Difference betweeen SSPL and Hard-SPL

[strikeIII]

Just wondering what would be the difference between these two...which one should i do or do i do both...i read the jumpSPL thread but i'm still not clear on what differences are...is jumpSPL basically bypasses any bootloader whereas the Hard-SPL you have to be at bootloader 1.5...someone pls shead some light...TIA

The way i understand it is that SSPL is loaded onto the phone when running, emulates the original bootloader and then flashes. This means if something goes wrong, you still have your original bootloader to fall back on.

HardSPL overwrites your original bootloader, but once done means the bootloader will always be there to fall back on as it does not allow the rom to overwrite it.

Don't pretend to know the tech stuff, but its nice to have a safety net. If anythings wrong there, please correct :)

yep, SSPL is an old SPL that gets loaded into memory, not stored.

Hard-SPL is one I've hacked up with various features, and I heartily recommend running it on your device.

thanks for the replies...
Olipro if you recommend to Hard-SPL instead then thats all i needed to know...thanks...

but if you load an OEM ROM package, it will overwrite the Hard SPL.

There's a bit of a trick to NOT overwriting it, correct?

Nope... HardSPL will bypass the SPL flashing part of an OEM ROM... as it does with the two published ROMs for the Kaiser/Tilt

SSPL on the other hand doesn't affect the bootloader and will load what is in the ROM, however there is an issue with the Kaiser SSPL at this time. HardSPL is your best bet for flashing.

According to this (http://forum.xda-developers.com/showpost.php?p=1160726&postcount=10) thread:

Can be uninstalled by just reflashing a shipped SPL, so no warranty is lost

And according to this (http://forum.xda-developers.com/showpost.php?p=1164402&postcount=103) thread, you had to extract the .nb files from the ROM and delete the 01_SPL.nb and repackage the whole thing.


So, how do you remove the custom SPL if you want to return it to factory fresh?

ok... Assuming you're starting with a Tilt with HardSPL and the HTC ROM:

1. Reflash the ATT ROM
2. Extract the ATT ROM with NBHextract.exe
3. create a new NBH using htcrt using only the ATT 01_SPL.nb
4. Put your NBH file containing only the SPL into an empty directory on your PC
5. Copy KaiserCustomRUU.exe to that folder
6. Copy the SSPL-KAIS.exe to your phone
7. Run SSPL-KAIS.exe from your phone
8. Flash your "custom" NBH containing only the ATT SPL.nb by running KaiserCustomRUU.exe
9. After it's finished verify your SPL by holding down power and camera buttons while doing a soft reset.
10. Send your phone back to ATT

pretty sure I've covered it all... Let me know your results, I've not actually tried this yet but intend to tomorrow since I have scroll wheel issues.

Good Luck!!

thanks. that actually makes sense. :)

Just tested this process this morning... it works exactly as advertised.

How would this process differ for an 8525 as opposed to a Tilt?

The process is essentially the same but you'll want to use the CustomRUU for the Hermes and obviously you'll be extracting the SPL.nb from Hermes ROMs. The general steps should work fine for Hermes. I believe MrVanx has a very detailed guide on how to do this exact thing on the Hermes, you may want to look that up.
