[Q] Bricked my phone... have Titanium Backup installed and TWRP... how to restore?

I have rooted the phone but have not upgraded the (Stock?) ROM for many months.

I was trying to get WiFi Tethering to work again and flashed a file that was supposed to fix it. It didn't.
(Edit: That file was "MD4HotspotMod-Odexed.zip"...)

Do I have to re-flash the last ROM I downloaded? I think it is still on either the internal storage or the external SD card.

"Power+Home+Volume UP" will flash a ROM, but I don't know where the ROM needs to be. I think I had to rename it "update.zip" and put it in the root of the internal memory last time...

"Power+Home+Volume DOWN" puts me into Team Win Recovery Project v2.5.0.0, but I don't know what to do in there.

(It is stuck at the glowing SAMSUNG logo when I attempt to boot normally...)

Thanks.

P.S. In TWRP, the last backup I did was apparently about a year ago... can I use that then once the phone works again, boot it up and restore via Titanium Backup?

The phone is working again, but now my WiFi won't work.

I think I'd like to just wipe the phone and start from scratch, but I've never done that before.

Should I start a new thread or could you or someone point me in the right direction?

Backup everything in internal to pc or external sd, also your apps, contacts, text, etc.

Click to expand...

Click to collapse

I backup everything by just copying and pasting to the external SD card using ES File Explorer.

1) What program do I use to backup my apps, contacts, text messages, etc.?
a) Apps: Titanium Backup
b) Text Messages: SMS Backup & Restore
c) Contacts: I have my Google account synced with my phone, so I think this is automatically backed up?

2) What program will make an exact image of my internal memory so it can be restored in completeness?

3) Is there an easy fix for my WiFi in the meantime?
