Thank a lot man, great work. Someone testing in SM-531M ?
[Galaxy Grand Prime Android Development] TBackspace:
I tested on my sm-g531m and the call is not working...
[Galaxy Grand Prime Android Development] Nemirtingas:
This ROM is for SM-G531F
[Galaxy Grand Prime Android Development] Kolya45777777777:
GPS not working SM-G531F
[Galaxy Grand Prime Android Development] Nemirtingas:
It works on my phone.

Can you send the result of:

getprop | grep build

and

md5sum /dev/block/platform/soc.2/by-name/MODEM

?
[Galaxy Grand Prime Android Development] Kolya45777777777:
Can you explain more about how to fix a GPS problem?
[Galaxy Grand Prime Android Development] Erioernesto02:
Bro, SM-G531M have they same proccesor and drivers. It's possible port?

---------- Post added at 06:25 PM ---------- Previous post was at 06:02 PM ----------

Bro, you flash first a European firmware?
[Galaxy Grand Prime Android Development] Nemirtingas:
I'm much more active on Telegram: https://t.me/joinchat/KTfOchGJqAFSHZjDy20AGA

If you can it would be great that you post your bugs and questions here.

I don't know if it can be ported, and I wouldn't do it anyway. This ROM is not finished.
[Galaxy Grand Prime Android Development] costa11:
Excuse my ignorance What it means to clean everything except the internal and external gapps
[Galaxy Grand Prime Android Development] Erioernesto02:
I not test for now because I have a sm-g531m, but I think what not format internal storage Make a dirty flash and all your app and data is keeping.

---------- Post added at 04:05 PM ---------- Previous post was at 04:04 PM ----------

For me, a clean flash is better for first time
[Galaxy Grand Prime Android Development] Nemirtingas:
Wipe Everything Except Internal and Sd means wipe everything except External SD Card & Internal SD Card, so you should wipe system + cache + dalvik-cache + data
[Galaxy Grand Prime Android Development] costa11:
I did the wipe that you say, but I had display driver problems

I did a clean flash but I do not start the phone I have a Galaxy 531f
[Galaxy Grand Prime Android Development] costa11:
Sorry girls but I had to get out of the telegram because I did not want to be banned For nonsense I never said anything bad I just asked for help someone got pissed off because I'm asking too much information

Fix bugs?

Hi, I have a question when can I expect an update or fix regarding the invisible status bar and recent applications? It is very annoying.
[Galaxy Grand Prime Android Development] Nemirtingas:
Hi,

I'm still working on the ROM but I don't know for now why it bugs or how to fix it. Also I'm alone working on this, any help is much appreciated...

I've built cm-12.1 (the same Android version as the stock firmware) and the bug is already in there. I try to build a stable cm-12.1 so I can compare stock ROM with my custom ROM and try to find how to fix all this bugs.
[Galaxy Grand Prime Android Development] Kolya45777777777:
CM 12

Upload cm 12 on Google Drive. I want tested rom and detect all bugs)
[Galaxy Grand Prime Android Development] Nemirtingas:
Those bugs are now fixed !

Applist show the apps thumbnail and status bar not longer have a black background.

Lock screen is no longer laggy as well.

New download link uploaded.
[Galaxy Grand Prime Android Development] Kolya45777777777:
GPS

GPS does not connect to satellites. The system often reboots. I have g531f
[Galaxy Grand Prime Android Development] n4Suu:
I found 3 bugs, the first: AndroidOS with SystemUI sometime uses a lot of RAM. The second Internet from cellular data sometimes doesn't work automatically (You need to set the operator manually). And the last one is ROM low performance, after 5 minutes in chrome and freeze...
[Galaxy Grand Prime Android Development] TimaZ__:
I found a bug... Don't work listening via headphone.
[Galaxy Grand Prime Android Development] TimaZ__:
And ask:

will NFC and mobile Hotspot added and work?
[Galaxy Grand Prime Android Development] Antikiller74:
Finally a good ROM, I do realize that it's a beta, so I expected bugs to be in this ROM, so what I found out so far:

