Downgradeing HTC Wizard

Hi,
I've installed the latest AKU 3.2 Version on my Wizard.
Now i've wanted to downgrade to AKU 2.0 (with the original Loader Provided from "Vario_AKU2.0_05-2006.exe") and the tool tells me it is not possible. Is there a way to make it run?
Thanks a lot

It looks like nobody has an idea how to downgrade from SPL2.xx en that sucks! noboby warns about it when supplying new ROMS..
I have the same problem with a TMobile Vario that needs to be flashed to stock ROM\IPL\SPL..
I've found a way to do it but its for the HTC Thyfoon and might not work with the Wizard..

Nobody warns ??????????????????????????
Gramma told me that if I don't have something nice to say to keep quiet...
Maybe if you downgrade to a 1.xx ROM first you can then go back to your AKU 2.

There are tons of threads on this issue already... maybe if you are hardworking enough to search for it yourself, you won't even have that problem at all... warnings are placed everywhere... please read before you even proceed to upgrade your rom...

I've searched for hours the two solutions Boots 1.05 end Cingular 1.8 do not work but if you are so sure their is an solution ill keep searching
Ofcource I know about warnings but ive NEVER seen an warning about SPL not being able to downgrade..

Possible solution
A German mate told me that there is a solution
Try to load the Qtec Custom Rom from ...
http://wiki.xda-developers.com/index.php?pagename=Wizard_Upgrades
.. and Flash it to your Wizard. After that is should be possible to load older Roms without any problems.
I did not have tested it... (Please tell me if its works or not).

If you have a G3 device you can downgrade your IPL/SPL. I've done it my Cingular 8125 and it's 3 replacement PDA's numerous times. In addition I've downgraded at least 20 phones to 1.05 so's I could unlock and then upgrade. And then done it again. If you follow faria's instructions that is.... Now I HAVE had to flash the 1.05 twice to get the SPL down to 1.05. Humor us huh?
Note: I realize that Faria says that it doesn't work above 2.21 but I have performed this procedure on at least a dozen "out of the box" Cingular 2.25's. Downgrade to 1.05. Extract lokiwiz to the root of your C drive. Copy enablerapi.cab to your device (I know that you've unlocked your device, just indulge me please ) Execute enablerapi.cab from your PDA. get to a Dos prompt and run lokiwiz from the C prompt. Unlock CID and SIM. It WILL reboot each time. If your IPL / SPL still show a 2.x reflash again with the 1.05.
If you do this I'll just about guarantee that it'll work
Good Luck!

Your garantee worked great fabulous work ! I downgraded my Dutch MDA Vario from official Tmobile Rom RUU_Prodigy_2210205_22102108_021911_TMO_NL_DUT_Ship.exe with 2.21 IPL.SPL to 1.05. Indeed needed to run WWE flashrom - did the Lockwiz2b CID unlock and ran the Flashrom WWE again and voila IPL/SPL 1.01 - OS 1.5.4.2 -GSM 1.12.10.0 - Thanks a lot!!
I owe you one ..

Hi,
i want to downgrade my 2.21 G3 Vario as well which is NLD and locked. I believe that I know all the steps neccesary and already downed the QTEK custom ROM. Can I just execute this ROM and have it install the older version on my Vario, run lokiwiz02b and upgrade again?
One part I didn't find on the forum was the need to run "WWE flashrom" again to downgrade to 1.05
What is this WWE flashrom, is it a seperate tool besides the Custom rom and if yes where do I get it?
thanks,
stefan

Does NOT work, thnx anyway

I have the same problem.
But i allready downgaded with the Custom version.
When i restart i can see. it is IPL 1.01 and SPL 2.26
Is it possilble olso downgrade the SPL (i do not exactrly know what it is)

Downgrading/Upgrading
Dr P. or anyone else,
I've seen "somewhere on this board" a description of how to flash "any rom" without having to downgrade to 1.05, it stated to change the .exe file to a .rar and then change the ruu file to one that is not looking for the current phone status. I've tried that and have not had success in doing so. IF there is infact a way to do this, could someone please provide a blow by blow scenario to accomplish it?
Thanks,
vpu2

Bet you didn't run the 1.05 a second time as I stated before. I'm actually doing a brand new Cingular G3 2.25 as we speak. I downgraded to 1.05, SPL still says 2.25. Copied enablerapi to the device and executed it from the device. Extracted lokiwiz to the root of my E drive (on my new thinkpad that I'm setting up at the same time...) It rebooted twice as it's susposed to when you unlock the CID and the SIM. Ran the downgrade a second time and both IPL and SPL are 1.01, the GSM is 1.12.10.0 and the OS is 1.5.4.2.... every freak'n time I do this, probably close to two dozen Cingular 8125's. If it don't work for you I just don't know what more to tell ya....

