I am on new Nougat stock os. Phone has been re-locked.
Can't use the phone for paying and two safety net tests I ran fail both at the last test: cts profile match.
Any idea what should I do to make Android pay work? Thanks
I'm waiting to upgrade to 4.0 until they fix Android pay. I read a couple people say android pay wasnt working but when I asked no one would confirm Android pay was broken...
lock Bootloader needed for safetynet pass on nougat. Put recovery to stock reinstall OOs from stock recovery and relock bootloader.this worked
From what the very little information I can gather, this issue appears to only affect previous users having unlocked bootloaders.
Could it be that there's still some tampering or unlock flag that's not cleared after the re-lock and Google is able to see?

safetynet test apps
For those willing to test safetynet (on an unrooted, locked bootloader ofc) here are some links to test apps I tried:
https://play.google.com/store/apps/details?id=com.scottyab.safetynet.sample&hl=en (rating: 4.6)
https://play.google.com/store/apps/details?id=com.cigital.safetynetplayground&hl=en (rating: 4.3)
https://play.google.com/store/apps/details?id=com.vpals.apps.safetynettestapp&hl=en (rating: 5, out of 8 reviews though)
Magisk works, can't test android pay though cause my card doesn't support it
Yeah, this might be what I'm going to do anyway, it's just a little bit ironic to have to root in order for safetynet to be happy.

I had an unlocked bootloader and Android Pay wasn't working. However, when I locked the bootloader after installing the stock recovery, it is working. I have successfully used it since then.

It's working. However, some are reporting that it's not. It's working for me. Stock with locked BL.
It's finally working here as well. As suggested, I had to unlock again, reinstall stock recovery shipped with 3.2.8 sideload 3.2.8, lock bootloader, several factory resets. I am back on Nougat and safetynet is good now.

I just noticed that I got a security update notice today. I believe it is the monthly one for May security patches.
I recently received a Note 4 from a swappa purchase. I have not rooted and BL unlocked it yet.
If I apply the security update, will it patch the method we are using? I'm not knowledgeable on how to decompile the update file and look at what is in there.
If anyone has already accepted this update and still been able to BL unlock, please let us know.
Thanks

I hear ya. I'm the same way. Well I know for sure that it's fine with the one you have currently installed, so I'd probably just not apply the recent update to be safe and go ahead and convert it to DevEd if that's what you're planning on doing.
Sent from my SM-N910V using XDA-Developers mobile app
I wouldn't take any OTA updates, no matter how much it nags. Get yourself on a supported ROM and check with its developer to see if OTAs are shut off or if there's a way to kill the nags.
Agreed, don't take any ota's...just unlock your bl and get permanent root..the note 5 stock ports are also really nice once you're unlocked.
Ok. I got my phone rooted, bl unlocked, and will install the Paul Pizz ROM later today.
It's great to have a phone with the features I need and the freedom to get updates when Samsung abandons this phone in the near future.

I've installed the latest build of Lineage OS on my Nextbit and set up Android Pay with my card, however when I go to pay, nothing happens. I've read about this problem on other devices such as the OnePlus 3 but wasn't sure if others were having this issue on their Nextbit. Is there any solution?
Phone passes SafetyNet fine and the bootloader is locked.

The reason behind this is that lineageos is not a Google approved ROM. You can usually only use Android pay on stock factory ROMs, without root.

This is false. You might be thinking of SafetyNet, which as I said, the phone passes. Otherwise, there is no reason why it shouldn't work, and indeed it has been confirmed that Pay works on Lineage. The app opens fine and I can add cards, it's just that paying doesn't happen.
My theory is that there's something wrong with the NFC drivers, as this is what happened with the OnePlus, but idk.

Excuse me then, on my Robin, and on my Nexus 4 (with custom ROM) it fails to work but I can still do NFC.
you need root and magisk to get android pay to work with lineage. No other way presently. Lineage worked with my Oneplus One with an unlocked bootloader but not with the Robin. I ended up restoring stock Nougat and it still wouldn't pass. Had to restore Marsh mellow, then lock the bootloader and do the ota update to Nougat. Android Pay now works. It's a shame because I'd rather have Lineage but Android pay is a deal breaker.
Hope this helps anyone in this situation.

