Getting back from RedStone to 8.1

[DzieX]

Hi Guys,

I've forced upgrade my Lumia 830 to Redsone by using this method from nokiapoweruser.
Everyting worked fine but I decide to get back to 8.1 to test new .122 build. Unfortunatelly when I try to do it by WDRT after tool trys to switch my phone into flash mode error appears. I can see flash icon for a few second and after that windows starts to load. I've tried to use different PC, different usb cables and different usb ports with no result. I've also tried to use Nokia Care Suite (newest version) but it claims that this model is not supported (RM-984).
Does anyone has idea what to do?

Best Regards.

you have crapped your registry. the changes you made to your registr in order to install redstone you got to fix them or your phone is dead. lol

My phone isn't dead. It works on build 10.0.14267.1004. Does Hard Reset restore registry as it was or should I do it manually?

Select the cannot detect device option in WDRT and flash. I've reverted my 640 using that method though it never gave me an error to begin with.

Yes and hard reset does reset the registry.

 

[DzieX]

Already tried with same result.

 

[pankaj981]

Tried the method after the hard reset?

 

[DzieX]

Yup.

 

[pankaj981]

I guess your only last try would be to perform a dead flash using Nokia Product Support Tool. Try an old version and select the product from the drop down. You'll have to first download the appropriate firmware from some place else or use the firmware downloaded using WDRT.

You mean Nokia Care Suite? I have version 5.6.134.1513 and it seems it does not support this device. Which version do you suggest? I tried to find older, but found nothing.

 

[DzieX]

Ok, so for anyone with this problem in future - use nokia care suite 5.3.112. You can get your software from lumiafirmware.com

 

[pankaj981]

So were you able to revert back to the old firmware?

 

[DzieX]

Yup, but only by using Nokia Care as I mentioned above.

 

[pankaj981]

Yeah that's what I mentioned above...Nokia Product Support Tool. Glad that it worked.

How do you load the firmware into NCS? Can you please do a step by step. I have installed the version you mentioned.
I have downloaded all the files from lumiafirmware.com.
Lumia 1020 stuck on red Nokia recovery screen (flash, maybe)

Can you do a step by step on how to load the firmware into NCS?
