Are you working on an Oreo ROM???!!!!

You are amazing :D

red rectangle off crash

I have tested, i get a red rectangle over the display, a few seconds later the system crashes!

Works great, thank you.
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] moozer:
All power to you! Thanks for your commitment to this ROM. If feel the future of custom ROMs for this device are firmly in your hands.

Amazing job so far dude
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] moozer:
Damn! I keep getting reboots when using the phone app. Speaker issues have gone as expected, but as soon as I press to end call, the phone reboots
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] sakiometri:
Hi, I've just tested..

- speaker switching works now, but internal is so loud that it seems it's loudspeaker...

- something like strict mode is on by default (red border flashes around the screen) and it cannot be disabled

- random reboots.. while 20min tests 5 reboots.. - I had not any reboots on previous versions

(I did a full wipe dalivk,system,data,cache - first flash with gapps pico, but couldnt connect to get google sms - so next flash was without gapps.)

thx for work.. but this release is not for me :(

I've found 2017/08/22 release to be the best for me.. internal speaker works and all I need without LTE.. (no signal at all - have to change to 3g to get signal)

im in the last build and my screen sometimes flashes with a red framework, its weird. i will return to the last one
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] sovietnuke:
Yeah, I had this too, and I went back to a previous release. I think the last one is the worst one.

I also had a strange flashing red frame around the screen and reboots every few minutes...

Anyway, thank you for the hard work [MENTION=3463426]RaymanFX[/MENTION] !

Hopefully it will be fixed in the next release.

And I have a question. What is the best way to get into AndroidOS development??

I am programming Android apps in Android Studio and C# and Visual C++ Windows application.

Maybe there is a way I can help if I could learn this. Are there some nice and easy to understand tutorials where to start with this?
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] RaymanFX:
Strange, strict mode should not have been active in the last build.

How about this one?

[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] sovietnuke:
Thank you [MENTION=3463426]RaymanFX[/MENTION], phonecalls are not on loudspeaker now.
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] sakiometri:
Thx, I've just flashed it...

no problem with sound while phone calls :)

no strict mode :)

lte works but sometimes it gets lost.. after that I have to force 3g and reboot phone to get signal and after that i can change to lte and it works again.

One thing is strange, I didn't have it before - when I click in app switch button (or home twice) - phone is rebooting :(
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] moozer:
Random reboots upon using phone dialler remain. Speaker works fine
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] RaymanFX:
I don't have any unexpected reboots here at all.

Grab /proc/last_kmsg and upload it for me so I can take a look, otherwise there's not much I can do.

[MENTION=3463426]RaymanFX[/MENTION] I have random reboots too. But I didnt tried a clean install yet.
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] Timo64:

But thanks Raymanfx for your hard work

My A5, running lineage-14.1-20180129, was rebooting whenever I switched apps in recents. Disabling HW overlays in developer options fixed the issue. Here is what I was getting in logcats before the phone rebooted:

How can I install the nougat bandbase? I have the latest updated version of nougat (A520FXXU4BRA8) and to install the rom I need the first rom de nougat (A520FXXU2BQH4) but in the last patch it does not let a previous bootloader outdated and I get an error.

[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] snorkilator:
Could you explain in more detail how to do this or point me towards some info on fixing the issue please?:)
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] LORD239:
You can't flash for old BL. Odin will not downgrade version BL. And you will not be able to install any custom as version 3 and high bootloader locked.
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] D@nijel:
You need device specific config to this alongside lineage source code.

Look at HWC dir(hardware composer) :)
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] elcreepyFP:
Please read the thread before asking.

Just open the ROM file, META-Inf>org>google>android and open with Notepad++ the second file.

Then, delete all the lines above until the first line has the word "mount". You should have deleted 4-6 lines.

Then save the file, and close it. Try to flash the ROM again.

If winrar ask to modify the files after saving, click on Yes

After i had used my Bluetooth headphones, I have no song and it's the same problem after reboot.

I'm on the 20/01 version
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] elcreepyFP:
I had the same issue. You have to force stop all the apps that you used to listen audio like YouTube, Spotify ...

