wont boot up , cant enter download, recovery mode - Samsung Galaxy S7 Questions and Answers

hi , so i had super man rom 1.4 installed , then thought its time to upgrade to 1.9 . I got the rom file into my phone, i updated the modem and bootloader through download mode and now i cannot boot into recovery or download mode , its stuck on bootloop . what can i do to fix my s7? adb cant seem to find my device now, i think because i didn't turn on usb debuging before doing theese things.

Try flashing Stock JB ROM by Paplu using SPFlashTools.
http://forum.xda-developers.com/showthread.php?t=2167244
I never flashed LeWa OS but don't Update Over the Air (OTA) as it might be downloading the update for that device (as it a ported ROM (I think)) the ROM was actually made for.
And don't worry. All of us had bricked devices at some point of time.
I prefer you use SPFlashTools on a Win 7 PC as drivers are a bit complicated to install on Win 8 as they are not signed. After that, download CWM img and flash it using SPFlashTools (tutorial to flash just recovery is also given or you ask if you are not able to do it) as recovery flashed through Mobile Uncle Tools also doesn't boot after factory resets and a couple of more situations.
