Is there a way to flash the Global ROM onto a Tencent Switch?

Tencent Switches are patched. We don't know if SX Core would work on it, but if they do, then only way is to make emuMMC, but current implementation won't pass checks for anything except your own backup.

 

SX Core does work with tencent units, I have personally tested it. Using emunand does not help with the restrictions as it is created based on your sysnand.

 

Yeah it wouldn't be like flashing a complete "ROM", you'd likely have to get the decrypted files from someone else's NAND or maybe from updates if everything needed was in there, then add them into your own (emu)NAND. Code might need patching, who knows.

I've seen no technical discussions and barely any mention of the Tencent Switches on this site, have you checked any possible Chinese communities to see if anyone has looked into it?

 

Are the current emunand implementations console-specific? My thought is that someone could make a file-based emunand on an international Switch and then load them on one of these units.

 

no, global/tencent firmware is same, firmware auto select region content nca by hardware info, you flash global firmware, system always tencent version

 

^ code patches would be the way to go then.

 

1 backup tencent switch prodinfo
2 edit prodinfo file 0x3510, change 04 to other region, 00=jp 01=us 02=eu
3 0x351e 633b is crc checksum, need change to correct value
4 restore prodinfo, if you not change crc checksum to correct value, restart will black screen in boot
5 use sx installer or goldleaf delete /system/save and savemeta
6 factory reset your tencent switch, region will change to your changed version

region value checksum
jp 00 66FF
us 01 663E
cn 04 633B

 

only changed 1 byte, you can rechange to 04 for restore

 

important!!! your device number and certificate can't change, always tencent version still, I don't know if it will be ban by nintendo

 

Now I'm curious what changing it to 03 would be. Korea?

 

03 australia
05 korea
06 taiwan province of china

 

Will this also change the keys so they can play eshop games? This review said that they can't because of different keys but I wasn't sure if they're keys stored in the efuses or the firmware. https://forum.devchroma.nl/index.php/topic,216.0.html

 

no, but you can direct register your changed region eshop or login your global nintendo account

 

sorry, I've ignored crc checksum value, backup is very important

 

region value checksum
jp 00 66FF
us 01 663E
cn 04 633B

 

has anyone tested this method yet? I have a tencent switch with sx core and region lock is killing me.

 

can the switch be bricked by doing this ?
