"Just wait, suddently it continue."
No, it doesnt. Error msg comes out and forces you to it.
SPL can not be easily downgrade by flashing ROM in a G4.

Same problem

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!

How to use Hard SPL if a can't pass bootloader?
I tryed hard SPL, but after upgrading it back to 2.20.001., and I can't pass even to "Windows mobile" screen and it is frozen this position.
Any suggestions?
Thanks

question regarding upgrading

OK im not a new to windows mobile, i have flashed before many times but with wizard.
I want to upgrade my brother hermes,
ipl 1.01
spl 1.06
Im quite familiar with wizards "shelltool" (if you know) which just boots the OS and nothing else.
So can you guide as which tool i should use to just upgrade the OS and leave IPL and SPL and GSM as it is. I think SSPL should do??
Check out THIS MOST AWESOME GUIDE. MrVanx is the best and his guide will give you all you need.
But im in warranty, and i dont wanna lose it by overwriting spl,
Is there any other way to upgrade.
I think SSPL will do but not sure do i need to check for CID also??
Thanks for quick reply.
If your warranty is important, then I would read it very closely.
Probably only upgrades available from your manufacturer or your service provider would be allowed, and in that case you follow their instructions to the letter and if something goes wrong, it's up to them to resolve.
If you go loading WM6 and it's not supported, then you'll be on your own so you might as well load best/safest IPL & HARDSSPL as the experts have so wonderfully published for us lesser experienced people.
If it was my brothers phone, I wouldn't touch it because he'd either hit me or be bugging me for weeks about different versions & software etc, etc, etc
That's just my 2cents anyway.
Good luck! Oggy.

I would suggest not flashing a radio if you don't flash Olipro's HardSPL.
But SSPL will allow you to bypass the CID check for roms, similar to the shelltool for Wizards.
I have learned now to decompile and compile the nbh file.
So i can compile now any rom with OS only and flash it via SSPL.
Can anybody guide me to a guide to use SSPL. OR can u say???
I have one more confusion regarding SSPL that it does change the SPL for time being(for flashing) or for always??
Again if anything goes wrong while flashing the rom(only OS) will i be able to flash the original rom directly with original SPL.

confirming step

I have got the Hermes
ipl:1.01 spl:1.06
I have got the olipro's customruu
I have got the WM6 custel rom.
I only want to flash OS.
Steps:
1. put the customruu and nbh(only OS) in the folder
2. Flash the rom using SSPL option
Coz i dont want to change the SPL version, and i think flashing only OS will not brick my device.
Plz confirm this steps.
AND if ill flash the hardsplv7 will i be able to go back to spl 1.06and how? Please tell.
You can return to SPL 1.06 But i wouldnt recommend it, 1.06 is also known as 'the brick maker'. LOL
Seriously flash HardSPL v7 BEFORE you try ANYTHING else.
mrvanx i have read your guide, its awesome.
But if at all i need it for warranty reasons, can i get it back(IPL and SPL).
Thanks
YES, relax dude.
get flashing
Thanks really appreciate your help.
And to say another thing my company (imate) hasn't released any official ROM for my phone, i have checked the wiki there are roms similar from which i can extract the IPL and SPL and OS which i will need maybe in future.
And i have read that to change the IPL and SPL i need to make a .nbh containing only IPL and SPL and flash it using SSPL option of custom ruu, am I right on this.
Thanks
Yes the procedure is:
Split the .nbh (from an imate ROM...or ANY with IPL and SPL that you want)
into the component .nb files using duttys NBH tool (v1.1 i think).
Then rebuild a new .nbh using ONLY the IPL and SPL bits.
Then flash it with customRUU and (yes correct) select the force SSPL option.
Thank you SOOOOOOOOOOOOO much i think you have helped me alot.
Thanks again, for being so freindly.

I have been there mrvanx guide. but he don't have the solution to this problem. Just to downgrade the rom to wm5 not the SPL.
mysharif i think we have to shout again.
Help us anybody there we are stuck here.
OK guys the SPL downgrade can be done by downgrading to SPL 1.10.oli then flash any ROM with SPL 1.04 in it.
The only reason i can see that you wish to downgrade to 1.04 is because of a warranty issue. What is the problem with your devices??
You are great. I hope it will work for my Imate JasJam. Last night I was flashing my ROM with the original ROM but modified with NBH decomplie too by dutty. Before that I wrecked my device as I used the flashing of ROM using the latest sensation of loading the SSPL to RAM by des. That was my mistake that I used the original ROM. Then I removed the USB cable as it was taking too much time and because of danger to my imate I did that. Anyhow I got the NO GSM error but then I ran the Dutty's WM6v2 cooked ROM and it fixes all the things I am using it now.
The reason for my Imate JasJam degrade is my jog is not working according to its function. You know jumping from field to field. I didn't found any of that problem solution till the page of 30 in threads and posts. I am searching but if anybody knows the link. Kindly help me. So that I will save a trip to see the warranty people. (here we don't have ladies receptionists )
Sorry for the stupid question, how do I downgrade from Oli 2.10 to Oli 1.10
Il write a guide on it...too many PMs about this.

