When you root, you're rooting the ROM. When you install a new ROM, the old rooted ROM is gone. Try the newest iRoot

Make sure you enable USB debugging .

If that doesn't work, look in the tutorial section for the ultimate root tutorial by @sniper47 .

For your IMEI, you can try to write them through engineering mode.

If that doesn't work, then you'll need to root and restore NVRAM from someone who has the same phone as you.
