[Q] Downgrade HTC HD7 from 7740

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

[Q] Downgrade 5.xx Bootloader

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.

[Q] How to get DFT ROM on a locked HTC HD7 5.1xx firmware?

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.

[Q] How to upgrade from Tango (Developer unlocked) to 7.8 with Backup of SMS and Apps

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?!
