[Q] Custom Rom - Nokia Lumia 900

Is there or will be any custom rom with wp8 for lumia 900 ;

I would highly doubt it, even if bootloader unlocking is realized. WP8 would require writing a new bootloader (UEFI) & possibly new drivers, so it's at least the same effort as porting Android - in fact, even harder, as there is no source code.

I don't really think that technical issue is the main problem (HTC HD2 is an example, it can run many mobile OS). I think the biggest issue is the "extremely dangerous" bootloader of Nokia. No one can hack it (Lumia 710 is jailbroken just because Qualcomn bootloader (for developers) - NOT Nokia DLOAD (the name of Nokia bootloader) - was revealed)

I think that nothing is unhacked ..... they have hacked everything untill now , a dload can stop hacker minds ?
in my opinion , untill summer , we all have wp8 in our nokia 900 ... cause its a perfect phone and will be shame not to have a wp8 device
and its worst for those who give 600-800 euros ( thats the price in Greece from September to January ) .....

Updating Nokia Lumia 710 RM-809 (T-Mobile/Rogers)

Hello all,
So after updating my Lumia 710 from Rogers, in the "About" screen of the Diagnostic Tool I see that I am on FW revision 1600.3007.7740.11465. This is a few versions behind what seems to be the latest version out there for unlocked variants of the phone...
So I found this page:
http://www.wpcentral.com/hack-t-mobile-lumia-710-flash-windows-phone-os-8107-new-firmware
Which claims that they have flashed the latest Indian firmware (8107.12070) for the RM-803 variant of the phone onto the T-Mobile (RM-809) version. However I am somewhat reluctant to try flashing an RM-803 image onto an RM-809, especially due to the fact that they support different 3G bands. What do you guys think?
Alternatively, I can see in Navifirm+ that the latest available image for the RM-809 is the Australian 8107.12050, so that might be a safer choice?
This will be the first time I try to manually update a Windows Phone... So what do you guys think? I really want to update it since there are some GMail syncing issues on the build that I'm running now.
I updated my lumia 710 from rogers (RM-809) with the RM-803 indian rom 12070 with no problems! Nothing is missing and it's now unbranded If you follow this guide it's really simple!
Thanks, Simon!
After reading your post, I gave it a shot and everything seems to be working fine I wonder if we should be seeing any battery life improvements like the Lumia 800 users?
Just something I should mention, though: I unlocked my phone so that I could use it on Wind Mobile, but after going through the flashing process, the phone became locked again so I had to re-enter my unlock code.
I didn't know that it was even possible for a phone to become locked again, after already having been unlocked...
I am thinking about getting a Lumia 710, and I am really surprised that you guys were able to flash a firmware from another RM-### without bricking the phone.
I currently own the X7 (RM659) from the Rogers and I was told not to flash the Belle firmware from the X& (RM707) since the phone will get bricked.
Nonetheless, thanks a lot for the info.
Which software do you use to flash? Phoenix or WP7 requires other tools? Never mind I found the post detailing how to debrand it.
The weird thing is... I tried to downgrade from the Indian (RM-803) 1070 build to the Australian (RM-809) 1050 build, and I wasn't able to...
It seems there is a small battery bug (Diagnostic tool doesn't display battery info) so that's why I tried to install the Australian one instead.
Whenever the next update comes along, I hope I'll be able to switch back to an RM-809 build... It seems like the safe way to go.

