3. Format data and wipe everything.

Note: If you are updating from Android 10 and can't boot the new TWRP, please backup your stuffs and format data by using either the old TWRP or fastboot -w. This is required because there are some adjusts in userdata image size to fix FDE encryption.

just tried flashing twrp to my phone (single sim) running aosp 11, and it couldnt get past the splash screen.
also tried fastboot booting the image,and it just hangs on the sony logo.

it could be the kernel im using, ill try a complete wipe and reinstall of this rom and twrp tonight.

EDIT: flashing stock rom to start fixed it. everything works as it should now.

The twrp-3.5.0-0-20210117-maple isn't working well on G8141 model with this ROM. I've using twrp 3.2.1 and I can say that it is more stable. I've seen that after the flashing I cannot reach the TWRP after reboot and I need to reinstalling the TWRP again. With others ROM's the issue not exist.

i was having the same issue, i fixed it by flashing back to stock firmware before flashing twrp and this rom.


now running twrp 3.5.0 and lineageos 18.1 rooted with magisk 21.4 with no issues.

Thank you for your feedback, but the situation is the same with TWRP. :confused: I've used fastboot -w. nothing changed. Then I format data from the new TWRP 3.5 and after reboot I can't go to TWRP again. Some other ideas what I can try? Regards

Start from stock ROM. Use xperifirm to download the latest stock Rom and use newflasher to flash it. Then flash twrp, lineage and magisk.

Thats how I did it.

First of all: Many thanks for spending all the effort to create this ROM for the old Sony XZ Premium!!!

So far I was using Bliss ROM but the new Android security issues made me to wake up and look for something fresher ;-)

I do have a G8141 (German) device. Flashing worked quite well and the system was booting up quickly. (ROM+TWRP 3.5+openGApps nano+Magist 21.4)

So far I detected just one issue yet which I would like to report:
WLAN and mobile connection not stable. I required me 4 reboot attempts to get a more stable connection. WLAN was constantly dropping out and only a reboot at the end made the device to reconnect. Same for cellular connection. After around 4 reboots I have a stable connection now.
I will monitor the behaviour and hopefully it will become stable after all Google Apps are installed etc..
I will let you know.

Finally I am giving up. I am not able to get a stable WLAN or cellular connection. After installing it again and again (format data twice, factory reset etc., starting all over with latest stock FW) am not getting it working properly. After 1-2 hours, WLAN is not able to connect anymore and cellular is detected incl. carrier but dropping off and data connection not possible to establish.

Really strange was the latest/ last Sony FW everything works. With other ROMS I am running into similar problems. Sometimes cellular is not detected, but WLAN works and sometimes both are not working. Last fully working alternative ROM was Bliss from late September 2020. After reading that several of you are successfully using this ROM I start to believe that this is perhaps a problem with my device made for the German market...

Is there an option to hide the "hide keyboard" button at the bottom while typing? I've already used full gesture but it still shows a bar with hide keyboard button at the bottom while typing.

Thanks OP for bringing LOS18 to maple!!

Weird, after installation and enter the SIM pin and connect to the Wi-Fi network, it take me charge directly from the carrier network for data. Sould be better what connection I will choose during the first installation as primary (Wi-Fi or mobile ) and not connecting by default directly to the mobile internet. With others Android 11 ROMs this issue not exits. Some thoughts?
