[Q] How to check root status and warranty reclaim

[badboys3]

I recently bought used (few weeks old) Samsung Galaxy S2 and i want to check is it rooted.
1. How can i do that?
I read that there are few ways, but how can i be sure that the phone is rooted?
-On the welcome screen there is exclamation mart in yellow triangle.
-I have the icon Superuser, but when I open it says "No apps in list". Under "log" there are few "Titanium Backup Allowed", one "Titanium Backup Denied" (somewhere in the middle), and one "Root Check Basic Allowed".
-I installed "Root Check Basic" from market and it says "This device has root acces!"
-When i start Titanium Backup I get picture similar to this http://galaxys2root.com/wp-content/uploads/2011/10/att-galaxys2-root-maclinux-7-690x416.jpg

But...
-I copied 01_Sherbet.ogg (sms sound) which is located in /system/media/audio/notifications to my computer, then i amplified the volume on this audio with SoundForge. This new audio with amplified volume (with the same name) i copied to my phone over bluetooth (in default location for bluetooth transfer files). Then i tried to copy/paste that file (in Astro) and overwrite over the old 01_Sherbet.ogg file. But i get this message:
Copy error
java.io.FileNotFoundException: /system/media/audio/notifications/01_Sherbet.ogg (Read-only file system)
If my phone is rooted, how can remove this "read only" setting for this file and overwrite it?

-Since i dont have wifi router (yet), i made ad-hoc network (for internet), but my S2 doesnt see it?! My Kaiser (wm6.5) and my laptop (windows 7) see it and can connect to internet just fine.

2. With rooting i lose warranty. But how can i gain warranty again (if one day i need it)? Is there any way to undo rooting, or should i flash it with stock rom, or...?

1). Your phone is rooted, you'll need to remount /system as R/W in whatever root file manager you're using.
2). Boot into download mode (vol down+home+power) and check counter. If it's >=1, your only option is a USB jig, and if that doesn't reset the counter (but does get you into download mode), you'll need to flash an older bootloader.

What exactly do you mean by "remount". I am using Astro, but i didnt find any option for that. If it is easier to do this in some other file manager tell me which, and i'll use it instead.

2). Boot into download mode (vol down+home+power) and check counter. If it's >=1, your only option is a USB jig, and if that doesn't reset the counter (but does get you into download mode), you'll need to flash an older bootloader.

When im booting in download mode it askes me to press Volume Up if i want to install new firmware, or press Volume Down if i want to cancel. If i go to cancel, it just boots normaly. How can i exit the download mode safely without installing new firmware? And where can i see that check counter?

Flash stock rom reset custom rom counter with usb recovery jig .

When im booting in download mode it askes me to press Volume Up if i want to install new firmware, or press Volume Down if i want to cancel. If i go to cancel, it just boots normaly.

How can i exit the download mode safely without installing new firmware?
As above vol down or remove battery .

And where can i see that check counter?

As above continue to download mode vol up see counter remove battery .

1. I manage to remount RW some folders in Root Explorer (unlike Astro, this one has that option, and it is located in upper right corner of the screen). But it wont remount RW anything in /system (which is exactly what i need). Is there any other way to remount RW /system?

2. I check the counter and it says 1.
What does that mean?
And what should i do when/if i want to reclaim my warranty?

3. One more thing... In some aplications (like Astro) i have some commercials in lower part of the screen. Is this normal (for rooted phone), and how can this be removed?

1.

What does that mean?

One as single digit 1 means one invalid rom flashed .

And what should i do when/if i want to reclaim my warranty?
set it to zero with usb jig

Advert supported apps normally show adverts as part of the T&C you signed up to for that app .

ROOT has nothing to do with adverts .

AdFree from the market may remove some of the adverts .

Thank you JJEgan very much. I really approciate it.

When i want to regain warranty, i should set counter to 0 with usb jig.
-Is that all or should i flash some rom (stock)?
1. And if i should flash stock rom where can i find it?
2. Are those stock rom's country/region/network/etc specific or is it the same for all SGS2's?
