INSTALLATION

Put the zip file of the ROM on your sdcard or internal storage, boot into recovery and flash. When coming from stock: boot into TWRP, format data, reboot to recovery and wipe all internal partitions. Then flash the ROM, GApps (if needed) and root (if needed).

Note: There is not going to be a LOS su addon anymore. If you need root, flash a root manager of your choice. No guaranteed support from LOS for this.

When updating from builds, simply dirty flash the ROM.

If coming from 17.1, please see advice below in second post ("UPGRADE LINEAGEOS").

KNOWN ISSUES

• WFD is not working yet (waiting for new non-BSP blobs)
• Stock camera is not working anymore due to incompatibility of stock library (libimageprocessorjni.so) with new libgui
• You tell me...

SECURITY ADVICE

Don't flash ROMs or Magisk modules which set SELinux to permissive or you welcome malware on your device!


UPGRADE LINEAGEOS

I have not tried upgrading the device from 17.1 and cannot guarantee that it will work - you should do a backup just in case. If things go wrong, flash it as if coming from stock (see instructions in OP).

The following steps should work though:

• Flash new twrp and boot into it
• Flash new rom, opengapps and any updated root solution you use
• Optional: Clear cache
• Reboot

Note: When updating form Lineage 17.1, you maybe have to once change your preferred network type from 3g back to 4g/LTE.

UPGRADE FIRMWARE

• Grab the Sony Stock firmware using e.g. XPeriFrim. You should always flash the firmware matching the LOS build.
• Grab newflasher and put it in the same folder as the firmware files.
• Read the newflasher original post on XDA for general instructions!
• Remove the following from the folder so they won't get flashed:
  • all *.ta files (keep the one in the boot/ directory)
  • cache*.sin
  • fotakernel*.sin
  • kernel*.sin
  • system*.sin
  • userdata*.sin
  • vendor*.sin
• Turn off your phone
• Hold the volume down button and attach it via USB to your system till you see LED turning green
• Run newflasher from within this directory to flash the remaining files
  You can say yes to the first optional step, in case you don't have working drivers installed.
  Skip the second optional step (dumping of trim area), it's useless if your bootloader is unlocked already and takes a long time.

How to get root?

As mentioned before, there will not be an official su addon from LOS anymore. If you need root, flash an unofficial solution.

Google Apps

You can download and install the Google Apps from opengapps.org. You need ARM64 and 11.x. I suggest to *always* use the pico or nano package. If you need additional apps you find them in the Play Store.

Open GApps for Android 11 is still in beta. You can download those releases here

MicroG

This ROM doesn't support Signature Spoofing. However we are watching MicroG and check if they provide newer builds e.g. for Android 11.

Thanks @derf elot ! For all your and the rest of the Dev team's efforts.

What can we (the community) do to help get the camera back up and running?

 

[JimKatsanos]

Ok THIS WAS THE BEST BIRTHDAY PRESENT EVER... I'll test it asap

Unfortunately, I am not sure there is much that we can do. The stock library that we need for the stock camera app to work properly (libimageprocessorjni.so) is not liking the new Android 11 libgui. We (also with the help of @j4nn ) tried to fix these issues in various ways, including shimming and forcing the use of the 10 libgui but haven't managed to get it working properly yet. Maybe we'll have a crack at it again at some point, but I wouldnt get my hopes up too much. It also doesn't help that the XZ2/3 series is not getting an official Android 11 update. Opencamera is a decent alternative, although it does lack some of the stock camera options.

Ok THIS WAS THE BEST BIRTHDAY PRESENT EVER... I'll test it asap

Happy birthday. I hope you enjoy

Oh nice, and I just got the device today (new and unopened) but for some reason I can't flash it to a different or use even the official tool from Xperia to "repair" my software.
First thing I'll do after upgrading will be checking this rom.
Thank you a lot!

It's just working fine here with opengapps beta. Mostly likely nikgapps broke dialer app.

I also tried Nikgaaps (full version from 12/30/2020) and I don't have this issue. Maybe you used a different version or build.

I have added support for both of these internally, so a custom OEM should not be needed anymore. I know at least of one person where it's working on maple. is it not working for you?

I'm sorry. I just found this option in Settings. It seems to work.
Thank you again for your reply.
By the way，are there any plans to add volte video calling?（This is not a requirement.）
