New to this, so be gentle!! My sons Galaxy Tab E (SM-T560) appears to frozen on the boot screen (beyond the animated logo). Having googled for cause/resolution, it sounds like it needs flashing if that's the right term. I can boot to the download menu e.g. Odin etc, but am having trouble finding a firmware download. Have tried both Sammobile & Updato, and can find the right download, but for the life of me, cannot download from either site on the free membership. Even tried the premium memberships but both websites seem to be broken when it comes to completing any transaction.
Any pointers, advice etc will be most welcome.
