SOLUTION FOUND -CID/sim UNLOCKING FOR WIZARD WITH AKU2 ROMS.

warnning; does not work with g4 wizards!!!!!
this steps are to cid unlock and also to unlock sim in the folowing devices; qtek 9100, i-mate k-jam, mda vario, orange spv m3000, o2 xda mini s, dopod 838, Cingular 8125
first; you must make a full backup of you wizard before doing this , I personally use [wizBackup.exe] posted below for my backups and restores. This is not mandatory but could save an enormous amount of trouble.
I as most people with a wizard with the aku2 rom found out that it cannot be cid unlock with lokiwiz tool, you will get the following;{error:itwritedisk-an internal error occurred}.
. that is till now.
downgrade rom here http://dl.dropbox.com/u/7696581/htc%20wizard/CUSTOM__RUU_Wizard_1050412_WWE_101_11210_WWE.exe
note- this steps is for unlocking the cid of the wizard with aku2 rom.
how to cid. unlock all wizard variants ( that have the latest rom build )
first download custom__ruu_wizard_1050412_wwe_101_11210_wwe. rom from the ftp site from the above link, unpack it and just click the romupdateutility_wizard_noid.exe to start downgrading. Simply follow the prompts.
after the rom are loaded go thru the initial setup as you would with any rom.
now download the (lokiwiz02b) from here;
http://dl.dropbox.com/u/7696581/htc wizard/CUSTOM__RUU_Wizard_1050412_WWE_101_11210_WWE.exe
Make sure you unzip lokiwiz to the root o the c: drive.
please copy the whole lokiwiz folder to the root of the drive,not the contentents of the folder!!!!!
and follow the instructions .do not forget to copy the cab file(enable rapi) to your device and run it before running lokiwiz.
Now run lockiwiz and unlock your machine, your machine will reboot itself. if yoy see an eroot while unlocking that says;
..............................................................................................................................................................................
CopyFileToTFFS(cidunlocked.bin:0, 0, 00010000)
ERROR: ITWriteDisk - An internal error occurred.
this means that you device not been unloked......try again............
.................................................................................................................................................................................
That’s it your wizard is unlocked. Make sure yew keep the [lock_backup.bin] in a safe place you may need it for guaranty purposes.
Now flash the latest aku2 rom from your provider.- [very important,to avoid future problems wit rom updates]
then u can flash any rom you want.
question: if i cid unlock and sim unlock my phone (after installing custom 1.5 wwe rom) and then i install latest aku2 i-mate italian rom, will the sim unlock (and cid one too) be preserved?
Answer: i can confirm that that upgrading to the latest aku2 rom the wizard remains cid unlocked.
Special thanks to the author of the above cooked rom [button] also to machinagod for the lokiwiz tool and joninla for finding the downgrade rom, molski for is input and everyone that contributed to the cause.
do not try to downgrade using an older wizard rom other than the one posted above it will not work
also this {how to} is for the htc wizard only it may work with other devices but i don’t know, so if you turn you device into a brick do not blame me. use it at your own risk
if you device is from a operator like: 02, orange etc... You will void your guaranty unlocking cid, but don’t despair, if you keep the [lock_backup.bin] file that the lockiz tool generated you can restore cid to factory default.
this proccess only needs to be done once in the wizards lifetime.
Enjoy;

donate if you like my work

Faria, can you tell me if this process will do it for the HTC Prophets with rom 2.x ???

I've got an imate JAMin with aku2 from factory. Just downloaded older Imate Rom... will try the process when i get home

it may be possible,if you have an old custom rom for your device ,found this;
On the one hand, HTC Prophet is a complete copy (both software and hardware are meant) of HTC Wizard. On the other hand, it's equal to HTC Magician in appearance. That is why today review will be quite short, we will only discuss external elements and a new camera, all other aspects were highlighted in the review of HTC Wizard.
http://www.mobile-review.com/pda/review/htc-prophet-en.shtml

Hi Faria, thank you for your HowTo!
Now i know the wizard remains CID unlocked after the upgrade and that's good. I only hope that it stays SIM unlocked too.
Bye

Sadly, cant move back to older rom... keep getting error message saying the nk.nbf file is not valid/older than your current file.
I guess we just have to wait for an updated version of Lockiwiz

sh*t forgot to post the address to the downgrade rom.here it ftp://xda:[email protected]__RUU_Wizard_1050412_WWE_101_11210_WWE.exe

sorry

I told you Faria that it can be done
Great that it worked out okay, I can imagine how happy you are feeling right now
Nice how-to by the way.

mm..i am currently using T-mobile MDA Vario with the original rom
is that mean i don't have to apply it to unlock the cid?
i just use the lokiwiz 2b to unlock the CID, after it, even i upgrade to the newest rom e.g. the new O2 rom, my CID still remain unlock?

