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??

maybe you can repair your bootloader now.
I have an idea of how you could do it with g3.
Is your cid locked?
Is your phone g3 or g4?

phone
its g4 xda neo cid locked
UPDATED NOW NEW TESTS DONE. IPL SPL = 2.21
if i use prophet roms now everything is slow on device not usuable. i have to use wizard roms LOL. only problem then no sound is working. but replacing dll from prophet gives u sound back again. ........ THIS IS ****ING BULL****. anyway its usuable again now. i flashed now the fucing pbootloader of wizard into my device..........................
Hardreset does not work anymore if holding camera and other button it goes again back to bootloader now i need to find out how u do a hard reset on wizard LOL.
anyway i need a IPL AND SPL From prophet ............... extracting ipl and spl from qtek prophet and traslating it making a new nbf results in a flash process but after i stays on old IPL SPL ....................... ill report soon more about this strage problem having a wizard bootloader on Prophet.

omg this is ****ing weird
that that works is really strange^^ thank you though again you rescued my device hope its gonna work for me I'll report in the next days...
so if I'm doing thats right the whole thing is working, while you are connecting the wires get don't plug the wall chargare in so you don't have elictricity and cover up the rest of the pins im not sure if thats necessary but you don't wanna brick your phone even more the phone is turning of though as soon as you disconnect the wires... i'm having a prophet rom on it right now i'm trying a wizard rom now...
alright im running the wizard aku 3.2 rom now. its working very well except that i have to wires coming out of the back of my pda.
but ipl downgrade might be possible from there... so thank ýou alot the solution works

your welcome
i will make a paypal account now so u can donate me i guess this solution is very good and no need to pay for it =)
UPDATE: IM NOW ON 2.26 TMOBILE WIZARD NOW WITH IPL AND SPL 2.26 THIS IS WORKING ****ING GOOD AND TRUST ME ITS FASTER THAN MY PROPHET WAS EARLIER WITH PROPHET BOOTLOADER.
GET THE TMO 2.26 from FTP and flash it. it will update ur device (IPL + SPL )too 2.26 never mind of it
IPL DOWNGRADE is NO PROBLEM FOR ME u can extract rom hex edit the ipl part and version number i did that already my ipl now is again to low number (custom) 2.01 but spl i coudnt find out to edit. im working with winhex and primary memory editing since this is very dangerous i dont suggest to do it. only experienced users should do that
WARNING WARNING WARNING !!!!
I WANT TO REPEAT AT THIS POINT AGAIN DONT TRY THIS ON WORKING DEVICE!!! ITS JUST A SOLUTION IF UR DEVICE IS ALREADY DEAD!!!!!!

can u take a pic for the wires?

wires
NO need to i will explain in detail.
1. Take ur phone and put it on ur table =)
2. Turn it so u can see the camera
3. On the right u see 6 Pins.
4. The Pin 1 is nearest to Camera
5. Pin 5 would be far away from camera.
u got it now ?

it worked for me with the sixth pin to by the way but that might be why it doesn't work without the wires for me yet.
did you cover up the other pins alphazero?
you were able to flash a lower bootloader back onto the device right with some kind of hexedit application or something?
I think a lot of users would be glad if you could upload a rom that can downgrade the ipl and spl including me , as you said it requires a lot of skill to cook the right rom...
thanks man

Just a quick one. If you can downgrade the ipl and spl to 1.xx.0000 or 1.xx.0001, could it be possible to do CID unlocking?

Downgrade
I could do compile a rom that downgrades ipl to whatever u want. the spl is coded and i need to find the place in a spl rom where version id is written.
i found out that the update rom process checks version id.
so theory is fooling of a lower rom a higher rom id. this means your downgrade rom will have a higher rom id.
im working on it right now. i have to do some test on university right now like many others please be patient.

Status: IPL DOWNGRADE OF ANY G4 successfull !
SPL DOWNAGE OF ANY G4 under work !

haha be patient and 2 minutes later you post it
spl 2.21 is working normally on the prophet anyway doesn't it?
can you upload that downgrade?

how is it coming ...did you find out anything new?
if you manage to downgrade ipl and spl to prophet version you are where you were before you flashed the wizard rom right?

answer
yes it would solve the accident wizard g4 rom flash on prophet!

but isnt spl on the prophet 2.21 anyways and only ipl is 2.15?

