Downgrading software

Nikki3 — Sun, 31 Jan 2016 18:22:30 GMT

So here it is, I went in to EE in October and showed them the issue with my wifi, they wanted to send my phone off for testing but as I hadn't backed anything up I said I would go back in, I had my baby a few days later so I didn't have the time. My toddler smashed my screen just before Xmas and now EE are saying they won't send it away now because I've had my screen fixed elsewhere even though they remember me going in before the screen was smashed. Does anyone have a link for Kitkat as EE plugged my phone into their machine and.are saying I need to downgrade the software to sort the wifi issue.

There is a huge thread here about downgrading:

Ooh, I used the ftf file from xda and my phone got stuck on the start up screen and kept turning itself on/off so I had to flash it back to lollipop. :s

Is your phone locked to a network? Have you ticked wipe data and cache?

I didn't tick them because it said in the guide it wasn't necessary. Should I try it again with those ticked? Was worried it was a corrupt file. A pop up always comes up with "script found, would you like to use it?" and I tick yes to that, is that right?

You should tick wipe data. Not sure about the script message, but make sure to exclude baseband.

@Nikki3 any news?

Nothing yet. Did tick wipe data and got 4.4 on OK but that did not solve the problem. I've spoken with people on other support forums and they have the same issue with no one offering a resolution. I went back into EE after downgrading, they ran a diagnostics and said the phone is fine. They can't figure out why it's not coming on.

@Nikki3 So if you flash KK the phone turns on correctly? And after you update to 5.1.1, problems show up?

The phone turns on correctly but the WiFi/Bluetooth problem is still there even with the Kk firmware. I saw on a different forum that the the same problem started happening to someone else after the 4.4 update, I was considering finding 4.3 firmware to see what happens.

Keep us updated. I don't know why those functions won't turn on.
