That won't make any difference with bootloop - bootloop is bootloop; recovery is not available.
OP - Your only option is to get a stock from from Samfirmware, boot into download mode & flash it with Odin (How ? Stickied thread titled 'Flash stock firmware' near top of Q&A has instructions.
If this is successful, this won't wipe your stuff. However...
Sometimes this isn't enough on its own & you still end up with bootloop after flashing stock & still need to do a factory reset.
So, try it & see.
P.S - We presume you've already tried booting into recovery; if you haven't you deserve slapping for making a thread first. You're expected to try the obvious before you post.
If it's important enough to cause you grief if it's lost, back it up. No excuses

If you don't know how to recover if things go wrong, what are you doing flashing custom roms ?