Normally you shouldn't... But the only reason I did it is because other people had successfully done it.
Also keep in mind that Symbian phones seem to be a little pickier - you can brick them just by trying to downgrade to the previous OS.
Edit: Well that's weird... My Battery Status randomly started working!
Edit #2: I just remembered I did a battery pull, so that may have had something to do with why it is fixed now...
I never knew it was possible to downgrade the OS for Nokia phones whether it is Symbian or WP.
Would an unlocked T-Mobile Lumia 710 work fine on the Rogers network? Do the GSM bands match?
It would indeed. The RM-809 model supports HSPA 850/1700/1900/2100. So it will work on any of the North American operators. (excluding the cdma operators like Verizon and Sprint, of course)
Actually, I bought my Lumia 710 from Rogers, unlocked it, and I am using it on Wind Mobile now (same hspa band as t-mobile).
Edit: I hope you're right about the downgrading thing, since that would mean that the reason I wasn't able to flash back to RM-809 was because of the fact that it's a downgrade, as opposed to something being messed up on the phone! I guess I'll find out when the next update comes along.
I am 100% sure you cannot downgrade Nokia firmwares without bricking the phone. I read about one method somewhere, but it was very complicated.
If I were you, I wouldn't be worried, now that you have the RM-803 firmware, next time there is an RM-803 update, you should be able to update via Zune/Nokia Suite without having to go through the method you used at the beginning of the post.
Now your phone is an RM-803 so Zune will recognize it as so and update it normally hence the beauty of debranding where you don't have to wait for operators.
Hello guys i'm new to the site.
I want it to ask if i could flash my lumia 710 (t-mobile US) with the RM-809 VAR T-MOBILE BLACK version that appears in navifirm.
my nokia is DLOAD. Would that be a problem?

I was wondering that too.
Also, there's two T_Mobile 8773 fw's listed for each color phone. One appears to have been released 06/04/12. The other 05/29 . What's the differences?

[Q] lumia 900 rm-823 Dload

Hello friends...,
i need to flash a lumia 900, rm-832 without a dload osbl. i can only access rm 808 from the ATF team.
please help!
thanks.
First, this is not an ATF support forum, although we do have at least one ATF developer among our members.
With that said - bootloader-wise, the RM-808 and RM-823 are the same. You can safely use RM-808 mode with the RM-823.
Note that a new release of ATC is expected soon, which will be able to install an unlocked Qualcomm OSBL. It's currently being tested internally. See the "recover/upgrade" thread.

Lumia 900 AT&T Product code 059L6S0 , but RM-823

Dear all,
I have a Lumia AT&T with product code 059L6S0. It is now using custom rom 7.8 by china ( have XapDeployer and WP7 RootTools ). But when I come to Nokia Care suite to check, it display RM-823 ( Product code 059L6S0 must be RM-808 ).
Now, I dont know if my phone already has qualcomm bootloader and how to install another rom to have Facebook and Google in people hub ( China Rom doesnt include these features). If I use NCS to flash a ship rom AT&T from Nokia, will my devices will be relocked again ?
Thank you and best regards.

[GUIDE] About prototype Lumia devices

If you accidently got a prototype Lumia device with an abnormal firmware installed, you can't use Nokia Care Suite to flash it.
Here's the characteristics of a typical Lumia prototype devices:
1. "proto.nokia.com" or "proto.microsoft.com" printed on the screen.
2. "PROTOTYPE, Property of Nokia" or "PROTOTYPE, Property of Microsoft Mobile" and something else engraved on the back cover.
3. IMEI started from 0044.
4. Lots of output info on the splash screen when booting up phone.
5. "Not for Resale" on the bottom left corner when entering OS.
6. Lots of Apps starting from letter "z", such as "zNocenter", "zBattInfo", "zFeedbackHub".
7. App "Field Medic" included.
8. The splash screen is neither Microsoft nor Nokia nor Network Carrier logo.
9. Boot into MMOS directly, in other words, the interface has a Microsoft logo on it, with some info of firmware revision, and the text "Modem offline" or "RF inactive" or something.
10. Boot into Recovery mode directly without pressing Volume Up, in other words, the interface has a white cog and a lightning.
11. Back cover has few opened hole for testing purposes.
What if you got one?
1. If it's finally released on market, you can install retail firmware into it with this command:
thor2 -mode uefiflash -ffufile <path_to_ffu_file> -skip_signature_check -skip_id_check -do_full_nvi_update -do_factory_reset -reboot
This command can be only used on prototype devices.
You can't use flashing command for retail devices on prototype devices and vice versa.
But, please make full emmc dump with dd command before flashing to prevent from flight mode loop because of baseband. If the baseband has serious problems, after you flash retail firmware on a prototype device, you'll get a flight mode loop, and the IMEI is probably started from "86483-".
2. If it's a cancelled device such as McLaren, Honjo, you can't install retail firmware for any similar devices on it.
3. If the prototype device is really early, the specification is probably different from retail device, for example, some earlier Lumia 920 prototype with Windows Phone 7 button doesn't have as much storage space as retail have.
4. Some prototype devices has their defects because of design, for example, Lumia 636 B2 has a defect that you can't recharge your phone directly, or the emmc will get locked to read-only state, because some capacitors that exists on retail devices are missing.
5. Prototype Lumia eMMCs are not as reliable as retail devices. They're really slow when you got them, and it's nearly impossible to make eMMC dump because the low transfer rate. Few of them are easily fried up.
6. Of course, you can salvage a part for your retail device's replacement, for example, the screen with "proto.nokia.com" or "proto.microsoft.com" printed.
7. DO NOT SEND YOUR PROTOTYPE DEVICE TO SERVICE CENTER IF THE MANUFACTURER HADN'T SOLD THEM IN PUBLIC PREVIOUSLY, OR THEY'LL TAKE YOUR PROTOTYPE DEVICE AWAY WITHOUT RETURN AND CHECK THE SOURCE OF YOUR PROTOTYPE DEVICE.
I have a Lumia 930 Prototype, but it was updated to insider firmware and was bricked. How can I fix it? I've never seen before something like your guide. Best regards.

