hi all,
tried flashing a stock ROM (RUU_Leo_S_HTC_WWE_3.14.405.2_Radio_15.42.50.11U_2.15.50.14_LEO_S_Ship) via SD card and now ive got a ROM code error and 00028002 'Not Allow" error.
the phone is hd2 eu and it still connect via usb to pc, tried to flash HSPL4 to change SPL 3.03.0000 to HSPL with no luck, tried to flash via sdcard and pc with no luck.
after looking around the site, i found that i should try the official ROM for my device but can't find where to enter the s/n on HTC.COM
my s/n is: SH08SNW02573
THANK YOU FOR YOUR TIME.

I had what I believe is a similar problem: I couldn't flash anything at all. I freaked out because nothing worked, but eventually I fixed it using HSPL4 to put SPL 2.08 (or whichever), then HSPL 2.08, and I could re-do the process from there.
I don't remember all I did and all I read, but what I remember is that although this solution sounded stupid because I alreay had HSPL, it fixed it.
Good luck.
From where did you buy this phone and what's your carrier?
i bought the phone in lebanon in meddle east, it's on alfa network and the phone in factory unlocked.
i can't find where to to enter the s/n of the phone on htc.com site.
HTC replied to my email about the s/n :
'Thank you for contacting our Customer Support Center.
With regards to your inquiry,
Kindly note that the provided serial number “SH08SNW02573” states that your device is from ‘India’. Accordingly, you need to select the country as “India” when you log into HTC website in order to receive the updates compatible to your device."
so i'll download the rom and try.
thank you all.
i downloaded the rom from htc/india, now the flash start but stuck on 80% with error 00018002 error updating hd2 rom.
Did you flash it via PC or via SD card?

Hi, I just got my HTC HD2 back from repair. Before I sent it, I had a problem reflashing to stock rom before sending it in, and stock HSPL... when I turn the power on, all I get is a white triangle with an exclamation mark in the middle...i thought if i sent it in like that, they would help me restore it but they didn't....how do i get my phone to work again ]:
enter bootloader, flash a compatible stock rom. phone should be fine.
whilst in bootloader take note of what spl says.
Everytime I try to flash a ROM, it gives me the ERROR [294]: INVALID VENDER ID error...
right now my phone is stuck on the bootloader screen...it says
HX-BC
SPL-1.42.0000 XE
MicroP(LED) 0x05
MicroP(TOUCH) 0x40
and if i take out my SD card, when I turn the power on, i get the triangle exclamation mark ]:
I take it its a stock rom you are trying to flash?
I'm not positive which is the stock rom for my phone. It's the HTC Leo HD2 T8585...I remember it being 1.66 but i'm not positive. I downloaded
RUU_Leo_HTC_WWE_1.66.405.2_Radio_Signed_15.30.50.07U_2.06.51.07_Ship
still the same error :|
i also tried
RUU_Leo_HTC_WWE_1.48.405.2_Radio_Signed_15.28.50.07U_2.05.51.05_2_Ship
and
_HTC HD2_RUU_Leo_S_HTC_WWE_3.14.405.2_Radio_15.42.50.11U_2.15.50.14_LEO_S_Ship
all give me the same error :|
The Invalid Vendor ID error means that the rom you are trying to flash is not meant for your phone and the ones you are using are for a different vendor/operator/area than the one who supplied your phone. You either need to find the correct rom or else you need to install HSPL in order to flash any rom you wish.
You current spl is 1.42.0000 so trying to flash roms based on 3.14 will definitely not work as will most of the 1.66 based roms, as unless you use HSPL the rom needs to match the spl version on the device.
Try looking here and concentrate on the 1.48 or 1.43 roms
You can of course also try going to the HTC site for your area, entering your device S/N and try to download the rom for your device.
I just finished downloading and tried
RUU_Leo_HTC_WWE_1.43.405.1_Radio_Signed_15.26.50.07U_2.04.50_22_2_Ship
and
RUU_Leo_HTC_WWE_1.48.405.2_Radio_Signed_15.28.50.07U_2.05.51.05_2_Ship
...no luck..
i also went on HTC site..tried 4 different rom updates but when i enter my serial it says "Sorry, this software download is not suitable for your device" for all of them...
if its any help, it was like this because i remember doing something with using my SD card and taking a file and changing it to LEOIMG.nbh...
forget all that, and forget what i just sent you in PM.
you have spl 1.42.0000, so, get hspl2 (see lilnk in my sig) enter bootloader, run hspl2.exe (right click it, 'run as administrator')
choose, say, 1.66.hspl (it will automatically offer you 1.42.hspl, you can change it in the dropdown, or leave it as 1.42.hspl, it really doesnt matter)
when the phone restarts, quickly press and hold volume down, the phone will re-enter bootlader, flash a rom, any rom, over USB, so long as it isn't a 3.14 rom.
report back.
ah crap... I got everything working again after installing HSPL again before you posted...then i flashed a rom...and realized that HTC didn't fix my touchscreen problem so I have to send it in for repair...AGAIN. so I tried to remove HSPL AGAIN so I don't void the warranty...now i'm stuck at almost the same situation except it says SPL 3.03.0000
...and now i get a exclamation mark with a traingle but this time, under it, it says "Software update failed. Please try again."

