[Q] Help needed to get Mango. Reward inside :-)

So, I'm the (un)lucky owner of a Vodafone branded HTC Trophy. I installed the latest HTC update which landed me on SPL version 1.22.2250.
I figured I want to install this version of Mango since I'll be able to to the rest of the updates trough Zune.
I don't know if I'll be needing to unbrand this device or not, I only know that if I run the proper RUU tool against my RGB screen (boot loader?!) it comes out with error 266 and leaves my phone hanging. I then need to reboot my device by pulling out the battery.
I was fairly advanced with Android's ROM way, and by means are not a stupid person. I googled quite a lot and read through most topics in this sub forum but it doesn't make sense yet.
What I'll be needing: A foolproof way to get to the latest Mango version. I don't care whats in between and are willing to take moderate risk such as flashing HSPL. There are so many ways and terms here I simply don't have the time to figure it all out. Time is money and since I'll hopefully be sparing out a few hours with this way I offer the lucky winner of writing me a fool proof step of plans $10 on paypal.
Also, bare with me. English isn't my native language.

You can contact me in dutch and i might be able to help you out.
Though i have samsung device.
What version are you running? Did you try to upgrade to Mango beta? are you dev-unlocked?
If you are on NoDo and unlocked, make sure you install provxml deployer and run it before upgrading to mango.
Try installing the zune beta and all the files, than do the upgrade, now run the htc connection setup (this will execute some files which will fully unlock your device). After you did this, make sure to run provxmldeployer again, this will place the same files back, you will need these after the second update to mango b2.

This is what I did to get the same ROM.
I had the 1.22.2250 SPL as well, but then I thought to myself that I don't need useless vodafone apps on my phone, I just need OEM apps because they are more useful than a shortcut to vodafone 360.
So, here's what I did:
1. Go here and download the appropriate ROM for your Trophy. You must get 7004/7008 version. You should download the appropriate ROM that matches the characteristic value of your phone. The ROMs in this thread are all branded, but flashing this ROM will downgrade your OS version and SPL version to 1.09 or 1.10 so you can HSPL later.
After the ROM has been downloaded, extract the zip file somewhere easy to find (eg. desktop).
[Step 2 will erase everything on your phone]
2. Connect the phone by holding down volume down key and connect it via USB. Wait until appropriate drivers are installed. Flash the ROM you downloaded from step 1. This should take less than 10 minutes. After flashing, Trophy will restart and boot to normal. Turn it off. Your phone is still branded in this step.
3. After flashing, download DFT's RSPL/HSPL here and be sure to get the second version. Extract the files somewhere easy to find (eg. desktop). This tool will let you install customized ROMs/unbranded ROMs on your device. Therefore if you replace your SPL with HSPL, you will be able to install the unbranded Mango ROM.
4. Hold down volume down key on the Trophy, and connect it via USB. Trophy will go straight to bootloader state, and run the DFT_RSPL_WP7FG2_LAUNCH exe file . Select the nearest version of SPL shown on your Trophy, and click install. If Trophy reboots, flash was successful, if not, try again until you get RSPL.
5. After RSPL, do step 4 again, but this time, run DFT_HSPL_WP7FG2_LAUNCH and install HSPL, not OSPL. After HSPL, Trophy will reboot. If Trophy successfully boots to Windows Phone, then you have done it right.
7. Go here and download your ROM for Trophy which is RUU_Spark_S_HTC_Europe_4.06.401.00_5.69.09_RELEASE.exe. This is the unbranded ROM which will remove carrier (vodafone) apps.
8. Turn off Trophy and connect it by holding down volume down key and connect via USB so it goes straight to bootloader state, unzip the ROM downloaded from step 7 using winrar or winzip.
9. Open the extracted folder and delete SPL_signed.nbh as this will overwrite your current SPL and will brick your Trophy.
10. Run the rom update utility and happy flashing! Trophy should restart after flashing.
So there you have it. After setting up your Live account, you must go to the marketplace and download HTC Connection Setup and run it. This will configure your carrier settings (3G/HSDPA, MMS) to your phone since this Mango ROM is unbranded and does not carry and customization by your carrier (vodafone).

Cool. Now trying the method from downloaderintruder
Edit: Seems to be working. Flashing final Mango ROM now, will report back when running.
Edit2: Done!

Fantastic - thank you.
I've been trying to do this for a week but to no success

Hi, I still get a ERROR 266 when flashing with the RUU_Spark_Vodafone_ELL_1.10.168.04_Radio_5.52.09.16_22.33a.50.10U_by_ansar ROM? Also get the same if I try to flash the RUU_Spark_S_HTC_Europe_4.06.401.00_5.69.09_RELEASE ROM... I've been struggeling with this the past 5 days and would really appreciate any assistance.

