If the device shows "Null" IMEI, attempt a wipe of the EFS partition using LG UP first. If this fails, the issue is likely hardware-related (Baseband CPU failure), requiring microsoldering repair, not software repair. Avoid using "Free tools" or cracked software, as the V50's UFS storage is easily corrupted, leading to a "Hard Brick" that cannot be recovered without advanced JTAG/EDL equipment.
