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??

Warning for Newbies

Hi Guys,
i pointed out that if you have G4 you wont be able to bring it back to the original stand-so you will loose your warranty in any case if you update your G4 model with new ipl/spl cause so far i know there is no way to downgrade it again.You wont be able to install original Software until your device is CID locked and there is no solution for cid unlocking for G4 so far.

There is no free CID unlock, it's different
And you be able to install original software but not able to install official Operating System from other country , really different.

you can flash any Rom you want without any CID unlocked, just you can't downgarde the SPL, so just remove the SPL from any rom, so you are the Newbie here, there was a lot of threads bout this, sorry
IPL SPL, the software that runs the hardware, it is like bios of the motherboard or firmware of any hardware, it is important to update them

ähm sorry...but in any case -then tell me please how to get back the warranty it is not possible or?if you update ipl/spl what happens normally just by updating your os with the files you can download from here-gullums etc. then there is no way back to install the original updates from o2.Sure you can CID unlock for money- who wants that?i want it for free but there is no solution.So i started this thread juust to warn noObs not to update cause there is no way back without paying.got it? also i flashed my phone without ipl/spl i ve never said it doesnt work but i guess doing that wont give back warranty cause they also check ipl and spl and see that the device has been upgraded with some other versions->warranty gone.So instead of telling me what to post and saying that im the "dumb" you should bring solutions or simply not comment this thread-cause nobody could helped me with my problem i got no answers,so now to answer this thread is anything but not useful-sry guys my opinion

please check this http://forum.xda-developers.com/showthread.php?t=300356

thank you for this thread but i already know it,even it is possible to install the different os versions without CID lock by following steps in this thread you wont be able to use the updates provided on the O2 site and IPL / SPL is still different to the originial ones-i wanted to sell my phone i have 1 year warranty left but i guess it doenst matter-who would buy a prophet with warranty if O2 would say it as none,cause it has being modified and who would buy a prophet if you are not able to install original software without spending money for this or something like that.but thx for your help

online warranty, will check the SPL? is that what you mean?
you may wait for my solution to write SPL using pdocwrite,
IPL can be downgrade without any problem, only spl has the problem, and if you write the SPL using pdocwrite, and install all using nb2nbf it will be again your old phone

SPL has nothing to do with OS, if you just install os.nb and extention.nb, no one can check it online,
I think, you may download your o2 orginial rom, and extract the nb files, make new one without only SPL it will work and maybe the supports guys will not notice, it will be your phone again
untell I write how to write the SPL using pdocwrite, if you restore your old SPL even the HTC support can't notice you istalled other roms

I had 2 modified prophet back to warranty and they don't check the IPL/SPL stuff.... lol do you think they care about that ? And spend a tech to check dead devices for boot loaders ? no way
Maybe HTC do, but then they don't care anymore.
You just have to put your old rom back.... if you had back it up or are able to find a download that suits.
@paradis_pal: if I understood correctly, your solution will downgrade the IPL/SPL but with a higher version number to fake the protection, so it will still appear as modified

no, using pdocwrite will flash 2.20 again
and you misunderstood me, I was writing what charliess was thinking, I think no one will check the SPL as you wrote, if you read my first post in this thread you wouldn't misunderstood me

G4 Help plz

Hi,
Im have a G4 mda vario!
ipl 2.21.0001
spl 2.21.0001
original software t-mobile.
Im trying to figure out the best way to upgrade to wm6. Some topics say to unlock CID but with a G4 you must pay for it. Other topic say use hard spl or soft spl is this also for CID unlocking?? I dont know annymore so can someone help me?? The steps I need to make to install wm6 on my device.
And for the best wm6 rom on htc wizard aka mda vario.
Thnx!
Kevin

