Hi, I need help. I have three Ubox, two of gen 2 and one Pro. One fo gen 2 got somehow slow and stop a lot, and I did factory reset which usually solve this kind of issue, however, this time, it messed up and now I can not download whole APP at all. My friend told me to download APK on Unblock tech site on USB stick and upload it on gen 2, and I looked for it, but couldn't find. Please provide info if you have any. Thanks!!

PS I sent same note to Unblock tech via their website and Facebook messenger few weeks ago, but no reply.
