  1. Hola ya realice los pasos como dices , y tambien hice “Debe parchear el firmware que es el mismo con el firmware instalado actualmente” lo que dijste pero al momento de que ODIN arranca llega a una etapa en que solo queda leyendo el parche y no pasa de alli

    • We will update the TWRP version once we get a stable method. But Core series mobiles have minimal hardware so Custom ROMs may not work as expected.

  2. To be honest, I don’t want to root my A2core. The main reason for wanting to root is to increase internal memory. I have been deleting lots of useful apps that I should be used to create space for the crucial ones. So, my question is, how can I increase the internal memory of my A2core and also possibly improve the virtual ram as well?

  3. I’ve followed the above steps up to this point;
    I don’t get a .tar file as output. My output file after patching in magisk is “magisk_patched.img.”
    I don’t know what I’m doing wrong here. Please help.

  4. Hey,
    I doubt the renaming part. You told me that you have to copy the boot.img.lz4 to the LZ4 installed file, and from there, you told me to rename the lz4 file, so which one is it? is it LZ4 or boot.img.lz4 . And secondly, how do you copy the renamed .img file. To your mobile? to install in magisk?.

    • After yo9u converts the .lz4 file to the .img file, There is no need for rename. It will automatically convert the file to boot. img.
