[Q] Is a Custom Rom necessary after rooting - Galaxy S III Q&A, Help & Troubleshooting

Hi All,
I tried looking but did not get any concrete answers so, Just wanted to know if custom ROMs are necessary after rooting an S3.
I ask this as I have blown up few of my earlier phones(SG S1 and MMX A110) after various combinations of installing and removing different ROMs, Kernels etc.
So now I was hoping to find out if i just root my S3, will it function as it is now. will the stock ROM still be there, or will i have to download and install the stock ROM zip from somewhere?
I want thinking of rooting this mobile as i need USB mass storage, bloatware removal and a few RAM mgmt tools that i generally have used.
please suggest your views on this topic.

(1) all is answered in the guides if you understand the process of rooting
(2) for you explained: rooting does not delete anything, it just gives you more access, hence your stock rom will still be there, meaning you can root a stock rom and keep it or change to a custom one

This will definitely help http://forum.xda-developers.com/showthread.php?t=2362743

Questions about custom ROMs, rooting, and operating systems.

Hello all. I'm about to bombard you with a few noob questions that I'm really hoping someone could help me out with.
I'm currently using a Galaxy S2, but after reading a bit about custom ROMs and the ability to possibly increase battery life among other features, I have decided to delve a bit deeper. I do have a few questions though.
- What is the difference between rooting and using a custom ROM?
- Do I need a specific Kernel version or build number in order to use a custom ROM on my Galaxy s2 or does none of that matter when installing a new ROM?
- It is to my understanding that custom ROMs cannot use Kies. So, in the event that Android 4.0 comes out, will I have any problems being able to get it onto my phone with a custom ROM? Will it cause any interferences between the ROM and the new operating system?
I'm very interested in trying this out, however with the firmware I am currently running, there is no replacement to be found. In the event that I want to revert back to factory, it probably will not be possible to find this specific firmware that I am using (already searched).
Thanks a ton in advance for the help
Rooting gives you access to aspects and features on the phone that you otherwise couldn't get to. Installing a custom ROM wipes out the software on your phone and replaces it with software someone other than the OEMs developed.
You need to unlock your bootloader in order to install a custom ROM, and the process for this differs from phone to phone. Other than the different steps, it doesn't really matter what your phone has to start out with.
I don't know anything about Kies.
Honestly, I would highly recommend rooting your phone... just make sure you maek a backup as soon as you get root access (but before you install a custom ROM) and you're good to go!

There's probably a for for the GS2, where you can find details for your phone. Some methods of rooting on some devices do require a specific version of firmware. Give or take carrier issues I heard the GS2's were getting ICS in an update...
The main reasons to root your phone are to do things you can't do without root. For example using a VNC server you typically requires root, but it allows connecting to your phone via VNC. Custom ROMs are usually rooted; installing a custom ROM doesn't always need root (e.g. nvflash) but it helps eventually.
No idea what Kies is and I'm to cold to Google it. If it's in the market, check it in a browser to see what versions they support.

[Q] Need help with 10 questions... Getting started...

Hello All,
After 5 years of programming, hacking, and cracking iOS and iPhones i decided it was time to quit and start fresh, I got myself the Samsung Galaxy S3 4g i9305 / Telstra
I am new to this entire Android scene, therefore I have several question to ask... your help will be greatly appreciated.
1) I would like to try and remove the preinstalled carrier (Telstra - AUS) ROM and install a stock 4.1.1 Jelly Bean ROM (without any adds or added crap) – How can I go about doing this?
2) Can I back up my current factory ROM so I can restore it if something goes wrong or I change ROMS?
3) How can I root and unroot the device?
4) Are there any precautions I need to take? Are there any irreversible changes that can occur? The main question is; can I always return to factory stock ROM (from the factory), settings ect if something goes wrong?
5) What are Android equivalent to Cydia or Installous?
6) Benefits of rooting the device?
7) Similar Apps to ‘Get Apk’?
8) Best sources for themes, apps, hacks, ect? Maybe a usenet thread?
9) Any interesting tips, guides, sites to help me get a full grasp of the entire Android system?
10) Best ROM available for the s3 4g?
I am sure some of these questions might have been previously covered elsewhere, I have searched for answers but I am still uncertain on several aspects.
thanks you, and I look forward to your feedback.

