Hello! Thank you for this usefull guide for my S3.
I have only 2 questions:
1. Do you recommend the Last nightly builds for cm11? And have i flash them every week?
2. Can you recommend a good camera app, or the stock cm camera is enough good? Can i use HDR with it?
Thank you for your answers!

Thank you for your answers!
I've heard of two good camera apps. Open Camera and Camera360. Try them both and see if you like them.
Sorry if this question is not allowed on xda..
Can you guys please say me which 5.1 ROM gives the best battery life..?

hey ^^
can you please delete the links to Pure Performance and Pure graphics and also delete infos about those things? Those two scripts/tools are a hoax and don't work properly (read the last pages on Pure Performance). In worst case they will brick your device. They are only a Placebo and don't improve Performance. They were copy pasted from other people without proper credit and are very old. I hope you understand that. I do this so people don't use useless tools that in worst case can screw up everything on your phone.

Hey Mate,
Sorry for the Links, i'll update them for sure, and also i am not recommending pure-performance and graphics for Android L users it's best for Cm11 and it works nicely for me. I sure got a boost in battery and a better color contrast and depth. Still Even without these mods CM 11 it a great ROM

Thanks!
I just wanted to say THANK YOU for making this thread "noob rooter friendly" and explaining in few simple steps how and what to get.
I have been using I9300 for 3 years and was about to throw it out because the original Samsung bloat was just getting way too slow... so I did what I usually do with "old things" - try put a new linux on them (worked fantastic with my old wireless router and dd-wrt so why the hell not? ).
I'm not a gamer and mostly use my phone for mail/camera and audiobooks... now I can actually use facebook without that horrid lag it used to had.
I have not went further than CM11, just wanted a device that does not take 3 seconds to respond to a tap on app or wait 10 seconds before opening camera... and looks like this did it.
Compared to original Samsung rom on JellyBean this one is WAY faster and looks like eats less RAM - I barely had 150 megs free with stock and nothing running in background
So far there have been only minor quirks (camera stopped responding, something unnoticable crashed during night) but hey, I was prepared to shell out $$$ for a new phone.
On a final note - if you are looking for a way to try speed things up on your old sammyG, this might be it. This is how it looks today: zarrseo.com/sammyg.png - sorry, just registered so can't attach image to a post.

Remove Root On Cm11
I used the CM installer app to install CM11 on my GT I9300.
Everything is working great.
I have a problem with my internet banking apps in that they won't allow a rooted phone to conect.
Do you know if there is a way of unrooting but keeping CM11?
I definately don't want to go back to the buggy 4.3 Samsung firmware.

Hi, I tried to install this and I could never get acid to work, it just kept crashing my phone when it turned on. After 10 or more flashes trying to figure out how to fix the damn thing I gave up and only have arter97's kernel and cm11 on my phone but it is acting really wierd. Android ui and whatever process seems to crash a lot for whatever reason, the performance is really bad and it doesn't seem to display the battery percentage right (sometimes when it's at 20% the screen shows wierd colors and it turns off, then I plug in the charger and it says that the battery is at 0%) and the drainage is huge.
I made a backup before doing anything to my phone but I don't know if it will restore my kernel to it's default, but still, I don't really want to go to the default ****ty android, if anyone could help me get everything running nice I would be very thankful. Also I would like to know if I have to flash the kernel everytime I do the full wipe before installing a rom.

Your suggestion
Hey buddy,
As you have tried many different ROM's, I'd like to know your suggestion for me to flash my device. I'm not so motivated to flash my phone that often, so I need something for the next 4-6 months. I'm looking for something in an advanced development stage, which is stable and has a great battery life and performance. Maybe I'm asking too much but, which one would you recommend me?
Someone else's opinion is very welcome, too. :good:

The S5 Sensation v11 is the best ROM which I tested in my S3.
http://xdaforums.com/galaxy-s3/development/rom-s5-sensation-rom-v3-1-t2759425
It's still based on KitKat though. But the question was for stability_and_ advanced development. I don't think there is a stable 5.x build for S3, so S5 sensation may be a good choice.

