[Q] How to deBRAND HTC Mozart from T-Mobile?

I have HTC Mozart with latest MANGO update from ZUNE!!
It is from Germany, T-MOBILE with all their apps and addons I don't need here in Bosnia!!! BTW, it SIM Unlocked!!!
How, if possible, to make it run with ORIGINAL HTC WP7.5 Mango!!!???
I searched for T-Mobile MANGO ROM but it nowhere to be found,
all I have available on NET is older ROMS from T-Mobile but I am afraid to BRICK my device if I try DOWNGRADING it from Mango to older BOOTS such as 1.28 or 1.30!
Any solution to this, I would appreciate your help!!!

The capital letters and explamation marks don't actually make it easier to help you, BTW.
If you're trying to de-brand the phone, why would you want a T-Mobile-branded ROM? You just want a stock HTC ROM. It has to be for the correct phone, but tht's about it.
If your bootloader (SPL) is already on version 5, you may have a problem replacing the ROM. If you're on 4.5 or lower, you should be able to flash any official ROM without damaging the device.

ok, thanks

Hey all,
First of all I want to say I am glad that I found this forum and community. I think you really can help me out with my (futher) questions.
Since my Telekom branded HTC Mozart won't get the tethering update I am on the search to debrand my HTC Mozart.
I already read that it is essential to have the right SPL Version, now when I enter the bootloader mode I get following data:
PD67100
SPL-4.5.XXXX.X
Now I have a few Questions:
1. Do I need to check other data before starting to debrand the Phone?​2. Will I get further Updates via ZUNE after I debranded my Phone?​3. What are the main reasons to
a. leave it branded?
b. debrand the Phone?​4. Are there some issues with apps form the Marketplace after the debrand?​
And last but not least:
5. Where can I find a working debranded ROM?​
I would really be thankful for any kind of hints and help
Best regards

@WPeter7:
1) Well, you need to make sure that you're getting an unbranded (open market) ROM, and you need to make sure that your ROM matches your hardware. You also need to back up pictures/movies/music/whatever if you have any on the phone that aren't already on the PC.
2) Yes, official ROMs will continue to receive updates.
3) Leaving it branded lets you access carrier-specific features, like TMO's MyAccount app. It also is simply les hassle, and you don't have to lose all your data (which will hppen if you flash a ROM). Unbranding the phone means you remove all carrier customizations, and may receive updates earlier (because the carrier doesn't need to test and customize them).
4) No, not if it's an official ROM and the region is correct (i.e. if you can access apps now and you use the same primary WLID, you'll be able to access them again). However, you'll probably lose access to carrier-specific apps, as mentioned above.
5) Go look in the forum or wiki section specific to your phone. There should be a list of official ROMs. Alternatively, check this thread: http://forum.xda-developers.com/showthread.php?t=1254384

[Q] Help reverting to original rom

Hi people,
I've tried searching for an answer to my problem but had no luck...
I'm new to wp7. I've just bought a htc mozart on the internet and after receiving it I realized it was originally a telstra (au) model but it is now running Mango 7714.WM7_Main(DFT). I knew nothing about wp7 roms or jailbreak. I realize now this is a custom unbranded mango rom. I wanna revert to the original telstra rom and then update officially to the carrier's mango. I've searched and found this thread with branded roms for the mozart: http://forum.xda-developers.com/showthread.php?t=915827
I use mac and not pc. Is it safe to install a branded nodo rom on my mango DFT mozart? If so, how do I do this on my mac? Can I unlock my mozart later with no problems?

anyone there?

