thank you so much Mr.Erwin, it works perfectly on my sister's device
[Samsung Galaxy J1 ROMs, Kernels, Recoveries, & Oth] kotiklolik:
I think this is a very good ROM (Lineage Os 14 SM-J100H).

By the way, I found a solution to the root problem. I was installing the Magisk zip file via TWRP but kept getting error 1. So, let's get to the solution (I'll also include some helpful screenshots):

0. Make a backup in TWRP. Everything works for me, but I don't know how it will work for you since I did this on a freshly installed ROM. I am not responsible for your device!

1. Install the Magisk APK (it will be needed for patching boot.img).

2. Download the zip file of the ROM again and open it.

3. Inside, there will be a file without any type or format named "ErwinAbs".

4. Copy/extract it from the archive.

5. Rename it to have a .img format at the end, resulting in "ErwinAbs.img". I renamed the first part differently to "maybebootlineag14.img" because I had a hypothesis and was not sure, but it turned out I was right. You should also make sure that you are not just renaming the file but setting the .img format so your system recognizes it as a disk image file.

6. Upload this file to an SD card (that's what I did) or to your phone's storage in any way you prefer.

7. Launch the Magisk app and click on Install Magisk. In the options, don't select anything, just click next. In the method section, choose "Select and Patch a File", select our created "ErwinAbs.img", and click "LET'S GO".

8. If you did everything correctly, in the end, Magisk will write "-All done" in the console. Also, remember the path where the patched .img file is saved (this is also written in the Magisk console).

9. Boot into TWRP, then wipe Dalvik and cache (two separate options (UPDATE: If there are problems, you need to wipe dalvik and cache, but you don't need to do it specially, I have now installed gapps and Magisk root and everything works fine without a wipe)). I did this just in case, it might not be necessary (note that installed GApps might disappear). Next, go to the install tab, select the install .img button at the bottom, find our patched image, and install it to the boot partition (this is selected during installation).

10. Reboot into the system, and you're done!

This way, you will get root access. I needed it for RAM expansion, and if you need an app for this, I can provide one, but I rarely visit XDA, so I can't guarantee a timely response. By the way, you can rate my English level)

installed & still booting ( 30 min now )

does the xposed work with this rom just to download as it boots up?

edit 01 : after nearly 1 hour i had to pull battery out & redo the hole setup again

thisis going for 10 minutes now i'll update when finished or crashed

edit 02 : phone booted with only rom installed i'll try the gapps v7.1 pico to see if it hangs out

also forgot to flash the fix the first time so i'll see if it boots then i'll do it else i'll reflash rom again & try in the good order.

edit 03 : rom booted & installed the following:

-fix

-xposed framework

-magisk

seems to work fin i'll update in few days to give feedback

thanks for replying.

I applied the fix for using the back and recent buttons, as in the threads above mentioned.

I asked already in the other thread: Which ROM would you recommend out of the CM, RR, LineageOS versions I can find?

And also: what steps can you recommend to make a custom Lineage OS 14 on the J100H (now that I have it, I want to do it myself).

Cheers!

Mobile connection was intermittent for both sims and unstable. This was the case after applying the Fix. About Device under Settings says SM-G531H. It appears the ROM is not intended for SM-J100H, please confirm. :)

Thanks for your input. Very valuable.

My main intention/motivation was to get rid of any Google connection. Thus I have no GAPPS installed and I am fine with the response time (but I am no smartphone user until yesterday anyway, so "response" time feels different for me than everyone else I guess.)

I see that SM-G531H as well. Since I have no experience in building my own ROM, I could only guess, but it might also be some partial injection from a SM-G531H ROM, like, e.g. the partition formatting etc.

I did not use it long enough to confirm the intermittent mobile connection. It worked fine so far.

This is interesting: AICP_5.1.1+FOR+J100H means this is a Lollipop custom ROM I could try as well, right?

Hi there, giving you a bit more background. In a Youtube video Erwin posted with a link to his blog for this ROM (thank you Erwin) his instructions said to first flash AICP_5.1.1+FOR+J100H, and that is right it is Lollipop. I then rebooted the phone and tested it. It recognized only one SIM. The response time was ok (sorry I should have been more specific), e.g. it took about 4-5 seconds for Settings to appear after clicking it, counting 1,2,3 ... 5. About Device said SM-G531H, checked memory used by Apps, was around 340MB about 100 MB free. Since have dual SIMs went back and flashed LineageOS4.1+SAMSUNG +J100H; Fix Lineage Os 14 and gapps-L-4-21-15, then rebooted the phone. The phone was real slow, clicked Settings button would take about 9-10 seconds, counting 1, 2, 3, ...10. Both SIM connections were intermittent, it could be attributed to low RAM, not sure. Memory used by Apps was about 400 MB and 30-40MB free. Browser was extremely slow, was able to test Bluetooth and share files but it said SM-G360H, not sure if it is significant.

Hope that helps.
