Looks like an encryption issue to me. If you came from a previous TWRP based on an earlier kernel (probably 4.4) then you need to do the following:

Flash the latest TWRP

Reboot into recovery and format data

Reboot into recovery again

Flash ROM & any additional required zips

Format data again and reboot system

As you can't get into TWRP currently I'd try all of those steps.

I now have the latest version of Lineage 20, the only latest recovery that works is twrp-4.19-3.6.2_9. If I install TWRP, which is recommended in the topic header, via fastboot, it simply does not work.
[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] CityKev:
I have the TWRP recommended in the header but I don't have this ROM installed so maybe there is an incompatibility issue somehow. I am on the latest Arrow ROM by the developer who built the recommended TWRP.

First--thank you for extending the life of my tablet with this build.

Now to my issue:

On my Xiaomi MiPad 4 with this build of Lineage OS 20, Google Maps and Chat use a vertical split layout that feels broken. See this screenshot for an example of this in Google Maps:

View attachment 6039982

Notice that buttons on the left pane are abruptly cut off and the right pane is tiny. This makes Maps a pain to use. Whereas on my Pixel 5a with official Android 14, Maps uses a horizontal split layout with plenty of space for the map pane. Similarly for Google Chat: on the tablet, the list of chats takes up half of the vertical split, leaving the actual chat bubbles cramped into the other half.

Any idea why these apps are doing this on the tablet and what a possible workaround could be?
[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] GregEden:
Try reducing screen size in settings. You might have to give up the traditional buttons and go with gestures.

I have moved to Lineage OS 21 and my maps app is split horizontally, not vertically like yours. I cannot remember how it was in Android 13.
[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] priorityinverted:
Aha! Increasing the display size fixed this. Thanks.

I have been using miui 10 for years. I decided to install this room because it seemed stable and neat. And it is. It works very well. I had some problems flashing (the typical error "failed to mount data"), but I solved it by formatting the internal storage. I didn't have much to lose because it's a 300€ tablet from almost 6 years ago. Very happy to be able to give it a second life: it works better than with the original software.

No matter how many times I flash TWRP 4.19, it still displays that my recovery is 3.7.0_9-7

I tried already as the following:

- Version 3.7.0_9-7 of the current recovery to flash 4.19

- The latest platform-tools (ADB)

- XiaoMiTool V2

But no hope. Any solution, please?
[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] GregEden:
4.19 refers to the kernel version, not the TWRP version. You need a 4.19 kernel version to run Android 13 and 14.

The latest version of TWRP for MiPad 4 built to support kernel 4.19 is :-

twrp-3.7.0_12-2-clover-20231126-0838.img

The version you have is new enough, but you might as well go for the newest.

Also the Android 14 ROM is fully functional and stable. The main thing you lose is Play Store Certification due to Google tightening the requirements with Android 14. I just installed Netflix from APK and it updates after that.

Thank you so much. You made my day. I flashed Lineage 20 (Android 13) successfully. And it looks great when compared with the original one.

Just one thing I think it's a bit annoying that Google Play services keeps stopping almost every minute. How can I deal with it, please?
[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] GregEden:
Clear playstore data and reboot. Next to try make sure you have the latest GAPPS. If necessary flash the newest NikGapps over what you have

I did clear Play Store data and reboot twice. But it keeps stopping.

[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] GregEden:
One last thing. Sabar stopped work on this ROM when the first Android 14 ROMs were built. So it is frozen with no more security updates. You might be happy with it as it is, if so keep using it. There is an argument for stable rather than updating monthly.

The 14 builds are stable now and mine works well. But you also lose Playstore Certification. That does not matter for most applications and is a matter for you.

ADB RSA Authorisation issues >> Fastboot - Linux (Windows Powershell Admin works despite no keys on tablet so that's the 'solution') LineageOS issue?

Unsure if its just my MP4, but the only way i can get fastboot via linux (it times out after a second or so and reboots) is via Windows 10. There is no authorisation prompt on the tablet. Indeed there ought to be a Revoke USB Debugging Authorisations option directly underneath USB Debugging option, but its missing completely. Although a settings search imagines it should be there. I dug down as I was curious. The only thing haven't tried is manually generating my own adb_key on the tablet.

Strangely adb devices recognises the tablet. But when bootloader comes up it immediately crashes out.

On the MP4 the /data/misc/adb dir had not been populated. It was empty. btw I think its a general LineageOS thing with these more recent builds: I also had this experience with CRDroid A14 and Sabar_op LOS21. My laptop/linux more robust obviously than raspberry pi, as fastboot attempts overwhelmed the RPi totally.

