    Rogers is rm-820 and so is ATT Dev. I think Juan knows whether this is possible for sure. I think he wrote somewhere that he went from French (rm-821) to ATT Dev (rm-820). I let him confirm this though.
    Yup. Originally I flashed the Rogers pre-portico, then French ROM. Then I flashed the ATT Dev ROM to try to get tethering working, and I don't remember having to do anything special; it just let me flash it. But I suppose YMMV.

    Did you switch the "Access Point" settings at all? That will kill your tethering capabilities (as I discovered).
    No, tethering got killed all by itself...

    does it look exactly like this? If yes, possibly the file is corrupted. re-download it or use a different source.

    Here is the .vpl file for you to compare. See what happens if you use this intead.

    Nope, it doesn't seem to work, I'm having the same problem. I'm downloading the version that appears right below the first one on the page you posted. The one that says

    I really don't know why you didn't download the first one?

    which version of NCS are you using?
    the posted here should work fine. I've used it myself to go from Rogers Amber/GDR2 to ATT Dev

    I was using a 2013 version. Too recent version. I hope this version does the trick.

    that should work too, although I have not tried the ATT Dev with the latest 2013 version. Hope it helps
    don't forget to click the thanks button

    edit: I just tried NCS v 5.0.0 2013.38.3 and the files passed.

    just to cover the basics:
    once you open Product Support Tool (offline)
    go to File, Open Product
    type RM-820
    then Programming/Recovery
    Update List, check off update automatically (just in case, don't think it matters)

    still not working? Then I hope somebody else has an idea. Cause I don't

    Edit: Did you remove the CRC check numbers in front of the filenames? Take a close look at the image I posted. When you downloaded the files from the link I posted it contains the CRC numbers. The files have to exactly look like the ones in my posted image above and you need to remove these numbers. I think that is your problem

    check here (I just googled "vpl has invalid signature" :) )

    Ok, I already flashed it. The problema was as I was focusin only on the VPL file and I hadn't realize I had also to remove the hash from the other files. Lol, sorry guys it was all my fault. Thank you for your patience and help.

    for anyone interested, I found a solution to having a complete rom with working internet sharing after keyboard fix...I'm using the Euro Australian/new Zealand 3049 rom as an alternative to the French and Rogers 3047 roms and it is great! here is a review I posted on xda Dev, a part of the member "Snickler" thread: xda-developers - View Single Post - Lumia 920 Amber Update via Rogers Dev ROM I have reason to believe that internet sharing is permanently fixed because I started the access point app by accident after using internet sharing all day and it didn't break the feature on this rom, not sure what would happen if I updated access point app, but will test this later.

    could you comment whether this would allow tethering on any plan, like the French rom, which lets you use tethering free even on a plan that you would have to pay for otherwise?
