Be advised, this crDroid custom ROM is a WIP (Work-In-Progress) version and it has some bugs in it. We urge users to go through the entire prerequisite and tutorial procedure before going ahead with the installation procedure.

What's not working?

  • CM specific functions may not be completely functional (CM Themes)
  • Cast can only cast screen audio plays from the device
  • Camera is really slow if selinux is set to enforcing (the ROM comes with selinux in permissive because of that and some other selinux issues)

Prerequisites (things to remember before installing Custom ROM)

  • This new crDroid Android v7.1 Nougat custom ROM has to be installed on Quark models –Moto MAXX/Turbo and Droid Turbo - XT1225, XT1250 and XT1254only. If tried on other devices, it might brick them [to check your device model: Go to Settings >> About phone >> model number].
  • Though installing custom ROM improves the device's performance and UI experiences, it makes the company warranty void; the company will no longer be liable to provide updates in future [users can restore the warranty by flashing the device with stock-ROM].
  • Make sure the device is rooted before going ahead with custom ROM installation.
  • Installation of custom ROM requires clearing memory in the phone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
  • Make sure USB driver is installed on the PC or else your device (Galaxy S4 LTE) will not be recognised by the computer.
  • Make sure your device has more than 80% battery, or else there is a chance of the smartphone getting temporarily bricked if the installation process is interrupted midway.

[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) Android devices. If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or being permanently irreparable. IBTimes India cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked. Hence, users are advised to proceed with caution.]
