified boot or system partition, you will brick your phone and it must be revived by EDL mode.

I tried the command but the device says it was not a "known command" so I flashed it again with the right script (I had to remove the antirollback section tho)
I'm restoring at the moment. Will tell you if I can add my VISA soon

So it works but Google Pay is saying that my Bank does not support this feature (Welcome to Canada!)
All of this for... NOTHING °*&(?$?&)
Ah ah ah... At least, I know how to properly flash my device. Thx a lot _mysiak_