I have the same problem. My touchscreen is dud and Softbank is very anal about the bootloader and warranty. im stuck with Olipro 2.10 and tried flashing the latest softbank rom. When i try via USB/Windows it gives me error 260.
Flashing with MicroSD works, but after a few attempts, its still Olipro bootloader...any ideas?

Ofcourse...because flashing an original RUU it doesnt recognise the new bootloader (Hence your 260 error), and HArdSPL doesnt allow itself to be overwritten by a retail RUU. IF you read through the HArdSPL threads you would know this.

Hmmm, just yesterday (Thursday) I was asked by a VP at our company if that could be done. I was reluctant to say yes, but mrvanx comes thru with a fix.
The VP is in fact worried about having to return some devices to Vodafone, and he want to make them look "original" when they go back.

Just flash SPL 1.10.oli.......................then flash a vodaphone ROM, dont use 'force SSPL', just use autodetect.
well to get spl 1.04 all u have to do is take rom koch and the wm5 rom u are downgrading to. first downgrade os. then take that rom and using rom koch split it into parts and just take the spl and make it into a nbh and use the custom ruu on here. select force sspl and itll make ur spl 1.04. this is a quick guide and do this at own risk. using this method i got my first 8525 to aku 3.5 att and original spl. if marvanx comfirms i didnt make any mistakes i can make a new thread with pics and all so we cna add this to resources and stop the questions.

Or you could just wait until my guide is finished??
You dont need to use the rom koch ... duttys nbh tool is far more appropriate for this since we aint doing any cooking.
yea your right I just wanted to reduce your work load.

Hi mrvanx, some input to go into your guide (in case you havent come across this yet).
While flashing 1.10Oli under Vista, users may run into a problem where after loading SSPL and the phone goes into (SSPL) bootloader mode, the RUU program cannot detect the phone and returns an error.
This is due to the Vista drivers for HTC USB Sync. The driver needs to be manually "updated" just like in your Vista flashing guide. In this case, while the phone is in SSPL bootloader mode, go into device manager, replace the default HTC USB Sync driver with the USBAS one from your Vista flashing guide.
Then soft reset the phone, and try again. Worked for me.
For some reason, SSPL bootloader may appear as a different device to Windows than the hard/standard bootloader, so even if the Vista procedure has been performed before, it looks like it needs to be done also for SSPL.

Hard SPL for Prophet

It's patched SPL 2.20
1. Run SSPL (SoftSPL) - http://forum.xda-developers.com/showthread.php?t=347348
2. Flash HardSPL for your DOC
Yes, really was not hard to patch.. glad it worked))) so, this disables CID and some other checks, so you can flash any custom rom
i have hard SPL/IPL 3.08 will ir work?
newbe here.
What does device root mean?
is it my prophet?
is root windows directory
Looks promissing.
So, as I understand, you don't have to "downgrade" your firmware everytime you want to try a new ROM?
This looks great.
You made our life much easier I think this should be a Sticky
for those of you who dosen't really know what this does.
follow the procedure (soft SPL then hard SPL) and you would never ever need any extra steps before upgrading to wm6.
EDIT: Okay I made it easier. I made a batch file to do the work. (Soft SPL then Hard SPL)
just run the Upgrade_SPL.bat from your PC. It will do the Soft and Hard SPL
Thanks Prislav for this great work
Test to patch a G4 prophet : ok
IPL and SPL version seem differents
IPL : 2.10.00
SPL : 2.G4.4PDA
Test to flash my proper ROM : ok for the moment.
Whaô, WM6 update with progress bar, Fantastic.
Reflexion :
Rom update launched from WindowsMobile synchronised with ActiveSync with patched RUU for Wizard.
My Prophet seems to be reconized by the RUU like a Wizard but upgrade work.
Finally :
Perfect job Prislav it work like a charm, our Prophet are now like other recents HTC devices. It rock : only 10minutes to flash a ROM with special SplashScreen
Now :
Flash just finished, all is ok Prislav, you are the BOSS
Question :
Do a patched RUU for Vista exist ?
Perfect for G4 Prophet... ​
Wooo! Done!
WOW!
I just tried this, and it's amazing! I tried flashing my Original ROM and it worked. Even the SPL was updated. The only thing that it didn't change was IPL. If you broke your phone and have warranty, this is THE easiest way to get the Vendor ROM back. I would even venture to say this is the best tool yet for Flash-a-holics. Thank you so much!
Sounds great, but what about warranty?
Do we lose it if we change hard spl?
worth to try....
This is really an evolution (or is it revolution? ).
lol this removed my spl 3.08,really amazing tool,thanks prislav,big thanks.
IS HardSPL necessary if CID Unlocked ???
I CID unlocked my G4 M600 with the known paid service.
So do i need to HardSPL my phone and why???
Please somebody explain...
as i think,if you have hardspl,you will never be able to brick your phone.correct me if i was wrong.
Can a G4 be bricked? I was under the impression that the G4 was unbrickable. All the bricks I've ever heard of were G3 devices. I mean one can get stuck at bootloader and the like, but I've always got my phone back. Even had a Wizard ROM on there, and even that didn't brick it (although that time I thought it was toast!)! Like zeroed said, it will help you get your SPL back if you have that problem, and I think it's just an amazing tool for flashing in general.

