[Galaxy Grand Duos i9082 Android Development] unclefab:
After weeks of hard work we (Setmov and uncle Fab) proudly present you the first Una ROM for the galaxy Grand I9082, based on 4.1.2 XXAMF7.​

DISCLAIMER​

As usual, your phone your responsability, we won't take any responsability if it flies out of the window or if your girlfriend/boyfriend runs away with it.

PLEASE, DO READ OP COMPLETELY AND CAREFULLY BEFORE ASKING ANY QUESTIONS, ANSWERS TO MOST PROBLEMS ARE THERE

WHAT IS UNA?​

Una is a new concept that takes security to a new level.

Are you tired of seeing so much blatant, outrageous and shameless invasion of your privacy and data mining hidden behind nice sentences like "enhanced use experience" or "complete integration with the system"? We decided to develop secure ROMs where privacy means just that – Private!.

It’s free of charge, we are a non profit structure and we are not here to make big bucks;).

WHAT UNA ISN'T​

UNA isn't a way to help you to stealthily buy massive destruction weapons to foment a coup d'etat in your favorite banana republic or to prepare the third world war:silly:.

UNA secures what leaves from your phone (ie your personnal data doesn't leak and no app can look over your shoulder to spy your activities), but it can't competely secure what comes into your phone.

Why is that?

Because it's just not possible to fully secure a phone from what comes into it, and anyone claiming to be able to do it is either a liar, or an ignorant, or both.

There are too many attacks, some not well documented, if documented at all, and some unknown to the public, and there are too many ways to hack a phone, especially if the user doesn't use his/her common sense.

If you are the type of person that installs apps from shaddy source and/or warez web sites (sites offering cracked paid apps) chances are that at some point you will unknowingly install a malware or a spyware. The same applies if you click on any link, specially on SMS' and emails, if you let any pop out window appear or if you don't protect your lockscreen with a password/pin/pattern and let anyone get physical access to your phone.

A bit of judgment and common sense can save you a lot of trouble, but there's unfortunately nothing UNA can do about it.

Then, if you use your phone to call through GSM your provider will know where you are. If he didn't you wouldn't be able to make any call, the signal has to find you and there's nothing UNA or anyone can do about it.

The only way to prevent that is to disable the phone functions (but then your phone will turn into a wifi only device) and reenable them when needed, head to the scripts section to learn how to do it.

Last but not least, bear in mind that the agencies have armies of tech savvy henchmen and 10 storeys computers, and tricks we can't even imagine, so think twice and use your brain before you attempt to outsmart them...

UNA IS FOR YOU IF:​

. You are willing to learn how to use an unconventional ROM and generally speaking to understand how things work, even if it sometimes requires a little effort to fix this or that little problem (bear in mind that it took us a lot of work to develop Una to where it is now;)),

. You don't mind a few little occasional bugs here and there that come from all the restrictions the ROM contains,

. You want to take back ownership of your phone from google’s claws.

UNA IS NOT FOR YOU IF:​

. All that you care about is the latest gimmick in the latest OS,

. You can't live without the google’s apps,

. You are the kind of person that never reads through the OP and only scroll down to the download section, and then complain that things don't work and/or ask stupid questions in which are answered OP. An example? One guy makes a mod and writes clearly in OP that it's specifically for 4.2.2. Then some people complain: "it doesn't work on 4.4.2"...

If you are that type of person, please do yourself and us both a favour, and close this window now.

ARE WE PARANOID TIN FOIL HATS? OR TERRORISTS? OR CARTEL BOSSES?​

Nope, we only are people that don't see why we shouldn't be in control of our phones. Or why our phones can be wiped remotely, why apps or updates or who knows what can be downloaded and installed without asking for our consent, why SMS' can be sent without us to know, why we should pay for the bandwidth used for data mining and unwanted downloads, and why all those activities should deplete our battery and kill our RAM.

You think we are overreacting here?

