Yes, if ur trying to root via ur stock recovery.

You need to read a lot more mate.
Here's a good place to start.
Read this too.
BTW, stock recovery is a special mode in ur phone, while Odin is a software that runs on Windows.

Will removing the ROM make my phone faster?

Hello,
I have Omega v19.1 ROM right now and it feels like my phone is slow and tired. Will removing the ROM or go back to normal like it was when I bought it make it faster/clean it?
If so, is there a guide here on how I can do that?
Thanks in advance!

What do u mean by 'removing the ROM' and 'going back to normal'?
Do you want to return to stock? Or to ur previous ROM? Or do u want to remove bloatware??

Its really easy.
Just search for 'Stock Firmwares' and u will find many threads on XDA. Or u can visit sammobile.com.and choose an appropriate firmware. Then download it.
Flashing is a bit more advanced. I suggest you read about Odin and flashing stock roms.

Going back to stock should make your phone a lot worse/slower.
Thats how you root and stick on a custom kernel at the very least.....to remove crap that you couldnt do normally.
Like theunderling said, stock firmwares do contain bloatwares. Since ur on Omega v19, why not update to Omega v21 (preferably after a full wipe)? Maybe that would speed up ur phone...

Search for 'Philz kernel'.

Save it to ur external SD card.
Flash that in stock recovery..

Ohh.. ok..
Flashing via Odin can fail due to a number of reasons, which is why I always suggest Mobile Odin for flashing and stock recovery for rooting.

Try using 'Root checker' app on Playstore to verify root access..

Try using another app, like a root Explorer.

Huh? Is ur previous issue solved?
Have u confirmed that you are rooted?
The root folder is not a special folder. It just means the lowest folder level.
For example:
You have a D: drive with a folder Backup, with another folder Messages inside it.
Like this - D:/Backup/Messages
The root folder here is D:/
get it?

S2 i9100g bootloader unlock

Can anyone help me how to unloack my galaxy s2 i9100g bootloader?
Running on 4.1.2 jelly bean.

Why not ask or search in this thread?

To unlock bootloader, simply use your phone. One of the few good things about Samsung is they don't lock stuff down, comes already unlocked.
Unless you were getting terminology mixed up and actually wanted something else?

Have you rooted your phone or have you only installed cwm recovery? You can open cwm recovery (=bootloader) by pressing "power+home+volume up" (I hope you knew this ).

The bootloader was unlocked all the time. Since you flashed cwm, the cwm bootloader is aviliable. What happens when you press "power+home-volume up"?
