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
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(131983)
As I am a german student, I have to excuse me for my bad english

Hello all,
since some weeks I have a HTC HD7, I bought it through Ebay, not knowing that it is O2_DE-branded.
OS Version: 7.10.7740
Firmware Version: 2250.21.51002.207
ROM Version: 5.10.207.02
Bootloader Version: 5.10.2250.0(131983)
I know that there is a possibility to downgrade the bootloader 5.xx thanks to ansar, but it's not available for O2_DE.
Can't I just flash Ansars Downgrade-ROM on my HD7? Because I don't know any great differences between HTC Europe and O2_DE-ROMs.
But everytime I try to flash the ROM on the HD7, it says 'Flash Write Error'. Is there any way to avoid this error?
I would really like to install custom ROMs!
Well, there's always the option of using a goldcard or similar to downgrade. It requires a little bit of hardware (modified USB cable and a USB SD cardreader) but it's not very expensive and the procedure is pretty easy. That lets you downgrade the SPL so you can install HSPL and then flash whatever you want.

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)

Please help me
Hi,
after I sent my Trophy to a HTC repairment center, they gave it back to me with the newest OS. Therefore my interop unlock is come. Now I would like to have it interop unlocked, again.
My system information:
OS-Version: 7.10.8107.79
Firmwarerevision: 2250.21.51201.162
Hardwarerevision: 0003
Radio: 5.69.09.05a_22.50.50.21U
Bootloader: 5.12.2250.1(134400)
Chip-SOC-Version: 2.2.5.0
As I know, its not possible to unlock it anymore, therefore I tought of installing a custom rom. For this I would need to install HSPL first, dont I? And for HSPL I need to downgrade my OS because of the version. I read somethign about the goldcard method, but did not understand evertyhing. Which OS version do I need to chose for the "device-specific .nbh image"?
It would be really kind if you could answer my questions - looking forward to help
Thanks...
Are you a Spark or Spark_W user (Verizon CDMA model). Anyway about it, check in the Trophy area on this site. THere is a lot of info for both models.
As my case, I have a Verizon Trophy. I was on the same level as you.
I needed to HSPL, down grade the OS version, then I could flash a rom. Your on the right path.
Goldcard method is if your partly bricked, it does not sound like your at that point.
When chosing your rom, just make sure you use the correct rom for your phone, a SPARK (GSM) rom should not be used on a SPark_W (CDMA) and back.
Good luck...
Hi,
I have a normal Spark (Vodafone). If I want to downgrade the OS I need to use the goldcard method or? And which image do I have to choose? Because there are a lot of them available. Does it make a difference, which branding I have?
Thanks for the answer
/EDIT: http://www.filefactory.com/f/0dacfac3a33cc378/ I have this list, but no clue, which version I need to choose...
From a 5XXXX bootloader, I believe you'll need to use GoldCard or SLSPL to downgrade to a HSPL-compatible version. GoldCard is the method that I know will work.
And which version should I use? Because I am kinda confused becuase of the mass of available versions...
Would this version work on my vodafone branded phone? "RUU_Spark_S_Vodafone_DE_5.12.162.01_5.69.09_RELEASE.exe"
Or which version would you recommend?
Thanks
Would this work?
Please tell me whether this will work...Or which version I should use instead of this.
