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

Hi, I can't open your thread in XDA Labs app, I suppose that's the case of many people and that's why there is not much views and comments on this thread.
I didn't tried yet your ROM but it sound great and will try it ASAP.
Also which recovery do you recommend to avoid errors like error 7 (if I remember) ?
Also will you continue to work on RR ?

EDIT : after posting this comment via browser, I can now open this thread in XDA Labs

EDIT 2 : everything is working

I use twrp-3.2.3 from here: https://forum.xda-developers.com/z3-compact/development/recovery-twrp-3-2-3-0-aries-t3837192.
I don't know yet about RR. I wanna see first whether we can get Bluetooth and gps working as soon as possible.

To be honestly I can't follow you. Do you mean that you don't know how to update the build? For this case you have to download manually and flash it in TWRP. There are no wipes needed.

Murtie · Jan 11, 2019 at 10:54 PM

Hi, thanks for this and how is the battery performance?

Any plans for making an LineageOS for microG rom?

dobosvok · Jan 2, 2011 5 2 0

Thanks for the ROM, I am using it right now, everything is working good except the camera. Can take photos, but video is not working. When I'm switching to video, the app is freezing and stuck. I tried to use the stock camera with magisk, it can't take photos or video neither. Tried manual camera too, it can take photos but no video.

I have the ROM installed on TWRP easily.

WLAN and mobile data are stable.

Unfortunately, GPS with navigation app does not work.

Also Bluetooth with the car handsfree does not work properly. You have to connect manually every time.

I am looking forward to testing the further updates.

Please continue. Many Thanks.
