Heya... I'd just like to confirm that our free C500 SIM unlock tool works perfectly on the C550 (thanks nedge2k for the testing) ;)

To decert (application unlock) the C550, simply change these keys using the attached registry editor (it's the freeware PHM editor signed by HTC):

HKLM\Security\Policies\Policies\00001001 = 1 (RAPI)

HKLM\Security\Policies\Policies\00001005 = 40 (Cert)

Sorry to be an idiot but I'm trying to locate the C500 sim unlock software but cant locate the link.

Can you help?

DeCert & Unlock worked nicely for me on C550.

one point though, I copied the cert to the phone before changing the registry. It then wouldn't install the cert until I deleted the cert and copied it to the phone again. So do the registry changes first, then copy the cert onto the phone.

Both Regedit and cert copied over USB cable with no problems - no card reader was needed.

An excellent tool !

I used the original instuctions fine on my old C500 last year. Now on the C550, I've installed the cert.cab and regedit, changed the register values exactly as shown, run SPVServices on my PC with the C550 connected up via ActiveSync, typed "AGREE" where requested... and nothing happened. I was asked to type AGREE again, and again. I thought the phone might have been unlocked without SPVServices saying so, but when I tried another SIM card, my phone showed "SIM Locked, enter Unlock code." Any thoughts? I need the SIM unlocked for Aug 16, help would be much appreciated!

Could you eventually make it? Were you actually able to launch the .cab from your phone. Otherwise, it could be that it still need to be app unlock first.

Tks for your reply but no, I couldn't do it. I did launch the .cab but the phone remained locked. Eventually, I took it to a place in Oxford St and paid

I got the new Tmobile Dash (HTC S620). I followed these steps but the registry appears to be read only. I can't change any of the values. Either the registry is locked by tmobile or this regedit program doesn't work on this model. One thought is that I can't unzip it on the phone... I don't see a way to do that. So instead, I unzipped on the PC and copied the exe. It seems to work, but some of these posts make a big deal about unzipping on the phone.

Any other ideas on how to put my own root cert on this phone?

Welcome to the forum ISOFREAK

You don't need to type =

If you navigate to the key and select it the value will be displayed (depending on the reg editor you use uou might have to use the menu to edit the value) then you just change it.