Why do you still keep these links in OP ? Seems that this "impovements" are fakes and it needs to take time to find it. Is it a kind of test for your followers ?
. I admit, it's wise not to follow everything without checking but was it your intention ?
I'll Update those Links with new mods asap, i am getting a lot of problems with these mods and they are getting way old. I have been Testing for over a year now and have compiled quite a list of ROMS, and Mods, Will hear from me before christmasHi!

22So, I have been using an S3 {yeah S3 , i know old, but duh i just love it } for over 3 years now . I started out as a complete noob, still am, and S3 was the first phone that i started working on. Over the years i have tried many custom ROM's , Kernel's and MOD's and i have tried here to create a List of Best Performing Custom Items over the course of 1 year, with special care for people like me who have just started out in the world of android, So here goes. {in 4 steps} :-
<1> Best "FAIL-SAFE" Method of Rooting/Installing a custom ROM - I know most of the people are afraid of bricking their device's, the first time they root. I have been in that situation and had my phone soft bricked many times while trying out different thing's. So the Most FAIL-SAFE Method that i have come up with is this:-
Many people suggest rooting the devices first and then installing a custom ROM. I have tried to do things a little differently so that the first timers can get comfortable.
A. First thing to do is install CyanogenMod on your specific devices. [without rooting] , The developers at cyanogen have made an application to directly install Cyanogen to your devices from your PC like a regular Software Install. The Link and the Instructions can be found on the official Website - http://get.cm. The process is very simple and easy to do and after the install your device gets automatic root access. The xda thread - http://http://xdaforums.com/android/apps-games/app-cm-app-installer-t2959922 - {you get CM - 11 from this download }
B. Now that your device is has CyanogenMod, you get a rooted device and a custom ROM. But the problem with Cyanogen is that the Custom recovery which it provides has very limited options available. So the next step is to go to Google Play Store and download "TWRP Manager" or "ROM Manager" [i personally use TWRP]. This application will help you to Install the TWRP or CWM recoveries on your Phone. The process is fairly simple, After Installing the App, Choose your Device Model and Version and Let the app do the rest of the work. PS the apps require ROOT access which your phone can provide now.
C. By now if all the steps are performed correctly [very less chance of something going wrong because most of the tings are done automatically] your respective device should have a custom Recovery installed. Next and Most important step is to Create a NANDROID BACKUP [basically an ultimate backup to restore everything]. Go to recovery mode [Home+Volume up + Power button] and select backup, and make a complete backup on your SD card. It's really important to create a Backup before doing anything. This step must not be skipped in any case.
D. Now it's time to let your imagination run wild xD, Download custom ROM's, Kernel's MOD's etc and just copy the zip's to the SD card and install them using the recovery. In case anything goes wrong Just restore from the Backup you made earlier.
[PS: Update your backup's regularly]
<2> Now's the list of My Personal Favorite's which Have Improve the overall Performance of My Phone Greatly. All the ROM's, Kernel's etc have been personally tested by me for over 3 month's for Issues related to Stability, Performance and Bug's . I have tried to put forward the Best package for optimal performance.
1. Recovery [doesn't affect much] - - TWRP Recovery: Personally "Team Win Recovery Project (TWRP)" is my favorite because of it's easy to use touch control's , it's efficiency and Design. I like the cool blue texture theme of TWRP and the speed with which it create's backup and install's new things. The performance of the Phone does no depend upon the Recovery though and you may choose whichever recovery you are comfortable with.
2. ROM - BlissPOP v4.0.3 (CM 12.1 base) : Yes i have chosen this ROM out of the many other i tried. The reasons are very simple, This ROM provides outstanding stability and Performance to the device. There is no bloatware in the ROM and there are simply hundred's of features available for customization. It's compatible with generally all the Kernel's and Mods available for your device and the regular Nightlie's are an added bonus. It's the only ROM based on Lollipop(5.1.1) in which i haven't found any Bug's or stability issues.
Many people told me to try Paranoid ROM but personally i find Paranoid a little buggy, and i found that the PI controls and Halo, due to which the ROM is popular are not of any important use to people like us. They only add a touch of appearance to the device [strictly my view and i mean no offence to any other person ].

