Exceeding clients’ expectations is my greatest asset. For me, I treat this profession as a full-time job or rather a business of my own. Every minute I would try to do something for my business. And in this way, I have differentiated myself from other competitors by thinking outside the box. I am constantly looking to use advanced technology to stay ahead of the rest and I also pride myself on providing an unparalleled service to all my clients. What I look forward in this profession is to develop a long-term relationship with all my clients

Hi, Senior XDA Developer here. I've delivered similar bulk processing android firmware before. This one seems a little odd though! I need to know why we need to downgrade the devices to android 9, maybe we can solve the issue in android 10 as well? Or still sort it out. Please have some discussion over chat to clarify things. I gurantee a best advice at least. Regards: Zubair!
