Finally found how to downgrade SPL 1.24 to 1.19.Hard - Dash 3G, Snap ROM Development

Like several i flashed the official 6.5 rom from HTC and my spl moved from 1.19 to 1.24.
You'll find the way i proceed for my SNAP :
1 / Flash the Evo 1.60 rom (may work with the version 2) using auto1.19.bat
The rom was flashed but my spl stayed 1.24
2/ Flash the original SPL 1.19 using Jocky's package
copy maple-original-spl-1.19.nbh file from Original SPL folder to main folder..
rename maple-original-spl-1.19.nbh to hardspl-maple-1.19.nbh
3/ Flash the Hard SPL 1.19 using Jocky's package
Now i can do what i want with my snap

It's work also using direct HardSPL only!!!

Nothings work for me. I have got original HTC Snap from Telstra. I never HardSPL it before. My SPL says 1.24. I have tried all methods stated above, but no luck. The update stuck at 0%.

how can i install an old ROM ?

i am using currently AKU3.3 jester b1 and want to install JAMin's old ROM but the flasher is giving an error and asking to use a newer version of nbf file.
is there a way to install an old ROM to my device ?
try to cook a rom with the nk.nbf from your "old rom" using this tutorial
http://forum.xda-developers.com/showthread.php?t=271043
this rom will install on spl 2.20 also if it's for spl 2.15
when you tried installing your "old rom" it stops at 95% right?
i had the same problem with my german rom and after using this tutorial i can now use the spl 2.15 rom with my spl 2.20 prophet
good luck
this can brick my phone as it is vey risky.
is there a simple way just to flash my phone to an old ROM i mean from 2.20.7.34 to 2.13.9.23 ?
If you had read the post of risidero carefully you would know that it could NOT brick your phone
it modifies your rom so it doesnt contain any IPL nor SPL data. they are staying untouched
the only risk is a non booting ROM which you can simply flash againt when going to bootloader (hold camera button while soft reset)
risidoro said:
By following this tutorial, you're removing both the bootloaders (IPL and SPL) from a rom of your choice. This means that, if you don't make errors while 'cooking' the rom, you cannot completely destroy (brick) your phone. Sure, you could end up with a non-booting rom but, as long as you can get to the three colors screen (the bootloader screen) you'll always be able to install a different (or your previous) working rom.
On the other hand, messing with IPL and SPL (i.e. installing a rom containing IPL and SPL in a CID locked device) is EXTREMELY DANGEROUS and MUST be avoided in most cases!!!
Installing a 2.xx rom without messing with your phone's IPL and SPL is exactly what this tutorial tries to explain.

Radio downgrade

Hi,
Is it true that once you upgrade a radio version you can't go down to a lower version. I've successfully managed to install version 1.34.405.1_4.1.13.54_03.10.90 from Radio 4.1.13.54_03.10.90 (don't ask why) but my phone still says I have Radio 4.1.13.54_03.10.90.
Thanks
No that is not true. That is the exact same radio version you posted. Some ROM's do not flash a radio. The best bet is to flash a stand alone.
Once you are finished flashing your ROM and happy with your device. Patch SPL using the regular SPL method and then run FLASH from within the SPL folder, this will flash a patched SPL to your device and act as a Soft SPL. From here you can flash any radio and number of times to test the best one.
Hope this helps you out.
I also tried many radio versions before setlling down. Ofcourse you can downgrade it as h4waii said
Thanks for the help.
Is the method given by jockyw2001 Soft SPL because if so that's what I've been using.
Btw, what does SPL stand for?
Thanks
It should be in the Wiki, the uSPL is by jockyw2001 and it is loading a patched SPL from RAM. Flashing the uSPL over the ROM SPL will turn it into a "soft SPL".
SPL stands for Secondary Program Loader

