VBNHOST.com doesn't work and hasn't worked for days.

UPDATE: it worked finally!!! yay! thanks Xmoo excellent work! (albeit the dl site is a bit off centre-- but not too hard.) Just look for xmoos then go in until you get to the 10.1 and right-click save link as... keep retrying vbnhost.com off and on until you manage to get it up.

Specifically:

go to http://vbnhost.com

click xmoo

click Leo

click TMOUS

To the right of RUU_Leo_1_5_TMOUS_2.10.531.1_Radio_..zip find the green down arrow with 289 by it and right-click the arrow and click save-as.

I attempted to flash it from the SD card with SPL installed. No dice. Had to flash HSPL and then flash on top of it.

So far, 2.10.0 is the best solution for a "back to stock" flash like that.
[T-Mobile HD2 Windows Mobile 6.5 Development] Reignzone:
Has anyone managed or found a post where someone pulled the OEM phone canvas from the T-Mobile USA HD2?

I'm trying to figure out how I can get my hands on the original HTC dialer... in .CAB form preferably.

Thanks.
[T-Mobile HD2 Windows Mobile 6.5 Development] lllpulselll:
question...

If i were to use the HSPL2 program to remove HSPL after i flashed the stock .10.1 rom via the auto installer, not by SD card flashing the LEOIMG.NHB would it have the stock rom and stock SPL again? I've flashed the phone and tried a few different roms, honestly I wish I never touched it, the custom roms always have some problem with multiple apps I like to run and they change the few good things about the phone such as the interface of the photos, music etc from the ipod left right, right left scroll to up and down, they all make it so basic and boring looking like an old phone, and i haven't noticed a battery life improvement or a speed improvement, I have managed to make my HD Wobble and VR Hologram not work anymore though.

Edit: Nevermind apparently you need to use the ship rom from SD card to do this according to the HSPL 1024 Program's instructions.
[T-Mobile HD2 Windows Mobile 6.5 Development] the0stranger:
I've read post stating that you need a factory shipped rom flashed from the sd card.

Yeah, it's likely that any custom rom will have some issue, that's just the nature of custom / beta software and systems. You have to decide if trying something new and the latest system is worth the trouble. I do have to say that I've flashed 3 Kumar roms and have had no issue of any kind with them.

Hopefully someone that knows GSM more than I will confirm your back to stock question.
[T-Mobile HD2 Windows Mobile 6.5 Development] Laurentius26:
That's correct, this rom is dumped from a T-Mob USA device and reconstructed to a stock ruu_signed.nbh with included stock SPL.

If you rename the RUU_Signed.nbh to LEOIMG.nbh and flash from storage card (volume down plus power button to bring it in bootloader)

you will restore the original stock SPL as it's included in this rom for warranty issues.

We all need to thank the Netherlanders for all their hard work;)
[T-Mobile HD2 Windows Mobile 6.5 Development] jessepatty:
I just followed these instructions to the "T" and on the bootloader I got an "Upgrade Rom code error, Please try again" right after it began installing the stock ROM. When I bring it into the boot screen it now says "UPDATE ROM CODE ERROR" on the screen then it goes to a gray "loading" screen, but nothing ever happens. it just sits there forever.

I tried both the Up and Down volume buttons together to reload the rom and there is nothing....It comes right back to this gray "loading..." screen.

Here's a youtube video on what it does now. http://www.youtube.com/watch?v=eCD_-EuI1_Q

Help please! I just bought this phone 2 weeks ago. :eek:

As a note, I wrote down the original ROM specs prior to doing anything with the phone and the stock ROM I downloaded to reinstall is the same exact one which came on it new.

Rom Ver: 2.10.531.1 82076 WWE

OS Ver: 5.2.21889

ROM Date: 2/22/10

Radio: 2/08.50.08_2

Protocol: 15.34.50.07V

Commented on youtube!
[T-Mobile HD2 Windows Mobile 6.5 Development] Laurentius26:
Hi,

So you did rename the RUU_Signed.nbh to LEOIMG.nbh and copied it to your sd card?

