[Nokia Lumia 900] Brazen9000:
Thanks so much for this thread!

I've bricked my lumia 900, battery drained down and didn't use the oem charger to charge. It won't turn on, does that boot loop thing but never gets past the carrier screen.

I thought this thread was my life saver. But the pc won't recognize the connected lumia. I can put the phone into that download mode with the pc on the screen but still no joy. Any tips? I'd really appreciate any help. I could exchange the phone but am out of the country for the next three weeks!
[Nokia Lumia 900] SuperSport:
Did you follow the Video Tutorial and install the Special Nokia Driver? It won't flash without that installed. See it at 5:15 in the video.
[Nokia Lumia 900] dnorthington:
FYI... I seemed to brick mine at first. Then after a number of reflashes (it kept failing after getting about 90% complete), it worked.
[Nokia Lumia 900] fpoon:
Forgive me if this question is stupid, but if we can flash the OEM ROMs even with a locked bootloader, why can't we flash custom ROMs?

I haven't tried to flash mine yet, because I can't use my computer ATM.
[Nokia Lumia 900] pacherecords:
Hi, i´m from Mexico, i never use a Lumia phone, i´m from Android forums hahaha, well in my local version of ebay.com a site named mercadolibre.com.mx, an user sells an At&t locked Lumia 900,is the cheapest lumia phone in the site, i want to know if its possible unlock it to use with my micro sim card from my local operator Telcel, thank you.
[Nokia Lumia 900] SuperSport:
I believe it has something to do with Digital Signatures. They have ones that the phone accepts, and they aren't into sharing... :mad: Their moms should have a talk with them. :p
[Nokia Lumia 900] SuperSport:
I believe people are getting their Lumias unlocked online. You would need to verify if the Lumia uses the same radio frequencies as your provider.
[Nokia Lumia 900] kenikh:
Correct. The signature GUID is the key.

AT&T Lumia 900 is not currently unlockable.
[Nokia Lumia 900] xxxrichievxxx:
Are you telling me that this phone wont be able to be unlocked? D:
[Nokia Lumia 900] xsever:
NO
[Nokia Lumia 900] SuperSport:
I apologize, I had seen Lumias were being unlocked. Just didn't realize the ATT version was not included. :o
[Nokia Lumia 900] awagner:
Looks like a new firmware is on Nokia's server for download, but how do you flash it?

Nevermind... looked new, but same software I had on device
[Nokia Lumia 900] xsever:
How come 2175.1003.8112.12085 is not on Navifirm?
[Nokia Lumia 900] SuperSport:
That is strange... It's available on CareSuite, but not NaviFirm.

EDIT: Ahhh, just figured it out. Clear the Local Cache on NaviFirm, then it comes up.
[Nokia Lumia 900] hkhan1:
internet sharing

A

That is not correct. I have been using captivate with custom Rom and i don't have tethering plan, and i am able to share the internet. I am with At&t with 200mb basic plan.
[Nokia Lumia 900] SuperSport:
I just added an Easy Tango Updater here. You can now run Tango on your ATT Lumia 900.
[Nokia Lumia 900] xxxrichievxxx:
I second this, on my htc hd7s i was able to use the share internet function and i too am on a 200mb basic plan. was able to launch and make my own wifi name and password. worked like a charm
[Nokia Lumia 900] kenikh:
Here's the back story:

Wifi tethering option shows up on all AT&T Lumia 900

If you try to activate it in Settings, you get told to call 611 to activate

If you call 611 and activate, you end up paying for a tethering plan

AT&T sends an OTA patch file to your phone unlocking the tethering

Bing, bang, boom: tethering works

On older phones, there were plenty of hacks to get around the locked down tethering feature. None yet exist for the Lumia 900.

