Hacking Question switch lite blue light->green light->black light,but black screen.

[jzhoulon]

Hi,
I have an issue on System update: I have a SX core installed switch lite. it has no enumand / nand backup, and I update the system to 10.2, and then it can not boot up. And then I replaced with the newest boot(3.0.5), when turn on the switch with "+", it will have 1 minute's blue light shining and then switch to green light, I can see those 3 icon(CFW, OFW, option). When I click the CFW, OFW, the light will turn to black and the screen got black too. no matter how many minutes I wait, it still got black screen. Does any one knows how to resolve this? Thanks very much.

Check your SD card with H2testw. If it's ok full format in fat32, redownload latest boot.bin and try again. If it's not ok get a new SD card.

Are these sd cards samsung by any chance?

Hi, you can try to use genuine boot to boot the original firmware.
If can boot usig genuine boot, then might because your firmware not updates to support sdxc.

So the SX menu works but after you select something nothing happens?

Can you recreate your emunand?

Where can you get boot.bin from? Is it a file SXOS attempts to access during boot time?

They meant boot.dat. The actual sx os cfw file.

Thanks for the clarification. Now, as stated above, there is another way to boot the system, did I get that right?
Would it help for a switch lite that doesn't show anything in genuine boot? What is this alternative? How exactly do I get my Switch Lite to boot using another bootloader with SXOS?