Anyone pleaassseee ?????
I just need to be totally shure about this.. If i run this hard spl thingy patch on my G4 prophet i do not need to downgrade to wm5 everytime i want to try a new wm6 rom, if i currently are using a wm6 rom ?
And how do you guys flash a wm6 rom with the RUU utility ? I haven't seen any WM6 rom yet using RUU..
Just a little confused, sorry!
You wont need upgrading to wm5 - i recommend that you never flash full roms to avoid spl reflashing after hard-spl. the best practice will be to use nb2nbf to generate nbfs for your os, splash and gsm separately
Wait a second. Why should we avoid SPL reflashing after HardSPL??? I already flashed back to my original SPL and re-flashed HardSPL without any problem. What is the danger of doing this?

i wanna change my radio on k-jam g4 howwwww ?

i think we need a radio update or change it but i don't know how cuz i'm g4 and i think it's CID locked ( i appreciate if u tell me how to know locked or not) i updated the rom with soft spl but the radio i don't know what to do my radio now 02.25.11 and i'm having the cannot excute errors what to dooooo helppppp ?
..............................................
i just tried T-Mobile-UK_2.19.11_Radinly and it doesn't start the progress telling me not for u something like that i don't remember
is there is radio official from imate k-jam ?
All of the radio ROMs are official. You just need to download and simply flash one. Since you have a G4, it cannot be CID unlocked, but you can and should apply HardSPL to it so that you can flash more easily than SoftSPL.

i'm already flashing with soft spl i don't know how to flash with hard spl and i'm afraid form it so is there is a way to flash the radio with soft spl for g4 ??????
No. You need to apply HardSPL first, its a simple process. It doesnt "flash" anything really, it just "updates" the Wizards IPL/SPL to a semi-unlocked version...you needint worry, its been tested and has worked for years.

ty for ur support i just didn't want to hard spl for the radio it's a little issue but i'm really gratefull for u thanX
i just hope if there is anything except the hard spl
Nope, without HardSPL it is not possible...why dont you want to HardSPL it anyways?
it's just i liked the soft spl cuz the temporery thing the hard spl u know semi permenant and in the remove hard spl post it doesn't have the imate k-jam spl and ipl so i'm worried a little i thought today about the hard spl and i'm still reading to get it all in my mind to flash any rom (g4 safe) ofcourse with completly fredom that's it by the way my radio 02.25.11 and i want it 2.07.10 my old one or the 2.19.11 this one i want it it's recommended by users i'm very thankfull for u by the way
Well let me ask you this then, are you worried about not being able to remove the HardSPL because of warranty concerns? If so than I understand, but if not, there is really no reason to remove HardSPL after you apply it.

naaaah there is no warranty now i just afraid cuz of returning to an official rom
u know sometimes the update process fails and i need to go back to my wizard love or an official imate k-jam rom and i think that's get hard spl complicated and makes some problems am i right or what??? plz notice me
No, HardSPL makes no difference in flashing the Wizard LOVE or carrier ROMs, it in fact makes it easier...no need to put the device in bootloader mode to do it. I am telling you, HardSPL will make your life much easier as far as the Wizard is concerned.

coool thx for ur help i'll sleep now and in like 8 hours i'll read about the hard spl to do it right thx for ur help alot
i wannted to mention that i think from reading that the soft spl and hard spl is the same but the soft spl every time i flash i have to use and i don't think that it is hard or boring so
tell me experts what will happen to my k-jam g4 if i did this
copy the nk.nbf from the RADIO rom and put it in the soft spl folder like we do in Regular Roms to flash it
the nk.nbf from the rom only has a gsm i checked no spl or ipl or extrom or os or splash nothin just gsm
so what will happen to my runing rom TNT 19209 pro
i wanna know if it will addition the gsm only or it will brick my Wizard
