Yes, being a China / uncertified device I'd say device tree fingerprint is likely uncertified.

I think I used a different print in past w/ MiPad4 to get 'Device is certified', but then I found Mi Pad 4 China in MHPC list so I tried it and it passed!

I recall being pleasantly surprised at the time, but I'm fairly sure it must have been modified somehow as no 'global' stock etc was ever available and AFAIK China stock was always uncertified.

I wondered, and wonder again if MHPC print came from XiaomiEU custom ROM(?)

ro.build.fingerprint=Xiaomi/clover/clover:8.1.0/OPM1.171019.019/V10.1.1.0.ODJCNFI:user/release-keys

ro.build.version.security_patch=2018-10-01

It's interesting that the wayne print is also 8.1.0/OPM1.171019.

Nb. Security patch date needs to be matched:

Not sure if the above will help, but you may wish to compare with print in device tree. PW

It will not work with 2-button navigation, due to default screen orientation for our device is portrait. So use full-screen gestures or button navigation.

Where I can find instructions how to write logs? And what log do You need to demonstrate bug that during Screen record with any APK (native too) it doesn't record internal sound , just silense ...? Flashed month ago there was such bug, now using 18th July build + flamegapps and magisk, it became much smoother and there is now no cyclic reboot as it was month ago. One of the best ROM that I use but want to use it in 2 months for studying (very need ability to record lectures but it doesn't record sound , only if using micro) It would be cool if we would solve this problem )

Play Store is not certified on this build without majisk/root.

However, Play Store is certified on the previous build - 20210718.

Looks like MiPad4 fingerprint works for those who use majisk, but Mi6x fingerprint works for those who wants to get certified Play Store without messing up with majisk modules.

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

[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] kuskro:
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.

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?

No. Perfectly legal.

E.G.in the UK they're usable. For those channels which are also used by radar the router needs to listen on each boot to check clear. But they can be used.

Is anybody running this on a WiFI-only miPad 4? If so, could you please describe your standby battery drain? It appears that LTE miPads don't have any problems, but the WiFI-only version usually has much higher standby battery drain even in deep sleep with WiFI and Bluetooth turned off. The only ROM so far that I've tried that doesn't have this problem is ArrowOS, but it looks like they've stopped updating for Clover. Thanks!

Also, it appears that Gapps are required for this ROM to work correctly. By any chance would microG (fake alternative Google services/framework masquerading as the real thing) work?

Apparently fine in ArrowOS, but uses 'completely different base'.

@pndwal Thanks for those links. I can confirm what @Wizballs says, I always leave mine in airplane mode and turn on WiFI/Bluetooth as needed and turn them off overnight, but with CarbonROM there's still about 0.6% drop per hour, even though battery stat apps show that it spends >99% of the time in deep sleep.

Is it though? As far as I can tell it's just customized LineageOS. I think that they might have a different kernel config though, I suspect that's where this problem/fix lies.

Don't think so... @rcstar6696 contributed to LOS, Carbon and Arrow, so he should know! 😬

I've only given this a cursory glance, but source for this LOS 18.1 ROM includes Clover from OdSazib and pix106, based on cr-8.0 (carbon) from rcstar6696.

https://github.com/xiaomi-sdm660/android_device_xiaomi_clover/tree/lineage-18.1

Wayne there (11) is from OdSazib also.

https://github.com/xiaomi-sdm660/android_device_xiaomi_wayne

Source for ArrowOS seems to lack Clover, so I assume it uses Wayne or other.

Wayne there (arrow-11.0) is from ReallySnow.

AFAIC, 'completely different bases'. PW
