    I am on Tmobile and have the Lumia 925. I am considering doing the Nokia Software Recovery Tool rollback. My question is: If I do this, will I get Cyan even though Tmobile has not yet released it? Or is it just not released for those who are on the Developer Preview?

    Has anyone on a Tmobile L925 been successful getting Cyan using the Recovery Tool?

    Thanks!

    Cyan will have to be released for your phone for you to get it. If it's locked to T-Mobile and they haven't released it then you can't get it.

    Once it is released you can use the recovery tool to go straight to Cyan if you want.

    Then what's the advantage to using the Software Recovery tool if you have to wait for Tmobile to release the update anyway?

    You need to flash the ROM to product code: 059T883, variant name: RM-893 VAR LTA MV WHITE using the Nokia Care Suite. That is how you get out from under T-Mobile's holding up the updates. Look at recent threads and the instructions on how to do it are there. It takes about 20 minutes with most of the time is waiting on the ROM to download from Nokia/Microsoft's web site.

    While that WILL get you Cyan on your 925, you will lose any t-mobile specific modifications, such as WiFi Calling, and, uh... not sure what else. But it's supposed to be released sometime this month (October), so if you can wait a couple weeks longer.

    The only thing you lose is WIFI calling. Unless you plan to use WIFI calling overseas it shouldn't be an issue. If you need it at your home or workplace, you really need to be on another carrier which the ROM I listed conveniently works great on AT&T's network also.

    Yes, you can. I would download the T-Mobile ROM just to have it on hand in case something goes wrong, but you shouldn't need it if you download the ROM I mentioned earlier in this thread. There is only 1 T-Mobile ROM for the 925, the WHITE one that says T-Mobile, so it's not hard to figure out.

    Agreed. I reached out to them via Twitter and they told me that their developers are still testing cyan. Really? C'mon AT&T has it for all their devices let soon Denim will be out before we get Cyan. I'm seriously considering going to AT&T and upgrading my wife's phone giving her my unlocked 925 while I get a 1520.

    This might not be the place to ask, but for those of us using an international model 925 (RM-892, TW in my case), is there a way to get the Recovery Tool to restore back to 8.0 after any post-8.1 updates? It only seems to work for 8.1 itself, nothing afterwards--trying to restore just gets you an early version of 8.1.

    I'm a little annoyed about losing internet sharing, and the 8.1 audio playback bug (which is also incorrectable apparently). I've never tried flashing a ROM, so I don't know that that would be the solution.

    You would need to pick an 8.0 ROM from this list and search the Care Suite downloads to see if it's still available...Nokia Product Code Listing for NaviFirm+ Download - (Nokia 530, 636, 638, 930 Added) - GSM-Forum

    Did you actually get dropped calls and/or slower data speeds? Carriers and manufacturers have been known to tweak signal meters to make their signals report better than they are. I suspect you were getting the exact same signal, but the MV WHITE ROM was reporting a more accurate reading than the T_Mo ROM. On I-Phones you can dial *3001#12345#* to get the exact signal reading by db instead of a made up one by the carriers. I wish I did know how to enter test mode to do that on a Windows Phone, if that's even possible. When I first went on the AT&T network and still had the T-Mo ROM loaded, it always showed 5 bars and was very suspicious of the readings, just can't prove it. Now I see anywhere from 3 to 5 bars. That said, since the MV White is a South American ROM, your WIFI signal will read lower. I have seen that myself and it is due to South American routers having double the output power ours do and the ROM looks to have been adjusted for that.

    If I'm not mistaken you will lose Wifi Calling. The principle reason one buys a TMO 925.

    Yeah, like rolling out OTA WFC for the peasant 521 but they couldn't be bothered to do so for the mid-upper range 810. If they had, I wouldn't have waste hundreds of hours of aggravation with 925's. I've been with TMO for twelve years. Mostly happy due to the big Bang for the Buck, great CS, but this **** is inexcusable.

    OTOH, sometimes you just have to bend over and Vaseline is not an option.

    I think the camera, looks, operating system would be way above WIFI calling. If you really need WIFI calling, you really need a different carrier. I was like you and had been with T-Mo for a long time, since 2003. Once I finally had enough with the Cyan crap, I discovered the wonders of being on a real network. It's a whole different world out there. You have reception without the stupid WIFI calling that doesn't work half the time.

    Personally, I'm giving T-Mobile to the end of October to release Cyan. If not I'm flashing a different ROM (probably AT&T) and will leave T-Mobile for good.

    I have to respectfully disagree. The general t-mobile (and roaming) coverage around my area is decent. A lot of 2g coverage, but I lived with sprint for nearly 15 years. However, I live at a secluded lake, where Sprint, Verizon, AT&T, and of course T-Mobile don't have coverage. Staying with t-mobile is really my only option to have "service" at my house...

    Said ROMS are here along with everything your need: http://pgotze01.synology.me:5000/fbd...E&stdhtml=true Said instructions are here: [Tutorial] Unbrand (flash) Nokia Windows Pho€ | Windows Phone 8 Development and Hacking | XDA Forums The only ROM I recommend is this one: product code: 059T883, variant name: RM-893 VAR LTA MV WHITE. I'm sure there are others that work, but it has all the US LTE frequencies and works great. I tried a couple of others that wouldn't flash including the AT&T one. Microsoft lists this as generic for Mexico. Argentina, and some other countries down there also have carriers that use this as primary. If you have trouble with log in to Nokia to get the ROMs, make sure you have replaced the 3 instances of the file in your new Nokia folder with the one you extract from the RAR file.
