BTW, This so called "alpha" code is better than many well-known global organisation's release code. Presumably, when it is release code, it'll make me a cup of tea in the morning and change my son's nappies as well? ;)

I assume labeling something ALPHA or even BETA you reduce your legal liability but I agree these guys have done a bang-up job. 8)

Hello all,

To start, sorry for being a very thick dad, I bought my son a spvc500 and I want to unlock it.

I have tried to follow the instructions that have been given here, however, when I try to open the cert. document it says.

"Installation failed, the program or setting cannot be installed because it does not have adequate system permissions"

Can anybody give me a step by step idiot guide to setting this thing up.

Many thanks

If anybody can help I will learn to like the Simpsons. I promise

Hi Nigel. Welcome to the site. I suspect you need to Application Unlock (decertify) your phone first; this allows applications that have not been signed ('approved') by Microsoft, to run on your phone.

Take a look >>here<<. Once you've succesfully app unlocked, you should then be able to run the Sim Unlock app.

wat does Your phone must be application unlocked, and have our cert.cab file installed. This file should be included with the SPV-Services package. We realise this is a big limitation, again it's something we are working around. mean excactly and is there any chace some one could send me everything that came on the cd with the c500 as i didnt get one and i cant connect 2 my computer with out it [email protected] thx very much

visit http://www.microsoft.com/windowsmobile/dow...tivesync38.mspx for the software you need tyo connect to the pc

i suggest you read the instructions again and follow them step by step, its difficult to make them any more clear

aplication unlocking allows your phone to run applications that normally would not run due to restrictions which oragne put on the phone. see the articles section for instructions on how to removethe app lock

Well! I Have change the Orange rom to I-Mate rom and now I get a DATA CRASHES message. My old C500 doesn't even connect via activesync.

Is it dead? Do you know any way to make it return to life?

I want to use your great app to unlock my phone but before I need return to Orange rom.

Any help or is better to the funeral to my old and dear phone? Thank you

Thanks for the great service provided, guys!

I just have one question: if I purchase an Orange SPV C500 and unlock its SIM, can I use it without any trouble in the T-mobile network in the US?

Thanks much!

Having app-unlocked my orange spv c500, I attempt to install the cert.cab file, but I get the error 'INFO Cert.cab failed to install on your device'. Can you think of any reason why this would be the case?

EDIT: In fact, I cannot seem to install anything any more, including the Security.exe sent by orange to allow app unlock/locking.

Can someone point me to a thread which describes how I go about diagnosing this fault.

EDIT 2: Worked a treat this time. Did a hard reset, then installed security.exe received from [email protected] Disabled Security. Installed Cert.cab. Ran spv-services.exe and Unlocked. Now to re-install apps.

Worked a treat, excellent thanks!

Will this need to be redone if I update the ROM on my C500?


You are joking, right?
