[ROM][5.1.1_r34][OPTIMIZED/LINARO] OmniROM [10.03.2016]

[ChronoMonochrome]

OmniROM 5.1.1 for the Samsung Galaxy Ace 2 ( GT-I8160 )

-------------------------------------------------------------------------------------------------------------------------------------



This build is based upon the sources provided by Omnirom Team, Team Canjica and nieltg, and has been improved by additional fixes. It's in beta stage, so don't expect some things to be working.
​

Features:

• RIL (phone/SMS/3G)
• Video (playback & recording)
• Audio (playback & recording)
• Wi-fi
• Bluetooth
• Camera (Front and rear)
• 2D/3D HW Acceleration
• USB, MTP, ADB
• all native tethers (Wifi/BT/USB)
• external storage

What doesn't work yet

• video recording

Please note that since build 29.09.15 F2FS and another features of the chrono kernel installer no longer supproted by a ROM one.
To enable them you need to install a standalone version of chrono kernel.
Just install kernel linked below. Note that only R4.2.4 and higher supports OmniROM.


Download

OmniROM

PA GAPPS

PA GAPPS - Pico or nano package is recommended

Rooting

Since Omni ROM doesn't itself include root, you should install it manually.

Installation
Attention! Builds #20 and #21 (08.03.2016) requires data wipe because of SQLite update. Please back up and wipe data if you are coming from older builds to the one of these ones or higher.

Before installation, make sure that you have enough free space on partition /system. AT LEAST 515 Mb is required for build #22 if installing WITHOUT any Gapps. If you don't enough space, follow repartition manual. (at your own responsibility for any kind of possible damage. Be sure to measure twice and cut once!).

• install ROM first
• install gapps
• install root
• install chrono kernel (r4.2.4 or up, latest is recommended)

Misc

Temporary audio fix

For reference only - this is no longer needed since build #3.

Storage swap

For swapping storage edit /ramdisk/fstab manually - change numbers of sdcards or just copy/paste following:

# Android fstab file.
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK
# Data partition must be located at the bottom for supporting device encryption

#<src> <mnt_point> <type> <mnt_flags and options>

Ahh @ChronoMonochrome What more do you bring to us ???
Thanks mate

 

[shoxieJESUS]

Good work, Chrono, as always

 

[str3tch72]

Yeah, Omni is one of my favourite ROM, downloading it right now. Thanks for your contribution!

 

[Oğuzhan1907]

Where is root ?

 

[ChronoMonochrome]

Where is root ?

Added to OP.

 

[str3tch72]

Performance settings working when I applied root.

---------- Post added at 12:26 AM ---------- Previous post was at 12:24 AM ----------

My bad, is always "interactive".

 

[Oğuzhan1907]

I tried rom.I played future game.Good game performance.Very smooth.

---------- Post added at 12:26 AM ---------- Previous post was at 12:24 AM ----------

My bad, is always "interactive".

That actually stupid mistake somewhere in ramdisk - needed permissions are not set for sysfs interface of governor. Following init.d script can be used as temporary fix:

#!/system/bin/sh

chmod 666 /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

UPD. I realized that on this build was messed not only audio recording, but probably it was impossible to make voice call whenever (usual calls, skype etc). I've also added temp. fix to this http://forum.xda-developers.com/showpost.php?p=60720596&postcount=2 . I haven't tested it yet, cause I don't make calls often, but audio recording is working.

 

[exodius48]

Another great rom developed by you @ChronoMonochrome Will you fix offline charging? Its very important for me.

 

[shoxieJESUS]

@ChronoMonochrome
For me home button half-working, e.g. i can roll up app what me need, but i can't open recents apps panel
Edit: My mistake. I forgot to enable custom buttons actions in Buttons settings

 

[monstro78]

Great work. Keep it up.

@ChronoMonochrome you're doing so many for this little device, great. For LPM add this to BoardConfig like gg:
https://github.com/golden-guy/andro...mmit/912ce90471772e19418f5ee1dfa0c84d15a429a5

and you have two ways now, you can use lpmkey + playlpm services from stock JB (and libQmageDecoder.so + battery images from JB).
Remove from /rootdir lpm.rc because is useless now, but add somewhere in /root lpmkey and playlpm (0775) because somehow from system partition cannot be executed, and to init.u8500.rc type something like this:

on charger
write /sys/class/power_supply/battery/batt_lp_charging 1
# Set CPUs speed & governor in LPM, disable one core
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor conservative
write /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor conservative
write /sys/block/mmcblk0/queue/scheduler noop
write /sys/block/mmcblk1/queue/scheduler noop
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 600000
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 200000
write /sys/devices/system/cpu/cpu1/online 0
# Enable DT2W feature
write /sys/module/doubletap2wake/parameters/enable 1
mount ext4 /dev/block/mmcblk0p3 /system wait ro

service playlpm /charger/playlpm
class charger
user root

service lpmkey /charger/lpmkey
class charger
user root

Or use charger binary from CM11 + battery images (res/images to /rootdir) and type:


on charger
write /sys/class/power_supply/battery/batt_lp_charging 1
# Something here if you want

service charger /sbin/charger
class charger
critical

 

[str3tch72]

Mic with calls working good. And yes, this ROM is smoothest ROM I've ever seen. Without hard-tweaked interactive and even on 800mhz, this phone is like a rocket. You're doing really good job for our community, thanks again.

on charger

class charger
critical

Thanks. I already tried to use charger from CM11, but I've missed this and commit for BoardConfig.mk above. I'll try it later.

 

[str3tch72]

One question for you: is it difficult to port or cherry-pick some bugfixes from CM12.1? I'm not hurry, because I'm not using offline charging and location so much.

 

[ChronoMonochrome]

One question for you: is it difficult to port or cherry-pick some bugfixes from CM12.1? I'm not hurry, because I'm not using offline charging and location so much.

As turned out - not very difficult(although first I stuck with some commits that didn't apply cleanly). It's a bit more difficult to find what changes are missing in our repos to make GPS working.

 

[xo.en]

What doesn't work yet
audio and video recording
GPS

Photoshooting works?
Btw, lack of gps is really devastating..;/ Cannot this be fixed with SIMPLE libs copy/paste from cm12.x?

btw, which kernel does it have? last ones were..rather...uninteresting, imho..you know...
