100% unmodified unboxed 6 days ago. No Root, bootloader not unlocked (OEM unlocked but "relocked" it as it was pointless) I installed Root Browser just to check and I think I have access to files I shouldn't have access to without root. Images of the "home directory?" below.

Is there any way to relock the bootloader on exynos s9+? Ive tried reflashing stock via Odin but the bootloader is still unlocked and not allowing me to use android pay etc.
I know knox will be tripped but there's no reason that I can't use android pay with a non rooted phone surely? I've tried the root checker app as well and that shows that I do not have root.
When I check in developer options it says the bootloader is already unlocked and the slider is to the left for the oem unlock option. I have tried to slide it to the right which factory resets the device but then on going into developer options again it still shows as the same status (bootloader already unlocked with oem unlock slider to the left)
What can I do to get my phone properly back to stock?
Thanks

Actually there is a good reason why google pay wouldn't work even if the device isn't rooted. There are Payment/banking (and other apps I am sure) require that the device be secure. With the bootloader unlocked the security on your device is severely weakened.
Did you root the phone at all, flash anything to the phone or do anything to modify it at all (something like this as an example). If there was nothing at all done to the phone other then toggling the oem unlock, then it sounds like flashing the proper firmware to the phone, unticking the oem unlock option and factory resetting the phone should work.
If knox is tripped then there is no reversing that. Google searching also shows this would be a likely cause as to why you can not relock the bootloader.. Once knox is tripped it is irreversible (this is because it is an E-fuse), not even flashing stock will not make it go away.
I think your best bet at this point might actually be to have root and then use Magisk to hide root from the apps you want to use. I'm not sure which apps this will work for but it's probably worth looking into since there may be no going back with your bootloader
Thank you for the help guys. I did suspect that may be the case and I wouldnt be able to relock but it seemed some people were able to.
Will just root with magisk and use magisk hide to make it work. Thanks!
Hi,
My phone is running official stock firmware, however the bootloader remains unlocked, as such apps protected by the SafetyNet do not work.
I've seen guides saying that you can simply run some code via adb, but I'm guessing this won't work in this case..?
Unfortunately I do not have a backup of the TA partition- does this make re-locking the bootloader impossible?
If so, are there alternatives for patching the safetyNet that would work?
Many thanks
Hi -- we have a LG V30 (US998) that we were told was rooted. On boot up we get the message Your device software cannot be checked for corruption. Lock the bootloader. see g.co/ABH. I read on XDA that means that the phone has only had the bootloader unlocked but it hasn't been rooted. When i used root checker basic it says Sorry! Root access is not properly installed on this device. -- so there is no root access to the phone.
Two questions: Can we get back to the OEM install if we lock the bootloader or by other means? The previous owner says we can't go back but it is obvious that we have an incomplete or unsuccessful attempt at rooting. If we can't go back what is the simplest and most direct root to continue with the rooting? I can follow clear and precise directions -- I did root an old Note 1 but did not follow up as the phone is so old.
thanks in advance

Yes. You have Bootloader Unlocked V30. They've done most of the hard work for you. By the way, that Bootloader Unlock warning is the badge of freedom. LG tries to make it sound scary. Just ignore it.
Even though you're not rooted, I'm curious if you already have TWRP custom recovery installed? That would really cut down your to-do list!
IF you don't have TWRP custom recovery installed, then you just need to follow Section 6 of the WTF instructions. You're Bootloader is already unlocked. You just need to install TWRP, + three root files, including Magisk and reformat your internal memory.
Exactly what firmware version are you on in About Phone? If you're on something like 20a or 20b, after the paragraph above you would want to update to newer firmware. Or you may already be on newer firmware?
See post #192 of this thread:
https://forum.xda-developers.com/lg-v30/how-to/wtf-lg-v30-t3790500
Or click the huge hyperlink in post #1...
You want to follow the directions in Section 6, but you'll have to read some of the prior sections to download the files you need (ADB, etc.)
I've done a good bit of scouring here but cannot seem to get a definitive reason or fix to my current issue.
Here's the order of events:
Bought a new N200 unlocked version.
Unlocked bootloader - no issues.
Put TWRP on it - still a WIP so the issues with it were expected. It's minimal and is not fully working. I was aware of this and succeeded at this step as well.
Put Magisk on it. Once again, minimal issues.
Decided to return to stock because it's difficult to update the device.
Removed root. Complete uninstall of magisk.
Used payload dumper to extract the factory boot image. Used the same method to reinstall this to the device.
Booted back to stock recovery. Completely wiped device keeping system intact. Then booted up.
Booted back to fastboot to relock bootloader. ERROR - DEVICE CORRUPT.
Hardware booted back to fastboot and unlocked bootloader. Device works.
New partial update rolls out. Cannot update.
So here's the issue. I cannot relock the bootloader or the device will read as corrupt and not boot up. I also cannot update the device because it states the device is either "busy" or has an "installation problem". I also cannot sideload from recovery because it states the device is unauthorized (weird since the bootloader is still unlocked) and sideload doesn't really seem to work via fastboot either.
Any tips or help that can get me completely back to stock on this unlocked variant would be greatly appreciated.
You'll have to just redo everything msm your device back to factory. Then update to the partial patch. Afterwards you can do the root process.

The problem lies in the MSM part of your reply Winnower. I have the unlocked variant. The tool for that is not available. Not yet, anyways. But I am hopeful I will be getting my hands on that today for the community.
You could use Android studio to piggy back on the update file.
When you relock the bootloader, you have to have correct vbmetas. (Verified boot metadata). When you unlocked, OnePlus automatically disabled them. They may have been cleared (This is the usual way to disable verified boot, by blanking the hashes from the vbmetas.) or they may just not match the current version installed.
You restored to the "full" OTA version from the website, but if you previously took a "patch" OTA update over the network, your existing vbmetas would not match the full OTA version.
Also, keep in mind there are two slots to deal with. The sideload update mechanism checks both copies for modification, and you probably only reverted one.
I've read comments by others that relocking the bootloader is not a requirement for the sideloader to update, but reverting the software is.
I have tried for multiple hours to get fastboot and ADB to work with my S6 Edge but it is not working. I suspect I might need to try older Samsung drivers (I only tried the latest ones as far as I remember). I wanted these tools in order to check if my bootloader was unlocked so that I wouldn't brick my device if I tried to install a custom ROM and TWRP. Anyway I followed a video and installed TWRP on my phone and installed Lineage OS Android 10 without checking the bootloader since the guy in the video did not mention doing so and still installed the custom ROM and TWRP. It is working fine. I know it is most likely that since this was possible, the bootloader should probably be unlocked but I just wanted to confirm with more experienced smartphone modders if this is indeed the case. Is it then safe to root my phone without checking bootloader?
Sub-question: If a person were to theoretically attmept to install custom ROM or TWRP or root the phone while the bootloader is locked, would that result in the root failing but the device still being usable or would the attempt result in the device being bricked? IE if the bootloader is locked is it dangerous to attempt to flash software to the phone or will it result in a harmless "failed" message, etc.?
Thank you.
