Error in downgrade from 1.66 to 1.48

Dear All,
Excuse me I'm a bit newbie
I decided to add the miri custom ROM. I'm on official 1.66 rom WWE with radio 2.06. I read in this forum that I have to downgrade to 1.48 in order ro be able to SPL. I downloaded the 1.48 from the thread of Leo official roms in this forum. The process stopped at 1% telling me "Invalid vendor". then I restarted my device but the GSM network is not working.
Please help how could I go back to 1.48 to SPL my device.
Thanks

Maybe you are confused a little: The ROM version is 1.66, but please check the SPL version, and you will know if you need to downgrade.
To check your SPL version:
Turn off your device, push and hold the volume down button and briefly the power on button, this will launch your HD2 into boot loader mode.

downgrade from SPL 1.66 to 1.48
Hi All
I have loaded a cooked rom to my HD more than a year ago.
Could somone please point me in the right direction plz
My bootloader tell me I have I have SPL-1.66.000 XE
How do I downgrade??
Thanks for your time

Your HTC is not HSPL. Use HSPL2 to downgrade your SPL. Chose version which is ending with HSPL 1.42.HSPL. It was something like this.

using the newest hspl3, you don't have to downgrade ROMs. It will scan your device and figure out which hspl you need.

not quite,,, hspl3 will only install 2.08.hspl
hspl2 is the one that contains all the various versions and scans your phone before offering you a match.
either will work for flashing roms, personally i recommend hspl2 for normal hd2, hspl3 for tmous or Telstra hd2.

ok, but isn't hspl 2.08.hspl compatible for all flashing?
from cotulla:
*Now included only 2.08.0000 and 2.08.HSPL.
Seems all ROMs based on 1.42, 1.66, 1.XX can work with 2.08 SPL without problems.*
*Now one HSPL for different LEO types: UsualLEO, TelstraLEO and 1024LEO*
*Because there no SPLs except 2.08, so no risk to brick 1024LEO with wrong version.
*Telstra LEO supported. Actually Model ID checked by first 4 letters.

yes, you can use any version of x.xx.hspl with any rom. THe main difference between whether to use 2 or 3 is that if you want to return to stock, hspl3 will only allow you to go to 2.08.0000, which isnt stock for most users, meaning they have to then switch to using HSPL2 to downgrade, throwing an extra layer of confusion into teh mix.
hspl3 was really released for telstra users (model ID fails with hspl2 for telstra) and tmous users with 2.10.0000 stock spl.
There is no difference at all between using hspl2 to install 2.08.hspl and using hspl3 to install 2.08.hspl. They are identical.
The part about scanning for which spl you already have, that doesnt happen in hspl3, and indeed by default if you dont change teh dropdown, it installs 2.08.0000 stock, which has confused looaaads of people, whereas with hspl2, if you currently have 1.66.0000 it offers you 1.66.hspl by default, or if you have 1.42.0000 it offers you 1.42.hspl by default.

My SPL is messed! Please help!

I wanted to upgrade from Artemis rom v15 to v22 so I did. Suddenly I have issues with freezing and hard resets. I find out that I need HSPL 1.66.
So I tried installing HSPL2 and it gives me an error, something about invalid id.
I try HSPL and it did something because now I have SPL-2.08.HSPL 8G XE showing up in bootloader.
But I'm told it's not what I need and 1.66 is what I need. I can't seem to uninstall HSPL firstly and I also don't know any other way to get to 1.66!
I've even tried SSPL and it doesn't work

dont worry about it. its fine as it now is with 2.08.hspl
hspl2 wont work on telstra. Use hspl3 (which i assume you did to get 2.08.hspl) and you can now stop worrying. All roms will work fine on 2.08.hspl, the recommendation to match the spl to the rom doesn't really matter.

thanks for the reply and the info. I ended up getting the stock Telstra rom back on via straight SD flash and decided to try SSPL and it flashed ok so far.
After I flashed 2.08 Artemis said "I think you have problem Sir
My suggestion is, first to solve HSPL problem (post to HSPL thread)
or use SSPL (remove HSPL first)...". So I guess that's what I did.
Right now I seem to have 1.42.6666 showing up. Do you know how I can get to 1.66?

