What about /EFS backup and locked boot loader?

I have been an old time user of android starting with sony xperia X3. I had a bad luck with that phone. When sony updated android from 1.6 to 2.2 , the phone went into a boot loop and finally got dead. I sold the battery and screen separately to make some cheap buck!!

After that experience, I have been reading a lot for rooting and there seems to be lot of info on that.

My phone model is Samsung S3 GT-I9300 international version. I am still on the stock Rom with 4.3 on it.

I tried with kingroot app and it bricked the phone and was able to recover with kies.

What I want to know is that, you have mentioned option A, do I need to make any backups (not the contacts and personal stuff which I am not worried when I start playing with the phone) of EFS partition?

Will I be able to restore to old stock ROM just by using ODIN and the firmware which is available from the market?

What I need to know is , will I need any specific data (IMEI or EFS) unique from my phone?
[Galaxy S III General] Warren_Orange:
Hi $@k$h@m

I used Heimdall in Ubuntu and I managed to root and put SuperSU on my phone ! I also put TWRP recovery on as well and then did a backup of my stock ROM. I am now ready for some ROM flashing!

I am unsure whether to go for CM11 or something like Tamasek's CM12.1 ROM. Have you used Tamasek's ROM before? Thinking about it for the first flash I think I will use CM11 snapshot and arter97 kernel. Then I will nandroid backup and then I have a stable ROM/kernel combo to fall back on in the future.

Looking at arter97 kernel can you tell me about f2fs support and how I get it? Does it speed up certain parts of the memory? Is it worth flashing? Also, the kernel mentions touch wake. Is this available for the S3?

Cheers.

I can't believe it I bust my sim slot! I cut my old sim card with a tool cutter and it looked good but it was a little tight going into the slot and I pulled it out and that’s when I must of bent some pins. I'm gutted :crying::crying:

Thankfully a replacement is only £3 and swapping it over looks a doddle :fingers-crossed:

Looks like I will have to wait a week until I can have a proper play. I did download BlissPop ROM and I like it. Been playing around with that all day but Its still not a phone until I get my sim in it.

You live and learn :o
[Galaxy S III General] $@k$h@m:
Hi Mate,

First of all, don't worry at all about the bricking thing, with the option A that i have mentioned, it's 99.99% success, i haven't found a single person yet for whom the method didn't work.

Secondly i would suggest u take the backup of your phone contacts in a vCard format using Kies first so that u don't loose them. And copy all your Personal things on your PC (pics, videos etc).

Thirdly you do not need to make a separate disk partition for the method to work, the CM installed will do it for you. :) Also if u have an International i9300 version u need not do a single thing yourself. Just start the setup and sit back and relax. :) Just follow my method to the letter and you can have a great custom ROM with root access in no time.

MOST Importantly - You can go to stock firmware of samsung but this time you will have to use odin instead of Kies to do that. You won't be able to use Kies once you have installed a custom ROM, but trust me that's a small price to pay for a very efficient ROM.

You do not need to know the IMEI or EFS number though i would suggest u still make a note of it somewhere in case ur phone is lost. Prevention is always better :) Message me if u have any queries. Cheers!
[Galaxy S III General] $@k$h@m:
Hello,

well i have two methods for Verizon Phones, One i have tried myself the other one was tested by one of my friends,

For the First one -

Using Odin Use the Chainfire's Auto Root Application to give root access to your phone. https://autoroot.chainfire.eu/ This application in turn also unlocks the bootloader and hence you can easily install further ROM's. Check the Xda general Samsung forum to learn how to use Odin if u don't know , or just message me :)

Second - This Method requires Root Access on you r Phone. THere's an app on Google Play named "EZ Unlock" to unlock the bootloader , I think this app can help you out but i haven't tried it myself so i can't really comment. But looking at the reviews i would say that this app really works. ----> http://www.mediafire.com/download/qozzz1p43kxzs3z/EZ-Unlock14.apk

Here's a custom Recovery that can help too - http://xdaforums.com/showthread.php?t=2797314

Hi..I did a search but i am completely confused and bewildered by the vast amount of different posts and opinions in threads..so i apologise if this has broken any rules.

Basically i have a stock s3 i9300 (uk) with original samsung jellybean 4.3 rom,I am getting a bit sick of it now (and the bloat) and i am looking to move on to something more appealing..I have already rooted and installed Rom Manager and CWM..i was wondering what the "Best Simplistic dark themed (small footprint) rom" to go for As i want minimal installed size to make the most of my 16gb memory,i dont mind which android version as long as the process is easy and the battery life is among the best available..And of course it is as stable as my current Samsung android rom..

i would really appreciate any valued veteran guidance..many thanks.