You don't have to take our word for it, just download and install Network Log from here:

https://f-droid.org/repository/browse/?fdfilter=network+log&fdid=com.googlecode.networklog

Give it root permission, start logging and open some web pages. Come back to Network Log after a few minutes and see for yourself, you'll be surprised (or maybe horrified?:)) to find out that your android system, your settings, your kernel etc. connect to all sorts of funny IPs, including and foremost google’s.

Now you see what we mean?

It's time to go for Una;)

UNA'S FEATURES​

. Rooted.

. Deodexed.

. Zipaligned.

. Busybox and sqlite installed.

. Init.d support and scripts.

. Auto start disabled for most apps.

. About 120 system apps, 40 framework jars, 30 permissions xmls and 25 libs removed, plus files here and there.

. Very low RAM and CPU consumption, more than 8 hours screen time with the WIFI on, 1% battery decrease every 10-12 hours while in stand by.

. Heavily and extensively modified system, in order to make it secure and prevent it from leaking your data.

. App Settings, Firewall and Xprivacy built-in, and already applied out of the box to make sure you are well protected.

. Xprivacy is a fantastic tool but it has one big limitation, it can't restrict the Android System from accessing your serial numbers and leaking it. For that reason these IDs have been edited as follows:

build.serial (androidboot.serialno) and ro.serialno are both set to "1",

android id is set to "android",

net.hostname is set to "1".

. Wlan serial number set to "00000001" (this number identifies you everytime you connect to the internet, and Xprivacy can't do anything about it).

. USB ID (iSerial) set to 1.

. Unreadable cp access.

. Vulnerabilities patched thanks to Master Key Multi Fix and Fake ID Fix.

. ADB disabled (can be re-enabled, see below).

. By default ADB, all google access (including youtube, blogspot and google search) and the Media Storage are disabled. You can re-enable some or all of them, instructions are in the "HOW TO USE THE ROM" section.

. Plenty of under the hood modifications to make the ROM fast and fluid.

. Multi-purpose navigation keys.

. Call button in contacts.

. Because secure doesn't mean ugly, the whole ROM has been themed with a beautiful green color (if there are enough requests other themes will follow), transparency, and Lollipop HD wallpapers.

. KK style pop-up toasts.

. Multiwindows have been revamped, they are no longer only static in Samsung style but now they can float and be resized too, like on a computer.

. All apps can be opened in floating mode.

. Possibility to choose between different multiwindows layouts in KK's style.

. Heaps of hand picked and carefully scrutinized open source apps.

There are 2 non open source apps (Greenify and Quick Pic) but they are safe, believe me, I have thoroughly examined them. Still, you can always uninstall them if you feel like it.

In time we will develop our own apps, but first we want to see how people respond to the Una concept...

WHY IS THIS ROM 4.1.2 BASED AND NOT 4.2.2?​

Because Samsung did a complete failure with its 4.2.2 version for Galaxy Grand.

High RAM consumption, no floating windows, bugs.

Plus, the newer the android version the more spying there is, despite google's sweet talk about "enhanced user's experience", the infamous Fused Location being a good example.

INSTALLATION​

As usual, make a backup first!

Do backup your contacts and whatever is important because all your apps and data will be erased (your sd card contents won't be deleted though).

Do backup your /system/csc folder, in case you need it for later.

Do backup your efs folder (VERY IMPORTANT).

Open an android terminal from your phone, first type "su" (without the quotes), enter, then type:

busybox dd if=/dev/block/mmcblk0p17 of=/sdcard/efs.img

This will create an efs backup caled efs.img in your sd card.

If you need to restore it type:

busybox dd if=/sdcard/efs.img of=/dev/block/mmcblk0p17

Before you install the ROM, download Philz recovery from here:

http://xdaforums.com/showthread.php?t=2452985

We chose Philz since AFAIK it's the only one that allows you to lock you recovery with a password (highly recommended, if your recovery is not password protected it wouldn't take more than 2 minutes for someone to disable your pattern or pin protected lockscreen and access all your personal data on the phone).