Resolved this by changing from a USB 3 port to a USB 2 port? Weird but it worked...

Do i need Y usb cable to do this? Because i`ve tried this with standard usb cable from htc and my Trophy stucked in "USB host mode" screen.
I don`t have that Y cable, and i was looking for solution to debrand phone without Y, and i`ve found this thread, wheres no word about Y cable but now i don`t know
--------------------------------------------------
Ive found solution:
Instead of pressing volume button and connecting it to usb, i`ve holded volume rocker down, and hit the on/off button, when tricolor screen appeared i`ve released volume button and THEN connected my phone to my PC via USB

If you want to go back, you will need to get the 7004/7008 version of the ROM with 401 CV. Check out ansars ROM in the Trophy forum and download that. Go to the bootloader state, and flash it straight to your phone, this will downgrade from 7720 to 7004/7008 (unbranded).
To go back to branded, first you must HSPL your device after downgrading, then download the original ROM for your trophy and flash it. You don't have to delete spl_signed file, you only had to delete this in the mango rom because it will brick the device since the spl version from mango had a huge leap from spl1 to spl4.
Be aware though, some Trophy users who flashed ansars ROMs didn't get past 7008 to get the PreNodo/Nodo update, so you can't use your backup at this time. I'm still looking for a solution on this, but since I don't really like branded phones I'm all good with my Trophy.

Updates will still go through via Zune.
For the problem regarding how to go back to your backup, here's a theory, IF there will be mango ROMs for our trophies like there's Nodo, we can install that ROM and restore our backup via Zune. That is, IF there will be Mango roms for our trophies with matching CV's.

Now I have the error code c101b001 in the marketplace.
Do you know why?
thaks

after update to 7740 some apps don't work...

hello, yesterday i've updated my phone to 7740 and today i've noticed that i can't use some apps like navigon, touchexperience and so on. before update all these apps worked but not now. could you tell me what can i do?

thanks for sharing, I'll wait with my update I think. If you find the solution please let us know!

If you used the official update route your phone must have been relocked during the update to 7740 hence you have no ability to side load apps. Roll back to the previous 7720 version through Zune and stick with that if the phone was Interop unlocked, if it works.
If your bootloader has changed to version 5******* theres not a lot you can do yet to unlock your device, apart from the Goldcard method.

I thought that the newest zune doesn't backup the complete device any more... is this true? is it possible to go back to 7220 without hard resetting your device?

very strange...
in the morning tried to downgrade to 7720, but unsuccessful. after few hours tried again, but it seems that my phone is half-bricked...
anyway, connect the phone to pc, zune started and i see "restore"!... right, i can restore to 7720 and now my apps works!
tried now to update to 7740 offline, but the same situation: can't use apps!... tried to interop-unlock in 7720 with htcinteropunlock.xap, but can't find in connection setup "interop unlock".
please help me, because i really need to update to 7740 because of outlook forward message update and also because i need to use these apps (navigon is one of them).
it is possible to have a 7740 phone with interop-unlock?
thx.

You might be lucky and stay unlocked by updating from the restored version of 7720 to 7740 by trying one of these methods:
While running your unlocked 7720 install the attached Advanced Configuration 1.5 .xap swipe the screen and go to 'Tweaks' and make sure the box 'Prevent phone from relocking' is ticked. Now run the 7740 update and see if that keeps it unlocked.
If the above doesn't work go back to the 7720 backup and install U2M7720 V1.2 and follow the instructions below before running the 7740 update.
Select U2B2, complete provxml and tap on done
Finally just tap on Chevron Unlock (will exit U2M7720)
DO NOT RUN Connection Setup now
Update to 7740
NOW run Connection Setup
Let me know if either of these methods work for you, and could you please let me know which bootloader version you have on the 7720 and 7740 ROM versions, I know you have already updated and it could be the same for both now.
The bootloader version is found by powering off then powering back on while holding the volume down button in. To get out of bootloader mode hold the power button down for a few seconds until the phone turns off then power it back on.

first method not work.
try now the second. which version of connection setup must be installed?
just tried: it seems that even this method failed. connection setup don't start and the other apps don't work.
i will try again to restore and install connection setup from marketplace.

spl - 5.10.2250.6 (132274) mng
update: still locked...

It'll be the 5.10.2250.6 bootloader that's keeping the phone locked, there is no easy work around for it that I'm aware of, unless you flash back to a manufacturers ROM using the Gold card method then install a custom 7740 ROM using RSPL/HSPL.

it's very strange because on saturday morning my phone wasn't half-bricked, but when tried to flash an other rom it appears that is bricked...
and why when restore to 7720 everything working?!?!

