SOLVED.After hours and hours searching the internet i finally found and downloaded original stock rom, in dedex format, and then extracted browser.apk from it. After that i put broswser.apk into sys folder of phone(via Root explorer) and set appropriate permissions , so that they look alike other's app's permissions (rw-r-r in this case), then i rebooted my phone and Voila
everything was fine, my old stock browser was back <3. I just needed to dload and install ChromeBookmarksSyncAdapter_blackhand1001.apk from this thread
tnx to blackhand1001, so i could sync my boomarks from PC Chrome to stock browser on my phone.
