I know this thread isn't recent, but I'm replying because It shows up for people when searching on the internet.

I was looking for custom roms for this device for a while, and didn't notice it's treble-compatible, so we don't need a specific rom and it's pretty easy to upgrade to a custom one.

You just have to:

1 - Unlock the bootloader (there are several youtube videos explaining)

2 - Install twrp (there's a thread on xda about that for the a01 core)

3 - download and flash a compatible GSI rom. I recommend installing the treble info app to be sure about what architecture and binder you have, but mine says arm32 and binder64

And that's it. You can even install android 12 or 13 on it, if you want.

I didn't know about project treble before, and it looks like a great step forward for us.

I have done that using a patched stock recovery with fastbootd (TWRP didn't seem to properly flash so I went that way), I flashed an Android 10 GSI and it works amazingly great, no problems yet, longer battery duration, faster performance, there is no downside. You are right, it is binder64 arm32. Why did I flash an Android 10 and not 11+? Because cat /system/etc/ld.config.version_API.txt \ | grep -A 20 "[vendor]", returned namespace.default.isolated = false, which, according to this site (in spanish, you can translate the highlighted part), means that I can flash only a GSI ROM equal to the stock android version, I haven't found any other source so I don't know whether this source is gibberish or this doesn't apply for every device, but I didn't want to try it. Any idea about this? Have you tried flashing an Android version 11+?
[Android Q&A, Help & Troubleshooting] mayehiranda:
I am fairly new to messing with phones, but I have a fair bit of pc experience. Could you explain where did you get that Android 10 GSI?
[Android Q&A, Help & Troubleshooting] unluckyuser:
Thank you for pointing that out and sorry for taking so long to respond. I flashed android 12 and found no issues so far. I didn't know about that restriction, so I will search about it later. Perhaps it can be something like the manufacturer not guaranteeing that a later version will be functional, not that it won't run at all.

I'd love to make some more experiments, but I don't have more modern devices to play with.

[Android Q&A, Help & Troubleshooting] SuperPotato3000:
I'm sorry for the very late response, I used the phhusson GSI repo from GitHub, in the releases version, I used the v222 version which was the latest one with 10, it's a bit dated but it works very well. https://github.com/phhusson/treble_experimentations/releases/tag/v222
[Android Q&A, Help & Troubleshooting] SuperPotato3000:
Hmm, sounds nice, does it run slower than the android 10 from the original a01?

Also, unrelated question, how did you flash it? Did you modify recovery so that it can use fastbootd or did you just install through Odin?
[Android Q&A, Help & Troubleshooting] mayehiranda:
what gsi is that? I managed to get flashbootd with patched recovery and tested many gsi, but all had issues with sim card or earphone
[Android Q&A, Help & Troubleshooting] unluckyuser:
I'm using the AOSP rom from trebledroid (arm32, binder64, ab, vanilla). I just checked out and I have working audio, but inserting a sim card doesn't work :(

I didn't notice it before, because I'm only using it with wifi, but it's a huge issue...
[Android Q&A, Help & Troubleshooting] unluckyuser:
It seems to run faster, but I'm using a rom with no gapps (AOSP rom from trebledroid [arm32, binder64, ab, vanilla])

I tried some ways to flash it, but ended up using odin. First, I used the repacksuper script for linux from this thread to create a flasheable tar file. Then, I uses odin to flash vbmeta and the packed gsi rom.

I thought it was working 100%, but I didn't notice that sim cards aren't working. Did you get a sim card to work?

Ah, one more question: Are you using the gsi with a or ab partition?
[Android Q&A, Help & Troubleshooting] SuperPotato3000:
I'm also using a room with no GApps, I also tried Odin but it failed for some reason so I ended up finding some guide that used fastbootd.

I only flashed the system partition on fastbootd, maybe that's why sim cards don't work on yours, maybe in the worst case something wiped device IMEI.

With this GSI (a/b partition), sim cards work well, I can do calls (although I never do it on this phone), use network data, and it works decently well

Also I never flashed vbmeta in fastbootd as it wasn't required in the guide I used and it still worked, is it needed on GSIs?

[Android Q&A, Help & Troubleshooting] a9381:
how to use fastbootd for this device?
[Android Q&A, Help & Troubleshooting] unluckyuser:
This is interesting. I never used fastbootd, but it looks like a good method and less troublesome, by your description.

The vbmeta is described as needed, in orger to disable the verified boot, but I don't know much about it.

Can you point me to your exact rom used? I will try flashing it with odin and see if the sim card works. If not, I will flash the stock rom again and redo it all with fastbootd to compare the methods.
[Android Q&A, Help & Troubleshooting] unluckyuser:
Update: I flashed an android 10 gsi with odin and, indeed, sim cards work normally.

I think you're right about that and I was too hasty to ignore it. I searched a bit more, and found this, in the official android documentation: https://developer.android.com/topic/generic-system-image. Apparently, it means that this device doesn't offer full vndk support. Perhaps, there's a workaround, but is goes beyond my knowledge.

It's quite disappointing, because having to use the same android version defeats part of the purpose of flashing a custom rom, but, at least, we can get rid of the stock android go limitations.

I tried searching for a rom based on android 10, but with the latest security fixes (android 10 was supported until february 2023), but found none. I have not enough memory and storage to build it myself, so I've hit a wall here. If anyone wants to help, feel free to contact me.

Thank you.

Do you remember why did you choose the vndklite rom? My treble info says "VNDK is not in the lite mode", so I guessed it wouldn't be compatible with vndklite roms.

