Archive for the Samsung Galaxy A52 model A520F, where U10 refers to binary revision 10 and the Arabic word in the name means root. The 9.06 MB ZIP likely contains a patched boot image or root files for that binary. Rooting files are tied to the exact firmware binary, so check the bootloader revision on the phone before flashing, since a mismatch can fail or block a downgrade. Back up user data first and expect that rooting may affect Knox status and some secure features.
