Have you try out CF-Root - SGS-XX-OXX-LPB-v5.2-CWM5 by Chainfire?

Rooting any phone can come with a risk, but it is a risk worth taking, also you could void your warranty when you root your phone. I used cf-root and for me it's the best root method.

It would not spoil you phone if you follow the instruction carefully.
Probably you will only get an annoying "Yellow Triangle" warning sign after rooting.

I seriously need help with this

Okay, so my Android 4.3 AT&T Galaxy S4 is rooted (through Kingo) and the only reason I did it in the first place was to flash CyanogenMod or some stock Android variant. Now I'm being told I can't install a custom recovery on my phone for two reasons. 1) AT&T locked the bootloader 2) I'm running Android 4.3.
Now, I'm considering unrooting my phone but even that's unclear and confusing, and it's hard to find people on these forums who are willing to help with these relatively simple (to the non-newbs, of course) things.
Can I flash a custom recovery? Can I run CyanogenMod or any good ROM? If no, will I be able to, ever? If no, how do I unroot? Would it be wise to just wait for the next update from Samsung or AT&T and install it so I automatically unroot?
Much appreciated.

im not confirm with it but i read theres a tool called "loki" with it you can unlock your bootloader and run custom firmware. but the rom must provisioned with loki.
search for it and read you in.
hope i could help you a little.

Can I CWM a non-development phone bought in the shop?

Do I need one of those "vanilla" developer phones if I'm to install a custom ROM on my Note 3? As far as I know, nope. You can root any Android phone.
I'm fairly sure that I can ClockWorkMod + install custom ROM on a phone I purchase in a shop. But I just want to make sure .
Thank you in advance .

You are joking, right ?
If not, yes.

Although my question seemed that of a noob, I can assure you I am not. My first rooted phone was HTC Tytn2 which I rooted using Duty's ROM's which I found here back in 2008. So no worries . Now I have a rooted SG2. I know all the procedures, safety steps and so on.
The reason I asked such a dumb question was that I had a 1% uncertainty regarding this, which I was unwilling to risk on.
As far as I know, the so-called dev-phones are simply loaded with a vanilla version of Android, no Samsung bloatware.
Anyway, thank you guys for calming my fears .

There´s only one Google Edition phone in Samsung, the S4. Still, you can get a "normal" S4 and still flash it like crazy.

rooting a device

I have a question which seem familiar over the internet but I am confused because of too man answers for :
I have a new brand (not famous brand ) phone , and I was thinking of rooting the device in order to have more ram but my only problem is that the warranty I know that it may be void after root but :
if i unroot the device will it still void or not ? and i hear that engineers in the companies they can know if the phone was rooted is it right ?
(Note : it is only unrooting without custom rom or flashing and my phone warranty is from the device comapany it self)

your warranty is void after rooting, but in my personal experience, no one even checks. it could just be customer support in my area, but when i try replacing a brick i dont tell them that i rooted, i just tell them my problem and they usually replace it.
p.s. i only did this once, my friends are the other experience!
p.p.s. and i dont think rooting can give you more ram, but i may be wrong.

You can set the CPU up higher and overclock it which will speed up the phone

if you are only seeking to get more ram i would advise not to root your phone because the only about of ram you are going to get is around 30mb's which pretty much means you can only run +1 more app which is not worth it. as for Warrenty voids. if you root your device and send it in for repairs, its voided, if you unroot it and send it in it should not be voided, some new phones have have a counter that can tell the OEM if the device is modified or not, this is only for most newer samsung phones. they can only tell if it was rooted that way if its an older device running Gingerbread and you unroot it ( delete your root apps) i dont think they can detect that it was rooted.

Your Warranty is voided as soon as you root your device (only if they find out in the Service repairs) pretty much if you break your phone and needs service repairs delete root apps and unroot.

@hopsin4444 please Read the OP before you post nonsense, Overclocking has nothing to do with what he wants and the only way for him to overclock is with a Custom kernel. :/

[Q] about flashing roms

I'm now using Samsung Galaxy S3 I9300 with android 4.1.2. Recnetly, I want to flash the S5 roms posted by other developers. However, those roms are in android 4.3 or 4.4.2. Can I directly flash it or do I need to upgrade my device to android 4.3 first?
thanks so much!

You can't flash a s5 ROM onto your s3, it will brick.

But the S5 rom is for S3. I found that in the S3 forum. Can you briefly explain why it will brick?Thank you

ok, i looked into the s3 forum and i see the s5 rom there.
this is either a rare instance where another phones rom is compatible or more likely what is known as a "port". it wasnt obvious right off what was the case.
either way, sorry for the confusion, it would be ok to flash that as long as its says its compatible with your phone.
generally speaking, you cant just grab a rom for any phone and flash it to another. that would result in a brick, and i jumped to conclusions and thought that was what you were trying to do.
as far as, if you need to upgrade first, im not sure about that.
some roms require you to be on a specific version first, otherwise it will bootloop after you flash the rom.
reason being, roms dont usually replace all parts of the software, but are built off or made to work with certain versions specifically because the use some of those non replaced parts to work correctly.
i would read through a few pages of the rom post. most likely someone has asked if it will work on whatever version or stated what version you need to be on for it to work.
if you cant find any answer, then i would ask the question there.
sorry i cant be of more help.
one bit of advice that i always follow myself, read into flashing back to stock and download all needed files and tools first. this way, if you have any issues, or just dont like the rom, you already have a backup plan in place to get your phone working again like you want it.
just my 2c hope that helps.
