Rom Flashing Question

Hey Everyone-
This post has probably already been answered but i have been searching the forums (and google) and getting mixed results.
I looking to flash the ROM on my HTC Touch Pro (Fuze). However, I've read that my phone must be unlocked to flash a new radio, but not a new ROM. However I've also read that with a new ROM comes a new Radio. So which is it? Do i need to unlock my phone to flash a new ROM because if not i will have a phone w/o a Radio?
Thanks alot, these forums are awesome.

From my understanding, you only need to unlock the phone if you want to use another device's radio. For example, you have a Touch Pro, if you wanted to put a Touch HD radio on it then the phone needs to be unlocked. However, if you want to put another Touch Pro radio on your touch pro you shouldn't need to unlock the phone.
To answer your second question about Roms with or without radios.... They come both ways but I have mostly seen Roms without included radios. Just read the desired Rom info page to find out if it includes a radio or not.

Unlock (HardSPL) is always necessary. No matter if u flash a radio, a rom or a radio/rom.
The only moment when u do not need to unlock is if u flash an official update , radio or rom, that is made from ur provider for ur phone. Or if its unbranded , the update is downloaded from htc itself with ur serial number entered befor.
BTW: Unlock (HardSPL) means that the loader of ur phone accepts NOT signed Roms or radio files for flashing.

Thank you both for the quick replies. So that i have this clear-
I can download and run hardspl according to the instructions etc, etc. Then if i choose to flash a rom without a radio i can. Then (or before) I can flash a Fuze Radio to my phone all without sim unlocking my phone?
Do i have that right?
Thank a million

Not shure if I got u correct in the first post:
By unlock do u mean SIM unlock ? Means use sims from any provider.
By unlock u mean entering the pin number to use ur phone ?
By unlock u mean (what I thought first) enabling the phone to accept any kind of rom ?
Normally a new radio is not always needed, I flash most of the times leaving my radio as it is, if its good in reception and power consumption

2. What are the different types of Unlock? (answer by DaveShaw)
The three stages of unlock are:
SIM: Allows you to use SIM's from another carrier. Can be done using codes or unlocker programs on xda-devs.
Security: Allows you to flash radios from another device (i.e. Raphael) - It does other stuff, but this is all the casual user will use it for
CID: CID unlocking is an old concept, nowadays you flash Hard SPL instead. This lets you flash any ROM, Splash or Radio (depending on sec unlock) to your device. N.B. the CID is the carrier ID (e.g. HTC__001). The stock SPL's only let you flash ROM's that match the CID in the ROM image with the CID on your device.
Also, SuperCID is an even older concept no longer valid on newer devices.

These are what I understand as the levels of Unlocking... so you're right. I was talking about a security unlock (my apologies). The carrier shouldn't have anything to do with the process. And i don't need special software to security unlock the phone right? (that's where i was getting confused)
As for that last part--
So assuming i like the reception and battery usage i get right now I can flash any ROM i want w/o worrying about losing the radio? And if i do get a ROM with a radio is the radio installed automatically or are there two steps? Thus enabling me to install the ROM without the radio that came with it?
Many Thanks

Ok, first u have to HardSPL (What does: Ur Phone accepts any radio and/or rom)
From here:http://forum.xda-developers.com/showthread.php?t=410150
NOTE 3: this is unsigned Hard-SPL. no limitations on flashing ROMs or radio packages. also, this has overwrite protection, if someone needs to revert to stock SPL for warranty reasons, we will soon post a stock SPL downgrade package.

If u have a touch pro and want to use Diamond or Blackstone radios then u have to do look here, first.
http://forum.xda-developers.com/showthread.php?t=426609
Then:
Flash ROM -> ur radio stays the same
Flash Radio -> ur rom stays the same
Flash all in one -> Both are changing, radio and rom.
Look in the roms thread, they tell u if it comes with or without radio. I think most of the times without. The original Raphael rom from HTC is WITH radio btw

Thank you very, very, very much!!!
Im gonna give this a try now.
Once again, many thanks.

Do you have it developer unlocked first?

HTC Have 2 OEM Update after Mango
if you updated your Phone with Second OEM Update, you can not Interop Unlock your phone

yes i have a dev account from app hub.

how do i find out if im running second oem? do you have the build number handy? the os version i have is 7.10.7720.68

It's not the OS build number, people. HTC controls the firmware number, not the OS number (that's Microsoft code). 7720.68 just means the RTM release of Mango. I swear, I write this so often...
If the third digit grouping of your firmware starts with 4 - that is, if your firmware version matches *.*.4XXXX.* - or lower, you can use the HTC Interop Unlock XAP. It *might* even be possible with *.*.50XXX.*, but I don't think so, and it certainly isn't possible with *.*.51XXX.* or newer.

well that helps a lot, ya my firmware shows 51004. so are there any workarounds as of yet?