YouTube kind of works, but you get black screen only;

Reboots (mainly because it's overloading (my guess)

Earphones not working

But in general that's a really good ROM :D
[Galaxy Grand Prime Android Development] Antikiller74:
Well, I found a way to make the phone reboot less:

1) Enable dev options

2) Enable "Force GPU rendering"

3) Disable animation (Window and transition scale to 0.0x and Animator duration scale to 0.0x too)

If you're having problems with YouTube (black screen) - install YouTube Vanced, link a google account if you want and get in Vanced settings, then press misc and then tick "Enable ExoPlayer V2"

all of that worked for me, less reboots now
[Galaxy Grand Prime Android Development] Nemirtingas:
I'm impressed that someone uses this buggy ROM... Unfortunatly I might not be able to make it stable, Samsung and/or Marvell modified a lot of core Android's libraries so Hardware Codecs might never work and I'll have to disable em and use only software codecs, so no 1080p decoder/encoder...

If Samsung or Marvell could share their sources that should help a lot but it looks like they don't. I'm trying to build a los-14.1 actually as its a lot more stable than los-13.0.

RAM usage is better in los-14.1 but if I set a lock-screen, it won't go off. Any idea ?

I'll debug it when I have some time, I'm developping for 2 phones, this grandprime that is really a pain in the *** cause I have to create my own hardware sources and a Galaxy Grand2 for which I can rest a bit, its a lot more fun as the hardware part is working.
[Galaxy Grand Prime Android Development] Antikiller74:
"RAM usage is better in los-14.1 but if I set a lock-screen, it won't go off. Any idea ?"

No idea, I never edited or created ROMs or something xD

So when we can expect los-14.1? The stock ROM is just bad and it breaks like hell after a while for me, like yesterday it just kept freezing after like 5-7 mins, so that's the reason why i installed this ROM
[Galaxy Grand Prime Android Development] Antikiller74:
Checked for updates in settings -> about phone -> LineageOS updates, I see 14.1 there, but it says it's "blocked", it's out very soon?
[Galaxy Grand Prime Android Development] Nemirtingas:
I don't know if it will be out soon, and I don't even know if Ota works x)
[Galaxy Grand Prime Android Development] Antikiller74:
Yeah but it says that it can be updated but it says "Update blocked", so it's like in beta but not available atm?

Edit: I can test the ROM if ya want, just want it to not freeze after a while :D
[Galaxy Grand Prime Android Development] Nemirtingas:
It has too many bugs right now. Some graphic glitches and Wifi doesn't work.
[Galaxy Grand Prime Android Development] Antikiller74:
Yeah I see, can I test it after you fix these? Might find more LOL
[Galaxy Grand Prime Android Development] fabien976:
hello !

have you an idea for you release an update for fix bug and last android securituy ?

thanks for reply :)
[Galaxy Grand Prime Android Development] Nemirtingas:
Until Marvell release their sources (which they won't) I won't be able to use hardware encoder/decoder so no hd or fullhd. I'm using my own built los 14.1 but camera doesn't work and got a lil graphic glitch but its usable.
[Galaxy Grand Prime Android Development] Kolya45777777777:
When will the first build lineage os 14?
[Galaxy Grand Prime Android Development] fabien976:
what do you need ?
[Galaxy Grand Prime Android Development] Nemirtingas:
I need libstagefrighthw.so sources and the codecs sources.

Marvell and/or Samung modified the core Android source code and its really a pain to know and understand what they did.

