I have flashed my lg v40 (sim-unlocked) from android 9 sprint, to Korean version of android 10. There was no sim signal, everything else worked fine. I wanted to try other version of android 10 (Korean), Since, somebody suggested, that newer firmware might be the reason for no sim signal. But, I can not install any other firmware through LGUP, it gives error - error: 0x6004 Can anybody suggest how to install older version of android 10 through LGUP? I want to get my SIM signal back, so if there is a way to get it back please suggest as well
