Hello folks.
Well, I don't know if it is a problem with their servers, a problem with our computers or with anything else, but today I could install the software and recover my lumia 640 XL.
I'll try to descript what I did and then we may get into a conclusion
Well, at first, I downloaded the windows phone recovery tool installer.
No deal.
After that, I downloaded the standalone drivers and rebooted the computer in advanced recovery just to disable the digital signature verification for drivers.
No deal.
Next, I downloaded the nokia phone recovery tool, which this time installed Microsoft Visual C++ 2010 and some other things and, guess what? Error.
I don't know what took me to go there and try clicking to run the windows phone tool recovery again and, guess what, IT DID WORK.
Guys, I don't know what happened here, if it is a miracle or not, but my phone is safe and sound now.
I think that nokia software installed something that allowed me to do it, don't know, maybe Microsoft did it.
I hope it can help someone.
