Have you used windows recovery tool..?

I have Nokia Lumia 620 and installed the windows insider and it wont download any updates via internet. So I thought roll back to windows 8.1
The problem is it needs to download 1.5 gb and I have 512 kbps internet.
So I used fiddler and downloaded the 1.5gb file using download manager.

Below is the location of my file as created by the Windows Device Recovery Tool.

"C:\ProgramData\Microsoft\Packages\Products\RM846\RM846_3058.50000.1425.0001_RETAIL_im_india_233_01_450672_prd_signed.ffu" I replace that one with downloaded one and flashed it.

After I upgraded again after some other builds. Its working fine now.
