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and then reinstall the updates if you want (I've elected to semi-permanently keep my phone a few versions outdated on firmware).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

Hi these our are HTC HD7 SPecs
OS: 7.10.8107
Firmware:2250.21.51101.707
Used to be dev unlocked + interop lock by ansar's guide now
My phone locked itself out of the blue and the only advice i was given was to :
1)Get DFT rom on it
2)Find and flash a stock official rom dating back to nodo (WHich i can't find)
Im not very good with tech and hacks so can someone who is kind enough to instruct me on how to flash a DFT rom on my phone please
I don't know what SPL or if my phone has spl etc.
I don't even understand the requirements :
IMPORTANT NOTES
1. Before doing any operations be sure you have battery level more than 50%!
Sometimes in SPL mode WP7F devices DO NOT charge. You may got a cold brick if it power down during SPL or RADIO update!
2. Stock RUU ROMs have two NBH inside, SPL_Signed and RUU_Signed.
So it's not possible directly flash stock ROM, you need extract files and remove SPL_Signed.nbh at least.
3. Rememeber if you have HSPL and you flashing stock RUU_Signed.nbh you lost HSPL!
4. Supported OS: Windows XP, Windows Vista, Windows 7.
The link to DFT rom: http://forum.xda-developers.com/showthread.php?t=1195647
answer in the tutorial i wrote, which is stickied in HD7 General.
direct link can be found in my signature.
I have a developer unlocked TMO HTC HD7 on the lates 8107 update. I have been searching a lot but can't find a way to add more accent colors to my device. I would really like to add the Nokia Blue on my device. I know that Samsung Windows Phone users have a dedicated thread for that. Its just that I can't find a similar method for the HTC devices.
Edit: After a few more tries,. I found Advanced Config Tool 1.5 ( I have also attached the xap below)
However I noticed in the manifest file that it needs Interop Unlock Services. So i removed that line.
I can run the application but cant change the accent color. It says unable to apply. Any help ??
Well, if you want an app that requires interop-unlock to work, you'll need to be interop-unlocked. Removing ID_CAP_INTEROPSERVICES so you can install an app is kind of like buying a car without an engine so its affordable: great, now you've got a car that can't drive (or an app that can't do anything high-privilege).
At this point, you've got two options. Either get your phone interop-unlocked (it's entirely possible for the TMO-US HD7; mine is) or install a custom ROM. The first option will probably require downgrading the firmware. The second option will probably require downgrading the bootloader. Both of these are possible, both have certain difficulties, and there are advantages and disadvantages to both approaches. Personally, I stuck with the stock ROM, interop-unlocked and running WP7 Root Tools.

Can you please tell me how to Interop Unlock it...I have a developer unlock phone so can sideload max 3 apps
First, you'll need to downgrade the firmware to *.*.4XXX.* or lower. If you've got a backup old enough, you could try just restoring that backup. If not, you could try either flashing just a radio/firmware update (without resetting the phone, and no, I have no idea if this will work) or flashing a full stock ROM with the older firmware (which will wipe your phone). You can find links to HTC released ROMs in the XDA-Developers Wiki; look under the HD7 (Schubert) section.
After you've downgraded the firmware, you need to install the HTC Interop Unlock v2.XAP from Heathcliff74 (check the Interop Unlock thread on the dev&hacking sub-forum) and follow his instructions (it'll use Connection Setup to interop-unlock your phone).

my spl/bootloader version is 5.12.2250....how can I flash a full ROM with an old firmware ??
It may be possible to flash an older stock ROM (check the Wiki for links to official ROMs) without downgrading your bootloader, although I've not tried. HTC phones use a tool called RUU (ROM Update Utility.exe) to flash. Most ROM downloads will come with a pre-configured RUU (it's a tiny file compared to the ROM image).
Alternatively, you can downgrade your bootloader. The two best-known ways to do this are using a GoldCard (hook a USB SD cardreader with a special file on the card to your phone) or use SLSPL (a way to unlock the SPL version so you can overwrite it with a lower SPL from any old stock ROM). The instructions for both approaches are available on the Dev&Hacking sub-forum.

