Why is my device’s model not detected in LGUP?
Make sure your devices chipset is supported by UPPERCUT. All models and software variants may not be supported even though chipset is listed.
If you are using a properly working device with UPPERCUT but your device is still not detected in LGUP.you may have a “corrupted” misc partition…
As a last resort it has been confirmed in post #70 .That wiping misc will boot into download mode allows the device to be detected with UPPERCUT + LGUP 1.14. This may not work always and without rooting you can’t do this.
Why does this TOT file keep failing?
In most cases you’re either trying to downgrade and it has been blocked by your phones download mode (not anti-rollback fuse.. that is different)… OR you are trying to use a custom-made TOT file which is not official or signed by LG. Flash an official KDZ instead. Do not ask for KDZs in this thread.. not the place.
LGUP cannot detect my Device, shows the device as unknown model but correctly shows the comports
