# Unsigned 32-bit Integer ## Identification `AP`, `BL`, `CSC`, and `HOME_CSC` are Samsung firmware-package components; `SM-T870` is the Galaxy Tab S7 Wi-Fi family. [[UDisks2|UDisks2]] exposes storage objects and filesystem operations through [[D-Bus|D-Bus]]. `4294967295` equals $2^{32}-1$, the maximum unsigned 32-bit integer. [[Mobile Country Code|MCC]] and [[Mobile Network Code|MNC]] identify a public land mobile network; `Cell ID` identifies a radio cell within carrier/location-area context. ## Notebook evidence - [[Scanned_20260730-1659#PDF page 4 — Galaxy Tab S7 firmware, UDisks2, and cellular identifiers|PDF page 4: Galaxy Tab S7 firmware, UDisks2, and cellular identifiers]] — The `T870` strings identify Samsung’s Wi-Fi Galaxy Tab S7 model family; Samsung’s official update history confirms SM‑T870 as Galaxy Tab S7 and places `T870XXU1BUAC` in the Android 11-era build lineage. `AP`, `BL`, `CSC`, and `HOME_CSC` are the familiar component slots used by Samsung/Odin firmware packages: application processor/system image, bootloader, regional/customer software configuration, and a user-data-preserving CSC variant. ## Relationships and overlays The source places this record in an evidence cluster with [[D-Bus|D-Bus]] · [[Mobile Country Code|Mobile Country Code]] · [[Mobile Network Code|Mobile Network Code]] · [[Samsung Galaxy Tab S7|Samsung Galaxy Tab S7]] · [[Samsung Odin Firmware Package|Samsung Odin Firmware Package]] · [[UDisks2|UDisks2]]. The occurrence contributes to the notebook's larger model of [[Identity Continuity|identity continuity]], [[Device Sovereignty|device sovereignty]], and [[Continuity Architecture|continuity architecture]]. ## Evidentiary status and open leads Resolve the exact carrier represented by MCC 310/MNC 410 in the notebook’s time frame and the meaning of “[PERSON REDACTED] MI Router”; compare with device logs if archived. ## Source - [[Scanned_20260730-1659|Scanned_20260730-1659]]
