I have got a Nokia Lumia 800 RM-801.
Is it now possible to flash WCDMA 850 Network support onto this model?
I have read a few comments about flashing with Nokia Care Suite and Nokia Data Package manager but no real clear indication of whether or not its possible.
I am using Telstra (australia) and they use the same 850MHz frequency as AT&T. I am unable to find any RM-819 models anywhere.
So long story short, I'll lose my unlimited data if i switch to an LTE device and I really like the Lumia 900, the 800 is basically the 900 minus the LTE (and a smaller screen but whatever) but it also lacks the 3G 850 band.
Has anyone tried this phone stateside on AT&T, and if so did you get alright 3G coverage?
I've been using the UK unbranded Cyan 800 since Jan on AT&T in Seattle. I, too, am not willing to lose my unlimited data plan for $20/mth. Coverage is good. Would really love to have 850 3G coverage though, as the 1900 is spotty. It performs well though.
Do what you can to find an RM-819 device somewhere. You can spend an arm and a leg and get it from MSFT bundled with accy's. Or, you can import one from another country.
Awesome! Now if I could only find what band covers the western New York area I'd be half tempted to sell off my Radar
And thanks for the tip about the RM-819, just checked telus's site and it looks like their 800 supports the 850 band so I might not need to see which band covers my area

I, too, was looking for an RM-819 for a decent price, but I haven't had much trouble with the RM-801 in Austin on AT&T's 3G. Some places where I would normally have 3G, this phone gets EDGE, but that's an acceptable compromise for having this phone.
Just get one off Ebay they have plenty there and some are going for cheap
You can get an RM-801 or RM -819 on Amazon. Amazon doesn't tell you which one is which, but I bought both and returned one of them.
The one labelled "Nokia Lumia 800 black 16GB -FACTORY UNLOCKED" is an RM-801, and it's a German T-Mobile/Vodafone branded phone that has been unlocked. $439.99
The one labelled "Nokia Lumia 800 NK-800 Windows Unlocked Phone-International Version" is an RM-819 and it's an unbranded Puerto Rico variant, which is what I have. $491.88
Try omegacell.com.
They are in Alberta. The guy have quite a réputation. Bought mu rm-801 from Jim. Je do have rm-819 in stock now.
a word of warning
Remember that manufacturers are terrible at providing accurate statistics about their phones. Remember when Nokia's own website said 850 band was include? The same was true for newegg.com and plemix and many others. So regardless of which say 850 band is include understand that they're most likely wrong unless it is in the place of the 900 band. Or it specifically says rm819.
Another note, that htc radar will work on at&t if it is (A) unlocked and (B) the t-mobile usa model. The same is true for the Lumia 710. T-mobile was bad ass about that and included some of at&t's 3g bands.

How I unlock the Lumia 800 from puerto rico locked to Claro?

Just to be explicit here - there are TWO versions of he Lumia 800. RM-801 is the original European release. Microsoft now sells RM-819 in its Microsoft Stores, which adds the AT&T 850 band and does HSPA+ (which shows up on the phone as "4G").
Long story short: US buyers avoid the original model and insist on getting the RM-819 for AT&T use.
wouldnt the lumia 800 custom roms work because its the same phone just th EU version!??
The Lumia 800 is not an EU version of the 900. The 800 is sold in North America as well as other non-European places.
They are similar, but they have some slight hardware differences and use different firmware. Maybe in the future their will be a custom ROM for the 900.
Just wondering if there are any guides out there that I can use to flash my new Vodafone UK branded Lumia 920 to either Telstra or unbranded?
I am with Telstra and the phone correctly supports the 3G and LTE network, but I just want to change it from Vodafone branding
.
Is it the same process as flashing a Lumia 800? Using Nokia CareSuite and if so can someone please post the links to all the software needed?
I would greatly appreciate any feedback. Thanks in advance.

Are you sure you have a Lumia 920? The reason I ask is because a Vodafone UK variant of the 920 doesn't actually exist. The only networks that are selling the 920 in the UK are EE, Orange and T-Mobile.
I'll vouch for it being a 920. I saw the Vodafone Lumia 920 red models on Mobicity a few days ago. I imagine that's what this person got.

Mobicity only sell unlocked and unbranded phones. They don't sell network branded phones or act as a middleman selling contracts for the networks. They 920 they are selling is a SIM free unbranded one for £599.95. As it is at the moment the only networks allowed to sell the 920 in the UK are EE, T-Mobile and Orange.
Hello,
I've read way too many contradicting answers for this question, so I'd like to dedicate a thread just to clarify this once and for all for everyone...hopefully.
The S4 processor has a software-defined radio. Does that mean that there are no variations in hardware (radio) across all Lumia 920s?
And has anyone flashed a Rogers 920 to an unbranded European ROM?
Thanks!
The Lumia 920 american versions identify themselves as RM-820. The EU versions identify themselves as RM-821. Flashing an 820 with an 821-ROM seems not to work though I can't remember on which thread here I read it.
Given that the Rogers variant seems to support the 1700 Mhz AWS band while the EU variants don't I guess that we might be looking at different radio hardware as well but I can't tell you with certainty.
I think someone who can do a teardown would be able to answer. I am not so brave.