For reference in this thread, my full treble info is:

The phhusson android 10 v222 gsi I used is the latest one that used 10, at least by him, it's dated and has June 2020 patch iirc, although it does not really matter for me, I have wanted to update it to 12 but now after seeing that SIM issue, I guess I will stay on 10, I'm trying to compile a GSI on wsl but I'm stuck at cloning the full android repo that even with a 1 Gbps network takes hours to only get to a 12%, I guess I will leave it downloading some day in the background if I don't keep forgetting.
[Android Q&A, Help & Troubleshooting] SuperPotato3000:
It's not a really complex operation but it should work, it patches recovery, in which you could then go to fastbootd mode while in recovery. Remember to get a backup copy of recovery from a original Samsung ROM for your a01 core, you only need Odin and GitHub so that you can use actions to flash recovery.

Thankfully, there is a full explained guide on the repo itself, so that there isn't more risks of ending up in a brick because I didn't explain it well.

GitHub - Johx22/Patch-Recovery: CI service that patches recovery.img of Dynamic Samsung devices launched with Android 10 and above to enable fastbootd.

I managed to find a rom with the latest security patches from february 2023. It's the build from LeOS and can be downloaded from here (the binder64 version is the one called a64). This rom is working fine for me and is the best I got. It comes with a few apps, microg and root access, but we can remove it all. If anyone wants to install it with odin, I uploaded the prepared file here to save your time.

If you just want the latest files to do a single build and then delete the repo, perhaps you can do a shallow clone to save a lot of time.

Mind if I ask what rom you intend to build?
[Android Q&A, Help & Troubleshooting] SuperPotato3000:
I'm gonna try again with something that is more pure, I guess I'm gonna use some more pure android source, maybe even AOSP itself but I'm gonna currently try using the one on phhusson's compiler, maybe it'll work, I have no idea.

@unluckyuser How did you make a file compatible with Odin?
[Android Q&A, Help & Troubleshooting] unluckyuser:
When I read your previous comment, I wasn't so attentive and didn't notice that you mentioned the sim card working, sorry. That's curious and shows that the cause for sim card not working in the other gsis isn't because of the "namespace.default.isolated=false" issue. I will check that rom and see if I can find out more about this issue.

Also, I didn't know about that wiki. Thanks for contributing.

I used the method from this thread. I ran the script with the stock rom and the desired gsi as input, and it repacked the gsi in the odin format.

thanks in advance for your comments!
[Android Q&A, Help & Troubleshooting] unluckyuser:
Hello. I flashed a LeOS GSI based on android 10. I believe I linked it in a comment above in this thread. I used that rom, instead of more recent versions, because it worked 100% fine, while I had trouble with mobile communication and something audio-related that I don't remember (I didn't try mtp to know if it worked or not), when using roms based on more recent android versions. The reason for choosing LeOS, was because it was the only android 10 rom I found which had the last security patches released for that version. I didn't use fastbootd or twrp, but flashed the GSI rom directly from odin running on a virtual machine with usb passthrough.

I remember that some people later reported having mobile data working on more recent roms, but I didn't try again at the time, because the rom I used wasn't too outdated on security patches, and I already had all my stuff configured. However, after a year without security patches, I'm getting more worried, so I've been thinking on trying another one, but I'm still keen on reconfiguring all my stuff and I know no way to easily back up a phone to install another GSI.

The link you posted isn't working for me, but you need a rom that completely matches your system. In this case, it must be an arm32, binder64 (sometimes written as a64) rom and with partition style ab. I recommend first trying roms based on maintained android versions and in case something doesn't work, trying older ones.

The trick is to start the SP Flashtool progress before you start the device and plug in usb. Because for a brief moment it will be in download mode on boot. Thats at least how it worked on mine. If SP Flash tool recognize the usb connection then it will lock it self in download mode until everything is flashed.
[Android Head-Units] juanarg3n2007:
Ok, but i have two doubts.

1 .My usb wire m-m is 3.0? is any problem with that

2 . Can you explain me with details the step in order to get the downloadmode?

I understood first i have to set de SP tool, click in the " play buttom", power the HU and then connect de usb? power on and connect the usb must be at the same time?
[Android Head-Units] Steefzar:
What i did is that i had the usb connected. Then just cut the power and add power again. I dont think the cable should matter. If the driver is not right you can have device manager up when you add power and you will for a brief moment see it there so you can update the driver. You gotts be fast though
[Android Head-Units] juanarg3n2007:
I ´ve followed videos how to install the drivers and i did it as well. The first time i connected this it´s worked for me because i saw the "OK" green but after that th HU wont boot. No when i power on i only see a short blink on the screen but anything more.

Ah, and i never hear the sound when the usb is plugge (tucutun)

Any more ideas? Did you had the same problem like me?

Oh then i think i am out of ideas. Like i got the USB sound when the USB was plugged in and gave it power. If you dont get that i dont really know

Hi good folks!

I want to upgrade from a note8 to a new phone but the more I read the more questions I have. I have chosen to settle for the 20 line because of the card slot and s21 and s22 don't have it. Apart the SD card slot, I need a long sot and great caméras (i travel à lot)

Anyway I have a couple of questions and I hope you'll be able to answer them! Thank you!

1. The note20 ultra has a variable refresh rate. Does it means it can do 1440p at a vrr of 45 to 120hz? And it also means the sot lasts longer?

2. The s20 ultra has a bigger battery and in most of the tests the sot is between 10 and 13 hours. Compared to the note20u at 7 to 10. Is that what you've seen also?

3. Cameras. The main camera picture quality is almost the same but I wanted to talk about selfies. I think the s20u has better selfies than the note. Is that true?

4. A 3z5mm jack would be a blessing but they dont produce it anymore?

Which one would you chose? Or maybe I should go with another phone like the Xperia 1 Mk. 3? Or maybe the v60?

3. Camera on Note 20 Ultra is better then S20 Ultra. And S20 Ultra has focus issue. But if we look wide then there are many scenarios which depends of light, background and situation.
