switched from PixelExperience 13 Beta to lineage-19.1-20220928-UNOFFICIAL-clover.zip while waiting for Fingerprint to be fixed in PixelExperience 13 Beta. Everything smooth so far. I got bootloop at first, but turns out I skipped the format data part. It went through after formatting data.

... I'm assuming, but guess you didn't format data per OP? (See post above) 👍

Guess you'll need this due to Disabled Encryption...

Still, it seems a new data wipe / format may be needed for updates for some users... 🤔 Can others confirm? 👍 PW

With a little more usage I found that many of my apps were crashing. But in each case I just uninstalled then reinstalled and the problems went away. Maybe to do with doing a dirty flash. No further problems once they were reinstalled.
[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] Alecotro:
Hi, I own the 8 inch model. I tried the latest version, 20211119 with nikgapps basic and setup wizard addon. The first problem is the google setup wizard not launching. The second problem is with google chrome and stock browser crashing. Up to here is logcat.txt. After a reboot the wifi was disconnected, so I manually connected it, then chrome worked for a bit and I downloaded and installed vanced manager. After trying to log in to google with the in app feature (youtube vanced) it crashed. I tried several times with no success. Up to here is logcat2.txt. Than I tried with chrome and after a search with google it started crashing again. This is logcat3.txt. I don't really know how to use the logcat feature, I hope everything is done well. Thank you!

After trying all the ROMs, the latest lineageOS 19.1 seems to me the best ROM for my pad 4

I'm running Keepass2android on this ROM. After a few days of running I'll find that I come to open the app and the db is no longer open and I need to perform a full reauth. It's not a Keepass2android security setting (they are set to keep the db open while the app is running) instead I suspect the task is getting killed. One of the suggestions I found online (specific to KP2A) was that it's getting killed by Android power management and to change battery usage to unrestricted. I've done that but it's not helped. @sabar_op or anyone else have any suggestions

I've not tried upgrading to L20, I wasn't sure if was at the same stability level (excellent) of L19.1 yet?

Another question.

Sometimes if I connect a USB cable (for data) I get a "wave graphic" on the screen. It looks like a wave moving up the background from the bottom to the top for about 1 second. I think it's signifying an error in making the data connection but I can't find more info on this.

So my kids cracked my screen. I replaced it. Tablet was fine for few hours until I turned on the camera (with it showing 90% charge).

Screen flickered and it hard reset.

Somehow the battery must have spontanously failed (really bizarre). On reboot I was getting weird issues, bootlooping, flickering screen in TWRP (which went away after plugged into USB for 20 mins) and very erratic battery level reporting. Eventually the battery just quit reporting it was charging.

I load tested the battery and it failed at 1/2A (immediately dropped under 3V). I jerry-rigged the battery upto a bench PSU and was able to get the tablet running more reliably.

But still bootlooping ..... note: during the lengthy debugging I did erase all the partitions without thinking; I guess per the following I must have wiped the proprietary xiaomi stuff :-(

sabar_op suggested trying to flash the stock rom using xiaomi flash tool. I did this and amazingly it worked. I can boot into the stock android BUT I now seem to have a locked bootloader.

If I try the Xiaomi unlock tool it connects and tells me it's locked and I need to boot, go into "developer options" -> "mi unlock status".

But when I try to do that it tell me I need to insert a SIM card. I bought it unlocked from AliE.

Also, AFAICR only AT&T wireless supported the LTE on this device (which probably explains why my Google Fi SIM did nothing).

Is there any other way?
[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] GregEden:
@dorkshoei you could try ADB and use the unlock command.

Note there is a typo in this - he means devices not devies, it is a way to confirm your computer is actually talking to the tablet. It lists connected devices.

{2024 Update} Unlock Bootloader Of Any Android With Fastboot Commands

Fastboot and ADB commands allow unlocking your Android bootloader, enabling custom OS and firmware. This guide covers using fastboot and ADB to securely unlock.

rootmygalaxy.net
[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] dorkshoei:
You mean fastboot, not adb.

I already tried "fastboot oem unlock" and it failed.

# ./adb devices
List of devices attached
97e0c420 device

# ./adb reboot bootloader
# ./fastboot oem unlock
FAILED (remote: 'Token Verify Failed, Reboot the device

I had a BAD FEELING that restoring the stock image, at least using the Xiaomi Flash defaults, was a suboptimal idea.
[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] dorkshoei:
My understanding is that for Xiaomi you need an unlock code.

There are a lot of stale and poorly written articles such as this.

