Hi,
I had my Mariko version of the switch with SX Core V2 modchip for more than 2 years. Half a year ago, I switched from SX OS to the atmosphere. Everything ran fine till weeks ago; my switch would not turn on anymore, with a few blue blinks then staying white.
At first, I suspected it was a soldering issue, so I resoldered the modchip. The problem still exists. I removed the modchip, and the switch would not boot as well.
So I decided to update the modchip firmware to hwfly 0.7.1. Supposedly it should support the SX Core chip. However, I get like 1 min green blink, then 3 green blinks with 1 red blink.
I managed to use the debug mode of the hwfly firmware, with the diagnostic mode, I found the error code is "BAD00110". I checked their source code, and it means 'ERR_MMC_SEND_OP_COND_FAILED'.
I also tried to use a clean SD card with FAT32 system with Hekate payload, still had a black screen.
I have no clue what to do next, maybe it is a hardware issue beyond the modchip? Or is the NAND damaged?
I would appreciate it If anyone could give me any advice.
