"Stuck on "Samsung" logo"に関する回答This is by far the best set of responses to the problem of the Galaxy Tab 4 (SM-T530NU) getting stuck on the boot screen. First try Power + Vol Down If that doesn’t work, go with Power + Menu + Power Up ) hold until the recovery menu appears and then re-boot from scratch (all data will be lost) If none of that works, reflash, but if you’re in the US, do NOT use the recovery files from SAMMOBILE. It will make your Tab into a Nook. (A working Nook, but a Nook nonetheless.) Fantastic and very simple walk through of flash using Odin at https://www.youtube.com/watch?v=vYsXDFi4... If you want OEM OS, get it from XDA at https://forum.xda-developers.com/tab-4/general/links-stock-galaxy-tab-4-firmware-t3013128 That’s Android 4.4. Then if you want 5.0.2, simply go to Setup/General/Software Updates/Update Now and you’ll get updated OTA without having to lose data. BIG Thank You to XFix, whose answer got me to the point where I have confidence and the ability to take this tablet another million miles from here.
