Reboot into CWM and do a Data Wipe / Factory Reset, Clear Cache, Dalvik Cache, Then go to "Install .Zip From SD Card" Install your stock firmware or a custom ROM!....I think their are a few apps out their that can do this, Or has that feature built in! :good:

I think you should flash stock firmware downloaded from www.samfirmware.com for your device via pc odin or mobile odin

I think installing clockworkmod for wiping isn't an option. The op flashed stock Rom probably because he wants his warranty back
Installing clockworkmod again would void it again. If the stock Rom you downloaded is the one you had before rooting, then try flashing it again. If it's not, then download your originally out of box stock Rom and flash it with Odin.
Like...the same baseband version as the one you had before any modification of your system

You need to wipe it otherwise it won't boot up and if you had cm10.1 you must wipe your internal sd card to
if you install cyanogenmod and you odin back to stock rom the stock rom will simply not boot if no wipe was done!!!

That's a question too... How to do wipe, if all I have is official bootloader, with debugging OFF, and loop / stuck on SUMSUNG logo?

There are no my contry ROM. I stucked with bootloops and debug options OFF. What to do???! It's driving me crazy...
After almost two weeks of seeking for solutions all over internet, the problem was solved. First of all there are no way to root without debuging off via odin o any other tool. All what you have, is just to look for your original firmware of the phone, and it supposed to be four file package.
Looks like:
FULL_CSC_I9105PXXAMC2_I9105POXAAMC1_I9105PXXAMC1_DBT.tar.md5
FULL_MODEM_I9105PXXAMC2_I9105POXAAMC1_I9105PXXAMC1_DBT.tar.md5
FULL_PDA_I9105PXXAMC2_I9105POXAAMC1_I9105PXXAMC1_DBT.tar.md5
s2ve.pit
In this case it was german phone so files end with DBT.
CSC - as CSC
MODEM - as CP or PHONE
PDA - as AP or PDA
and pit file for re-partition.
The name of whole package is GT-I9105P-DBT-I9105PXXAMC2_Service-Firmware.zip
For those asking for delete dalvik/cache/factory reset, the solution is - RE-PARTITION!
I used also option Nand Erase All, just to be sure I delete everything.
All other operations goes as usual in Odin.
I can't post links here, bat me mercy on those looking for solution for days and weeks long.
So here is link that I found on some forum that leading to (thanx Goshhhh!!!) to Google docs, so download was just 5 min. long.
Here is German (DBT) package, and some other usefull links. Use G. translator to understand.

Have patience,wait for 10-15 minutes.
First of all, you shouldn't have used Rom manager. It bricks our device
Read the guide in the top of general section and install a proper recovery from odin.
Maybe the zip you have downloaded is corrupted. So download it again and try.
Make sure you are on official gingerbread(2.3.x) and not froyo(2.2)
If none of this works,there is something seriously wrong with your device.
But don't worry,you can flash stock via odin and revert back to factory state.

Which customize ROM?
For customize ROM you need with ODIN instal Clockwork Mod Recovery (CWM).
http://forum.xda-developers.com/showthread.php?t=1339640
Now you can install custom ROM. Go in CWM and go on wipe data reset, wipe cashe partition in Advanced wipe dalvik cashe. Install ROM and again go on wipe data reset, wipe cashe partition and in Advanced, go on wipe dalvik cashe. Reboot phone. It need wait about 5 minutes for system up.

Do this straight away:-
1. Flash Froyo 2.2.1(4 package) of ur country.
2. Then flash Gingerbread 2.3.6(one package) of ur country.
3. Then flash cwm via Odin.
4. Flash the custom rom thereafter.
Since it seems a bit complex issue, u need to try this to ensure zero errors.:sly: Btw u can try above steps in ur spare time.
As for me, I always try all methods that I know b4 concluding anything.

Thanks for the answer but u didn't read what I wrote. I've downloaded one from sammobile but it contains only PDA file and after installation it gets stuck in SAMSUNG logo and doesn't turn on.

You need to perform a full wipe (system, data, cache, dalvik cache) in order to go down, which will wipe everything except your internal storage. You can use Titanium Backup to make a backup of your apps and then restore them after you've flashed the cm-12.0-YNG1TAS2I3 zip. Titanium requires root, so if you don't have root you'll need to flash SuperSU in order to use it.
Why do you wanna downgrade good sir? is there some problems?
