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!

[Nokia Lumia 800] tjramage:
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 :)
[Nokia Lumia 800] anseio:
Can't wait!!!!!
[Nokia Lumia 800] dr1337:
Great news! Thanks for your efforts.
[Nokia Lumia 800] wutang01:
Wow, I look forward to your findings!

I've been waiting for a 3G 850mhz Lumia 800 for ages!! :D
[Nokia Lumia 800] MickyMax:
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... :rolleyes:
[Nokia Lumia 800] xsacha:
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!
[Nokia Lumia 800] geekaren:
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.
[Nokia Lumia 800] Rusty!:
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 Lumia 800] xsacha:
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.
[Nokia Lumia 800] Rusty!:
That would make sense for branded phones, but not the SIM free ones that sell worldwide.
[Nokia Lumia 800] Briefcase:
What are the software versions (os and firmware) of this firmware? 8107 and 11501? Thnx
[Nokia Lumia 800] MickyMax:
I'm waiting for the guide to flash and see by myself! ;)
[Nokia Lumia 800] Itaintrite:
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 :D
[Nokia Lumia 800] fshqbizfs:
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."
[Nokia Lumia 800] Itaintrite:
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
[Nokia Lumia 800] anseio:
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.
[Nokia Lumia 800] dk_iceman:
sorry but what is the difference between RM-801 and RM-819 ??
[Nokia Lumia 800] thesmartguyy:
RM-801 is the 900Mhz version of Lumia 800, for Europe, Africa and Asia.

RM-819 is the 850Mhz version of Lumia 800, for Americas.
[Nokia Lumia 800] fshqbizfs:
Dk_iceman read my post above
[Nokia Lumia 800] MickyMax:
"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."

So you don't recommend to flash this firmware if not in US?

If I'm in Europe should I flash this?

Thanks for you guide and explanations :)
[Nokia Lumia 800] thesmartguyy:
If you are in Europe, Africa, or Asia; Please use RM-801. RM-819 will introduce limitations to your device.

Oh bugger, an extra page.
[Nokia Lumia 800] fshqbizfs:
Does NOT work

Just to spare some time to people trying to flash the RM-801 with RM-819: simply, does not work.

It flashes correctly, but 850mhz band is not enabled.

Tested in Mexico with Telcel, that is a "850mhz 3G ONLY" carrier.
[Nokia Lumia 800] thesmartguyy:
Rogers Canada uses 850Mhz and it has been working for me. Are you sure you have 3G coverage in your area?
[Nokia Lumia 800] fshqbizfs:
Rogers also has 1900mhz towers, you are probably getting signal from there.

Telcel only has 850mhz towers, and yes, I have 3G signal on my other phone.

So, sadly, it does not work.
[Nokia Lumia 800] thesmartguyy:
Mexico Telcel uses 850/1900(HSPA)

One of the many sources: http://en.wikipedia.org/wiki/Telcel

Sad to hear that it doesn't work for you.
[Nokia Lumia 800] fshqbizfs:
1) Telcel does not use 1900mhz, it does have only a few towers in touristic places like Cancun, because a lot of americans and europeans come there with their 850mhz-less phones.

2) I don't think it does not work "for me". It does not work at all.
[Nokia Lumia 800] thesmartguyy:
Well, not to get into an argument. My phone used to show only "3G" symbol on top and used to max out at 3Mbps, but now, it shows "H" on top and is pushing 11-12Mbps.
[Nokia Lumia 800] anseio:
I will be able to make a confirmation as soon as I'm done downloading the original firmware as a backup plan. I need to know I can get back to square one with ease.

Since May 2010, I've been using the Nokia 6700 classic (WCDMA 900/1900/2100). It had fantastic signal in my apartment and I was able to USB tether w/o issue. Just under a year ago, when HSPA+ rolled out, I was no longer able to keep a signal for tethering. It was constantly dropping signal to 2G. I thought it was the phone, so I replaced it and had the same problem... only able to maintain 3G when the phone was at the window.

In October, I switched to Telstra HTC HD2 (850MHz). I was able to set the phone by my laptop and tether w/o signal dropping or any issues at all. Now that I have my UK Cyan Lumia 800, I'm back to the same signal issues with the phone setting on my table. So, I constantly switch down to E to keep it from searching/switching/dropping all the time.

Once I've successfully flashed Cyan RM-819, I'll know immediately if it works.
[Nokia Lumia 800] Itaintrite:
Mine shows H all the time even with 801 firmware... speed still crap.
[Nokia Lumia 800] thesmartguyy:
I normally speedtest at night. During the day, its always at 2-3Mbps.
[Nokia Lumia 800] anseio:
I'm at a total loss. I cannot get it into USB flashing mode whatsoever. In Device Manager there's the yellow icon on the Lumia 800 while PST is open. I follow the instructions on the error message after starting recovery and it will not flash the software.

