[Android Q&A, Help & Troubleshooting] excaliber8878:
Based on the below bootloader information and the 'ls -l /dev/block/platform/mtk-mdsc.0/by-name' results, can anyone help me understand whether I am able to copy a new boot or recovery image to my generic MediaTek tablet using dd. I am able to access fastboot, but fastboot doesn't seem to have very many commands available, or it has proprietary fastboot commands specific to this generic device. In fact, there is a dedicated partition named 'flashinfo' that I can copy using dd but I do not know how to view (decompile) this .img file. I have pulled an .img file from every partition if this would be helpful to someone willing to take the time to help me out. Any direction would be greatly appreciated.

How do I unlock this bootloader? Can I use dd to replace a partition based on the bootloader data provided? Notably I tried using dd to copy a Magisk_Patched.img to the boot partition, but both efforts resulted in a bootloop

(I also noticed that the lk (Linux Kernel) and boot partitions are distinct on this device. Is this unusual? Is it possible that this is why Magisk is not working?)
