GUIDE:
As this is a hack, this process will be very similar to the process of flashing a dead Nokia.
1. Search for Device RM-819 on your favourite "firmware download application".
2. Launch Nokia "Product Support Tool For Store 5.0".
3. Select "No Connection" on PST drop down menu.
4. Go File -> Open product -> Select "RM-819".
5. Go Programming -> Recovery.
6. Your recently downloaded firmware should appear on the screen. If not, make sure you have correctly set the "Product" folder and click update list.
7. Make sure that you have removed your screen lock password. (Helps PST to switch phone between modes on restarting, if required).
8. Select your firmware and click start.
9. This should result in an error message.
10. Just follow the error message, Unplug the USB cable->Power down the device(In some cases, it will restart when you remove the cable)->While holding the "Volume up" button, reinsert the cable->Click "Retry".
11. This should start the flashing process, which should result in success.
To Answer the questions:
1. FW to download is "Nokia 800 RM-819 Country Variant Puerto Rico PR Black V1 (059N5J2)". Not sure if you should be using this on cyan.
2. FW Version is 1600.2483.8107.11501
3. Qualcomm did not create a new SOC especially for Nokia, with one frequency gone missing. All the chips are uniform, it just reduces the production cost.
4. Nokia could have implemented a software lock on the frequencies to curb the inter-continent phone sales.
5. Difference between the two: RM-801 is the 900Mhz version of Lumia 800, for Europe, Africa and Asia. And RM-819 is the 850Mhz version of Lumia 800, for Americas.
6.If you are in Europe, Africa, or Asia; Please use RM-801. RM-819 will introduce limitations to your device.
Please backup your data and do it at your own risk, blah blah blah. This will disable high speed data on 900, and enable it on 850.
Feel free to comment and post your results. Good luck!

Test Results:
-All the existing functionality has been retained.
-After 3 discharges, battery capacity still at 1437mAh.
-The Battery capacity shown, may vary with the battery temperature, perfectly normal.
-Big improvement on Cellular data. Network B/W on Rogers 3G jumped from 3-4Mbps to 11-12Mbps. This means High speed is working.
Doubts:
According to some speculations by "fshqbizfs", it still does not enable 850. (Thank you).
After looking into the Nokia RM-801 Schematics, I found out that, even though the SoC can support 850, Nokia RF circuit is limited to not support 850 Mhz. I believe that my "H" symbol and higher speed, was a mere coincidence. I guess 850 will never work, unless we swap the RF circuit out.
In the end, this becomes a really long way of installing firmware from a different Device. O Well!
***Reserved***
Really interested how the charging works out - can you let us know how the battery performs?? Does the max charge capacity drop down to ~1300mAh after a few days usage?
Thanks
Can't wait!!!!!
Great news! Thanks for your efforts.
Wow, I look forward to your findings!
I've been waiting for a 3G 850mhz Lumia 800 for ages!!

Good news but I'm very sceptical. I would like to see how it will evolve after some charge cycles!
With 11501's firmware all is good but it decreased after one or two battery charges...

Exactly same position as you. On Telstra in Brisbane.
Where is the RM-819 firmware? I'm going rural for 2 weeks and will definitely need this!
Edit: I refreshed NaviFirm and there it is! Awesome!
Very interesting!!
Just noticed NOKIA Lumia 800 (RM-819) firmware available in Navifirm Plus.
Just to confirm, you flashed
"Nokia 800 RM-819 Country Variant Puerto Rico PR Black V1 (059N5J2)"?
I'm tempted to flash this one onto my EU Lumia 800. Will be interested in your continued observations.
I'm certainly sceptical about this having any effect on the 850/900 thing. If it was down to software, Nokia wouldn't have needed to release a new model, they'd have enabled all frequencies from the off.
Take the Nexus One for example, two versions were released, one 850, one 900. The software was identical, same ROM, same baseband firmware. Only difference was the BB chip.

