SIR ANDREW TM PLEASE HELP

phone not detected comports not showing when port check test enabled

[andrew_tm]

Install LGUnitedMobileDriver_S52MAN314AP22_ML_WHQL_Ver_3.1 4.1.exe from support and connect phone in Charge Only or MTP mode.

Connect phone direct to PC without any USB hub and box. I think you use some hub or connect phone in box port and after reboot software can't open phone port.

If this not help make next:
1. Read QCN
2. Put manual phone in Download mode(Vol + and insert USB cable).
3. Make Security Reset.
4. Write QCN.
5. Make IMEI 0 Fix.

It's possible that the bootloader is protected by one of those download mode protection apps like "KillSwitch" or "PayJoy" etc, or just the wrong d/l mode driver is loaded (which is most likely). You could also try a P999/910K resistor d/l cable to force it into download mode.

Once fully booted into the OS, you'd have to enable "ADB", "Port Check", and "MTP" to expose the diag ports.

This cable ignore KillSwitch ?

No the P999/910K cable will NOT be able to force the normal d/l mode, it will just boot in KillSwitch mode, but the QC EDL cable will boot it in low level d/l mode. Problem is finding the correct bootloader code for that particular chip. Or must make test point connection on the motherboard.