Dear Alphazero is it possible to solve wrong flashed g3 with jesterz g4 rom so now i can be only in bootloader mode and i can start flashing my prophet but please tell me how and what with On my bootloader screen now is written IPL 2.10 and SPL 2.20.0001. Please help me repair my prophet if it is possible
Should I do something with cutting battery pins?

uhm no the battery pins was because our device did only turn on if it was plugged into the charger, which meant you couldn't plug it into the usb at the same time to flash a new rom.
your problem is different and can't be solved with that solution... sorry sd goldcard i guess

Yes but i can only connect to mini usb and from bootloader i can flash it with battery full so please tell me shell i cut some pins from the battery and what with should i try to flash

HardSPL doesn't seem to update SPL version

Hi I have a G4 Prophet and the IPL and SPL version number reads 2.10.0001.
I would like to flash it to use a WM6.1 ROM with the touchflo type functionality and new IE Mobile features (i.e. zooming).
I have read through all the guides about carrying this out and have even started having a go but am getting confused about HardSPL.
From what I read HardSPL CID Unlocks your phone so that you can install a diffeerent Carrier (e.g. Orange, Vodaphone) ROM ... or in fact a home 'cooked' ROM off of this site.
I have tried manually carrying out the HardSPL using both the Prophet Tools GUI and the command line batch file HardSPL however after the procedure finishes my IPL and SPL do not read differently as all posts indicate (i.e. they do not read 2.G4.4PDA) ... instead they remain as 2.10.0001.
I have seen the phone go to the tri-colour bootloader screen and even the progress bar go up correctly however when it reboots it says 2.10.0001. I'm assuming that I cannot go ahead and flash with a ROM (such as the Shadow TE one until the SPL reads 2.G4.4PDA).
Can anyone offere me some help with getting to this?
Many thanks.

I would recommend you use something like: http://forum.xda-developers.com/showthread.php?t=353547 It makes it a one stop upgrade... That uses "JumpSPL" rather than HardSPL which is the short term option.

Thanks for the help I tried the alternative lazy tool and it worked (http://forum.xda-developers.com/showpost.php?p=2141436&postcount=188) now my Orange SPV M600 has the Shadow Touch edition rom on it with the shadow cube addon, so far works a treat.
I would still be interested to know why the SPL version number did not change using the prophet tools or HardSPL on its own.
Anyway many thanks again.

What is your devices IPL?
It may be because Soft/Jump SPL was not executed properly prior to HardSPL (this is automated through the HardSPL tools and Prophet Tools).

Upgraded from 2.09/2.09.000 to 2.20/2.20.0000 No Upgrade to WM6.1 possible

Hi guys,
im sorry thar I have to ask. In the last 3 days, I´ve read a lot, but I can't find any hints for my Problem.
Fact is: I updated ma IPL/SPL from 2.09 / 2.09.0000 to 2.20 / 2.20.0000.
So if I want to flash my ROM - for example with this, after rebooting the prophet it stucks in the red/green/blue screen, showing IPL 2.20 and SPL 2.20.0000. In the lower left corner is 'USB' shown, when USB plugged in.
I tried to flash back den WM5 - it works, so that I can use my Prophet again with WM5. BUT I WANT WM 6.1 .
Can please anyone give me some hints, or tell me what I`ve made wrong.
I have no further Idea.
Thank you all for your answers.

GOT IT.
I simply did the HardSPL (including the SoftSPL) once again. An what should I say: Miracles happen . After this in the bootscreen was displayed: IPL 2.20 / SPL 2.G3.4PDA. And now it´s possible to flash each ROM - great
Best regards

What is SPL?

Hello there!Im a newbie here....since I got a HTC Dream I have solve lots kind of questions but there still have one remained.......what is SPL...? I saw there are two different type between SPL and USPL.....That's getting me weird

Welcome to forums
SPL - Second Program Loader is a boot loader after IPL (Initial Program Loader) often seen on smart phones and PDA:s.
SPL is similar to a BIOS in a computer and can be flashed and updated.
The version format of SPL looks like this:
x.xx.xxxx (Example: 2.17.0001)
If the SPL ends with 0000 it is a G3 Chip and ending with 0001 shows it is a G4 Chip.
Please read the Wiki!

thanks!
thank you for your answer!

So SPL is what people normally call the bootloader or?. Im trying to figure out how this relates to the HTC Desire
