What exactly is IPL and SPL

Searching the forum for these words gives too many replies. So I would appreciate it if someone would explain what IPL and SPL exactly are. On my Prophet IPL = 2.10.001 and SPL = 2.15.001. Should they not be the same, and if yes, how can I upgrade IPL only (whatever it is).
Who will shed some light on this?

IPL = Initial Program Loader, this is the bootloader
SPL = System Programming Language (I Think), Not sure exactly what this does. Its has something to do with the Chip, in the Prophets case.
G3 chip ends in .000 or G4 ends in .001.
I have IPL 1.0 but my SPL is 2.15.000 (i.e I have a G3 chip)
I also know higher SPL's are a pain to unlock, you have to try and downgrade
Hope this helps, it's only what I can gather.
Regards
Austin

how does one downgrade or upgrade?

Guess, that SPL is something like hardware abstraction layer software, platform &chip dependent.

Austin, you are right, just one thing. The Chip G3 ends in 000 and the G4, ends in 001.

What's the risk of flashing a Prophet G4 with a G3 ROM, or a Prophet G3 with a G4 ROM?

Your service centre may be kind enough to repair the phone under warranty if you manage to do this mistake. The phone will not start again if you flash it with the wrong IPL/SPL and without specialised equipment a main board replacement is the only solution to this.
(I did this myself and it took the service centre three weeks to fix it. I guess they struggled with their JTAG cables and then gave up and just replaced the board instead.)

The most of service centers does nothing but changing boards, display and other parts, and do some software loads via USB. Most of the services has no even JTAG equipment nor documentation on how to load the flash via JTAG.

What could be the differences between IPL/SPL versions?
Like I have IPL ánd SPL: 2.10.0001
While most people here on the board seem to have 2.15.0001
Also saw some ROM upgrades (the pdamobiz one for instance) which says it's for 2.15.0001. Although on their english forum it says 2.xx.0001, but not in the file
And while I'm at it (another sneak question ), I guess the pdamobiz rom (aku 2.3) upgrades the device to os: 2.15.13.27 right?

IPL = Initial Program Loader
SPL = Second Program Loader (System Programing Language does not make any sense)
IPL Trigger SPL and then SPL activate the OS
They do the Hardware check-around and hang up if something wrong happens.

can someone help me to find IPL 2.15 for G3 prophet

I flashed my Dopod 818 Pro with lvsw's AKU2.3 & AKU2.3.1 and my SPL was changed to 2.20.0001 while IPL was kept 2.15.0001. I wanted to install the official Dopod AKU2.0 ROM back but it failed. I used ROMUpdateUtility.exe and it failed since initialization. If I used ROMUpdateUtility_No_VID.exe it failed at 95% which I believe the official .nbf file has some conflicts with SPL.
And I can't downgrade SPL back to 2.15.0001.
I saw some thread saying that there's no mean to downgrade G4 chip.
Does it mean I have to use AKU2.3 from now on?

No. Search this forum. There is a procedure for updating a G4 phone without touching the IPL/SPL areas. Be careful though! A mistake when attempting to upgrade your PDA may result in it being downgraded to a paper weight!

I have A Wing and I Dont see the IPL/SPL when I start it up, I downloaded the wizard service tool but It doesnt seem to work( "Warning!
A device was detected but one (or both) of RAPICommunications and Applications Policy isn'tenabled. Use first button for that purpose and try again") Ive Hard reseted it and enabled RAPI + unsigned APPS but it still wont work so Is there some other way to Get the IPL/SPL? Thanks.

I was wondering how do I find out what IPL or SPL I have on my wing??

What is the IPL anyway? And what does the update do? I mean does it make any diffence in use, that i go from version 2.09 to 2.20 ?

IPL - Initial Program Loader: Its the bootloader for PPC. It boots up SPL.
SPL - Secondary Program Loader: Loads the actual OS.

Yes, follow this tutorial and you should be fine.

Thanks for you're response Bruce.
I will try it.
Bob

Thanks again Bruce, my splash screen is changed.
But I don’t see my IPL/SPL number just the RGD tab :
R 1.02.25.19
G 52.33.25.17H
D 5nergy ROM
I understood that the IPL / SPL numbers are displayed during the boot but maybe I'm wrong.
Someone can help me?

You have to go into bootlaoder mode to see the IPL/SPL, what displays during bootup is the Radio\ROM version.
To go into bootloader mode, you hit soft reset while holding Down Volume. A tricolored screen will appear and this should display 1.90 OLINEX.

Yes I’ve 1.90 OLINEX.
So, I just want be sure, it would like to say it’s G3 wizard and I need follow the G3 guide (http://wiki.xda-developers.com/index.php?pagename=Wizard Windows Mobile 6 for newbies) to unlock my CID and update my radio ROM (my SIM I early unlocked)?

[Q] Radio and SPL IPL upgrading

I have one big "Strategic" question i have htc elf, i understand concept of ROM upgrading and what it does. However i am unsure about SPL IPL and RADIO
I would be grateful if someone explained shortly what they do and why should i upgrade them
Thanks in advance

What is a SPL? The SPL, or Second Program Loader, in conjunction with the IPL comprise a device's bootloader. Aside from bootstrapping Android, the bootloader also fulfills various diagnostic functions. One of these functions is the manipulation of data in the device's internal flash ram. Depending on the SPL installed, the user can apply a signed NBH file, flash nand images, and more. Note that the SPL is installed and operates independently of the Android build that runs atop it.
hope this helps

Re:

The most suitable SPL/IPL is the lastest version of Hard SPL avaible for your device, which opens the device to the wonder world of custom ROMs. Even if you don't plan to use custom ROMs, having Hard-SPL will enable you to use official ROMs from different carriers or HTC own official ROMs for regions that the device is sold unlocked by HTC.

RE:
Thanks People You helped me very much

HTCRT