HD7 was so easy to get tethering working, it wasn't even funny. I wish my wife hadn't dropped my Focus in the toilet...I miss free tethering. :(
[Nokia Lumia 900] kmalinich:
That's not true. When internet tethering is activated it connects with a different APN. there's no 'OTA patch file' ... lol. The firmware on the Lumia 900 is hardlocked with requiring the tethering APN to be connected when the Internet Sharing is activated. The only plan that offers access using the tethering plan is the $50 DataPro 5GB plan and the old $45 DataPro 4GB plan. The 'hacks' are allowing the internet sharing to take place using the normal data access APN.

There's still monitoring done on the backend, so if you send/receive traffic usually associated with computers or other devices that a phone cannot send/receive, the crawler that is in place will automatically add the tethering plan, which currently stands at $50 for 5GB.
[Nokia Lumia 900] merocazi:
can unlock the phone nokia lumia 900 of AT & T?
[Nokia Lumia 900] xsever:
No.
[Nokia Lumia 900] fpoon:
One thing I found out is that the ROM is extractable. Using a tool called Universal Extractor, I got hold of the files inside.

The .esco files are just ZIP files, and they have .img files inside them. Hope this helps other developers working on unlock/custom ROM.
[Nokia Lumia 900] TudorBlue:
Windows phones seem to be more trouble than they are worth. I had a play around with a Nokia Lumia 900 and I thought it was very easy to use. My thoughts were full of, how do you hack this phone, jailbreak it or whatever the terminology is for windows 7 phones. Then I read through the Nokia Lumia 900 posts. I have come to this conclusion

1) Android is very easy to root

2) The grass isnt always greener on the other side of the fence

3) I'll stick with my trusty HTC Sensation. :fingers-crossed:
[Nokia Lumia 900] efektos:
Thank you for the useless comment which is not related to this thread... :rolleyes:
[Nokia Lumia 900] xsever:
8779 was announced today by nokia for the lumia 900
[Nokia Lumia 900] TudorBlue:
Silly question BUT what is that exactly? Really noob question. Never really bothered with a windows device but I did like the lumia 900 when I had a play with one.

---------- Post added at 11:52 PM ---------- Previous post was at 11:50 PM ----------

Apologies, it was more of a observation that I hope gets blown out of the water. I do like the look of the Nokia Lumias even though Im an android addict:o

[Nokia Lumia 900] bereda:
wouldnt the lumia 800 custom roms work because its the same phone just th EU version!??
[Nokia Lumia 900] SuperSport:
You can use these tools to download and flash a ROM for your Lumia 800, but do NOT use the ROMs listed on the first page to try to flash to your Lumia 800. The 800 and 900 are completely different phones. They are not interchangeable.

But, like I said, you can use the tools on the first page to download the correct ROM for YOUR 800.
[Nokia Lumia 900] detox8907:
I keep getting this error. Any help? The link in the video doesn't show up for me to install the Nokia Care suite. It goes straight to this error message.
[Nokia Lumia 900] xuninc:
It'd help to know more about the system you're using. Version of Windows? 64-bit or 32-bit? After that we can get into prerequisites and whatever else we can think of to help you narrow down the problem.
[Nokia Lumia 900] detox8907:
Thanks, Windows 7 64 bit
[Nokia Lumia 900] SuperSport:
Sorry I missed this. I have not seen this error, but I would suggest you verify you have .NET 4 installed.

http://www.microsoft.com/en-us/download/details.aspx?id=17851

Other than that, you might want to re-download the file to verify it did not corrupt during downloading.
[Nokia Lumia 900] SuperSport:
UPDATE: To anyone having trouble with Nokia Care Suite, or Data Package Manager, please re-download the latest version on the first post. I believe the old versions will stop working at some point.

Bricked phone

My ATT Lumia 900 Black is kind of bricked as it fits every description described in the link below

Can I flash it with ROM? It usually reboots itself every now and then.. does at affect the process of flashing? Has anybody who had a bricked device flashed to get it to work?