It's safe to do so, yes. However, the flashing tool is written or Windows. You can borrow a friend's Windows system to do it, install Windows on your Mac (directly or in a VM), or try using wine (Win32 compatibility software for POSIX systems, including OS X) to run the flashing tool. I don't know which of these is easiest; it's probably not Wine but that's the only one that doesn't require somebody having a copy of Windows (Wine is free and open-source; http://winehq.org).
As for "unlock" that really depends what you mean.
If you want to developer-unlock it, using an AppHub account or ChevronWP7 Labs, yes you can.
If it's SIM-locked and you need to SIM-unlock it, that should also be possible; talk to your mobile operator.
If you want interop-unlock (install and run high-privilege apps in Mango) then no, using the official upgrade will make that (currently) impossible. We're working on an interop-unlock (so-named because it makes it possible to install and run XAPs with ID_CAP_INTEROPSERVICES) for HTC phones that are already on Mango and/or have received the official update, but so far no such luck.
If you want to use the unlocked bootloader to possibly install a custom ROM in the future, be careful - the official Mango update modifies the bootloader in such a way that HSPL (required for custom ROMs) can't be used. Again, people are working on fixing this or providing a way to downgrade, but it's unclear whether this is possible at present without physically opening up the phone.

[Q] Trophy ROM for Mazaa?

Hi everyone,
I am an HTC Mazaa owner and want to know if theres a way to install HTC Trophy ROM on my Mazaa device. Since apperently Mazaa is same in everything to Trophy, so I guess no extra drivers will be needed.
I am very new to all this. So please tell me if theres a chance for installing Trophy ROM on Mazaa, if yes, how.
Thank you.

Please reply people

CPU is different
I think CPU and some chip is diffrent so It is not possible

The answer is no. The HTC Mazaa may share the same shell with the HTC Trophy, but the internals are different.

Is there any other way to install the latest ROM?
OR atleast tell me how to do interop unlock on my Mazaa.

The HTC Interop-Unlock app should work on the Mazaa, unless it has a specific block on the Connection Setup app or its firmware version is too high.

HTC interop-unlock is not working on my Mazaa that has mango. Please help.

... Did you read the info on what is required for the app to work? What's your firmware version number? Prior to Mango, were you able to use provxml apps?

I feel your pain, I have interop unlocked my Trophy twice but with this latest firmware it's impossible. We will have to wait for a custom ROM.

Verizon Trophy is now supported in V3 of DFT's HSPL unlock. I have written a HOWTO guide for Verizon Trophy.
Mazaa, I somehow doubt if DFT is working to support, but you'd need to contact them and ask. They can only work on phones they can get their hands on, and they may not be able to get a Mazaa.
It seems that Mazaa has one stock rom available (i have no way of verifying if this rom works), but it is for Mango. I do not know if this phone shipped with NoDo or if you can find a stock NoDo from for it (perhaps try private messaging Football to see if he has a connection that can get roms for this phone??).
Verizon Trophy can be downgraded to NoDo using the same rom listed in my HSPL guide (it is the only NoDo rom that isn't a store demo).

Hi,
I uploaded the stock mango rom. It works.
I personally don't know anyone with a stock nodo rom for the mazaa.
Connection setup should exit with "no database found" or something like that. Yes, very lame.
On the whole, there's no way to interop-unlock the mazaa yet.
Interestingly, if you register the phone's serial on the htc website, it registers as a SPARK_W, which is the same as the verizon trophy. I haven't tried using hspl v3 to unlock it, so update us if you get anywhere.
but if you do screw up, then just use the stock rom above. ;-)

I am ready to try HSPL V3 but I can't enter the phone's SPL mode. The Volume Down + Power On is not working for me. Can someone guide me on how I can use HSPL V3 on Maaza.

Please reply.

reply please.

[Q] Please help??

Hey, I have a HTC surround running windows 7.5 the os version is 7.10.7720.68
And I recently have tried to developer unlock my phone using chevronwp7.
But everytime I press unlock, it says I'm having problems connecting to your device, make sure it is pin unlocked and Zune is running; which it is. Can someone PLEASE guide me in the right direction? Thank you guys so much

Zune must be closed and your HTC should not be on the lock screen

Wrong thread!

I thought Zune must be OPEN. Anyways, I tried it without and it didn't work. Is my phone os too new? What else can I do? Thanks so much for your reply too

Have you installed Windows Phone SDK?
Have you installed Windows Phone Support Tool?
Have you installed Microsoft .NET Framework 4?
If yes read here ChevronWP7 Labs FAQ or contact support Chevron for solve your problem

Okay I'm still very new to windows phone 7, as I stated, I have wp7.5, os:7.10.7720.68.I have boot loader: 4.3.2250.0(128976). can someone please tell me how I would go about flashing a stock ruu? Do I have to mess with rspl/hspl yet? Please can someone help? I'm sorry for taking your time as well. Thank you much.
And also, sorry for being such a dreaded noob, but what application should I install for the bootloader mode when connect my surround in? Im on windows xp. Thanks again so much, I don't know what I would do without you guys.

