[Urgent Help Required!] Phone boots, but no download mode or recovery! topic

Hi,

Have a weird situation, but try as much as I may, I'm unable to resolve it.

My phone is rooted (international D802) and was running fine. Had a screen issue and got it replaced at the service center but their system identified my phone as a rooted device, and a couple of days later the problems started.

The issues I'm facing right now:

1. The phone doesn't charge when switched on, at all.

2. The phone doesn't reboot either.. not instantly anyways. If powered off, or rebooted, the phone doesn't turn back on, it just goes dead. It does boot again though if tried after a couple of hrs.

3. The phone charges when its off (shows no light or indicator though, like its bricked)

4. Cannot go into either recovery or download mode. Coz the phone doesn't boot when restarted or when i try to reboot into recovery.

5. When it does magically start after a few hrs (upon long pressing the power button), even if I try to go into download or recovery via the vol keys, it just boots to android.

6. The phone is recognized properly as LG G2 under windows and all the drivers install too.

7. The phone isn't recognized under Linux... tried both Ubuntu and Knoppix.

Travelling out of the country in a few days, really need to sort this out.

Any and all help/suggestions will be greatly appreciated.

Thanks in advance :)