Did you recently receive a refurbished device? "No RPMB" in effect means your bootloader will automatically re-lock itself on reboot. I believe it has something to do with a replaced main board.

There's a temporary workaround if you're a stock rooted user:
Here's a reddit link regarding a workaround:
https://www.reddit.com/r/nexus5x/comments/5hj0r0/bootloop_after_lg_replaced_mainboard_bootloader/
However, this isn't helpful if you're a regular custom rom user as you'll notice in the details.
As for DRM, I think so. I have been looking for confirmation about DRM being impacted by this "No RPMB" status. I've only seen one other person outright mention this. It's hard to find users who get this issue and even harder to get them to respond on my inquiry on whether they can use DRM apps. What issue are you seeing with Play Movies? Can you open the app? Or are you given an error message of any kind? I'm interested from the troubleshooting perspective so that I can help ID when others have the same issue. Also, can you confirm this affects other multimedia apps with DRM protection? I was thinking that Hulu, Netflix, HBO would be apps that utilize DRM if you have subscriptions.
Sent from my Nexus 5X using Tapatalk
I don't care much about custom OS, at least for now. I can open Play Movies browse feed and library, but it ain't play any video (Couldn't fetch license (error -1)). Unfortunately I don't have subscriptions in these services, but I used local TV streaming app that uses DRM and it showed error 203 (whatever that means). I tried also watch movies from Google's app on YouTube, no luck.

Unlock bootloader, flash newer version of it and newer radio. Reboot bootloader, unlock it again*, flash rest of the stuff.
*In my case OEM unlock toggle doesn't disable itself after bootloader lock itself. It also stays enabled even after factory reset.
To get root simply flash TWRP instead stock recovery and install SU package of your choice. You can also run customs on locked bootloader and use Jolla's multirom if you want, just keep TWRP installed**.
**Honestly I prefer 4core TWRP modded, it might be life saving one day.
If you use Oreo and want to downgrade it to Nougat or Marshmallow just flash system and vendor in TWRP.
NOTE ABOUT RADIO:
Oreo's radio MIGHT not work on every Marshmallow based ROM (example: XOSP, multibooted Stock - they doesn't detected SIM card also baseband is unknown in my case) it work on CM13, not sure about call quality. It work on every Nougat based without issues.

i was able to flash stock rom via fastbook (had to unlock bootloader 3 times, everytime it rebooted, but it worked tho)
only problem, when i install twrp and press reboot phone, it will only boot to twrp! and i have to type in a decription password or something, because i unlocked the bootloader and android should have deleted everything, but didn't cause i would have to reboot for that, but it will only boot in twrp .. so yeah, that's where i got stuck .. any idea?
otherwise i'll resell this thing and maybe get an htc 10 or a nexus 5x with stock mobo
Hi all,
I currently have stock 8.1 installed on my refurbished Nexus 5X with NO RPMB, and would like to install a custom ROM (Pixel2ROM from argraur).
If possible, I prefer NOT to get root. Maybe it helps passing safetynet.
As I understood, I should do following steps:
- Unlock bootloader
- Flash stock ROM. -> Is this step necessary since I already have stock 8.1 installed?
- Flash TWRP
- Reboot directly into TWRP
- Wipe data and cache
- Flash custom ROM
- Flash Magisk or superSU -> Without this step, would TWRP get replaced with stock recovery? Is Magisk or superSU better?
Can you please check if the steps are right, and answer the 3 questions.
Thanks!
EDIT: I tried without flashing the stock ROM nor root. Everything went fine and TWRP remains installed.
Hello I created a thread trying to help with this cases.. If someone with better knowledge see a better option, please say it there to update it..

