WiFi and Bluetooth not working after firmware update?

Hello everybody.
I'm having a problem with my Samsung Galaxy Ace (GT-S5830L). A few weeks ago I updated the firmware from Android Gingerbread (2.3.4), to what was supposedly going to be 4.0 but ended up as just 2.3.6. Changes were at first unnoticeable.
Now, if I try to turn on WiFi, it only works like 1 out of 50 times. The other 49 times it throws an error.
If I try to turn on Bluetooth, my phone freezes and I have to take out the battery. Same thing happens with portable hotspots ("Mobile AP"). However, USB tethering works fine.
I hope someone can help me so I can fix this problem.
Thanks in advance.

Thank you, but...

That's just the user guide and the Samsung Kies download. Not what I wanted Confused

And I don't think my carrier issued the update because I had to make a Samsung account in order to install it.
Any ideas on how to switch back to the previous firmware? Or maybe I should boot into system recovery mode? I don't know what to do. No matter what, don't tell me that I should factory reset my phone unless it is completely necessary. BTW, I'm planning to get a new phone in a few months, but living with this kind of WiFi problem... sucks.

Thank you anyway.

So far when we need to go back.

It's done at the carrier's counter with their "flash" tools.

But your comment about no reset worries me. Your first priority is backup if you haven't.

I don't know what happened. I think my phone is trolling me. WiFi works fine now. However I'm sure it will stop working by the time anybody reads this.
