That's not even a valid error. The error your getting is because your building it in the wrong way. This is either a first time attempt or a cry for attention. If u want to compile a kernel use linux since these errors don't exist if you have working terminal with tools downloaded

It's not big errors. It's stupid attempt

---------- Post added at 11:22 PM ---------- Previous post was at 11:19 PM ----------

If you really wanna help, download linux and don't waste your valuable time on a random attempt that won't work. Trust me. The time you waste with this you will regret.

Oreo kernel is compiled..Now im going to test it..Problem with screen is cuz grafic driver is missing..
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] ConeSRB:
Kernel is not seandroid enforcing...
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] D@nijel:
You're wrong...

Kernel is in Enforcing mode (Android 7).

For Oreo you need to disable enforncing mode to boot up oreo because you don't have new SE Rules for Oreo fw, hw and sw ^^

Hello! my samsung J3 2016 model is SM-J320F/DS. which version should I install? SM-J320F/G/M (j3xlte) or SM-J320FN (j3xnlte)? thanks in advance.
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] Benfatica:
The j3xlte of course
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] anxaadbg001:
Thanks!

I'm currently using a custom ROM version of Resurrection Remix (RR-Nv5.8.5-20180831 -j3xnlte-Unofficial) but I want to try this Lineage custom rom. Probably there is no answer to my next question, because I've googled my problem but there's no answer, but I would just like know a bit much about it.... So, an issue comes when I try to make and receive videocalls on Whatsapp: app crashes with black screen. It's a problem for any custom rom? VolTe concerns something? I've try to reinstall the app but the problem is the same...
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] Benfatica:
Yeah it's a bug but it has been fixed on the 20181025 build

Here is the official link https://drive.google.com/file/d/1pxPlN6u1jpdHXaoU_mbfwVC5ae04ekCL/view
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] anxaadbg001:
Oh yeah! thank you so much! :D now i'll start to backup all my data and start to install this lineage custom rom. I just need to click the link that there's on description, in the opening of this thread to get the latest version? edit: seen now your edited link :P

---------- Post added at 02:53 PM ---------- Previous post was at 02:47 PM ----------

uhmmm... so, what do you suggest me? Try Lineage 14.1 or just go to update RR?

Thanks
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] Benfatica:
Go for the update

But if you want security update go for the lineage os. But I am using rr .
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] Tommytommy1234:
If you use lineage too, did you notice any difference in performance and battery between los and rr?
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] Benfatica:
Enhh almost the same I only use rr for the customization and substratum theme.
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] Wellingtton_silva:
ViperOS is better at performance and theme flows better in it

[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] anxaadbg001:
At the end i have erased all and tested ViperOS. It was ok for some days, until 2 days ago i have rebooted phone and a green message appears: "custom binary blocked by FRP lock".

I couldn't do anything because phone was in bootloop, so i erased all, reinstalled stock rom and again re erased all to install Resurrection remix again... But after the first time that i rebooted my phone, it reappeared the message "custom binary blocked by FRP lock" and phone was in bootloop again...

What i have to do to resolve this problem?

[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] anxaadbg001:

Yeah.... I was thinking about what I did.....I'm pretty sure that i turned off the developer menu.... this to prevent to turn off accidentally OEM in the future..... but now i realize that if you turn off Dev menu, you'll turn off ALL dev options, including OEM unlock. So, i have a question: there is an apk, or a script that put a protection for accidental touches over this menu or OEM switch?

Yes, you can force all apps to be movable to external storage by enabling "Force allow apps on external" option in developer settings. However, this doesn't apply to system apps (although this is also possible but with different procedure).

Probably because it's still being rolled out, I'd imagine until it's available on the majority of LOS supported devices they won't include it in LOS to avoid the false bug reports (some devices will probably never support it after all).

[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] RongYao:
Oke i've tested both roms, seems both LineageOS 13 / 14.1 doesn't respect the network type preferences. Might be a bug, because i have 4g preferred but it connected to 2g, i use dual sim so i've noticed something was awkwardly not right, because both sim cards was set to 4g preferred, phone cannot work with 4g on both sims ye, instead both of them worked on 2g regardless.

Just go to your network switch both to 2g and then switch first to 4g, that should disconnect your sim for a second, then you will see lte in the status.

Try dialing *#*#4636#*#*

then choose lte gsm.

Or you can edit the build prop file.

telephony.lteOnGsmDevice=1

ro.telephony.default_network=9

ro.ril.def.preferred.network=9

0 WCDMA preferred

1 GSM only

2 WCDMA only

3 GSM auto (PRL)

4 CDMA auto (PRL)

5 CDMA only

6 EvDo only

7 GSM/CDMA (PRL)

8 LTE/CDMA auto (PRL)

9 LTE/GSM auto (PRL)

10 LTE/GSM/CDMA auto (PRL)

11 LTE only

12 Unknown

That should do it.