well, that will be fine for warranty, because its a stock spl.
Basically, it sounds like what you just did was use hspl to flash the 3.14 rom from sd card, cos that lets the flash start, but it applies spl 3.03 which then checks teh rom and finds it doesn't match, and so fails. If hspl wasn''t there, it wouldn't let you get even that far.
So, you have spl 3.03 and no working rom.
You need your actual stock rom, not just 'a' stock rom, (im not scrolling to see if you posted it yet, but if its operator branded, you gotta get the right one) doesn't matter which version, 1.43, 1.66, 1.72, whatever. get that and flash it. USB should be fine, but if it fails go for leoimg on sd card.
Failing that, if you can get hold of another working winmo phone for afew minutes, you can probably revive it (and indeed flash teh 3.14 rom if you like) with a goldcard.
EDIT - oh, does your phone only work with one sim? if so, your first stop would be try teh branded one for that operator.
I think I'm just going to leave it if it's fine for warranty and call HTC to ask them if they can reset everything for me...i don't want to mess it up even more ]:
ahh well theres the unknown see, , cos in theory the only way you can GET that stock spl on your phone is if you have been playing with hspl (or maybe if you're an electronics engineer / 1337 mobile hacker, heh), , now if they want to be funny, perhaps they could call your bluff, , , no one has reported anything like that to my knowloedge, and it doesn't break any unauthorised software rules, so who knows.
i don't remember which one my stock rom was...i THINK its 1.66 but its not working... :\..
I bought this phone in China seperately without a contract so its unlocked/not branded.. its the T8585 model...
that's why you need to spend some time on the htc website, try to download roms using your serial, when it lets you have one, that will tell you your original stock.
When I enter my serial, they all say "Sorry, this software download is not suitable for your device"... \:
hehe, , then you are on the wrong htc region website. all the roms are there, somewhere.
could always phone htc and ask them which is the stock rom for your serial.
Nice, okay, the 1.66 that I downloaded from Middle East & Africa-English Country on HTC site worked after entering my serial...Now I have SPL 1.42.0000 .
Now I just gotta wait another 2-3 weeks before I get my phone back from HTC ]:
Thanks for the help! Appreciate it.
I had stock 1.66 and I tried install 3.14 stock. I download ROM form HTC page after giving serial number.
All flash process on PC was done correctly, on PC was that flash is finish (it goes to 100% and then I can put only Finish) but on phone I saw only SPL 3.03 after a longer while I decided to reset phone but after reset there is still only SPL 3.03, when I tried install ROM again but it always goes to 1% (HTC logo on Phone is strange, has strange lines on it) and I have error on PC Invalid Model. I tried install older versions but situation is the same.
Is there any possibility to force install ROM in this case or phone is permanently dead now?
on bootloader screen, what does the model ID read as? (top line)

