RINO failure on first start

Just finished assembling RINGO together with my son, a lot of fun, thank you!
After first boot - it went properly, except the “on” button did not trigger from under the screen but worked from the bottom right corner. So after that all looked good and the main menu was on the screen, but when we tried to run first application - the Snake game, RINGO rebooted and never booted again - only shows first “Loading…” screen since then :frowning:

Serial monitor on reboot:

OK

next alarm: 99

module inserted

SIM NOT INSERTED

Serial1 up and running…

When Re-uploading the ‘Default Ringo software’:

Maybe this is related to the soldering on the first pin wi began with and obviously screwed. Just wondering if we ditched the whole board or worth it another try?..

In the end I needed just to remove the extra solder shown on the pics, and it fixed the problem!
