Problems/doubts related to rooting the phone - Galaxy S II Q&A, Help & Troubleshooting

I was going through threads on rooting, ROMs, kernels and bricking. Before reading threads about bricking I wanted to root my phone but after reading I got scared of bricking my phone which I think is difficult to debrick (unbrick).
Is it really the case that we cannot debrick the phone at home? Is it ok to root with such a consequence?

All I can say is if you're that worried about it, don't root your phone or flash anything. Leave it on stock & enjoy it.

Is it possible to change ROM without rooting the phone?
And what are the chances of bricking the phone while rooting? And if bricked what is procedure to make it as earlier

use this to root your S2...It is 100% risk free. However use only if u are on ICS

Also, read everything before u flash a rom/kernel..95% of them get bricked without reading or consulting properly

I read it, but I didn't not find anything written as it won't brick the phone. So just wanted to confirm even if I made any mistake, it won't brick my phone, right?

if you don't wanna brick your phone, then don't screw up in following the instructions

Look at method 1 in the link from my signature
It will not brick your phone as I now include cwm4

The thing is u are just installing CWM and busybox that gives you root by that method mentioned. Believe me i was also afraid and i rooted using that method..took hardly 30s lol
And it wont wipe anything..
Just go ahead..u aint flashing any inseure kernel or any rom..so there is no chance of bricking..Go ahead

i was trying to root my SGS2 using this method but i never found file CWM.zip file in the "apply updates from external storage" options. i tried to moving it to sdcard (main folder), creating a folder in sdcard and by moving it to folder android under sdcard (which is visible in those options) but couldn't find CWM.zip file. i use volume up + home key + power button to go to recovery mode.
plz help me regarding that why i couldn't find that file

Done with rooting.
Thanks all for the help

Superoneclick could be a good idea. Install it and just click on unroot. They say just don't mount the sd card and you'll be fine.

Pretty sure you already need root to use mobile odin.

Yep. Initial root requires a computer.
If you really need to root right now, download Odin and CF-Root on your phone and ask someone to borrow their computer or use a public computer. Move the files to the computer and root it in less than one minute and you're done!
i have a few questions maybe you guys can help... so here we go:
when you root with odin, it unlocks the phone giving you su right. does this also change your rom?
how is the launcher different than the rom? difference between flashing rom and kernal?
last one... when you install a custom rom, can you delete it if there are bugs to reinstall a different one or use the stock?

Ah that's why. Please read the rolled up sticky thread in this forum on how to safely root your phone. Then you can start loading custom ROM's on to it. DON'T rush take your time, read carefully and follow the instructions exactly. There are lots of benefits to being careful and patient and expensive mistakes if you rush into this. All the best and happy flashing.

Unroot S3 for Kies update

Hello guys,
I just started playing around with Android/ROMs/etc so forgive me in advance for what probably is a noobish question..
I rooted my i9300 using CF Root, and then tried a few ROMS.
Although, for the time being i decided to stick to the stock. Had it restored through CWM backup/restore function (Nan I believe).
But now, when I try to update it through Kies it says that the firmware version is not compatible.
I checked around and I've seen that I could flash the stock ROM and it would fix, although I would lose everything i have right now.
Wouldn't "unrooting" fix my problem? I mean, from what i can figure out, it's just copying cache.img and recovery.img to my 'boot'?
If so, wouldn't just putting back the stock files 'deceive' to update it?
Thanks a lot!!!

Use triangle away to reset counter, flash an unrooted stock Rom, do a factory reset, that should be or. You will be unroted and original status. Please correct me if I am wrong. There are also a lot of how guides here in the forum and on YouTube!

It was a great idea. Just did that, but apparently the firmware is still not compatible..
I also still see the CWM app in my app list..
Actually, rooting shouldn't interfere with updating via Kies, only OTA. That's what I read. Do you have the correct firmware region?
well its the one that came with the phone, so should be right.
would the cwm cause this? could i put back the original recover

Black screen after boot! HELP (URGENT

Hi, I'm new here so bare with me.
I just rooted my Samsung S3-I9300 hours ago. And I was pumped up, what I did later on is I installed bootanimation and I didn't quite understand how to use it and I still don't, but in the end I got it to work but the logo was too small but this isn't the problem. I entered recovery mode and I don't know what I extracted or installed and I rebooted my device and all I hear is the Samsung booting music and that's all. My screen is black.
Your help is appreciated.

Yes, it is booting. I can see the back button and the options button lit. It's just black.
BUMP.
I would probably wipe data in recovery mode, and last case scenario flash official firmware from sammobile.com.
This will make you lose all your saves and stuff though.
Wipe cache and/or full wipe. If still nothing, reflash ROM. It happened to me long time ago, nothing to worry about.

If you didnt make a backup, yes, use ODIN to flash a stock ROM.
You can find out which rom you currently have in settings/about phone.
Download the rom from sammobile.com and flash with ODIN.
