I installed the sx lite mod chip & ran smoothly first. Then, I select the original OS to enter and I made a mistake to perform system factory restore. The process was failure at final. I powered off the switch lite & turned on, the screen was blank, no any boot logo displayed. The mod chip LED was 3 blue then white instead of green. I detached any flex cable from the mod chip & retry but in vain. Did the bootloader corrupt? How to fix the problem? thanks a lot.
