[Q] How to flash RM-823 on my RM-808 - Nokia Lumia 900

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

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

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 want it to ask if i could flash my lumia 710 (t-mobile US) with the RM-809 VAR T-MOBILE BLACK version that appears in navifirm.
my nokia is DLOAD. Would that be a problem?

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?

Not sure about the interchangeable ROMs. But as far as I know Telcel don't sell Lumia 900s that supports LTE.
Heck, not even the iPhone 5 is LTE at the moment. However iPhone 5 can be upgraded to LTE with a software update.

If you have 4G on your screen it is LTE, if you see H is HSPA,
I have a Rogers Lumia 900 LTE from Canada, and I had a lot of connectivity issues, I loaded it with Telcel MX firmware and I can tell you its the best ROM available.
1.- Fixed all Connectivity issues
2.- APN settings, including MMS are automatically detected
3.- Removed all Rogers Branding (Rogers Lumia 900 doesn't have any branding on the exteriors, so after flashing with Telcel ROM its like a new factory unlocked device with no branding at all)
4.- Telcel ROM doesn't have any operator custom preloaded apps
5.- The only thing I was nervous was the disappearance on the LTE logo, but apparently they only replaced LTE and HSPA+II by 4G.
6.- Internet Sharing started working (Didn't work with Rogers Firmware with my current carrier CLARO)
There si another post that mention this:
http://forum.xda-developers.com/showthread.php?t=1905734&page=2
Bottom line, stay with it, it works great!!
thanks alot
Thanks alot for this, I did notice that the telcel rom has no carrier branding, and after reading all your points concerning rogers rom I am definately staying with this one "if its not broke - don't fix it" very helpful post mods feel free to close this thread.
When you changed ROMs, did you run into a signature error? How did you overcome that? It seems some handsets are tied to their specific carrier -- short of upgrading with a same carrier ROM, the update fails with message 'problem with file signature'. or something along those lines.

I have a Rogers phone that is unlocked and being used on Bell and it is flashed with this rom as well. I used Nokia Care Suite and got the rom through the data package manager. It flashed without any problems. There haven't been any updates through Zune yet so I don't know what will happen when 7.8 is released. If it doesn't do the update automatically I'll just update it again through Nokia Care Suite.

Didn't happened anything like that to me, just looked for my RM in Data Package Manager downloaded the latest one and loaded it using Nokia Care Suite
Thanks... glad it at least works for the Rogers devices. I'm guessing there's something added to the AT&T versions which prevent swapping carrier ROMs, even within the same RM group.
I've tried modifying the product code both in the file names and within the files. Still fails with file signature error.

I have the same issue, maybe try flashing it to an earlier ROM from AT&T that doesn't have that limitation?
Doing a field exercise with my unit so it may be awhile before I get to try it myself.
I actually tried that a week ago... rolled AT&T rom back to 8112 (nothing earlier available on NaviFirm list). Same complaint.

[7.8] build 8858 now on Nokia Care Suite

Well here it is, i'm downloading now. Mostly EU and Finland...I'm in AU but going to try finland.

Rm-823 is released AT&T is an rm-808
Sent from my Lumia 900 using XDA Windows Phone 7 App
Has anyone tried installing the 823 onto the 808? i would be curious to know what happens or what the changes are? In a lot of industries, the model changes but the inards don't.
It will not flash the 823 to an 808. You can pick the rom, but when it tries to flash it barfs.
YEah in this case they are different hardware. from what i can figure the RM-823 has the GSM, 3G and HSDPA bands where the RM-808 has the 4G/LTE bands. In most cases Lumias have all radio and enabled by software but not so with the AT&T models.
so there are loads on there now which make me think that they are getting ready for roll out, would be a nice Chrimbo present.
2 Questions, if you see an EU variant for White, will it work with an EU phone? My current is
Type Designator RM-823
Model Name NOKIA Lumia 900
Product Code 059P5N9
Software Version 2175.2503.8779.12301
Next question is looking on xda etc I must be blind, I see lots of people say they are rocking 7.8 but can not how to get to it. Any pointers to a good post would be happily received.
Cheers
Just finished installing Software Version 2175.2905.8858.12480, Finland variant and apart from some confusion with the Finnish language (until I could change it to English) when first starting up it seems to be running fine.
So far all I've tested is connecting WiFi to my wireless network and then wirelessly tethering the phone to my laptop and it all seems to be working as it should.
Will do some more testing of various functions and let you know if there are any problems.
Now to setup my Home screen tiles properly (finally)

Also as long as it's an rm-823 and the country variant has the same bands as your country then your all good. Worst thing that can happen is your reception won't be as good if the variant you flash from does not have the same bands.
If it doesn't work well, just reflash a different one, all good

No. Not even when the RM-808 is out. It HAS to be the at&t version. Rogers won't flash on a at&t RM-808.

successfully updating my 900 to 7.8..mine is from Singtel Singapore..and no..my variant is not out yet..but i just flash it using Sweden variant and all i can say is everything work like a charm.. except theres no Bluetooth file sharing and ringtone maker yet..i think, its unfinished rom @[email protected] using Windows 8 x64.
Ps: anyone getting their Lumia not recognize by the NCS, try this:
1. Install the driver from Programfiles/nokia/nokia care suit/ driver..install everything, be sure for ur x86 or x64.
2. Restart windows.
3. Avoid using any USB 3.0 when connecting ur phone to ur PC/Laptop.
Edit: as i read on some others article, theres someone that said their 7.8 have the Bluetooth file sharing and ringtone maker..and most of them using India variant..but, too lazy to flash again xD anyone care to try? and i dont think theres a big diffrent between variant, well im using Singapore set and successfully flash using Sweden variant, so theres no big diffrent between each other and basically..u can used any variant you like, except if u are on at&t as their Lumias have an LTE which diffrent from all of us
All you need is the windows driver on the root of that drivers directory. I confirmed it today if your system is 64bit install that if it's 32 just install that one.

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.

Install A70F with A70M firmware

Hi,
Is it possible to install A70M firmware on A70F device?
Regards
I don't think so. However I'm not entirely sure. I also have the the A705F. Software updates take longer to arrive. Would be pretty sweet to flash a different countries firmware.
Thx the bro, I will wait for somebody else opinion. The only difference is the bands in each version. If the bands are software related I don't see why will not work.
Anybody else with ideas