Philz' installation instructions

You need to have Samsung drivers installed.

Boot your phone into download mode (press volume down and power at the same time).

Open Odin 3.07 and connect your phone.

Click on the PDA slot, navigate to where the Philz recovery is located and select it.

DOUBLE CHECK AND MAKE SURE THAT "RE-PARTITION" IS UNTICKED (only "Auto Reboot" and "F.Reset Time" should be selected).

Click start and wait while Odin flashes Philz.

If everything went well your phone will now auto-reboot into the system. Go into recovery, you should see your brand new Philz.

If you are still on stock recovery then repeat the above steps, but this time untick “Auto Reboot” in Odin.

When in recovery, if before you reboot you see a text on the screen displaying “yes – disable flash recovery”, select it to avoid stock recovery overwriting Philz.

Now, download Una from here (scroll down until you get to the download section):

http://unaos.com/

Unzip the ROM and copy it to the backup folder that is inside the clockworkmod folder in your sd card (if there's no backup folder create it by choosing "mkdir" in Ghost Commander).

Boot into recovery.

Go to restore from sdcard, choose 2015-03-23.10.56.05, and go for it!

Once it's done reboot, congratulations, you have installed Una ROM on your phone!

The screenlock password is 23052015​

IMPORTANT!!!​

I haven't tried the latest 4.2.2 ROMs and I don't know if they have Knox or not (the earlier versions hadn't).

If they have it and if you are on such a ROM you'll have to choose custom restore and uncheck boot in the menu, because since the bootloader you have is Knoxed you may get a brick if you downgrade it to a pre-Knox version, don't play with that!

If you choose to proceed, you do so at your own risk, but in any case look first on the internet to find out if it's doable.

If it doesn't work for you then I'm sorry, you are out of luck, shame on you Knox...:(

If it works please report it here so that other people will know, thanks in advance!

HOW TO USE THE ROM​

. Swipe down to access the applications drawer.

. Swipe up to open the notifications.

. Go to settings and set a stong password/pin/pattern protected lockscreen (recommended), default password is 23032015.

. Go in recovery and set a recovery password (recommended).

. Long pressing on the menu key toggles expanded desktop (full screen, no more navigation bar and no more status bar).

. Double pressing the menu key kills and hibernates the current application.

. Long pressing the recent key brings you back to the last application (convenient to switch from one app to another).

. Between the home and the back key there's a supplementary key that can display up to 12 apps (editable in gravity box).

Double pressing that key shows the sound panel, long pressing it shows the reboot menu (note that there's an option to take screenshots in the reboot menu).

. When you open an app you'll see a cascade icon at the top or the bottom right, press it and the app will turn into a floating window like on a computer. Now, open the notifications and check the 4 icons at the top, click any of them and the currently opened floating window (s) will be reorganised according to the layout you chose.

. Go to /system/etc/security/cacerts, check the certificates that are there (you'll find the certificate's name approximately by the middle of the file), and erase the ones you don't need/like.

When you want to transfer files to/from your phone open the USB Mass Storage Enabler app and enable mass storage, that's it. When you are done, don't forget to eject your phone from the computer and to reenable MTP from the app.

. When you install a new application, by default it will be fully restricted in both Xprivacy and the Firewall.

Before you open the newly installed app wait until the Xprivacy icon appears in the status bar, then and only then can you open it.

Most likely the app will crash.

Go to Xprivacy, open its settings and then usage data, you will see what restrictions caused the crash. Re enable some, provided that they are not too invasive.

Many apps require "load.Library" to be allowed in the shell section, that's ok.

Others may need to access the sd card, that's in the storage section and it's ok to allow it for apps that really need to access the storage, like players, cameras or file managers (for other apps try to keep it restricted).

