Hi!
First i want to say that i know that there must be other threads about this problem but my lack of knowledge in these matters has made it very difficult to actually know what to look for.
I have a htc Sensation, which is branded (for an operator called the three).
My goal is in the current situation to try to get the original version of the HTC Sense. The version you get on a non-branded version of HTC Sensation.
Later I am thinking about getting CM7, but that is not relevant here
When i started to look into how to proceed I found that I know very little about these things.
And so I turn to you for help.
My first question is: Can you use HTC's official method to unlock the bootloader on a branded phone? I have software number 1.45.771.4 (which is 2.3.4) but on HTC's website it says that you should have 1.45.401.2.
If not, what is the next best way to unlock the bootloader?
My second question is: Can you somehow get the original version of the HTC Sense? I do not mean a custom version of the original, but the actual original? Is there any relevant difference?
My third and final question is: How do I install the original version of the HTC Sense on my phone?
Hope I have explained well enough and that someone has the desire to help me with my small troubles

i uses this thread to debrand my vodafone device (it is rooted via revoltionary tools) http://forum.xda-developers.com/showthread.php?t=1193033
Sent from my Sensation using XDA App
Maybe i should clarify that i think it is kind of scary to use unofficial methods and i would like to find a way that are as "Safe" as possible.
I know that "Safe" may have little to do with the method being official or not but i would first like to explore the official ways before turning to the unofficial ones simply because i think that they are scary.
The ONLY way to debrand is:
1. S-OFF
2. Write the Super CID to your phone
3. Flash an unbranded ROM to your phone
This is easily done with the Revolutionary method, and is 100% reversible should you need to return the phone
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.
I am wanting to interop unlock my hd7 running latest mango. i tried the htc unlock xap and the connection setup app (which tells to use interop unlock as country) but to no avail. has anyone been able to get interop unlocked on htc hd7 ?

Do you have it developer unlocked first?
HTC Have 2 OEM Update after Mango
if you updated your Phone with Second OEM Update, you can not Interop Unlock your phone
yes i have a dev account from app hub.
how do i find out if im running second oem? do you have the build number handy? the os version i have is 7.10.7720.68
It's not the OS build number, people. HTC controls the firmware number, not the OS number (that's Microsoft code). 7720.68 just means the RTM release of Mango. I swear, I write this so often...
If the third digit grouping of your firmware starts with 4 - that is, if your firmware version matches *.*.4XXXX.* - or lower, you can use the HTC Interop Unlock XAP. It *might* even be possible with *.*.50XXX.*, but I don't think so, and it certainly isn't possible with *.*.51XXX.* or newer.
well that helps a lot, ya my firmware shows 51004. so are there any workarounds as of yet?
The only work-around I know of is to downgrade. You can roll back a Zune restore point from before the firmware update(s) was installed, interop-unlock, and then reinstall the updates if you want (I've elected to semi-permanently keep my phone a few versions outdated on firmware). You could also flash a stock ROM that includes an older firmware. Be aware, however, that either option will lose some data - everything newer than the backup if you restore, everything on the phone if you flash a stock ROM.

Hey thanks for the information, I was wondering if there were any guides you can point me to on how to flash from a stock ROM. I have an HTC HD7.
Thanks again for your help. i know sometimes its tiring explaining the same thing over and over, but it is much appreciated.
Go to the HD7 ("Schubert") portion of the XDA-Devs wiki (http://forum.xda-developers.com/wiki). I'm pretty sure you can find the download links for stock ROMs there. You could also try the HD7-specific forum section. You'll download a tool called a RUU (ROM Update Utility) that will have some image files (extensions like .NBH and .NB) along with it. You put the phone in bootloader mode (four bars of different color - you have to boot the phone while holding the Volume Down button). It should have yellow text, and at the bottom should say "Serial". Connect the phone to USB. Your PC will need to install a driver (normally this will happen automatically, if not, use Device Manager to tell the computer to search Windows Update for the driver). Once the driver is installed, the "Serial" will be replaced by "USB". You can now run the RUU program.
I *strongly* recommend creating a backup first! The RUU will wipe all data on the phone, and if the flash fails for whatever reason, you'll be unable to boot the phone again.
Ok Thanks, That was helpful. i read a few guides and I think Im ready to try. i just wanted to ask a quick question before diving in. Hope you dont mind. Some threads make refrences to certain Bootloaders being unable to go through the downgrade process (by flashing a Stock Rom). Is this correct? My bootloader version is:
5.10.2250.0(132968)
If it doesnt matter than are there any other things that would prevent me from doing this process?
And one more question and I promise to leave you alone lol. I plan on backing up my phone before beginning, but if the flash fails for whatever reason and the phone is unable to boot again as you warned, will I still be able to connect it to Zune and restore my backup? Thanks again. Hopefullyone day I can give more to the community once I get used to it.
Booting the phone while holding the Camera button will put it in backup/restore mode. If you connect the phone to the PC while it is in this mode, and the Zune software is running, it should automaticlaly try to restore.
Your bootloader (SPL) version is too high to install HSPL (needed for custom ROMs), and it's high enough that it won't automatically downgrade just by installing a stock ROM. However, you should be able to install the other parts of a stock ROM (in particular, the firmware) just fine.
If needed, there are a couple ways to downgrade the SPL; search the dev&hacking sub-forum for info. I would generally recommend GoldCard, but that will require a little bit of equipment. Apparently, "SLSPL" flashing will allow you to downgrade the SPL safely as well, though I haven't tried it. These are mostly for preparing to install a custom ROM, though - stock ROMs should be installable on any SPL version.
it not work with my trophy verizon

Well?? Did it work? Would really like to know before I attempt the same
Thanks
did it work ????
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 -_-
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.