I tried everything what everybody said in this post.

Mr hokkie, please humble me and document exactly what device you own and your exact IPL/SPL/OS/GSM versions. Beacuase I just don't think that you've got in in ya to be my first failure. Show me what you got

I own a Dutch MDA Vario from T-mobile, which has a T-mobile SIM-lock. I want to remove the SIM-lock, so I tried http://forum.xda-developers.com/showthread.php?t=249474&page=1. Unfortunately it returned an error, it appears I have a 2.21 ROM, so I want to downgrade the rom, which brought me to this thread.
I've downloaded the CUSTOM_RUU_Wizard_1050412_WWE_101_11210_WWE.exe, and ran it. I get the first few screens (the caution-screen, the prepare-screen, the Update screen, the verify screen and the last screen). After that I get the screen where a percentage bar should start moving. My phone-screen is now divided in about four horizontal parts.
The first one is red-fading to black, and it reads RUU on the top-right, and the line below it reads IPL 2.21.0001. The last line in this part reads SPL 2.21.0001.
The second part is similar to the first, but it is green, without any text. The third part is similar to the green one, except it's blue.
The last part is smaller than the previous parts, it's plain white (about two lines high) and reads USB.
On my PC I get a screen telling me:
ERROR[300]: INVALID UPDATE TOOL
This Udate Uility cannot be used for your PDA Phone. Please get newer Update Utillity.
What am I doing wrong here? (BTW: I'm a computer-expert and a phone-noob)
By the way, the verify screen reads:
From:
Model ID: WIZARD
Image Version: 1.2.0.0
Language: ENGLISH
To:
Model ID: Prodigy
Image version:
Language: WWE

Got myself in a bind

Even though my 8125 was running just fine on a Molski ROM I got months ago, I had to go fiddle with it and see what kind of damage I could do. Now, I have myself stuck at IPL 1.01, SPL 2.26, GSM 01.12.10 and can't seem to find a way to get my IPL back to the 2.xx range. Since there are no longer any ROMs posted here, I am afraid to try some of the ones I am finding elsewhere since I don't know if I will turn my Wizard into a paper weight.
Does anyone know what ROM would be the best to use to give me a newer NBF so I can just put the current factory ROM on? I had read that the MrClean_RUU_WIZARD_224a_AKU23_WWE would be the right one, but I can't find it anywhere now.

Run the T-mobile 2.26 rom which you should be able to get from tmobiles site. that will get you to ipl and spl 2.26

Appreciate the thought, but the T-Mobile site requests that I enter my phone number, which is not a T-mobile number, but a Cingular number.

Then grab the rom from Cingular's site. I believe it will get you to IPL/SPL 2.25.
Any AKU2 carrier rom will help you (assuming you are CID unlocked since you previously had Molski's rom installed) In any case if you are a cingular customer and got your phone through them normally even if it is CID locked it is locked to Cingular and you can flash their rom.

That's the whole base of the problem here, as I said in the first post my IPL is only 1.01, so trying to install the Cingular ROM gives me the infamous "Please get a newer NBF file" error. I've tried everything I can to take care of the problem, but the needed ROMs to work back up to where I need to be are all gone.

Wizard Love and the Button ROMs are both available on PirateBay. Use the Button to do a CID Unlock again, or use Wizard Love to try to just recover.
As for the T-Mobile site, if you use the link in the sticky for how to CID Unlock by Dr. P, that one does not ask for a phone number. Takes you directly to the place where you do the download (I just downloaded it again yesterday and can email it to you if you need it (PM me with your email)).

Sorry, I didn't get out of your first post that you had tried the offical Cingular ROM just that you wanted to end up on it. Read through the G3 unlocking sticky. The button 1.05 rom should do the trick. I think the link in there is working though it may be a slow download. I no longer have any wizard roms on my system or I would host it so you could grab it real quick.

