Updating Nokia Lumia 710 RM-809 (T-Mobile/Rogers)

Hello all,
So after updating my Lumia 710 from Rogers, in the "About" screen of the Diagnostic Tool I see that I am on FW revision 1600.3007.7740.11465. This is a few versions behind what seems to be the latest version out there for unlocked variants of the phone...
So I found this page:
http://www.wpcentral.com/hack-t-mobile-lumia-710-flash-windows-phone-os-8107-new-firmware
Which claims that they have flashed the latest Indian firmware (8107.12070) for the RM-803 variant of the phone onto the T-Mobile (RM-809) version. However I am somewhat reluctant to try flashing an RM-803 image onto an RM-809, especially due to the fact that they support different 3G bands. What do you guys think?
Alternatively, I can see in Navifirm+ that the latest available image for the RM-809 is the Australian 8107.12050, so that might be a safer choice?
This will be the first time I try to manually update a Windows Phone... So what do you guys think? I really want to update it since there are some GMail syncing issues on the build that I'm running now.

I updated my lumia 710 from rogers (RM-809) with the RM-803 indian rom 12070 with no problems! Nothing is missing and it's now unbranded If you follow this guide it's really simple!

Thanks, Simon!
After reading your post, I gave it a shot and everything seems to be working fine I wonder if we should be seeing any battery life improvements like the Lumia 800 users?
Just something I should mention, though: I unlocked my phone so that I could use it on Wind Mobile, but after going through the flashing process, the phone became locked again so I had to re-enter my unlock code.
I didn't know that it was even possible for a phone to become locked again, after already having been unlocked...

I am thinking about getting a Lumia 710, and I am really surprised that you guys were able to flash a firmware from another RM-### without bricking the phone.
I currently own the X7 (RM659) from the Rogers and I was told not to flash the Belle firmware from the X& (RM707) since the phone will get bricked.
Nonetheless, thanks a lot for the info.
Which software do you use to flash? Phoenix or WP7 requires other tools? Never mind I found the post detailing how to debrand it.

The weird thing is... I tried to downgrade from the Indian (RM-803) 1070 build to the Australian (RM-809) 1050 build, and I wasn't able to...
It seems there is a small battery bug (Diagnostic tool doesn't display battery info) so that's why I tried to install the Australian one instead.
Whenever the next update comes along, I hope I'll be able to switch back to an RM-809 build... It seems like the safe way to go.

Normally you shouldn't... But the only reason I did it is because other people had successfully done it.
Also keep in mind that Symbian phones seem to be a little pickier - you can brick them just by trying to downgrade to the previous OS.
Edit: Well that's weird... My Battery Status randomly started working!
Edit #2: I just remembered I did a battery pull, so that may have had something to do with why it is fixed now...

I never knew it was possible to downgrade the OS for Nokia phones whether it is Symbian or WP.
Would an unlocked T-Mobile Lumia 710 work fine on the Rogers network? Do the GSM bands match?

It would indeed. The RM-809 model supports HSPA 850/1700/1900/2100. So it will work on any of the North American operators. (excluding the cdma operators like Verizon and Sprint, of course)
Actually, I bought my Lumia 710 from Rogers, unlocked it, and I am using it on Wind Mobile now (same hspa band as t-mobile).
Edit: I hope you're right about the downgrading thing, since that would mean that the reason I wasn't able to flash back to RM-809 was because of the fact that it's a downgrade, as opposed to something being messed up on the phone! I guess I'll find out when the next update comes along.

I am 100% sure you cannot downgrade Nokia firmwares without bricking the phone. I read about one method somewhere, but it was very complicated.
If I were you, I wouldn't be worried, now that you have the RM-803 firmware, next time there is an RM-803 update, you should be able to update via Zune/Nokia Suite without having to go through the method you used at the beginning of the post.
Now your phone is an RM-803 so Zune will recognize it as so and update it normally hence the beauty of debranding where you don't have to wait for operators.

Hello guys i'm new to the site.

I was wondering that too.
Also, there's two T_Mobile 8773 fw's listed for each color phone. One appears to have been released 06/04/12. The other 05/29 . What's the differences?