I'm sure something is going wrong in my process. I've never had an easy time flashing Nokia phones.
[Nokia Lumia 800] thesmartguyy:
Don't bother. Post #1 updated

[Nokia Lumia 800] Itaintrite:
Have you installed Zune?
[Nokia Lumia 800] geekaren:
This thread has been helpful to those of us who've been wondering whether our 800s could be flashed to support 850 band.

Thank you for the time you've spent testing and sharing your findings. It has been beneficial, and I'm sure I'm not the only one who appreciates it!
[Nokia Lumia 800] anseio:
I appear to have the connectivity issue fixed. Had to manually install the driver package.

I'm going to give it a go anyway.

---------- Post added at 03:04 PM ---------- Previous post was at 02:15 PM ----------

Sad news:

Accidentally downloaded Magenta RM-819 instead of Cyan, so I installed it anyway. No 850 enabling. Same signal issues when running 3G enabled. Darn.
[Nokia Lumia 800] thesmartguyy:
Thank you :). Glad to be of help.
[Nokia Lumia 800] fshqbizfs:
That is, game over. On a positive note, I guess that now we all have an excuse with our partner\parents\wife to buy the Lumia 900 when it comes out the 18 of March.
[Nokia Lumia 800] anseio:
Hahaha

I'm not sure yet. Looks like the 900 doesn't have the sexy curved glass. I also kinda like the smaller size. Will know for sure when it comes out and I can get my hands on it.
[Nokia Lumia 800] ricky119:
Any Telstra users in Australia tested the RM-819 FW?
[Nokia Lumia 800] anseio:
I don't think it's going to matter.
[Nokia Lumia 800] ricky119:
I saw the new RM-819 FW came out for Australia

Nokia 800 Country Variant Australia AU Matt Black RETAIL (059N6L8)

Nokia 800 RM-819 Telstra Australia AU Matt Black V1 RETAIL MODE (059N6L9)
[Nokia Lumia 800] wutang01:
Where did you see them listed? They don't appear in Navifirm+?
[Nokia Lumia 800] ricky119:
u need to clear the cache first and refresh again, then u will see the new FW
[Nokia Lumia 800] wutang01:
Sorry. I should've waited another 5 minutes. It's come up this time.

Thanks :)
[Nokia Lumia 800] ricky119:
Let me know ur test result, im currently out of AU and cant test the Telstra network

Hopefully the Telstra FW can enable the 850mhz band

Nokia 800 RM-819 Telstra Australia AU Matt Black V1 RETAIL MODE (059N6L9)
[Nokia Lumia 800] anseio:
2 out of 2 tests have confirmed that RM-819 FW will not enable the 850 band. Curious to see how a 3rd performs.

The OP used the Puerto Rico Black FW and I used the North America Magenta and Black FW's.
[Nokia Lumia 800] wutang01:
And I won't be able to either. Just found out my sister took the phone (she's with Optus)!

But anyway, if the reason why it won't work is because of circuitry/voltage (forgive my ignorace, if you detected it) then I don't see it as technically feasible. Someone, feel free to prove me wrong :P
[Nokia Lumia 800] dr1337:
OK, so I'm going to flash the firmware. Only problem is that I don't have a Telstra SIM!
[Nokia Lumia 800] Itaintrite:
I'm having issues with AT&T 3G service.. It's weird. IE works fine but certain apps load really slowly. Time to go back to 801 it seems.
[Nokia Lumia 800] ricky119:
sigh, it seems only flash FW cant enable 850 mhz

hopefully someone can find a way to let RM-801 user to using 850 mhz
[Nokia Lumia 800] Rusty!:
I have a way. Sell RM-801, use proceeds to purchase RM-819.

That's gonna be the only option.
[Nokia Lumia 800] gtg465x:
If the RM-819 only comes as a $900 bundle at Microsoft stores, most of us in the States will probably go for the 900 if we choose to sell our current Lumia 800. Would be a bit ridiculous to spend a ton of money just to get support for the 850 band when 1900 is sufficient most of the time.
[Nokia Lumia 800] ricky119:
I can see more and more RM-819 ROMs are out

Is there someway we can hack or tweak the RM-801 to enable the 850mhz, i really need it on my RM-801
[Nokia Lumia 800] Rusty!:
Not going to happen.
[Nokia Lumia 800] wm.andrew.wilson:
I am curious if someone with the 819 firmware can check if the HSDPA+ toggle in the Nokia Diagnostics app (under settings) actually works now?
[Nokia Lumia 800] anseio:
It does not. I tried it when I had 819 installed.

Nokia Diagnostics is not meant to be a tool with which to manage your phone. It's intended for servicers.
[Nokia Lumia 800] dannejanne:
People need to stop relying on the diagnostics tool. Nokia made a big mistake letting customers easliy getting access to it. All some seems to do is stare at mAh numbers for the battery and such...

You can't do anyting with the tool and apply it to the phone it's just there for testing purposes and might not report exact correct figures for everyting such as the battery.