HEEEEEEELPP !!! ROM DOWNGRADE ON XDA MINI S

Hello everybody !!
I just spent about 28 hours reading the threads in order to change my GERMAN O2 XDA MINI S (Wizard) ROM. Into an english one.
For that matter I know I need to unlock my CID, but since i have the latest ROM installed, IPL 2.21.001 and SPL 2.21.001 Lockwiz won't work !!!!
so I tried to Downgrade my Rom in order to make the Lockwiz work, but I am not able to find a suiting German Rom anywhere on the Net.
So I was wondering if nebody would be kind enough to tell me where to find and older German ROM or how I can avoid DOWNGRADING and simply unlock my CID
best regards ... Bayardo

Since you have a G4 boot chip (the tailing .001 in IPL and SPL tells that) you CANNOT downgrade your ROM to 1.x version.
DO NOT TRY INSTALLING A 1.X ROM: YOU'LL BRICK YOUR PPC!!! DO NOT FOLLOW FARIA's PROCEDURE TO CID UNLOCK 2.X PHONES: IT WON'T WORK IN YOUR CASE ('cos you've got a G4 boot chip).
This means that you will NOT be able to CID/SIM unlock your phone with lokiwiz 0.2b (however you can still use lokiwiz 0.3a to SIM unlock it, but no CID unlock).
But don't despair, you CAN still change your phone language and install whatever 2.x rom you like. The procedure to follow, however, is a bit different: you cannot simply download a rom you like and install it, you'll need to hack it a little first, but the results will be the same!
Basically, all you have to do is get the ROM you like (only 2.xx ROM!!!) and remove from it the IPL/SPL part. Then, you have to flash this 'hacked' rom using a slightly modified ROM Upgrade Utility (i can provide it to you if you want). With this method you're not going to replace the IPL/SPL (bootloader) of your phone so you don't need to CID unlock it (which, at the time i'm writing, is impossible).
To remove IPL/SPL from your ROM you have to extract the file nk.nbf from the ROM and get its content with typho5 tool (search this forum to have more info). Then you have to reassemble a new nk.nbf using nb2nbf. The new nk.nbf, of course, must NOT contain the IPL/SPL parts.
If you prefer, you can tell me what ROM are you interested in and i'll do the dirty work for you. Just let me know.

Hi risidoro,
I am trying upgrade my O2 German Wizrad G4 version into WWE, I followed your instruction & has used nb2nbf to compile a 2.xx rom without IPL & SPL. When I used the update utility to falsh the Wizard, the utility said something like: Error, this update utility is not for your device. etc.
I think I need to used your modified update utility , can you send it to me?
Also my other question is, when I use nb2nbf , what should I put in the model id for my German Wizard?
You advice can help me & many others to solve our headache in upgrading a G4 Rom! Cheers!

For ModelID you can use both WIZARD or Prodigy (i used the former).

does this mean that its on a G3 chip and that i can use lokiwiz03a to CID unlock it and upload any 2.x ROM as i please? and downgrade the ROMs too?

@Bola: you have a 1.x ROM so you can CID unlock your phone with Lokiwiz0.2b (NOT 0.3a). Then you'll be able to install whichever ROM you like.
Bye

I've just published a tutorial that can help those with a G4 or G3 (>= 2.21) CID-Locked device to install whichever 2.x ROM they like.
The tutorial is here:

The HARD-SPL is a little more dangerous than the USPL... I can help you find ways to get any ROM you want on that phone easily enough, but UNLOCKING it again is the hard part. There's not 100% sure fire SAFE way of doing it.

welll, i just installed the hard-spl on my device and it went through
there's just one thing that gets me...
what's the difference with this hard-spl and HTC?
is the only difference is that the boot screen is different or are there more features?
For now, I just need a comparision of what the hard-spl has from the HTC one.