thanks....let me take a look
Hi,
I'm attempting to Interop Unlock my HTC HD7.
I've just run a restore in Zune, but it appears that the earliest restore gives me:
OS version: 7.10.7720.68
Firmware revision number: 2250.21.51002.728
Hardware revision number: 0002
Radio software version: 5.71.09.02a_22.51.50.21U
Radio hardware version: A.102.0.D4
Bootloader version: 5.10.2250.0(132968)
Chip SOC version: 2.2.5.0
I understand that if I have a Firmware revision number of 5xxxx, I cannot run the Interop Unlock as seen in this thread.
From what I see, it is possible for me to download a Stock ROM, in my case, this, and run that to downgrade my Firmware revision number.
I would just like to clarify before I start this process. Is the above information correct, and to run the Stock ROM, do I simply enter Bootloader Mode, start the .exe as downloaded from the thread, and let it run (seems too simple to me)?
Also, should I manage to get Interop Unlock working on a Firmware revision number of 4xxxx, would the Interop Unlock stick once I update the phone (is normal Zune update even possible after that)?
Thanks.
Be very careful. Since you have bootloader 5.xx
Pretty sure downgrading like that will brick your device. You have to use a y-cable. Last I heard, ive had my hd7 unlocked for a while not sure of newer ways.
Look for the downgrading spl thread in hd7 development. I think that's where it is.
After downgrade spl. I would just install hard-spl and flash a custom rom. Easier.
Sent from my HD7 T9292 using XDA Windows Phone 7 App
Thanks for the reply. Didn't know about the Bootloader thing, fortunately I didn't go ahead with it yet.
I was under the impression that if the ROM is the official ROM for my region (SEA, Singapore, 728), I wouldn't require any modifications to the SPL.
I don't want to mess with the SPL or the bootloader though, I've bricked enough devices (not WP7) to have a phobia of such things. Guess I'll have to wait for a breakthrough in unlocking, unless someone has any other methods.
If you want to be absolutely safe, GoldCard (which what @reeg420 meant when mentioning Y-cable) is the most reliable method.
However, I *think* you can actually downgrade to an older stock ROM just fine even with SPL 5.x. It just won't downgrade the SPL itself the way it normally would. You can't use RSPL on SPL 4.x or higher, which is why being able to downgrade the SPL is sometimes important (people who want to use custom ROMs need RSPL).
I suggest you do a bit more searching before deciding. I have not tried messing with SPL 5.x at all; I briefly had 4.x on my phone and promptly downgraded it to 3.1 again.
Thanks. I decided to go ahead with it, but got an error: "ERROR 226 (Flash Write - FLASH write error happened. Please check your PDA Phone)", which rebooted my phone. Phone appears to be okay though, not bricked.
Looks like I'll probably need to use a GoldCard?
Edit: So it appears that the earliest ROM that allows me to HSPL is this, which has the Bootloader 1.54.2250.0(112696). Could someone check my following steps and verify that I'm correct?
1. Get Y-Cable, USB Gender Changer, MicroSD+Card Reader
2. Get GoldCard Tool
3. Get GoldCard IMG, from this thread? "My custom goldcard.img"
4. Format MicroSD to FAT32
5. Place RUU_signed.nbh extracted from the aforementioned ROM with Bootloader 1.54.2250.0(112696), renamed to SCHUIMG.nbh
6. Run GoldCard Tool, ignore CID box, use GoldCard IMG, Patch MMC
7. Connect GoldCard, Y-Cable, phone, etc, etc, etc, patch phone
8. Get DFT's WP7FG3 from this thread
9. Install HSPL (or should I get RSPL? What is the difference?)
10. Find ROM of my choice (what do you recommend?)
11. Run selected ROM's ROMUpdateUtility.exe, flash device to new Custom ROM
Q1: What happens if the GoldCard process fails?
Q2: Is there any cons as to having an outdated Bootloader?
Q3: Am I able to upgrade my device with Official ROMs in the future after performing this, or must I simply use Custom ROMs from here?
Q4: Will having a Custom ROM affect my connectivity with my network?

Answer for Q1: it will definitely brick your device
Answer for Q2: no cons that may disturb you
Answer for Q3: yes, you're able to upgrade your device with official roms
Answer for Q4: no, as i use custom rom on my device, no connectivity problems
Wow, the GoldCard step looks incredibly daunting then. Guess I'll give this a shot. Will have to wait for the stuff to arrive from Amazon though, which will probably be a while given my location.
Thanks everyone for your input
with new windows phone recovery-tool 2.0.3+: http://go.microsoft.com/fwlink/?LinkID=525569
it downloads the RUU nbh and the UEFI nbh to the following path:
C:\ProgramData\HTC\Packages\Products\0P6B1400-T-MOB010
named like:
RUU_signed_2061.30.15001.531.nbh
UEFI_signed_2061.30.15001.531.nbh
i grabbed the download links with fiddler for people without the device:
Code:
https://softwarerepo.blob.core.windows.net/softwarerepo/80c33a50-3c4b-448b-9981-e5cd74d32236/UEFI_signed.nbh
https://softwarerepo.blob.core.windows.net/softwarerepo/80c33a50-3c4b-448b-9981-e5cd74d32236/RUU_signed.nbh
mainos partition is decrypted on-device during flashing (device model specific encryption).
the same also works for other variants of the htc one w8 like verizon and at&t.
would be cool if someone could post those rom url's too.
there is no tool to decrypt the mainos partition sadly but i hope someone skilled creates it.
Will it be possible to flash the T-mobile RUU on a Verizon phone? I need to get rid of the lock on the 4G channels on the verizon version.
in theory, modelid check on device will make it fail.

Any way to change model id with regestry hack? Maybe the same hack that allowed non-Lumia devices to install wp 10 technical preview?
that is not the same. it would have no effect in this case.
modelID is checked by bootloader before flashing. it aborts at 1% with error.
what you want is a signaturecheck/mid/cid unlocked bootloader. and you're not alone.
even if you reverse-engineer the bootloader and patch it, you need a way to get it on the device.
both things are incredibly difficult with wp8 nowadays because of the security measurements.
the previous work i did on wm/wp7 custom roms is not possible for wp8 until that happens.
The recovery tool does not work with the Verizon version of this phone (at least when i tested it the day the build came out). I had to use the leaked rom to flash back to Windows 8.1 on my Verizon Windows M8
I do have the Verizon .nbh's lying somewhere, will look for it when I get home
