If the certificate is wrong or expired, you need to apply for a certificate signature

You can go to the signature center of Ouku.com to apply for the certificate of your mobile phone

The process is very simple. Convenient.

First of all, you need to register for free.

Then fill in your mobile phone model and serial number as required.

Just submit it at the end.

It usually takes about 12 hours to complete.

Because it produces certificates twice a day at around 10:00 in the morning and 19:00 in the evening

So it is much faster than Symbian, Mobile Home and so on.

And supports online software signing.

No signing tools are needed

Just upload the software that needs to be signed.

Note that it is in SIS SISX format

The signed software will be downloaded later.

Just install it directly

It is very convenient.
