Hi, Searched without luck once again (Can Someone give me the Google Advanced search URL that they use to search the HD2 section?)
I am rather new to flashing and would like to flash to Radio 2.08.50.08_2 from http://forum.xda-developers.com/showthread.php?t=632833. I have the following file for the flash: RUU_Leo_Radio_15.34.50.07U_2.08.50.08_2.exe
My two questions are:
1: Can I flash just the radio without installing HSPL?
2: If not, Can i revert back to stock SPL after flashing just the Radio ROM?

1) No unless it is made for your specific region which in this case it is not.
2) I wouldnt advice it, why would you need to do so?

Yes, by sd card flashing your original stock rom BUT in doing so you would also flash back the original stock radio.
I'd install HSPL, flash your radio, and then only flash back to stock should you ever need to remove HSPL.
thanks
Thanks for the replies. Thought I should revert to the stock SPL coz I'm scared I forget to reflash should I need to send it in for repairs.
But I suppose I just gotta make a long lasting mental note to do so. Whats the best method of flashing the radio with HSPL? SDCard or PC?
(I am using a zip file with an nbh and a custom RUU rathere than the exe stated above)
stay away from sd card flashing. Theres no need, and it isn't so safe (opinion, im sure there are plenty of people will tell you otherwise, heh).
Instal HSPL, flash the radio from USB, reboot, job done, forget about HSPL even being there unless you need to return it, in which case flash the stock rom from sd card and hspl is gone.
unzip the nbh into a folder(maybe rename it RUU_Signed.nbh, i forget), copy customruu.exe in there too, run customRUU.

Actually flashing JUST the radio via microsd card is a very fast and efficient way of doing it as long as it is just the radio image and nothing else. I used to travel quite a bit and had different radios that worked better in different countrys so I had them all saved on my card and then when you want to change radio you can just rename it to LEOIMG.nbh, move it to the root of your microsd card and enter bootloader to flash.
Flashing via microsd card is in essence alot safer as long as you stay FARR away from stock roms.
I would advise you to keep HardSPL on your phone for as long as you can. Its like having a get out of brickville card just in case anything goes wrong. The only way you wouldnt be able to flash back a stock spl is if the screen broke or you dropped your phone and I dont think its going to be covered by warranty then anyway lol.

I tried a few cooked roms and I like some things about them and others I dont, so I was going to flash my phone back to stock and if there are any upgrades/updates I would like to do so also.... Please advise me, should I do this why or why not... and How can I go about doing this ? (Would I just use hspl2 1024 and reinstall 2.08 first, then install the latest stock rom ? -but where can I find the latest official stock rom?-can I get it from htc? )....
thanks in adavance...
If you have already run hspl2 there is no need to do it again. All you need to do is download the shipped rom (available here and at ppcgeeks.com) and flash it. There haven't been any updates for the stock rom as of yet. Your personal choice on if you want custom rom or stock. Custom roms usually have less bloatware and performance enhancements that make them ideal over the stock rom.

looking for help
I installed hspl 2.08.0000 and flashed a custom rom, then I tried to flashed a vodafone Uk shipped Rom and now my Hd2 won't even boot up, when I connect it to the usb windows xp sees the device and tries to install a driver but then fails to find a driver. I cant even use mtty because usb is not listed as one of the selections. does anyone know how to help Please
Could be because you flashed a shipped rom that is for a different device. The european HD2 is different than the US HD2. If you have a US HD2 flash a rom that is designed for 1024 Leo (recommend Miri and Steve's Eleganicia). Put the phone in bootloader and then flash from pc or you can rename the .nbh from a rom to LEOIMG.nbh and place that in the root of your storage card to flash. Can get to bootloader by holding volume down and pressing the reset button under the back cover, holding vol key til tri-colored screen appears.
it wont let me get into bootloader mode, my computer does see the hd2 but wont let me access the usb
Maybe someone else can chime to correct me if im wrong but sounds like you now have one expensive paper weight. Flashing a rom that is not for your phone is not good.
Flashing a Euro Rom on your TmoUS HD2 will brick your phone - for good. Why are so many people doing this?
tmo are sure to get wise to this and stop replacing them at this rate. I've seen 6 or 7 people with the same problem in two days.
Guys with a tmous,
1 - DONT flash any stock roms except the one from tmous. Stock roms include a radio and it will kill your phone.
2 - DONT flash any radio with a .51. in the version. It will kill your phone.
3 - dont flash any cooked rom not based on the 2.10 rom. It will kill your phone. (i think, , , possibly recoverable, not sure yet)
4 - most of all read first, flash later.
OK PLEASE do not hijack the topic,
Remember I asked how can I reset my phone back to completely stock (like when I first bought it).... and then after that I would like to update it (if there are any updates)....
Thanks for all the advice so far...

