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.
never Mind I didnt enable the cab file within My wing Thnxs XDA Community ^_^
I was wondering how do I find out what IPL or SPL I have on my wing??

IPL 1.000 ????? Any problem to upgrade to AKU3.3????

i find that the number of IPL shown in bootloader is 1.000....
IPL 1.000
SPL 2.15.000
GSM 02.19.21
OS 2.15.23.27
is there any problem to upgrade to AKU3.3.?....
i did a little search in this forum...and IPL for the others are always 2.xx.00x...
i know that i have a G3 modal....and i 've unlock the CID...(but i wonder if i did it successfully...)...
push~...help me
I've experienced it but no solution unfortunately...​
There should be no problem, just make sure you update to a 2.20 ROM first before you start upgrading to an AKU3.x or WM6 ROM
My IPL after unlocking and upgrading to WM6 remains 1 but SPL is 2..how to make both of them 2?​
I posted IPL 2.10 for G3 search for it
nope...no problem at all...
mine had a plan upgrade IPL/SPL to 3.08
haven't tried it...
but mine already aku 3.3
it works fine..as he said,don't forget upgrade to aku 2.2 as "starters"
what's the purpose and benifit to ungrader over IPL 1.0?
exe read what do IPL and SPL mean in the WIKI, it is like the BIOS of the mainboard in PC, basic inpot output system
I did as you suggested and found nothing regarding IPL SLP in the wiki. Lots of link on there does not display anything when clicked.

What's diff. between IPL/SPL 2.26 with 3.08?

I use Cingular 8125 with IPL/SPL 2.26 and OS Xplore 1.1 and Radio 2.19.
Now I down load IPL/SPL 3.08 should I upgrade ornot?
Thanks

Cannot upgrade to any WM6

Hi guys.
I have this iMate Kjam (Not mine). It was with a T Mobile Official ROM and has IPL/SPL at v2.26. I checked and there was no G4 sign anywhere. Someone had to remove the CID thing to this. I downloaded several WM6 ROMs but once the complete flashing and the device reboots, I'm still in the T-Mobile ROM. I down-flashed to the age-old Button Love WM5 base ROM and here is the ROM status:
IPL: 1.01
SPL: 2.26
GSM: 1.12.10
OS: 1.5.4.2
If I upgrade from this point with, let's say, TNT5.0, here is what happens:
IPL: 1.01
SPL: 2.26
GSM: 1.12.10
OS: 1.5.4.2
Same right? but all the graphics change when booting. There is the HTC logo when device is turned on and there is the TNT 5.0 "BOOM" title when OS is loading (with the IPL/SPL/GSM/Radio)
Can someone tell me what is going on? HardSPL (http://forum.xda-developers.com/showthread.php?t=332320) clearly tells me that device is NOT G4

Update:
I was able to install the official T-Mobile ROM onto Button Love ROM. Here is the screen statistics:
IPL: 2.26
SPL: 2.26
GSM: 02.25.11
OS: 2.26.10.2
If I try to upgrade to WM6 now, nothing will happen as I've already tried. After the flash process, it will still be official TMobile...
What should I do now? If I compare the properties of this Wizard with my own, I'm pretty sure this should be a G4 device.
Flash Buttons ROM again and do a CID unlock. That's it! Have fun!
I have a G3, but I had to flash Button twice so that the IPL/SPL matched, then I unlocked and reflashed 2.26 stock (again be sure that IPL/SPL match numbers), then from there I joined rom flashers anonymous!

The only avaliable HardSPL tool doesn't recognize the device as G4... so how do I forced CID unlock? I tried SoftSPL... but at that time, my IPL and SPL were different...
Lets face the situation
IF you have
IPL 2.26 or 1.xx
SPL 2.26 or 2.XX
You have a G3 device - forget do not use Hard SPL or Soft SPL, these are ONLY FOR G4 DEVICES
Since you have a G3 Device you have 2 options
If you have IPL 1.xx and SPL 2.xx . use WST (Wizard Service Tools) to unlock your CID device
http://forum.xda-developers.com/showthread.php?t=329170
Note that only with IPL 1.xx you are hable to unlock your CID with WST
If you have IPL 2.xx and SPL 2.xx, than you must downgrade both to IPL/SPL 1.xx with an official ROM
Before you do something, install WST in you PC, and check the real situation of your device

Excellent.
If I'm on Button Love ROM, I have IPL v1.x ad SPL v2.x
Should I upgrade to WM6 from here?
If not, then I have to upgrade to Officia T-Mobile ROm. Then IPL/SPL = v2.26 but WM6 won't flash...
Ah ! c'mon guys

Ok, if you are on IPL 1.xx and SPL 2.xx, you can use WST-Wizard Service Tool 4.2.2 to CID unlock
Then you should load a carrier ROm T-Mobile to get IPL/SPL 2.xx
But allways read as mentioned in the previous post

Great forget my last post

I have a Problem

Hello, My English is not please not bad so well thus its. I am quite again and have several questions. Which is IPL and SPL on the boat screen on my MDA Vario? I wanted it gladly bottles however it went not as I wanted. My Bootscreem data is:
IPL 1.01
SPL 3.08
GSM 02.25.11
OS 2.26.10.2
If you have downgraded by flashing Button's Rom 1.05 for CID unlocking,then reflash the button's rom once more to get SPL 1.xx also and use lokiwiz02 tool to CID unlock,otherwise download WST_4.2.2 from the below link and run it to CID unlock the phone,after that upgrade to IPL/SPL 2.xx by flashing T-Mobile 2.26 or any AKU 2 official rom and than you can upgrade to any wm6.1 latest roms.
WST_4.2.2 :-
