[Q] How do I choose a rom?

I've recently upgraded my 2.2 to 2.3.3 gingerbread, but the phone's identity is now A8181, the international version. I bought the phone as A8182, which would be compatible with North American networks.
How would I choose a ROM to revert to that's compatible with the local networks? And would 2.3.3 still be compatible, even though the phone thinks it's A8182?

Does the network works? Then no problem.
What network are you on, BTW?

no matter what rom you are using, it won't afect the network that you're phone is compatible with because that is built into the hardware. the rom can change what the software tells you but it will work the same as before

I'm with Rogers (canadian), however I haven't had the chance to use 3G as I don't have a data plan, and the phone was bought unlocked. Wifi works, sms works, mms doesn't, but that needs data.
Would this mean that I can use any rom with my phone and not have its functionality changed in any way?
Which rom would be appropriate if my phone was bought in Canada? The phone may have been supported in the past by Telus.

your desire should be able to work with telus or rogers networks in canada. i'm using an australian desire which is a 8183 on fido but i stick to wireless instead of paying for data. however, the 3g frequencies that the 8182 and 8183 use are compatible with canadian carriers.
yes, you can use any desire rom and it won't affect this compatibility because its built into the hardware. whichever rom you use is up to your personal taste, it doesn't matter where you live

Unlocking Rogers Lumia 900 to work on Telus, LTE?

Hi,
i am interested in buying the Rogers Nokia Lumia 900, unlock it with a code, and make it work on Telus.
Questions to those who bought the Nokia Lumia 900 from Rogers:
1) Does the LTE will work on Telus Network?
2) Is the Internet Sharing locked?
3) I figure we can still get the April 16th update when we unlock it?
4) Where did you bought your codes?
Thanks in advance!

not sure for questions 1-3.
4. I bought mine here... www.remotecellunlock.com
for the Rogers Nokia Lumia 900 it was USD$ 8.79 and code was delivered in 35 minutes

1. dont know
2. now this feature is locked.

Thanks guys for your replies.

I see!
Did you receive the Nokia update yesterday/today? It is apparently available!
In what region are you? I am in Québec!
And i find it strange that the internet sharing option is locked out for your phone, did you bought the AT&T or Rogers device?

i m in Newfoundland. Also i m still not receiving any updates. I was buying from ROGERS.

Does anybody got LTE in Montreal, because the higher I got was 4G. Strange or when Rogers says that LTE is deployed in Montreal it's only one cell tower near their shop in downtown ?

Hi I called AT&T International Services at 1-800-335-4685, you can use skype to call for free.. Anyways I asked if they could give me an unlock code if I bought a Lumia 900 to use outside the US.. the CSR said that it is available and asked for IMEI number and email to send the code to.. but I didn't have the IMEI # because I didn't receive my phone yet.. but Can you please try and let me know if it works??
Thanks

Peoples with unlocked phones, were you able to receive the Nokia update yet?
Is your device from Rogers or AT&T?

I have a Rogers Lumia 900, unlocked and using it on Telus. LTE does indeed work and is fast.
As for updates, I'm not sure how that's going to work, especially device specific updates since it's carrier dependant and Telus doesn't have the 900.

I have a couples questions for you:
- After buying the device from Rogers, where did you get your 'Unlock Code'?
- Did you already had a Micro-SIM card or you went to Telus asking for one? and did you have to ask them to change your data plan for the LTE plan or something?
- You have an LTE icon on the phone?
- Is the Internet Sharing feature working?
- Did you have to make special changes to the settings for your LTE connection to work? Changing APN, etc...
- As for the update from Nokia, you tried the Zune trick of dropping and reconnecting your internet connection or something like that?

[Q] Rogers Lumia 900 for use with Fido

I did hit the search button with no definitive answers.
Does the Lumia 900, bought from a Rogers reseller, then unlocked, then used with a Fido Micro-Sim (already working in a Lumia 800) will have Tethering active (or or can be activated) without additional fees (other than paying for a real data plan, which I already have) ?
Fido does not have any LTE activated, am I right? Don't really care, just to clarify.
Can the Rogers-specific apps be uninstalled?
Is the Nokia Network Setup app available and installable (was installable before on my 800, but now says unavailable for my device in the marketplace, but still works on the phone)?
Phone will have Rogers logo on startup and Rogers colors (Red) instead of the Nokia blue? And since there's no generic Rom's (yet), it is not possible (yet) for North America to unbrand it?
On the same subject, would it be possible to flash the rom with a generic one from the RM-823 list, without 'deactivating' the North American bands (and not 'activating' the european bands)?
Are there manual Cab updates for the 900? I have unbranded phones since 2004 and don't want to be dependent on the original carrier for those important updates that may not be considered important for Rogers.
A few questions, but I don't want to buy a $525+ tax device that will not be as likable as my factory unlocked/unbranded Lumia 800.