Storage site

Use 4shared.c

Limit is 2gig
[Nokia Lumia 900] SuperSport:
Thank you for the suggestion. At this point, it's probably best for people to use the Data Package Manager to download the latest ROMs themselves. There's now version 12085 available. That way, you will always get the latest version when you check for it.
[Nokia Lumia 900] phonedev_noob:
Any suggestions?
[Nokia Lumia 900] kwill:
Hey Supersport, any chance you can cab up the newest tango w\firmware update for ATT Lumia? Apparently it's listed on Navifirm now! Thanks in advance!

http://www.wpcentral.com/att-lumia-900-os-and-firmware-update-now-nokia’s-servers
[Nokia Lumia 900] SuperSport:
Unfortunately, the version available is only the full ROM, and i don't know of any way to convert that to cab files. The cab files come from the Zune update.

EDIT: You can of course flash the ROM using the tools found in my other thread, but that will reset your phone and you will lose any unsaved data, mms, etc...
[Nokia Lumia 900] kwill:
Ah, I forget the cabs come from the Zune update. Checking out the guide now and may do a full reset just to get it on there anyways. Maybe change over to my outlook.com account while I'm at it.
[Nokia Lumia 900] SuperSport:
There you go, a two fer.
[Nokia Lumia 900] jhollander:
Is there anyway to get the ROM though? Switching to my outlook would at least make it worth the reset.
[Nokia Lumia 900] SuperSport:
Yes, using the tools on the first post, you can download and flash the new ROM to your phone. Follow the video. When you go to download the ROM, you will see the new ones listed.

EDIT: For anyone wondering if it's worth it or not, you can read/watch this review and decide for yourself.

[Nokia Lumia 900] kenikh:
Anyone who forced the update to 8773, you may have to revert to get this to work. Nokia Suite won't communicate with my device due to a signature mismatch.
[Nokia Lumia 900] emenny81:
I had to reset the phone using the programming functions on the nokia suite.
[Nokia Lumia 900] TORQUERULES:
Thanks Supersport! I just used this guide to update to 8779.
[Nokia Lumia 900] SuperSport:
That's great news, thanks for sharing. I've been reading that it's faster and smoother. Did you notice anything?
[Nokia Lumia 900] xsever:
Along with the firmware update, the camera is better, screen is better, flip to silence is there, counters app is nifty, etc...
[Nokia Lumia 900] TORQUERULES:
It IS faster and smoother. I haven't had time to play with the camera to really notice those improvements. The lower buttons are lit all the time with the screen now (finally!).

One weird thing I did notice, is that it takes the phone a little longer than before to notice that I have the USB cable plugged in. I really think that is purposeful on Nokia's end. Maybe to avoid charging spikes? Who knows?

Battery life is as good as before after I let it run completely dry and then recharged (had to do that stock and with 8773 because it seems to reset things...).

---------- Post added at 09:56 AM ---------- Previous post was at 09:53 AM ----------

I haven't had a chance to try the flip to silence. Forgot it was supposed to be there. I have noticed the screen is a little better. I will have to try the counters app.
[Nokia Lumia 900] jhoff80:
Really? Longer than before? Mine already sometimes takes up to 5 seconds to notice that, is that really going to get worse? :eek:

Clearly not a big deal but that'd be weird if the delay is longer.
[Nokia Lumia 900] Screwbal:
So i flashed Tango on my cyan 900 and it works great but I just noticed this so I figure I'll see if anyon else has the same issue. In my me tile if I go to notifications I can't click on any of them. They give the error that it can't be loaded or that I don't have permissions.

Anyone else seeing that?

5 secs in still about it for charge, and for the computer a little longer.
[Nokia Lumia 900] xxxrichievxxx:
My phone detects the charger in about 2 seconds (not like it's a big deal with the delays) The 2 things that I did notice, When I was getting a call; I was unable to slide the menu up to ignore call. it's almost like the phone didnt feel me touching the screen. also the lock screen, most of he times i can unlock the screen by just sliding a bit from bottom to top. but about 5 minutes ago i had to drag the lock screen all the way to the top or else it would be stuck mid way!
[Nokia Lumia 900] aggelosss5:
Hi it is possible to flash another rom from other company to at&t nokia lumia 900
[Nokia Lumia 900] SuperSport:
No, you can only flash the ROM to your phone that matches the Product Code of your Phone.
[Nokia Lumia 900] SuperSport:
I apologize for not answering earlier. I am not sure what is happening, so I was hoping someone who knows would be able to help.

