Hi.All.I have cross flashed LG v40 Hong Kong version Rom Android 9 with the Korean Android 10 using lgup.
THE Rom was installed but I lost radio.no signal. So then on the advice of a friend I flashed partition dl modem a and modem from a eu version android 9 .and when the phone rebooted it shows security warnings and says all slots are unbeatable. Any way to put ut in download mode so lgup can identify.Any easy way out.thx

You need laf_a and laf_b partitions from HK 20a firmware

Then partitionDL 20a kdz
Then refurbish 20a kdz again to restore cellular.

Is there a way to identify region of LG V405EBW?
I did flashed both EU and HK KDZ but still no signal. I totally forgot to backup my firmware and now my phone has no signal :(
