[GSI][13] LineageOS 20 TrebleDroid-based

This is a great way.

IF you are certain you only erased the vendor partition, you can also find the latest stock vendor image file and flash it using TWRP. There is a website for downloading the stock firmware but I can't remember its name.

smart assistant is the best to get back to a working device. I've used it several times.

I used this too as a base to extract the kernel etc for patching. I'm surprised that its such a good tool from the manufacturer. It will recover your tablet from just about any state except an actual hardware fault.

Yeah i am getting the same thing, and my audio randomly starts routing from my bluetooth headphones to the phone speaker but yet it still says my headphones are connected. the sound just starts playing through the phone speakers.

Does your device have a Unisoc processor?

If so, this issue has been fixed with the latest PHH build. Just waiting for the next LOS 20 build to be released with the fix integrated

I am trying to install stock ROM by using smart assistant. I am in third step, connecting the device by pressing volume up no response at all .. any idea? Edit: I purchased a brand new cable problem solved. For anyone experimenting with custom ROMs please make sure you are using quality cable

No, no, no. You don't wipe any partitions. You need the Lenovo firmware vendor partition to be there. I don't even wipe the data partition, and have had no problem. Treble firmware only works if every partition, except for system, is stock. I suggest you restore all of the Lenovo firmware via TWRP and reboot to make certain it still works. Then you can reboot to TWRP and follow my suggested steps.

Magisk is not required, but I use it.

I installed again stock ROM then twrp, I didn't make any wipe just install at system image but I got error again regarding custom ROM

 

[vassiliszacharis]

See the image edit problem solved changed the SD card use a trusted one! Edit 2. I am stack at leneage logo for a half an hour at a first boot... SNAFU (Situation Normal All Fu$_&#d Up)

 

[vassiliszacharis]

I am stuck at first boot leneage logo for more than an hour, not normal. I would be very grateful if someone please explain the steps I need to follow in order to flash effectively that particular custom ROM please

 

[AndyYan]

if you're going to test, maybe you might want to do so on a Samsung, as well as non-Samsung device.

Hey, it took me long to get to this backlog, but still no good news for you - the logs don't really ring any bells to me, and I was unable to replicate it on Samsung (Galaxy Quantum2) or not (OnePlus 11). I'll put this aside until another example pops up, sorry about that.

Have you tried installing Magisk 26.1 (available at https://github.com/topjohnwu/Magisk ? It solves a lot of compatibility problems.

Make sure you got the right image. On your tablet, the td based images are the only ones that will work from here:

Andy Yan's personal builds // GSI - Browse /lineage-20-td at SourceForge.net

sourceforge.net

The `lineage-20-light` ones will not work.

Cheers mate. Well what I actually did and worked was:
1) wipe: cache, dalvik, data, system, internal storage
2) format data
3) install leneage from SD card
4) reboot
And it worked like charm

Yes I know, I only use bgn

Glad it worked. After lineage stabilizes a day or so, you might try restoring your older data from TWRP (backup your current data first). This method has worked a couple of times for me.

If not a bug fix, then how about a workaround that let's the ROM boot without factory reset? Even if the logs don't indicate the cause, you could surely see that it was stuck in the booting process.

Or maybe I should submit this bug to phh.

I can give you another example, the behavior is exactly the same on 2 of my devices. I only submitted the logs for one because I use it more often, and encountered it there first. I guarantee you, I'm the first one to submit a report on this, the chances of it being independently reported by someone else are slim to none.

Hi @AndyYan.
Here's the logfile for the constant crashing for my phone (OnePlus Nord N10).
I've checked it and have seen some components crashing.
For systemUI, it's saying that "reason: crashed quickly".

Hello,
I'm new to GSIs and installed the light version (bgN) on my Tablet (Lenovo TB-J716F). Everything works nice but I get the warning "this device is not play protect certified", so I tried installing the TD-Version which works fine except for how the folder is displayed? I also can't set a folder name.

Does someone know how to solve this?

Use a different launcher. Lineage inbuilt launcher is trash, Trebuchet or whatever it's called. But I think this LOS uses a modified AOSP QuickStep launcher, instead of Trebuchet. No difference, QuickStep is just as bad. I personally use Nova, no issues with folders there. Installing Nova is one of the 1st things I do after a clean boot of any new gsi.

Any solution to "app not responding" appearing regularly even if the app is normal?

Agreed on the Nova suggestion, been using it for 5+ years and haven't looked back

Thanks @AndyYan ! With a lot of pain I was able to make your 20.0 treble-based GSI with GAPPS work on a samsung galaxy tab a7, and install TWRP on top of it.

LineageOS has this option on "lock screen" by wich the screen cativates itself to show when a notification arrives. I found it gets disabled when I enable power saving mode though.

Is there any way, maybe with adb, to be able to keep that functionality with power saving mode on? The stock UI (AFAIK or at least my a32's stock) has a more customizable power saving mode that allows to customize what the power saving mode does, and you can keep Always On Display working.

Thanks!
