I'm left to guess your carrier issued this update and it has failed. It's back to your carrier's service counter to sort it out.
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.
That's just the user guide and the Samsung Kies download. Not what I wanted
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.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
