Not until the at&t variants are released.

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.

[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.

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

Unlock FDD LTE Band 3 (1800MHZ) on OnePlus 3 US Variant

Is there any way that I can buy the EU\Asia or Chinese variant of OnePlus 3 in US from OnePlus or flash a custom ROM or kernerl to get LTE Band 3 on the US variant?

OnePlus AMA going on over @ Reddit, there is no 32GB model coming.
https://www.reddit.com/r/Android/comments/4o308u/oneplus_ama_oneplus_3dition/
as all three models are sporting the Snapdragon 820 you will most likely find it is a ROM lock to certain bands and so flashing the EU/Asia ROM will open up Band 3, Otherwise CM13.

i am interested in finding this out also?
thank you

It actually might be locked on the Modem side.
Since there were tools to unlock the Bands for OP1, there might some tools coming to do the same for OP3.

Did anybody find a modem file to flash? Or a way to do this?

Tutorial How to view Network/Bands

Hi Everyone,
Many People here want a 100% confirmation of what Bands this phone supports, i am also interested in this. I want to know Both 8gb/12gb band differences. I am currently waiting for the shipment of the 12gb ram version of the phone. I am providing a quick simple guide on how to show/list network bands, Please keep in mind that below is a guide from "ANOTHER PHONE" (screenshots are from a galaxy phone), I am asking for you to follow the same steps and reply with your own screenshots showing the supported bands from both 8gb ram & 12gb ram versions:
Requirements:
1) internet connection
2) Rooted phone
3) Download/Install this app called Network Signal Guru
Follow below steps :
1) Open Network Signal Guru, it will ask for Root access, and 3 permissions, say yes to all
2) Click the menu Button (picture 1 in attachments)
3) Select "Lock Rat" (picture 2 in attachments), this display supported Network type (as shown in Picture 3 in attachments) (WARNING, DO NOT select anything, take a screenshot and press back.
4) Click the menu button and select "Lock Bands" (Picture 4 in attachment)
5) Here you will have three options to select from: GSM, WCDMA, LTE, select one of them and take a screenshot and hit back, do the same for the other ones: WARNING, don't uncheck/touch anything. (pictures 5-9 shows an example each)
This app only works with Qualcomm processors, i am expecting that this guide also works with the Asus Rog Phone 2 (no guarantees)
After you got your screenshots, you can uninstall this app, please reply back showing bands both models support.

can the phone be unlocked to support many LTE bands or it should hardware support also?

So no difference between WW and Tencent radios? I ask this because of the post: https://forum.xda-developers.com/rog-phone-2/help/asus-malaysia-addresses-key-differences-t3961135
They show the bands in their image from the Malaysian site. I was under the impression that the WW ROM exposed a couple of new bands.

Band 28
Hi, I have the ROG 2 tencent version 8/128
Before I flashed the global rom, the phone was able to connect to band 28 fine, so I found this thread to try to get that band 28 re-enabled. ticking the Band 28 option actually enables it again, but when I reboot the phone the settings don't stick. any tips? would like to get the settings to stick then, unroot then relock the bootloader so it's back to factory state. thanks in advance!

Hi could you share tutorial how to flash cn to ww rom?

During initial setup of the phone it updated to firmware 1907.33. I then searched around and followed these steps.
1. Remove Google account from phone
2. Install Asus bootloader unlock tool apk
3. Run Asus bootloader unlock tool and let it wipe the device

People tried to unlock bands at the poco F1, but, there was no success, And people tried a lot

I found the possible files causing the restrictions on LTE and 5G bands, but I have no idea how to modify them to unlock bands.
In the policyman folder, the files:
- china_msim_restrictions.xml
- disable_nsa_mmwave_bands.xml
- lte_feature_restrictions.xml

These files doesn't unlock B20 - this is hardware limitation. Bands are configured to nvitems but on 5G phones many things changed.
But could you please share to me your modem log file so i can list all hardware supported 4G bands to my cacombos.com website? I have here instruction how to get log file: https://mt-tech.fi/en/how-to-get-4g...phone/#Method_for_Qualcomm_Devices_after_2020 and you can send it to: https://cacombos.com/contribute . This help me understand what bands & combinations this device support.

If you change any ROMs from global to China and vice versa won't unlock the bands. This is locked down with hardware, not software. Older Qualcomm devices could unlock bands with Qualcomm tools/programs. This isn't the case with newer models.