6. Root Applications -
A. Titanium Backup:
You can backup, restore, freeze (with Pro) your apps + data + Market links. This includes all protected apps & system apps, plus external data on your SD card. You can do 0-click batch & scheduled backups. Backups will operate without closing any apps (with Pro). You can move any app (or app data) to/from the SD card. Available on Google Play
B. AdAway for Android [built-in app in BlissPop ROM]:
to block ads on your Android device this app is not avalibale on the playstore but you can still install it from this link
C. Greenify:
Is a good application to make your Android device more faster, by hibernating the background apps that you don't use. this application is completely free. Available on Google Play
These are the only Apps which i find useful in the long run as i have to use them constantly. Rest application's are used from time to time but not regularly. So this is My List, i'd be glad if anyone want's to add to it ^.^
I'd Like to Thanks the Amazing People who have Made the above Programs to make our Phone More performance and Appearance efficient. ------> CyanogenMod community, BlissPOP community, xda developers, Jeeko, JustArchie, amarullz, the Ac!d Audio Engine Team,zhuhang(Viper Mod), TWRP team.

Intense Testing Period -> Over 8 months [tried the new Lollipop ROMS's , over 20 kernels, Latest Android M ROM's , some personal opinions
================================================================================================================
Firstly sorry, for the delayed updates, i have been a little busy trying to develop my own ROM (surprise! surprise!, not for S3 unfortunately thought as i can never come close to the current ROM wiz's ), now in the second edition , I have tried to utilize my knowledge over 8 months to put up a new more enhanced guide and have also put up common and uncommon bugs which I experienced along the way and have provider the working solutions for them. Also I am extremely sorry for all those broken links and not working Mods, i'll try to keep my list precise, sharp and accurate this time.
1. Alternate method to Root (super easy, risk free, takes at maximum 5 minutes) - {for windows running PC, stock ROM or any other custom ROM can be used}
So, I would still recommend using my method 1 in order to initially root your device, install a custom ROM and a Recovery as i know the fear and anxiety or every new user trying to root his phone for the first time.
Now for a little more experienced users (quickie guide) [for I9300 version] who do not want to spend a lifetime to just get their devices rooted -
(a) Download the Chainfire's AutoRoot file here and place this file on your PC.
(b) Download Odin (latest version) on your PC here and unzip the file and start odin.
(c) Power down the device, then reboot in Download Mode [ press Power button + Home Button + Volume Down Key] and press volume up key at the caution screen. (little Hint: mostly the device reboots itself when you do not press the 3 buttons at the same time, to counter this press the volume up button and the home button first and hold them and then press the power button until you see the Galaxy S3 logo)
(d) Now connect your device to your PC using a sturdy USB cable. After doing this 2 outcomes are possible:-
~1. Your device is identified by Odin and a faint blue colour is shown on one of the top tabs indicating the port through which your device is connected. In this case proceed to step (e).
~2. If your device is not recognized by odin ie no blue colour, then the drivers of your device might not be installed on your PC. To tackle this download the Driver Suite from Samsung here and run the program. If done correctly when you next connect your device the drivers should get installed and odin should recognize your device.
(e) Click the "AP" button on odin and select the "Chainfire's v-xxx .mad5.tar " file which you downloaded above, odin will then take some time to check the file and when it's ready press start. CAUTION - do not change Odin's settings and assure that Reset Runtime and Auto Reboot are selected, never select re-partition on the odin interface.
(f) After the installation is complete your device should reboot automatically and you should have SuperSU installed (indiacting 99.99% times that your device rooted successfully ).
(g) If you want you can then install a custom recovery using the method indicated in my "method 1" [above].
-feel free to message me for any doubts-
Here are some of my new recommendations based on personal experiences:-