It kinda sounds like you downloaded the wrong stick ROM. Who is you carrier? And what model HD2 do you have?
Dear Dev's / members
I have problem with this HD2 and cannot find a solution yet!
first thing first. is this a Tmobile of Eu mobile?
i tried flashing factory RUU but after 1% it gives an error saying Radio failed.
tried flash quite a few radio's but still after 100% it says radio fail.
tried flashing from USB cable
tried flashing from SD with leoimg.nbh
no luck.
the guy was using android on it until yesterday. may be he tried to flash a wrong Rom which brick the phone. now only white screen appears.
i can go to bootloader mode but no luck in flashing any thing at all.
Looks like EU model as no logo near earpiece.
if also has white markings on call & end key that would help confirm EU.
If trying to install .nbh file from SD it will overwrite HSPL so check current SPL status in bootloader.
If still on HSPL 2.08 try flashing an NRG WM6.5 ROM & see what happens (they have no radio so if completes then try radio flash if needed, try via USB them SD if USB fails.
Do you get an error code when it fails via RUU ?
thanks for helping mr. B
the error i get is (270) and yes it have white markings on all the buttons. so its confirm EU model. by NRG rom you mean Energy Roms? i tried earlier the energy Rom but no luck. after 1% it gives error.
cannot try mtty method as i'm on windows 7 and in windows 7, it's not showing the USB port. it's radio is corrupted. i think someone must have flashed a wrong Rom.
What standard ROM have you got ? if it a 3.14 rom try connecting HD2 via USB & use HSPL4 toolkit to install HSPL 3.03 & if that installs then try the 3.14 ROM via USB & RUU.
Also eliminate simple issues such as lead & USB port by switching port & using a different USB lead.
Windows 7 64bit ? worth trying another PC & 32bit if can as WMDC drivers on 64bit can be a pain for flashing ...
windows 7 32bit. tried flashing hspl 4 and it says complete but in bootloader it shows 2.08 only. i guess gold card method will solve the problem but it's too complicated. any other suggestions?
i would search for task29 and format the phone back to virgin default then download a windows rom from htc via the downloads page on there website for the phone ,then if it works re task29 it then put android on it with the htc hd2 tool kit witch has every thing other than rom (all u need to do is task29 it then go back to the boot loader and run the ruu rom)

No do not run a Task 29 the device. I say this for two reasons, one if you flash the Stock Windows Mobile ROM via RUU the RUU will run a Task 28 before installing the ROM witch is pretty much the same as a Task 29. The second reason is that if you run a Task 29 it will remove the current ROM on the device so it will not have a working ROM anymore. If after the Task 29 you can not get another ROM installed on it the you will not be able to use the device at all anymore.
why not he thinks its bricked so there is no difference if he cant get a rom on it

No the device is not bricked, a bricked device will not even turn on at all, no vibrations no nothing.
At jacktackle, try to find the earliest stock Rom RUU for your HD2 and try to flash it. It is possible you have what is reffered to as a stuck radio.The only fixI have seen for this is to flash a older ROM version with a older SPL version. If the earliest ROM version does not work start working your way up one version at a time and you might get lucky and get one that will flash.
thanks for all the help guys. but nothing worked. tried flashed old ruu's but reboots at 1% this radio is screwed up. hspl 2.08 is not upgrading nor downgrading. sd card update not working. i guess thats it. will give it back to him so that he can showcase it
first time ever i'm un successful. bad luck! may this LEO rest in peace. 'amen'

Before you give it back you can find some of the old test ROMs for the EU or for the TMOUS depending on which version of the HD2 it is. Just make sure if it is a TMOUS that you do not flash a rom version that has a 51 radio with it. Just look at the RUU name and the radio version is in the name. If that does not work then the only fix will be to replace the mainboard cause JTAG would not fix the problem.
Hi everyone!
I am very sorry for such a n00b-post, but I really cannot find a solution.
The problem:
I recently got a HD2 of a friends who did not use it anymore, because Android suddently stopped working. Now it's stuck at a black screen [A] saying:
aMAGLDR V1.13
Build: Feb 1 2011 03:46:07
by Cotulla 2011
I tried resetting the phone using the red button near the battery, but it did not solve the problem. I am able to boot the HD2 into recovery-mode (colory screen) but then, after connecting to a pc it does not change from "serial" to "usb".
I have installed WMDC on my W7 64-bit system. I have also tried to use "RUU_Leo_HTC_NLD_1.66.404.1_Radio_Signed_15.30.50.07U_2.06.51.07_Ship" (from the 4shared "shipped LEO roms"), but none of them recognises my HD2 neither in Recovery nor in the black screen [A].
Is this phone useless? What can I try to revive it?
What might be helpfull: when normally booting, the phone vibrates once during the HTC-screen and 5 times after the black screen [A] appears.

