SPL = Second Program Loader. its a part of the bootloader, the code which runs before your os is loaded.
http://forum.xda-developers.com/showthread.php?t=455860
The radio is a term generally applied to the software/realtime operating system which runs on the cpu core that operates the gsm/umts/etc radio. On most phones, the applications and the gsm stack run on different cores because the timing requirements for the gsm stack make it unsuitable to run on the same core as applications.

Where or how can I get the radio rom 1.20.00.11.
There are Roms with it, but they are full roms. I only need the radio rom part.
Also, is the radio rom 1.20.00.11 equal to all the phones sold? Or is it brand specific?
Thanks.

use NBHextract.exe to split full nbh rom to nb files. radio part would be called 05_GSM.nb . It can be flashed either with MFG bootloader or with SSPL after converting it back to nbf (containing radio only) with nbhgen. Search will help you in obtaining this tools.

They are supposed to be. But I've got some doubts 'bout it recently (some things yet need to be researched): so be extreme carefull dealing with SoftBank devices or CHT ROMz.
So this will work if I just want to get the GPS, and not alter everything else?(language, os, settings, etc?)
and will this method leave the bootloader at the original 1.05 ?
I want to know what exactly is:
Radio Version:
Protocol Version:
SPL:
What is the difference between these concepts, ROM; RADIO; Protocol y SPL.
Thanks Very Much.
I search in the forum but i couldnt find a complete answer thats satisfied myself .
radio is the embedded software which control the phone part of the device
rom means read only memory and is the windows mobile operating system

SPL is the boot loader that also protects the phone from "accidentally" flashing software that is not meant for it.
HardSPL is the boot loader that enables us to flash all the goodies the chefs provide for us.
Hi,
I am planning to get a Diamond but would have a few general questions and have to admit I am a bit overwhelmed by the information to be found here, so I hope someone could help me a bit.
What exactly is the SPL?
I found some information at http://wiki.xda-developers.com/index.php?pagename=SPL Questions?, however am still not quite sure what it is doing. As far as it seems it is similar to a x86 BIOS which gets started at the boot process by something like a FPL (First Program Loader) and then takes care of starting the actual operating and also has control of installing/flashing a new one. Is this correct? Entering the boot loader then probably means skipping to load the operating system and entering a kind of command shell of the SPL, right?
What does a SoftSPL?
To me it seems it is nothing installed but to WM a regular application which actually exits WM and allows, respectively, performs direct hardware access, which probably serves to install a HardSPL to overcome any restrictions the original system SPL is setting, right?
Do I always need to install a new SPL?
If I get an open/unlocked Diamond and want to install third party ROMs I suppose I need to install a new SPL nonetheless as the original one always checks the ROM vendor. Is this correct?
How can I flash?
Do I always need a connection from ActiveSync or can I flash directly from the phone's flash memory without an actual connection to a PC?
Thank you.
Can nobody confirm or correct my assumptions or has further information?
Having read http://forum.xda-developers.com/showthread.php?t=416211 some questions have been semi-answered but new ones arrived .
The HardSPL does not seem to be the official term, but is the name of the "hacked" SPL to skip vendor id checks, correct?
(btw, if I buy an open/non-locked Diamond is it CID locked as well?)
The FPL I referred to previously seems to be actually the IPL which would be the actual BIOS comparison I mentioned previously, right?
Is there a reason why there is an IPL and a SPL? I guess the former can never be flashed.
Why is there the need for different HardSPL versions? Shouldnt they all do basically the same basic steps? http://forum.xda-developers.com/showpost.php?p=2437385&postcount=27 mentions changes by HTC, but even then shouldnt an updated HardSPL be enough?
It seems it is not really possible to flash/update from the internal memory but an ActiveSync/Windows Mobile Device Center connection is necessary.

The SPL seems to be started by the IPL (what I referred to as FPL previously) and can boot the actual operating system but also flash new ones.

HardSPL is actually the name of the modified/hacked SPL available from here, which allows the flashing of non-official ROMs. As long as you want to install official ROMs (from HTC or your provider, if branded) the modified SPL should not be necessary. For all other ROMs it is.

As far as it seems there are not as many versions from different people as I thought but only different version numbers, which seems to be due to different versions shipped with the devices. Generally the newest version seems to be recommended, however sometimes a previous one might work better.
Apart from version numbers there are however two actual different HardSPL versions, one which only allows signed ROM package and one which accepts all. The former is the more secure one, as only signed (and so by the xda-developers.com community approved) ROMs can be installed.

http://wiki.xda-developers.com/index.php?pagename=SPL Questions? seems to provide a good explanation.
A SoftSPL seems to be a workaround if the system's SPL does not allow the flashing of a new SPL. It is a WM application which you need to run on your phone and runs as SPL, allowing to install a new SPL on the machine.

The default SPL coming with the device only allows ROM installations from the official vendor (either HTC itself or the provider if it is branded). As long as you install only those official ROMs you shouldnt need to install HardSPL.
All other ROMs (in particular those here) need HardSPL however.