A lot of the battery issues are from people staring at those numbers thinking their phone is affected because the full charge capacity shrinks over time when in face it does not when it comes to real battery life.
[Nokia Lumia 800] wutang01:
My sister seems to claim that the battery life improved after she removed the diagnostics tool. I can't confirm or deny. Yet!
[Nokia Lumia 800] thesmartguyy:
The RF chip is not compatible with 850 UMTS, but only with 850 GSM.
[Nokia Lumia 800] tjramage:
When on 11451, I can reach ~1300mAh at a full charge. On the same phone, after updating to 11501, the phone reports a battery charge of 86%. This proves that the update 'unlocks' a portion of battery charge which is not available to the phone when using 11451.

Incidentally, the diagnostics app reports a charge of ~1470mAh at 100%, after updating to 11501. However, after a few days, that full charge yet again drops back down to ~1300mAh.

I believe there is a firmware bug with these devices which affects the battery charge. It may only be a ~150mAh, but a 10% loss is a lot to me...
[Nokia Lumia 800] MickyMax:
I think it's a simple coincidence.
[Nokia Lumia 800] aramadsanar:

Lumia 801 & ATT 3g

I have a Question, i know you guys have tested and stated that flashing, the 819On to the 801, will not enable the 850, I have an 801 and i am on straight talk (ATT) so most of the time, So i get H or E on my phone, where i am located its Edge, when i got to the city i get an H, which is great. The problem with Edge on ATT is that when your on the internet or using any kind of data and you get a call it will not come through, it will go straight too voicemail. Now to get on 3g i need the 850 on the phone enabled, which has been stated, that it can not be done. I have noticed sometimes on my phone, when i am at home or certain areas it will show a 3g symbol on my phone. Based on the conclusion of the thread, i should not get 3g on ATT with 801. I have not flashed the 819 to my phone. Anyone have any idea why this may be happening...
[Nokia Lumia 800] anseio:
The technologies are this:

2G services are GPRS (G) and EDGE (E).

3G services are UMTS (3G) and HSPA/HSPA+ (H). *On AT&T branded devices, the HSPA/HSPA+ is actually 'mislabeled' as 4G. It's a marketing gimmick.

Anyway. When your phone is set to E for the highest data connection, it will get GPRS or EDGE, whichever is available; but GPRS only when EDGE cannot be connected. The same for the 3G. Your device will grab onto 3G (UMTS) only when it cannot keep enough of H, but has enough to not drop down to E.
[Nokia Lumia 800] grigsby1:
Thats the Question, The understanding that i get is that the 801. Is not able to the connect to the 3G band of ATT only the 819. And My highest setting on my phone is 3g, not H. ATT 3g is heavy in my Area.
[Nokia Lumia 800] anseio:
RM-801 = GSM 850/900/1800/1900 and WCMDA 900/1900/2100

RM-819 = GSM 850/900/1800/1900 and WCMDA 850/1900/2100

GSM grants you GPRS and EDGE for the data connection (G and E icons).

WCMDA gives you UMTS and HSPA data (3G and H icons).

The icons on your notification are just indicators of the signal being connected. We could label them A, B, C, and D and they'd still mean the same thing. The 3G icon means that you're getting a weak connection on WCMDA 1900MHz, whereas a better connection would yield the H icon for HSPA on the same band.

Make better sense now?
[Nokia Lumia 800] grigsby1:
anseio: I understand now. Thanks.

Hi all

I have a RM801 Lumia that came with the 12070 build and the new Nokia bootloder. If I flash the RM 819 ROM build 11501 as described in the OP, will this downgrade the bootloader to the Qualcomm one?
[Nokia Lumia 800] patrick_dube:
RM-801 radio + RM-819 OS

In the same subject, would it be possible to use the radio ROM from the RM-801 and use the OS rom from the RM-819 to flash a rm-801 device?

This may be useful for people with rm-801 devices in NA, who want to keep te bands intact but change the OS customizations to match their location? Or I missed the post where somebody specifically tested that the bands are unaffected by the flash? Like me, I travel a quite a bit to Europe, so I'm happy to get blazing fast web on my device but would like to get local customizations (if any).

Thanks!

It may be that your phone is not sleeping with the display off in some circumstances.

Probably all those background apps waking it up to check internet for updates.

You need to post your actual display on time also.

My battery life has suddenly dropped too since EL29. I updated and everything was great for a few days. One day I woke up and my battery was draining at about 10% an hour with no use. I've tried rebooting and it seemed to help a little but I'm still dropping at about 6% an hour where before update it was 3% an hour. No idea what's causing it and it was really odd how it came out of nowhere.

Stop using a nonsense app that does no good to your phone. Who in the world need anti-virus app for android. An't no hacker would spend time to come up with a virus that will steal your info. Some apps claim to do this and that but is just all BS. All you need is an app killer and that's it. If you have an app that is continue running ( other than the one require ) than of course is gonna drain the hell out of your battery and it will get hot.
