Facebook app?

I am having problems installing the facebook app. It errors at the play store, and every time I retry, it re-downloads. It consumed quite a bit of my uncle's data cap.

I tried to get myself 2 apks of the app, the latest and version 84.0.0.20.70.

I tried to install it by loading it up in the microsd then installing it there in the phone but it failed

I also tried to use adb install but it also failed with this:

Failure [INSTALL_FAILED_DEXOPT]

The logcat shows some lengthy output which seems to be from the installation.

I can't still post links, at least to pastebin or something.

Any solutions?

In my case, I don't use facebook app on my core 2. Cuz it takes too much space and its freaking slow. I havent tried installing facebook app. But you can use the web browser instead for facebook, thats what I do. I only install Messenger. :)

Really nice work man on developing these ROMs. I only tried the stable one which is the cm12.1 and the cm11. They are freaking awesome ROMs. Unfortunately I gave my core 2 to my mother so basically I don't have the unit. But dont worry man, tbh your cm11 is one good ROM. And is good for daily use. If my core 2 will be back to me, I will test these ROMs. :)

[Samsung Galaxy Core.] Ih24n:

[Samsung Galaxy Core.] LauRoman:
You did not understand my question or i did not phrase the question well enough.

Is there some zip containing only the baseband firmware that i can dirty flash from within twrp to fix it? Is it safe to do that?

Or do i need to flash a stock rom with that version for the phone then flash your custom rom back on again?

In both cases where can i find them?

I'm familiar with flashing ROMs and using separate zip files to flash different stuff, but i usually have done it for more popular devices that are/were supported by the "official" LineageOS/CyanogenMod community. And maybe one device or two that are not on there but are still popular.
[Samsung Galaxy Core.] Samuel2599:
Yes you need to flash a firmware with that version first on your phone and then flash the custom rom on it.

---------- Post added at 20:16 ---------- Previous post was at 20:12 ----------

It did not work, AOB1 fixed absolutely nothing at all. I'm either stuch with a custom rom that has no 3g functionality at all, or a stock rom that has a few bugs of its own.

Installing AOB1 fixed absolutely nothing. 3G worked as long as i had the stock rom installed, but as soon as i rooted and installed the custom rom 3G stopped working.

PS: Acording to TWRP my device's codename is kanas3gxx

Thank you so much [MENTION=6737662]Ih24n[/MENTION], currently testing the new rom. It seems to be a bit faster (in both boot up speed and User Experience) than your previous AICP rom but the resulting logcats are still plagued by gpsd errors even though I'm not using gps.

E/gpsd ( 7642): ASSERT in GlGpsdInterface.cpp:370: Failed to read config file.

F/libc ( 7642): Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 7642 (gpsd)

Plus on boot up, the animation just simply disappears nearly before the boot up finishes giving you a black screen for a while which looks like the system hanged and needed to be rebooted or something but, in reality, it's not. Same thing after installing Gapps, aroma to be exact, I didn't see the "Android is Upgrading" screen, just a black screen.

**edit**

I was wrong that is called "Android is starting...", and yes it does shows up when it's truly needed.

However, the're just minor nuisances, at least for me, and can be ignored like I did on the AICP rom.

That is not what i asked. I wanted to know why the data connection is not working on the rom. I got various answers. From "you should install aob1" to "extract modem.img" from rom. The first one is a stupid answer because i did not want to go back to stock rom and people kept suggesting aob1 like it would somehow fix the rom. If there is no data support in this rom for 355h people shoud say that or get their facts straight before giving a canned answer.

There was no modem.img file in the rom archive file, but some know-it-all kept repeatibg the answer even though he had no clue.

Is there support for data connection in the cm11 rom for the 355h? Are there more versions of the 355h? Does the rom not work with all the 355h phones? No real clear anwer.. just people talking in the wind.