As Andrea already mentioned flashing the Radio and ROM from the internal memory is possible, flashing the SPL itself is not as far as it seems.
First of all, i am very sorry if i made a stupid Question because of my noobs. But i am preparing to flash DangerSPL onto my G1, and still dont know which radio should be chosen. I've been spending hours reading info from several posts on xda but cant find answer yet
There are two radios compatible with DangerSPL
2.22.23.02 for T-mobile/US
2.22.19.26i for Non-US
My current radio is 2.22.20.23
That's what I can't get through. My G1 is a QWERTZ one, which I guess it's a Non-US and 2.22.19.26i is better for me? But the first one is mentioned much more frequently in posts, means it's famous/or better than the other?
Please help me figure out
Thanks very much, and sorry again for my stupid Q

Ok, to be successful. You will need to FLASH the radio before the SPL.
You can find both the radio and SPL here http://code.google.com/p/sapphire-port-dream/
DO NOT attempt to downgrade your radio at anytime after installing this SPL as it WILL brick your phone.
If you have additional questions you can read up on the thread here >> http://forum.xda-developers.com/showthread.php?t=517593

Please make sure you read all the posts first before you flash your phone. I hope that helped.
ok thanks much for your help
But those stuffs have been reading over and over by me, and i still can't find out which radio should i flash. The 2.22.23.02 (which refers to smth more common and used by more people) or the 2.22.19.26i ? The sapphire-port-dream website says that the 26i is the latest version
This my first time flashing radio and upgrading to DangerSPL, so i'm very scared of bricking =.= Can you figure out for me which one is for my phone ? Thanks ^^
BTW, my board is a PVT one, rooted, but the very first bootscreen contains a grey and blur G1 in the center and a "T-mobile" (with the red T and four white dots like in the logo of T-mobile) at the bottom of the screen. It's not the all-white-big-centered "T-mobile G1" like most of those i see on the google or youtube. Is there anything important ?
(I can't post images along with this bcause of the new member's restricted right, so i will attact them instead. The worse quality one is mine)

Splash screen can be changed. To check go to bootloader, power on the phone holding camera button and see what do you have..it will show if you have 32A or 32B board.
1.33.2003 is compatible with 1.x and 2.x radios
1.33.2005 is compatible with 2.x and 3.x radios
So 2.x radio is safest. The combination has to be maintained otherwise you can brick the phone.
DO NOT INSTALL DEATHSPL!!!!
There is NO REASON for it!
What people use it for is obtaining a different flash partition layout on the internal memory. THERE ARE BETTER WAYS TO ACCOMPLISH THIS!!!!!
http://forum.xda-developers.com/showthread.php?t=717874
The DEFAULT setup of this yields you a SYSTEM partition that is the SAME SIZE as deathspl, and a USERDATA partition that is ***FIFTEEN MEGABYTES LARGER*** than deathspl.
Install SPL 1.33.2003 (ending with a THREE) and any 2.X radio ***IN ANY ORDER IT DOESN'T MATTER***. ZERO brick risk, and SUPERIOR to deathspl.
Further information;
1) PVT/DVT, DESPITE what some of the feeble minded morons who don't know what they're talking about claim, ****IS IRRELEVANT****. There is *NO DIFFERENCE* between a PVT and a DVT.
2) ALL DREAMS (100% there is not a SINGLE exception) are 32B. The ONLY device where there is any question of whether it is a 32A or B is MAGIC.
Thanks so much lbcoder
It's because i think that deathspl is the only hope in order to get to Cyanogen or CaNNoN roms. And flashing radio and spl somehow is the most risky step :|
Did you mean that, by following that Firerat's guide, i am enabled to flash SPL 1.33.2003 and radio 2.xx in any order? Is 1.33.2003 deathspl or not ? And i want to flash CaNNoN CE 2.2.1, so is this good for me
^^ Thanks again
It doesn't appear that you bothered to read either what I said or the thread I linked you to. READ AGAIN!
There is NO BENEFIT TO DEATHSPL. It does NOTHING USEFUL. There are BETTER WAYS to accomplish the same thing that do NOT involve ANY kind of RISK!

