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] Do i have the right SPL?

Hi everyone,in advance i would like to tank everyone that take the time to read this threat!!!here is my question...i had a Nand Android Rom on my Hd2 and unfutunaly the phone stop getting signal(phone's problem)and i have to send it back to Tmobile.i read all the theats i was able to,and to what i understood i had to flash a stock windows 6.5 rom,i also read on a theat that any SPL ending on .0000 would valid my warranty!!!every thing its done to the phone...i now have a stock rom and my SPL is 2.08.0000. My question is...is this the right SPL for US T-moblile users?if not,can anyone link me to where i can find it?ones again guys!!!thanks a lot for the time!!!

That all depends on the build, it could also be 2.10.0000 or 3.03.0000. If you flash the original rom from the sd card you will get the correct spl version back as that is also installed.

If u have a SPLhigherthan 3.03, is that bad? Or just different? Cause when i got my phone back from repair i could play andriod on SPL 3.03 (or higher) and i had to downgrade my HD2

Not necessarily bad, it's just that the tools to "hack" the spl to allow you to install other roms does not work with spl 3.03.0000. The way around this is to downgrade the rom and with it the spl version to 2.10.0000 so that you can run HSPL.

[Q] Verifying requirements...thanks.

Just need to make sure I understood everything correctly, it's been a while since I flashed HSPL and MGLDR. My replacement phone just arrived.
I noticed that I have SPL 2.10 in new HD2
Is it safe for me to flash HSPL4 2.08 from 2.10? I'm an Android NAND user.
Then I follow up with MGLDR 1.13...
Next is Rom of choice...
I'm primarily checking for the safe flash from 2.10 to 2.08. Cuz 2.08 is required for everything custom HD2...right?
When I had to restore the default SPL in defective HD2 I was told to flash 2.08...how come this new HD2 has 2.10? I don't want to void warranty...so I have to make sure the correct SPL is in old HD2...right?
Thanks!

[Q] Remove HSPL 3

Hello everyone
I know this is a question that has been asked 100 times before, but a post from mskip got me worried.
Here's my problem:
- I want to install a Gingerbread ROM on my HD2. I have understood everything about how to do that, thanks to XDA.
- My HD2 is currently running a Winmo 6.5 3.14 stock ROM from HTC's website.
- To install it, I had to install SPL3 on my phone. So on bootloader, my phone now shows SPL-3.03.HSPL (Cotulla HSPL btw, thanks Cotulla )
- And to install the Android ROM, I know I have to downgrade to SPL-anything between 1 and 2.
- I know you can do that by installing a stock ROM, but I read somewhere in a post by mskip that you CANNOT suppress HSPL3 by downgrading the ROM.
Anyway, in short, my question is:
Can I suppress HSPL3 and eventually manage to start the install of an Android ROM?
I'm not a complete noob, but not an expert either and I don't want to brick my phone or anything.
Thank you very much in advance

I don't understand what you mean by "suppress" it but basically all you need to do is to get 2.08.HSPL on your phone. How you do that is boot to 3.03 (volume down and power) and open HSPL3 on your PC. Then after it finds your phone etc. on the phone just choose 2.08.HSPL from the menu and flash that. Then after that installs you should be able to flash your radio and MAGLDR etc.

Skellyyy is completely right you need to run the HSPL again on your HD2 and select HSPL version 2.08 HSPL because MAGLDR only supports 2.08 HSPL right now. You will hsve to flash MAGLDR in order to flash a Andriod ROM.

