Check the tailhead.bat - it can to show a file content from certain line to a another line by number.If you have the tailHead.bat you can:

@echo off
::==========================
:: 
set file=text.txt
set "line1=I need only the lines starting from here SOME IMP TEXT"
set "line2=I need it till I find this line SOME IMP TEXT"
::========================
for /f "tokens=1 delims=:" %%a in ('findstr /n /c:"%line1%" "%file%"') do set "l1=%%a"
for /f "tokens=1 delims=:" %%a in ('findstr /n /c:"%line2%" "%file%"') do set "l2=%%a"

::echo %l1%
::echo %l2%

tailhead.bat -file=text.txt -begin=%l1% -end=%l2%

this will include the lines. if you want to exclude them you can increase the begin line and decrease the end line with set /a
