Hi. All I know is once I MSN Tool from 11 to 10 I got L1 back because I don't realize that the tool relocked my bootloader.... Then from 10 to 11 update and still L1 (bootloader locked)
Soon as I unlock my bootloader on 11 right back to L1. And I'm super crazy about this issue. Anyway, best I can say is I can't seem to have both unlocked bootloader and L1... So it's one or the other. Nothing I've read our tried has worked and it's like a waste of time trying. But, do what you gotta do cause I failed and you may not. Good luck. Thanks

Mi Flash Tool has the option to relock
Search, you can find elsewhere about the tool (it's generic for various Xiaomi phones), hence don't hesitate to read from Pocco or other (sub)forums
PS: I never used Mi Flash. And I didn't upgrade to MIUI 13
But I do have unlocked BL, using MN SHRP custom Recovery and Magisk and LSPosed with various modules
How did you downgrade to 12.5? As far as I know downgrading could produce many errors and if we somehow forcefully bypassed these errors, the phone could be bricked.
Xiaomi 11 Lite 5G NE Miui 13 Update?
I read Miui 13 is out for LISA. Has anyone received the update yet? For EEA its 13.0.1.0.SKOEUXM.

With an unlocked bootloader, or in EDL (with authorization, works on locked too), flashing the Fastboot version of the ROM should be enough.
After all, firmware is overwritten, XBL and ABL are too, partition layout is the same, same anti version, etc. Of course, user data has to go, since you're going backwards it's the safest way.

Have you tried it? I did try flashing the fastboot ROM via MiFlash but it gave me anti rollback error. If I edit the .bat file to remove the anti rollback lines, it gave crc error. Though I've managed to downgrade by flashing official 12.5.14 recovery rom via TWRP. Seems like MIUI 13 is not blocking user to go back to MIUI 12.

are you on oos 12 ( version c61 ) ???? with the version I didn't manage to have l1 either (with c48 that was no problem with root) but with the c61 nothing helped me either, no matter what I tried, it was always l3
just as this menu is there with the c61 without root and with root this menu simply disappears

I'm on stock A12 TMO LE2127 rooted using magisk and unlocked bootloader. An app I use will not run under this state unless I add it to the magisk deny list. I am widevine L1.

Well this app was working but I had accidently uninstalled magisk and it detected unlocked boot loader and banned me for 2 days , it really costs a lot lol and my exams are coming so to be on a safe side and to prep using my phone (which I was avoiding ) I have locked the boot loader now . Using msm tool to go to a11 gives drm L1 , I have a question should I factory reset after going from a11->a13 and also will it keep L1 after reset ?

If using stock roms all the way to A13, which is the best way to go, you should be ok. You should be at L1 then.
Wildvine level is a complete crap shoot when you unlock the bootloader. Other threads are out there where many of us followed the exact same steps and some had L3 and some L1. I have yet to retain L1 once I unlocked the BL and rooted. Usually relocking it will put you back on L1. Some have reported having to relock it and reset the device. YMMV.
Had L1 after msm a11 , but it has now changed to L3 on C.66 . Any solution guys ?

You might try a factory reset. I know others going through updates and such said factory resetting helped solve the problem...

Question Widevine L1 on COS 13 A11

I found that in the COS A11 version, once the Bootloader is unlocked, the status of the Widevine L1 key will change to Fail, and then become Pass again after being locked, which will not happen in the A10 version(BBefore the A11 was released). Is there anyone like me?
update: I went back to A10 via fastboot, Widevine L1 is still fail, the only solution is to lock the Bootloader, OnePlus¥%…&…

Question L1 question

Is it possbile to have L1 when we unlock the bootloader and root it using magisk delta by HuskyDG?
I have seen some people with OP 9/9 Pro saying that they kept L1 after unlocking and rooting but how to do it with OP 11?
I've tried unlocking but as soon as i do i lose L1 had to relock to get L1 back. Now some people also mentioned that if you do it twice like first time unlock bootloder, root etc. then unrooting and relocking bootloader to try again unlokcing and rooting to get L1. I haven't tried unlocking it again cause it just takes so much time installing all the apps back again.
Op11 with unlocked bl have l3 is not like op9p with unlocked bl and l1

But it should be same as Op 9 Pro minus the upgraded cpu and camera chips structure is still the same. Heck both devices have A13+ support so how come?
