Easily Flash any Lumia 920 with full Amber/GDR2 features!

[juan6996]

That's largely the same problem I'm having at the moment. I've flashed the Rogers ROM and am trying to go to ATT Dev Rom, but can't manage to get the phone into recovery mode now. If I hold the volume down button for a long time while starting up I get the exclamation mark, but every other time it boots up to the OS. Dang

Alternatively, you can just keep doing OTA updates until you're updated to Amber straight from the Rogers ROM.

I couldn't wait anymore and did this last night. Everything is working good so far, and while I don't need to tether its great that I have that option now. I am already paying for data, at&t should not have any right to charge in how it is used. Glad to have datasense, need to set that up and try it. Thanks!

Yeah, that's what I eventually ended up doing after trying "volume down + power button" a dozen times or so. I've been lurking on this thread for a few weeks now, my willpower lowering with every "Amber update arrives for (insert Lumia device here)" article that hit the site. I was just afraid of getting my $400 phone borked because I was too impatient to wait. Thank you so much for the guide and ongoing support, Juan!

Now just watch as AT&T releases the update tomorrow, lol.

thanks for the guide you done but ota updates come online for my phone but i left the country and now phone cant find updates says your phone is up to date but it runs 1308 instead of 1326

Yea, I cant get the Nokia Pro Cam app either, I even tried sideloading it using the developer tools. Also, my data speed has dropped tremendously after the update. I was at 20-30 Mbps before where now i'm doing good to hit 4Mbps and that's trying both LTE-1 and LTE-2 AP's. As nice as the update is I might go back to an att rom when they come out or even try another rom.

Hi guys, thanks OP for this awesome guide but I have a small question, it works with a retail version? I mean, the unlocked version that any retail sells, I'm from Argentina, I don't know if flashing with this ROM will affect anything like the 3G bands or something.

Thanks!

Mart?n.

For Nokia Pro Cam, I kept getting error.

To fix that, I did the fiddler trick described here ->
Windows Phone Tips and Tricks


Now I have pro cam.

yes, you must follow all the at&t steps. And your phone will remain sim-unlocked.

Does this mean flashing will lock a previously sim-unlocked phone?

If so, will the previously used unlock code work again?

Your phone will remain unlock. When you unlock a phone, it remains unlock for life, no matter what you do to it.

guys, please help. The product support tool cannot recognize my lumia 925.

by the way, My firmware is 10328.WP8_CXE_GDR2(wpbldlab).20130613-1716 and product code is 059S539



i think it is a developer phone or a test phone.

thanks for those who will help me.

Re: How to flash ATT Lumia 920 with amber

Everything was going fine, however, in the middle of flashing my phone, an error popped up on my computer screen and the flashing stopped. My phone turned off and it won't turn back on. Methinks this is not a good sign. Any ideas?

If I flash my phone, will I be able to download the future updates (GDR3/Win Phone 8.1) or will I have to flash it again?

Yes.

I flashed manually to gdr1/portico and I got gdr2/Amber OTA.

No need to flash again.

i have overcome this but now i have different problem now when i start i swith the phone to flash mode while plugged in it shows me '' ! '' symbol and restarts and launches the phone again always same help me please

Uncheck Automatic Product Detection, then select open product from File menu, select product, select Programming, Refurbish

Rogers GDR2 ROM is available via Product Support Tool so one can download directly and flash, no need for OTA updates.

My computer won't even recognize the phone because I can't even turn on my phone. I'm pretty sure the battery had plenty of charge when I started the flashing process, so I don't think that should be the problem.

Plug your phone into the charger, and hold down Power, Camera, and Vol down keys. It should turn on. It has to be connected to the charger.

Tried that just now; didn't get any results. I think the issue is that the flashing process was interrupted, thereby leaving me with a completely wiped phone with no OS on it.

I just successfully flashed my phone. Amber apps installed just fine. Can't comment on tethering as I don't use it. Thanks for the guide, Juan!
