How do I set the "Current Read-only State" to "No"? The regedit "writeProtect" method doesn't work. Re-formatting doesn't work. No physical switch on a microSD.

Card is read by card reader of the same brand.

What happened prior to this situation: Card was working top-notch. Then I didn't use it for a couple of months, so it was just laying around in a suitable environment. Now I plugged it in and it is set to read-only.

P.S.: It is a Transcend card, not SanDisk.