Not sure I can answer everything but Fido does not have LTE. In fact I don't even think they have 4G. I'm not sure if tethering works or not. Yes the Rogers apps can be removed easily. Yes Rogers logo will be on bootup. Not sure if you can flash unbranded rom yet since we've seen no luck with AT&T model either. Nokia apps will be available for it as per whatever is in the Nokia section of the Marketplace. No their arent any cab updates. There was the last update which was available for all phones to force the missing keyboard update and could be installed by cab files but that's all I've seen since.

Some of my questions were answered in my research.
Thethering is a gray zone. No definitive answers.
Fido = 4G max. No LTE (yet). It may be announced as a back to school promotion a Fido rep told me. But would require a new SIM card which support LTE?
Uninstall Rogers crap = yes.
Nokia Network Setup app, still not available (as per Marketplace) on my 800, which seems to a North-American 'problem' (there's a topic on Nokia suppot on this). This needs to be confirmed or infirmed by someone who can install or update with a North-American Sim.
Branding may be removable if flashed with a generic rom from Europe, if the radio part is not affected by a flash (as with the 800).
Cabs have been seen, so manual updates = yes.

My experiences on Fido with Lumia 900
Hi,
I would love to hear other peoples experiences with the Lumia on Fido. I am going to mention mine below and would love to hear if any others have experienced the same.
First I would like to say I really enjoy the Lumia 900 although I do have some qwirks that I will mention.
As mentioned previously you can remove the Rogers apps since they don't work. The rogers branding does show up on start up which doesn't bother me that much.
What does bother me is that the phone seems to be slower loading data then Samsung Focus I previously used when on the cellular data. When on Wifi the phone is blazing fast.
I did reset the phone with the Fido sim in it as I initially didn't have it in on setup but it still seems slow when browsing in the browser or even in the market places.
On that note my experience is that this phone switches bands quite frequently in places none of my phones have ever done so. For example the Lumia in Toronto near the airport will drop to Edge and I don't remember ever seeing my focus drop to edge near the airport. The lumia in fact will drop to G here in Nova Scotia where I am temporarily working where I never had an issue on my Focus.
This can cause using the data functions on the phone to be frustrating at times. I would love to hear if anyone else has experienced this.
Thank you and please feel free to ask specific questions about using with Fido.
Thank you.

[Q] Has anyone flash Rogers 7.8 rom to AT&T

I have an AT&T Lumia 900 and I noticed that it has only English and Espanol language. I noticed that Rogers' 7.8 Rom is 60MB larger and I guess it will come with Chinese language too.
I wonder if I can flash Rogers' ROM to AT&T Lumia 900? Has anyone try this option?
Flash Rogers' Lumia 900 (RM-808) 2175.2301.9779.12222 (059P7D1) ROM to AT&T Lumia 900 (RM-808) 2175.2301.8779.12223 (059M7R3)

Not sure if this is going to be helpful, but I have an unlocked Lumia 900, which came from Rogers. I updated it on january to 7.8 with zune when Microsoft released the update, but I was annoyed by the fact that internet sharing still didn't work (it was not working on 7.5). After learning that the issue was because a restriction Rogers puts in place, I read that some were having success flashing the TELCEL MX variant ROM with Nokia Care suite to the Rogers Lumia. I tried to do that, but the Nokia Care Suite refused to flash that ROM, since the product code of my phone (Rogers cyan Lumia 900) didn't match the product code of the ROM I was trying to flash. But then I downgraded the phone to 7.5 again using Nokia Care Suite (the corresponding Rogers cyan 7.5 ROM), and while being on 7.5, Nokia Care Suite happily flashed the phone with the TELCEL MX ROM. Then I upgraded to 7.8 with zune. Now Internet Sharing works (and as an added bonus, the phone is unbranded).
Long story short: If you have already upgraded to 7.8 (which I assume you have), then downgrade to your corresponding 7.5 ROM, and then try flashing with Nokia Care Suite the ROM of your preference (as long as the ROM you chose belongs to the same product, RM-808 ROM to a RM-808 phone, or RM-823 to a RM-823 phone). I personally recommend the TELCEL MX LTE variant (for a RM-808 phone), since internet sharing works, and it has the language you are looking for.

