What are SSPL, HSPL and Radio?

---

I swear I have used the Search tool, but lots of topics have HSPL in their title, and I weren't able to find any FAQ topic talking about that.

Everybody here talks about SSPL, HSPL, how to use them and so on. The only think I understood is that to flash custom roms you need HSPL, and for official roms SSPL is "enough". Could anybody tell me something more and explain me why do we need this stuff to flash a rom and not just run a .exe on the device which could do everything automatically?

I also didn't understand what the Radio is. I thought a part of the rom which manages the GSM/3G antenna, but I think I am wrong.

Thank you in advance

okay

spl = Secondary Program Loader. Think of this in the same sense as bios on a pc. (it sets where your system boots from, intialises sub system process etc)

sspl = soft spl (this allows you to flash another spl or hardspl).

hardspl = hard spl .. basically it allows flashing of any rom. It protects you from bricking your device. If you have a bad flash it just forces the phone to load into bootloader, from where you can flash another rom using pc or storage card to get your phone working again. Using a hardspl you can flash any carrier rom without cid unlocking your device first.

Radio = you are correct about your assumption as to what a radio does .

Now if you are flashing your carriers official rom than you don't need any of this stuff but different carriers set their cid in their roms so only phones that have their cid can flash those roms ... now if you like the wwe htc rom and want to flash it onto the tilt you will first need to hardspl your device or otherwise you won't be able to flash the rom ... it will time out with an error telling you invalid vendor id.

Many thanks! Now it is much clearer! Just one more question: why do people care so much for the radio and post their radio version to their signature? Is the radio revision so important? Why is it not just part of the rom?

Thanks again!

well radio is definitely important ... i mean if you have a uncompatible radio you will loose sound, camera, connection etc on your phone. Reason people list the radio they are using is basically to let others know what radio is working for them on the rom they have. This way if someone else doesn't know which radio to use with the rom than can use the radio they have listed. Radios are location dependant. Some radios give better reception here in states while others give better reception somewhere else in the world.

Most of the time chefs will include a radio with their rom, but some leave it out so you can choose the one that works best for you. Just a keynote to keep in mind when selecting radios is that wm6.1 roms need wm6.1 radios and wm6 roms need wm6 radios. Also DO NOT flash a radio that is intended for another device i.e a rapheal radio onto a kaiser (this will brick your device). There are exceptions to this rule. Also you should get your phone security unlocked before proceeding with flashing various kinds of radios. This will save you from getting stuck with a radio that locks itself to the device (thus rendering itself unchangeable; no matter how many times you flash another radio you will be stuck with that radio) an example of this is "the radio from hell" which alot of people in the kaiser forum got stuck with and weren't able to get rid of it until "FrankenKaiser" came along.


Hope this helps.

Thank you, it does.

Another term I read is Jump SPL. What's that?

Some poeple encounter problems trying to flash hardspl, Jump spl "jump starts" the process.

(problems like the kaiser white screen issue here)

Ok, thank you all.

Now I only have to wait for the Blackstone Hard SPL.

aren't we all ... hold tight though they are close to getting it done.

How do you know that? In the placeholder topic there has been no update about the development status since a while.

WOW!!

Just wanted to say a HUGE thank you to thesire and joel2009 for being so extremely nice to a newbie!!! This is probably one of the first posts I have seen where a newbie doesn't get their head bitten off for asking a question. (I don't think I've ever asked a question for that very reason! LOL)

I was searching for the answer to 'what is SSPL' because I couldn't find it in the Wiki acronyms section. What a pleasant surprise! Sorry if this steers away from the topic but I just could NOT pass over this thread without saying THANKS!!!!!!!!
