bunnylock

bunnylock locks bands, RATs and cells on Android phones. It works through root or Shizuku and picks the right way to talk to your phone's modem.

Modems are weird, and vendors rarely implement the same controls in the same way. Something working on one phone does not guarantee that it will work on every phone with the same chipset or Android version.

Features

Depending on your phone, bunnylock can:

• lock 2G, 3G, 4G and 5G bands

• force a RAT, such as 4G only or 5G only

• lock 4G and 5G cells by EARFCN, ARFCN or PCI

• choose 5G SA, NSA or both

• lock to one mobile network

• turn VoLTE, Wi-Fi calling and carrier aggregation on or off

• restart the radio or reboot the modem

• open the built-in band menu on supported Samsung phones

Supported phones

bunnylock tries root first, then Shizuku. Shizuku started through ADB can do less, though some MediaTek and Unisoc phones can still lock bands with it.

It picks a backend for your chipset, and you can change it in Settings:

• Qualcomm: QMI

• MediaTek: AT commands

• Pixel (Tensor): the modem's NV settings

• Unisoc: AT commands

• Anything else: Android's radio HAL

If something doesn't work, copy the diagnostics from Tools and include them in your report.
