I have the same numbers you have, but i dont know what i can and what i cant do...
First of all you must downgrade OS to 7004 which downgrade SPL to ex 1.28. There two methods downgrading:first downgrade SPL by asnar in Mozart Development part of the forum http://forum.xda-developers.com/showthread.php?t=1413694 and the second one via Y-cable. after downgrading SPL to 1.28 you must install HSPL than you will be able to install custom roms. Remember it may be dengerous for your phone if something goes wrong.

Thanks for your answer...
Can you write all passage in order?...this is the first time that I flash a custom rom in my life...I 'm interested at the first method (asnar)...
Help me please
I am trying to build a tutorial for my case, maybe it can be usefull for others!!
All the info was taken from other topics and posts from XDA
Stuff you must know (from DFT thread):
SPL is Secondary Program Loader. It allows to flash ROMs to device.
Without working SPL device is fully bricked, you can’t restore it. It’s why all operations with SPL are dangerous.
OSPL is Original SPL. This SPL comes with stock ROM and doesn’t allow to flash custom stuffs.
RSPL is Reloaded SPL. It load only to RAM, so it doesn’t persistent. It’s enough to soft reset device to get OSPL back.
HSPL is Hard SPL. It’s permanently flashed to internal device memory and replaces OSPL. After soft reset you still have HSPL instead of OSPL.
For regular users, who flash ROMs rather rare, it can be enough to use only RSPL.
For advanced users and ROM makers, it can be useful to install HSPL.
IMPORTANT NOTES
1. Before doing any operations be sure you have battery level more than 50%!
Sometimes in SPL mode WP7F devices DO NOT charge. You may got a cold brick if it power down during SPL or RADIO update!
2. Stock RUU ROMs have two NBH inside, SPL_Signed and RUU_Signed.
So it's not possible directly flash stock ROM, you need extract files and remove SPL_Signed.nbh at least.
3. Rememeber if you have HSPL and you flashing stock RUU_Signed.nbh you lost HSPL!
4. Supported OS: Windows XP, Windows Vista, Windows 7.
Warranty Issues
Be warned, using RSPL may void your warranty.
If you need to send your device to a Repair Centre, make sure that it looks like stock! Install stock official ROM before go to Repair Centre.
My case is:
Htc Mozart T8698
Windows phone 7.5
Os version: 7.10.8773.98
Firmware 2250.21.51201.401
Firmware 0004
Radio 5.71.09.02a_22.51.50.21U
Radio A.102.0.D4
Boot loader 5.12.2250.1(134578)
SOC 2.2.5.0
What i want to do? FULL UNLOCK IT!
So what i have done...
First of all you must know your Mozart!!
The important numbers, in my case, where:
Os version: 7.10.8773.98 because you must downgrade from 8773 (my case) to 7004
Firmware 2250.21.51201.401 THIS TUTORIAL IS FOR THE ONES THAT END IN 401 ( its called the CHARACTERISTIC VALUE and its CV401)
YOU SHOULD READ more info in this thread from ansar: http://forum.xda-developers.com/showthread.php?t=999405
Boot loader 5.12.2250.1(134578) BECAUSE YOU WANT YOUR BOOTLOADER TO BE IN VERSION 1.28.2250.4
Now you know your numbers I MUST SAY! If your Mozart ends in 401 (CV 401) you can continue, if not this tutorial is not for you!! Sorry, but keep looking!
FIRST STEP!
You shall want to downgrade your rom to 7004 which will also downgrade your SPL to 1.28!! SPL IS THE SAME HAS THE BOOTLOADER!!
You can do it by 2 ways!! Using the cable method (will not do it) or via the asnar method ( THATS IT!! TANX ASNAR)!!
So lets do it with the asnar method which is on this thread:
http://forum.xda-developers.com/showthread.php?t=1413694
READ IT ALL A FEW TIMES!!!
i will not tell how to do it because the asnar thread is obvious, and i advise you to read it a few times!!
I WILL THIS: if during the downgrade process you got the ERROR 270 its because the SPL is version 1.28.2250.3 dont worry it happens to me, i know you are stuck now and the mobile doesnt do nothing instead of showing the bootloader screen!! What you will do now is upgrade the SPL to 1.28.2250.4 ok??
dont worry! just install this one on this thread: http://forum.xda-developers.com/showthread.php?t=858599
So after that you on the correct 1.28, lets keep going...
SECOND STEP
You must want RSPL and then HSPL
so just read this a few times, but its all on the first page:
http://forum.xda-developers.com/showthread.php?t=1195647
If all its ok, now you can add any custom ROM like NextGen, Dynamics, DeepShinninh of NewTech from asnar!!
Thanks majkellj!!