My A14 phone doesn't have any issues and the ADB RSA authorisation prompt comes up if necessary.

Just FYI in case others run into it, and also to inform developer in case of interest. As noted Windows Powershell has no issues.

When TWRP asks for the password to decrypt just press Cancel. Unless you have deliberately encrypted it, it is not encrypted.

A few observations on my experience with the current build for those sitting on the fence. I have a MiPad 4 8" LTE

Wifi works fine. 4G data works fine. Rotation works on the main screen (I have not tried the lock screen). The Playstore is not certified. The GPS works as expected and after the first use locks on quickly. I have Sony Bluetooth headphones and they connect via aptX HD and play music nicely. I have one media streaming app that will not rotate and I expect Netflix will be the same. I use an app called Orientation Control to lock it in landscape when I need it. I pay for Google 1 VPN and it works as it should. I use various external USB-C drives and they all work as they should and I can read and write data. I have a 256GB microSD card and it seems to function at full speed. I have not tried the microphone. With the last 12.1 builds I could use the recorder but not do Duolingo lessons. Something to try when I have time. I do not use Magisk.

The official TWRP is based on 4.4 kernel, it will work in 4.19 kernel rom if the rom has same encryption type with the TWRP.

[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] Argaricolm:
Yes 3.6.2 was installed. Now installed latest version 3.7. And still it did not started to system.

Only Data wipe allowed to start system. But ofcourse all data lost.

Switched to 03.10 version. Maybe the problem is because of 10.10 version (because it does not work fine with GApps).
[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] GregEden:
I installed 10.10 and it was not functional, so I wiped it and installed 03.10 and got it running, then dirty flashed 10.10 and it is working OK. That strategy was suggested by @Argaricolm

The camera is still an issue.
[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] GregEden:
I also set up my tablet to feed music from my Tidal account to a DAC using LDAC. HiRes audio from Tidal shows as HiRes Audio on the DAC display so the MiPad is sending the good stuff via LDAC Bluetooth codec. Sounds very good. My MiPad is now a handheld jukebox driving my HiFi and doing it well.

[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] zyhk:
I wrote above based on LineageOS 19.1 at that time. Now I've just updated my pad4 to LineageOS 20.0, and found that this latter ROM inverted the meaning of the DRC switch ("speaker_drc_enabled" in "/vendor/etc/audio_policy_configuration.xml") unlike the former one. A bug or a tweak? (why not turn off the switch?)

Under the default state all audio outputs are now without DRC, but are unusually with DRC when DRC remover is used.

Edit:

You can easily check the audio outputs with/without DRC by switching "on/off" on the fly if you use my root script USB SampleRate Changer (for not only USB DAC's, but also a 3.5mm jack, an internal speaker and Bluetooth earphones).

[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] GregEden:
I have switched over to LineageOS from sabar's Pixel Experience. This is a cut and paste with small variations from what I tested on Pixel Experience. They are now effectively equal for me.

I did a clean install and did not restore anything. I then spent an hour in Playstore adding back all my most used apps and logging into accounts. So an absolutely clean install. I also used Fastboot to install twrp-4.19-3.7.0_9-clover-20221007-0724 before installing this ROM. I do not use Magisk.

Autorotate works in all my apps, and on the lock screen if you enable it in settings. Playstore is certified. Netflix is installable and indeed runs fine. Netflix is in SD as is always the case but on an 8" screen SD looks good.

WiFi runs at the full speed of my Internet connection, so close to 100Mbps. My connection is via a 5Ghz channel. 4G LTE runs at about 50Mbps which is only limited by my reception. Bluetooth works and my Creative headphones default to aptX HD. I have a Bluetooth DAC for my HiFi and it connects via LDAC for the best bluetooth connection you can have. My wired headphone and microphone work as well.

Microphone works and I can run Duolingo without problems (something that I have not been able to do for a while).

I use external USB-C drives. They work. They also work via the Google Files app, which was not always the case. I have a 256GB microSD card inserted and set as external storage. It works fine.

GPS locks on quickly. No issues. Compass apps and SkyMap work as they should. Google Maps and maps.me work as they should.

I have a Google One account and the Google VPN is installed and running. I also have Avira anti malware installed - the free version.

I use Google Authenticator and was able to use the camera to read the QR codes from inside the app. Google Lens works and will capture an image and look for results.

All in all a very polished product. I do not see much that needs fixing. For me the camera is only for using as a QR scanner, Google Translate and Google Lens and it will never get used for actual photography. But it works.

Inware reports that root is hidden. Thus I do not see any problem with using banking apps if you wanted to do that.
