- Switched to OSS fingerprint HIDL

- Updated firmware and blobs from MIUI Global Stable V11.0.5.0 for polaris

- Fixed APN related issues in May builds and removed CarrierSettings from vendor

- If you use the latest OrangeFox recovery and see errors flashing incremental package, please

* This should help users who experienced mobile data issue on the first two builds of May (e.g. Vodafone PT)

- Tweaked power hint a bit to improve battery life

- If you use the latest OrangeFox recovery and see errors flashing incremental package, please

* run "rm /system" in OrangeFox's terminal (or connect to a computer and run it in adb shell)

* then install the incremental package

* you will NOT lose any data. This is simply deleting a symlink for SAR support.

* run "rm /system" in OrangeFox's terminal (or connect to a computer and run it in adb shell)

* then install the incremental package

* you will NOT lose any data. This is simply deleting a symlink for SAR support.

2020/05/13

**Device Specific Changes:**

- If you use the latest OrangeFox recovery and see errors flashing incremental package, please

* run "rm /system" in OrangeFox's terminal (or connect to a computer and run it in adb shell)

* then install the incremental package

* you will NOT lose any data. This is simply deleting a symlink for SAR support.

- If your partition is not encrypted, your phone may not boot properly after flashing the update. This is because the zram optimizations changes fstab, so the previous fstab patched by the "disable forced encryption patch" you had on your phone is overwritten. Therefore, you need to flash the patch to disable forced encryption again. If you use OrangeFox, you can also flash the full package, because OrangeFox will automatically patch your phone after flashing full package.

2020/01/31 - 1907

* Fixed double tap to wake on Mix 2s with ebbg screens

* Reduced LED blinking frequency under low battery, without interfering with notification LED

Note: PE has been improving their OTA updater recently and some work is still in progress. Clicking "install" in the updater may cause install error for now. You might need to manually flash the incremental package in recovery.

Update: Updater is only supposed to work with encrypted device. If your phone is not encrypted (OrangeFox disables forced encryption by default), you need permissive SELinux to be able to use the updater.

Here is a quick way to change SELinux status if you have root:

abd shell
su
setenforce 0
getenforce

You should then see "Permissive" being printed in the shell.
