Flash a Personal Hopspot
Choose your exact board and flash a signed release straight from your browser: every byte is verified locally before it touches the device. Update keeps your device's data. Fresh install erases everything, and asks for its own confirmation first.
Selected target
nRF52840 + SX1262 + KCT8103L PA
Prepare the board
This board uses its UF2 bootloader; the website reads its local descriptor and downloads the matching verified UF2 file.
- 1Connect with a USB data cable and double-press RESET until the HT-n5262G drive appears.
- 2Select INFO_UF2.TXT from HT-n5262G. The file is parsed only in this browser and is not uploaded or retained.
- 3Prepare the signed release after the detected SoftDevice foundation appears.
- 4Copy the downloaded UF2 to HT-n5262G and wait for the copy to finish. The drive disappears when the device reboots.
Review and verify
Waiting- 1Confirm the exact board pictured above.
- 2Select INFO_UF2.TXT so the browser can resolve the exact SoftDevice foundation without uploading the file.
- 3Prepare the matching release artifact; its Minisign signature, UF2 structure, byte count, and SHA-256 are checked locally.
- 4Download the verified UF2, follow the board preparation instructions, and copy it to the bootloader drive.
- 5The bootloader drive disappears when the device reboots.
No full-chip erase. Every published byte is signature- and hash-verified before device access.
Confirm the exact board before preparing its verified UF2 download.

Shipping targets flash from a signed public release. Boards in hardware qualification and final bring-up sit beside them and graduate in place.
