Telstra Rom - not flashing

Folks,
HD2 from Telstra ( 2nd May ) running 1.66. Tried flashing it with 1.48 and 1.43 Rom's -- so I could then go to HSPL and a custom Rom, but no luck.
The Rom Update Utility starts and tells me I have image version 1.72.841.0, I click to update to 1.43.405.1 ( or 1.48 - have tried both ), then the 4 colour screen which notes 1.66. Then it goes to a HTC screen with a deployment bar, gets to only 1%.......then boom - error 294 invalid vendor id.......
What am I missing here ??

you need to flash thedowngrade from sd card, then you can hspl, and THEN flash from usb

At least your effort got that far.... i couldnt even see the zip open.
OS 5.2.21869
Manila 2.5.20121431.1
Rom 1.72.841.0
If someone can confirm what I need to do with what i'd REALLY appreciate it.
Have the backup rom just incase already.

you missed out all the important info.
what zip can't you open? what phone? what you trying to achieve?
assuming telstra like the op,
1 right click the telstra 1.4 rom .exe choose unzip here, or extract here
2 find ruu signed.nbh copy it to sd card rename it leoimg.nbh
3 phone off hold vol down, tap and release power, keep holding voldown till you see three coloured screen, should quickly change grey and start a card flash.
4 when complete and phone restarts hold vol down to re enter bootloader
5 run hspl as administrator using a usb port round the back of the pc,
6 when it completes, and phone reboots, enter bootloader yet again, and check that it says spl 1.42.hspl.
now, so long as you don't sd card flash hspl will stay and protect against bad flashes, flash what you like.

What 1.48 and 1.43 roms did you try? They need to be Telstra roms, as you can't just use any 1.48 or 1.43 rom and this is what is causing the invalid vendor id error. Once you are back to 1.42.0000 spl (after flashing a telstra rom) you can then run hspl and are then free to flash what ever your heart desires.

I have a Telstra HD2 as well (1.66)...got it recently and will flash it soon.
I don't understand the original poster's concern - why go through all that to flash HSPL, when apparently HSPL2 can be easily flashed over 1.66...which allows you to further flash any ROM ??? Is there a benefit of HSPL over HSPL2 that I am missing?
Thanks in advance
edit: my bad, just read in the HSPL thread that HSPL2 does not work with the telstra hd2.

keep reading, you still have lots to learn, hspl2 doesn't work on telstra.

Oh, my spl is 1.66.0000
I understand I must use HSPL (not HSPL2) on a Telstra ph. but can anyone recommend which rom to use? I've been reading for two days solid and can't decide!
I've copied all the guides etc so hopefully won't have a prob'... am just worried about warranty protection etc if it all goes pear shaped... i just want all this B.S. bloatware OFF MY phone!!!
Thanx in advance once again

I am in the same position, my Telstra ROM is 1.72 running SPL 1.66.0000.
HSPL utility tells me that "Model ID is invalid" or something like that.

okay, one more time.....
only the original hspl works on telstra,
hspl2 does not work. (bad model ID)
you need to downgrade to a 1.4 rom with spl 1.42.0000.
so, get the original telstra 1.49.8xx rom from HERE (registration required)
when its downloaded, move it to its own folder somewhere, then right click the .exe file and choose extract here. (if that option isnt available, install winrar)
when it has extracted, find teh file RUU_Signed.nbh, copy it to your sd card and rename it leoimg.nbh
restart your phone in bootloader mode, it should detect the leoimg.nbh and start to flash
this will reset your spl to 1.42.0000 and now you can use HSPL, and then flash any rom you like.

Thanks for the link to HTCpedia mate. I'd actually just found it myself by performing a thread search on the "Official HTC ROM's" thread. Downloading now.
Stupidly I've had problems after problems trying to get HSPL on my device. I actually started out on this ROM (1.49.x with SPL 1.42.0000). First I tried flashing from my Vista x64 machine, both HSPL2 and HSPL with errors, in my haste I thought I might need update to the latest Telstra ROM 1.72.x with SPL 1.66.0000 so I could use HSPL2 when in actual fact I just had the x64 USB driver problem, of course then the upgrade still didn't allow me to flash and made my situation harder as I had to find this original ROM again to downgrade.
Anyways I hope this works!

It works!
- flash rom back to 1.49.x with SPL 1.42.0000
- run HSPL with device connected via USB
- flash radio using CustomRUU
- flash ROM using CustomRUU

@rainey06au what Radio do you use with your Telstra HD2?

