Chosen Solution

All I get for booting up the phone is: ‘Samsung powered by android’ What I have tried:

  • Letting the phone charge up for a while
  • Reflashing firmware on the phone, correct matching to the serial number of the phone by checking via Samsung Smart Switch
  • Booting recovery, does not get into recovery, stuck on logo again. A couple of questions:
  • There are no signs of the phone showing symptoms of DRK (Device Root Key) being damaged, I would prefer not to trip the KNOX warranty from flashing custom binary unless I need to. Like custom kernel to check DRK if it’s bad or custom recovery to see if it will boot that
  • I know that a bad battery can cause this (but this time it’s not actually bootlooping, it’s stuck on the logo), should I try an replacement battery? I got one on hand, but if there’s anything else I can try before I try this I would appreciate it a lot. Note that the battery actually does hold charge meaning that there is a lower chance of it being the battery at fault, the last time I had to replace a battery to fix bootloop was because the cable to the battery was partially damaged.

What is the longest time you let it sit at the logo? What model number does your phone have? The flash you attempted, was it lower or higher than what was on the phone already? You may have to flash it with the latest Android, then side load the latest security updates. The new thing with KNOX is that your phone will sit at the boot logo if you flashed to downgrade. Also, I noticed you didn’t say you cleared/wipe cache/ dalvik and factory reset in recovery. I am assuming you did, but you didn’t list those steps?
