My Polaris seems dead.
No response with the following key combination:
# power button

I removed the battery during 1 hour.
I have no led indication when I connect the device with power adapter.

Nothing happens, no led or other sign of live
I checked also the pins in the USB port, but those seems in the correct position.
May be the internal connection is broken?

USB-Issue

Hello
My Optimus3d doesent get recognized by usb (w7) anymore. The battery is loading but i cant access the phone. I tried it on 3 PCs with 3 different usb-cables.

my advice
remove usb cable
turn off your phone
remove batery
push some time power button
batery back in phone
open B2CAppSetupp
conect usb cable
wait to apear battery charging proces
then push in the same time volume up and power wait 8-9 seconds the screen go black... in thins time the B2CAppSetupp wil find some driver if not read more
wait a little time 10 s
repeat again "push the volume up and power" the phone will reset wait again 8-9 seconds.
this worked for me

What do you mean when you say the battery is loading? You mean it shows the battery is charging via usb?
Have you tried going into the phones settings and ticking the usb debugging box in the applications/development section? It may help though shouldn't be needed.
Also try a different usb cable in case yours is damaged.

yes, with loading i mean that it shows the loading battery icon on top right on the screen.
I tried enable/disable the usb-debug aswell as the massstorage thingy.
and as i said in the first post, i tried 3 PCs and different cables.
The only other thing you can do is connect to pc run lg pc suite on computer and from there it has a link to download usb drivers off lg website and you can reinstall the drivers.
Does your phone say "usb connected" when plugged into pc?

Elephone P3000s not working

My phone only shows the the elephone 2 e sign when I turn it on. I have tried pressing the on and volume key when I turn it on but nothing happened. I have followed some instructions on the elephone manufacturer site about installing drivers to my computer and then trying to reinstall the firmware. Unfortunately my computers (I have tried on three different ones) does not identify that a device is connected to the computer. Therefore I can't proceed to install the driver as according to my computer it is not installed. I have tried 2 different leads as well. I would be grateful for some help as I have no idea where to go from here.
Facing a similar issue, and since there's still no reply to this thread, I would like to add up a few findings I have on this matter to maybe help others and get helped.
My P3000S is also reaching the Elephone logo and displays it for a minute and then restarts, repeating the process (aka boot-loop).
The same happens whether it is connected or not connected to the charger/computer through a USB cable. (I've tried new cables but that's not the case).
When disconnected I can stop the boot-loop only by holding down the on/off button for a few seconds (or removing the battery of course).
When connected to the the charger or computer through the USB cable I have no way to stop the boot-loop (holding down on/off just restarts it).
Now with the battery removed..:
If I connect it to the charger/computer, though the charging red light turns on normally, I can't turn on the phone using the on/off button.
However, when connected through USB to a windows computer, I can see in the device manager that, right when I connect the phone it shows up as "Mediatek Preloader USB VCOM Port" under COM ports group, for 1 second and then disappears as if it was disconnected. There's no repetition here I have to manually hold down the on/off button or disconnect and reconnect the phone from the cable to cause this to happen again.
So, I am unable to flash anything nor turn the phone on because I practically only have 1 second of its presence in my devices list.
Also, I have tried all possible combinations with the volume up/down keys and the on/off button in order to enter recovery mode, with no success..
In case anyone has faced something similar or has any ideas on a possible fix on this phone please feel free to reply.
At last a reply to my initial message. Unfortunately it was someone with the same problem as me. I took out a paypal case against the person I bought the phone from and eventually they repaired it. Unfortunately they never told me how. To make matters worse it broke again within 2 months. The phone is now sat in a draw doing nothing. I have given up on it and will never buy another Elephone phone again.

Side Buttons flex cable broken. How to Turn phone on?

Hello XDA Members.
As the title says, the flex cable for the entire right side of the phone is broken (meaning no FP sensor, power, vol +/-, or shutter buttons). The phone ran out of battery and turned off. Is there a way to turn the phone on without the buttons? (maybe by disconnecting the battery while charging, similar to older models?)
ADB is not detecting the phone, USB Debug was probably not enabled
I'm looking for a replacement flex cable, but they're very difficult to find as this model wasn't sold officially in my country. Can't order online either sadly (3rd world country)
Solved.
Here's how for future reference if someone encounters a similar issue.
1. Disconnect battery and reconnect it
2. Download and install Xperia Companion Tool from Sony (tested on Mac, but the Windows version should work as well)
3. Choose Repair Software/Xperia on the Companion tool
4. Connect phone to computer using a USB cable
5. Disconnect phone when the Xperia splashscreen appears.
Done.
EDIT: Nope, phone froze and tried this, didn't work again.
