 The A20XKC series oddly only has the open source code published up until 1.070XX, however phones with higher version numbers on those models have been confirmed. This list only contains confirmed versions we have seen so far.

 === Rooting ===
 {{template>Main|article=Rooting the Kyocera DIGNO Keitai 4}}
-Due to the MediaTek chipset, these phones can be rooted using [[https://github.com/bkerler/mtkclient|MTKClient]]. Rooting allows users to access system directories, run programs with superuser access, install GMS (LINK), and more. This capability has been verified on the A202KC, A203KC, A204KC, and KY-42C (up to version 1.090) variants, though there should not be any difference on the KY-43C.
-The 1.090 updates for the DIGNO 4 devices, released in mid 2025, patched the exploit in the preloader used by MTKClient to crash the DA. It may be possible to circumvent this by shorting test points inside the device. A method that does not require disassembly has been found. Please join one of our [[:start#community|community]] servers for more information.
+<note important>Users on the KY-4XC should be aware that if they are planning to root their device that they should not connect their device to a network until they have done so. Unlike the A20XKC, the KY-4XC is capable of updating outside of Japan. At this time there is no known way to root the KY-4XC past version 1.090XX.</note>