Nokia has been dealing with pentaband for quite a while. It's quite possible the chip does 850 and 900 even though it's Qualcomm.
Why do they lock 850/900 depending on region? Quite simple: carriers. Carriers would much prefer if the users can't switch to competitors in their country. Example: Telstra->Optus.
Why does it have a different RM-#? I'm not sure.
That would make sense for branded phones, but not the SIM free ones that sell worldwide.
What are the software versions (os and firmware) of this firmware? 8107 and 11501? Thnx
I'm waiting for the guide to flash and see by myself!
Anxiously waiting I don't care too much about the battery, but want to see if the extra frequency will improve my AT&T 3G.
I see a North America US variant on Navifirm

In the case of Lumia 800 things are a little different.
It uses the MSM8255 chip, that supports only three active 3G bands, but they are configurable.
So, to enable 850mhz they had to resubmit the phone to FCC with different bands enabled and the 2100 band switched off.
However, they also changed configuration of other components so, even if it works flashing RM-801 with RM-819 firmware, reception will be sub-par comparing with the original RM-819.
You can read what's different here, in the first document of the list.
I quote
"The WCDMA VIII band of RM-801 has been changed to WCDMA V in RM-819. The TX SAW filter, RF power
amplifier and duplexer (WCDMA VIII vs V) are different. The antenna circuit with RF front end has not been
changed. Otherwise the devices are identical."
Ok, just flashed the RM819 firmware to my Deutschland 801. I downloaded the NAM US variant FW from Navifirm. Renamed product code in filenames to the correct one and flashed with Care Suite. Don't notice any difference in data speed. Guess AT&T really do suck in NYC ;P

Data speeds with AT&T at my home depend on the time of day. During the day, I get standard 200KBps or so (Bps, not bps) and at night I can get up to 1.5MBps.
So, are you in a situation where you're able to differentiate between bands, or do I need to flash mine with RM-819? I'll know immediately if it works.
Post #1 updated.
sorry but what is the difference between RM-801 and RM-819 ??
Hello All,
I have just purchased a Lumia 920 RED. On the box it says Nokia 920.1 CV FR Rouge.
It then says GSM & WCDMA and a load of frequencies.
Will this support LTE for internet (if my provider supports LTE of course).
Thanks for your comments.
Nicholas Cross
Since no-one has answered, I sent an e-mail directly to Nokia. Here is the response that they sent. It answers the question very nicely.
Thank you for contacting us with your concern.
This is in reference to your email to us asking about the support of the Nokia Lumia 920 to LTE (Long-Term Evolution or 4G network). We are more than happy to assist you on this.
In response to your concern, please be advised that all Nokia Lumia 920s support 2G, 3G and 4G network/LTE. This means that the phone can be used with the fastest network connection yet. This, however, will depend on the network provider you will be using your phone with. For example, if your current network provider do not support 4G network, the device's LTE capability will not be utilised and 3G network will be used.
To confirm this issue, we suggest that you contact your network provider and ask them if they do offer 4G network as the phone supports it indeed.
Looks like you got the European model.
The EU model has different LTE frequencies than the American one.
So depending in what country you will be using this device and what provider, the phone may support or not 3G and/or 4GLTE.

Thanks for the response. Yes, I have the European version (since I live in Luxembourg). My question wasn't really whether it would get 3G here because of maybe not being on the right frequency, but whether it would get LTE since it didn't mention LTE on the box at all.
I have updated the rom a new version that the Nokia Care Suite found, and now it seems to have changed something because now it often shows that it is connecting as H+. I also asked my phone provider if they offer LTE on standard contracts, and they told me that they don't (for the moment) offer LTE on voice contracts. They only offer it on data ONLY contracts, so for the moment this means that H+ is the best that I can get.
So far, I am impressed with the device, but I am slightly concerned with the battery life. It doesn't seem to be as good as the HTC 7 Pro that I had before, and my wife's Lumia 900 also seems to get better battery life.
The device is new, so it could be that the battery needs "conditioning". Will see how things go.
Have a good weekend!!