Nice find. Unfortunately this works only on the Rogers devices... AT&T version doesn't.

Not sure about the language packs but my ATT branded but unlocked lumia 900 has internet connection sharing working using TMobile sim. I used it for months as my only home internet since Brooklyn NY was on 1900MHZ. I'll need to try if it still works using net 10 ATT sim

Good to know

I thought the AT&T Lumia 900s could only get 2G connections. Very interesting.

Is it possible to extract the language from this Telcel mx Rom ? And send it with cap Sender to att Rom ?

Unlocked Version on T-Mobile and Wifi Calling

Will the unlocked S20 Ultra work with Tmobile Wifi calling?

Hi,
Not sure but here's my history:
Bought an unlocked S9Plus from Samsung, had issues with WiFi calling on tmobile, never got it working.
So when S10 Plus came out I bought the Tmobile version from Samsung, everything works great.
So I just ordered the s20Plus from Samsung but the Tmobile version to make sure all is well with WiFi
and Tmobile's 5G systems. After a month or so I call Tmobile and get it unlocked, so no problem there.
Just safer to get all the Tmobile crap on there to be safe, also no issues with voicemail to text app either.

WIFI calling may not work I've been told. I just ordered a S20 + unlocked that I plan to use on Verizon. I would have gotten the carrier specific except I am buying it out right and would only get $300 trade in on my S10+ unless I used Verizon financing.
I refuse to do that so I went with the unlocked and got my $600 trade in. If I have bad problems I can always send it back and get the branded one.
My concern wasn't WIFI calling or VoLTE I had to make sure Mobile hotspot and MMS will work and I have been told they will.
I don't use the other features, so they don't matter to me.

So I have the unlocked S10 I use on TMobile work's beautiful and the s20 should as well I can even use wifi calling like you questioned which I hope carries over as well but I'm assuming it should I'll know in about 4-5 days

yeah every unlocked phone I have used on Tmobile wifi Volte has always worked, that`s why I stick with Tmobile, ATT sucked for unlocked phones....... except for the pixels, anything else wifi calling and VOLTE would`nt work.

As soon as I put my t-mobile sim in my U1 it re-starts and installs wifi calling feature. Just confirming it does work

Wi-Fi calling usually works on the unlocked Samsung phones, it's the in-dialer video calling that doesn't. Also, T-Mobile's implementation of RCS in the messages app doesn't work with the unlocked phones. It's usually very easy to flash the T-Mobile firmware using Odin on the unlocked model. That way you get all the carrier specific features. Make sure to boot your phone on the unlocked firmware (with the TMO SIM inserted) before you flash over to the carrier specific firmware. It's known to cause issues if you don't.

Do you know if the same thing works for Verizon? In other words, can an unlocked Galaxy S20 be flashed with Verizon firmware in order to enjoy any Verizon specific features, but still enjoy being bootloader unlocked and rooted?

You can't be bootloader unlocked and rooted since Samsung does not allow you to unlock the bootloader in the US for any carrier. If you're referring to Exynos phones, you can't flash those with the US (unlocked or carrier) firmware. For US phones, you can only flash the US unlocked to any of the US carrier firmware or the carrier phones to the US unlocked firmware.
You can find the firmware here: https://forum.xda-developers.com/ga...g986u-g986u1-firmware-links-flashing-t4054629

I heard about this was thinking if I could flash T-Mobile on the unlocked version will it remain unlocked? Or should I just use Google messages RCS

It's a very easy process and it will not "lock" your phone. You can flash back and forth with no issues.
T-Mobile RCS shows users who are on with a blue dot next to the contact name. It is also different than the Google RCS. If you want to use Google RCS, then everyone you message also needs to use Google Messages in order to take advantage of it. It's up to you if you choose to do it, but if you use T-Mobile and your friends and family do too, it might be worth it.
EDIT: Also if your phone is carrier SIM locked, flashing an unlocked firmware will not unlock it for use on other carriers.
