Unhappy My father is going to kill me [URGENT]

hi guys i hope you are doing fine ..

my father's HTC one is screwed up

simply I opened the boot loader and flashed CWM recovery

the problem is the root didn't install perfectly and I had to wipe the whole phone witch affected the stock rom :/

I had to flash a custom ROM without doing any s-off/on

The new ROM is installed perfectly but root is not working at all!!!

I now can't go back to stock OR get the phone rooted :/

What do I do, it's not my phone
Device: Samsung Galaxy SII (I9100)
ROM: JεℓℓySℵα℘ v7.0
Kernel: Apolo v4.13 Regular