2. ROM's - I will try to divide this section based on firstly Android System and then further based on Stability, Features, Performance. Further i will be adding 2 ROM's for Android M . [i will not be naming ROMS which have a touchWiz interface]
(A) Android Lollipop and Below
Stability - Official CyanogenMOD 11.x [kitkat 4.1.1] - Zero Doubt, this one is the most stable thing out there for S3, old, yes but well you can do anything you want with this ROM and it will not seriously bug out on you when you need it. If someone does not mind going for an older version of android and needs epic stability, just go for it.
Features - BlissPop v3.0.x [CM 12.1 base][ Lollipop 5.1.1] - This ROM is filled with features, you name it, this ROM has it, PI controls, Built-in apps including AdAway, Kernel Modifier, Greenify, SuperSU etc, seamlessly integrated into the build environment. Each and every feature of this ROM is customizable, every font, colour and animation. Simply put, for someone who needs features and customizations go for this one. On the other hand, this ROM is less stable (crashes quite often ) and provides a slightly laggy gaming experience. No bloatwares in this ROM.
Performance - ArchiDroid [CM12.1 base][Lollipop 5.1.1] - Performance, Performance and more performance, all the technical aspects of your device will be enhanced and although the customization features are minimal but this ROM turns your device into a Performance Beast. All the gamers and performance lovers, what are you waiting for
Android 6.x.y Marshmallow
1. RESSURRECTION REMIX M - Fast, Durable, Amazing performance. Fell in love with this one when i used it, and this is my current ROM, no bugs so far and have been using it for over 1 month. Immensely Customizable, no lag during gaming, an amazing upgrade from Lollipop.
2. NamelessROM 3.0 - Feature Loaded, Minimal, good Looks and customization features and of course the ever caring support team of Nameless makes this a go to ROM.
>>> A bit more studying will be required before i finally divide the Android M ROMS's based on their features, performance and stability. Will be posting the results as soon as i am finished.
3. Kernels - AGNi pureCM and Boeffla-Kernel (26-03-2016) , tied, tested and proved that they are the best on very benchmark or performance test, although battery usage is better balanced on AGNi whereas Boeffla is more inclined towards performance.
You can find the Links to all the above ROM's and Kernels and many more in this thread - here
PS - Please Post your bugs in the thread and i will do my best to try and solve them out with an easy and sure solution
Cheers!3As a user of S3 for over 4 years, which is still my primary phone with no complaints, if you are not concerned about android version, then the best option will be ArchiDroid V1.7.18 based on stock 4.3 (My personal opinion).
http://xdaforums.com/galaxy-s3/development/rom-archidroid-v1-7-16-power-hands-t2228171
I have tried a lot of popular custom ROMs including Cyanogen, Archidroid's Lollipop, 4.4.4 Ports from I9305... and found problems like bugs, poor camera performance, stability issues, heating and battery drain.
Few things to note while using this ROM:
1) Use stock app for minimum requirements (camera essential). Do not install bloatware.
2) Use Nova launcher
3) Use external apps for Dialer, Contacts (True Phone), Messaging (Google messenger/Textra) and Gallery (Quickpic)
You will have the best performance and stability from your S3 then. It makes a perfect compromise between everything. Ultimate daily driver. You will never have the excitement of new android versions/new apps which supports newer android versions, but will have a rock solid "Phone" for primary use.1Hi warren
Yes I have used slimrom too on the s3. Its good but as u are looking for stability I would suggest go for cyanogen because in my experience cyanogen shells out a better performance as compared to slimrom. My gaming experience was a little reduced in slimrom and I experienced a little lag but no such issue in cyanogen.
Secondly if you use ubunto I would suggest going for a virtual box to install windows and then the cyanogen application as it's the safest way to install a ROM.
U have to got to " get.cm " from both your phone and PC
On PC a windows installerbwoll be downloaded and on the phone an APK will be downloaded first install the apk the install the windows program and then continue as given in the installer setup.
Else mate, I wud say first download the stock ROM of s3 as a backup and the continue to root in the traditional way .
Any problem just ask me
Cheers1
Hello Warren,
Good to hear that you are having fun with your new phone.
Firstly yes i have used Tamasek's/JustArchie's CM12.1 ROM and it's quite good to be honest. So first i'll talk about it then i'll come to the kernel.