I'm wondering if you are dealing with a possible battery issue also. But if that's not it:

Have you tried to flash your phone using the Restore Option and the Recovery Option? Have you tried both ways?

Have you tried to Restore a Previous Backup, then flash a new ROM?

Also, this page has a LOT of suggestions. Maybe one of them might end up helping.
[Nokia Lumia 900] Demaar:
OK so this is probably a dumb question but I'm asking anyway. I have a Lumia 900 RM-823 from Hong Kong with 2175.2101.8779.12201 installed. Can I flash my phone with the same version firmware but a different country variant, or would that brick it?
[Nokia Lumia 900] aquanaut88:
A little difficult to guess what your question is about. Do you mean the ROM image (823 vs. 808) or a variant of the 823 ROMs? 823 to 808 has been tried but unsuccessful (see SuperSport's posts 2 above this one).

I don't know the answer to the second possibility -- switching from a Nokia Lumia 900 Black (823) to Nokia Lumia 900 Cyan (823). Nor can I guess why someone would want to do this other than out of curiosity.
[Nokia Lumia 900] Demaar:
Sorry yeah, a variant of the 823 roms. I'd just prefer all the default settings and apps to be localised, if possible.

Edit: Giving it a burl. Wish me luck!

Edit 2: Appears to have been successful! The phone formerly had Chinese apps installed by default. Now after flashing it with the Optus variant of the latest RM-823 rom going into App Highlights shows "aussie picks" and language/location settings are defaulted to Australian options. I'll do an update if any problems crop up, but it appears to be safe :)
[Nokia Lumia 900] suchiqaz:
My search of unlocking brought me to this thread. Now can I use this ROM flashing and get my AT&T lumia 900 unlocked? Sorry, with windows 7.5 i am a baby.
[Nokia Lumia 900] Demaar:
From what I've read around (and the reason I ended up buying a pre-unlocked Lumia 900 from Hong Kong) it's not possible to unlock AT&T Lumia 900s and won't be possible for the foreseeable future.
[Nokia Lumia 900] MrPhilo:
Hey mate so you have a RM-823 device and you used the RM-808 to update it? Or you used a similar RM-823 but more updated from another country carrier and updated to that?
[Nokia Lumia 900] denispage:
Can I flash an unlocked AT&T Lumia 900 using another rom?

Why do I need that. I´m using the mobile phone in Brazil and there is no 4g frequency here. When I let the phone in 3g connection, it try to connect in 4g network and there is no 4g network here. This kills the battery in 2 hours.

I would like to try a ROM from some place that doesn´t have the 4g.

Thanks
[Nokia Lumia 900] Demaar:
Sorry about the delayed reply. I used the same RM-823 firmware (right down to the same version number) but selected a different country variant in the Care Suite. The result is a phone running the same firmware but different localisation settings :)

Edit: Also I've been using the phone daily since I did that initial post about the firmware and it's operated in the way I expected it to after 22 months of using my Omnia 7, absolutely zero issues :)
[Nokia Lumia 900] aquanaut88:
Thanks for the follow-up... that's useful feedback for others considering changing locales and using 823 handsets.

Cheers

Hi supersport, i just got my Cyan Lumia 900 but i live outside the U.S so no ATT provider, can i still flash my phone with that tool ? also i have an echo problem; tried all the solutions and none worked still got the echo

Will the rom fix that ?

thx !
[Nokia Lumia 900] xsever:
Anyone getting download error trying to get the latest firmware for Rogers Black?
[Nokia Lumia 900] SuperSport:
I don't believe so.

You can flash the ROM that is designed for your phone, no matter where you live. Flashing MIGHT fix the echo, but it may also be hardware or network related. Worth a try though. Remember, if something goes wrong, it may hurt the phone, although chances are slim. You might see if warranty can do anything for you.

