[Q] HTC repaired phone - Developer Edition Boot Loop again - never rooted/flashed
EDIT: So i sent my phone in for repair, received it back a week later. Updated it to 4.3 immediately after i received it back. Less than a week of using it, the same boot loop problem is happening again. I am on my wits end, I don't know exactly what i am doing to make the phone to go into a boot loop. i haven't flashed any roms nor done any modifications to it, just installed the 4.3 through the System Update in the settings.
Can anyone help? I don't want to keep paying to ship my phone back everytime this happens.
One thing though, right before the boot loop problem happens, the phone will warn me that it will shut off in 10 seconds, that telling me to hold down a button to restart it. This specific warning happens before i shipped in my phone and after i received back my "repaired" phone...
The phone doesn't charge when plugged into the wall electrical outlet or through usb, it will just turn on and proceed into boot loop over and over again.
HTC One Developer Edition 64 GB. Latest Android 4.1.2 official update. Never rooted/flashed/modified, I've only installed the system update through the phone.
I was texting on the phone and then it warned me that it will shut down in 1 second and then it rebooted. It has been stuck in the boot loop for the last few hours now.
I've tried holding the Volume Down button to boot into Bootloader screen, and it will only stay in that menu screen for 4 seconds and then proceeds to reboot again. It doesn't allow me to select the menu choices when press Vol up or Vol down buttons. Nothing happens.
I've called HTC support and set up a warranty device repair service ticket. Before I send the phone in for diagnose, is there anything else I should try? I've attached a pic of the Bootloader screen. Thank you.