$ak$h@m-

Thanks for the info! I looked on a Chainfire thread here on xda to see if others have done what I would be attempting to do with my Verizon S3, but I don't see anyone else saying they've used this method to unlock their bootloader & install roms. By chance, do you know any place on this forum or any others that talk about peoples' successes using this method on a Verizon S3? I'm a little nervous about attempting this method without knowing that lots of other people have done so successfully.... Thanks for your help & your understanding of my feelings on this.

[Galaxy S III General] $@k$h@m:
Hello Mate,

well the method stated above was tried my me on my phone but i don't think anyone else has tried that yet so even i can't be sure of it's 100% success, It worked for me quite nicely but i can't be sure as it's only tested on one phone. Maybe you should try the App method or else Give chainfire a go, as even in worst case scenario your phone would just reject the new recovery and you will return to your stock rom so no worries there. Give it a Go.!
[Galaxy S III General] $@k$h@m:
Hello,

I would say if you don't mind the Android version then go for SlimROM or OmniRom,

SlimROM because it has basically zero Bloat ware and Practically starts with just the 7-8 basic applications. It is also Good for battery life.

OmniROM is not as small as SlimROM but it's more efficient and between the two i would say OmniROM has a very slight better battery Life.

So if you want a really bloat free ROM go for SlimROM and if you want a bit more loaded Rom then go for OmniROM. Both have amazing stability and provide an even better performance than stock ROM. :)

SlimROM - http://xdaforums.com/galaxy-s3/orig-development/rom-slimkat-i9300-t2565166

Many thanks for your reply..i went for slimkat 4.4 in the end and actually found it easier than i had thought,i love it so far but have not yet had time to play properly with it,I was quite disappointed when i realised upon reboot that it did not really slim anything down as my 16gb partion is still taken up with over 4.5gb for the android operating system,,i had followed the correct process for formatting the phone within TWRP..can you advise on this please i really wanted to scrape some of that space back with a "slim" rom..Please advise.

thanks.
[Galaxy S III General] $@k$h@m:
Hello,

So memory is your Primary Aim, First of all it's good that you installed SlimROM, it's the lightest custom rom that i know of. Secondly i would suggest installing Arter97 kernel on your phone as i really helps in memory management, and try to do the following things to increase phone memory:-

Wipe Cache - every day

Wipe Dalvik Cache - every week

Use the Memory management in arter97 kernel if you have installed it already.

The problem is Devices like S3 were built at the time when The requirement of device memory was not too much as most of the devices still had SD Slots in them. I myself use a 32Gb Memory Card to help with the Phone Memory and i would suggest you do the same.

Move the Larger Apps and Music to SD as they don't cause an lag, keep only the important stuff on your Phone. Remember to wipe the Cache every once in a while. :)
[Galaxy S III General] micovwar:
Thanks..i am not familiar with the process of arter97 kernel as i have only just started tinkering so i still have some to learn but i would also appreciate guidance on anything relatively easy to broaden my knowledge base on the subject,,i had held back from flashing a rom out of fear of breaking my device only to be somewhat quite surprised at how easy the process was today (i thought it was a fluke..)..my aim is memory and battery efficiency and i hope to gain both from slimrom i really like it up to this point from my limited use so far,i love it's dark classy feel compared to my lollipop device..i really would have liked to have an easy way to repartition and claw back some of that storage reserved for the android system i cannot compare how big slimrom is meant to be against stock it just looks the same as before,,Any way thanks for taking the time to answer..anything else you could share would be good.

[Galaxy S III General] trey32:
Well, do you know, is there any possibility adding to CM11 - Ambient http://www.androidcentral.com/sites...s/2015/01/Ambient_Display-1.jpg?itok=xonOAUPi notifications? One more question which gapps do you recommend?
[Galaxy S III General] $@k$h@m:
Hello mate

As far as cm11 is concerned I don't think we can add ambient display to it because simply KitKat does not support it. If it's ambient notifications you are looking for I would say go for BlissPop ROM which works on android L and hence supports ambient display and notifications which can be installed from any display mod. It's difficult to add a feature to a device when the OS does not support it.

Even I am shifting to BlissPop for sometime to run a check on the new features on my GS3 with android L.

I'll tell ya if I find something.
[Galaxy S III General] Warren_Orange:
Hi $@k$h@m

I really want to try the audio mod ACID Audio. I have listened to my S3 for a week with Boeffla kernel audio tweaks and I really do not care for the sound that much. It rather aggressive and 'in your face'. The mids are way too forward. I actually hurt my right ear because I have a delicate right ear and tinnitus.

