Tripped knox is forever. There is a fuse that blows on the phone. That said, there are workarounds on rooted phones (you might as well stay rooted). Try looking for edits for the build.prop to restore functionality to Samsung Health and other affected apps. Dr Ketan still makes ROMs I believe and should have something for you.

I don't want to be rude, but your question was answered already. You can't untrip the know counter. It's an actual fuse, that physically becomes blown. This isn't a software setting, but an actual, physical fuse.

It goes back to the days of people using exploits, and in rare cases would damage their phone in the process, but the phone worked enough to relock the bootloader. Then the person would send their phone back and blame it on the manufacturer. So now Samsung decided to put in an actual fuse so that if you decide to unlock it, your warrenty is permanently void.

Bottom line, your out of luck. I know any unlock would have given a warning that it is PERMANENT and that it would VOID YOUR WARRENTY. Wether you read it and ignored the warning, or didn't bother to read it, it's on you for unlocking your bootloader.

Yea I remember those days... Well truth is I haven't rooted.. I was considering it until I read the warranty part... My point is, the reason I want it rooted is because I want to use some modded applications. I researched further and found out I could use some without even rooting. So i tried downloading Spotify mod app, but unfortunately it didn't work. I couldn't get recent application for it, what I kept getting was an outdated mod app. In all it didn't work. So am asking if there's a way to use mod apps without rooting the phone. Thank you

You'll have to wait until someone mods the latest app. Or, you could just pay for Spotify. For the record, I used to use a modded Spotify, and they typically patch within a day or two of a modded apk being released. They may have finally switched to server side authentication which is why your likely not seeing an updated version. I stopped bothering because it's just a cat and mouse game. I didn't feel like Spotify was worth it, so I moved on.

I find Google Play Music is a better deal. I get add-free YouTube, and all the same music as Spotify, for the same price.

On a side note, I don't believe Xda allows modded apks that bypass paid features. There are sites that cater to such things, but I'm pretty sure it's a no-no here. They tend to support devs / companies as opposed to cheating them out of money.

Hi, you can flash the U1 firmware on the Sprint 965U. You need to use the patched Odin linked in the OP. The CSC file included is for multiple carriers. When flashing it will read your sim and setup accordingly.

The thread provides detailed instructions and the most current firmware. The instructions are new to the thread and so are the links. Didn't realize I was required to explain what was new to you.

I don't use the "B" revision firmwares, but there was at least one listed as a BOYD firmware. Since your already on U1 and loosing wifi-calling, HD voice, volte, etc, that might give you the best luck. Might be something to look into.

You asked about sim swapping for traveling. The BYOD firmware makes for easier sim swapping. It's designed to populate the carrier settings when you insert a sim instead of needing to wipe your device.

As for ATT features, I believe those firmware are for the U firmware, so yes, you'd regain those features, but you'd get the ATT bloat. I don't mind the bloat personally. I just remove the junk I don't need.

    If you already have it, why not upload it to G Drive and save a lot of time?
    It's also available via the samfirm tool. Downloaded it in about 5 minutes.
