Fingerprint sensor does not work with unlocked bootloader - OnePlus 7T Questions & Answers

Having some issues while trying to root my 7T, I followed the guide here and everything seemed to work perfectly until I tried adding a fingerprint, at which point I was met with this message. It comes up straight away before I can even attempt to press the fingerprint sensor.

I thought maybe I did something wrong and went back to stock, but I still encountered the issue. I then re-locked the bootloader and the fingerprint sensor became fully functional again. I've tried to search for solutions but I can't find other people experiencing this on the 7T.
I've also tried using a different OS, I went with MSM Xtended v12.0 which allows the fingerprint screen to open but it won't actually register any touches at all.
I've seen mention of a fix to the error relating to persist.img on other Oneplus phones but I'm unsure if this would apply to me seeing as the sensor works perfectly with a locked bootloader, basically I'm stuck at this point and would appreciate any advice

I have an unlocked bootloader and have no issues with my sensor. TMobile converted to International.
Revert to stock and try again.

Yeah it seems to be working perfectly for everybody else on this device which is why I'm so confused.
I've gone from MSM Extended back to stock OOS 10.0.8 (HD65BA) and I still get the same error that's in the OP, I've now re-locked the bootloader and it's back to working again

It can be that something in /persist is broken. It happened to several others too but mostly it is a user error. This message pops up if the fingerprint sensor calibration data is missing or broken. You can try this guide to try to fix it (unless you have a persist.img backup which you can use): https://forum.xda-developers.com/on...de-fix-persist-img-loss-finger-print-t4125909
Keep in mind that the MSM tool doesn't touch /persist so using it isn't going to fix the issue if it due to /persist. But first try to unlock your bootloader again and see if this error pops up again. Maybe it fixed itself

It appears to get to the part where it starts to load the OS. In this case try to get into recovery. If you can get into recovery, great! Then just adb sideload the latest ROM from OnePlus.

How to do that without unlocking BL?

Not that I'm aware of, you might want to try a Factory Data Reset first. After doing the appropriate backups first of course.
If that fails, unlock the BL, flash stock. Once you verify it works lock the BL again. You might have to FDR again to get the Play Store to show Certified if clearing data under Apps doesn't work.
I wish I could still trust my Robin, but I have a battery heating issue that nothing seems to fix. Hence my signature showing my former backup phone as my DD.

Hello, I will use the Google translator because I am Brazilian
Today I ended up trying to install a custom rom on my moto g8, but it ended up giving some errors and I ended up blocking my bootloader manually, but now it doesn't start the phone and I can't install any stock rom with the bootloader blocked, all end up showing an error.

This website has instructions to flash stock firmware on Sofia. Everything but the link to download firmware should apply to Rav. https://www.droidwin.com/install-stock-firmware-on-motorola-g8-power-via-fastboot-commands/

A week ago I bricked my Moto g fast by attempting to flash RetUS firmware without unlocking the bootloader first. Even though most of the fastboot commands failed a handful succeeded and that was enough to prevent my phone from booting to anything but bootloader mode.
I downloaded and flashed the official Boost firmware from lolinet and while the flash succeeded my phone was still bricked.
I installed the Lenovo Motorola Rescue and Smart Assistant tool from https://support.lenovo.com/us/en/downloads/ds101291 and used it to download official firmware for my phone but the rescue tool failed at 14%.
I tried a few other things that also didn't help before I ran the LMSA rescue tool again. This time it took several minutes to complete and my phone worked again. I am not sure why it failed at first but happy to have a working phone again.
hello, i'm also brazilian and i have a problem similar to yours, after leaving a custom rom the other day, and reinstalling the stock and blocking the bootloader, my phone called with the message that it was corrupted and it wouldn't start and now i can only access his bootloader and I can't flash anything, not even the stock rom, I don't know how to solve it, but I'm in a situation similar to yours
Hello, I have a problem with my Moto G8 (XT 2045-1). I tried to install a stock rom to fix a bug, however the phone no longer connects in bootloader mode, nor does it unlock the same and I can't even install any stock rom. Can someone help me?

It also doesn't see the firmware version and bandwidth
Never heard of any such issue. Try flashing kdz.
After installing software using LGUP, the phone keeps resetting itself
It works!!! For those in need: I turned on LGUP and selected the "ChipErase" option

But now you have wiped your IMEI and serial number. In all my guides I warn people not to use that option.
Right. I haven't checked it out. There is no IMEI or SN now. Can it be restored somehow?
Such things are not allowed to be discussed here on XDA, as far as I have heard. You'll have to find another site to see if there's a way to do that.
In the future, don't go running around without knowing what you're doing, because you will break things, as you have just now done. Most people should never use Chip Erase, as detailed on many threads here.
Success with adding IMEI. Now there is still SN

Yeah this sounds a lot worse than playing with Windows Regedit.
Cloned hdd copies are a beautiful thing...

Right on cue, just got my phone working again. I saw this method, and flashed EU ROM via orange fox from Spark OS. Phone sadly got bricked. At the time, MiFlash wasn't recognizing my device and all I could do was fastboot.
Lots of YouTube and 3 hours later, finally was able to sideload stock ROM, then MiFlashed to clean everything, then installed SparkOS again. L1 is back.
I'm thinking the L1 certificate got lost due to Magisk?
Nice, I don't think it's a magisk issue, I've installed and still widevive is l1
Cool! I think I'll pass Magisk for now haha. The trauma!
In any case, if ever I do get Magisk again, can I see what ur modules are?
I'm using sparkOS too, still have it