2 ways.
1 - connect phone via USB, run hspl1024, choose spl 2.08.0000, thats your spl back to stock. Then flash the tmous 2.1 rom over usb, thats your radio and rom returned to stock.
2 - you can get the tmous 2.1 rom, extract the file ruu_signed.nbh, copy it to sd card, rename it leoimg.nbh and reset your phone, which will see the nbh file and flash it, and because it is from sd card it will also reset the spl (and radio) to stock.
i'd go for option 1, as i haven't read much about people flashing sd card on the tmous, so for now steer clear.

it's the spl that voids the warranty, not the rom. when you boot to bootloader, so long as it says
spl 2.08.0000
then you are good to go.
Thank you!
Sorry if this has been posted already, but I'm in a hurry since I'm at work. I need to get a replacement phone from tmobile, and I'm pretty sure that since I installed Elegancia, my warranty is voided. What all do I need to do in order to get everything back to normal?
I'm not sure but you must use the same tool. to unistalled. HSPL2_1024.run. to revert it. 2.08.HSPL to 2.08.0000. and then flash to original rom.
Or flash a stock ROM (found in the stickies) from your SD card. That will overwrite the HardSPL. But don't use the 16GB card that came with the phone. It will usually not work using that card. Format a different (preferably class 6) SD card and copy the stock LEOIMG.nbh file to it and flash from there.
or just flash it to the stock rom via USB cable. Pretty much the same process you used to flash to the custom rom you have now it's the exact same thing when flashing to stock rom. Look in the HD2 Tmobile ROM section and get the latest one. That's all you need.

From what I have read and understand, this is bad information (although I haven't actually tried it to verify that it would work or not). From all of the information that the experts have provided in theses forums, you need to flash the stock ROM from the SD card in order to overwrite the HSPL. The HSPL would not be overwritten if flashing via USB and active sync.
i got my replacement and i sent my phone in with a custom rom.
but to go back to stock it's just like you setting up a custom rom, find the original rom you want there are 2 that's out for the phone( the one shipped and the update) and your all set
i just sent in my custom rommed phone also, they didn't care.
theunlockr.com/2010/04/22/how-to-get-the-htc-hd2-back-to-stock
I have a very strange problem and if anyone could help me I'd very much appreciate it as I can't find anything similar in the forums (with a solution) after a month of searching.
My HD2 has HardSPL3 and the ChuckyDroid ROM with Android on an SDCard.
The USB connector on the handset has stopped working (the metal D-shape thing wobbles about) so I cannot flash a ROM to it via the ROM Update Utility, only by the LEOIMG.nbh on an SDCard method works.
I need to send the handset back to Vodafone for a warranty repair, but obviously having HSPL3 and a custom WM ROM invalidates my warranty so I need to flash the stock ROM back to the phone to remove them both.
Problem is that I can flash any custom ROM I find to the handset using the SDCard method (Except Energy ROM's for some reason) but when I try to flash the stock Vodafone ROM using this method it fails to start the phones flash routine.
So I'm stuck with a phone I can't charge (using desktop charger for the battery atm) and I can't send back for repair.
Any ideas?????
Thanks in advance!
dont worry too much about the rom, get a close to stock custom rom on there, use hspl2.exe to remove hspl (set it to 1.66.0000) and it should be fine.

