Duo-band firmware for the Qin F21 and Tiq M5: both the EU and the US LTE bands on one phone.

Qin F21: F21DuoBands.apk installs it in one tap on a rooted Qin F21 Pro (before v3). It keeps the phone's IMEI and Bluetooth and Wi-Fi addresses, sets up VoLTE for Israeli networks, and reboots when it's done.

Fastboot files per phone (prefixed f21- or m5-):

  • *-md1img_a.duo.signed.bin modem image, re-signed to the test root
  • *-nvdata.duo.img nvdata partition
  • *-nvram.duo.bin nvram backup partition

Flash from fastboot on the active slot, and back up stock md1img, nvdata and nvram first. Flashing nvdata and nvram replaces the IMEI and the Bluetooth and Wi-Fi addresses with placeholder ones (the app keeps yours), and fastboot doesn't set up VoLTE.