Hi Hikari,
I have "accidentally" got a 950 proto F2. It seems to be running RTM software, i don't have any of these z- apps you list above or field medic.
Are there any issues I should be aware of with these? Can I reset it?
Cheers

I would like to test all the phone functions but the phone isn't recognised by Lumia Phone Test Application (it's know it's a Lumia 950 RM-1104, but won't test it). Do you know how to get LPTA to work with these prototypes or know an alternative method of testing all the phone functions easily?

I have the 1320 now and I think I did a mistake, it was already on a retail firmware but updates failed to install so I flashed to a different FFU using the command in the OP and now... I seem to have lost mass storage mode although WPI says the bootloader is unlocked.
I did make a full dump with Win32DiskImager before flashing the FFU so I do have the SBL3 needed to enable it again so I thought about trying to enable it again using the bootloader unlock option from WPI... Is WPI able to extract the SBL3 from the raw image of the device if I point it towards it for the SBL3 or do I have to first extract the SBL3 myself?

no. . i not sure . i dont know which firmware installed on you phone.
Can you send me compressed file of your backup emmc file?
At the moment. NO SBL3 FOR 1320 .because all 1320 proto flashed retail. We need sbl3 from proto firmware to unlock for retail. If your backup file is prototype. It good

The firmware is retail but the SBL3 was still prototype on it before I messed around with it.
Will send it in a few days when I get back home.

Lumia 550 update

Hello ! Any way to get my Lumia 550 straight to FCU starting from 10586.494? I mean skipping the two steps in the middle (AU and CU). There could be a way using Over the Cable Updater or is there the firmware itself somewhere in the web which I can flash?

Windows 10 Mobile has no planned feature updates past FCU. The latest build should be 15254. Last I checked, the Lumia 550 continues to be supported thru the end of this year. In April, all users running build 15063 were bumped to 15063.1029. My Lumia 830 received that update (despite being shut out of the feature2 branch). You should check for that update first. It would be best to avoid that update on a metered connection.

Yes I know that. I was looking for a way to avoid to get through the annoying process of update from the old November Update (because I had to recover my Lumia with WDRT) and jump straight to FCU. So flashing some FCU firmware or other ways...

There is no way unless you would have someone to dump a custom ROM supporting your device from the 550 somewhere at like version 15063.297 at least or another later supported version if possible. You could always attempt to dump one your self in the event you have to completely Reset with WDRT on that device in the future. But that is up to you...You would need to read up on the Window Phone internals tool and create a custom rom that way.
edit: Actually I just looked and seems certain variants of the 550 have FW revisions all the way up to OS 10.0.10586.494. If you want further than that a custom rom is the only option.