Are you running the latest Package Manager ver 2012.18.0?
[Nokia Lumia 900] xsever:
Yes I am. I even get an error in Nokia Care Suite when the latter tries downloading the firmware.
[Nokia Lumia 900] SuperSport:
I'm not sure what's going wrong, but I'm downloading it for you now. Will post here when complete.

EDIT: Here it is. Due to MediaFire file size restrictions, I had to break it up into 5 parts. Download all the parts, then run the first part, (file with my SuperSport icon), to start extracting it. It's currently uploading, so be sure you get all 5 parts...
[Nokia Lumia 900] xsever:
Thanks a lot for your effort. Can you please double check and tell me in which path I should place the ROM files?

I believe it's C:/Program Data/Nokia/Care Suite/Packages ....
[Nokia Lumia 900] SuperSport:
C:\ProgramData\Nokia\Packages

Although, I believe you can change that to whatever you want using preferences.
[Nokia Lumia 900] xsever:
I used the recovery mode as per your tutorial. The flashing failed giving me this error.

Loading hashblock failed with ‘Messenger nQcountered error ‘ERROR: OSBL reported an error! Code: 0x30056’’

it seems the phone is bricked now as it won't turn on. Only the 3 buttons' lights come up. Screen remains black.

---------- Post added at 08:36 PM ---------- Previous post was at 07:42 PM ----------

Re-downloaded the firmware and did dead-mode flashing and phone is back up and running with latest firmware. Even the OS got updated to the latest 8779.
[Nokia Lumia 900] SuperSport:
Very glad to hear you are going again. Sorry about the scare... I think now may be a good time to remind everyone: The software I link to is from Nokia, and not myself. While it is normally completely safe to use it, one always runs the risk of damaging their phone when using tools like these. So, remember, please use them at your own risk, and be cautious. Backup, Backup, Backup....
[Nokia Lumia 900] xsever:
Thanks for the heads up. I wasn't too worried since I know all about dead flashing and the phone in question was a spare and not my primary one.
[Nokia Lumia 900] SuperSport:
No problem, and again, I'm glad it's going. By the way, notice any differences in performance?

EDIT: One more thing, if you have a moment, can you post how you performed the dead flash so others in your position may benefit in the future? Thank you.
[Nokia Lumia 900] zdentist:
That's a great thread. But I have a quick question is there a way that I can flash a different country variant on the phone other than AT&T as the 800 or not.If so can anybody guide through the process as I have tried several ways(changing RM version in the files prior to flashing but I always get an error.

Thanks in advance for the replies
[Nokia Lumia 900] Razorfold:
I don't think you can due to the different hardware.

The AT&T Lumia has an LTE radio, the international ones don't.
[Nokia Lumia 900] xsever:
Will do. Just been crazy busy lately.
[Nokia Lumia 900] EG8196:
will it remove the provider splash screen?

Thanks
[Nokia Lumia 900] SuperSport:
No, it puts the phone back to it's original state as if you had sent it into Nokia for repair. In other words, stock, but latest available OS, Firmware, etc... But the ATT, Rogers, or ??? specific items will still be there.
[Nokia Lumia 900] SuperSport:
Not sure if you've all seen this, but I'd be curious to know if it's a good replacement for the Suite I've posted on the first post. I downloaded it and ran it, but without my Lumia, I cannot tell much about it. Give it a try and report back if you don't mind...

http://wmpoweruser.com/nokia-suite-...&utm_campaign=Feed:+WmPowerUser+(WMPowerUser)
[Nokia Lumia 900] EG8196:
It couldn't detect my NL900....
[Nokia Lumia 900] SuperSport:
That's strange, as that was the whole reason for the new release. To support the Lumia's. Maybe a driver did not install correctly?
[Nokia Lumia 900] sakenfenc:
Not for the 900 Rm-808

Nokia suite was not designed for the the Lumias if you go to Nokia beta labs website and search it it shows not compatible ..also there is no way to change the usb mode in the Lumia to connect to to the suite!!!

Thanks for trying!!