Since you're unable to connect to PC, then you can't re-flash HSPL.
HSPL needed to force flash any shipped WM6.5 ROMs to HD2.
Then the only way is to flash original WM6.5 ROM for your device from uSD.
If you're not sure what CID, just download any HD2 shipped ROMs and try to flash from uSD.
Just be careful not to flash EU's ROM on T-Mobile device!
Extract the ".exe" file, then rename the ".nbh" file into "leo.nbh", copy that to root of uSD.
Power up your device while pressing vol down button.
Don't worry if the ROM refuse to flash, it's just a wrong CID.
But to make sure, connect your device to another clean PC (without android drivers inside, just WMDC), preferably a PC sets for syncing WP7/WP8 devices.
And make sure your device turns on by itself when charger is connected (auto turn on from off state).
That's just to make sure that usb connector is not damaged.
HD2 vibrate 1x at power on, it's normal.
Vibrate 5x after magldr shows up, I suspect something wrong with magldr or the ROM itself (corrupted or something).
Another possibility is some NAND bad blocks.
But if it's vibrate 5x at power on, then you have a bad luck.
The point is, flash the original ROM first.
If it's success, then flash HSPL.
After that, the rest is up to you..
Firstly, I want to thank you very much for your quick and extensive answer!
But I have only one tiny question: are these the ROMS which I can find at http: //www . 4shared . com/dir/22189940/b8552fa0/Shipped_Leo_ROMs.html#dir=MGRa1Cen ? And you mean I should just pick one and try?
You can also find HD2 shipped ROMs here.
Anything that has "TMO" are T-mobile ROMs, otherwise it's EU.
Again, don't flash EU's ROM on TMO devices!
The first 3 digit are the ROM version (1.66, 1.48. etc.), 3.14 is the latest WM6.5 ROM.
The next 3 digit are CID code (207, 404, 707, etc.).
Like I've said, if you don't know which CID for your HD2, then just download all ROMs from different CID then flash it one-by-one using uSD.
Thanks!
So far I have tried the 404 and 162 (edit: and 161, 911), but so far without luck. I'll keep you posted!
Tiny question: is it normal that I cannot shutdown in Recovery Mode?
Perhaps some useful info shown in Recovery:
PB81100 HX-BC
SPL-2.08.HSPL 8G XE
0x05
CotullaHSPL 0x40
Correct me if I'm wrong, but it looks like an EU HD2, TMO HD2 are rarely using hynix nand, made around late 2009 or early 2010.
Just try to flash ROM with CID for your friend's country first.
If failed, then try another CID.
There should be one or two info about CID number vs. country somewhere around.
Good luck!

At this moment I have tried all the NLD roms with no result. Also I have tried roms from several european countries, but none of them works:/ Might it help if I give the serial number?
And what might be worth saying: my phone turns on when connected to AC power / wall-charger; when connected to charger the "serial" disappears...
Thanks for all your help!!!
Have you try connect to other PC?
When flasing ROM from uSD and failed, what error message you got?
If it's "CID mismatch" or something like that, than it's definitely a wrong CID.
If it's "ROM update error bla bla bla", it's most likely corrupted flash image or the uSD itself (use a small sized uSD, 1gb would be fine).
Even if you flash the correct CID, without removing HSPL first, it would still throw an error message "ROM update error bla bla bla" during flashing Radio.
Then it will restart and retry to flash again on it's own.
By the way, I don't know if there are ways to flash HSPL from uSD.
Or guide on how to make a "gold card".
I sugest you search it.
Worth to try if you couldn't find the correct CID for your device.
CID from serial number?
Yes, back in 2010/11 HTC site provides s/n checking for download the correct ROM.
But now it's gone.

