Hello
I would like to backup the current firmware my 1020 is using (Lumia Black), to be able to flash this very same version back, in case I have problems or don't like Cyan or Denim.
How do I do that? I read on http://ift.tt/1snGTlY that :"don't flash a dumped ffu (from ffureader mode of a working device), as even though it might work, DPP will conflict and phone OVK will be invalidated, requiring you to obtain and enter a PVK to add MSA/access store/etc"
Is there a right way to do that with thor2? Can I get more information about backing up the DPP, OVK and PVK? Anything else I should be aware of?
If there is no way, how can I download an old version (lumia black or another WP8.0) for a Telus RM877, product code 059T790?
The only link I see on http://ift.tt/1U8lCmM is 3051.50009.1424.0000 which is cyan, while I think I need 3051.40000.1347.1001
I'm thinking of cooking a custom rom following http://ift.tt/1NoX3OT but that would be quite complicated to just backup an old version :(
Thanks!
