[Q] Help reverting to original rom - Windows Phone 7 Q&A, Help & Troubleshooting

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] 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] 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] Easy&BestWay2Get2LASTMango+FullUnlock+Original Stock ROM [HTC Europe]

Hi guys.
Im looking for a good tutorial for 3 days now, like you know.. whats the best way to get a fully unlocked orginial htc european schubert device?
There are all these custom rom's (which is just awesome.)
But there are also some people that would like to keep the original rom.. maybe slightly modded so its unlocked and doesnt relock.
I know there are Posts like this that explain how to go to Mango + JB .. but they are like 5months old and for some it doesnt work anymore.
Isnt it possible to just have the latest stock rom with a little "customization" (e.g. unlock / prevent relock) in it ?
greets dev
Stock ROMs *cannot* fully unlock right now. It's quite simply not posible at this point. I'm working on it, but don't expect any breakthrough in the next few weeks. This will take time.
In the meantime, a stock ROM can interop-unlock just fine. To interop-unlock, and maintain interop-unlock, you need to have firmware version *.*.4XXXX.* or lower. Your firmware version goes up when you install HTC updates, so don't do that! There's one HTC update that comes with Mango, if you're upgrading from NoDo. It will break apps like TouchXplorer, but it can still be used for interop-unlock (although many interop apps won't work).
Note that I'm assuming your phone is dev-unlocked in some way. If you don't have either an AppHub account or a ChevronWP7 Labs token, you can't interop-unlock either. Making the original ChevronWP7 Unlocker work is hard now, even if you flash back to an ancient version ROM that can use it (like 7004).
Anyhow, after upgrading to Mango, install the HTC Interop Unlock XAP (it's in Heathcliff74's Interop Unlock guide thread on the dev&hacking sub-forum) and follow the instructions in the thread. That will interop-unlock the phone, enabling the installing of as many apps as you want, and allowing the use of apps with ID_CAP_INTEROPSERVICES in their manifests. It will also prevent automatic relocking of your phone.
That's as close to fully unlocked as a stock ROM can get right now. If you need to be more unlocked, there are three options: Install a custom ROM (probably requires downgrading your bootloader to SPL v3.1 or lower), wait however long it takes to figure out how to do full unlock on a stock ROM, or wait the relatively short time for Heahtcliff74 to finish and publish WP7 Root Tools v0.9, which will support HTC and will allow you to elevate any app to root (not the same as full-unlock - you still won't be able to run homebrew or ported WinMo EXEs, for example - but fairly close).

Windows Phone 7 Downgrade Help

hey everyone, i recently sent heathcliffe a message regarding downgrading my HTC. i now need your help... i sent him this message, and discovered that its not possible using cab sender....:
"ive been following your posts for a while now, wathching out for a new post in the interop unlock section,
i have a htc mozart on o2 in the UK, and it has all of the recent updates including the newest 8107.
i was wondering, using your cab sending thread, and the dudes cab sender. bearing in mind i have a chevron unlocked phone and i want to interop using your .xap in your official thread for interop
in my mind this makes sense, however im hesitant as to whether these will work together, and whether, because im on o2 and the last package is just for Europe, im wondering if it will work.
thanks
and p.s im new to all this, just come over to windows phone from symbian and its all completely different, so excuse my noobness
cheers buddy"
with the reply of:
"What you want will not work for multiple reasons.
1. With cab-sender method you can only upgrade, not downgrade.
2. The OS cabs must have the same end version (you selected OS version 7.0.7008 and language pack 7.0.7403)
The only way to downgrade is by fladhing a complete old rom, but you will loose your apps and data. If you go that way, you may also choose to use rspl/hspl (hacked bootloader) and flash a custom rom that is already unlocked.
Good luck!
Heathcliff74"
so.
my question is,
where do i get a complete old rom.
and will this dwngrade my drivers so i can full unlock using deepshining rom etc...
thanks for all your wonderful answers -_-

Just got replacement HD7 from tmobile in the mail. Best way to unlock?

I had a HD7 and the charging port went so for 5 bucks I got a new one. I unlocked my old Hd7, but I have to idea how I did it, since it was so long ago.
What is the easiest way to get a full unlocked device these days?
Links would be appreciated, thanks!
Full-unlock requires a custom ROM. You'll almost certainly need to downgrade the bootloader (see the GoldCard threads on the dev& hacking sub-forum), then install HSPL and flash a custom ROM.
If you just want root-unlock (ability to run apps with max privileges on a stock ROM), that's also possible. You'll have to flash an older stock ROM, one with bootloader / firmware version 4.x or lower. You'll also need dev-unlock, so if you don't have an AppHub account (or a friend with one) this approach won't be practical. Anyhow, once you're dev-unlocked on firmware *.*.4XXXX.* or lower, install Heathcliff74's HTC Interop Unlock XAP and follow the instructions, then install WP7 Root Tools v0.9 and follow its instructions. After that, you'll be able to run almost all the homebrew apps and have read/write access to your whole device.