That'll be the bootloader version causing those issues.

I had a similar issue a few months ago and I was able to flash back to my phone's original firmware which downgraded the bootloader back to v1.07.
I'm guessing most of the half brick situations are caused by incorrect firmware being loaded when flashing back to an older version.
You may need to identify your CID and operator for your phone.
Instructons and links below:
----I haven't tested this with the verizon version of the handsets as I don't own one of those handsets. You may want to check the forum for any bricking related issues with those handsets & Flashing firmware will reset your phone's settings including contact links, message threads and saved game progress etc...----
Identify your phone's original firmware type (CID and Operator)
Flash with the corresponding firmware
Reinstall HSPL/RSPL from DFT Team
Now you may flash the required firmware such as DFT, custom builds etc...

[Q] Change Accent Color on my TMO HTC HD7

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.

[Q] Please help??

Hey, I have a HTC surround running windows 7.5 the os version is 7.10.7720.68
And I recently have tried to developer unlock my phone using chevronwp7.
But everytime I press unlock, it says I'm having problems connecting to your device, make sure it is pin unlocked and Zune is running; which it is. Can someone PLEASE guide me in the right direction? Thank you guys so much

Zune must be closed and your HTC should not be on the lock screen

Wrong thread!

I thought Zune must be OPEN. Anyways, I tried it without and it didn't work. Is my phone os too new? What else can I do? Thanks so much for your reply too

Have you installed Windows Phone SDK?
Have you installed Windows Phone Support Tool?
Have you installed Microsoft .NET Framework 4?
If yes read here ChevronWP7 Labs FAQ or contact support Chevron for solve your problem

Okay I'm still very new to windows phone 7, as I stated, I have wp7.5, os:7.10.7720.68.I have boot loader: 4.3.2250.0(128976). can someone please tell me how I would go about flashing a stock ruu? Do I have to mess with rspl/hspl yet? Please can someone help? I'm sorry for taking your time as well. Thank you much.
And also, sorry for being such a dreaded noob, but what application should I install for the bootloader mode when connect my surround in? Im on windows xp. Thanks again so much, I don't know what I would do without you guys.

Okayyyyy... a few things.
First. it looks like you're trying to use the original ChevronWP7 unlock. That tool is dead, and has been for over a year (it only worked on pre-NoDo ROMs). This is well documented. I'm not sure why people keep trying it... you'd think they'd read up a little before trying to use a hack on their phone.
Second. Why do you want to flash a stock ROM? (RUU = ROM Update Utility) In any case, the procedure is simple: turn the phone off, hold the Volume Down button, press Power to start the phone again. It'll boot to a screen with bands of color and yellow text. Next, connect it to the PC. You'll need the relevant drivers; Vista and up will install them automatically but for some reason you're still running an 11-year-old OS on your PC so you might need to install them manually (I think they are included with the Windows Mobile Device Center download from Microsoft). The phone should say USB at the bottom when it's connected; at that point just run the RUU program.
Thrid. RSPL / HSPL are replacement bootloaders for WP7. They allow installing custom ROMs. If you want to do that, you'll need to first downgrade your current bootloader; SPL 4.3 is too high for using RSPL. Since you're not on SPL 5.X yet, I think you can downgrade just by installing an older stock ROM or radio update. Otherwise, there are a number of guides for how to downgrade the SPL.

That's the reason I need to downgrade lol thanks

By chance, do you know the new way to unlock or do I have to flash a custom rom? Thanks

You are on a developer-locked HTC phone? The first option is to try getting dev-unlocked, for example by getting an AppHub account or a friend who has one. They're free for students (go through Dreamspark). The second option is to use a custom ROM. The third option is to wait until a new hack is found.
Once you're dev-unlocked, you can use the Interop-Unlock app from Heathcliff74 (the HTC one, specifically) to allow unlimited sideloading. Then, you can install WP7 Root Tools 0.9 to get nearly full access to the device.

Thanks so much. Will report back with results.

So sorry, but I did all the research I could and couldn't find an updated method of going through dreamspark. I registered and man I hate myself for this, but can anyone help me please?
EDIT: I am enjoying interop unlock on intrinsic ROM and I love it!!! Thank you all so much for your help! My next and hopefully last question is, is it okay to update my radio while I have hspl? Or do I have to ospl first thanks!

[Q] Downgrading / Interop Unlock for HD7 / Edit: Custom ROMs How-to Help

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
