I have installed this version of the ROM, but my device will not boot into Android.

The boot animation is displayed for a very long time and then the device resets and boots into the Recovery menu.

Is this a known issue?

I wiped the data, system and cache before installing.
Not a ROM related issue.

I upgraded the recovery software to the latest version and it installed and booted successfully.

    Hi psychem

    Please allow me to advise you on this in advance to avoid uneasy situations in the future. You are free to monetize your projects as you please but commercial projects will not be endorsed by XDA (exceptions: Advertise with XDA, Paid Software, mod approved projects (rare but please talk to us)). In other words – just to state this very clearly: you are forbidden to request money in exchange for a service or product on this forum. This does not, however, affect your right to ask for optional donations. Our forum rules address this in several ways:
    7. Do not sell or trade on the forums.
    • If you wish to advertise a product, simply contact us. We can provide ads but you are not permitted to just post it in the forums. If you do, it will be removed and you're likely to receive a ban.
    • The buying, selling, trading and / or exchanging of any item is now prohibited on XDA, in any forum or via Private Messages. We now use www.swappa.com
    8. Donations.

    As a user, you're allowed to ask for donations in your signature as a thank you for your hard work, however donations up front are not allowed. This forum is about sharing and not about getting paid to do something... that is what your job is for.
    11. Don’t post with the intention of selling something.
    • Don’t use XDA to advertise your product or service. Proprietors of for-pay products or services, may use XDA to get feedback, provide beta access, or a free version of their product for XDA users and to offer support, but not to post with the intention of selling. This includes promoting sites similar / substantially similar to XDA-Developers.com.
    • (...)
    13. Advertising and Income Generation

    Commercial advertising, advertising referral links, pay-per-click links, all forms of crypto-mining and other income generating methods are forbidden. Do not use XDA-Developers as a means to make money.
    Sorry to burst your bubble so directly but we prefer to communicate in an unambiguous way. I hope this provided some clarity for you. Do feel free to contact me (privately!) if you'd like to know more.

    Stay safe :)
    So the Author created a build with bugs, then, he fixed those bugs and asks money for the new build.
    lol, That's smthg I see first time here. I do respect the money request, any job should be paid. But cmon, $$ for the build?

    Also, you learned from this forum, as seen from your posting activity, how to do these builds, and now you are asking money from One plus X ancient owners, that's like 10-50 people not more. lol


    psychem please fix the mic sound it pretty horrible during call. Yes it is louder but it isnt clear.​