But if you don't have V4A installed, it should not happen :v
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] moozer:
These issues are addressed in latest build but the reboot error now exists. Rayman will sort it
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] sakiometri:
I'm also interested in this. So far I've found how it can be done for other phones:

https://wiki.lineageos.org/devices/hero2lte/build

RaymanFX has done a lot of hard work and shared it in on github, so I think all we've got in this thread is a combo of lineage & and this:

https://github.com/raymanfx/android_kernel_samsung_a5y17lte

https://github.com/raymanfx/android_device_samsung_a5y17lte

I haven't tried to setup this environment, but I think it's possible with this repos.

Check out and let me know if you find more info :)
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] AndreCalado:
Please, forgive me if it is a noob question, I'm new to Samsung devices. Can we use 'adb flash recovery' to flash twrp instead of Odin?

[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] sovietnuke:
OK, I am going to try now... Thank you.

UPDATE:

OK, I have working LTE now. I dont really know how. I Installed the Modem from Android 6, went to twrp and flashed the rom again, then it worked on first boot. Then after reboot, it stoped working.

So I set the APNs to default and reboot, then it worked again. It looks like, you have to be in 3G Mode, reset APNs to default, then set LTE Mode and reboot. After Reboot LTE is working until next reboot. Dont know if this works without the Android 6 Modem file....

Not sure if I missed anything in the thread, but:

can you guys provide dmesg and logcat output when the LTE was working and AFTER it has stopped working ?

this might help to find out what exactly is causing trouble (provided in this situation there is enough output) ...

This device really looks promising but without LTE it surely is a bit of troublesome (when thinking that my current contract uses LTE :eek: )
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] :
Waddup [MENTION=3463426]RaymanFX[/MENTION] , thanks for creating this rom. Unfortunately, the music problem still exists. When I listen to music through earbuds and I turn the screen off, the music stops. Here is a logcat.

Maybe it has to do something with this?

Looking forward hearing from you.
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] KaiKellner:
I finally installed LOS for this mobile phone.

Here in Germany LTE is working with the provider Telefonica (O2/ E-Plus) with one issue. The network must be switched to 3G then it automatically switches to LTE.

Very often after a reboot the network for o2 is not connecting automatically. It then has to be registered manually.
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] LORD239:
this is the log of the change from 3g to lte. And then off
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] RaymanFX:
I finally good a grasp on this issue when I was hunting audio bugs last week: it happens when ALSA output and input mixer paths are active, and then the input path is disabled. In that specific case, the audio path depends on some mixer controls that are deactivated by the input path, but the audio subsystem doesn't know about this.

This only ever happens (from what I can tell) when using Google Always Listening (aka "OK Google"), because that always makes the audio driver set the input path when the screen is on.

On screen-off, that always listening feature is disabled, thus the audio route is disabled and the output path is broken because it is not aware that the mixer controls changed.

A fix is here and will be integrated into the next release: https://review.lineageos.org/#/c/205013/.

Also, a note on RIL/LTE: I will not waste any more time trying to fix the current LTE bug. It will never be fixed. I will spend my time making the open source rild/libril stack work with our proprietary libsec-ril layer (which handles the modem communication).

The current, proprietary rild/libril will be useless on O anyway.

Once the open source rild/libril wrappers are working, LTE should work out of the box as well.
[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] :
Very good to hear. I'll try to disable always listening.

[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] AndreCalado:
oh, sorry, I meant a functional twrp. I could not flash or wipe anything, and after third or fourth reboot, only a red message were displayed when booting or trying to access recovery: something about the seandroid be not enforcing and that only official binaries could be flashed. The only working thing was the download mode, then I could return the device to a stock working rom.

And I want Lineage OS for this device very much, Samsung really does a great job, but I'm not their kind of user, I feel like all my freedom had been taken from me. I could not find a guide which makes me understand how to deal with its proprietary maze lol

No, if your EFS partition was genuinely deleted, there is no getting it back. If modem.bin were corrupted, the device may not turn on right, and WIFI would be completely broken.