*******DON`T install KIES. If your Rooting and flashing your phone, you won`t need it, and it could potentially get in your way******
The simplest way to get you started is to .....
1. Install Samsung USB Drivers on your PC - http://www.samsung.com/uk/support/model/GT-I9100RWAXEU-downloads# (works on all Samsung Devices)
2. Download ODIN (http://forum.xda-developers.com/attachment.php?attachmentid=1432843&d=1351270936 - self contained Executable, run it "as is")
Download this (Unbranded UK Official Stock ROM - should work OK) (http://www.hotfile.com/dl/177306141/248b29e/I9300XXDLJ4_I9300OXADLJ4_BTU.zip.html)
Go to this page http://forum.xda-developers.com/showthread.php?t=1671969 For an excellent guide how to flash your ROM using ODIN
Now go here http://forum.xda-developers.com/showthread.php?t=1957273 - Excellent Clockworkmod (CWM) recovery flashing guide
You should now have a rooted phone, with The latest official 4.1.1 JB, and a custom recovery flashed. Hope this helps..
If my phone has carrier specific rom, in my case Telstra, do i have to find another telstra? there is another guide here that uses the Optus rom (another Australian carrier) in this case Optus, can i use that one?
[GT-I9305] Australian Samsung Galaxy SIII 4G Root Guide - NOT for other variants
Is the process to unroot the device difficult? will something changeonce it is rooted?
I also noticed that once i get the phone into download mode, the seccond i press the continue button it goes straight into Downloading... Do not turn off target, and i cannot do anything other than hold the power button to reset...
Last issue i am facing, i have read many threads about this same issue, (it may be specific to Australian updates only) i cannot change,move, add, or remove any of the home screen (not lock) dock icons.. and yes i have tried every method but it may be very well something to do with the australian models as others have reported this problem and yet there is no fix for it... - so if i flash the rom will that fix the issue?

Please be aware that 9305 can have a different network circuit that the normal i9300 - read carefully the subforum for 9305!
Also you really need to start looking around - there is no magic tutorial, there are just a HUGE amount of separate posts (and with 9305 you need to be extra careful since there ARE small differences).

[Q] Help rooting and installing rom Huawei y300

Hello there, how are you?
My problem is, I received an Y300 as a gift, haven't yet received it but I want to prepare the necessary things to root it and install custom roms on it. No, this isn't the first phone I install a custom rom to, as I have already played with an Optimus L5 of a friend. Could you please answer this questions?
a) How do I root the phone and install CWM or other recovery? I have found many tutorials but they are confusing, and require waiting for 2-3 days for the code to unlock the bootloader. In case you need to know, it probably is the normal Y300, the international one, so no Asian Model
b) How many ROMS are there for this phone? I like Cyanogenmod and stock roms the most, I can barely stand the stock rom in the phone, so I would like to install a new ROM on it ASAP.
c) By flashing the new ROM, do I lose IMEI or something like that (EFS Folder in Samsung phones)? If so, how can I back it up?
Thanks for your help

Here is a GUIDE to unlock the bootloader and root your phone
Thanks, LS.xD
This was all I needed, I've found a CM11 Rom in the Modaco forums, hope it works well. Just got to wait until I get the phone
Okay, so I downloaded the latest nighly of the ROM, but it appears that CM11 is not very stable and has many problems with SystemUI (statusbar) and other things. Aren't there any ROMS for the Y300 on XDA? Also, will I lose my network connectivity if I do the wipes (data,cache, dalvik cache)?
Again, thanks for all your help, I appreciate it
EDIT: Found CM10.1 here in XDA but it redirected me to Modaco, however it is quite stable, downloading now. So which wipes do I have to do, in order to get everything smooth? Also, as I said will I lose my network connectivity or IMEI if I do these wipes, or I can do this without worrying

What Would You Choose??? Custom ROM or Privilege of root access with Stock ROM.