Got my Telstra HD2 running 1.49 last week and it's my first play with Windows Mobile .. couldn't wait to clear the Telstra image from the phone as my provider is Three.
Did plenty of reading and all the posts said to use the original HSPL first, this worked perfect first go.
Once done I tried the new Artemis_v110 rom, was very impressed except experienced 2 to 3 random reboots a day, even more while in YouTube player. Everything else woked well, reception, battery life, and clarity while on calls.
Decided yesterday to try another rom, first cleared all using Task29 format, then loaded HyperROM Ultimate v9.00 WM6.5.X but this didn't get through the first boot .. possibly due to radio required.
Now have flashed back to 1.48.4052 until I research some more.
Anyone recommend a rom and suitable radio for the Telstra HD2, anyone with Three?
Thankx

Thanks. Works a treat!
I knew I had to downgrade but couldn't find an old Telstra ROM.

I am also using Telstra HD2 and recently flashed it with Miri Rom. I like Miri because it doesn't have any customization. It has many versions to choose from, with and without Sense UI. It also retain all the original WM icons and themes which I like.
But like all ROMs, I do experience reboot but only once so far with the new version of Miri v17. One thing to note is the Radio version for the ROM. Make sure you flash the exact correct radio version, down to the sub version, e.g. 2.07.50 is recommended for Miri and not 2.07.51 (which is the Telstra radio version).
Another advise is always flash from pc, not SD card as I have experienced bad flash using SD card.
Hope this helps. Miri is only available from the HTCPedia site.

Yep my radio version is also 2.07.50. I get good battery life out of it using CleanEX_UDT HyperROM Ultra v9.00 (6.5).

I use Lia Glass ROM and FallOut Theme.
Interestingly this ROM and radio has only unlocked 455.54MB RAM, not the full 576MB. There are threads about this and getting the right combo will unlock the remaining RAM and/or improve battery performance.
I am using Radio 2.08.50.05.
Anyone else have the same experience?

look in settings about phone hardware info ram size.
I bet it says 576
that's cos the hardware takes 128 for graphics.
look st a standard rom and hardware will show 448 whilst total available will show 336

Thanks samsamuel.
Hardware info does in fact say 576MB RAM
Thanks for the explanation - slowly but surely getting my head around the intricacies of the device

Reverting ROM

I did a little searching around the forums but some of the answers posted to similar questions didn't really help, plus most of them were links to other threads.
Ok so heres my situation:
I recently upgraded to 2.13xxxxxx ROM from the T-Mobile HD2 website. Im having difficulty with the touch sensitivity and i have tried a cab file someone posted that tweaks the registry. I guess it worked but anyways. Since Flashing and tweaking i decided i want to revert back to the Stock 2.10xxxxx ROM that came with my phone. I plan on Flashing with custom roms in the future.
My question is simply, what do i need to do to flash my rom from 2.13xxxx back to 2.10xxxx with stock radio 2.8xxxxx. I have visited xmoo's thread with stock roms but im still unsure of what im doing since i just got this HD2 recently.
Heres some additional info,
Currently i run:
2.13.531.1 (90963) WWE ROM
ROM Date: 4/28/10 (Leaked?)
Radio version: 2.10.50.26
When i updated my ROM from 2.10 to 2.13 i use the USB Active Sync method suggested on the Tmobile download website. I didn't flash from the SD Card
EDIT: I went into Bootloader mode and what i see is this:
SPL-2.10.0000 8G XE
Does that mean anything?
I heard a lot of talk about doing something to ur HSPL and SPL or something, but i have absolutely no idea wtf people are talking about lol.
So if someone could give me the details as to how i can flash my rom back to stock, that would be helpful. And yes, i have read the tutorial about flashing your first GSM, still dont get it.