You can also use de Custom ruu included, put your device in bootloader and flash using a usb connection.

Offcourse you first need to remove the RUU from your SD in order to do that otherwise you get the whitescreen again. ;)

Looking at the Youtube there is nothing bricked as I see the bootloader in your video.

I'm asuming that you have a T-Mob USA HD2 as this stock rom has

SPL included.
[T-Mobile HD2 Windows Mobile 6.5 Development] Bigshow281:
I too have tried to restore my HD2 back to stock using the RUU_Leo_1_5_TMOUS_2.10.531.1_Radio_Signed_15.34.50.07U_2.08.50.08_2_Ship.zip file downloaded from this thread. I followed all the instructions precisely. I renamed the ruu_signed.nbh to LEOIMG.nbh and copied it to a freshly formatted 8GB micro sd card. With the phone off, I inserted the card, the battery, and then turned it on with the vol down pressed. I then get the rainbow screen that says:

PB81120 SS-B3

SPL-2.08.HSPL 8G XE

0x05

CotullaHSPL 0x40

Then in the white square I see serial. Thats it. The phone does nothing else from this screen. No all-white screen to install the new image like I've seen in countless youtube videos. WTF am I doing wrong? I have a 1024LEO TMOUS btw. Can't I just run the customruu.exe from that zip file with the phone activesynched?
[T-Mobile HD2 Windows Mobile 6.5 Development] xmoo:
The SPL in 2.10.1 isn't working correctly. So just flash 2.10.0 trough sd-card!
[T-Mobile HD2 Windows Mobile 6.5 Development] Bigshow281:
Alright, I may give that one a go later. I'm still debating whether or not to return this phone. Coming from a T-Mobile MyTouch, the Windows Mobile platform isn't blowing my skirt up at all and there are some bugs in the HTC Sense portion such as my music stopping randomly on its own, so now I have to use WMP but I can't seem to create a playlist using it, among other annoyances I have found. Since there are really no other options for me at T-Mobile other than downgrading back to what I had previously, I guess I'll just have to learn how to live with winmo...

Cant you just flash the shipped ROM .1 thru PC and then once its flashed, run the HSPL2 program to uninstall HSPL2 and return it to the stock SPL?
[T-Mobile HD2 Windows Mobile 6.5 Development] xmoo:
Think so, just try. If not working flash .0 with sd card.
[T-Mobile HD2 Windows Mobile 6.5 Development] lrosado:
Just tried it and it worked, back to stock .1 ROM and Stock SPL. Thanks again xmoo!
[T-Mobile HD2 Windows Mobile 6.5 Development] Phenomenon:
Wait I just tried to return to stock SPL and I got an error. Currently Im reinstalling the .1 stock rom (God I hope it'll be ok), but when I did the uninstall that it required through a micro SD it wouldn't even boot up to normal. It would say software failure or something like that. What .nbh file did you use?

**** the progress bar for reflashing isn't moving. Hope I didn't screw myself over with this.
[T-Mobile HD2 Windows Mobile 6.5 Development] xmoo:
Try flashing .0 and then .1
[T-Mobile HD2 Windows Mobile 6.5 Development] Phenomenon:
Ah, got it. Thanks. Something weird about the Rom that it shipped with. Your is a little different. I remember when I got it Sense UI had tabs for the eReader and a Facebook tab.

[T-Mobile HD2 Windows Mobile 6.5 Development] Snarksneeze:
Nah, they are still putting out builds. They just aren't tested enough for a manufacturer or phone company to actually trust yet.

So, we get those newer builds and cook 'em into our own ROMs and share them with others here at XDA. It's bleeding-edge and terribly dangerous (how many cooks have never bricked their own device trying to make a ROM? LOL!) but then that's okay, 'cause we're willing to take that risk :D

[T-Mobile HD2 Windows Mobile 6.5 Development] skr_xd:
IT IS A TEST ROM.