I think it has to be the same RM, download the Nokia Data Package Manager, and search for your RM-number you should be able to load any of the ROMs available there, go for the one with the highest firmware number

Hi John,
You won't be able to flash your AT&T phone with that firmware because your phone is RM-808 PC 059M7R4. Whereas the firmware you're looking at is meant for a RM-823 PC 059N4K5. So it won't work on your device. Not to mention that this firmware is a SWAP package which are only used by Nokia when changing motherboards in their phones before the original product code can be re-programmed (if they could be bothered).
You could ask at your nearest Nokia Care point if they can install any additional languages to your phone which I know they can do that for Symbian phones but not sure for Windows phones.

[Q] How to flash RM-823 on my RM-808

Hi all!
I have a question.
Is there any chance, or is there anybody who succesfully flash RM-823 rom on RM-808.
Do you have any ideas how to change these number? I don't care about LTE, because I don't have it in my country, so I would be really grateful if you help me.
Thanks
Vasek

You can't. The 7.8 update should be on Navifirm soon.

Well but I also need it due to language. So I hope there must be some kind of way how to do it...via registry edit or smthg like that?.

Nope. It's the bootloader that's blocking you from doing it. You should be able to install languages with the cab sender, but I have no idea. Never done it.

You don't care about the LTE, but your phone is an LTE device, so whether you care or not, still your phone is different from RM-823. You have to wait for your variant or buy a non-LTE phone so you can flash it right away. as far as i know, its not because of the number (eg: rm-823,rm-808), so even if you change the number, no you still can't flash the RM-823 variant. an LTE device require a different driver than RM-823.
ps: and yes, like exiva said, if your variant is out on navifrm, you gonna have to unlocked your bootloader to be able to flash the 7.8 update.

Confirmed CAN NOT!
Cause I tried.

well, so when I flash the same bootloader as 823 has...it would be possible, but if I can't flash it, it is not.
MyOpicWorm - how did you try it and when did you end? What was the problem or error which you got please?
Thanks

Yes it is, but it is also surely GSM mobile, because there are no LTE devices in our country. There is only GSM, so it must be also GSM, that was what I tried to say.
I don't care about it, because I don't need it. Understand?

as far as i know, RM-808 is an LTE phone..if your phone is GSM, it should be RM-823..i dont know, mybe im wrong

If you can change the product code to one of RM-823, then you can flash 823 to 808 and vice versa. On Symbian device, I did a few times. However, I could not find any software which can change the product code for Luma 900 yet.

It would be superb if you find any software which can do it. I also googled and binged many pages, but can't find solution

They are different hardware and it's not possible. nor would you want to really. why are you wanting to do this?

Cause I would like to have my language (0405-Czech) there. And I don't know how to do it.
I downloaded both roms via navifirm, but don't know what now. I also downloaded CAB file, but no chance how to send it to phone. Cab sender says that no update available...so any help please?

You can't install another firmware if it is not suitable for your device.
Upgrade it to 8858 and after you have to install all the updates your language until 8858.

The ATT Lumia does both 3G and LTE.
Even if you could flash the ROM on it, most likely = bricked phone due to different hardware

First of all please search before opening new thread, this question has been asked too many time..you can't yet flashig AT&T phone bcoz no variant support RM-808 as of now. AT&T device has an LTE connection which is different from RM-823 phone. even if you can change the product code, RM-823 variant don't have an LTE driver and will likely brick/no connection for call,sms,online your phone. All you can do right now is wait for RM-808 variant to come out. Nothing can be done.

More than that, while you can't change the product code. It's more than the code, it's the signature checked against the bootloader.

Lumia 640 LTE "we are working with your mobile operator.." problem

Hi guys, I still have a problem with Lumia 640 LTE. When I try to update to windows 10 mobile thru Updrage advisor, I get this message "Lumia 640 LTE "we are working with your mobile operator..". I try to update thru insider app but is impossible to find a build for my device. Obviously I have Windows Phone 8.1 Update 2 15165.177. Now I have a doubt: Is this phone officially supported to get W10M?