CV FR means Country Variant France, so you got the french version. german, french an belgium version should all support LTE 800/900/1800/2100/2600 so you will be fine (luxembourg uses 900/1800). i don't think there exists a version of the NL920 without LTE, but you can easily check it. go to settings -> mobile network and see what you can choose for highest connection speed. there should be 3 options, 2G/3G/4G (with the old Firmware it was LTE instead of 4G)

Orange? They will offer LTE for voice contracts as soon as they get VoLTE ready. sometime in Q1 2013 if i remember correctly.
Thanks for the info regarding VoLTE!!
I had already checked the network settings, and that was why I was concerned. On my phone, it only offered 2G and 3G!!
I have since updated (using the Nokia Suite) the rom, and now the 4G option is there, and I have also seen the H+ symbol show on my data connection.
my only concern now is the battery life, and that seems to be MUCH better with the new rom.
have a great weekend.
I have a Lumia 920 unlocked German version which brought support for the 4G setting from release. I recently flashed it to the Austrian ROM given that I live in Austria. That removed the 4G option. Last friday I then decided to flash the phone to Portico as I hadn't had that much data added to it and that restored the 4G option.
This is in line with what Nokia had been communicating for some time: all Lumia 920 devices have LTE hardware on board but it is not enabled on all pending a future software update. With Portico this now seems to be the case. H+ has been working nicely for me even with the 3G only ROMs which makes sense given that it is just a faster transfer mode on top of UMTS.
I couldn't try out LTE yet as my carrier only has it operational in some locations quite some distance from my home. Therefore I currently have limited it to 3G to avoid the phone looking for an LTE network all the time.
I bought a Lumia 920 from EE which i have unlocked and using with my Three (3) simcard.
I've been unsuccessful in downloading or finding Three (3) UK firmware for this phone. I want to flash it because MMS doesn't appear to work and data speeds appear to be poor on the EE firmware.
Any ideas?

data speeds are slow becuase your model does not support the frequency your provider is using. There are as of last count two version of the 920 and they apparently have different hardware radios. So just flashing may not fix your problem.

Thanks for this. Silly question but is this ok to flash if my phone is white?
I originally bought a PAYG Lumia 920 from EE in Dec 2012. I got it unlocked and used it with my Three SIM and had no problems. My SIM only contract came up for renewal in April and Three offered me a new Lumia 920 on the One Plan for £25 a month and no upfront charge for the phone. I sold my original Lumia and went for the deal making a profit overall. It came with Three firmware, obviously, and again no problem. I since upgraded the firmware to the generic Australian 1314 version and still everything works fine. Three have since unlocked the phone for me at a cost of £15.
I don't see that the specific Three firmware will help particularly, but I have it if you still want to go ahead. You can also follow one of the numerous guides on wpcentral.com and use the Nokia Care Suite to download and install the firmware as long as you have access to Windows. The product code for the Three Lumia 920 is 059R7Z3.
Might be worth downloading the Lumia Pusher app which lets you ensure you have the latest Nokia utilities installed, like Network+ and Access Point.
The only difference between the firmwares for different colour phones is the default colour scheme - for instance, if you have a red Lumia 920 the 'red' firmware will set up the default accent colour to red. Makes no other difference at all. You can easily do this step manually.
I changed my Lumia housing from black to red and made no change to the firmware, just selected red for my colour scheme.
Thanks for the helpful reply.
I flashed both Three UK rom and generic and didn't notice a difference in data speeds so ive decided to stick with generic incase Three UK have long delays in pushing updated firmware.
Guys
New to this forum and need a bit of advice pretty quickly please.
I have been looking for a gear s for a couple of months now.
I am in Hong kong airport right now and they have them in one of the retail outlets.
Problem is I travel quite a bit between UK, Canada and Australia.
If I buy this watch here will I be able to use it in these countrys with different sims ( I have a different sim for each country with voice and data).
Your quick response would bevery much appreciated
You can't use it in Canada, US, Mexico because of the different frequency bands that non-US version doesn't support. Australia uses a mixture of North America frequency (mainly 850MHz) and rest of world frequency (900/1800MHz) bands. So, depends which band your particular Australia carrier uses, it may or may not work.
Gear S is not a true world phone due to its dual-band limitation.
I need a little help with customizations. I know that there isn't big differences between customizations, just bloatware and baseband version. I want the best customization for my country and operator. I live in Hungary and my operator is T-Mobile and my phone is from Hong Kong and now I use Nordic Combined. Then what cust should I use? customized HK or T-Mobile HU or what?
no difference aside radio adaptations for each carrier or country and also the bloat
as far as i know
