[ROM][8.1.0][SM-G531H/BT] Havoc OS for Samsung Galaxy Grand Prime VE 3G

[Alando123]

Havoc-OS is an all new ROM based on LineageOS.
So many features that you probably won't find in any ROM.
Just flash and enjoy...

General:
System-wide Rounded UI
Spectrum support
Razer Phone lock/unlock sounds

We'll not support users and answer questions from users which:

• are running a custom kernel
• have flashed mods
• modified system files
• didn't follow our intructions word by word
• are unfriendly
• And most important: DON'T READ THE OP

BUGS:

• Same as Lineage OS 15.1
  
• Turning on AutoBrightness disables the adjustment of brightness manually, even when turned back off; To fix this, download this app from here and play with the brightness adjustments for about a minute then reboot, you can uninstall the app once brightness adjustment is fixed in statusbar (CONFIRMED FIX)
  Another fix is Settings-> Havoc Settings-> Status bar then enable Brightness Control then in Settings-> Havoc Settings-> Quick Settings change Brightness slider to "Hide" option, then you will be able to slide your finger across the status bar to adjust the brightness. (CONFIRMED FIX)
  
• Changing system font in Settings -> Havoc Settings -> Interface causes bootloop

[NOTE]:

• If you couldn't take screenshots, go to /system/vendor/lib/hw, make a backup of [email protected] somewhere else, then delete it from this folder
• The camera preview will freeze and you can't capture or record after this. To restore original camera function (but will derp screenshot again), restore the backed up [email protected] again to /system/vendor/lib/hw

First time installing Havoc OS to your Galaxy Grand Prime, or coming from another ROM?

• Install latest TWRP Recovery MUST USE VERSION 3.2.2-0 OR ASSERT ERROR OCCURS
• Reboot into Recovery using 3-button-combo (Vol-up+Home+Power)
• Do a Nandroid backup! (Optional and only if you weren't running TouchWiz before)
• WIPE (wipe data/factory reset + wipe cache partition + format /system partition)*
• Install the ROM from sdcard using TWRP Recovery
• Optionally install the Google Apps ( get it here: https://opengapps.org ) (pico GAPPS recommended) (*)

[NOTE]:

• If you're about going to install GAPPS with ROM, install it right after you've installed the ROM, else you have to do a factory reset if you've booted the ROM first

FAQ

Q: ETAs?
A: See here: Link

Q: Anymore models supported?
A: Just SM-G531BT and SM-G531H

Q: Is init.d supported on this ROM?
A: Every LineageOS/CyanogenMod ROMs support init.d, so be free at scriptings

Q: Can you include ABCXYZ feature / Samsung Apps here?
A: NO!

Q: Can I use your ROM as a base for portings?
A: Yes, and mention this thread

Q: Server error in Google Play Store?
A: Install latest Google Play Services manually first (might take long time, due to Lollipop's nature), then you can install apps from GG Play as usual

Q: How to use adoptable storage feature? I see it's new in Marshmallow
A: Go to Settings >> Storage & USB >> Tap on the SD card label (not the eject icon) >> 3 dots menu on the top right >> Settings >> Format as internal and done!

Q: Where's the MTP option? I don't see it in Storage settings
A: This feature has been moved to Developer settings, and will reset to default (Charging) after every reboots. Enable developer options first by tapping 7 times on Build number in About phone section >> Go to Developer settings >> Select USB configuration. The fastest way to do this is plug in your USB with your PC, scroll down notification bar and tap on "USB for Charging"

Q: Where's the "running" section in Apps settings?
A: It has been cut off separately to Memory setting and "Running services" in Developer settings. You can see the memory used by apps for a period of time and closing apps too, but they won't disappear in the menu, and in "Running services", still same as old-fashioned running apps section

Q: Can't install GAPPS or ROM?
A: Install latest TWRP

I have a problem, install Havoc Rom, but it does not recognize my microSD, that is if it appears but when I try to manage nothing appears, I thought it was something of the rom so I changed to the Xenon Rom but I did not recognize it either, before I used one of 32gb now I use a 64 gb one no longer recognizes me, someone knows how to fix it?

Sent from my SM-G531H using XDA Labs