i have tmobile mda vario
i am running tnt 1933 which seems to be for me at least the best all round rom. and its as stable if not more than stock wm5
i used soft spl.
you should read the instructions fully and make sure you are happy before proceding.
I recommend.
1) Hard reset
2) hook up to pc and run wizard service tool (search the forum) and use this to enable rapi and cert etc.
then run the soft spl.
I had problems first couple of times where it would go black then i get funny error in green text but never actually flashed anything. But i think the hard reset and enable rapi stuff fixed that.
hope thats of some use.
cant recommend tnt rom enough

if you want to save yourself an absolute tonne of mucking about and trying to figure everything out, i recommend you splash the cash and pay the £20 on http://www.imei-check.co.uk/
i have a g4 and used these guys, worked with absolute no issues, and im on the xmr5 rom ( or whatever its called )

the above recomendation are good , in fact that's what i have done to update my G4. I would only add to that rembember to save your current rom and extended rom before update. so you may downgrade if you have any problem with wm6.

How I flashed my TYTN-II successfully without HARDSPL ?

Hi,
I purchased my TYTN-II from UK as sim free in Oct-07. From the last five months i was under the impression that HARDSPL is very much necessary for flashing. Though i never tried to HARDSPL my unit. Last month there was RUU upgrade from HTC e-club. Since it was from HTC and there was no special instruction before running RUU. So i run the RUU directly and my unit was successfully upgraded to WM 6.1.
After that i realised that 6.1 is not stable. So, with the help of the forum ... i downloaded the WM 6 shiped RUU from the forum and run directly and again my device accepted the WM6.
Now, i am confused that how this happened ? am i not suppose to HardSPL my device before flashing specially at downgrading level ?
OR since my device is SIM Free / Unlocked thats why it doesn't need HardSPL ?
I am just trying to educate myself nothing else ...
Regards

i believe that u still need to hard spl the right spl for that rom u installed...the spls are stickied in this forum
admins = plz shut this thread down...

I always thought it was normal for sim free phones.
I could just be thick. But I thought it was due to networks and simlocks that people had to HardSPL.
So its just for cooked ROMs. I get it now. So you flashed a HTC ROM on a HTC device. Which would have flashed the correct SPL anyway.

Hard SPL's allow you to flash cooked roms safely without bricking the device. Since you flashed an official rom from HTC you wouldn't require a modded SPL

There are different hard spl's for wm6.1 thats all. To be honest you are normally safer just to hardspl anyway. Back in the day, if you hadnt hard spl'd your phone and you bricked it, it was basically impossible to fix. Not sure these days on the kaiser, i have never tried not hard spl'ing mine so i couldnt say.

OEM SPL does NOT allow you to downgrade even if the ROM fits your device. I don't know why you not taking HardSPL, if you worry about the warranty, just go ahead to flash ROM with HardSPL, then flash OEM SPL back after it.

if you device is from HTC and not locked to a provider you can flash roms from HTC-E club BUT!!! your phone is not truly safe HardSPL is like a condom for your kaiser if something happens lets say the USB plug comes out while flashing NOT having HardSPL you might have an issue BUT you probably WILL... Just do yourself a favor and flash HardSPL you can always revert back to the shipped SPL if you need to for a warranty return......

T-Mobile Germany original ROM incl. Radio SPL and so on (badly needed)

Hi Community,
my mda vario III (HTC Kaiser) is an waranty case and i badly need the original rom incl all, this one in the forum is only the OS without radio spl and so on.
best regards
HT

I also needed it, bust just installed the OS and a working Radio.
T-Mobile does not even care what is installed, i guess they don't even startup the device but send it straight back to HTC. I switched about 20 T-Mobile HTC Devices and it worked everytime to just install the OS and a working Radio.

If you know the Radio and OEM SPL version you can probably get them from this site somewhere. They dont have to be extracted from the Dumped Shipped ROM.

Ah, Just have to see if anyone knows the OEM SPL and Radio versions.
Does it have to be WM6 or Wm6.1 Versoin, or are you not bothered. I don't think anyone will care so long as it is a T Mob stock version.

You can download the latest German ROM from the T-Mobile website
