Alternative to official Lenovo bootloader? Website is not working

[Dashiya]

Heya,

I am trying to change ROM on my Zuk Z2 Pro following these steps to unlock bootloader:

1. On your Lenovo phone, go to Settings » About » Status information» and make a note of your device’s Serial number.
2. On your PC, open developer.zuk.com/bootloader websiteusing Chrome browser.
3. Once the is opened, right-click anywhere on the page and select “Translate to english” from the context menu.
4. Read the terms & conditions and then click on the Carry on button at the bottom of the page.
5. On the next page, select your device model from drop-down box.
6. Next, enter your 8-digit serial number into Serial number box.
7. └If you’ve a 7-digit serial number, add a zero (0) to end. If you’ve 6-digit serial number, add two zeros (00) to the end.
8. Provide your Email ID in the EMail box. Bootloader unlock files will be sent to this E-mail ID.
9. Tick/check-mark the the two conditions above submit button, and then hit the SUBMIT button.
10. └ You’ll get a message on screen in chinese. It means, the unlock file has been sent to your E-mail ID.
11. Open your email account, look for an e-mail from Lenovo and download the unlock_bootloader.img file from the mail

However I am getting stuck at step 9 and 10.

after all previous steps on developer.zuk.com/bootloader I was redirected to lenovo site and I was asked to login with lenovo account - which I created and logged in however after that I received the following message:

Sorry, the page you visited is missing
1. Please recheck the URL you entered.

2. Please click the browser "refresh" button, or try again later.

Return to the home page ( 9 s)

Also checked my e-mail - no sign of the file.

so.. it looks like I am now stuck.....
Prior to posting here I googled for other guides but every time I find a guide for this model it is using the official lenovo website way...

I am looking for how to unlock it not the official way, help please!
