I tried a new battery and ddiferent chargers but there is not any signal
A little more info would be good so we can help you.
- What happened before?
- Did the battery drain to 0%?
- Did the phone fall?
- With “not any signal”, do you mean no LED, no vibration and no backlight on the display?
- Can you still get into #dic:fastboot and detect the phone from your computer?
Shooting blind here I’d try to #disassemble the screen and clean the contacts.
The problem was solutioned with step2. Thank you!
Step 1: try out different chargers and check your USB port
First things first: let’s make sure your charger and USB cable are not failing. We wrote a support article about charging equipment, please read it carefully and make sure to follow every suggestion listed. You can also to try and charge your Fairphone using a PC or a laptop.
Another thing you want to check is the USB port on your FP2. Make sure it is not too dirty or full of lint. You can clean it up using a very thin needle, for example. Lint build-up can disrupt the connection between the cable and the charger, keeping you from charging your device.
Do you have access to a second FP2? If you have a friend who owns a Fairphone, you should try the following:
- Does your phone charge their battery?
- Does their phone charge your battery?
NOTE: Do make sure to try everything you can. The results of these tests can make the difference between having a working device within a day - buying a new charger or cable is easy - and sending the phone to us for repair, which may take up to two weeks.
If all fails, don’t panic and keep reading.
Step 2: the boot loop test
Remove the battery and connect the device to the charger. At this point, the device should enter the following loop:
- The Fairphone logo appears on the screen.
- The display turns off and the LED on the top left corner shortly blinks red.
- The phone vibrates.
If your device doesn’t behave as described, please take note of what is happening. This information might help us understand what is failing.
Step 3: remove and reinstall the bottom module
Open the device and remove the bottom module. All you need is a Phillips # 0 screwdriver.
Once the module is out, we’d like you to take some pictures.
You can then reinstall the module inside the phone. Before installing the display, please take some extra pictures:
Now reassemble the phone and test it one more time by performing steps 1 and 2.
Do you have access to a second FP2? If you have a friend who owns a Fairphone, you should try the following:
- Install their bottom module inside your phone. Does your phone charge now?
