Added to help one lazy troll researching the answer for him/herself

*

* Only Samsung know exactly what improvements were made in the changelist

Will flashing this ROM wipe my data?

:

* NO it won't wipe your data,

but data wipe is a requirement

in Aroma to ensure a bug free device. Just backup data and nandroid first.

* Installer will auto wipe : system, cache, dalvik-cache & preload

* If updating from a

different

ROM or android build/version, it is a requirement that you follow the installation instructions fully in Post #2 and read the notes below it!

Entropy Lag "Fix"

:

* I created the script sourced from info here

* No need for using Seeder app and less overhead

* To check it's working :

Run android terminal emulator app

su

entro

You should see a figure around 3600 (possibly more), meaning it's working :) Normally 200-300

V6SuperCharger is now Aroma Installer option

:

* THE COMPLETE MEMORY MANAGEMENT FIX ! – by Elite Dev zeppelinrox

[U9RC12T6]Put a V6 SuperCharger +DIE-HARD Launcher in Your Pocket=She'll B Happy 2CU!

>> PLEASE VISIT HIS THREAD ABOVE FOR ANY QUESTIONS <<

THANK HIM FIRST, THEN READ AND SEARCH SECOND, BEFORE POSTING THERE !

* Latest script : V6_SuperCharger_for_Android-Update9_RC12_Test_6.sh

* XXLQG ROM is now 100% SuperCharged

* The V6SuperCharger scripts and other files are cooked into the ROM and will run on boot

* Selecting V6SuperCharger in Aroma will SuperCharge the ROM out-of-the box. There is no need to touch anything !

* Unless,........ you have flashed a custom kernel after ROM installation. This may "break" V6SuperCharger and fail to run properly. Just run the script again that is saved in the Starter Kit found on your internal sdcard. Script Manager will help take care of that.

* Don’t add your own memory or kernel tweaks or PimpMyROM tweaks etc as this will most likely conflict and reduce performance. In any case V6SuperCharger is the only way to go !! (believe me, I'm been constantly tweaking and testing)

* If you wish to modify V6SuperCharger settings to your own, just use script manager and run the scripts that were installed to: mnt/sdcard/ SuperCharger_Starter_Kit. Don’t ask how, but follow the instructions found in zeppelinrox thread or Google for them.

Requirements for effective running

(They are installed together with V6SuperCharger via Aroma Installer, so don't update them) :

* Modded busybox v1.19.4 by and binary BY wraithdu

* Superuser app (SuperSU v0.97 wouldn’t work)

* DO NOT RUN WITH OTHER 3rd PARTY TWEAKS !! Let V6SuperCharger do its thing

* Flashing V6SuperCharger in Aroma will wipe your existing init.d scripts and replace your build.prop tweaks!! Don’t worry, this is all you need

Some info of some installed V6 tweaks

(info sourced from zeppelinrox scripts and thread & scripts) :

Die-Hard Launcher

: [RC9] ULTIMATIC RC6! [EXE]-=Ultimate Jar Power Tools=-With Maximum MultiTasking Mods!

* Reduced home screen re-draws

* Patched services.jar with improved OOM groupings etc

* Max multi-tasking mods

Miscellaneous build.prop tweaks

Screenshots

Languages

:

v4.0.2 XXLQG

*

As released by Samsung

- Post #371

* Will more language support be added? NO, I am not a translator, and only if the newer base released by Samsung natively supports it !

Video & HDMI out

:

* You tell me ;) HDMI out to external display should work

as released by Samsung

* Natively, not all video codecs are compatible through stock video player. You may need to install a codec supported video player app from Google Play. Try without the ARMv7 add-on first

* You also need a Galaxy Tab™ HDTV Adapter + HDMI cable + power supply for the tab + HDMI enabled TV or display

Battery Life & Performance

:

* Give the ROM time to build its caches and “bed in” etc.

* Battery % reporting

may

need to be re-calibrated

1. Use your device to

NEAR

zero % (ie. 2%)

2. Fully recharge

uninterrupted

3. Unplug when 100%

*

Actual

drain really depends on your own configuration, and has

nothing

to do with this ROM.

Some Tips

:

* Lower screen brightness and time-out

* Check apps running in background, unneeded auto-starting apps, auto-sync, GPS, wifi, rogue apps etc

BetterBatteryStats is a good app for checking wakelocks.

* Remove or freeze unwanted System apps (bloatware), disable animations (you will lose CRT off animation until re-enabled), motion etc

Mods & Apps

:

* I have not seen or measured any negative impact to ROM performance or stability on my P6810 model (or reported by P6800 User during test phase), so any potential improvement (no matter how slight), is still an improvement.

* Any in-depth discussion is to be addressed in the respected threads, links are in found in the Credits & OP

AC!D Audio Mods

:

* AC!D Audio Mod "bug" - Selecting sound enhancments from the walkman menu may FC

* May give better sound from speaker or various quality ear/headphones

1. menu/settings/music effects/music effects control panel → select your equalizer, ie Noozxoide (not for walkman)

2. Check the thread HERE for Q&A

3. Your existing equalizer may not be compatible or cause issues. This should be uninstalled before flashing (but the data wipe should have taken care of that!)

AGPS

:

1. Open internet connection

2. Use "GPS Status" app (menu/tools/manage agps state/download) and then wait for first fix.

3. ++ After that, subsequent fixes

should

be much faster ++

4. Try and see how location locks in Maps
