Maybe your buttons not working?
May be u r right.. but I eliminitated that since I could have a fast boot and a nearly power on experience.. but still this does not mean u r not right.. how Can i test it. I don't know ?
Did u pull the battery yet?
You may have damaged something inside, even though you don't see much damage outside. The solder joints on surface mounts are very thin and may have cracked, and may be disconnected or intermittent. One way to test that theory is to heat the unit with a hair dryer and attempt to reboot. If you see a difference in behavior, then some mechanical connection has been compromised. There's probably very little hope of reviving the unit.
One other trick is to put it in a bag of rice for a day or two. Then try to re-start. Rice is a desiccant and will take up all moisture from the unit (your OnePlus came with a desiccant packet). The act of dropping the unit may have opened something and allowed moisture to creep in.
Someone's suggestion of lightly dropping it flat on a carpet is a good idea. This may jolt the connections in place. Drop it from both sides and see what happens. Even tapping the unit might help.
Your unit most likely suffered shock damage. There's probably a hundred places where there might be micro-cracks. If you're lucky, it may be just a thin ribbon cable that is loose. As a test, you might dismantle the unit and disconnect and reconnect all electrical connectors (thin ribbon cables, etc.). This is probably the most useful activity in trying to revive your OnePlus.
I have black screen and it has not been dropped as well
I have disassabmled as much as I can, including battery, and most of the cables inside. And then I assembled back by carefully pressing all the connector to the board. and Also I tried to apply plressure on the device from diffferent parts, for the case that there might be a slight connection issue somwwhere inside.. but no effect. So I left in on charger lastnight and will see tonight after charging for 18 + Hour. somebody has experienced good results after this. Do you have any suggestion about a charge, rest procedure ?
Have you checked the power and volume buttons for any short or open conditions ?
Strange as it may seem, the battery itself might have been damaged. A dropped battery may suddenly lose it's charge. When you dismantle the unit, check the voltage on the battery. It should probably be somewhere near 5.2V.
24+ hours of charging and then trying to power on did not work. I tried on a windows 7 and a windows 8 machine to see if it they react to phone, no go.. SO I hooked up to charger again, and tonight may be I willl try on a windows 10 machine, as it worked for someone, and also may be that hair dryer heating trick.. Or should I set my self to say goodbye to my lovely opo ...
I dont have any clue sorry.
Hope for best and prepare for the worst. Just remember, the more drastic the symptoms, the more simple the solution.
Did you solve this problem? I just dropped my phone today and I have almost same symptoms as you (black screen, no response to anything). Only thing is that I have not seen any signs of life (no logo, no vibrations ect.), but it gets hot when i charge it.
Hope you found a solution which will help me to!
Hello! I dropped my OPO last night and now it won't power up - I am not too fussed about the phone but I didn't back up any of my photos. Is there a way I can try to get it to turn on? I have tried the power button down for 5 times but there is nothing. I would appreciate any help!
@Gonzo01, @Reboot101? Could you offer some guidance here?
seems he already tried all. the only thing left is really serious repair, like re-soldering all connectors, terminals, checking connectivity of all wires, etc...
Press the power button + volume down for 3 min. If it turns on, you are solid. If not, I have bad news for you .
Hi, any updates? Did you maybe give your OPO to someone to do diagnostics on it? Or you put it away and forgot about it?
Thanks in advance for a response.