I haven't done this before (so take it for what its worth) but you could pull the Cingular RUU file apart with WinRAR, and get the nk.nbf file out of it and run that with a Rom Update Utility NOID (that comes with most of the custom ROMs) and that should allow you to flash it no matter what the IPL/SPL are at as I understand it. (so you shouldn't get the need newer message).

Okay, download the button ROM and the T-Mobile ROM now as well as printing out the unlocking guide. I know I've done this before, but it was a long time ago.
Thanks for the help guys!!!
---EDIT---
You know what, just reading the ENTIRE FRIGGEN INSTRUCTIONS solved the problem. One little line towards the end of Doc's instructions ... "A last note. If you DO ever go back to the 1.05 ROM for any reason you need to repeat the lokiwiz steps as you won't be able to install a 2.x IPL/SPL bootloader."
That's it, one little line on the last page that I just skimmed over and that's all it was in the end.

Some help please

I am pulling my hair out here...
I have an 8125, with the following
Sim Carrier and Rom = T-Mobile
IPL/SPL=3.08
GSM=01.12.10
OS=1.5.4.2
Rom Version=1.5.4.2 WWE
Radio Version 01.12.10
I followed the two main tutorials on how to SIM and CID unlock, got both my IPL and SPL to match, flashed in the TMo Rom and thought all was good.
Now I was poking around and see that it is not a 2.26 rom that is on there but it is a 1.5.4.2. So what do I do, I go to
http://www.t-mobile.com/wmupgrade/
to get the Mobile MDA Software Version (2.26.10.2)
and when I run the file that gets downloaded, it gives me a
ERROR [296] : UPGRADE ONLY
Now, does it see that the phone is infact not an MDA and is a 8125 and does not like it?
So now from this point, (I have done my research and forum search, and RTFM many times so pleae dont blast me) what do I need to do to get the updated 2.26 rom, and eventually get up to the WM6.
I appreciate all the help, as I am seriously ready to have phone meet wall.

You have already flashed newer bootloaders that 2.26. You have 3.08. Why do you need to go back to 2.26? IF you are CID unlocked (did you take your bootloaders down to 1.xx then run lokiwiz, and then bring them up to 3.08?) you should be able to flash your WM6 rom now. Have you tried?

I think he upgraded the IPL/SPL alone from button's 1.01 and now can't flash any ROM since 3.08 can't handle 1.5 OS.
My advise is to flash IPL/SPL 1.01 and from there flash a 2.26 but... there are a lot of people mentioning IPL 3.08 and SPL 1.xx meaning that IPL won't allow to downgrade. I think it's up to him...

my understanding is that you shouldn't be going to an ipl/spl of 3.xx unless you are flashing from an ipl/spl of 2.xx. (based on thread information from old roms of molski and faria, last days of wm5 roms).
if possible, you should try to reflash back to 1.05 (i think they were customized so you shouldn't have problems).
official t-mobile roms won't let you downgrade to my understanding...at least not from one official t-mobile to another official (3.08 --> 2.26 or 2.26 -->1.80).
so...retry to flash buttons 1.05, then move up to 2.26...and then if you really want to flash again to 3.08.

That is exactly what I figured out last night.
When I RTFM where it says EDIT STEP 17: Flash to 3.08 .......
I took that as a instad of thinking that it contained the 2.16 rom as well as the IPL/SPL upgrades.
So I went through reflashed both back down to buttons 1.05 and then reflashed back up to 2.26 and then to WM6, everything is dandy and it is all becuase of the wonderful people here. I can not say it enough. This place is the greatest! And thank you all yet again.

I'm glad you managed to save your phone. Not many these days by counting the number of "Help" threads
Can i ask you to please give something back to the forum? please check my signature and visit the "Data crashes" solution thread. Tx

Definitly will.

Help. Ive got a Brick !!