Without the magisk part its like you are using a normal rom with a normal boot image, just need to dirty flash the new rom..
With the magisk part it would need to make a new patched boot image..
So at least you will need to extract the new boot image of the new rom file, use it on magisk and patch it, after that I dont know... to my method work the first time it was needed a clean installation, but didn't tried it yet because the new update of my rom developer needed to be a clean installation due to many changes on the rom, so i didn't have opportunity to try update normally but when I do I will update my thread with what to do on that case and if it works..
Hello Everyone!
I am sure this has been passed around multiple times, but my searches are getting me no results, and this is driving me crazy.
For the life of me I cannot get SuperSU to install and root! I've included what I've attempted to install via TWRP below..
I also have another question relating to slots...
So when I install Lineage OS on Slot B, Lineage OS installs it's own custom recovery, which forces me to install TWRP on Slot A, I have to boot into bootloader to switch active slot to get back into TWRP, is there a way around that?
Phone: Google Pixel XL from Verizon
ROM: https://forum.xda-developers.com/pixel-xl/development/rom-lineageos-14-1-nightlies-google-t3601893 (Lineage OS 7.1.2)
SuperSU: I've tried v2.79-SR3, and v2.79-SR2, and also the latest beta version available: https://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133
TWRP: 3.1.0 RC2
Steps:
Booted into bootloader, fastboot twrp recovery, installed on slot A
switched into slot B via TWRP, formatted data, installed the latest ROM from list above.
Installed SuperSU (versions above)
Any help would be great!

Do you have an un-updated Verizon Pixel? With the latest versions of Android, the bootloader can't be unlocked on the Verizon version
Seeing as the OP is booting into bootloader and switching slots... I'd say it was already unlocked

You would be taking a big chance if having an unlocked bootloader is important to you. 7.1.1 is from early this year and getting a refurbished phone that out of date is unlikely. Some Verizon users have reported getting the Google version with the oem unlock option available back instead of the locked Verizon version but that would be like winning the lottery --odds aren't good that would happen if you RMA'd your phone. Also, even if you did get a Google version back you would need to enable OEM unlocking immediately before accepting any system updates from Verizon. The first Verizon system update installed while OEM Unlocking is not enabled will permanently disable the option. Someone reported that they locked their bootloader but didn't disable OEM Unlocking and that a Verizon update disabled the option for them--so at this point you might actually need to have your bootloader unlocked before accepting any Verizon updates.

I've never heard of anyone bricking a Pixel XL yet. Completely power down your phone. Let it sit for a minute. Power directly into the bootloader mode by pressing power and volume down at the same time. When the phone vibrates let go of both buttons. Once in bootloader mode you can flash-all.bat the latest factory image from Google's website and you should be fine.
What were you doing exactly that led to the bootloop?
I have conducted a search on this site and on the web and cannot find anything relevant, so apologies if previously posted. Are we able to root this tablet when Oreo is already installed on the device? I have rooted all my previous android devices (HTC One, M8, Samsung Galaxy Tab S) and never had any issues. However when I tried to root this about 6 weeks ago I got into a boot loop that I could not get out of and had to RMA the device. Is rooting possible under Oreo?
I don't have this device but I have other Google devices running oreo that are rooted and would think this one can too. How did you attempt to root it? Also, when you got into the bootloop did you attempt to flash the factory image with fastboot? It's pretty hard not to be able to recover a Google device unless there is some hardware or other failure.

I tried by enabling USB debugging and OEM unlocking. I then flashed TWRP and then tried to flash Lineage through TWRP, and that's where I got into the boot loop. The boot loop had the following statement 'bootloader is unlocked and OS verification is OFF. Device will continue booting in 30s'
The process also seemed to disable USB debugging so I was unable to flash with fast boot. Can't understand what went wrong and though it may be an Oreo issue?
A couple of things. First, you don't need usb debugging enabled for fastboot, just the bootloader unlocked. When you tried to flash lineage were you on Oreo? And did you flash the Oreo beta of lineage or the 7.1.2 Version. If you were on Oreo and flashed the 7. version you would have needed to also flash the bootloader and vendor images from 7.

I did unlock the bootloader, but when I connected my tablet to my PC it would just repeat the 'bootloader is unlocked and OS verification is OFF. Device will continue booting in 30s' message. I was unable to flash anything using fastboot I was on Oreo when I tried to flash Lineage, and it was the beta version I tried to install.
