[Q] STOCK ROM and all went wrong

Dear Friends,

I was trying to root my phone. I downloaded a STOCK ROM using Desktop ODIN and after the ROM was downloaded, the phone started and I keep getting errors like these

Unfortunately maps has stopped
Unfortunately the process android.process.acrore has stopped
Unfortunately Google Play Store has stopped
.
.
And so on

I have tried with N7000XXLRK_N7000DBTLRK_N7000XXLRK_HOME.tar.md5 and N7000DDLR6_N7000ODDLR2_N7000DDLR1_HOME.tar.md5 so far and I have also tried the Pre-Rooted ROM SGN_XX_OXA_KJ1_FACTORYFS.tar

My phone is un-usable as of now. I cannot even enter the menu. All i have to keep doing is pressing ok on these error messages.

Please help. How can i restore the phone back to normal?