Can anyone please help with my brick ? ? ?
I tried to go to WM6 by unlocking the CID and the phone - so far so good. Read that i needed IPL/SPL 2.xx or higher so set off to search. Found IPL/SPL 3.08 so installed those to my phone. Then tried to upgrade to the WM6 official rom found on these very pages. Now every time i flash i get update error 302 at 99%.
Im almost sure its the IPL/SPL but i have nothing to backtrack to and not a lot to back this theory up as im still a newbie in the ROM area. My original versions were 1.02 each as i have a G3 O2 XDA Mini ( wizard )
im really stumped and phoneless at mo so ANY help would be grateful for.
Thanks
Andy

I bet you went from 1.02 to 3.08 without stopping at 2.xx
Maybe that's the cause?

but he says than he flashed with the oficcial rom there is no oficcial are agree

Hi Guys,
Thanks for the quick replies.. I used
http://forum.xda-developers.com/showthread.php?t=310954
( about quarter way down it says official download site for WM6.0.0)
Mestrini - Yes i went straight from 1.02 to 3.08 coz i cannot find the V2.xx IPL/SPL files but i have found the updater solely for the IPL/SPL to 3.08 which is what i used.
is that any use ??

flash your phone with the tmobile 2.26, that should correct your issue. It will also give you the 2.26 version of spl/ipl

ok if you had a cid unlocked device search in the forum for the t-mo 2.26 ipl/spl after you can update for the rom as you tell
en joy it

Thanks for the advice guys, ive tried several different roms and i have a consistent problem where it will not let me change the rom as ( i think ) my SPL version is still 3.08 and every ROM bombs out with "this is an upgrade only"
help me downgrade my IPL/SPL back to 1.02 pleaseeeee
cheers.

Default Do Not Upgrade To 3.08 !!!!!!!!!!!!
Hi,
i have T-Mobile MDA and Im stuck with spl 3.08
I did everything.......... and I mean EVERYTHING and nothing helps me bring back my MDA to the original T-mobile software or downgrading the SPL.
1. Downgrading my IPL to 1.01 (using button rom)
2. Unlocking CID with lokiwiz (successfully)
3. Running button rom again
The SPL still stays 3.08 after doing the above...
If there is another way to downgrade the SPL 3.08, please let me know. I really need the T-mobile original rom version.
Thanks so much.

Thats your problem, reflash the 1.02 rom again, both IPL and SPL have to be the same.

hey nottoosmart
i know... i need to find a way to drop the SPL back to 1.02 or thereabouts. i cant flash back to the T-Moblie 2.26 ROM coz it says my SPL is too high. i upgraded my IPL and SPL using a rom updater now whatever i try i cannot drop the SPL version.

Downgrade Locked G3 with 3.08 IPL/SPL

I have read the guides to unlocking and from what I see there are none that work on 3.xx SPL/IPL. I was able to downgrade the IPL but never the SPL.
I have seen several threads that say if you flash button rom (several times) it will eventually downgrade the SPL also, but all night as I worked I flashed the button ROM (about 12-15 times) and still can't downgrade the SPL from the 3.08, only IPL goes to 1.01
Tried the original Cingular ROM and it isn't accepted (I think because I have a higher SPL than the original 2.26), tried using the ShellTool, Tried SoftSPL too but none worked.
IS THERE A WAY TO DOWNGRADE THE 3.08 SPL SO THAT I CAN USE THE LOKIWIZ02 OR LOKIWIZ03. I saw a thred saying that 3.08 can't be downloaded but I also saw SEVERAL saying to just keep insisting with the Button rom that it will eventually work (but after almost 15 consecutive tries I've had it).
Any help would be GREAT.
thanks

Button ROM doesn't work for that. I tried numerous times too. The only ROMs that work to downgrade to anything else from 3.08 are the OEM releases from either T-Mo or AT&T.
The Cingular ROM isn't accepted because it checks the OS version number. I had to try several peoples' ROMs until I found one with a low enough version number to where the Cingular ROm could flash on top of it.

Try to flash T-Mobile 2.26 to bring it down to ipl/spl 2,26 then go for button's 1.05,hope it'll do the trick.
Good luck
p.s. you can try the wizard_love_Rom also,lol

I want to downgrade my phone, too. but the original T-Mobile AKU2.0 say while reading the phones ROM-Version "only update"... so, with this no downgrade is possible.
How can i CID unlock with AKU3? I want to flash a new ROM from xda-developer as well... damn

You could probably extract the nk.nbf and use the standard tools to flash it.
The nk.nbf can usually be found in a .tmp folder in c:\documents and settings\yourname\Local Settings\Temp

Thanx for your Hint... but which "Standard-Tool" should i use?
Sorry for this silly question, but i am new in experience with my vario