The Hard-SPL is a customer SPL. It's permanent, too. You will have to create your own customized RUU from now on, one that lacks the SPL. You can't flash RUU's that contain SPL because the SPL is now write protected. It's convinient, though, because now you can't accidently screw it up. (It's safe once you have it IN your device. Too many people brick their phones trying to get it in there in the first place, though.)

So now i won't be able to put in the HTC RUU anymore?
All right, sorry i'm being so stupid, but here's another question...
You said that i now have to make my own customized RUUs?
What do you mean by that?
If you don't mind, you could send me a pm, I don't want to spam this thread with my stupidity.

Now you can flash ANY rom you want.
ALL cooked ROms - really all - without the chance of bricking = your device is SAFE.
IF you respect this little thing
every RUU Rom Update Utility
contains:
1. Enterbootloader.exe
2. Rapitool.exe
3. RomupgradeUtility.exe (the one you start)
4. RUUGetinfo.exe
5. RUU ressource.dll
6. RUU_signed.nbh (that is the custom system OS - you can put every HERALD .nbh here postet in touchIT3 for example)
7. SPL.nbh ---- !!!!!!!! delete this allways!!!!!!!!! ------ (it is in all official RUU but delete it)
now you can flash with an official update tool all custom roms for you herald.
But don´t use wing roms - the keyboadmapping is different.
There are good herald roms, too.
Good luck

ERROR [244] INVALID MODEL ID how to get the solution.

when I flash my t-mobile wing. the RUU shows ERROR [244] INVALID MODEL ID
is there any one can help me?
Thanks in advance

Is your device HardSPL'd?
and don't mind the spam guy. Actually, consider yourself lucky. Very rarely do they choose your post as a spam receptacle

Thanks mate, what do you means "Is your device HardSPL'd?"
IPL: 4.17.0002
SPL: 4.70.YANG
please check. why I can not flash my WING with that ROM
But I can flash my wing with os.nb
what's the problem?

asergs method bypasses the cid lock
check your pm

can you post Aserge solution here please?

aserg's method is an outdated way of flashing a rom. It was used in the earlier roms posted on the forum (like the one jimmysong tried to flash)
to use, you will need to find the cab pack for it. Check some of the older touch-it roms for the cabs (especially the non-wm6.1 ones like touchit 2)
from there, remove the os.nb file. Use nbh extract to extract the windows.nb file from an .nbh file that you get after you download a rom. rename that to os.nb. and place that in the folder that the original os.nb was in.
follow the instructions very closely and TO THE LETTER. When using aserg's method to flash, nothing will happen. Or so it seems. Be patient until the .bat prompts tell you that it's ok to hard reset your phone.

Try this;

You can't flash the stock RUU after HardSPL'ing your phone. (You both have HardSPL.) The RUU tries to write over the SPL (which is called HardSPL for a reason...) and it also expects the CID to match the default tmobile RUU.
If you want to go back to a stock ROM you have two options.
Extract the os.nb out of that RUU (which is what Rick GM is talking about) and recreate the NBH without the SPL or use USPL to bypass the CID check.

Help me CID Unlock my HTC P4350 after installing Official Spanish WM6 ROM.. june 2008

Hello everybody,
I bought a P4350 from Spain a few days ago and "unfortunately" the Spanish HTC Official WM6 upgrade was already installed on it. This means that my phone is CID Unlocked so I cannot install an English WM6 version. (I tried to, but in vain...).
I've tried several WM5 device CID unlocking methods, but they all failed.
Can anyone help me?

Unfortunately there is not much information on the web for HTC Herald CID Unlocking as there is for other HTC's (Wizard, Hermes,...)...

HardSPL is CID unlock
or you can USPL an english RUU without the SPL.nbh
or you could just USPL/HSPL a custom rom

ok i'm gonna check for more information about "USPLing an english RUU without the SPL.nbh" on the web.
If you have any pertinent link to provide, it would be useful for me.

Thanks.

I found two different ROMs that include the Touch Dialer (which I find to be a very interesting feature).
Both ROMs included only an NBH file which had to be copied to my micro-sd card. Then I would run my Herald in bootloader-mode so that my device recognizes the file and perform the installation. But it does not.
I don't know what I should do to let my device detect the new ROM file...

I tried copying the NBH file to the RUU Folder of the Flash center and ran it, but it doesn't work either...
