What exactly is hardSPL? USPL vs hardSPL

I apologize in advance if my questions are trivial and I am just dense.
I am pretty sure I've read through all the threads for "n00bs" but I still can't get a grasp of what exactly hardSPL does or is. I ran the search function and found that I don't NEED it per say and has claimed that it actually is "safer" to use USPL.
I own a Tmobile Wing (IPL > 4.xxx)
1. What exactly is the difference between USPL and hardSPL?
2. What are the limitations of either one.. will flashing a cooked rom without hardSPL cause problems?
3. I currently have flashed the newest Open Touch 4.0 and haven't had any problems at all (USPL), but I noticed in the thread for Touch-IT, it says that hardSPL is required. What does that mean exactly? If I flashed it w/o hardSPL.. will my wing crash/brick?
4. At some point, I'd like to sell the phone, so I don't want to do anything that is irreversible. My understanding was USPL is reversible, hardSPL is not?
5. I was on the verge of flashing the hardSPL but chickened out.
I installed the three cab files (canonyang.cab aserpolicy.cab disablesecurity.cab) but decided I wasn't ready to flash.
Will that cause any problems (installing the .cabs but not flashing)?
any help/input would be greatly appreciated. Sorry for all the n00b questions. Thanks

Essentially what you are doing is changing the Bootloader so you can install a different ROM regardless if it's signed.
USPL and HardSPL is a matter of having it done temporarely or permenantly.
USPL (temporary), is the safe route. This will allow you to Install one USPL capable ROMs per USPL. So if you're not a big flasher, and thinking about selling your phone in the near future, then you might want to stick to this method.
HardSPL (permenant), is the only TRUE way of bricking your phone. You will flash the bootloader for good so that you can constantly flash new ROMs without having to worry about flashing your bootloader of making sure it's a signed ROM. For heavy flashers, like myself, this is the ideal route.
HardSPL is reversible, there are some threads on how to do that. If I remember correctly, you have to flash back to a Stock T-Mo ROM.
Some ROMs require HardSPL because sometimes the cooks use different methods to flash ROMs onto devices other than ActiveSync (which is needed for flashing via USPL).
For example, ttran001's Open Touch V4.0 Micro ROM flashes onto your device using your SDCard, the phone is never connected to you PC so no opertunity to USPL. If it was not HardSPL'd, the ROM would be rejected. If it was, the flash would continue flawlessly.
I hope this answers your questions, and please, if I got anything wrong, correct me.

Oh and from what I understand, installing those cabs wont hurt your device if you dont HardSPL. I believe you can uninstall them from the "remove program" which can be found under Settings/System/Remove Programs.
Everyone's allowed a Noob question every now and then I only know all this info because I read, so im sure if you read u'll be just fine.

nKiwan, thanks for quick and throrough reply
I get a little lost with this:

what does that mean exactly?
perhaps I should start by asking the USPL acronym stands for - I've googled it and I couldn't find the right acronym.
From my understanding.. the only real difference (besides one uspl rom per uspl vs infinite - i'm still a little hazy on that) is that hardSPL allows for flashing outside of activesync?
thanks again... I swear I tried my best using the search function and reading

Well, correct me if i'm wrong, if you do not HardSPL, then you must USPL your device everytime you wish to flash your device. This will temporarely change your bootloader so it will allow you to flash a non signed ROM, a.k.a. an "outside" ROM. USPL capable ROMs, are ROMs that you can flash using USPL, therefore, ActiveSync.
Well there are two differences I guess... HardSPL, basically, allows for flashing outside of ActiveSync; and will allow you to flash any ROM as many times as you would like, once HardSPL'd.
As far as the acronym goes, I have NO clue lol. Never bothered to find out, I guess it would be helpful to know .

hardSPL.... will allow you to flash any ROM as many times as you would like, once HardSPL'd.

Technically then.. I could also flash any rom as many times as I want using USPL as long as I run USPL.exe? I read the flashing guide several times. The only difference I found was that you run USPL.exe and it goes through a loader instead of just running the RUU flaser. Is that right?
i apologize once again if I am being incredibly dense.
thanks again for putting up with my n00bness

there ya go! you got it. As you become more experienced you'll start to understand the need of HardSPL.
I was once a noob myself, so i understand where u coming from . Just glad I can help.
Regards,

nkiwan - thank you so much for answering my barrage of n00b questions.
You have been a great help. I really appreciate it.

Wow I think this is the coolest thread I have read ...it is just awesome what the WWW has done for all of us and thanks for the info

Glad I can help

I can understnad the use of USPL but I would recommend the use of hard SPL if you are planning to flash multiple roms. Either way I think it is just a matter of whether or not you actually want to run the USPL everytime you want to flash a rom... Don't quote me on that.

