[GSI][13] LineageOS 20 TrebleDroid-based

[AndyYan]

Tried but there doesn't seems to be any files in both framework-res.apk and the vendor's framework-res that can fix it.

Make your own measurements, although there doesn't seem to be many writeups on it. I should probably sum up how I do overlays into a post some time...

1) how to chnge bootanimation? there's no /system/media folder...
2) how to make /vendor rw?
3) how to DisableForcedEncryption?

1) /system/product/media
2) Most likely you don't, esp. if it's EROFS on many newer devices.
3) Again, most likely you don't, as fstab is in /vendor and consequently RO.

Thank you @AndyYan for latest build lineage-20.0-20230325-UNOFFICIAL-a64_bgN google is working properly so far.

Hi, working great so far on Samsung S20 FE (Snapdragon).
Using lineage-20.0-20230324-UNOFFICIAL-arm64_bvN-vndklite.img .

Just one 'issue' (not really but it's easy to have sometimes to stop some apps from complaining), is there a way to enable signature spoofing?
I've got microg installed, working fine, however it is reporting the "System has signature spoofing support' (checkbox is checked) but the 'System grants signature spoofing permission' is unchecked. Is there a way to enable signature spoofing permission?

Thanks for the great work!

Definitely weird to see this report. Will have to test for myself on both of my Samsung devices, they both have pens (a phone and a tablet).

Did you test your devices with the pen?

Use Link2SD or /system/app mover or any similar app that does the same thing to move the app into system. This should fix the issue.

Someone told me that I should make a custom overlay to fix the issue. But, I haven't found any Youtube tutorial or written tutorial about it.

You should make one so that people with the similar issue will be able to fix it.

I didn't, and wont be able to for awhile. I'm back on the stock firmware, no gsi, for now. Perhaps in a few more days I will install a gsi again. Been busy with lots of stuff outside tinkering with Android.

There's your cue...figure it out yourself, make a tutorial, publish it.

just got one of your builds running on my Tab S6! Thank you so much!

Fixed two-pane layout in Settings for tablets - set an appropriate density then force stop Settings for it to take effect.

Unfortunately, I am not 100% sure what you mean by setting an appropriate density...

Could this post be helpful not to repeat any work?
Maybe you could quickly look over it and let us know if that is still the way to go? Or even include it in OP such that everyone knows from the beginning

 

[AndyYan]

Unfortunately, I am not 100% sure what you mean by setting an appropriate density...

Both tablet UI (taskbar) and two-pane are enabled on sufficiently small (albeit different) display sizes. I don't think the setting in Settings - Display size and text would go that low though, so instead one either set a large enough Smallest width in Developer options, or a small enough density via ADB.

Could this post be helpful not to repeat any work?

This mainly outlines getting values from stock, but sometimes stock provides no or dummy values (they can store values in other partitions or under entirely different keys).

[Edit] - I can rename boitanimation.zip, but I can't copy my bootanimation in media folder.... Help

2) I don't have erofs, I have a samsung device (a137f). I must edit /vendor or atleast repack vendor.img.... really.. because I must DFE to make twrp working... I tried DFE zips, they aren't working.

I am currently trying to flash this GSI on my Samsung Galaxy Tab S4 (gts4lte), but am not succeeding.

I managed to install TWRP (unfortunately only the WIFI version is available, but others say it works for the LTE version as well). Afterwards, I wiped the usual stuff and tried several different procedures

1. Flash GSI, then dm - verity disabler (as explained in a different forum by a guy who got LOS 17 running) => stuck at bootanimation of lineage
2. Flash patched boot.img to remove dm-verity, then GSI => stuck at bootanimation of lineage
3. Flash GSI, then dm-verity, then Magisk => stuck somewhere earlier, don't remember
4. Flash GSI and multidisabler.zip => same as only flashing GSI
5. Flash only GSI => reboots all the time not even proceeding to bootanimation of lineage.

These steps were repeated using the a64_bvN, arm64_bvN, and arm64_bvN-vndklite images.

The Treble Info app shows the following information:

Also, the Wiki has an article on how to install it on this device, although already from some time ago. Somewhere else, I read that from Android 10 onwards one should use the arm64_b images instead of the a-only. The only thing I did not do was flashing a custom kernel. However, I believe this is only done for disabling encryption. Please correct me if I am wrong.


So, could anyone help out? Did anyone experience a similar problem? Since it is stuck at the lineage bootanimation logo I suspect dm-verity and encryption do not play a role? Do you have any hints or ideas what I could try to make it work? Maybe LOS 19?

I am thankful for any hints or any information regarding this issue!

EDIT: if anyone faces the same problems see this post. Actually, as far as I can guess the reason causing all these problems is that FDE is used instead of FBE...but this is just a guess.

I mounted system.img
but I need 10MB more space... and... what I can delete?

Hi, what alternative Gapp (OpenG, etc..) can be used with Lineage OS bvN Treble ?
With both 19.1 and 20 I get the error of the /system partition that cannot be resized.

Cheers

The system partition is created with the EXT4_FEATURE_RO_COMPAT_SHARED_BLOCKS flag. It's basically read-only, can't resize, can't edit anything.

Your best bet is to go with the BgN version with Gapps built in.

Yes, but I would like to deGoogle my phone as much as possible.

I need only to pass the Safetynet and have the minimum of Google Service . No default app's
Should not be that one of the purpose of LineageOS ?

Jokes a part , can I manually de-Google BgN afterword with De-Bloater (for instance)?

Is there a list of the Google app/services included in the BgN so I know what to clean up reducing the risk of killing Lineage?

Use Link2SD or /system/app mover or any similar app that does the same thing to move the app into system. This should fix the issue.

Thanks! Still a bit new to these android 'internals' (depends on your level of comfort with it I guess ..)
However, if I use the /system/app mover or Link2SD, it complains about too few storage in the system-partition.
Checking it with some other app, indeed, the system-partition is almost full so no room to move the app to it.

Is there a safe way to enlarge the system-partition? If I boot into twrp and resize, I guess it should work? I've done it a couple of times on a Linux desktop but don't know how well Android behaves as a Linux system...
I'll try it later this week but maybe somebody has more experience with it?

EDIT: just saw the responses above about the system-partition being read-only, will have to find another way or just live with it I guess.

Well, Resizing the partition is kinda hard depending on what device you use.

But, an easy way of doing it is by flashing a gsi .img which is larger than the Lineage OS GSI .img using fastboot and then, flashing the Lineage OS GSI .img using TWRP.

This will leave some space because TWRP doesn't resize partition when flashing while Fastboot does.

Or, If you want, you can remove some system apps that isn't needed for the system to function.

And regarding the read-only system issue, use .imgs marked with VNDKLITE to make system rw.