If your spl in bootloader ends...
.0000 = stock
.hspl = hspl installed
.6666 = rom was flashed using sspl. This is not permanent, single flash only, you need to use SSPL each time you flash
You can't flash radios with SSPL, so you may have trouble with cooked roms that require a particular radio. (Roms with the 576 RAM unlocked, for example, require you change your radio, which is almost certainly why artemis rom failed)
you cant get to 1.66.hspl directly with a telstra,
(well, you can, using the ''HSPL2 on telstra'' workaround,, , its posted in the rom dev section)
however I can promise you you will be just as well using hspl3, and installing 2.08.hspl

[Q] Serious problems with Magldr and HSPL3

Hi everyone!
Been surfing the web and xda for solutions to this for 5 hours straight and I can't find anything that helps me with my problem. Can't find a thread about it either, so I hope you guys can help me.
So I got my HD2, trying to run Android on it via NAND, but first off I'm not able to use MAGLDR; When the HTC-screen with the progress bar comes up, but just locks up on 0%.
I google it, and look it up here, seems i need to run HardSPL and get a new to get this badboy to work, but when i try running that, i get the error message "Bad spl".
Now where do i go from here? Did i miss something when looking for the info?
If anyone has a solution to my problem, I would be thrilled.
And if you need any info, just post and i'll provide whatever info you need!
Thanks in advance!

I've got the same problem. Already got the original 3.14 WM rom and darkstone froyo superram installed.
Today I wanted to flash to a NAND rom, but had the same problem as you. Could have something to do with HardSPL not flashing the stock 3.03 SPL.
I'm also waiting for help

Hello,
I also ran into the same problems as you guys. It very important that you flash a rom that a HASPL lower then version 3. I notice that 3.14 stock rom comes with version 3.xxx of HASPL what made it impossible to flash to 2.08 HASPL what is also needed for MAGLDR 1.11.
So I flashed a the 1.66 stock rom version from my SD card then there was an older HASPL present on my hd2. So far, so good. Then i flashed to MAGLDR 1.11. But my hd2 won't start up anymore. Just the white HTC screen. The reason was that my radio version wasn't the right one. It has to end on x.50 and not x.51. So I flashed a x.50 version of the radio. Then I flashed MAGLDR and I was on my way again for android nand flash.
Hope this helps ...
Grtz

Check your radio version
I have the same problem like you,
I resolve the problem when I change the radio version to Radio_Leo_2.15.50.14
P.S. When you flash with some old official ROM you also change radio ROM
now everything work

If you have SPL 3.03, you cannot flash HSPL 2.08 directly into it. It will not work.
So if you have a HD2 device with 3.14 HTC HD2 official firmware, you will have SPL 3.03.
You must downgrade your SPL 3.03 to SPL 2.xx or SPL 1.xx before HSPL 2.08 can be installed.
US T-MOBILE HD2 (1024MB ROM)
You need to find 2.10.531.1 or 2.13.531.1 OFFICIAL FIRMWARE from T-MOBILE website.
You cannot use 3.14.531.1, which is the thing that gave the SPL 3.13 in the first place.
You need to extract from the EXE file using 7-ZIP or WinRAR RUU_signed.nbh, and rename RUU_signed.nbh to leoimg.nbh and put it on a FAT32 MicroSD card, then turn off your device, hold volume button, then turn on the device.
PRAY.
HTC HD2 (512MB ROM)
You guys are lucky.
Goto HTC's website, choose the country where your phone is from.
Download 2.xx or 1.xx version of the official ROM
Extract RUU_signed.nbh and rename it to leoimg.nbh, then copy to FAT32 MicroSD Card.
Turn off the device, hold volume button, then turn on the device.
After the SPL is no longer 3.13, use HSPL3_PK and update to HSPL 2.08
Remember to flash your radio to 2.15.50.14.

[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.

[Q] Can't install HSPL with 2.05 SPL version

I can't install my HD2 T-mobile with HSPL3 or HSPL4 version.
It's running windows mobile 6.5 with radio 2.08. SPL 2.05. I can't find any where.
Any one have any Idea please!!!
I've tried to flash with stock rom 6.5 but I can't. It's stop at 0% while flashing for a long time and I must recovery it.
Thanks so much for your attention.