So 12.1 yes, the most noticeable change android L 5.1, all good, nice appearance, but i would say just think again for a bit.
A comparison between the two is a mammoth task but i'll try to brief it for you and tell you why i like the CM11 better even though it has android KK. It's upto to you though what you choose to flash. i even have a nice tip for you in the end
So first let's see the CM12.1 -
Quite stable, i used it for like a month or so for testing and got a good result. The performance was at par with the rest of the ROM available for S3. The Graphics, Audio and Processing quality is also good and is suitable for light use. Here's the catch though, Firstly the Gaaps, many gaaps available Android L are not compatible with the unofficial 12.1 so u'll have to look around to find the correct set of Gaaps.
Secondly i personally find that the CM 11 has a much neat finish as compared to CM 12.1, i don't really care about the android version as for me if i can have all the features of android L in a more stable KitKat ROM i don't usually upgrade my ROM. THe reasons are very simple
Firstly it's Unofficial, No Nightlies, rare updates. Also the unofficial ROM is alive only till the Developer is still working on it. Once he stops his work it's a very slim chance that you can get your bugs fixed.
As for the Official one, there are thousands of forums on Solutions to various Bugs and Numerous customization options. We can't really know whether the unofficial 12.1 supports all the things available for the official ROM.
Based on Performance both the ROMS perform equally, there's a camera Bug in the 12.1 which can be a problem sometimes but rest is all good.
On a personal side [not really of importance] i like the Calculator of the CM 11 better than CM 12.1.
Now the Kernel - arter97 is simply amazing, The most noticeable changes are - 1800 GHz overclocking [yeah from 1400 to 1800 BOOM!],
the Knock feature - Tap the screen to unlock the phone, no need to use any buttons, Battery Tweaks etc.
Also it used a custom engine to allocate the Files to various partitions to the memory so yeah it saves space plus we can even Increase our RAM a bit by using the Internal Memory of the Phone.
I am a Hardcore Gamer and use my phone to the limit sometimes [ Playing Asphalt 8, Real Racing, GTA: San-Andreas, FIFA 15 and WWE Immortals can take it's toll on the phone.] these games require very high end phones but with this kernel they all run liquid smooth on my phone without even a slightest bit of lag. So yeah i would surely recommend arter97's Kernel. PLUS u get Boeffla Audio Engine which is an added BOnuS
Touch WIZ -- Not Necessary, I flashed it using TWRP and it worked Just fine.
f2f - f2f has better memory allotments and it's pre configured, we usually don't have to enable it, it's much better than extD though.
TIP - arter97 supports dual Booting so you can even enjoy cm12.1 and cm 11 at the same tine [Dual Booting i'll cover in the next post if you have a problem doing it ]
-----> Also U can use the Siyah Kernal, which work's just fine and even has an amazing Boot Image but now as much features as arter's.1
Firstly Thanks for asking this, i wanted to pick up the problem of FM radio for a long time for our devices, actually as you all know the thing with FM, just like WIFI and Bluetooth, is that it requires both hardware and software, now our devices come pre equipped with the hardware, so we need just the app for running it, and fortunately we now have one, honestly guys, i am really sorry, i have actually know about this app for a long time, just that the question of fm radio had never been raised by anyone so i assumed people already knew about this, so anyhow, all you need is the following app, and root access, and you can access fm radio <the actual fm radio , not the internet one> on any ROM. It comes in both Paid and free version and is available on Play Store as well as on XDA. The app is called Spirit FM, and i have tested it for ver a year now and it works well on all ROM's and on all versions of Android, i am currently using the paid version Spirit 2 compatible with the Cyanogen and other AOSP ROM's.
Link HERE
Now to CubanLegend,
As your FM Radio problem is probably solved by the above app, i'd suggest not double booting your phone, as the 827mb of RAM available on the GS3 can have serious issues while handling 2 ROM's. The memory management will be disturbed the storage space will be clogged. I have tried it with RR[MM] and BlissPoP, with arter kernel's dual boot and actually did not like the results, lags were common and device crash and heating were often.
