      sorry for my lack of experience on this but can you tell me is it good or bad?

      Rooting is not recommended if you are not a developer.I myself not rooted my phone because rooting makes your android more vulnerable to threats and bugs.

      I ment it for TRIPPING FLASH COUNTER. Is it bad or good if it trips flash counter?

      Samsung Mobile uses a custom binary counter to keep track of any Modding of firmwares and kernels done by users of their phones. Any flashing of roms/kernels not signed by Samsung will trigger an increase in this counter which can be viewed by putting your phone into download mode.

      Why is this important to you? This officially voids your warranty and tells warranty centers that you have broken your warranty which can give them rights to refuse or charge you for servicing your phone. Flashing a stock Samsung Note firmware signed by Samsung may also trigger the counter.

      You can use triangle away to reset the flash counter.

      Ask your problem at the xda thread.The casual tool is yet to go under improvements so you should ask the developer directly at.
