If the Nokia Software Updater tool doesn't work for you, you can try using the Nokia Recovery Tool. Here's how:
using 7-Zip or WinRAR into a folder named Nokia_C30_Firmware on your desktop. Do not rename any files – the flash tool expects exact names.
⚠️ Always download firmware that matches your exact model number (TA-xxxx) and region to avoid hard bricking.
Official stock firmware can sometimes be found on specialized databases like HardReset.info