Just to doublecheck myself....
If I use USPL method and hard reset my phone - will I have the stock rom or the flashed one?
if I understand correctly USPL will bring back the stock one after hard reset and HSPL the new one.

very sorry to ask this now..from what i get is there are 3 ways of turning ur phone from phone to super phone:
1. install .cabs
2.soft flashing
3.hard flashing???
am i rite??

Hi Brother,
Same problem with me i have also search every where but failed... no answer about Hard spl.Every body say do hard spl and search in fourm and so on. There was no proper guide what it is and how to do. i was really puzzel. Now i have come to know that axect what it is Hard Spl.
Hard Spl mean CID unlock. If you unlock CId of the phone its mean you have done Hard SPl. Without CID unlock you can not write ROM.
Thanks

I have a T-Mobile Wing. I hardSPL'd it, installed a custom ROM, then I used the RUU to flash the original ROM back to it. It doesn't show the CanonYang startup screen, but the SPL version is still 4.70.Yang. Is it still HardSPL'd?

You can always check in the bootloader screen (the RGB screen).
Even if you have a 4.70.Yang you still need the IPL to be higher than 4 to flash custom ROMs. That is what is important.
If you ever see any of these number's change, Run the HardSPL folder again.

Quick question about HARD SPL

My Kaiser just arrived in the mail, and it came preloaded with DCS 1.7 rom. Since this ROM has already been loaded, I assume the the CID is already unlocked and HARD SPL has already been run once.
So does this mean I don't have to run it again to flash to Dutty's latest rom? Thanks.

not a good assumption, as there are other ways of flashing without hardspl. just put the device in bootloader and see if it says.....something with olipof in it. if that's the case the case then you have hardspl

And if I have HARD SPL, then I just go ahead and flash the Dutty ROM?

Thanks. I read through a lot of that stuff already.
I just checked and HARD SPL is already on the phone. So now it's safe to flash Dutty's rom?

Soounds like you have your answer
Well, it sounds like you've checked so if you're sure, flash away. Although, if you haven't already, I'd do a id10t check first to be doubly sure (i.e. press the camera button+Power button+soft reset) and verify you have Hardspl installed otherwise you run the risk of brickin your phone.

it doesnt hurt to do it again? or am i wrong? its just to be on the safe side

bricked herald ??

hello could anyone help me ?
my device is stuck in bootloader and its recognized by the PC
this happened when i was trying a cooked rom
IPL 1.09.0001
SPL (ditto)
I searche everywhere an there seem to be only ways out for people with SPL 4.00.xxxx
is there a way out ??
thank you

sorry fr the bump but i really need help
I tried placing the phone in bootloader and installing the official HTC rom
but i get an ERROR 300
and the percentage is stuck at 0 on the screen

Try to flash your device with the Stock ROM.
That usually works

He already tried this, but it didnt work.
Let me just quote a post from dougstoner:
dougstoner said:
Well, yes and no. In the long run, it's better to Hard spl your phone. A lot of the roms in the forum require hard spl first. If you somehow fail during the hard spl, then you end up with a "brick". I used the uspl method first to flash, and it was a little easier to do, but hard spl'ing insn't complicated either. You just have to make sure of your ipl number is higher than 4. You can check this by holdign down the camera button, and press the soft reset button (use the stylus on the side to press) and continue to hold the camera button until you get to what's called the bootloader screen. It's red, blue, and green. Here are the instructions for hard spl, but MAKE SURE your ipl number is hight FIRST. If it isn't, you will brick your phone.
I case of people who don´t read 200 post and still brick their device - here is the guide that worked for ALL people with:
HTC P4350
XDA Terra
WING
with IPL 4.xxx and higher!!! (that is IMPORTANT)
and then follow this:
Default
For me it was working when:
1. install canonyang.cab
2. install aserpolicy.cab
3- install disablesecurity.cab
4. SOFTRESET
5. run RUU from Hard-SPLWM6 folder verison 4.70.yang
6. screen will become white - WAIT until it reboots itselfe.
7. done!
check if SPL now is 4.70.yang
Fore sure: I used this
http://rapidshare.de/files/38148213/...l_WM6.rar.html
mirror: http://www.sendspace.com/file/ot8zsn
It worked for many others, too.

So the IPL should at least be 4.xx but as you posted yours is 1.xx?! Might this be the issue?

Unfortunately, a SPL of 1.x after a hardspl/USPL means that the phone has been permanently bricked. Did you try to hardSPL your device or use USPL? They're both only compatible with 4.x SPL's.
I saw that someone recently came up with a way to fix bricked phones. They weren't Heralds, I forgot what they were... They basically found a way to use a buffer overrun on the SPL to launch code so they could launch a patched SPL and reflash... i wonder if our SPL's have that same bug and the method could be applied to us, too.

hey,
if my Herald is IPL 1.xxx can I somehow make it a 4.xxx? Or is there no chance to flash other roms? What does the IPL depend on? Production date?

thanks everyone for your patient replies
I guess for IPL 1.x there seems to be no solution as of now !!!
it was actually working initially with touch IT after Hard spl but i wanted to give a try to another version of touch it thats when the device got bricked .

