It's possible, just backup your Switchs NAND and Prodinfo first. Then you're safe(r).

I think it would be safe if doing this on emunand ? If something went wrong just throw away that emunand and recreate one. Prodinfo is just a Nand user partition.

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

The key is only different in games from Tencent-Nintendo Switch eShop. If you lose that key seems you will only lose the ability to run Tencent-Nintendo games. On the other hand, Tencent-Nintendo itself should got regular keys bundled since it could run regular nsp games.

factory reset your tencent switch, region will change to your changed version

You cannot factory reset the emunand. Doing the procedure you said on sysNand is waaaaay too dangerous. I guess the closest thing to factory reset on emunand is to install the same version firmware as the current one by ChoidujourNX .

Okay I have tried -- it doesn't work at least on emunand. Because you cannot factory reset the emunand. If you use the factory reset function in ChoidujourNX, you will be thrown back to first time setup, but somehow, the prodinfo will be reset.

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

Great tutor!
So what CRC for EU?

UPD. US works fine if you need all languages
An important note - I could not format the console using Switch, the console was cut off when formatting. So I removed save and savemeta via mtp tinfoil and then installed the firmware via choi with console formatting

and can u tell me what homebrew u used to backup and restore prodinfo ?
thx u very much
 
Could someone please help a newbee here? After sx core I stalled and creating an emunand, where do we perform the changes? On the emunand, or directly on the sysnand? I would prefer to work on emunand, but someone posted there that this doesn't work? Could someone please write the steps in sequence,including which tools to use? Thanks a lot!
