I'm having problems with this rom now. I updated to latest version but nothing changed. When I boot the phone all is working, but few minutes next the sim card icon shows "no sim", and calling is not possible. Restarting the phone, the sim card is working again for a few minutes, and dissapear again. And always the same.
What is the problem, and have any fix?

Phone didn't even get Android 9 or 10 so no, no 11 for it. It's a 6-year-old phone now, so it's just time to move on. Or you can still use it for very basic tasks.

Do you have any plan for building LOS 17.1?
There is a plan, but there is not enough time. And I know that everything will be greatly slow down.
Optimal here is LineageOS 14.1

Go-mode I do not like, there are a lot of software is no longer working (background players, autonavigator and road cameras notification).
In normal mode, they all work fine, although of course the phone slows down very much at startup and at exit.

Phone didn't even get Android 9 or 10 so no, no 11 for it.
Android 9 exists, but there are some problems so it is not published.
Android 10, in principle, can also build, neighbors on a similar processor and a similar platform have it for a long time.

I want to make a different kernel, but so far the result is bad…

Let me ask again only to understand you correct : you are the Developer of this LineageOS 15.1 ROM and despite that fact, you personally think that LineageOS 14.1 suits better for this device because Android 7.1.2 would perform better on that old Hardware?
:confused:

The google documentation, Minimum Memory and Storage (Section 7.6.1), indicates that for platforms with 1 GB of RAM and Android 8.1, Go-mode MUST enabled (flag android.hardware.ram.low).
LineageOS 15.1 Go Edition is fast enough, but Go-mode is not compatible with many programs running in the background.
Therefore, the optimal version is LineageOS 14.1
Thank you very much for your precise explanation. As I see you are also the Developer of Lineage OS 14.1 for Eagle:
https://forum.xda-developers.com/xperia-m2/rom-lineageos-14-1-t3919879
I have looked at your GitHub Repositories. Can you help me to port your 14.1 code to Xperia T3 (Seagull)?
T3 is also Yukon based and some Dev made the first steps: https://forum.xda-developers.com/xperia-t3/testers-development-twrp-lineageos-14-1-t3725791
So I hope it would be only quite-difficult ... :D

I own the real device, have already compiled, flashed, booted and worked with AOSP. Unfortunately stuck with the camera but could not get help:
https://forum.xda-developers.com/xperia-t3/rom-basic-fast-rom-d5103-help-camera-t4109727
It seems T3 is not a very popular device amond devs. So my hope is to find a "Yukon-Brother/Sister" :fingers-crossed:

2021.01.18 - For M2 Dual (D2302) – fixed the ability to disable the second SIM in the Settings.
We had a long-standing bug on the M2 Dual - there were no files needed for the options to disable SIM cards in Settings.
I was informed about this recently and has now been fixed.
Report any issues you find, many of them can be fixed.

Hi i am doing this for the first time and i was just following your steps when i reached this one.
  • Do Factory Reset in TWRP (necessarily, otherwise the installation over the old LineageOS inherits some errors of the old LineageOS). I recommend doing an additional cleaning (this solves the problem with «update error 7»): TWRP – Wipe – Advanced Wipe – Dalvik,System,Cache,Data.
After i do this my phone gets stuck in a bootloop ? what did i do wrong ?
Also i already repaired the software using xperia compgion.

And i cant get into twrp recovery anymore it just gets into a loop. does this mean i have reflash twrp recover?

After a reset in TWRP, you do not need to leave it, but you must immediately install a new firmware.

If you exit TWRP after a complete cleaning, but before installing a new firmware, then there will be a bootloop, because there is no operating system.
In this case (with a bootlap), you need to turn off the phone (OFF-button near the slots that is pressed with a needle, or by holding Power + VolumeUp for a long time up to three vibration signals), and then turn it on while holding VolumeDown for a normal TWRP entry.

Also i already repaired the software using xperia compgion.

Flashtool or Xperia Companion reflash the bootloader and remove TWRP.
You need to reinstall TWRP according to his instructions ( https://forum.xda-developers.com/t/...t-discussion-2021-01-18.3923414/post-82966117 )

Well thank you i am officially an idiot hahaha i jumped the gun anyway everything is ready now gonna try again in a moment.

Thank you for the quik reply

Edit: Well i tried it and it lives!!! hahah it works good , little bit sluggish though while opening apps not much diffrence compared to stock firm 5.1.1.

Thank you for your service!

anyway i am going to try your other rom aisop and the older version maybe also the go variant try some others aswell. i saw in your howto/download page this is fun kinda exciting.
Also i really like your whitepagesite with all the info in one place very handy and organized.

This is a trail run for me i am going to give this phone to a relative.
am gonna put custom rom and try root with another even older phone until finally i am gonna do my better half the other side of the dynamic duo sony xz1 compact.

Edit2
Is it normal that firefox keeps crashing when i try to open it ? does it mean it cost to much ram to open? cause other browers like brave(very fast) and vivaldi i can open en run no problem.

Edit 3
Is there way to delete apps that came with the rom i can only dissable them forexample the browser?

Edit 4
Update I used all the roms in your page and they all behaved the same in terms of speed even the go variants?.After i saw they all behaved the same i wanted so see if they all can run firefox noone could they would all crash when trying to open firefox browser.

however i dont know what happend but i was running 14.1 los and firefox crashed after running it and was playing around with it and i had prevouislly used a stopwatch to test how long it took to open the apps and they al had the same time give or take then i used the batterie saving mode and started noticing the phone got faster? eventhough it says it should slow down it really got noticblly faster smoother when swiping araund and even saves of some time when opening apps compared to the normal mode and then i tried doing it to 15.1 los and then it worked the same slowish in normal mode faster and smoother when using batterie saving mode.

Yes. There are some programs that don't work here. The problem is with the kernel and will probably be fixed later.

With root rights, you can delete some apk files. But I do not advise deleting the browser, it is needed, for example, for authorization in some public Wifi networks.


I used all the roms in your page and they all behaved the same in terms of speed even the go variants?
1. In Go-versions, background processes work more economically.
2. The difference is noticeable in multitasking and heavy applications. For example, in Go-versions, the Yandex-map works faster.
3. The transition between regular and Go-firmware has some peculiarities. When installed over the old one - TWRP automatically edits the options of the new firmware by analogy with the old firmware. For the correct transition between Go-version and normal-version, you need to clean up /system /data before installing new firmware
4. After installing any firmware - background cache rebuilding may take several hours. Conclusions about the speed of work should not be made immediately.

In saving mode, some of the background services do not work or work less frequently, so the phone is faster.

[/QUOTE]

I thought that was weird that it got faster cause with my daily sony xz1 compact with stock firmware when i turn on batterie saving mode it becomes very slow and almost like stutters hahahahaha.
Cant wait to put a custom rom on it those bastards at sony stopped updating it after only one android version worse they stopt not long after even with security updates.

For example, new Xiaomi has two levels of battery saving. At the usual level of economy, the interface becomes faster. At a strong economy level, slower.
We will probably also have several levels of savings in the future (this is related to the kernel).