Root apps obviously need "su" and/or 'sh", and sometimes "exec", in the shell section.

Always try to enable as few fields as possible, and bear in mind that data requested by an app is not necessarily needed for that app to work (especially true for identification, internet and mcc/mmc access).

Lastly, give the app internet access in the Firewall if, and only if, it needs it, and restrict some more permissions in App Settings.

If you can't tame the app consider uninstalling it and look for a similar one that has less built-in spyware.

SCRIPTS​

. As said above, by default ADB, all google access (including youtube, blogspot and google search) and the Media Storage are disabled.

If you want to re-enable some or all of them, open the folder on your home screen called "scripts". Click on the desired script and it will be automagically executed.

If you choose to enable/disable google access you ll have to go to the Firewall to reapply its script. Open the firewall, go to settings, choose set custom script, click OK.

. You will see more scripts to disable/enable the Bluetooth, the FM Radio and the Phone.

If you disable the Phone and later want to re-enable it do as follows:

untick App Settings in Xposed's modules section, re-enable Phone, reboot, then enable App Settings again.

. Some scripts will enable you to backup/restore your efs partition and flash a recovery.img (to restore or flash an .img, make sure it's in your internal sd and execute the script).

. Other scripts can enable/disable am and pm, but don't play with it unless you know what you're doing.

. You can uninstall the Wallpaper Chooser and the Media Storage if you want, or keep them disabled and resurrect them when needed.

. If you are very privacy concerned you should consider using the "uncle's phone lite" mod because it enables you to call with only the Phone and the Telephony Provider apps (CSC, Contacts, Contacts Storage, Logs Provider and STK are completely de-activated). That's the method I use to make calls, but you have to know that the dialler forces close after you complete the call (not a big deal in my opinion but still, I may look into it one of these days). You'll find the mod in the add-ons section.

BUGS​

. For some reason the ADW Launcher doesn't allow transparency in the navigation bars while in portrait, I'm working on that.

. You can't download anything from Lightning and Tint Browser, that's because the Download Manager and the Download UI have been uninstalled. If you need to download something, copy the link and paste it in Pale Moon, it has its own download engine.

. Part of the lockscreen and the dialer don't show in landscape mode, it's because the DPI has been modified in order multi layouts floating windows to work.

. All the installed apps work, but other apps you install may crash. I call that kind of apps "google’s henchmen", they only work if the play store services or the bla bla app are installed and of course they won't on Una since all that garbage has been removed.

If I install your app, why do you want to force me to install your boss' app too? Forget about those apps and search Fdroid, you'll find what you need...

. Depending the way you use your phone you may have to fine tune Xprivacy and reenable some permissions, I'm sorry for the inconvenience but it's impossible to set Xprivacy for all users since we all have different ways to use our phone.

ADD-ONS​

. Uncle's themed Sony keyboard, flash it in recovery. It's not open source and that's why it's not included in the rom by default, but it's my every day keyboard because it works fine and because I themed it to make it look nice.

. HD Wallpapers

. Universe Wallpapers

http://unaos.com/addons

If there are many users' requests then I'll upload the following:

. Uncle's phone lite (with clipboard and dialer) for hardcore users. It's safer than using the regular phone configuration, but the dialer forces close when you hang up the call. Flash it in recovery, wipe dalvik-cache, reboot.

. Completely disable internet access for the Android System. Lightning and Tint Browser won't connect anymore since they use the same web engine as the Android System (that is anyway not very safe in 4.2.2), but Pale Moon still works thanks to its build-in web engine. Flash it in recovery, wipe dalvik-cache, reboot.

UPDATES?​

There will be some, but no ETA, you'll have to be patient because now we have to design and release Una for three other phones.

Still, any suggestions/comments/bug reports are welcome, help us to improve Una!

FEATURES REQUEST​

Yeah, sure, we'll see what we can do but we don't promise anything:)

That's all for now, enjoy the ROM!!!
