Issues with the Downgrade to 8.0 from 8.1U1 DP

[unknow91]

Hi! Apparently the Cyan firmware is out for my 1520 (HK CV) so I decided to downgrade in order to install the firmware! But every time I connect the phone to the NSU it says that it can't read my phone's data! Yes, I can transfer data from/to my PC! I don't know what to do! Should I wait?

P.D: And I tried the XDA's flash tutorial almost the same problem (the program can't connect to the phone)
P.D2: Last week I flashed my phone and it worked! So I guess the problem is Update 1.

Try a different USB port that you haven't connect your phone yet

I know my solution looks strange but it worked for me: Reinstall Nokia recovery tool (download from Nokia website) it will install the drivers again. Btw I'm on windows 8.1 x64 and a L1520

I tried with 4 USB ports and I even uninstalled the phone using the Device Manager and nothing happened!

That's what the NSU says! I tried that and nothing happened! And I'm using Win8.1 w/U1

It is Nokia Recovery Tool you need NOT Nokia Software Updater. They are two different programs....

Same issue, the solution is restart the phone and Working Fine!

I had no issues downgrading from 8.1u1 to 8.0.
I used NSRT.

Thanks everybody! After a lot of wiping (my phone and my PC), uninstalling and reinstalling the NSRT (an the NSU) it finally worked! Thanks everybody!