I modified libbinder.do and libaudioutils.so sorces to make calls work and camera to start.
[Galaxy Grand Prime Android Development] Kolya45777777777:
When can I install ROM Los14?
[Galaxy Grand Prime Android Development] mrwrong00:
sim card is not detecting
[Galaxy Grand Prime Android Development] Antikiller74:
So here's the thing I noticed while hecking around in "About device" thing, I checked "Legal information -> Open source licenses" and I found things such as:

/system/lib/lib_il_aacdec_lnx.a

/system/lib/lib_il_h264dec_lnx.a (same goes for 263, 265 and others, both dec and enc)

So I'm guessing you need these files or something? Cause it's Marvell's things, so I realized you might need that info or something
[Galaxy Grand Prime Android Development] Nemirtingas:
No, thoses are static libs which are already in the enc and dec .so in the Rom. But thanks anyway.
[Galaxy Grand Prime Android Development] Kolya45777777777:
When can you expect the first build?
[Galaxy Grand Prime Android Development] fabien976:
for now is a codec problem for youtube video and sound with it
[Galaxy Grand Prime Android Development] Kolya45777777777:
What works in the ROM?
[Galaxy Grand Prime Android Development] fabien976:
Hello , already don't forget "hello" :)

now , what's work in ROM ?

the basis of the phone's functionality work as : call, text, wi-fi , settings....

when the system will be more stable :)
[Galaxy Grand Prime Android Development] Nemirtingas:

Less reboots.

Gps should be fixed.

Camera kind of works.

Keep in mind that any request/complain/bug/eta without logs will be simply ignored.

[Galaxy Grand Prime Android Development] Nemirtingas:
New version release, that should fix all random reboots.

And published TWRP 3.1.1.0 for grand prime.
[Galaxy Grand Prime Android Development] Kolya45777777777:

Hello. I am using the European 4-file firmware G531F_XXU1APG2_MDO1APG2. I used to install firmware recovery version 2.8.7.0. I found the following bugs:

1) There is no point wifi access point.

2) GPS does not work. When I check the navigation operation with GPS test, my phone will restart

3) Headphones are not detected.

4) Only 1000mah in the battery. I checked Kernel Adiutor.

5) I tried installing through recovery version 3.1.1.0. but the bugs are the same ones.

6) The kernels do not go into a deep sleep and the battery is discharged faster than the standard firmware.

7) Battery drain

Hello,

I just installed the rom and the pixel launcher stops working

some help,please?
[Galaxy Grand Prime Android Development] Nemirtingas:
Depends on the pixel launcher. As I can see its for android 7+ or android 8+, here it's android 6.0.
[Galaxy Grand Prime Android Development] victor325:

[Galaxy Grand Prime Android Development] ai1818:
hi.. good day. i just want to ask if this rom will work on my sm-g531f. mine is not xxu or xcu.. i have "ddu". will this work if i flash this.. thanks in advance
[Galaxy Grand Prime Android Development] PMFRTT:
Hey, thanks for actively developing on the Grand Prime. I only use it as my secondary device, but it's still nice to see development for this device taking place on XDA. I really appreaciate your work, as the Stock 5.1.1 was really getting old and slow.
[Galaxy Grand Prime Android Development] Nemirtingas:
If someone has a dual sim version of this phone (I only have single sim), can you post the result of

cat /proc/cmdline

As root ?
[Galaxy Grand Prime Android Development] pa.thewraith17:
I have one and id like to help. As of now im runnin on stock XXU1APG2. You want the result with the rom flashed or is the stock one okay?
[Galaxy Grand Prime Android Development] Nemirtingas:
Both if you can but I guess the result will be same.

I think the stock is the most important
[Galaxy Grand Prime Android Development] pa.thewraith17:
I will look into it. As of now im not willing to flash Lineage cuz this phone's my daily driver? I will try to send the stock result
[Galaxy Grand Prime Android Development] pa.thewraith17:
As im running on the firmware you provided it doesnt seem to recognize sim 2? Heres the result anyway.

Sorry i couldnt create a text file. Was on a rush. If this doesnt help, let me know i'll flash my native firmware and provide you the result. Native firmware is DDU1APJ2 though

[Galaxy Grand Prime Android Development] Nemirtingas:
I guess that androidboot.simslot can be used to detect if its a dual sim ?