Is it possible to flash HSPL2 onto it without using the USB cable?
The connector on the handset is totally borked so i can't use the PC for anything, just the SDCard flashing method. :/
**BUMP**
I haven't found a solution still.
no, you cant use any other means to run hspl.
as to why custom roms flash from card and stock dont, you must be doing something wrong. please outline your proceedure.

I downloaded the stock Vodafone ROM from the link in mskip's flashing thread.
Rename the .exe to .zip
Extract the zip
Rename the RUU_Signed.nbh to LEOIMG.nbh and copy it to an SDCard.
insert card into handset and reboot holding the volume down button.
Same procedure I use for flashing custom ROM's.
hmm, very strange, all i can suggest is trying several different stock roms. dont forget to check what your bootloader says for spl, because even a failed stock flash can remove hspl and reset stock spl.

I downloaded the ROM directly from HTC support site but same thing occurs when I try to flash it. HSPL is definitely still on there too.
I find it weird that I can flash any custom ROM except the Energy ROMs, I'm assuming that perhaps these have more in common with stock ROM's than the others.
I'm lost atm!
a long shot, but are you extracting the ruu_signed before copying it to the sd card, or are you drag/dropping it directly to the phone from within winrar/winzip? I've heard of that causing problems with corruption before, though I can't remember the files involved or the context.
try different stock roms, you said its voda, but was it locked voda?
appart from that, thoughts would be, make sure the sd is freshly formatted, full format, not quick format, fat32, get the roms from different sources, maybe even use different browsers to download them, maybe even try the wwe 3.14 rom, even if it flashes the spl and then wont load the rom, you can always plead ignorance with them, it's a stock spl after all. (Course, they may just tell you to do one, so only try that if you are prepared to argue)

I've tried two different downloads of the ROM (htc.com and the one in mskips thread) and two different sdcards, the 2GB that came with it and a Class 4 Kingston. I'll try formatting both cards using the sdcard.org formatter in Win2K and see if that makes a difference.
My desktop charger has now decided to die on me so I can't try anything until my new one arrives from Hong Kong in a week or so. :/
mod: If this should be in DHD General, please move it
At the moment, sometimes current RUUs (ROM Update Utility) do not flash from the latest RUU exe - many times it will not recognise the Desire HD.
If you are having this problem, this is how to flash the latest stock RUU.
The latest RUU at the time of writing is 1.32.405.6.
You can download the RUUs from xmoo's thread or from mousey_'s site.
note: This is mainly for stock phones, for vendor-derived ones (e.g Vodafone DHDs in Australia) you will also need a goldcard.
Common Steps
Download the latest RUU (1.32.405.6).
Run it as administrator.
Tick the 'I understand the caution indicated above...' box, and click next.
At this point do not go any further.
Navigate to C:\Users\Ivo\AppData\Local\Temp (Replace my username with yours; AppData is a hidden folder)
You should see one or two folders like this:
{719CE201-7B12-4A13-9AF6-8F359FE69C7B}
Go into the one with dotnetinstaller.exe in it.
Open up the next folder.
Copy rom.zip into another folder (outside of temp).
At this point just Cancel and quit out of the ROM Update Utility.
A) Install through PC
Download and install HTC Sync 3.0 and restart.
Download the 1.15.405.1 Test RUU. It is the only one currently known to find the Android DHD.
Start it the same way as before, get to the
1. Connect the Smartphone to the USB Cable.
step. (but no further)
Again, go to the AppData local temp directory (same as above), and find the folder with dotnetinstaller.exe and inside that, rom.zip
You want to delete the rom.zip (which is the 1.15 version) and replace it with (copy back) the 1.32 rom.zip you copied out earler.
DO NOT UPDATE WITH 1.15 ROM, IT IS NOT DESIGNED FOR RETAIL DHDs.
Now click through the next buttons.
The 1.15 Utility should now be set to update with the 1.32 rom. You will see the version number of the rom at the final step.
Click update and watch the magic happen
B) or Install through Phone
With the rom.zip you copied out earlier, rename it PD98IMG.zip
Copy this onto the root of your microSD card through some means (disk drive, ftp, wireless).
Restart your phone and boot into the bootloader by holding power and volume down at the same time as it restarts.
It should go into the bootloader, take a fair while to check the zip on the sd card, and then ask you if you want to flash it.
Say yes!
Hope this can help some people for whom the 1.32 RUUs aren't working for them
Thanks for putting up this post! I was about to request one last night.
Now if only there could be a similar guide to flashing custom ROMs
To force unroot, I could reinstall RUU 1.32.405.6 from Win7 without problems, a bit longer than updating/reinstalling a WinMo 6.5.x rom (my former HD2), but it went through...
Thanks Ivolol this worked a treat
Appreciate your guide and efforts.
I am running Win 7 64. folowed 1.15 method now running latest 1.32.405.6