The only work-around I know of is to downgrade. You can roll back a Zune restore point from before the firmware update(s) was installed, interop-unlock, and then reinstall the updates if you want (I've elected to semi-permanently keep my phone a few versions outdated on firmware). You could also flash a stock ROM that includes an older firmware. Be aware, however, that either option will lose some data - everything newer than the backup if you restore, everything on the phone if you flash a stock ROM.

Hey thanks for the information, I was wondering if there were any guides you can point me to on how to flash from a stock ROM. I have an HTC HD7.
Thanks again for your help. i know sometimes its tiring explaining the same thing over and over, but it is much appreciated.

Go to the HD7 ("Schubert") portion of the XDA-Devs wiki (http://forum.xda-developers.com/wiki). I'm pretty sure you can find the download links for stock ROMs there. You could also try the HD7-specific forum section. You'll download a tool called a RUU (ROM Update Utility) that will have some image files (extensions like .NBH and .NB) along with it. You put the phone in bootloader mode (four bars of different color - you have to boot the phone while holding the Volume Down button). It should have yellow text, and at the bottom should say "Serial". Connect the phone to USB. Your PC will need to install a driver (normally this will happen automatically, if not, use Device Manager to tell the computer to search Windows Update for the driver). Once the driver is installed, the "Serial" will be replaced by "USB". You can now run the RUU program.
I *strongly* recommend creating a backup first! The RUU will wipe all data on the phone, and if the flash fails for whatever reason, you'll be unable to boot the phone again.

Ok Thanks, That was helpful. i read a few guides and I think Im ready to try. i just wanted to ask a quick question before diving in. Hope you dont mind. Some threads make refrences to certain Bootloaders being unable to go through the downgrade process (by flashing a Stock Rom). Is this correct? My bootloader version is:
5.10.2250.0(132968)
If it doesnt matter than are there any other things that would prevent me from doing this process?
And one more question and I promise to leave you alone lol. I plan on backing up my phone before beginning, but if the flash fails for whatever reason and the phone is unable to boot again as you warned, will I still be able to connect it to Zune and restore my backup? Thanks again. Hopefullyone day I can give more to the community once I get used to it.

Booting the phone while holding the Camera button will put it in backup/restore mode. If you connect the phone to the PC while it is in this mode, and the Zune software is running, it should automaticlaly try to restore.
Your bootloader (SPL) version is too high to install HSPL (needed for custom ROMs), and it's high enough that it won't automatically downgrade just by installing a stock ROM. However, you should be able to install the other parts of a stock ROM (in particular, the firmware) just fine.
If needed, there are a couple ways to downgrade the SPL; search the dev&hacking sub-forum for info. I would generally recommend GoldCard, but that will require a little bit of equipment. Apparently, "SLSPL" flashing will allow you to downgrade the SPL safely as well, though I haven't tried it. These are mostly for preparing to install a custom ROM, though - stock ROMs should be installable on any SPL version.

it not work with my trophy verizon

[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] 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.
Sent from my HD7 T9292 using XDA Windows Phone 7 App

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

Need a couple of questions answered

Hi I recently fixed my HTC HD7 after a few months because my phone locked itself for no reason and my SPL was 5.1xx =.=, I just downgraded it using this method http://forum.xda-developers.com/showthread.php?t=1597837.

After so many updates that i missed I am now lost on what to do to my phone to get the lastest tango update. Please don't reply telling me to use the seach button because i've tried and I am not really good with this flashing phone stuff.
Can someone be kind enough as to link me and tell me instructions onto getting my phone back to an updated version.
My phone specs:
-HTC HD7
-SPL 3.xx
-Not full unlocked
-Not interop unlocked
-Nodo
I think my next step is getting a custom rom from DFT http://forum.xda-developers.com/showthread.php?t=1195647 but i can't seem to find the newest tango rom and what i should do to flash it on my phone.
Please help me !!:laugh::good:

The best place to get ROMs is from the phone-specific forums (in your case, the HD7 forums) here on XDA-Devs. You'll also need to install HSPA before you flash your custom ROM; the instructions to do that are on the WP7 Dev&Hacking sub-forum. Once you've got HSPL (make sure your bootloader version is right!!!) then you can install a custom ROM. The program to do this is called ROM Update Utility, commonly "RUU", and usually when you download a ROM it will come pre-packaged with RUU. If not, you can download something that doe come with RUU and replace the packaged ROM image files with the ones from your custom ROM.
