Blue screen on a used modded switch (seller says that was a update on OFW that caused it)
Hi guys, i need help.
This is a uptade of my latest post https://www.reddit.com/r/NxSwitchModding/comments/1te8z9v/just_bought_a_modded_switch_lite_with_vertical/
I found a used, modded Switch Lite online and bought it. The seller stated that they updated the official system and, after that, could no longer access CFW. When the Switch arrived, I put the SD card into my PC and noticed it didn't have a NAND backup or an emuMMC file. I copied the latest HATS pack to the card, turned on the Switch, and when I try to access OFW, I get a blue screen. Is there any possibility that the blue screen is caused by the update? If so, how can it be fixed? If it's a hardware issue, I will try to return it to the seller.
Edit: An update for those who find this post in the future. It was the SD card and a corrupted update. I swapped the sd card for one I was sure worked and followed the tutorial by Sthetix on level 2 unbrick process, and now it works. I'm going to buy a new screen and finish the repair. Thank you to everyone who gave tips and tried to help.
