If not, with this please, but you still won't be able to go to an official.

I got the following error message:
"FOUND SPL V1.20 DOWNLOAD SPL BEFORE V3.03 IS NOT ALLOWD"
The problem with SPL, how to reselove it?

When you first flashed HardSPL, which verson of the SPL was shown after reboot? That, what you had before, or the new one, of the HardSPL? I am asking, because I managed to keep the original O2 2.15 SPL and I really dont want to channge it (for repair reasons
After flashing the patched HardSPL I see 2.G4.4PDA (I have a G4 XDA Neo)! But the good news are that you now can flash all SPL versions you want, like the original 2.15 when it's inside of your ROM image and you can see it after rebooting!

IPL 1.01 upgarde or not?

hi
my rom ver:crc 10.4
spl:2.60
radio: 1.54.30.10
ipl:1.01
i upgarde my rom and radio 2 days ago and evrything is good for now
do you recommand to upgrade my ipl. what is the gain of doing so?
and how do i do it?
If you install Hard SPL ver7 it will upgrade your ipl to 1.04. This will make your SPL 2.10 Olipro instead of 2.60 Olipro. You have the developers Hard SPL installed. It serves no real purpose for the lay person to install this and can create confusion as it throws up an error after flashing a new rom (nothing to worry about). I suppose its up to you if you think its worth downgrading to ver 7 or stick with ver 9. You'll have to live with error messages after flash with ver 9 though...
Cheers....

Downgrading to Original WM5 T-Mobile GER

Hello everyone, just a quick help please!
Bootloader is showing:
HERM300
IPL-1.04
HERM300
SPL-2.10.Olipro
Right now I have WM6 installed.
ROM version: 3.54.255.3
Radio version: 1.48.00.10
ExtROM version: 3.54.255.104
I want to downgrade for the selling purposes to:
HER_TMDE_1211113_1050200_GER_SHIP.exe (WM5)
Do I have to do anything else but just execute the exe and let it install? Could I brick it? (again)
Thanks a lot!

Extact your Official Rom and make a new nbh file with all SPL,IPL,PrimarySplash,SecondarySplash,OS,ExtRom,Radio and use the new Hermes RUU flasher choosing "Force Unsafe SPL"
With this way you will also Downgrade the Olipro SPL and the device will be like it was when you bought it. Exactly like Original.
But remember that there is always 0-1% something goes wrong. I have done this procedure 3 times with no problems at all
It doesn't have to be like when I bought it. It is not a must that I downgrade the bootloader...
Just, is the Olipro 2.10 bootloader going to work with WM5?
For selling purposes, the guy only wants it to have WM5 for some older programs (compatibility issues with WM6). Can I just install WM5 over WM6?
I think it can be done . Make the new nbh file I told you and choose Spl 2.10/2.30 (4th option) and flash