flash via SD card
I did the same thing and what you need to do is take this link and make a folder somewhere and right click on the winrar file and extract here to the folder you made and take the nbh file and rename this (LEOIMG.nbh) and place it on your sd card make sure its on the root of the sd card and not in a folder.Here are some instruction i used.Good Luck,ping33tx P.S remember that you will have to redo the spl and run the hspl again,once that's done your home free to flashing till you get tired of it,lol.
NOTE (PLEASE READ): If you flash a Stock Rom via microSD Card then it will overwrite your HardSPL with a stock SPL included in the nbh file. If you flash a v2.01 or later Rom (with SPL2.*) you will NOT be able to reinstall HardSPL onto your device and could end up bricking it. This does not apply to custom roms as they do not include an SPL. BE CAREFUL!!
1. Make sure your microSD is Formatted to fat32 (you dont have to delete all files but it is safer if you do)
2. Download your prefered Rom from the LEO Rom Develpoment Page and unzip/unrar it to your PC
3. Goto the Roms Folder and rename the .nbh file to LEOIMG.nbh
4. Copy the LEOIMG.nbh file to the root of your MicroSD Card
5. Plug the MicroSD Card into the phone
6. Reset the device while pressing the volume down button to enter the BootLoader screen, you will first see a tri-color screen with the phone and SPL Information at the top
7. Follow the On Screen instructions to start the update
8. After flash has completed, press the reset button with the stylus to reset the device

http://www.4shared.com/file/CRF3NcXL...V20_S2356.html

Thats awfully confusing for a first timer like myself. lol
And your link is broken... xD\
EDIT:
I did some searching and found some threads where peoples custom roms are BASE 2.13. Can i just flash those roms on my current version if i don't downgrade to 2.10? Cause if theres custom roms that works with my current version then im more than ok using those.
since im here, im a little confused with why some custom roms say, 6.5.5 or 6.5.X. Does that mean i need windows mobile 6.5.5 to use those roms or does it mean something else?
AND
Ive seen some custom roms that have a number like 23475 (for example), is that the OS build needed to run the rom or the Custom rom's build?
My current build is: 5.2.21892 (21892.5.0.89)
Thank you everyone for your help!

no, you always need hspl for custom roms.

that's the winmoversion used in the rom. 6.5.3 and 6.5.5 are updates to the current released winmo, 6.5
i think 6.5.3 is just about being shipped but .5 isn't official yet.
the big difference is the start button on the bottom of screen and slightly more finger friendly menus.
AND

that's the windows build used in the rom. 21xxx is 6.5 and i think 23xxx is 6.5.3, but there are more than three builds.

Almost the similar issue
I had a stock tmobile hd2. I never did any customizations to the phone or any kind of hard spl. Today I installed the tmobile official update that set my SPL to 2.10 making it incompatible with the hardspl tool.
I want to just flash a stock rom through the sd card, and revert the spl back to 2.08 so it can be compatible with the hardspl tool and then I can install the energyROM.
I downloaded the 2.01 stock rom from the rom thread in the leo forum, and right before I was going to rename the file and flash the SD card I read a post above saying that if I revert this back to a stock SPL version, and then try to run hardSPL, I will brick my phone. Is that true??
Suggestions??

flash 2.10.0 from sd card to reset spl to 2.08

You don't need to flash 2.10.0 from sd card to reset from 2.10 SPL to 2.08 SPL. You can flash 2.10.0 over activesync (using the .exe linked to in xmoo's thread) and the SPL will be reverted to the 2.08 version.

Thank you to everyone who posted and a special thank you to samsamuel for clearing things up. Maybe this thread will come in handy for people wondering the same thing.

Gonna move you over to General, also closing since issue has been resolved..

Tmobile HD2 hspl 2.10 question

Hello, i am new to the HD2 and i want to unlock it to install new roms. I checked my spl and i am running 2.10 and not 2.08 so the exe file that is given wont work. It says it is corrupt and it wont install. Is there a way tdowngrade the spl to 2.08 from 2.10?

Install the factory 2.10.1 ROM via your SD so that your SPL will be changed to 2.08. Then you should be able to use HSPL for 1024.

Yes, flash HSPL3, then run a Task29, then flash your preferred ROM.

Problem getting to spl 2.08 - please help
HI,
I've done my share of reading on this (my favorite) and other forums. Most recommend using HSPL3 for going back to SPL 2.08. I've tried that may times - unsuccessfully though...
Can anyone suggest what am I doing wrong?
==========
--- I currently have SPL 2.10.0000 8G XE
---I formatted the memory card to MS-DOS(FAT) (using disk utility)
---I am using ActiveSync....
---when I previously tried using HSPL3 I get to the screen where it should load to 100%, but never get to where it says "successfully hacked" or whatever it says when done; In my case it just loads up and then goes down... It can do that for hours if you let it.
Any help is appreciated as I am dying to see android running on this babe. Tx

