    I got my 920 today and was able to flash it from ATT to Rogers without issue. I'm installing updates now but I can seem to download other ROM's off of Nokia servers using navifirm. Anyone else having access issues?

    Hi Games,

    Im not sure if the same has been answered by you earlier, but if so please just share the link instead of repeating yourself.

    i flashed from at&t to india some months back and have all the latest updates. but as it was mentioned it doesnt support 4g as of now.

    I am from karnataka and here vodafone will be most probably going directly from 2g to 4g as that is the bandwith they have bought. i wanted to know is there any way to enable 4g? or will some automatic update or changes take place once vodafone launches and i use a 4g sim once its launched? or flashing it all over again to Rodgers ROM is the only option?

    please advice. thanks again!

    First, your 920 must be SIM unlocked to use in Bangladesh. If it is unlocked, you can use it in Bangladesh with the stock AT&T rom itself. If you fancy flashing a country variant ROM, you would get the benefits I have mentioned at the start of the guide.

    i flashed from at&t to india some months back and have all the latest updates. but as it was mentioned it doesnt support 4g as of now.
    Sorry to be the bearer of bad news, but the 920 will not support 4G/LTE in India, even if it is running on a ROM which has 4G option. This is because India has TDD-LTE on 2300mHz band - the 920 does not support this band (refer gsmarena) - if you want to have a 4G ROM, you could try flashing it to a country variant rom which has 4G. I'm not sure if it's possible to flash back the rm-820 rogers rom; you could try flashing a country variant rm-821 rom which has LTE support (UK country variant perhaps?)

    Thanks Games.

    So i guess the only way i can use anything faster than a 2g in Bangalore will be to shift to Airtel as Vodafone doesnt have 3g in bangalore.. Painful decision.
    Thanks anyways!

    Hi, I would like to turn my phone to international variant because en-us lang is blocked and I can't get cortana on wp8.1
    It seems Nokia blocked the capability of the phone to apply en-us (i can get en-uk or Canada but no US).
    The thing is I am already on wp8.1, am I still able to install a RM821 rom and then get wp8.1
    I mean, even if I am able to install a wp8 versión since I'm on wp8.1
    will I be able to install wp8.1 again? because they stoped the dev preview, but maybe since I installed it before I'll be able to do it again, idk.
    Going from WP8.1 to WP8 is possible ? can it brick my device ?

    You could buy a portable 4G router which support the TDD-LTE 2300mHz band and then put voodafone sim in it and use.

    If you are on an rm-821 rom, you can flash another 821 rom straight away - already having 8.1 should not be a problem. I didn't know that they stopped dev preview - if this is the case, then you might not be able to install dev preview once you go back to windows phone 8

    can i flashed my phone directly from at&t custom rom RM 820 to BD RM821.
    as far as I know, you will have to flash the rm-820 rogers rom first (as per the guide)

    The instructions say: "(in top right of product support tool for store, the drop down list should show “USB - RM-820” or something similar)"

    When I plug the phone into my computer, it shows up as a Windows Phone in the File Explorer. However, I do not see the "USB- RM-820" showing anywhere. Are you sure you mean top right?

    What have I done wrong?

    If your phone shows up in File explorer, nothing to worry about, you are doing it right and can continue following the guide

    Ok, I got it work. It's a timing thing, it's kinda like doing the plug/unplug trick with WP7 and Zune to force the update.

    I think the guide should read top LEFT though, as you mean it will show up in the field that usually says "no connection", Correct?

    Hi Games,

    I am in India and 'am using an UNLOCKED AT&T Lumia 920 with Black update. I wish to flash to RM-821 for India. Two questions:
    1. Can I still use your guide as it is to flash Indian RM-821 (the guide says AT&T pre GDR3 update Lumia 920)?
    2. Will flashing Indian RM-821 still enable me to automatically receive the Windows 8.1 update as and when it's rolled out in India?

    I have a more basic question. Since my Lumia 920 is already unlocked, data tethering etc. is already working, however, data sense is not there. Since mine is unlocked AT&T Lumia 920 on which I can install and run India specific apps as well, should I still update the RM-821 or wait for AT&T to roll out Windows 8.1 update? I am confused, your direction will be of real help.

    Thanks a ton in advance.

    Even though I have not tried it - yes, this guide should work for you even if you are on Lumia Black - follow the guide step by step

    2. Will flashing Indian RM-821 still enable me to automatically receive the Windows 8.1 update as and when it's rolled out in India?
    Yes, once you flash an Indian rm-821 rom, you will receive the 8.1 update when it is released in India (just like an Indian 920 would)

    should I still update the RM-821 or wait for AT&T to roll out Windows 8.1 update? I am confused, your direction will be of real help.
    I recommend you go ahead and flash the Indian RM-821 ROM, mainly because country variant lumias (like Indian 920s) are usually among the first to receive updates - plus you will have all the features like data sense etc and no fear of AT&T removing features in future updates.

    hi games
    first I have to thanks for your tutorial.
    in the next, I have to say my device is lumia 820 for at&t and RM-824, and the way you mentioned above is not available for me.
    but I have found this link that show all ROM for my device.
    my current product number is : 059M0F3
    and I've tried to flash to product code No : 059S0N1 VAR MX CV which is country variant and it's for Mexic.
    but the flash procedure goes wrong by the following error :
    "0xFA001304: Platform ID check fails. Reason(s): The FFU file is not meant for this product. The platform ID of image does not match with platform ID of the device."
    Already my device is unlocked and I'm using it on non-at&t operator service.
    can you advice me a way to find a country variant ROM for flash this device?
    I have to add this problems to what you've mention in first post :
    1- there is no option for message delivery in message setting
    2- there is no option for changing map save location to SD card
    with regards

    Hi, the method outlined in this guide applies to lumia 920s only. Flashing the rogers pre-portico rom to enable flashing other firmware is kind of an exploit found for the 920. I do not know if firmware with a different product code can be flashed onto the lumia 820 - you would do well to ask in the Lumia 820 forums here on WPcentral - link

    I have to add this problems to what you've mention in first post :
    1- there is no option for message delivery in message setting
    I'm sorry, but I do not understand what you meant. Is it setting for SMS delivery confirmation?

    2- there is no option for changing map save location to SD card
    with regards
    There is a solution for this. Go to the windows store and install SysApppusher- then open SysApppusher, under 'beta' section you will find an app named "Lumia storage check beta" - install that. After installing it, open it (it will be in your app list). After opening it, swipe to the right, under 'details' you will see maps - tap on change button under maps and below you can see a drop down menu for changing maps storage location - select SD card and you are done. But whatever maps you have already downloaded onto your phone cannot be moved across to the sd card; you will have to delete them from the phone first and then re-download them to the sd card.

    Try downloading the firmware from MrCrab's site - link - enter the product code you want to download the firmware for into the text box and it should display a list of files you need to download.

    Hello,
    Has anybody tried this in a Lumia 820?
    I have an AT&T Lumia, and I want to flash an international ROM to it. Actually, there is not a custom ROM for my country (Albania) for 820, so I am thinking of flashing an international. What do you suggest?
    Also, can I flash the custom ROM directly to it, without having to flash the ROGER's one previously?
    Thanks
