WARNING: INSTALLATION OF ANY CUSTOM ROM [AND EVEN OFFICIAL FIRMWARE USING ODIN/KIES] CAN BE DANGEROUS. DON’T DO ANYTHING IF YOU DO NOT KNOW WHAT YOU DO.
I AM NOT RESPONSIBLE IF YOU TRANSFORM YOUR CODINA INTO A BRICK
You need to have at least official 4.1.2 ROM with temporary CWM recovery (or ANY other 4.1+ custom ROM with recovery) to install this ROM​
Although 4.2 i 4.3 branches of Slim ROMs are considered as not officially developed anymore - device and (especially) kernel sources are still under development - beside of this, i could add some features here and there - so let's call those ROMs as "in development stage". That way the ROMs are recommended only to people with at least some basic knowledge about Android troubleshooting. If your knowledge about Android is enough only to use the basic features of the phone then stay with 2.36 or 4.1.2 ROMs (or any other ROM, whatever. Just don't ask how to enable BLN or development menu for a thousand of times).
Main Features of SlimROMs [may vary depending on Android version]
The Real Dark Slim (TRDS)
SlimPIE
Expanded Desktop
LCD Density Changer
List View & System Animation
Navigation Bar & Ring
Notification Power Widget
Privacy Guard
Profiles
Quick Settings
RAM Bar
Theme Engine
Widgets Viewpager
Performance Settings
For more details go to official SlimROMs site: http://slimroms.net
Main features of used kernels*
Code base updated to Linux 3.0.x+, depending on used sources*.
CPU OC (up to 1250MHz, stability depends on your unit quality)
GPU OC (up to 730MHz, stability is pretty good, but speed bust is debatable)
CPU/GPU undervolting
Many governors and i/o schedulers available
* Probably main releases will be based on default TC kernels, however i consider adding separate kernel zip packages with @ChronoMonochrome's kernel (or maybe even one slightly modified by me)
Other characteristics of my ROMs:
Compiled with SaberMod toolchain
Compiled with optimization level -O3 [mix of "original" SlimSaber optimizations and JustArchi's optimalization commit]
compiled with necessary changes resulted from above changes
Source code:
SlimROMs
SlimSaber
SOURCES OF KERNELS:
Default Kernel by TeamCanjica
Chrono Kernel 3.1
xxxxxx [old, non-OC kernel - maybe later]

- dh.harald - for your contribution in early stage of device sources development;
- ecim.tecul - for OMX patches (cleaning in 10.2 stage);
- jereksel, percy-g2, munjeni - help, support and fixes;

OUTDATED INFO
When i tried to build my own versions of SlimSaber ROMs for Codina - i decided to release it in one thread. Then - i had to decide how "deep" should that project be. Should i stop on 4.3.1 Android version, or move further, to build "complete Slim base"... I took a look into our device sources and found out, that 4.2.2 should be the final border. Our 4.1.2 sources are not good developed as 4.2.2 (which are much less developed than 4.3.1, updated lately thanx to courtesy of @Rox), but good enough (I think).
But what for? We have couple of SlimBean 4.2.2. builds, and probably nobody uses it anyway). Ok, but we have slightly modified device source AND major progress in kernel sources (OC, UV, etc.). Because of it - it was good ground for learning of making ROMs).
And i like number 3 more than number 2).
INFO UPDATE:
ROM based on Android 4.2.2 (planned at the beginning) cancelled [for now?]

JELLYBEAN BUILDS:​
ROM Info
SlimBean, ROM for the Samsung Galaxy Ace II
ROM OS Version: 4.3.1 JellyBean
Sources: SlimRoms (original)
ROM Kernel: Linux 3.0.101, 3.1
ROM Firmware Required: official JellyBean (with CWM recovery) or higher
Recovery: TWRP
Version Information
Status: Experimental
Official ROM version number: Build 2.1
Initial Build Date: 2014-08-25
Initial Build Release Date: 2014-08-27
Current Build Release Date: 2014-08-29
Current Build Number: BUILD II / B8
Inspiration for "creating" this ROM was SlimSaber Reborn by @fusionjack. Some claimed it as most stable/best ROM for Galaxy SII (i9100) phone. Too bad, compiling the ROM for Codina using SlimSaber Reborn sources (manifest) ended with some major issues [System ui silently crashes after receiving statusbar notification]. So, in short words - IT IS NOT SLIMSABER REBORN version for Galaxy Ace II . My ROM uses original SlimROMs sources, but...
1. Modified to work with our phone of course (OMX patches, low in-call workaround implementation, with some apps removed, etc.)
2. Mix of SlimSaber and JustArchi's optimalizations WITH all necessary fixes [build, external/bash]
3. Specific device sources
4. Device specific kernel sources
5. TWRP Recovery taken from KitKat branch
6. Some apps removed (e-mail, exchange, live wallpapers, etc.)
7. Original keyboard switched to Android L Keyboard
8. Things borrowed from SlimSaber Reborn:
Some of memory leak fixes in Settings and frameworks/base sources
SaberMod toolchain sources taken from SSR manifest
Some GPS fixes (may be reverted, because i'm not sure if helps or just the opposite).
Fix for crashing google drive apk [and thx to @PolishVodka]
So, once again - it's not a SlimSaber Reborn exact implementation (but it's close in some parts). I think it's possible, that next releases (if any) could be even more close to SSR, but it never will be "clean SSR", because of apps removed by me and differences in device/kernel sources (which is not the same with differences between both devices). I think next step will be Omni Performance Control integration...
Anyway - there wouldn't be my SlimBean ROM without SlimSaber Reborn...