[GUIDE] Downgrading SPL from 2.10.0000 (stock TMO) to 2.08

This procedure will tell you how to downgrade your SPL from 2.10.0000 (shipping stock now with TMO HD2) to 2.08 so that you may flash HARD SPL.
So for those who just received your TMO HD2's and want to start the process, this needs to be done before flashing HSPL and flashing custom ROMs.
1. Download this file:
www.2shared.com/file/MAsa78Yo/leoimg.html
www.megaupload.com/?d=VQ11Z040
2. Place the downloaded above LEOIMG.nbh on a 8GB or smaller microSD card (formatted in FAT32 is recommended)
3. Turn HD2 completely off. While holding POWER button also Hold the Volume Down button at the same time.
4. As soon as "Loading..." appears on the screen, release the Volume Down button. You will see a message stating how to proceed to flash the ROM.
5. The ROM will flash now. After its done your phone should reboot. Do a factory reset to clear out anything left over from previous ROM.
Now you should remove the SD CARD and reboot while holding the volume down button. On the tricolored bootload screen you should now see a SPL of 2.08. You are now ready to flash HSPL and then on to flashin all these great ROMs here on XDA.
Proceed to this great thread mskip put together on how to flash HARD SPL and on to ROM flashing: http://forum.xda-developers.com/showthread.php?t=653614

Yes, it has to be a 8gb or smaller. I have not tried a SD larger than 8GB personally. But, it has been posted in more than one thread that it is required.

hey.please can you double confirm for me that you can downgrade phones that shipped with 2,13 from spl 2.10.0000 to spl 2.08.0000 over usb?
did you both start from stock 2.13 (I.e neither of you had done any flashing of any kind before that first downgrade)
thanks

Give it a try, so long as you have a tmous phone, and you're trying tmous stock roms, it wont harm it.

From what I understand flashing via the SD card will assure your SPL wil be replaced (downgraded) properly. If you flash via the USB not sure if this process will complete properly. Im no expert but one thing I have learned from flashing my G1 hundreds of times, LISTEN TO THE SENIOR MEMBERS AND MODS.
It has been stated more than once here on XDA HD2 Tmo Dev section that you must flash VIA SD.

But a 16gb card wont worK? So I have to go buy a smaller one or wait for a updated hspl?

i downgraded and HSPLed my phone succesfully
thanks

I have a T-mobile HTC HD2 that had spl 2.10 which i received few days ago. I flashed a tmobile stock rom to downgrade to spl 2.08 through usb and installed hspl2 with no problem. You don't have to flash it via sd card.
Currently running Kumar's Rom V 2.0 with radio 2.10.50.26 (flashed radio afterwards)

SPL Downgrade help
I have a new hc hd2 and I attempted to downgrade the spl to 2.08.000 from 2.10 so that i could install HSPL2 1024. I attemted to downgrade via SD card and the spl downgrade failed and i am stuck at the bootloader screen after volume down reboot with, "Upgrade ROM code error, Please try again".. in the green area. Please inform how to fix, and get my htc hd2 back. Thanks Also i found out after the fact that it is better to do via USB, how would I do that when my phone is stuck? It also has RUUNBH in the upper right hand corner.

Last noob question. When you say you did it through usb, do you mean you just connected your device to the computer transfered the file to the phone and did the whole reset thing? Sorry.

Sorry after working with it more I figured out that since I was doing an SD downgrade that I cant have it charging via usb. I downgraded just fine after I unplugged from the puter. Thanks

[Q] Downgrading SPL 2.3 to 2.XX

Hi,
I have a HD2 that recently crashed and thought I would re-boot and have a go at installing WP7.
I have downloaded a few things and tinkered a bit without problems, but never cooked a ROM but seem to have fallen at the first hurdle.
I understand I need HSPL3 installed and to do that I need to downgrade to a previous SPL (I am on 3.03.000) and have tried both 2.7 and 2.10 from this site.
I connect the phone, unzip the file, folow the simple instructions and both the screen on the phone and PC start to do things and halt at 0%.
I have soft-reset and tried several times.
I am running ROM 3.14.405.2 unlocked to any network.
Have I missed something?
Thanks in advance.
PS - I did search the forum for an answer but didnt find one. Sorry if I missed it.

Assuming you have a Tmobile USA HD2:
Download and flash the 2.10.0 rom from this link, http://forum.xda-developers.com/showthread.php?t=655653 you will get 2.08 SPL which you can flash to HSPL.
But remember to flash a later version radio so as to be able to run android.