Thank you very, very much for helping such a newbie ^^
At this moment, I am able to get into the update-menu: I changed the filename to LEOIMG.nbh. The only problem is that all the Dutch images give the same error: 00018003 : Radio (V2) - FAIL.
What could I do to solve this error? Use the freezer-trick or wouldn't it make any sense?
edit: it does boot when I connect to another W7 pc with WMDC (replies " Not connected" ), only it automatically starts the update-procedure (which fails).
There are no such thing as newbie, that's why we need to learn.
Error 00018003 during Radio flash?
I have no idea what error is that.
But first, are you sure that your friend bought the phone on local shop?
I mean, not imported, or when he/she travel overseas, or has the mainboard swapped at HTC service center.
It happens to me when my second HD2 suddenly has no signal, about 2 years ago.
Brought it to local service center and they swapped the mainboard without telling me.
And the swapped mainboard has CID from 404 (europe), the original was 707 (indonesia).
Okay, back to error something.
WMDC won't recognize the phone unless it's a working WM6.5 device, or a working WP7 device with WP7 SDK + Zune installed on your PC.
Just put the phone into bootloader screen (3 color screen), then connect it to a clean PC.
Does the "Serial" changed to "USB"..?
If it does, reflash HSPL 2.08 using HSPL4 package.
Then flash Radio ROM only, 2.15.50.14 is a good one.
Again, an EU HD2 can use either EU's Radio ROM or T-Mobile's Radio ROM.
But a T-Mobile HD2 can only use a T-Mobile's ROM..!
If the "Serial" doesn't change to "USB" but on your PC makes sound like something is plugged in, open device manager and look for an unknown device (no drivers loaded).
Expand it, what does it says?
To be honest: I am not 100% sure that it is an European (Dutch) phone. What I saw when I opened the phone's back was that the warranty-seals on the screws were molested. I don't think he got the motherboard replaced: way to expensive in relation to a new phone...
The bootloader screen gives now the following text:
RUUNBH
PB81100 HX-BC
SPL-2.08.HSPL 8G XE
0X05
CotullaHSPL 0x40
Upgrade ROM error
Please try again
When I connected it to a clean pc, the phone booted and gave another upgrade-error, only this time on a black screen (I got the uSD out the phone).
After booting the phone and connecting to a pc the "serial" does not change to "usb"...
When I tried to install WMDC I get the error "Installationpackage not supported by processor". Seems like bullcrap, but there it ends. No yellow exclamation marks in Device Manager...
I have yet not tried to flash a T-Mobile ROM to the phone. I have tried all the NLD ROM's: 1.66.404 ; 1.48.404 ; 1.66.404 ; 3.14.404 ; 1.66.404 ; 1.43.404
I have yet not tried the other ROMs I downloaded, but I will tomorrow. To start 161 does not work.
Also: I cannot shutdown when in bootloader or MAGDLr, is that correct?
What colour are your call & end key buttons !
if white you have standard EU type model. T-Mobile EU models are same as any EU model & can flash any ROM/Radio
If green & red you have a T-Mobile USA model (TMOUS) & need correct ROM (found in HD2 Wiki)
T-Mobile USA model needs care as if flash wrong radio version you can brick it.
Flashing via SD card should be last choice as first stage of a SD card flash is install of the SPL to standard SPL from the nbh which means you have no CID bypass as HSPL gone.
ideally you need a Windows 7 32bit machine with a known working WMDC setup & try flashing a suitable rom once decided on EU or TMOUS device.
As you have HSPL on your HD2 already it will bypass CID if flash via PC so you can flash any CID code rom.
Try connecting device to PC (with known good WMDC) and use reset button on HD2 to boot to bootloader & see if get any luck in running ROM installer from PC.
If lucky the USB flash issue is PC & drivers rather than hardware on HD2.
I would suspect you have nand issues on HD2 or perhaps worse, if nand sometimes you can get it back if persistent & get something to flash completely.
Thanks MisterB for adds up.
So am I, suspected a nand issue.
The reason I want him to revert back to original SPL & Radio is to make sure that it's a nand related problems, not radio hardware problems.
If he managed to find the correct CID for his phone, he could easily reverts back in case somethings wrong in the future after playing with custom ROMs.
This also happens to my friend's phone a couple months ago.
But in her case, the bad blocks are definitely located where magldr resides, and many more on data partition.
She can flash shipped ROMs completely, but it refuses to boot.
Can't flash a WP7 ROM because magldr freezes when it's loading, can't even bring the menu screen.
She can run a native sd android build for a couple weeks, but then it acting strange again.
Then finally she just gave up and bought another phone.
@andrejazzz:
You can't shutdown on bootloader (3 color) screen.
Remove the battery is the only way to shutdown, or press the reset button to restart.
But you can shutdown/restart or anything else on magldr menu screen.
Press & hold power key right when magldr loads up (before it's start to "go go go").
In addition, you can download WMDC x86 version here, and x64 version here..
He may indeed need try SD flash but I would exhaust all options of USB cable flash via PC first as retaining HSPL will be useful to start with as any generic HTC ROM could be used for the USB cable flash.
If that is not possible then flashing via SD is only viable option & indeed many times only way get over bad boot/nand issues but with all the CID versions for HTC regions & operator branded regions you have a hard job knowing the right one, you could even try the right ROM & as it does not flash overlook it for further testing.
I see he has tried SD flashing but still has HSPL so either SD card is not best suited for nbh flashing or nand/hardware that bad even first stage of flash is not possible.
If I was testing this device & trying recovery I would probably try freezer test to cool device prior flashing & make good effort on USB flash before going on to SD card.
Most well used Android HD2s these days have nand or bga issues to some degree as android works the hardware so much harder than WM6.5.
You really need be sure PC & driver are known good for flashing & if going to SD flashing that SD card is suitable or you will waste a lot of time & effort.
Loads of links & tips for all the software & some threads are in the HD2 Wiki
I apologize for replying so late, but I have had no time: I had a few tests at school
@Mister B: I have a black HD2 with white icons, so I have a european model.
I have installed installed the X86 on a clean 32-bit system, but it does not recognize the phone. I have reinstalled the WMDC on my W7 64-bit system, but still it does not recognize the hd2. I have no other Windows Phones, so I am not able to verify the WMDC-installations.
When I connect to a pc, the phone boots and shows: "Software update failed! Please try again"
@Shadow_Nexus: Correct, that is exactly what happens. I do not completely understand what you mean with "Press & hold power key right when magldr loads up (before it's start to "go go go")", could you please explain?
@Mister B: How could I check if the SD-card might be the problem? It is a 16GB Class 4 Kingston SD. I have tried all the NLD-roms and other versions (random countries, not TMOUS). I have tried the freezer trick with a NLD-rom on a mSD, but it did not work.
Thanks for all your help!
Best using a 2gb or 4gb (8gb max) card for nbh flashing & do a proper fat32 format with something like hp format tool before using it.

