There are a few questions about the prototype.

    I purchased the xz2premium phone in the local flea market and now I have the following questions to ask for help.

 1, this phone may be a prototype, IMEI: Removed, then it can normally receive the official OTA update?

 2, can you write rom?  For example, the version in mainland China is replaced by Hong Kong because Google cannot use Hong Kong and Taiwan except in China.

 3. How do I view the difference between this phone and a mobile phone that is normally sold?

 Below I have provided some mobile phone information in the form of pictures, please refer to.

 Thank you!

Re: There are a few questions about the prototype.

Hi @newbaby, welcome to our forum!

Your IMEI has been removed as it is not allowed here at our forum, but it is a prototype. Prototypes are not meant to be used by end users so I can't really provide any support for your device as it is not retail devices.

For questions regarding flashing a different firmware and so on, please see our developer website on the link below.

I'm sorry that I can't be of more assistance, but I hope you understand why.
