Hoi SlimSomething, To answer your question: Yes, the Nintendo eShop is Region-locked and is determined by both the Nintendo 3DS and the Nintendo Network ID used on the 3DS to access the shop, which is saved onto eShop servers. Hopefully, this can be of assistance!

Hoi Nandan Raj, A late response here, but your issue could have used some more information. Unfortunately, BlackBerry has since ended support for all mobile devices and has shutdown all servers related to those devices, including the BlackBerry Classic. If your issue, was trying to set-up your BlackBerry Classic and are not able to pass the Wi-Fi screen, this is due to the server shutdown and your device will not be able to properly set-up due to that. BlackBerry: End-of-Life Announcement Not the news to hear about a device you use, but hopefully this helps with your issue.

Hoi Denny, Late response here, but when you say "cannot bootup" are you at least getting power or not? If you are, then you might need to 'flash' the latest autoloader for the Key2, which is available at CrackBerry: KEY2 ACQ160 Autoloader (May 2020 patch), since BlackBerry no longer offers support to mobile devices anymore. If you are not getting power, then you might either have a power issue or a faulty board. Hopefully, this can be of assistance!