Weird; I tested a couple of RUUs (not as many as xmoo did) and all of them couldn't connect to my phone (whereas 1.15 could).
It'd be interesting to find out what the factors are that cause this. ATM the guide above is what to do if someone finds themselves in the same situation (the current ROMs won't find the phone).

+1 here, went through the normal RUU process fine just for ****s and giggles. I've extracted the ROM.zip though in case it's needed for future use.
sorry for the noob question..just had my DHD for the last 5 days. I come from galaxy S, and in there whenever we flash a rom all the data gets wiped out.
is it true also when we flash a RUU??
also if I do that...would i still be able to get OTA updates??

I haven't got complete knowledge of the entire subject yet, but:
a RUU will completely wipe all user settings / apps. Won't do anything to the sd card though.
An update.zip is akin to an OTA update, it does not wipe user settings.
Flashing with a stock RUU will mean that you can still get OTA updates.
I've tried using the phone method and unable to flash successful. I believe you need a valid GoldCard to use this method.
Can you confirm if the GoldCard is required for doing it with the phone method?
In addition, once the unit (especially our Voda branded one) is flashed with the latest ROM, OTA may not run properly which will result in disabled functionality (as recorded in this thread: forums.whirlpool.net.au/forum-replies.cfm?t=1575514, wifi stopped working). Theory said you'll need a GoldCard to get OTA to work properly (from another thread in XDA).
Thanks.

There is a big reason I decided to buy my DHD outright and not through Vodafone
I'm pretty sure that Vodafone's OTAs will be different from HTC's. In order to get OTAs from Vodafone you will need their image on it.
Also with vodafone's ROM installed, I wouldn't think it would accept HTC's vanilla ROM/RUU without going through the entire root process (it would only accept Vodafone signed ROMs). So in order to get onto HTC's ROMs I would think you need to follow http://forum.xda-developers.com/showthread.php?t=841076 before the phone will let you run a HTC RUU on it.
I haven't explored goldcards as I personally have no use for one, but you might also need one by the sounds of it for the Vodafone ROM to let you replace it. (edit: yes it looks like you need one to officially flash from a Vendor ROM to a generic one.)
So this guide is mainly for people with vanilla HTC phones. Although someone has posted a stock rooted Vodafone ROM on the phones so you might be able to use the same techniques outlined here with that.

clockwork mod is useful but not entirely necessary. You might be able to use this guide's method to flash a custom ROM onto it (haven't tried yet), but otherwise I think what you need is a recovery img that will let you upload custom/unsigned ROMs onto it. And also S-OFF I imagine.
ok so i have S-OFF and clockwork mod recovery...
if i have the rom.zip and rename it to PD98IMG.zip and run bootloader.
i shouldnt have any problems flashing this rom??
BTW am using Aus branded Vodafone HDH.
also..IF i flash this rom..would i loose S-Off and clockwork recovery mod??
would flashing this allow me to gain OTA???

If you flash a stock RUU rom.zip then you will loose all custom apps, data, s-off, recovery, etc. It puts it to factory settings. If you are in the business of flashing ROMs then I wouldn't worry about OTA because the developers here will integrate HTC updates as they come out, if they come out
However yes I think if you flashed a stock RUU then you will be able to get OTA. You might still need a goldcard, I'm not exactly sure.

An RUU is an exe which contains the stock 'firmware' from HTC to flash to your device. Basically it will do a full factory reset of your device. It won't wipe your sdcard but it will overwrite everything else.
it didnt asked me for anything on option B) or Install through Phone. i didnt get the option to flash it.
