LG-E403 PSU power up & data recovery
Hi! I have an old LG-E403 mobile phone. I want to retrieve my data but the phone wont power on. The battery is a bit swollen so I removed it, soldered 2 wires on the battery pins and connected them to a power supply unit at 4 Volts. I also soldered a 47Kohm pull down resistor to the middle pin which is the battery thermistor.
When I hold the power button the PSU current goes from 0 to 0.36. The screen stays black and as long as I release the button the current goes again to 0.
I would really like to save these data. Could anyone help me?

@alextevre I do not have anything about a E403. I have an E400 and E430 for the Optimus series. Just double check your model number for us so we can check for the schematic.

@oldturkey03 You are absolutely right, I misstyped the model. It is the LG-E430