I feel really sorry for you, but dont give up yet. As ivanmmj said, there could be a solution. Just check the forum.

I am not sure whether it helps but I did a little search and found severals threads:
Fix Bricked HTC ELF/ELFin
Someone with the same ERROR300 as yours
good luck

thanks again xtc.sanchez and everyone else
its been very informative and helpful

Terminology

Hello
Could someone please kindly explain what does SPL mean?
And why ROM is called ROM? Is it the firmware?
Doews HSPL void warranty and USPL not?
I searched at google for a while but didnt get a proper answer.
Sorry to ask this here. Anyway, I am sure there are a lots of people who would like this to know as well.
Thanks

no idea..

Check my post at the end of the "Dummys......" sticky post, Uspl Doesnt invalidadte as its a temporary change as far as I'm aware. Hspl however invalidates the Eula of windows I think.

http://wiki.xda-developers.com/index.php?pagename=HTC_Blackstone

Rom=Read Only Memory in this rom you find the firmware of your device.

thanks for all your replies..
now I understand why these are called ROMs..
but one thing that still haunts my mind..
what does SPL stand for? i am very curious in this..what is it for?
is it some securtiy protocol? or what?
thanks guys..

SPL - second program loader.
the SPL is the bootloader. on a pc, the equivalent is BIOS.
HSPL is what you use to edit the SPL in such a way that it would allow you to use custom ROMS. its a permanent change as you are flashing a new SPL. USPL works only whenever you use/run it, so the SPL remains unchanged. changes are only temporary and when the USPL application is closed (or the device rebooted), the device goes back to its previous SPL.

See the SPL Questions page on the wiki. It will tell you more than your ever want to know .
AFAIK, USPL void's the warranty just as much as Hard SPL, but does it in a way that no-one can detect.
It's like saying the warranty is void if used in the attic, taking your phone in the attic will void it, but it will take some proving that you took it into the attic
Dave

nice example with the attic
thanks guys for your replies...Now I finally now what SPL is thanks to ASK768.. thanks...
have a great one...

no problem.
but actually, while we're at it, why would one want to flash a new radio on their device? what kind of benefits does it give?

I suggest you read up on radio's. Generally speaking newer versions have better reception, GPS fixed, less battery drain. Obviously area/country you are in may effect reception so best to read up on which radio's work better in which areas!

what to do after you downgrade to RC29

I wannna know what is the right thing to do after you downgrade to Rc29 as in
Keeping your phone up to date to instal the latest cyanogenmod
Cuz it seems to me that everytime I do my mods there is always something wrong
Little but wrong ya know I want my phone to run as good as it can .
I'm currently running RC29 US (not rooted no mods at all)
Just waiting to see what's the best thing to do
Thx in advance

What's the difference bewtween hard spl and haykuros special spl somehow I like hykuros better but I don't really know the difference and you think I can use haykuros spl instead of the hard spl while following that guide?

Haykuros SPL repartitions the phone so the System and Data partitions are both ~90mb
The bigger partition allows you to install bigger roms such as Hero
However, the HaykuroSPL has a high chance of bricking your phone permanently if you dont know what your doing....
The most important thing is to flash the 26I radio before the SPL
However, you can install the HardSPL now and install the HaykuroSPL when you feel your read

The death spl is the saphires spl. People load it on the g1's to be able to load a hero rom because the hero roms are bigger needing more space. When you load it on the phone it resizes the partitions to make more space. Thats the reason why you have to flash a rom right after the spl because it overwrites the existing rom. If I were you I would load hard spl first to get the hang of everything then try the danger spl. Many people have bricked there phone due to that spl, but if you do try it don't take any shortcuts and read read read.

What to do,what to do?
Well...I would advise you follow a tutorial or go to youtube and follow a video or video's on how to root and all that happy horsecrap.That's how I did it my first time. I watched videos,watched how others did it and then copied what they did on my phone. I successfully came out of it rooted,with the updated radio,Haykuro's SPL, and a Hero ROM that I could depend on at that time.Since then I have flashed so many different ROM's I can't even count all of them anymore. I would definitely root the phone first though. Possibly call T-MO and ask them for an unlock code for the phone as well as that will let you travel overseas with the phone and use it on other carriers too. Rooting is the way to go with the G1 nowadays. A whole new world opens up to you once the phone is rooted! Anyways...good luck at your beginning and keep up the work. If you end up bricking your phone,call T-MO and tell em one of their updates bricked your phone and you want a new one. Take it slow and do things right though man!