Could you point me in the right direction. I have a nandroid backup of stock BlissRom. Will I be able to flash ACID Audio mod running this? Also, which is the best option? Option 1 [HD Touch AROMA] (ALL IN 1) or option 2 [SIMPLE ZIP]?

Cheers.
[Galaxy S III General] AtomicAngel22:
This is a great thread! It helped me a lot, thanks!

I have just a question about the PurePerformances X Mod, with the Stock CyanogenMod 11.00 should I download and flash the Stock or the CM version of this mod? I tried both, but I don't have any change in the build.prop file
[Galaxy S III General] $@k$h@m:
Hi warren

Yes you can flash ac!d audio engine on blisspop and I would say go with the simple zip

Aroma launcher has a big size and unnecessary items , the zip ensures a clean install. Currently I am using viper audio it works great.
[Galaxy S III General] $@k$h@m:
Hello mate

Cm version works better with the official build and is more stable also the reason there is no change in the build .prop file is because this mod was made for android v4.3 so probably some changes might now show up. Although after installing it I could see a nice increase in battery life so I kept it.
[Galaxy S III General] Warren_Orange:
Cheers for the update.

I've tried simple zip acid audio and I can't tell that much of a difference tbh. I may try V4A tomorrow. Do you think it's a step up on Acid? What is the best way to flash V4A? I've also read it needs busybox installed. Is this correct?

Cheers.

Lollipop

Oky guys so its been 2 months of trying out different android L ROMs on the S3 and by next Sunday I will be able to compile another performance package for. S3 running on android L.(5.0.x and 5.1.x) Look out for it. Also I am listing the ROMs I have tried if I miss any please post it below so that I can test it too. This time i'll include some technical stuff and benchmarks as well so that an easy comparison can be made.

Listing :-

CM 12.0( temasek)

CM 12.1 (Archie)

Nameless ROM

Resurrection ROM

LiquidSmooth Rom

Validus LP 8.0

BlissPop v2 and v4

Dirty Unicorns Rom

SpeedPop ROM

Hazy ROM

Slim Lp Rom
[Galaxy S III General] $@k$h@m:
Hi warren,

All I can say is that Ac!d audio engine made the speakers of the phone do immence hard work if u get my meaning , lately I had been getting rough and jarred sounds from the speakers so I switched to viper4a and it works amazingly. Apart from giving quality music It provides care to the phone speakers so I think it might be beneficial in long term.

Also blisspop officially supports viper so u can install it without busybox but I would still reccomend busybox as without it the engine crashes frequently.

Also for the install , I did a clean install using the zip after clearing the cache and dalvik cache and it worked perfectly for me.
[Galaxy S III General] Warren_Orange:
Hi.

I mainly want it for headphone listening. Will V4A make a difference in that department?

I might flash the last blisspop nightly tomorrow. I am currently running the latest stable 3.2 version. I am tempted by JustArchi's Cm12.1 build 9 ROM. I might flash that instead.

What is your fav ROM at the moment?
[Galaxy S III General] ng1998:
You really should try the latest Archidroid experimental
[Galaxy S III General] Stepman57:
I would replace CM 12.0( temasek) with CM 12.1 (temasek) (that is the ROM I am currently using.)
[Galaxy S III General] $@k$h@m:

[Galaxy S III General] $@k$h@m:

My favorite? well for kitkat it's Cm 11.0

for Android L - Tie b/w Archi's Cm 12.1 and BlissPop v3.4 though i am currently using BlissPop latest nightly, and it has awesome features. PS - Fifa 12 and Asphalt 8 crash on BlissPop
[Galaxy S III General] :
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! :)
[Galaxy S III General] Warren_Orange:
I've heard of two good camera apps. Open Camera and Camera360. Try them both and see if you like them.
[Galaxy S III General] $@k$h@m:
OpenCamera is good also there's Google camera which takes 360 Sphere shots which is really cool
[Galaxy S III General] Beaner:
Fix your links.

You're redirecting us to the AROMA installer page in the launcher part(?).

PurePerformance X is a useless package.

PureGraphics is useless too in my opinion besides it is not compatible with KitKat.

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.

[Galaxy S III General] $@k$h@m:
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 :D (worked fantastic with my old wireless router and dd-wrt so why the hell not? :D ).

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.
[Galaxy S III General] Dreath:
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 :D but, which one would you recommend me?

Someone else's opinion is very welcome, too. :good:

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.
