Extra Features
PixelExperience feature

Whats working?
Almost everything

Known issues
DON'T FLASH GAPPS, THEY'RE ALREADY INCLUDED
--

ATTENTION: How to flash
* For full steps please check the PixelExperience wiki

Since pixel experience is packed with pixel gapps, the system partition can't hold that large originally.
So I switched to retrofit dynamic partition(aka super.img) and fastbootd(userspace fastboot).
It's logical and won't affect the real partition table which means you can still go mi flash for fastboot or 9008 to flash the system/vendor partiton for un-brick.
However this method DOES NOT support twrp.

To install/OTA update this ROM, you MUST use the pe recovery which is provided with the ROM.(For official, it is also a MUST for publishing, OTA update won't need flash again after/before rom flash, just need you keep the recovery)

For flashing recovery, use following command on your PC
fastboot flash recovery <img name>

Boot to recovery
Tap "Factory reset -> format data"（This will delete all your data! Only need for first time switch to PixelExperience）
Then tap Apply Update -> Apply from adb
Start sideload by following command on the PC
adb sideload <zip.name>

# Or you can just put ROM on a fat32/exfat/ntfs sdcard/usb otg and insert/plug it, then you can choose it in pe recovery like twrp.

If you see any "metadata" related error, just ignore it, it's common on the first dynamic partition flashing, and won't appear next time

To switch to other ROMs, format data in PE recovery first, and then install another recovery then the ROM.
Eg.
1. reboot to pe recovery -> Factory reset -> format data
2. Back to recovery home -> Advanced -> reboot to bootloader
3. flash another recovery such as twrp
4. press vol+ and power to boot recovery
5. do another factory reset (and a format data if it is twrp)
6. install(/sideload) another ROM's OTA zip like MIUI stock or LineageOS etc.(Warning: the ROM to install must have same kernel version with recovery. Eg. you can't use twrp-4.19 to format then install stock MIUI)

FAQ:
1. How to enable/disable the task bar below?
Long press the space in taskbar or gesture indicator(the white bar)

2. Why 90/85/75/60 still laggy or feel like 30hz?
Google need warms up, so after you booted like for 5mins, it will be smooth on that refresh rate.
And for OFFICIAL version, I can't provide any overclock, so the full ROM package will be only provided with 60hz.

3. Why twrp get's error/Must use PE recovery?
Check the "ATTENTION" on #1.

4. What is 13 / 13 (Plus edition)?
The 13 (Plus Edition) NOT means it's for pad 4+, It's PE+, the 13、13 (Plus edition) both available for Mi Pad 4/4+. PixelExperience Plus will have more custom features.
Also, if you are already on normal edition, you can directly dirty flash the same date plus edition or newer plus edition.

5. How to solve heating/power drain too fast on idle?
Usually this won't happen when you clean flash this ROM, and often caused by LTE driver and a system application updated by the Google Play Store called: Android System Intelligence
So, just try enable airplane mode and uninstall the update for that app then reboot will solve (Settings - Application - Find "Android System Intelligence" and click top-right corner button)

6. How to flash certain partition with pe recovery? (like boot, frp, recovery, persist)
Use
fastboot flash partition_name partition_name.img
OR

In pe recovery:
Advanced - enable adb
Then On PC:
adb push partition_name.img /tmp

adb shell

dd if=/tmp/partition_name.img of=/dev/block/by-name/partition_name

Saw your patch on Gerrit for fixing launcher on tablets, I didn't realize that you have a clover!

 

[Piccolo1]

perfect rom installed. I wanted to ask if you could build on kernel 4.19 and include the xiaomi parts to have screen color management and volume enhancement

( kernel 4.4 is no longer supported eol )

Thank you for a great rom.

I installed version 2023-02-18 and during various tests, I noticed an issue with microphone sound not being input.

The test app used Google recorder, and it was able to record the bluetooth microphone, but not the mipad4 device microphone.

Thank you very much for the great work.
Very fluid and so far working perfectly.
It only lacks the play protect certification. Uncertified device.
I hope to give my Mi pad 4 tablet a long life with this ROM.