Thank you guys for the quick answers.
But the point is that the ROM I currently have (3.14) only runs with SPL3.
So if I downgrade to HSPL2.08, isn't there a risk that my phone is not going to be able to do anything after that, let alone installing Android?
See, that is a quote from the post I'm using to install Android. It says:
"A: Install HSPL3
Prerequisites
* Windows Mobile Device Center installed on Windows Vista / Windows 7 or
* ActiveSync installed on Windows XP
* You must have any SPL version from this list on your device:
o SPL 1.42.0000
o SPL 1.62.0000
o SPL 1.66.0000
o SPL 2.07.0000
o SPL 2.08.0000
o SPL 2.10.0000
(To check your SPL version, hold the Volume Down button and do a reset)
You should have this SPL version unless you are using the latest 3.14 ROM with SPL 3.03.0000. No worry, just downgrade your Windows Mobile ROM from v3.14 to v1.66 will do. Download HTC HD2 v1.66 ROM. Then downgrade your phone from SPL 3.03.0000 to SPL 1.42.000."
So it says here, downgrade to v1.66 ROM, and then downgrade from SPL3 to SPL1.42. That is not very clear to me. Isn't that supposed to be the same thing?
If downgrading to ROM 1.66 downgrades SPL to 1.42, then why should I AFTERWARDS downgrade from SPL3 to SPL1.42? Isn't that going to be already done?
And more importantly, you guys say I should simply run HSPL and choose an appropriate version, which is yet another method than what is explained above...
Oh boy I'm confused...

No need to worry my friend I am currently running a 3.14 ROM as you can see by my sig. I also have HSPL 2.08 on my HD2 just incase I decide I want to run Andriod or flash a custom ROM. I can tell you my HD2 is working just fine.
No those prerequsites are just the showing you the SPL version that you habe to have to flash HSPL 3. You only have to have ond of those versions but it has to be a version included in the list or you can not flash HSPL 3. If you do not have one of these versiond then the flashing to 1.66 then to HSPL 3 is just MSkip telling you how to get a SPL version needed to flash HSPL 3. But this is not needed now as there is a HSPL 4 version now that allows you to flash 2.08 HSPL when you have SPL 3.08.0000 or SPL 3.10.0000 with out having to downgrade your ROM.

So that basically means I should get HSPL4, run it and choose HSPL2.08 for example, and then I will be able to follow all steps to install and Android ROM?
Correct?

You have a tmous,,, you can't run 3.14 roms on a reg hd2 with any spl except 3.03.0000 or 3.03.Hspl.you get very unstable phone that thinks it has the 576meg ram unlocked but only really has 200 or so,with only 50 or so free for user apps. Unuseable.
OP correct, into bootloader, Hspl 4, 2.08.Hspl then back into bootloader and flash magldr from there.

Samsamuel I do understand what you are telling me here and I was a little concerned about this when I first flashed the HSPL 2.08 to my HD2. But to be honest I have noticed no real change in my HD2's performance compared to before. Also to be fair though I only have 5 nonpreinstalled apps on my HD2 as I found early on with my HD2 that a lot of apps can effect the performance of the HD2. I also never have more than two apps running at the same time as a rule too.
At the OP yes download and run HSPL 4 and choice 2.08 HSPL and you will be good.

because you have a tmous,,,,,, tmous 3.14 rom comes with spl 2.10.0000 and works with 2.08.xxxx, (or it may come with spl 3.03.0000, im not sure, but it doesnt require it, and your phone is proof of that) however the regular 3.14 roms come with and will not work without 3.03.xxxx.

Oh I get what you are saying now the TMOUS can do this but the EU can not. I was not aware of this. Sorry it took a minute for me to understand, I have been sick for like two weeks so my head is a kittle foggy because of it lol.

heh, it doesnt get mentioned often in relation to tmous.
tmous users never get the unstable system/bad ram error when they flash 3.14, regardless of the spl, so they never need to notice what the spl is before / after, so dont notice it didnt get updated.
Im sick too, its the time of year for it. Not that anyone would notice teh difference, i am still sat hunched over the keyboard, swearing under my breath occasionally at anyone who gets close,,,,,

Sam, it wouldn't really matter though would it? As he plans on flashing MAGLDR straight away so there wouldn't even be WinMo on the phone to make it unstable?

Oh no course not, all that stuff is fine.

Thank you very much guys, this is all very clear for me now.
I now know that HSPL4 -> 2.08 -> then droid flash is doable for me
Good night/day to you all.