Questions about IPL/SPL and hardspl

Hi,
My old Dopod 818 originally showed the following when booting:
IPL 1.00
SPL 2.15.0000
GSM 02.19.21
OS 2.15.13.27
I used "Prophet Upgrade 2.6 - bikertibi" to upgrade it to WM6.1. I selected HardSPL in that program, and flashed it. This worked fine (scary moment
However, when I boot it now, it STILL shows the exact same IPL, SPL and GSM versions. Only the OS version has changed.
My question: is this normal? I thought the hardspl would change the IPL or SPL versions on the phone?
Is it possible or usefull to upgrade IPL/SPL also?
Second question: if I want to re-flash it again to another 6.5 ROM, can I just use this utility again, without hardspl selected, and without first downgrading back to WM5?
Thanks a lot...
Yup, it's normal because cooked roms don't include ipl/spl (prophet has 2 version : G3 and G4) and radio ... you wouldn't want to brick your device if flashing wrong ipl/spl would you?
However, it is recommended to install HardSPL so that if anything happen during flashing, you can recover the device via entering bootloader mode and only select your device version (G3 or G4) without selecting HardSPL.
ps : your device is G3 because it ends with 0000 .. read the wiki. TQ
Thanks for your reply. So I guess there is no need for me to upgrade IPL, SPL or radio.
How do I know if hardspl is installed?
And if I want to re-flash it again to another 6.5 ROM, can I just use this utility again, without hardspl selected, and without first downgrading back to WM5?
PS. I know my device is a G3, since I already flashed it (see above)
Thanks again.
HardSPL have number like this 2.G3.4PDA (for G3) or 2.G4.4PDA (for G4)... if you haven't HardSPL your device, you need to have HardSPL ticked before flashing. And if anything happen during flashing, your hope is to flash NVID flash.
If your device already HardSPL, you can just redo the flashing. No need to flash NVID unless HardSPL gets overwritten by stock ROM.
Hope this helps.
ps : lucky you .. G3 has more storage memory than G4 ... mine is G4 ...
So if hardspl is present, I should see something like SPL = 2.G3.4PDA at the bootscreen? This is not the case, I still see SPL 2.15.0000 like it did before the flashing. So I guess I don't have hardspl? But how can that be? I click on hardspl in the upgrade tool, and it didn't give an error message... Or do I need to add extra SPL files for this?
It's still unclear to me if I have hardspl installed or not :-( If it's "no", how could I have installed a cooked rom??? If it's "yes", how come I still see SPL 2.15.0000 at the boot screen?
Any help is appreciated!
From what I understand, bikertibi upgrade tools suppose to hardSPL the device but sometimes it seems to just load SoftSPL to the device so that it would temporarily make the device SuperCID? (will experimenting on this) Only SuperCID device can accept any rom. That's why if anything happen during the flashing, your device can only be recovered either by flashing specific CID (t-mobile/cingular/etc) rom or NVID (no specific vendor) rom if it doesn't HardSPLed. It will either reject the flashing process and the device will stuck in bootloader mode.
Since your device still shows SPL 2.15.0000 the answer is no, your device is not HardSPL. Cooked rom was flash successfully because SoftSPL in bikertibi 'tricked' the RUU to be SuperCID temporarily during flashing so it can finish writing a custom rom.
HardSPL for G3 can be download here : http://forum.xda-developers.com/showthread.php?t=353547
To flash a HardSPL, the device needs activesync/wmdc connection to load a special SoftSPL into the device before it can overwrite the stock SPL.
ps : I recommend you learn how to create SDcard dump if you don't want to HardSPL your device. This is because other than flashing stock ROM/NVID, your device can still be recovered using SDcard backup (it will overwrite everything including ipl/spl/os)
EDIT : Flashed my device to IPL/SPL 2.20.0001. bikertibi HardSPL ticked during flashing only send SoftSPL. Flashing was successful. Still need to flash HardSPL 2.G4.4PDA again after phone boots up normally to make it 'immune' from bricking
aze2learn,
Thank you very much for your help.
Indeed, after using the Prophet upgrade tools and activating "hardspl", hardspl was still not on the phone (so it must have used softspl). I installed it manually via the link you provided, and the SPL value changed! After that, I upgraded it to bikertibi's rom.
Very happy with the result.
Thanks again, I will also try the SDcard dump later.

SPL 1.24

this was obtained from Mobilicity ROM. Hope someone can make Hard SPL out of this
After download, I want to do?thank YOU
+1 - I couldn't flash 1.17 or 1.19 HardSPL no matter what. In fact, I bricked my device trying to flash 3VO, with no shipped ROM to flash back to.

HSPL Question

Hi,
I am thinking about installing :
- Leo_Radio_15.40.50.07U_2.12.50.02_2
- Mdeejay_eVo_Sense_v._1.6_REVOlution_Final
That i downloaded from a friend of mine.
But when i just got a quick question.
At Hspl it says :
1) To install this HSPL there must be any SPL version from this list on your device:
SPL 1.42.0000
SPL 1.62.0000
SPL 1.66.0000
SPL 2.07.0000
SPL 2.08.0000
SPL 2.10.0000
Otherwise the installation will fail!
You can select which SPL version to install in "Choose SPL" screen. To check your SPL version, hold the Volume Down button and do a reset.
It is possible to downgrade to this SPL, by just flashing to an Official ROM with this SPL version.
But i got version :
Rom version : 1.66.404.1 (76641) NLD
So can i install it then or not?
I have never updated the phone .(just got it about 2 months)
Please help me.
Ty,
Thomas
