The most popular custom recovery, TWRP, is now officially available for two more devices: the Samsung Galaxy Core Prime and Huawei P8. Because Core Prime comes in two variants, it needs to a clear mention that the compatible Core Prime device is the one featuring a Qualcomm processor, and is labelled as coreprimelte under model no. coreprimelte.
The TWRP recovery is available is both .tar and .img file formats for Galaxy Core Prime, while it’s available in .img format for Huawei P8.
How to install
Otherwise, for Galaxy Core Prime, use Odin software to flash the .tar file with device in download mode. See this Odin guide for help. It’s for Galaxy S6 but would work perfectly for your Galaxy Core Prime too.
