Hello everybody,
Last week I bought a HTC HD7 via ebay. After unboxing it I connected it to my laptop and installed Zune. Zune said that an update is available, so I downloaded and installed it (now I have no recovery point).
As I am very interested in developing and want to have the possibility to modify the device as I want, I wanted to unlock it.
Because I am not already 18 years old, I can't buy a token for ChevronWP7 to unlock it. Normally, students can get free unlocking through DreamSparks, but I live in Germany and neither have an ISIC card nor a .edu-E-Mail-Adress.
So I have to downgrade my HD7 (Ver. 7.10.7740; SPL 5.10.2250.0) to unlock it with the free version of ChevronWP7 for older WP7 versions.
I tried all known methods to downgrade but it didn't work for me.
I can't flash another ROM, the utility says 'Flash Write Error' and I can't restore it, because I haven't made a backup before updating.
The DFT-Tool doesn't work with SPL 5.xx.
Now, I can't downgrade my WP7-Version and my bootloader version.
Is there any possibility for me to unlock my HD7?
Here are some extra informations about my HD7:
Model: HTC HD7 T9292
OS version: 7.10.7740.16
Firmware revision number: 2250.21.51002.207

Radio hardware version: A.102.0.D4

As I am a german student, I have to excuse me for my bad english

Hi,
is there any solution for a halfbrick (no usb connection in tricolor bootloaderscreen), beside goldcard, yet?
Someone mentioned, that you can "restore" bootloader by using the oem cabs from your phone manufacturer. I tried that (with the mango update for htc and the newest ones via cab sender). They were installed but nothing has changed.
Current phone is HTC Trophy
OS: 7.10.8107.79
Firmware: 2250.21.51201.707
HW: 0003
Radio: 5.69.09.05a_22.50.50.21U
Bootloader: 5.12.2250.1(134400)
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.

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

Hello,
I would like to upgrade my HTC Trophy to WP 7.8.
I found this ROM, but do not know, if it is compatible with my phone (details about my phone see below):
http://forum.xda-developers.com/showthread.php?t=1909006
I am currently running on an HTC Trophy with A1 Branding. It was Chevron unlocked (pre Nodo) and updated to Mango maintaining the unlock. For some reason I got relocked (I suppose a bootloader-update has caused that). I have a developer account, but at that time I wasn´t able to unlock my device (I got an error while trying to register the device). The Tango-update I am running now fixed that issue. I´m not sure, If any other unlock (interop) has survived this procedure, but I think the developer unlock has resettet all other unlocks.
Now I want to have a full unlock again. If the above ROM is not compatible with my Device I would also like a solution to fully unlock my device, so I can unregister it afterwards in the developer center while maintaining the unlock.
If the above ROM does work, I would like to backup some Data from my Device, before Flashing the new ROM (to restore it afterwards). What I want to Backup:
SMS (found this, but needs interop unlock)
XAP´s from sideloaded Apps (can I get these from the Device to reinstall them after the new ROM has been flashed?)
Savegames, PDF-Dokuments, Appsettings
Here my phones Detailes:
Model: HTC Trophy
OS Version: 7.10.8773.98
Firmware Version: 2250.21.51201.177
HW Rev.: 0003
Radio SW Version: 5.69.09.05a_22.50.50.21U
Radio HW Version: A.102.0.D4
Bootloader Version: 5.12.2250.1(134400)
Chip-SOC Version: 2.2.5.0
Any help, Ideas, solutions are much appreciated.
Thanks in advance!

You can't backup sms or apps on dev (only) unlock device !!!!
Documents are all of them allready in the skydrive ...so they will be avalaible to you ...
The app Reintaller will try to reintall all apps (from marketplace only)
You can flash a new custom rom but first you must downgrade to a pre-nodo official rom (with usb Y cable +goldcard) and then install HSPL
Search the site for more info ...and if you still question i will try to answer them ...
Thank you for your quick response, colossus_r.
Seems that I can´t do much, since I don´t have an Android phone for creating the gold card nor do I have an USB Y-cable (the smaller problem )...
Really no possibilities to backup SMS, homebrew Apps or App-Settings like Savegames with developer only unlock? - Or is there any possibility to expand the dev-only unlock?
I suspect that I have to stay at my dev-only-unlocked Tango state, If I don´t want to loose any Data or Apps?!
