    flash Lumia 920 firmware on Lumia 820!!
    Sorry, I should make myself more clear, I was talking about the 820 firmware not lumia 820.
    I flashed the Rogers 820 pre-portico rom on my phone and trying to update via phone now, then I will try flashing the EU ROM GDR2....

    Selected care suite external
    Selected "work offline"
    File>Open
    Selected rm-821
    Programming>recovery

    Start
    Verifying package...waits a few seconds
    Recovery Failed: Unable to get error message

    Edit: It's says I'm currently rm-820, but I'm assuming this isn't important and I can flash rm-821? It's still a lumia 920

    Try disconnecting the phone from the computer, start, then when it asks you to soft reset, connect it again, do the soft reset, then click retry.

    Doesn't even seem like it's getting to that point.

    Can you post a screenshot please?

    Some progress. It gets further before failing with this:

    It seems a lot of people who have the "RM-820" model are having this problem.

    After all, they are different variant codes.

    Try replace the "821" with "820" in all of the 11 files, see if that works

    ADDED: Also, is your phone turned on?

    Phone is on. I'll try renaming.

    Rename just causes more errors. At this point, I'm assuming no one with an ATT version of this phone has gotten this to work?

    Just finish flashing the RM-821 EU GDR2 + Amber ROM on my AT&T Lumia 920! :D
    I had to first flash the Rogers pre-portico ROM and then did 2 OTA updates. (Others say only need to do one, but I wasn't sure if one was enough....)
    Then after that, I flashed the RM-821! GDR2+Amber ROM!

    and i'm a 'she' btw :P

    Renaming only the name of the file won't work. You need to edit the content of the file via notepad.

    You can't flash a 920 ROM to the Lumia 820.

    Unless you're referring to RM-820 in which case it will be fine.

    The ROM is unlocked

    What LTE band does your operator use and what variant of 920 do you have?

    The NA ATT builds of RM-820 will not flash directly to RM-821. You need to flash to the Pre-portico Rogers RM-820, do the OTA update then you will be able to flash any RM-821 build you want (including this amber build). For more details please review the linked post (#52). Worked for me. I no longer have an LTE icon but my speed tests are in the 5-7mb range so I'm happy.

    I'm stuck at step 10, it's giving the error of invalid signature.. I have already renamed the file from nokia/packages/rm-821, but I'm still getting the same error..

    edit: it's saying C:\ProgramData\Nokia\Packages\Products\RM-821\RM821_059S6R5_3047.0000.1326.2002_068.vpl has invalid signature.

    what shall I do?

    Also, any ATT users have issues using LTE after updating?