I decided to try this on my Xiaomi Mipad 4 as they have basically same hardward (Clover but 7" WiFi

not

the large-screen plus version)

ROM: lineage-19.0-20211119-UNOFFICIAL-clover

GAPPS: NikGapps-omni-arm64-12-20211018-signed

Clean install

Booted okay and after adding login details it's now recovering my apps from google backup. Google discovery that you get by swiping the homescreen from left to right is empty (edit : got it working just by doing a single search from the google-address bar. The discovery page the started working okay)

Left Pull-down menu looks sized for a telephone but I can live with that. however, many of the other menus and popups are only half-width. e.g. the aforementioned Google-Discovery/Google Home pages.

I'll update here once app installations and updates done, and again after a few days.

Hi - brief update. Google location services is the main service which I can see is not behaving crashes. e.g. Google Maps can't find location. If this is because I'm running Mi Pad 4+ rom on Mi Pad 4 then just say and I'll go back in my box.

@crypticc I have a MiPad 4 LTE 8", not a plus. The ROM works. You need to increase the font size in Settings -> Display -> Font size to Large. Also increase Display Size to Large. You can try extra large even. My GPS was slow to work the first time. Install this app and let it test

GPS Test - Apps on Google Play

Get GPS and sensor information all in one place with an accessible format

play.google.com

The version of the MiPad without the LTE chip does not have a GPS. I have Google Maps and maps.me installed and they work. I would suggest you uninstall Google Maps and then re-install.

Plus I only install NikGapps Basic then add apps from the Playstore and do not restore from backup.

Also install gboard, make it the default, add the number row and increase the size in the settings. Another thing to make it more tablet than phone.
[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] crypticc:
Hi Greg

Thanks. I think the issue with location is because for some reason Googlemaps wanted Google Location enabled, and Google Location Accuracy (the Wifi backup) also enabled. IF I disabled the latter then it momentarily worked but on App restart said it needed Google location services permissions.

I installed NikGapps Omni because I couldn't find "Basic". I obtained from here...

"https://sourceforge.net/projects/nikgapps/"

Another ROM (Android 11) admittedly targeted for Mi PAD 4 clover (not plus) doesn't do this and works. In that ROM I can have "Use location" enabled and Google Location Accuracy disabled, and then Google Maps works/finds my location and without giving errors in logcat.

Incidentally, I also noticed that restore from Google Play, whether from backup or just clicking "install" was taking an age. It wasn't WiFi bandwidth issue as a quick test of that showed >400MBit even while Google Play was baulking.

Looking in Logcat it also looked related to Google Location services being spammed 100s of times before accepting an installation of each app.

I'll have another go at this ROM another day as apart from that issue this ROM was to my eyes "smooth". I'll also try what you suggested, but for a day or few I'm trying another. Thanks though.

Actually, these ROM's target all Clover (Mi Pad 4) variants (WiFi, LTE, Plus...) just like official firmware IINM.

Write the lcd density (for screen/display) in build.prop is now not supperted yet and makes seperate rom for plus and non plus version. I can build for non plus (without gps) but I think better to wait until lineageos is officially release it while I want to finalise to build PE 12.

If I plug my MiPad 4 LTE 8" into a USB-PD charger that also supports QC 3 it will charge at 7w - measured via the battery section of Inware. Not super fast but better than a standard charger.
[Xiaomi Mi Pad 4 Plus ROMs, Kernels, Recoveries, & ] pndwal:
What wattage are you getting w/ standard charger? (Can you give QC 3.0 result also at same charge % level?)

Interesting GSM Arena rates Battery Charging as 10W for both standard and Plus models...

FWIW, using Multi port Aukey charger and Ampere app (Nb. I'm still on LOS 18.1) at around 45% charge level I'm getting 960ma max using QC 3.0 compatible port, but 1030ma from standard port. After 10 min charging I get 910ma max using QC 3.0 compatible port, but 970ma from standard port.

I'm getting fairly consistent voltage readings between 3.8v & 3.9v. So I'm getting approx. 4.0w max according to Ampere but no improvement with QC 3.0 for me...

Anyway, seems QC is not implemented in non-Plus models due to hardware limitations.

Edit:

I just installed Inware app to compare:

At 47% charge I'm getting around 3.5w using standard port when readings settle down. Using QC 3.0 compatible port I'm getting more wild fluctuation, between 1w and 3.5w.

I will take a while as mine is fully charged. But I was getting up to 2000mA from a USB- PD charger. - mine is not a plus. Mostly it sat at 1700 - 1800. But now at 98% battery it is back to slow rates.

Interesting... Missed you said PD charger originally... My charger is QC 3.0 compatible as stated.

https://www.xda-developers.com/how-does-fast-charging-work/

PD rev. 3.1 will do staggering 240w over USB C however...
