I want kno the same thing.
Is there a tool to downgrade just the SPL/IPL alone without changing anything else or still downgrading the OS ROM is the only way?

there are several tools that will end up by giving you what you want but you must build the RUU yourself.

HOW:
Get an RUU with the IPL/SPL version you want (be carefull with the G3/G4 difference!!!!)
Extract the nk.nbf from the updater and then extract the chunks (you can use my tool or typho5.exe)
Get nb2nbf_tornado.exe and make your own nk.nbf with IPL/SPL only
Pack it again inside an RUU updater and use it to flashThat's it :D

cheers

PS:
Use the search to feature to learn about "nb2nbf_tornado.exe" ;)

Or you could flash the lowest T-mobile rom you can find, it should put you back to 1.08 or something like that!!! When i have to downgrade i always get these!!! Then you just upgrade your OS again to what you want and there you go!

I have a HTC Wizard G3. Can I use Button Wizard ROM's SPL/IPL?
I used nb2nbf_wizard.exe to make what's in the attached picture. Does it look correct?

Also, I have nb2nbf_tornado.exe & nb2nbf_wizard.exe...are they the same thing. There both v2.02.

Great!! I deff will.

When using your Wizard Service Tool, if i do Read ROM-->SPL...will this also read the IPL as well??
I want to know so I can just do a Write ROM---->SPL to restore both after I downgrade to SPL/IPL 1.xx.

nope. IPL is not readable via RAPI/TRUEFFS tools like my tool, only via boot loader and SD card i guess...

Oh ok. Then how would i make a backup of my SPL/IPL. I looked at aWizard, but it doesn't support it.

no it doesn't. aWizard is based on same apps as my tool; in fact aWizard is where i got my inspiration from (thanks ahlok_hk :D)

as i told before, only using mtty and boot loader commands to make a full backup to the SD card, but for that the phone must be CID unlocked :mad:

But IPL/SPL are generic so you just grab a RUU updater with same IPL/SPL as yours and you'll have your backup ;)

I extracted these from a OEM Cingular ROM. What are the differences between both sets of SPL/IPL's??
When restoring my SPL/IPL, which set should i use?

[mestrini]

Okay, this is where you got to be careful since a pair is for G3 (IPL_1) and the other is for G4 (IPL_2). You don't see it in 1.x ROMs since there were no G4 devices then ;)

Wow, thanks for letting me know. I'll make sure to use the IPL_1 for my restore.