It won't harm if you are NOT flashing by SD Card and HAVE Hard SPL installed. But, if you don't want to experiment, don't flash it.
[T-Mobile HD2 Windows Mobile 6.5 Development] invalid_character:
So basically, I could use HSPL1024 to reflash to SPL if I wanted to and be fine. Particularly on when the shipped version comes out?

Yup, I am good. I have a spare TMOUS HD2 with spl installed etc.... as I use it to try out new ROMS.

2.11

I flashed my stock TMobile hd2 with HSPL and then Kumar's rom last week. The ROM is great, but the 2.08 radio was not. At my job the radio reception changed about every 10 to 20 seconds from 1 bar edge, to 2 bars edge, to no bars, to no signal found at all, to having 1 bar 3g, and it would just cycle and cycle in a seemingly random pattern. I could only send a text about 50% of the time.

The good news: with 2.11, I seem to get 3g 1 or 2 bars. No edge, and while it does change from 1 to 2 bars, its every few minutes, not every few seconds. I have been texting my wife with no problems this morning.

[T-Mobile HD2 Windows Mobile 6.5 Development] Zoskalon:
Everyone, I would recommend to definitely wait for the final official release. And even then, I would recommend flashing a nice clean cooked 2.11 rom. I am using the "test only" 2.11 rom and my internet connection is MUCH better, though still jumps around in my basement (with AT&T, I had solid 3G in my basement). However, the other aspects of the rom are HORRIBLE. The screen sensitivity is ridiculously low, you have to really push down in order to increase the surface area of skin touching the screen. And scrolling is not very fluid.
[T-Mobile HD2 Windows Mobile 6.5 Development] justwonder:
This rom very good if you can dump and cook yourself, just replace touch.dll and touchgl.dll from 2.10 rom. i have the best battery life with this rom, and it faster than 2.10

+1 on this. I have been using it all weekend and I gotta say it is choppy as hell and it actually crashed a couple of times already.

[T-Mobile HD2 Windows Mobile 6.5 Development] egzthunder1:
Solution for 2.09 SPL found

Maybe some of you already know this, but I will post it to help people that freak out (much like I just did)

If you flashed 2.11 Test, you will find yourself with a brand new 2.09.0000 SPL, which you will not be able to patch using HSPL2 tool. Moreover, you will not be able to flash 2.10.531.1 from this thread since it comes with a Custom RUU. Here is what I did to get mine back to normal

*Flash from the computer to 2.10.531.0 with the link found in the first post of this thread. This will put 2.08.0000 back in there (removing the 2.09)

*Now that you are back on 2.08, use HSPL2 to get 2.08.HSPL

*Now, flash 2.10.531.1...

And you are all done :)
[T-Mobile HD2 Windows Mobile 6.5 Development] cu2cool:

[T-Mobile HD2 Windows Mobile 6.5 Development] onslaught86:
Funnily enough, I find myself going back to 2.10.531.1 after using a few custom ROMs. For everything the cooked ROMs fixed, they threw in an app or a tweak that brought back the standard WinMo "It sorta works if you ignore this and don't click on that" problems. This is the first time I've ever liked a stock ROM. Bloatware aside, it's smooth, fast, responsive, and has never locked up on me.

I'll miss the 6.5.3 start menu on the bottom, though. Reaching allll the way up the HD2's screen to tap the start button annoys me, I always forget about the hard start key. C'mon, official 6.5.3 update.

agree, let's help them not brick thier phones.

Radio is the firmware/hardware responsible for GSM/WIFI/Bluetooth etc in the phone. it has nothing to do with the fm radio function in the device.

When we talk about different radios we talk about signal quality of both mobile towers or cells and battery life with that radio version. this is because different radios work better for different areas and/or providers and provide differing battery life.