I will soon have a Cingular 8525. I was thinking of upgrading it to the South African ROM. The one with the 1.09 bootloader.
I know the phone will have either a 1.04 or 1.06 bootloader so I can definitely unlock it, but I am looking for a full procedure thing. There is a lot with this, such as not being able to downgrade from 1.09 to 1.04 (which I found out you can actually do), and getting the SuperCID working, etc.
So could somebody be so kind and write up a procedure so I dont screw up a brand new phone. Thanks a bunch.
I second this request.
Actually I have read quite a lot about this on these wonderful forums by wonderful people but I am still not confident and therefore want to ask some specific questions:
1) My Jasjam original ROM is with bootloader 1.06. On the I-Mate site there is a ROM available with bootloader 1.04 and having the same CID as the one currently on my machine. If I install this ROM will my bootloader change to 1.04 from 1.06??
2) If after installing the ROM with bootloader 1.04 I attempt to install any other Hermes ROM say the Dopod ROM will it be possible simply by connecting my device with the computer through active sync and running the installation file on the PC?? Personally I think this will be possible as the bug in the bootloader 1.04 will allow me to do so.
3) My last question is that if after installing the i-mate ROM with bootloader 1.04 I install another ROM with bootloader 1.09 will I be permanently stuck with the bootloader 1.09 and afterwards not being able to install any other ROM.
I know some of my questions may sound foolish but I need the answers to gain some confidence that I have understood what I have read in these forums.
Kind Regards
@staulkor:
- Downgrade to cingular 1.30 rom to have bootloader 1.04 on your 8525
- Follow unlocking process as explained in the Readme file
- Double check that your radio version has changed from 1.13 to 1.16 after flashing the patched radio, once you're running the patched radio run Herm_Unlock_v2a.exe to SIM/CID unlock your phone.
- Upgrade to cingular 1.34 ROM again if you want the original ROM back on your device
@srmz:
1. yes
2. yes
3. yes, but read this
Thank Pof. I have heard much about you and all of your greatness throughout these forums. Thanks again
Dear All,
Could someone please tell me how to get the SPL back to original. Im planning to sell the phone and it basically needs to be completely as it were.
Thanks a million!
Kind Regards,
Henry

Thanks to Walshieau, Todd_jg and Olipro for helping me out with this.
This guide will take you through downgrading the Bootloader (SPL) on your Hermes device
This guide assumes you already have flashed ROMs and Other components and you are familiar with the process.
NOTE: By downgrading your SPL version your device is more vulnerable to being permenantly bricked if a flash goes wrong, by following this guide through YOU accept responsibility for any problems faced due to this operation. As with other downgrade guides this is NOT intended as a guide for claiming the warranty of the device having flashed components which are not authorised by the manufacturer or carrier.
The downgrade will take the following steps, since HardSPL does not allow itself to be downgraded directly, nor does SSPL allow versions lower than 1.09 to be flashed.
The first step is to dowgrade to SPLversion 1.10.oli. Firstly download this archive and extract the files to a temporary folder, connect your device up via the USB port and allow it to connect to activesync. Run "RUUWrapper.exe" which will fire up the RUU program:
Select 'Force SSPL' and continue the flashing process as usual.
Allow the flashing process to take place and your device will reboot.
Now check the SPL has been changed by entering bootloader mode, press and hold the side ok and power buttons then insert the stylus into the hole in the bottom of the device. Your SPL version should now read "1.10.oli".
The next step is to download the SPL you wish to finally downgrade to:
SPL 1.04 (includes IPL 1.00)
SPL 1.06 (includes IPL 1.01)
Again extract the contents to a temporary folder and connect your device to activesync via USB. Run "RUUWrapper" in this new folder.
Select the RED OPTION, and TICK THE BOX.
Then flash as normal.
This will flash the final SPL version onto your device.
Verify your SPL version once this has completed by allowing the device to boot into windows Mobile and entering the bootloader as before.

Shouldn't need to access OS. You should be able to do it by putting it in BL mode... THEN plug it into the usb. Then start the updater.
Its 2.30.Olipro I need to downgrade from, and you cant overwrite olipro SPL's without using SSPL by des from inside the OS, I'm trying to find another way

2.3 is similar to 2.1.
As MrVanx's guide points out, the key is to get from 2.1 down to Oli 1.1. That will work. His guide works - guarantee it.

Thanks for the help, but MrVanx's guide uses SSPL by des (launched from inside the OS where I can't get to) to overwrite the 2.10.Olipro to get back to 1.10.Olipro, so that method wont work for me either

Oh interesting. A nuance I hadn't picked up on. So, when using the Force using SSPL" option in the flashing utility, you must be able to access the Phone OS? That surprises me, I thought that the RUU utility would put it on the phone even in BL mode and execute it? Hmm... strange. I guess if it is an exe, it needs the OS to run, though. Sort of makes sense. Sorry about the misdirection.

Hi,
I'm trying to downgrade to the original SPL (I'm trying to get hold of 2.03 but can't seem to find it), so am using 1.06. I've been able to downgrade to Oli1.10 from Oli2.10, but it won't go back to 1.06 from there, after the RUU says successfully completed the SPL is still the same.
Any ideas?
Cheers
downgrade phone for rogers warranty
Hi Guys,
I need to downgrade my phone as well for warranty purposes. Unfortunately Mrvanx's guide is offline at present. Can any one of you give little further detail about what I need to get back to orginal rom/radio/spl and bootloader. Or in shor to be able to send it back for warranty. I do have a new Rogers phone if that can be of any help.
It is from Rogers and currently my boot loader screen says following:
HERM200
IPL-1.04
HERM200
SPL-2.10.Olipro
Under Device Information:
ROM version: FARIA.R-32
ROM date: 11/06/07
Radio version 1.54.07.00
Protocol Version 32.86u.7020.23H
ExtROM version: BIGSTORAGE
My replacement Rogers Phone has following:
HERM200
IPL-1.01
HERM200
SPL-1.11
Under Device Information:
ROM version: 1.34.631.14
ROM date: 04/17/07
Radio version 1.42.00.00
Protocol Version 32.75.7020.18H
Can anyone please tell me if it is even possible to do this downgrade.
Thanks
B.
why dont you just brick the phone if you are worried about them complaining over the boot loader version. If you cant access the phone i doubt they will be able (or even be bothered) to
Could you please let me know what you did? Did you downgrade To the original Rogers Radio and SPL ? Do you by any chance have all the original Rogers files (WM5, SPL, Radio,...)?
I am with Rogers too and just unlocked SIM (not CID) and installed WM6 (official HTC)
I am wondering how I could lock SIM again if I need to return the phone for Rogers warranty? or unlocking SIM does NOT void the Rogers warranty?
Thanks
Downgrade to SPL 1.11
Hi is anyone able to figure out how to downgrade from SPL 2.10 Olipro to SPL 1.11? I have tried Mr Vanx guide but at the end of the process, I get Error 260. Not sure if I am doing anything wrong.
Do I have to downgrade to SPL1.10 Olipro, before I downgrade to SPL 1.11?
Thanks
I am having some issues downgrading back to an original SPL. I've searched throughout the site and have found a lot of conflicting advice, although this thread seems to be the most relevant.
I started out the process with SPL: 2.10.Olipro
I downgraded to 1.10.oli.
This process was successful in that the bootloader screen now says that the SPL version is 1.10.oli.
Now, when I try to flash the OEM version of SPL, the phone asks the following question:
You would like to run jumpspl.exe
If I say yes, the screen goes gray and says load... but I end up with a 260 error.
I have tried turning off the usb connection in the active sync and starting from the bootloader as mentioned here, but that just ends up giving me a 264 error.
Any suggestions would be appreciated.
Cheers,
~Hat

Post #5 from here fixed the issue.

Okay, Im back to 1.10oli, but how do I know if I need to go back to SPL 1.04 (includes IPL 1.00) or SPL 1.06 (includes IPL 1.01)?
OK people, please tell me you have looked at the updated guide right??
http://www.mrvanx.org/thg/index.php?option=com_content&task=view&id=19&Itemid=27
Yes, but the choices are,
1.04
1.06
1.09
1.11
2.03
and I don't know how to tell which one is stock for my phone. I assume I need 1.04 since my bootloader says IPL-1.00 but I'm not sure because I know that used to say IPL-1.04, and since it appears that that can change for some reason, I want to make sure I get this right so I can get this waranteed. Im going to sell it on ebay and get the new HTC Fuze as soon as AT&T releases it.
Hi
I Just purchased sp locked JASJAM with WM5
I'd like to upgrade to WM6.1
I've read allot at the forum, (also got disappointed about the GPS thread)
I've learned allot, and I Thank you all for that.
Before I upgrade I Have few questions, Which I didn't found answers so far.
Since It is still under warranty, how can I Backup the original Radio, Rom, Etc..
So in case of warranty issue, I"ll be able to restore to the original provided package ?
Will I Be able to sp lock it again ?
Does anyone need my original ROM provided by Cellcom (ISRAEL)?
ROM VERSION: 1.31.305.2
ROM DATE: 09/08/06 (sounds old to me)
Radio Version: 1.21.31.10
Protocol Version: 32.53.720.01H
ExtROM Version: 1.31.305.243
Thank you all for that great forum

1). check the wiki for your original rom and radio rom. good to have a copy of these on your computer in case you need to revert back(your rom may have been updated by your carrier, I'd contact them and see).
2). Check you IPL and SPL version by going into bootloder screen (you can find out how by a quick search) then look on the wiki for how to downgrade SPL to stock SPL. download all versions of Spl you need as I find it convenient to have this stuff if something goes wrong and you cant get from the site.
3). Make sure you unlock & Hard SPL you hermes before ANYTHING else... Putting Hard SPL on DOESN'T mean it WON'T brick, it just means its EASIER to unbrick if something does, and probably will if you flash a lot, goes wrong...
May I suggest you Hard SPl your phone then use the sd card method (my personal favourite method) to flash as there is less chance of ANYTHING going wrong as long as it has more than 50% battery power...
Happy Flashing and I hope not to see any posts about needing help unbricking.... Cheers
how to enable KITL ?
I have keep reading the tutorials and troubleshoot (how to unbrick) ...
I Have noticed that I dont have KITL enable (or available), which very important for recovery.
I Have:
SPL: 1.06
IPL: 1.01
Kinda old I Think...
is KITL a software in bootloader ?
Will I Be able to enable KITL if upgrading to the latest SPL ?
(Or in other words, How can I Enable KITL to minimize risks?)
Flash Hard SPL after unlocking the phone. This makes your phone able to flash ANY HERMES rom.... This WONT STOP BRICKING BUT WILL MAKE IT EASIER TO RECOVER IF (AND WHEN) THINGS GO WRONG...It is not a guarantee BUT it is a safety net that helps out. Cheers...
Hi Guys,
I need to downgrade my phone for warranty purposes. Can any one of you give little further detail about what I need to get back to orginal rom/radio/spl and bootloader. Or in short to be able to send it back for warranty as for some reason my phone keeps dropping the GSM signal(tried flashing GSM-Radio and OS roms but no luck).
Following specs worked great for almost 6-8 months and now keep dropping signals
These were the specs from current ATT 8525 (HERM100)
AT&T 8525 (Hermes 100)
ROM: vp3G's WM6 v3.60 "Full" + Add-Ons
Radio: 1.54.07.00
IPL: 1.04 | SPL: 2.10.Olipro
I have already flashed OS and GSM ROM back to the latest ATT ROM from this link (http://www.htc.com/us/SupportDownload.aspx?p_id=65&cat=2&dl_id=67). So current specs under device information are
AT&T 8525 (Hermes 100)
ROM: 3.62.502.3
Radio: 1.54.07.00 (This is not showing as currently there are no signals on phone)
IPL: 1.04 | SPL: 2.10.Olipro
Or do you think I should flash the device to the original ATT ROM (factory installed) from this link (http://www.htcamerica.net/support/8525/software-downloads.html).
Once this is done, I wish to rollback SPL and Bootloader back to factory settings. I am not sure the original version of the spl and bootloader. So if you think it's anyhow possible, can you guide me through the instructions?
I have 10 days before I return my current device with replacement unit.
Thanks in advance

Downgrading SPL and ROM
Hi here are the steps you will need to perform if you have Hard SPL v7 installed on your phone. (How do you know if you have Hard SPL or not? Just go into bootloader and if you see SPL 2.10 Olipro, you have Hard SPL.)
Next you will need to downgrade to Hard SPL 1.10 Olipro. You can find it here Hard-SPL. This is very important as this will allow you to downgrade your SPL.
Once this is done verify the SPL version in bootloader. It should be SPL 1.10 Olipro.
Now flash the manufacture specific ROM. This will take the device back to factory settings. It will also take care of the IPL and SPL versions.
Hope this will help you.

FIRST STEP!
You shall want to downgrade your rom to 7004 which will also downgrade your SPL to 1.28!! SPL IS THE SAME HAS THE BOOTLOADER!!
You can do it by 2 ways!! Using the cable method (will not do it) or via the asnar method ( THATS IT!! TANX ASNAR)!!
So lets do it with the asnar method which is on this thread:
http://forum.xda-developers.com/showthread.php?t=1413694
READ IT ALL A FEW TIMES!!!
i will not tell how to do it because the asnar thread is obvious, and i advise you to read it a few times!!
I WILL THIS: if during the downgrade process you got the ERROR 270 its because the SPL is version 1.28.2250.3 dont worry it happens to me, i know you are stuck now and the mobile doesnt do nothing instead of showing the bootloader screen!! What you will do now is upgrade the SPL to 1.28.2250.4 ok??
dont worry! just install this one on this thread: http://forum.xda-developers.com/showthread.php?t=858599
So after that you on the correct 1.28, lets keep going...
SECOND STEP
You must want RSPL and then HSPL
so just read this a few times, but its all on the first page:

If all its ok, now you can add any custom ROM like NextGen, Dynamics, DeepShinninh of NewTech from asnar!!

I see some people with problems and doubts when its time to install a custom rom. I was one of them, so now that i've installed a custom rom, its time to share the procedure i've taken!
I am trying to build a tutorial for my case, maybe it can be usefull for others!!
All the info was taken from other topics and posts from XDA
Stuff you must know (from DFT thread):
SPL is Secondary Program Loader. It allows to flash ROMs to device.
Without working SPL device is fully bricked, you can’t restore it. It’s why all operations with SPL are dangerous.
OSPL is Original SPL. This SPL comes with stock ROM and doesn’t allow to flash custom stuffs.
RSPL is Reloaded SPL. It load only to RAM, so it doesn’t persistent. It’s enough to soft reset device to get OSPL back.
HSPL is Hard SPL. It’s permanently flashed to internal device memory and replaces OSPL. After soft reset you still have HSPL instead of OSPL.
For regular users, who flash ROMs rather rare, it can be enough to use only RSPL.
For advanced users and ROM makers, it can be useful to install HSPL.
IMPORTANT NOTES
1. Before doing any operations be sure you have battery level more than 50%!
Sometimes in SPL mode WP7F devices DO NOT charge. You may got a cold brick if it power down during SPL or RADIO update!
2. Stock RUU ROMs have two NBH inside, SPL_Signed and RUU_Signed.
So it's not possible directly flash stock ROM, you need extract files and remove SPL_Signed.nbh at least.
3. Rememeber if you have HSPL and you flashing stock RUU_Signed.nbh you lost HSPL!
4. Supported OS: Windows XP, Windows Vista, Windows 7.
Warranty Issues
Be warned, using RSPL may void your warranty.
If you need to send your device to a Repair Centre, make sure that it looks like stock! Install stock official ROM before go to Repair Centre.
My case is:
Htc Mozart T8698
Windows phone 7.5
Os version: 7.10.8773.98
Firmware 2250.21.51201.401
Firmware 0004
Radio 5.71.09.02a_22.51.50.21U
Radio A.102.0.D4
Boot loader 5.12.2250.1(134578)
SOC 2.2.5.0
What i want to do? FULL UNLOCK IT!
So what i have done...
First of all you must know your Mozart!!
The important numbers, in my case, where:
Os version: 7.10.8773.98 because you must downgrade from 8773 (my case) to 7004
Firmware 2250.21.51201.401 THIS TUTORIAL IS FOR THE ONES THAT END IN 401 ( its called the CHARACTERISTIC VALUE and its CV401)
YOU SHOULD READ more info in this thread from ansar: http://forum.xda-developers.com/showthread.php?t=999405
Boot loader 5.12.2250.1(134578) BECAUSE YOU WANT YOUR BOOTLOADER TO BE IN VERSION 1.28.2250.4
Now you know your numbers I MUST SAY! If your Mozart ends in 401 (CV 401) you can continue, if not this tutorial is not for you!! Sorry, but keep looking!

Hi all,
Portuguese Operator Optimus HTC blocked to them. I followed this tutorial and so far i have downgrade to SP 1.28 but i had the issue error 270 so i had to downgrade two times for .03 and for the .04 SPL version 1.28 .
After that did the HPSL i had some problem decidyng wich version to decide, but i see that my spl is 1.28 it version 1 of the HPSL, did all went ok.
Now i will try the rom at 7.8 and one from the http://forum.xda-developers.com/showthread.php?t=1239474&page=11 to try to correct the issue of screen not respondig at first.
Just a thing i tried the Mwang at http://forum.xda-developers.com/showthread.php?t=1239474&page=11 to solve the screen issue and it solved because of the downgrade of the screen driver to should stay at v63.
now let's go to a 7.8 rom and restore my full zune backup.
I tried the nokia 1.2 at 7.8 version maybe because i always had nokia phones since 1997, and now doing a full restore of a zune backup in 7.5 version.....
Almost, rebooting and ... restoring ....
