Greetings. After trying Derpfest on my Redmi Note 7 Pro, I decided to switch back to MiUI. I wiped out the entire Custom ROM, then installed Indian version firmware, and then installed the latest MiUI ROM in recovery mode (I prefer Orange Fox). After that, I wanted to relock my bootloader so I got the latest MiUI 11 fastboot ROM and then used MiFlash and used the clean_all_and_lock option. My device relocked it's bootloader, however, it turned out that several things like sensors or Find Device service were not working correctly. It also showed a message "Find device storage corrupted, your device is now unsafe". Looking for solutions, I ended up unlocking the bootloader again, getting back OFox, and installing the persist.img file which I extracted from my fastboot ROM. This fixed the issue with the sensors. But now, I still can't get access to services like Find Device (both from Xiaomi and Google). If I have to avoid the 'Find Device Storage corrupted' error, I have to unlock bootloader. If I have to lock bootloader, I get the error message. What am I supposed to do?
I also have tried older Fastboot ROMs, although they were all MiUI 11. Should I try fastbooting into a MiUI 10 ROM and then get OTA to do everything else? If this is the case, which specific version of MiUI 10 ROM should I flash? I can't remember which version my phone came with. My model number M1901F7S. And also, I've never used Magisk. I didn't really care if I wanted to root or not. Derpfest passed Safetynet pretty nicely. But now I do not wish to root. I don't want Magisk or anything else, I want to secure the phone just as it was before.
EDIT : Turns out that Find Device (from both Google and Xiaomi) are actually working, just in a less effective scale than what I previously used to have (before getting the custom ROM). But yet, can I bring my phone back to the locked bootloader state? I want to secure it completely, just like how it was when it came out of the box. I also cannot install apps like Netflix. I would really like to know how to relock my bootloader.
EDIT 2: I've fixed it. Indeed, I had to flash a stock MiUI 10 ROM. Version 10.0.2 and whatever number ahead worked for me and gave me no problems, and then I simply updated to MiUI 11 using OTA Updates.
However, I do not recommend using MiFlash tool, and instead recommend pasting the ROM files into your platform_tools folder and then running flash_all_lock/flash_all. MiFlash may sometimes glitch and cause problems.