KITKAT BUILDS:​
ROM Info
SlimSaber Kitkat, ROM for the Samsung Galaxy Ace II
ROM OS Version: 4.4.4 Kitkat
Sources: SlimSaber by fusionjack
ROM Kernel: Linux 3.0.101, 3.1.1
ROM Firmware Required: official JellyBean (with CWM recovery) or higher
Recovery: TWRP
Version Information
Status: Beta
Official ROM version number:
Initial Build Date: 2014-08-21
Initial Build Release Date: ----
Current Build Release Date: 2014-08-31
Current Build Number: BUILD I / B3
----------------
Yes, that build is very close to original SlimSaber KitKat for Galaxy SII (apart from device/kernel differences AND those apps deleted by me). So this time all credits goes to @fusionjack [rest of credits you'll find in his thread]. I made that ROM because... well, i lost confidence in some of our leading ROMs and @shine911 didn't release his SlimKat ROM for long time (last one had serious issues with recovery storages and camera i think). But i wanted to test SlimKat ROM so badly... then i found SlimSaber topics... In the same time some of our fellows claimed that current (or in general) Kitkats are worse than leading 4.3.1 ROMs for our device. Well, i don't think that is so easy, but one is sure - KitKat source update from 4.4.2 -> 4.4.4 wasn't best thing that happened to our device's ROMs. So, first i tried to make our version of SS Reborn, but there was major issue (described above), so i tried to make SlimSaber Kitkat...
Short for now (didn't even tested last builds): It's much more SlimSaber than 4.3.1 version. Actually it uses SlimSaber repository (platform_manifest) with only device specific modification (as said before: omx patches, low in-call workarounds) and maybe some more apps removed. Maybe (just like in 4.3.1 build) i'll change original keyboard to Android L version...
But, in general, it's (or should i say: will be) SlimSaber for Codina).

I prefer cm 10.1 because of flash player and live video streaming. In 4.3.1 they worked?

@up
I tested with Twitch app. It's working. Resolution seems bit low (but i never used that app and don't know if it's normal )

And some more...
--- If you are using xposed, DO NOT POST BUGS! I have already seen people posting issues only to find out it was due to xposed or one of it's modules.
--- When posting bugs, do so with as much information as possible. We can't help you if you don't give the proper information:
* What build are you on?
* Clean or dirty install?
* Default or other dev's custom kernel?
* Are you using a theme?
* If you dirty flashed & have problems, did you try a clean install?
--- If you are having random reboots how about providing a log? These are invaluable as they provide the information to fix a real issue with the rom or to tell me that it is a user error.
--- If you are new to aosp or just don't know much about kernels, it is best to stick with the mainline kernel as it is very stable. No need to mess with the settings either as I have the kernel setup to enjoy out of the box.

Seems interesting my guess is saberslim is slimrom with saber mod? If so cool if I'm wrong sorry but I may have to try 4.4.4 version
When will 4.4.4 version be available

---

Very nice matey, I'm really looking forward SlimSaber 4.4

---

Wow, this rom has potential - status: tweakable(Miryn, check this one(i'll try to make mod from this 1)).
So far i can see:
- cpu control works properly with perfctrl(no 100mhz revert etc.),
- no browser lag with mobile sites present on liquid 4.3.x,
- no "chrono" tearing,
- nice 3d,
- NICE cf-bench score(lowlevel tests) - my main method of measuring "heaviness" of roms,
- fast boot,
- seems to HOLD 2g/3g setting after reboot(liq had problem with this),
To test:
- radio/viper/headphones(liq has issue with these),
- gps,
- cam stability(liq/dirtywriteback issue).
I may even switch from liquid to that one, damn.
You know, i really like ace2...
What puzzles me: why system is generating such big amount of /dropbox logs?

It's slimkat compiled with sabermod toolchain, BUT with many addition from @fusionjack...
Original slimsaber reborn also has many fixes and some things backported from kk

@batlin
"Buttons backlight disabling pack: here"
In JB you can enable custom keys backlight here:
https://github.com/SlimRoms/packages_apps_Settings/blob/jb4.3/res/values/config.xml
(config_show_touchKeyDur>true<)

---

..indeed, it would be nice to have bln on/off in framework somewhere...

---

AFAIK buttons light and bln isn't the same.
@PolishVodka mentioned the buttons backlight...
Bln is managed by NTS (but I never tried it)
And my pack (pack I added) is somehow magical: it turns off backlight and enables notifications
But I'll check that option... Thx

One more thing: SlimSaber KK build (two of them actually) is ready for couple of days but I don't have time to test it (4.3.1 is working good)