Okayyyyy... a few things.
First. it looks like you're trying to use the original ChevronWP7 unlock. That tool is dead, and has been for over a year (it only worked on pre-NoDo ROMs). This is well documented. I'm not sure why people keep trying it... you'd think they'd read up a little before trying to use a hack on their phone.
Second. Why do you want to flash a stock ROM? (RUU = ROM Update Utility) In any case, the procedure is simple: turn the phone off, hold the Volume Down button, press Power to start the phone again. It'll boot to a screen with bands of color and yellow text. Next, connect it to the PC. You'll need the relevant drivers; Vista and up will install them automatically but for some reason you're still running an 11-year-old OS on your PC so you might need to install them manually (I think they are included with the Windows Mobile Device Center download from Microsoft). The phone should say USB at the bottom when it's connected; at that point just run the RUU program.
Thrid. RSPL / HSPL are replacement bootloaders for WP7. They allow installing custom ROMs. If you want to do that, you'll need to first downgrade your current bootloader; SPL 4.3 is too high for using RSPL. Since you're not on SPL 5.X yet, I think you can downgrade just by installing an older stock ROM or radio update. Otherwise, there are a number of guides for how to downgrade the SPL.

That's the reason I need to downgrade lol thanks

By chance, do you know the new way to unlock or do I have to flash a custom rom? Thanks

You are on a developer-locked HTC phone? The first option is to try getting dev-unlocked, for example by getting an AppHub account or a friend who has one. They're free for students (go through Dreamspark). The second option is to use a custom ROM. The third option is to wait until a new hack is found.
Once you're dev-unlocked, you can use the Interop-Unlock app from Heathcliff74 (the HTC one, specifically) to allow unlimited sideloading. Then, you can install WP7 Root Tools 0.9 to get nearly full access to the device.

Thanks so much. Will report back with results.

So sorry, but I did all the research I could and couldn't find an updated method of going through dreamspark. I registered and man I hate myself for this, but can anyone help me please?
EDIT: I am enjoying interop unlock on intrinsic ROM and I love it!!! Thank you all so much for your help! My next and hopefully last question is, is it okay to update my radio while I have hspl? Or do I have to ospl first thanks!

Need a couple of questions answered

Hi I recently fixed my HTC HD7 after a few months because my phone locked itself for no reason and my SPL was 5.1xx =.=, I just downgraded it using this method http://forum.xda-developers.com/showthread.php?t=1597837. I used this rom to downgrade it "RUU_Schubert_hTC_Asia_SEA_WWE_1.54.728.01_Radio_5.51.09.29_22.32.50.10_Signed_SCHUBERT_RELEASE"
After so many updates that i missed I am now lost on what to do to my phone to get the lastest tango update. Please don't reply telling me to use the seach button because i've tried and I am not really good with this flashing phone stuff.
Can someone be kind enough as to link me and tell me instructions onto getting my phone back to an updated version.
My phone specs:
-HTC HD7
-SPL 3.xx
-Not full unlocked
-Not interop unlocked
-Nodo
I think my next step is getting a custom rom from DFT http://forum.xda-developers.com/showthread.php?t=1195647 but i can't seem to find the newest tango rom and what i should do to flash it on my phone.
Please help me !!:laugh::good:

The best place to get ROMs is from the phone-specific forums (in your case, the HD7 forums) here on XDA-Devs. You'll also need to install HSPA before you flash your custom ROM; the instructions to do that are on the WP7 Dev&Hacking sub-forum. Once you've got HSPL (make sure your bootloader version is right!!!) then you can install a custom ROM. The program to do this is called ROM Update Utility, commonly "RUU", and usually when you download a ROM it will come pre-packaged with RUU. If not, you can download something that doe come with RUU and replace the packaged ROM image files with the ones from your custom ROM.
