As the title says, I am asking whether i can use cyanogenmod installer via play store to unlock bootloader. I have stock rom and I want to install 4.4 roms and i got sick of waiting for samsung to release an update. So i am asking if I used cyanogenmod installer to unlock the device and then unroot by myself. After then can i install other custom roms just by flashing them? Is this a safe course to follow or do you suggest it would be better to follow one of the guides that shows how to install custom roms on S3 from start(stock rom)?

GT-S5830
S5830XWKTE
2.3.6
2012 March
S5830EPLKP3
(e-plus)
i tried to root it with cf-root. b3 b4, and the fix. no go.
and when i flash cwm5 it will only last for one boot cycle.?
WTF is goin on with this rom? just wont allow root access. i have tried a few version now of root and cwm. and having no luck.
i wanted to try this rom as it is lighter that latest russian version. and it locks on to wifi pretty instantly.
anyone tried and succeded?
P.s im not new to flashing ether, tried flashing cf-root with all version of cwm recovery, no go
Operator specific firmwares usually have locked bootloaders. I am not really sure but I think they have locked the bootloader.

you should know that samsung never ever ever ever lock bootloaders on devices.. its other OEMs SE,MOto,HTC who play dirty games. otherwise you would had a thread sticky here saying "unlock/relock bootloaders SGA"

One time I had the same problem and I just had to flash old stock recovery before flashing the root-zip.
To get the old recovery you just have to flash the file from here via clockworkmod.
After this rooting should work. I prefere rooting the phone by flashing the upd_1.zip from here.
Hi!
I want to root my active but I'm afraid that I can brick it or something.
I have it with the stock rom and the compilation number is 4.0.2.A.0.84.
Can I follow this tutorial? http://forum.xda-developers.com/showthread.php?t=2118343
Or there is one specific for the version I have?
Sorry if this has been asked before but it's not very clear for me what to do to root the phone.
Thanks!
I would advise you to read my rooting guide (in the stickies in general forum) and to follow the method for 4.0.2.A.0.62. It's really easy, but instead of updating to .62 you will update over the air to .84 (I hope that's working!)

Yes, that's right
You could use the tutorial for .62 or you simply try the program called "eroot"

Nothing to very about brother.:good:
First of all unlock your bootloader via sony`s official website. (i will give the link in .txt file)
Second flash any kernal via flashtool make sure you choose carefully between android versions i.e. use ICS kernal if you are on ICS,similarly GB kernal for GB and JB kernal for JB .
DONE..!!:highfive: I am not responsible for any harm to your device do it at your own risk

Unlocking bootloader and then rooting is the easiest way, unlocked bootloader will also provide manual settings of frequency which will indeed boost the phone. :good:
Root will avoid the warranty isn`t it . so whats the deal with unlocking the bootloader.

Unlocking is not the easiest way and it's not necessary. You are able too root without unlocking (check my guide, there are many methods) and you won't void your warranty, because after reflashing the stock rom, you can send it to the service center and Sony won't notice that it was rooted

Ya your guide is really helpfull and can root the phone without unlocking the phone. nice work sir...:good:
Well, first of all, many thanks for your contributions. Now I'm more confused. The main goal for me is to be able to free some internal space (remove stock applications?) Flashing custom ROM's is something I would like to but not necessary for now. So... for my first goal, I don't need bootloader unlock???

Its up to you whether you want a locked bootloader or unlocked bootloader. If you use a locked bootloader you will be able to flash custom Roms but you will not be able to flash custom kernals. custom kernal basically will increase your phones performance.
Its your phone your choice brother.. Both the method are Perfect. My personal opinion is that you should use the rooting method with locked bootloader hence, it will not avoid your warranty (if you flash the stock rom again after flashing a custom Rom).

Just try eroot first, it's the tool "for all firmware versions". It should work well! Download the tool and follow the instructions

If it's really not working, use the method for .587. There's a link to a tutorial by Abhinav2 and it should work then

Hello,
Some time ago I tried to root and install a custom rom for my lg l9 p760(v20i) but I failed; error was: "security error" at boot.
Now, bad ideas comes to my mind again and I want to repeat the process.
My question is pretty simple: in order to have a rooted phone with a custom CM rom, what steps should I follow, and most important in what order: root, busybox, unlock bootloader and then install cm recovery?
Thanks.

3 Root and then u can install busybox and cwm

Thank you for you answer.
So this is where i was wrong: last time I just rooted the phone,then using an app from Play Store I installed CWM then got that annoying "security error";
Thanks again and have a great day!
I'm gonna guess you used Rom Manager to install CWM.
From what I've read that's a big no-no on our phones.

Well no. All roms above ICS require a custom kernel for which an unlocked bootloader is required. You cannot run 4.4 sorry.

You can flash all stock based roms.
Any kind of cm etc roms that include a kernel to be flashed are a nogo.

Yes but you need to be more specific.. What phone (P what.., carrier etc), is your bootloader unlocked, all that good stuff.. short version is yes, but things are a little different on different phones.. It is a lot easier on everyone if you tell people these things.. not trying to sound like a jerk, but help them help you

As travioso said... We need more information on your device specifics.
Do you have a nandroid backup, pre CM or one of your stock ROM? If so, restoring a device backup would be the easiest method.

LG Optimus L9 P769, bootloader unlocked, but i have not done back up before installing CM.
He has cyanogenmod so of course his bootloader is unlocked.
You must flash stock kdz file to go back to stock rom. This General section has a sticky thread about it.
