MicroP(LED) 0x07
TOUCH S1(v1.7,#1624)
SD SANDISK 7580MB Class0

(and no serial shown, is that normal???)
and in windows information i get
OS version:7.0.7004.0
Firmware revision number: 2250.09.12302.401
Hardware revision number: 0002
Radio software version: 5.51.09.06a_22.30.50.09U

so, this is what I am gona do
1.- launch rspl and install HSPL using "DFT_XSPL_WP7FG2" file from

2.- install the custom rom, like this one from ansar
[NewTech 8107 22L TU]HD7_Europe_5.12.401.04_Radio_5.71.09.02a_22.51.50. 21U by ansar
using the tutorial section "instructions to install a Shipped or Custom ROM" from
[TUT] How-to: downgrade SPL, flash XSPL, flash Custom ROMs & Radios
and that's all right?
also I have a few questions
a) I'm form Spain in europe, will the custom rom above mencionated be ok?
b) Do I need to install any custom radio?
that's it, hopefully everything will go fine, very nervous here
many thanks and a great forum a community

New To HD7 and Windows - Need Help Flashing and Unlocking

Hi i just bought a HTC HD7 16Gb on eBay which is on o2 and thought il use the windows 7 mobile devices since the interface and overall phone is brilliant.
I want to unlock it (not sim unlock) and instal a custom ROM.
I cant remember what version the had when i opened it but im pretty sure it only said "Windows 7". I have now updated the phone and this is what i currently have.
Model HTC HD7 T9292
Software: Windows Phone 7.5
Total Storage :14.63
Available Storage: 13.75 GB
OS Version: 7.10.7720.68
Firmware Revision Number: 2250.21.40501.206
Hardware Revision Number: 0002
Radio Software Version: 5.69.09.29a_22.50.50.21U
Radio Hardware Version: A.102.0.D4
Bootloader Version: 4.5.2250.0(129291)
Chip SOC Version: 2.2.50
Now Sorry i know this question has been asked countless times but after reading for 3 hours i just want 2 make sure i do everything right so i don't want to end up with a brick. If i said any errors could you correct me please.
From what i understand The radio version isn't important but it is the Bootloader version that matters right? Bootloaders with 5.xxx need to be downgraded via a special way otherwise 4.xxx or lower bootloaders are ok however bootloader lower than 3xxx are better to have?.
Do i need to downgrade my OS version before i can even begin flashing?
Once you instal a custom ROM not all custom ROMS support being up datable via Zune without bright right?
So in simple terms can someone advise me the steps to first unlock my phone so i can instal my XAP files, then secondly how would i go about installing a custom ROM.
Thanks You and Sorry for the trouble.

hi Awofadeju
need more info .... phone mid number.... found on bootloader screen
first thing to do is check to see if your phone can be installed with Cotulla HSPL
if not supported dont waste any more of your time
1, yes you have to downgrade your OS to downgrade your hspl
2, ONLY after you have downgraded your Hspl... then install Cotulla HSPL
3, some custom roms are updatable via zune but not recommended
4, sh4d0w86 has the best install instructions HERE
5, read sh4d0w86 instructions and follow his steps....link....http://forum.xda-developers.com/showthread.php?t=1295068
cheers and have a gr8 day
thanks button is next to qoute button

I also just recently got an HTC HD7 (TMOUS) with the following info
OS Version: 7.10.8107.79
Firmware revision number: 2250.21.51202.531
Hardware revision number: 0002
Radio software version: 5.71.09.02a_22.51.50.21U
Radio hardware version: A.12.0.D4
Bootloader version: 5.12.2250.0(135916)
Chip SOC version: 2.2.5.0
Bootloader screen says
Security Unlocked
PD29*** SS-BC (4k)
SPL-5.12.2250.0(135916) NMG
MicroP(LED) 0x07
TOUCH S1(v2.B, #1625)
I'm fairly new to custom roms and flashing and would like to ask if I can flash any custom roms with the Security unlocked bootloader or do I still need to downgrade my SPL as to avoid bricking the phone.
Thanks in advance.

[Q] How to downgrade SPL 5.11.2250.0

I use the manual, how to downgrade HD7: http://forum.xda-developers.com/showthread.php?t=1196183 , but when process start i get error.
My question is how i can downgrade my HD7 without Y cable? It is possible or not? And how?
About my phone:

You have an O2 UK operator device.
The above method, Ansar's SLSPL rom is developed for Europe devices and won't work for you.
The only other methods to downgrade SPL 5.xxx are the goldcard and Zune restore point methods.
Goldcard method - requires a Y cable (either home made or purchase from online) 1gb - 2gb SD card, card reader and you need to download a stock//shipped Pre-NoDo/NoDo rom, the goldcard tool and goldcard image.This method you extract the ruu_signed.nbh file and renameit to SCHUIMG.nbh from the Pre-NoDo/NoDo rom and put it on the SD card, run the goldcard tool, select the goldcard image and patch MMC to turn the SDcard into a goldcard. Then use the Y cable to flash the SCHUIMG.nbh file to the device while it's in "USB host mode" Once the SPL is downgrade to at or below 3.xxx you can install XSPL (RSPL/HSPL and then flash a custom rom of your choice.
You can follow the goldcard tutorial here -
http://forum.xda-developers.com/showthread.php?t=1597837
You can use this rom to downgrade with the goldcard method and the Zune restore point method -
https://rapidshare.com/#!download|3..._Radio_5.63.09.13_3a_22.36.50.15U.7z|9309|0|0
Zune restore point method by Zubair - Restore the device to a Pre-Mango state through Zune. Meaning you updated the device to Mango using Zune and still have the PC that you used to do it on. This method you restore the device through Zune, when you restore the device it doesn't change the SPL... You have to re-update the device through Zune back to Mango and then the SPL is downgraded to 4.xxx the key point here is that during the re-update process the device will reboot twice, once to change the SPL to 4.xxx and once to actually install Mango and at this point you have to stop the update process before it install the next update which is the HTC firmware update, if that's applied then the SPL is upgraded to 5.xxx again. Once the the device is restored to 4.xxx then you can flash the Pre-NoDo/NoDo rom while the device is in bootloader mode to downgrade the SPL to at or below 3.xxx to install XSPL (RSPL/HSPL) and then flash a custom rom of your choice.