The SPL has NOTHING to do with what you can flash to the phone. You do NOT need deathSPL. It is POINTLESS. The ONLY thing you accomplish with the deathSPL is that you RISK BRICKING YOUR PHONE!
I suggest the 1.33.2003 SPL because it is a FULL ENGINEERING SPL that is 100% compatible with 0.95.x000 (the SPL that your phone SHIPPED WITH). **IT WILL NOT BRICK**.
Using the recovery-installable patches supplied by Firerat will enable you to flash ANY system image to your phone. NO EXCEPTION.
Ok ok. I am a stupid man, so please don't blame on me ^^
Let me ask a very last question. As i can see from your advise, after flashing those CustomMTD, i can flash ANY system image(ROMs) to my phone without upgrading to 2.xx or the pointless dealthy spl. Is it right? In other words, i still can use CM or CE roms with 0.95.x000 radio?
And is it harmful or not if i want to upgrade to 2.xx radio? (still want smth new :"> )
well, no one ?
0.95.x000 is default SPL, not radio.
You have to flash new SPL (if you're still on default), but not Haykuro/Death/Danger/Apocalipse (1.33.2005) which is not compatible with 1.x radios (and this is common reason of brick), but so called SafeSPL (1.33.2003) which has same low-level access to phone (fastboot, so it's giving you as much as 2005), but it is compatible either with 1.x radios and 2.x radios, so there is no chance to brick.
After you have engineering SPL (2003 or 2005, but in this case we're talking about 2003) you can use MTD Partition Hack to change partition layout on your phone (same thing that is Haykuro doing, but now you can manually resize them in order to get more place for apps in internal memory). This is needed for 2.1+ and Sense ROMs, because they do not fit in standard 70 mb /system partition (they need 90).
When you have both new SPL and /system big enough, you can flash EVERY ROM you want. If there is requirement for HaykuroSPL in OP of ROM thread, IGNORE IT. This is requirement for 90mb /system partition, which now can be achieved also by MTD PH.
Upgrading to 2.x radio is recommended, new radio means better signal reception and less battery drain.
Thank you very much raven. Your answer is very clear and kindly. So, now I have to flash SafeSPL, then MTD PH, and after that I can use any ROMs, and 2.x radio are optional (can flash or not, can flash after the safespl, it doesnt matter) right? I am so excited. Thanks again
I think this order is correct:
Custom recovery (Amon RA or Clockworkmod, ignore this step if you already have custom recovery)
SafeSPL
MTD PH (recovery patch)
ROM flash
MTD PH (ROM/boot patch)
Optional: 2.x radio.
I am glad to help and your thanks made my day . Just remember to put
Code:
90 2
in mtdpartmap.txt on root of sd card to prepare enough space for 2.x ROMs. You may also have to fake Haykuro SPL, which is simply done by editing mtdpartmap.txt in this way
Code:
90 2
spl 1.33.2005
Remember to patch recovery, wipe data&cache&system, reflash/nandbackup ROM and flash boot patch after every change in mtdpartmap.txt.
Thanks again ^^
But i still have a minor question before flashing all those stuffs. Raven please view this post :here and give me an advice whether i should continue according to lbcoder or not ?
quite useful infos. i was about to flash deathSPL, but the fact that the MTD layout gives me 15mb more space, not to mention it cant brick, seriously tempts me.
hey.
Im almost sure i just bricked my g1, just need to be sure.
I was running Death SPL and the last official radio, and had gsm\umts network connection problems.
Decided to upgrade the radio to the last one that came out recently, i did, the problem seem to be better but it got worse in time.
downgraded the radio, and tried around 15 different roms, all tries with the same outcome.
so after a lot of trial and error, i decided to get back to one the the first radios available, but i was afraid it would brick my phone so i read carefully about it
I had a realy hard time finding something but i everntually came across a couple threads that stated that it was ok to flash any radio, as long as the SPL was flashed first...
after reading that i downloaded a 1xxx radio and flashed via recovery...
result: stuck in the G1 screen...
My question: phone in the crapper right?
thanks for reading guys

No, what they said is that it is OK to flash anything as long as you use FASTBOOT INSTEAD OF RECOVERY, and that FULL FASTBOOT (with this ability) depended on having a 1.33.2xxx SPL.
With an SPL and RADIO that are incompatible with each other, it is impossible to successfully boot the kernel. Following a flash-hboot or flash-radio, the system is set (via writing the command field in the MISC partition) to boot-recovery. When in boot-recovery, the phone IGNORES all user inputs. The incompatible radio/spl fails to boot-recovery, and you're bricked.
USING FASTBOOT INSTEAD prevents the misc partition from being set to boot-recovery by writing the SPL or RADIO directly. As a result, when you reboot, though it still won't be able to boot a kernel, IT WILL RESPOND TO USER INPUTS and bring you into FASTBOOT mode... from where it is possible to, again, flash radio or spl.
Your failure is a result of failure to read properly.
SPL/radio compatibility:
0.95.xxxx, 1.33.x003: compatible with 1.x or 2.x radios.
1.33.xxxx (except 1.33.x003): compatible with 2.x or 3.x radios.
No exceptions.
I always suggest using the 1.33.2003 SPL since DREAM should always use either a 1.x or 2.x radio (except robbers in canada, because they are bastards, but you can load those with a 2.x radio just fine). 1.33.2003 is the strongest engineering SPL available, and fully compatible with the proper radios. There is NO ADVANTAGE to any other SPL -- no, you don't need to change your SPL to reallocate storage space.... in fact, limiting yourself to SPL changes to do this will tend to waste a lot more space (15 MB more available than 1.33.2005 gives you).