Again, thank you very much for your reply. But: do you have any clue what ROM's I should try? I am asking this, because I have already tried all the NLD ROM's I found on the site @Shadow_Nexus gave in post #4, but every one of them returns the same error. Should I switch to another country and try, for example, all German ROM's?
I got my hands on another HD2 and when I connect that one to my pc it show up, named "HTC Sync". The bricked one still does not respond:/ Should I retry all the non-TMO roms I can find?
Edit: My brother "helped" me out and sold the phone...
I tried to downgrade my htc hd2 to windows 6.5 using sdcard method(leoimg) after sometime it says UPdate failed ,, when i turned on my phone it didnt shows the HTC logo instead of that it says "Software update failed please try again "..HELP ME PLEASE ??
That is because your phone is a branded model & will only load the original country/vendor ROM as they are CID code locked hence your error. When flash via SD you remove any HSPL as first stage of flash hence CID issue of SD flash option ...
Your best option is flashing via usb cable to a pc/notebook with Activesync or the Vista/W7 WMDC6-1 software. First flash HSPL using HSPL4 (HSPL bypasses CID lock) tool then an appropriate ROM.
Go & read through the HD2 wiki as has all the links for ROMs & software tools for flashing plus tips on use.
Do note if you have a USA HD2 T-Mobile (TMOUS) model to be extra careful as can be bricked by wrong radio flashing so do read the wiki FULLY in advance ....
