If you are a LG G3 user, you might be tempted to update to marshmallow, seeing the updates available through LG PC suite. Please don’t !
If it happened you already did, you might now end up in a situation like a lot other LG G3 users, where the phone would bricked at bootloop. Basically, the phone would infinitely restart. However, it never restart completely, where it just keep relaunching till the boot screen, then off and reboot till the boot screen again.
If you are already in above situation, my experience here might help. I have encountered this during the weekend, and almost gave up to customer service centre for last resolt. Then somehow below trial worked !
(Leave the power button aside, you never need to touch that button during this whole procedure.)
- power off the phone by removing the battery
- with the phone still off, plug the usb, connect the phone with PC
- with LG PC suit opened on the PC, and the phone still off, just hold the Power UP button for few seconds, this move the phone into download mode
- At LG PC Suite, Under “Mobile Devide” menu, there is this option called “Restore upgrade errors”. click it, it will try to connect the phone, download the patch to revert previous update. wait till it finish, your phone would be auto restarted.
In case above steps didn’t work out on first try, try another one or twice. It could have patched multiple times, if you phone is moving from lower lollipop version.
Let me know if it helps !
