After getting an r4 card, how do you find the latest firmware version and the kernel? Also, how can I get rid of a time bomb on an r4 card? I'm using the r4i gold pro specifically.
With so many R4 clones its a bit of a minefield, usually the shop you purchased it on will have a link to the latest firmware. Possibly this? http://www.r4isdhc.com/2014-r4isdhc-gold-pro/ The Wood Firmware can be used as an alternative on some cards to remove the time bomb: https://forum.romulation.org/threads/wood-r4-the-new-firmware-99-8-compatibility-ck3.39701/ if not you need to keep updating the firmware or setting the DS's date back to when the card works.