On my phone, the value is 0, but yours is 1
[Galaxy Grand Prime Android Development] pa.thewraith17:
Yeah that should be it. Apparently all stock firmwares support dual sim its just that hardware limitation in some countries. Especially european versions. So what can be done to bring dual sim support to your rom?
[Galaxy Grand Prime Android Development] Nemirtingas:
Update boot.img to enable dual sim support (done) and setup dualsim depending on that value in cmdline and test.
[Galaxy Grand Prime Android Development] Mhmd_Sha:
Plz...update this rom for dual sim user..😭😭😭😭

Please..
[Galaxy Grand Prime Android Development] Nemirtingas:
I'll upload a test dual-sim boot.img.

As I can't test dual-sim, be sure to backup everything you need before flashing the boot.img (especially your boot).

dual-sim test boot.img available on the 1st post.

If anyone tests it, send here the result of thoses cmds just after boot pls:

cat /proc/cmdline

cat /sys/devices/virtual/ssipc_misc/umts_boot0/ssipc_dsds

getprop | grep persist.radio.multisim.config

[Galaxy Grand Prime Android Development] pa.thewraith17:
Want to test it but is the rom rooted? If not do i need to root it with the lineage 13 root package or the g531f root package?

Also there seems to be an issue with gps/location that it crashes the whole system. Hope you look into it :)
[Galaxy Grand Prime Android Development] Nemirtingas:
The gps crashs somewhere but I don't know why.

To root you just have to use SuperSU or Magisk it works fine. No need to use the g531f root package.

[Galaxy Grand Prime Android Development] c3497605:
Hi. Is there a chance this will eventually be fixed or rather unlikely?
[Galaxy Grand Prime Android Development] Nemirtingas:
I would say never until Marvell decides to share their driver sources which they don't want (I already contacted them about that).

Or if someone would like to fully reverse engineer the Hardware Encoder/Decoder and stagefright.

I already reverse engineered the sound, radiofm, partially the camera/graphics driver and thats very time consumming and hard, and it doesn't really worth the work/time spent for this phone.

I was hoping to bring android 7 but unfortunatly without the graphic/hwcomposer sources I couldn't fix the bugs.
[Galaxy Grand Prime Android Development] coincé:
Hello,

does connection sharing exist on this rom? Thank you.
[Galaxy Grand Prime Android Development] fabien976:
"Requirements:

- Flash firmware G531FXXU1APG2 before ! Get an European firmware with this PDA and flash it before flashing this ROM, or your RIL will not work at all."

if you don't use g531f is normal if you have a bug the have been created for this model not another !

thank you to read the first post entirely before complaining about your problem especially if you do not use the right model !

and thank you for being polite with the word "hello" and "thank you" otherwise do not be surprised that we will not answer you

Yes , in the last build after OTA update :)

sincerly
[Galaxy Grand Prime Android Development] rshaw511173@gmail.com:

P.S. Also what's the difference between old audio device and new audio device? What should i flash?
[Galaxy Grand Prime Android Development] coincée:
Hello,

I updated lineageOS and it works pretty well, thanks to you I will be able to keep it for 1 or 2 more years.

Thank you for your work
[Galaxy Grand Prime Android Development] Nemirtingas:
Hope it helps you. You might face GPS bugs, hd videos/ads glitches.

I can't find any entry in the Marvell group to ask someone for the Android Sources unfortunatly.

Rooted version of lollipop with magisk and debloating isn't better if you need a dayly use ?
[Galaxy Grand Prime Android Development] coincée:
Ah, I didn't know Magisk, it's very interesting. In fact, I had to have at least android 6 to continue using this phone because of an important application that no longer supported android lolilop.

As for video playback, gps and camera it doesn't bother me very much, I only use these things once or twice a year, and I bring with me an old backup phone for gps.

On the other hand, if you know techniques to run an android 6 application on lolilop, I'm interested.

thanks you
