Thanks for the appreciation. I have just tested SMS on my device and it works fine, i can receive SMS messages and send them without problems. Make sure that you have the SMS app of your choice set as default app for SMS and also check if it has the correct permissions to send and receive SMS.


You might have noticed that the Official LineageOS 16.0 for Xperia Z3 Compact has started today and i have created a new XDA-Thread therefore. Note that the new Official builds are signed and you can't flash them over the current unofficial builds.
If you want to migrate but can't format data you can flash this migration zip over your current unofficial LineageOS 16.0 installation and flash the Official signed build. Note that this could cause some unexpected issues and it is recommended to wipe your data before migrating to the signed builds.

If you want to contribute to the development of LineageOS for this platform you can submit patches through the LineageOS gerrit for the device specific repositories now. How to

I will close this thread and migrate to the new thread available here.

Have a nice day everyone!

    Whole LineageOS Team for this amazing ROM
    I hope I haven't forgot anyone :)

    • 4K Video recording doesn't work in stock camera, but works for example in OpenCamera.
    • You tell me.

    Q: Why i can't reboot into the recovery from advanced reboot?
    A: Because you have installed Magisk 19.1 which breaks it. Keep up to date here: https://github.com/topjohnwu/Magisk/issues/1418

    Good evening, i guess it's time to share an Android 10 build.

    It is uploading to: https://sourceforge.net/projects/ephedraceae/files/z3c/testing/

    currently bluetooth doesn't work.
    Huge thanks to @koron393 who updated the camera shim to Q sources that fast.

    I wouldn't recommend to use it yet if you actually use your phone, there could be some bugs but it's a great proof of concept for now :D

    Have fun tasting Android 10 on z3c!
    Good evening everyone!

    So i have been doing this LineageOS 16 for Z3 Compact since the 5th of january and it's already more then the half of a year. I think it's time to say thank you to you all. Working on this device is so much fun (it repressed my Xiaomi Mi 6 in my spare time) and also the communication is working just great through XDA at this point. Thanks that you help with testing, contribute with fixing bugs or just listing them or even donating some money to me. We really have a community here i enjoy to work with :) I have spent too many nights while doing stuff here but i never regretted it or had the feeling it wasn't worth.
    I hope that we can continue this project in future and keep this five years old device alive as long as possible. This also motivates me to get a new screen for my 2nd device. I guess i will go with the one @StarGeneral shared.
    In the near future i will also sharea new twrp compiled within an android-9.0 environment as already mentioned here: https://forum.xda-developers.com/showpost.php?p=79892993&postcount=3
    Right now i am stuck on the decryption but i am pretty optimistic that we can get this work, apart from this it seems to work fine. If anyone wants to look at the minimal tree, here it is: https://github.com/z3c-pie/twrp_device_sony_z3c

    However i can tell that there won't be any updates within the next two weeks because i am going on holidays finally :)

    Have a nice time
    Short update about Android 10/LineageOS 17 for Xperia Z3 Compact: Bluetooth and the camera after a reboot has been fixed. I will go through a checklist tomorrow and see about remaining problems, it seems pretty good already so I guess that I can share another build tomorrow.
    Good night!
    TWRP 3.3.1 for our z3c out of an Android 9.0 environment!

    * Fixed fastboot boot
    * Added bootlogo
    * Dropped TWRP App

    * Fixed encryption when security patch level doesn't match the recovery's
     - [url]https://github.com/z3c-pie/twrp_device_sony_z3c/commit/411862532c247aea2c7b48d52aa596b40305e9ea[/url]

    * Added a script to handle the CPU
     -> increased the battery life significant ([url]https://github.com/z3c-pie/twrp_device_sony_z3c/commit/63f864068ad2f17ae2f1202b4edc311d74e2803d[/url])

    * Fixed time
    * Further Clean up's

    * Switched from Android 6.0 to Android 9.0 environment
    * Completely reworked tree
    * Working decryption

    The latest build is attached to this post.
    Old builds are available here: https://sourceforge.net/projects/ephedraceae/files/z3c/twrp/
    Source is available at: https://github.com/z3c-pie/twrp_device_sony_z3c/tree/android-9.0

    How to install this build:
    • Rename the downloaded twrp image to twrp.img
    • Reboot to fastboot by holding volume up while connecting your device to your computer
    • Open a terminal and move to the directory with TWRP in it
    • Type
      fastboot flash recovery twrp.img
    • Boot into TWRP while the device is powered off press the power and volume down button

    Feel free to ask questions or give feedback about TWRP here .

    Have a nice day!

    Additional information about the recovery on this device:
    First of all we should make the basics clear: On our Z3 Compact we have got a bootloader update which can boot a recovery from powered off state by pressing volume down and the power button. Because we haven't ever had this updated bootloader and not all sony devices received the update, there have been some intelligent people who brought a special init binary which can handle recovery boots during a normal boot. This means when using advanced reboot from the ROM or pressing a volume key while the sony logo appears at boot. https://github.com/LineageOS/android_device_sony_common/commits/lineage-16.0

    To make this work there is this method to extract the ramdisk: https://github.com/LineageOS/androi...eage-16.0/extract_ramdisk/extract_ramdisk.cpp which uses zlib to decompress it. So far so good, zlib can decompress the default compression for recovery ramdisk which is gzip. However LZMA is more effective to reduce the size so we took it's advantage: https://github.com/omnirom/android_...mmit/885b01223a460d3f2500155ea415bdc8573679bc in order to fit recoverys compiled from recent environments (android-9.0 in my case) into our small FOTAKernel partition.

    According to this change the init_sony can't handle the recovery boot anymore because it can't decompress the recovery's ramdisk so nailyk and Diewi (as far as i know) added support to decompress LZMA compressed ramdisk's with this chain: https://github.com/sonyxperiadev/device-sony-common-init/pull/20/commits
    However these commits have never been merged into the LineageOS/android_device_sony_common nor the sonyxperiadev/device-sony-common-init. Since your ROM, CarbonROM, is using a fork of LineageOS/android_device_sony_common is missing these commits the recovery boot fails with a kernel panic, like this: https://del.dog/egawososux.htm

    So you can either use a recovery which doesn't compress the ramdisk with LZMA (for example the one from here: https://forum.xda-developers.com/z3-compact/development/recovery-twrp-3-2-3-0-aries-t3837192 or ask your ROM developer to pick the according commits into the sony_common tree/use my fork of LineageOS's one https://github.com/z3c-pie/android_...mits/fa85dfcc07f42d73f9a1abf1f4c82d8bf0486a93 which would enable you to use recent TWRP builds with a LZMA compressed ramdisk.

    I hope i presented it clearly and in the right way,
    Have a nice day!

    EDIT: Minimized patch for LZMA is available here: https://review.lineageos.org/c/LineageOS/android_device_sony_common/+/252923
