Just upload lineage-18.1-20210720-UNOFFICIAL-clover.zip, changelog :
- update fingerprint along with vendor security patch as per discussion.
- minor update kernel to 4.4.275
Very sorry I got distracted and hadn't tested this sooner.

I can confirm that integrated clover fingerprint is not working.

I tried without Magisk root, then with Magisk; SafetyNet check fails in both instances.

On activating Mi Pad 4 China print via MHPC, SafetyNet passes again.

Both prints show identically as Xiaomi/clover/clover:8.1.0/OPM1.171019.019/V10.1.1.0.ODJCNFI:user/release-keys, but seems they must in fact differ... Perhaps there still a Security patch date mismatch? (ro.build.version.security_patch should = 2018-10-01). PW

On Mi Pad 4 wifi only after a format and clean install I was unable to encrypt the tablet (mi splash screen on and off numerous time) Same thing appended with other ROMs (android 11) everything worked on lineage 17.1 or android 10 custom ROMs so I think is a problem of android. Is anybodyelse having this issue? and how you solve it? I really would like my tablet encrypted

The security patch should be already 2018-10-01 as it is in device tree.

Is encrypted supported by the twrp?

I cant connect 5ghz channel too
All updates after 20210315 have from 100-140 channels blocked for 5ghz. It is an important issue because in European countries the routers swap automatic from 36 to 112 channels, so you have to fixed manually the channel used by your router losing the option of letting the router operates freely to catch the best channel everytime.

Does it mean , this fix is done for compatibility with EU laws , but routers work agains EU laws ?

I was still running lineage-18.1-20210315-UNOFFICIAL-clover.zip. I updated to lineage-18.1-20210718-UNOFFICIAL-clover.zip as that one seems to have certified store without external apps, which is what I want. I did wipe cache after update. It works, and it is certified, but the bootloader needs about 4-10 retries every startup before it actually starts booting the tablet. The Mi screen is on for about a minute, then it completely reboots to 'try' again, and after 4-10 times it finally 'works' and then it boots fine and everthing works. As this is before anything is actually running, I suppose I can't grab any logs for that.
I reverted to the march release which works perfectly fine, but is missing some security updates obviously, which is the only reason I would want to update.
Any clue?

New update lineage-18.1-20210807-UNOFFICIAL-clover.zip (not yet tested by me)

Changelog :
- Aug security patch
- Update kernel to 4.4.277
TY

did you get a chance to look at the WiFi channels allowed?
I am NOT entirely sure but quick google suggests in bcmwifi_channels.c in the kernel might be invovled.


Update - I can't see this in your sources.
But I see elsewhere you mention changing cnss-daemon. Could that be involved?

    Have you try latest rom?

    On the telegram Mi Pad 4 Support Group (AOSP) they are discussing the same problem and there you can find links to two recoveries that can handle encryption correctly. One is a modified TWRP (twrp-3.5.2_9-clover-fbe-20210827.img) and the other one is OrangeFox (OrangeFox-clover-fbe-20210827.zip)

    When I installed Android 11, I can't post a video on Instagram, is there a solution?

    Have you try with Sept ROM?
    Send me the log.

    Clean install and all works great on MI PAD 4 (not Plus)... installed GAPPS Pico and all great working flawlessly.

    Then I did however encountered a boot loop after enabling encryption. I saw other folks with same issue.
    Any clues of what this can be?

    Problem is that I cannot get out of it...

    I am using the latest TWRP 3.5.2 and still kinda stuck in boot loop... I did a backup of all partitions before the encryption and did a restore after that... no luck... then I wiped system partition > factory reset > davlik/cache and then installed again the latest 20210920 but I am still stuck at boot loop...

    Any ideas on how to get out of here? I have a backup of all partitions.
    Well I was able to fix the problem myself... was pretty tough!

    Had to install chinese version of MIUI ROM via Fastboot but because Fastboot was always rebooting it could not flash everything.. so Data partitions was not there... then create /data manually via fastboot and then reflashed LOS 18.1.... then restored the backup on /system and /data. Then I had to remove the lockscreen.db file since pin locking was not unlocking... was really painfull...

    All in all, encryption is not working and is a really pain to put back everything working again. I recommend not to put anything sensitive to your tablet as the files can be accessed via TWRP or even accessed via the tablet itself by removing the lockscreen.db file from /data/system... Is really unsafe to use the tablet in this situation.

    LineageOS 18.1, see this link

    Installation instructions :
    - Download the zip(s).
    - Install latest TWRP for clover
    - Perform a backup of your current ROM (optional)
    - Wipe dalvik/cache (upgrade from lineageos 18.1) and wipe system/data if upgrade from other rom.
    - Flash ROM.
    - Flash GApps (NikGApps is recommended) is a must.
    - Optional: Flash latest Magisk for root.

    Everything should work.

    New update for LOS18.1 and PE11 dated on 20210312 (see 1st post for the link) with March security patch.
    14
    New update : see 1st post for the link
    - September security patch.
    - Add support for app signature spoofing (not tested).

    I also upload new kernel 4.4.283 for anyone who want to try it.

    FWIW, I've used MagiskHide Props Config Magisk module to change Xiaomi Mi 6X fingerprint (xiaomi/wayne/wayne:8.1.0/OPM1.171019.011/V9.5.11.0.ODCCNFA:user/release-keys) to Xiaomi Mi Pad 4 China (Xiaomi/clover/clover:8.1.0/OPM1.171019.019/V10.1.1.0.ODJCNFI:user/release-keys) from MHPC repo.

    Either value works fine to pass safetynet along with Universal SafetyNet Fix module. 👍 PW

    Yes...just try it and it pass the safetynet...and build new rom along with some updates in blobs and integrate it with EAS kernel...

    I am waiting update April security patch to release the rom.