Hi All,
This thread might not be interesting to many "Geeks", who are aware of flashing custom ROM, Unlocking Bootloader, Get root access of your android device, Android Development and many more.
But your response might help few newbies who are still have no clue about these terms but wanted to do some techie stuffs wit their Android device.
Which is the best option you would prefer to ?? Newly rolled out fresh latest custom ROM on your device or Stick to same old kernel, baseband, ROM and wanted to play safely with rooted device.
P.S:- You can share the threads of discussion which are already shared so that this topic could bring an over all idea/benefits/Dos & Dont's of custom ROMs and Rooted devices .:good:

Root My Galaxy A5 (2015)

Hello Guys,
I am new To XDA and recently registered. So I am not sure that I am writing this thread in right place or not. So, please tell me the right place if i am wrong.
Ok, I have Samsung Galaxy A5 (2014)/(2015) (SM-A500G). It came with Android 5.0.2 Lollipop.
As most of you know that few months earlier samsung rolled out the marshmallow upgrade (6.0.1).
I upgraded but my device performance considerably reduces. Even some daily used to tasks start giving too much load to the device. In small words, Device started to hang too many times than earlier.
And some of you may suggest the reasons like:- Nearly complete storage, Power Saving, Too much apps, Virus and malware etc.
(Samsung Help Center Suggested it). But i can assure you this is not the reason. My storage is almost 70% free. etc etc.
The real reason is MARSHMALLOW UPGRADE.
So, I think the best way to solve it is Rooting.
But I am an newbie to the world of rooting. I don't know what is custom recovery, TWRP, Odin, CF-Autoroot etc.
I only heard there names but nothing else.
This doesn't mean that I know nothing about how android works and what is custom ROMs. I can manage these things; but not the above mentioned.
So please anyone of you can tell a detailed guide how to root galaxy A5 (2014) on marshmallow 6.0.1 with all the steps mentioned
and what each steps do. It will be very helpful.
And few things more, 1] I am thinking that after rooting I reinstall the official Marshmallow ROM; as earlier I updated my phone by OTA update and so might it cannot get to it's full potential. I am not sure that this method will work or not, so please clarify this point also.
2] My only source of Internet Connection is the device itself by making hotspot. So please please guys, give me a fully tested crash proof way to do rooting. I don't want to brick my device ( No one wants but in this case if it happens I can't find some way on the internet to reverse it). And you can also suggest any before hand precautions like full Backup of current system image etc etc. that will help if something goes wrong.
3] I already read a few threads on XDA about this issue but I cannot understand properly, so please don't provide links to these threads.
4] Also please provide a list of official and unofficial ROMs for A5
Thanks in advance
I have to read some pages to find a good tutorial but I'll find one. I root Samsung phones all the time. Its not going to brick your device. Asking here was smart, don't trust any website you find off google without fully understanding. Also, you can not install stock ROMs from custom recovery, only from a computer. That process is easy. Download the firmware and flash it. The other choice is custom ROM and recovery. Let me know what option you want to go with and I'll explain more. There are good custom ROMs, ressurection remix. Lineage os. Ice, tipsy is a good one. I use RR on my S5 and s7

Thanks for reply. I really appreciate it.
I read your reply but can't understand it fully. The reason is simple- I currently don't know what is Custom recovery and Flashing. Please explain these terms first and then I will tell what way I want.
Thanks.
A custom recovery allows you to flash zip files and operating systems from your phone directly, but only custom operating systems, not the official Samsung firmware. It is safe to use. Flashing stock firmware is the operating system as Samsung released it with nothing changed. You can gain root access to your device on stock or custom. Usually custom removes the carrier and Samsung stuff that takes up phone memory. It depends on what you want to use your phone for.
OK I go for samsung stock (official) ROM
Flashing is installing the contents of the package to your phone with a special tool like Odin or a custom recovery. And recovery is the menu on your phone from which you can restore backups or flash files.

Create an account on this site, it is free. Locate firmware 5.1.1 for your device, and make sure it is the same as your cellular service provider. So if you are on AT&T download a5 5.1.1 AT&T firmware file. It will be a large file. Once you have the file you will need a computer application named Odin. I will post a link for it shortly.
Hey wait a second. there's 6.0.1 or 5.0.2 files present. no 5.1.1.
Sorry, I replied too late. Actually caught in busy work.
Ok, I googled to know more about rooting etc. etc.
And I got a few uderstanding.
Then I re-read your replies and fully understood them.
Then something came to my mind:-
I am currently on 6.0.1 and Want to re-install it. So I currently downloaded 6.0.1 firmware from sammobile.
So, I don't know Odin can reinstall firmwares or not.
Just for your knowledge. See If we are going right or not.
Thanks
Hey, Anyone out there, please help me.
Might You Mygalaxya
