not boot , i tested,

Which ROM you did test?

s9+
e-2.7-t-20250220-UNOFFICIAL-star2qltechn

ok. thanks for your feedback. I used LOS19 for the S9+ because I did not find newer ones. The highest chance to work hast the S9 build

Thanks I will go back to the previous version

Thanks for the detailed information. What really helps for building is a manifest file and some building instructions. Then I can build a ROM for testing, I think the A13 is worth testing…

Ok, another try, sources are slighly different now:

Thanks for keeping the S9 Snapdragon Alive @ronnz98 !
I’m using your 2.3-t Build on mine and its working ok, some bugs and hiccups here and there but it seems that this device still have a lot of life on it!

Will test the new builds and report back! If you need a tester I can help!

Update:
Flashed the e-2.9-t-20250323-UNOFFICIAL-starqltechn.zip and got stuck at Galaxy Bootlogo with Set warranty bit: Kernel,
doesnt go any further than that.

Used TWRP 3.7

Did you perform a clean install?

I’ve did a clean install, before I was on /e/os 2.3-t.
I’m getting problems with data mount on my TWRP after any rom Flash, it seems that data partition start giving erros after a reboot from system.

Will give it a try when I got back home, thanks!

Ps.: I believe this error (stuck at Set Warranty Bit: Kernel) is a common problem with Android 13 based roms on SD845 devices, at least the S9. I’ve tryed another rom before and got the same issue.
Mind to tell whats the difference between the kernels used to build this one?
Thanks again!

I can share the kernel sources for both.
Does the new ROM also not work?
Where did you get /e/OS-T 2.3 for this device? I did not make this build…

Got it from here:
[UNOFFICIAL BUILDS] Samsung Galaxy S9 & S9+ (Snapdragon) for /e/OS-S - #4 by ronnz98 (was 2.3-s , sorry)

I need to get home and do a backup of some stuff before testing, will report back in a couple of hours if it boots.

Update:
Nope, still doesnt boot.

Stuck at Set Warranty Bit: Kernel.

Tried flashing through TWRP and with sideload.
No error at flashing, but when rebooting TWRP it shows “No OS Installed” after sucessful flash.

it is an expected message, when installing a custom android for the first time on a device,
if the flash was successfull, you generally can boot to system, despite the false “No OS Installed” warning.

Yep, thought that also, but it just get stuck at boot screen, so its a no go, at least for the moment.
Let’s hope @ronnz98 finds a way :smile:
