How to Downgrade Your Wizard (STEP BY STEP) Instruction

[FarSeide]

Hey Guys....

I am still working on this DIY but this is how I was able to accomplish reverting back to my OEM Cingular 8125 state.

If someone could plase let me know how to replace the very first SPLASH Screen from "HTC" to CINGULAR, I would greatly appreciate it.

By following the steps below, you will have almost everything back to its original state.

Be sure to download all the necessary ROM files: OS ROM, Radio ROM, splash.bin
Place your OS ROM and Radio ROM inside the c:\sWizard\ROM folder.


DOWNGRADE YOUR OS AND RADIO ROM
1. Download aWizard 1.3b Beta Version (Attached File or Latest Version) from the following link: http://forum.xda-developers.com/viewtopic.php?t=37386&highlight=awizard
2. Unzip the folder to your root directory (C:\aWizard or D:\aWizard). You need to avoid having spaces your directory name. This is the reason placing folder in the root.
3. Make sure you have an active connection via Active Sync.
4. Run the aWizard.cmd file from C:\aWizard
5. Run "e" command FIRST !
6. Run "u" command. Your Wizard will reboot.
7. Run "w" command to update your ROM. You will get a prompt to choose your ROM. If you did not place a valid ROM inside the ROM folder, then you wont see it from this list. Also, if you placed your aWizard in other directory with spaces (i.e C:\ MY DOCUMENT) then you wont see it either. Just let it run. It will take close to 20 minutes. At the end, it will as you to hard reset.
8. Run "r" command to update your Radio ROM. Same as Step 7.

Replacing Splash Screen (Back to Cingular)
1. Place the splash.bin file inside the c:\aWizard\lib
2. Open up CMD and navigate to c:\aWizard\lib
3. Type in the following command "pdocwrite.exe -n 1 splash.bin 0x002d0000"
pdocwrite.exe = this program is located inside the LIB folder
splash.bin is a file that I converted.
4. Once completed, please reset your Wizard and now you will have Cingular's Splash (2nd Splash)

Updating the EXT ROM
1. I did this manually by utilizing Active Sync to copy over all the Cingular ROMs to the Wizard and running it individually.
2. Reset and you will now have all the programs Wizard came with.


FAQ

Thank you for this.

Don't you have to REINSTALL original Cingular Rom or does this do that by removing imate updated ROM?

When you install Cingular ROM, it will remove/overwrite the existing iMate ROM.

Be sure to place your ROM files in the the ROM folder.

If your running the aku2 imate rom, many people will have problems running awizard or lokiwiz to unlock the CID, I had to run the tmo uk rom update (.exe one) which replaced the imate, and then restore the rom files I had backed up for cingular, although the extended rom is still locked, thats annoying.

FarSeide, I'm pretty sure that even the stock 8125's from Cingular showed the HTC screen first, the cingular screen second, and finally the Windows Mobile screen. If that's the case, then your 8125 is as good as new as far as Cingular is concerned.

Also, if anyone upgraded to the AKU2 I-mate ROM, you cannot do the process you described, because (as someone else mentioned) the lokiwiz program will not work. What you need to do is FIRST install a different ROM using an exe file (a good example would be the leaked AKU2 Q-Tek ROM exe file), and only after that entire upgrade process is completed, can you now use lokiwiz to unlock the SuperCID and install the Cingular ROM.

Eli,

thank you for the info. I wanted to put this together because when I tired to do this, there were information but scattered all over all forums. just wanted to help others so that they dont go through the same thing i did.

i was following these instructions and i got a
NOTIFICATION ERROR
cannot execute repllog.exe

so what i had to do was hard reset, boot screen , re-installed imate, ...
i guess i will try it again, what do you guys think

[Sleuth255]

hmmm... sorry to say but my 8125 only ever showed the cingular splash. No HTC, no WinMob. I had assumed that Cingular somehow replaced all 3 splash screen with theirs.... In fact, I never even knew there was more than one splash screen until I upgraded to the Qtek rom.

I tried to downgrade the ROM and now I'm hung in the i-Mate SPLASH SCREEN. I tried the hard reset and it hangs every time. I can't get a connection through active sync obviously so what are my options. How can I get a working device.

I'm freaking out.

Please HELP!!!!!!!!!!!!!

relax... i was exactly where you were...

first, hard reset your device.
Hold the Com Manager, Voice Command and press the soft reset with your stylus.
before you turn the device back on, hold the camera button then turn on the power. you will receive the boot screen. Plug in your USB Cable and kick off the EXE file. Load one of the known ROMS like the iMate ROM.
reload and try again. I am willing to bet that you disconnected the USB Cable while updating to Cingular ROM.

Good luck and dont worry.

my colleague tried to update his 8125 with my imate rom.....and did not unlock it first.

all he has is the bootloader now, the update gives the well known Error: Invalid Vender ID


Any help is greatly appreciated
Thanks !!

Get a copy of the proper ROM on a SD card, and reload it that way.

This is the easiest way out of that box......

[dirty_harry]

Thanks,

but how to get the Rom reloaded from the SD card onto the device using the bootloader ?

THAT part is easy.

Note that the SD card image is NOT a file. You have to raw write it onto the card, which will destroy the filesystem - so back up the card first! psdwrite will do the job. You also need the image (PREVIOUSLY copied from a SD-made backup with "psdREAD")

To restore it, insert the card, hold the CAMERA button, and power on. The phone will tell you to press VOICE to restore the SD image (it looks to see if there's a valid one in there)

Note that with 1.x bootloaders this will happen with the BACKLIGHT OFF, and you only have 3 seconds or so to press the key - so have a flashlight handy. 2.x bootloaders turn the backlight ON.

Hit VOICE. The image will be verified (checksummed) and if it is good, it will be loaded.

That's it. Takes about 2-3 minutes. When it finishes it will tell you to press any key, and when you do you'll end up at the tricolor screen.

Power off and back on, and the phone will cold boot the new image.

This will work even if you can't run an RUU loader, so long as you can get that first prompt up. It is a VERY effective rescue method.

IMHO before you hack on the firmware in these things you should make an SD card backup just for this reason.

Hi,

Just read your message about writing ROM to Mini SD card.
I'd like to do just that.
I want one or two ROM's for safekeeping stored somewhere instead only a backup or official copy on my pc.
As i've read restoring from SD is safer and faster..
I don't intend to use the SD card for anything more than just that.

In the Prodigy Service Manual (Prodigy Service Manual -XA(0813-2005).pdf) HTC uses mtty.exe. There are also instructions in the PDF.
Since HTC uses this, it should do exactly what i want, i guess?
Or is there a better tool?

Thanks,

Allegro.

P.S: Will a restored ROM from Mini-SD look fresh to HTC?
Or will they see it's a self restored copy instead of a official HTC restore?
Will it reset "everything"?

[FarSeide]

I was able to fully restore CIngular 8125 ROM, EXTROM, All Splash Images using the SD Restore.

100 Cingular OEM Spec has been restored...

[hdubli]

I hv updated T Mo custom ROM..but now can't downgrade even by Awizard utils....can any one throw some light on this?
